Abstract
Pseudomembrane colitis (PMC) and antibiotic associated colitis (AAC) are acute disease of the colon. In the case of in adequate treatment, the disease will often become chronic and my lead to the dysplasia of the epithelial cells of the infected areas. Previously because of poor knowledge. Treatment in this case, one of the method for treatment was surgical ablation of the large intestine while the patients could have been treated with oral vancomycin. In this study the following results were obtained: Out of 2517 enterocolitis patients under study, 1384 were men and 1133 women. By anaerobic culture method, 132 cases C.Difficile were isolated from the total samples and Hela cell culture method, toxin was determined in 36 samples (1.43%).

Abstract
The lower respiratory tract is vulnerable to infection by a wide variety of microorganisms, because it is one of the organ systems which communicate directly with the environments. Although viruses and fungi can cause lower respiratory tract infections, bacteria are the dominant pathogens. Among bacteria the common causes of lower respiratory tract infection is Streptococcus pneumoniae, Mycoplasma pneumoniae, Staphylococcus aureus, Streptococcus pyogenes, Haemophillus influenzae and Legionella species. This study has been carried out to investigate pathogenic bacteria isolated from sputum of 220 patients with suspected pulmonary infection. The results were obtained as follow: Mycoplasma pneumoniae: 17 cases 22.7 percent, Mycobacterium tuberculosis: - cases - percent, Streptococcus pneumoniae: 17 cases 22.7 percent, Klebsiella pneumoniae: 12 cases 16 percent, Haemophillus influenzae: 10 cases 13.3 percent, Staphylococcus aureus: 15 cases 20 percent, Pseudomonas aeroginosa: 4 cases 5.3 percent.

Abstract
It is now generally recognized that anaerobic bacteria may be involved in most human bacterial infections that follow any form of surgery or are related to those body sites that have a large anaerobic population. Anaerobes must therefore be sought in a wide variety of clinical specimens. In this study, 3015 specimens of patients (1684 male and 1331 female) with periodontitis (160 cases), abcess (305), sinusitis (33) and enterocolitis (2517) wer investigated. The anaerobic isolates from patients with periodontitis were 244 cases, abscess 32, enterocolitis 42.

Abstract
Background: Metabolic syndrome is a complex of metabolic disorders that contemporary occurrence in a person is more than the risk of occurrence of each one separately. this syndrome has gained researcher's attention because of its relationship with cardiovascular disease and diabetes type II and its high prevalence in populations
Methods: A cross-sectional study performed on 1110 participants, 20-74 years old with cluster sampling. All of them had interview and special questionnaire were filled. Epidemiologic and demographic data were about hypertention cardio vascular disease and related lab data.
Results: The prevalence of metabolic syndrome was 32.1% that it was significantly more in women than men .this prevalence increased with age and BMI in both sexes .the most common metabolic disorder was TG>=150. 19.2% have none, 21.1% have one, 27.6% have two, 20.8% have three,9% have four and 2.3% have all criteria of metabolic syndrome.
Conclusion: Approximately one third of population of Yazd have metabolic syndrome and according to other statistics of Iran, this prevalence is more than U.S and Europe. It seems there is an urgent need for a national multicenter program for determinding risk factors for metabolic syndrome.

Abstract
Background: Premature coronary artery disease (CAD) has a familial predisposition and
occurrence. We determined the prevalence of CAD and related risk factors in individuals
with a history of premature CAD in their first-degree relatives.
Methods: This study included 700 healthy individuals with a history of premature CAD
in their parents or siblings in Tehran Heart Center in 2003-2004. History of smoking,
diabetes mellitus (DM) or hypertension was taken. Fasting levels of blood sugar (FBS),
triglycerides (TG), cholesterol, LDL and HDL were measured. Noninvasive studies for
CAD were performed with resting echocardiography (ECG) and ECG with exercise
tolerance test (ETT). Patients with positive findings for ischemia in these tests underwent
a myocardial perfusion scan and if positive proceeded to coronary angiography.
Results: The mean age of our subjects was 35.2 (15-65) years. DM was found in 5.3%,
smoking in 14.7%, hypertension in 20.6%, cholesterol above 200 mg/dl in 39.9%, TG
above 150 mg/dl in 58.6%, LDL above 130 mg/dl in 38% and HDL below 40 mg/dl in
32.6%. In addition, 6.4% had ECG changes and 3% echocardiographic abnormalities in
favor of ischemia. ETT was positive in 7.3% and myocardial perfusion scan in 2.1%.
Coronary angiography showed 50-70% stenosis in eight patients (1.1%) and >70% in
four patients (0.6%).
Conclusion: High cholesterol, TG and LDL and low HDL were found among our
subjects. Risk factor determination in these individuals may prove to be beneficial.
Noninvasive tests for CAD yield low true-positive results and are not recommended in
the population as a whole. In certain subgroups, including those with persons older than
40 years and diabetic patients, these tests may be useful.

Abstract
Background: Anxiety is a complex phenomenon with important results. In fact anxiety is a biologic process that has repetitive biological and physiological effect on the biological structure of brine. From long time ago anxiety and fear has bean one of the important psychological issues and for the control of anxiety different drugs with different mechanisms have been presented and understanding mechanisms that are involved lead us to newer drugs discovery. In this research the effect of morphine on the anxiety in the adult Male rats in the Ventral Tegmental area (VTA) and Nucleus Accumbens (NAc) was studied.
Methods: The elevated plus maze was used in combination with the percentage of time spent in the open arms of the maze (OAT %) and the percentage of entries into the open arms (OAE %) to measure anxiety. Increases in the OAT% and OAE% indicate an anxiolytic effect (reduction in anxiety), whereas decreases in the OAE% and OAT% indicate an anxiogenic effect. Adult male rats, weighing 200-240 grams, underwent surgery. After five days, the rats were injected with saline and three different doses of morphine (2.5, 5, and 7.5 µl/rat). Experiment one included the injections into the VTA. In the second experiment, these injections were in the NAc. Behavioral tests were conducted between 12 pm and 4 pm and each animal was used once for each experiment.
Results: In the first experiment, although these doses of morphine injected into the TVA had no effect on the OAE%, a dose of 5µl/rat increased the OAT%, showing a decrease in the animals' anxiety. In the second experiment, doses of 2.5µl/rat injected into the NAc induced a significant increase in the OAT% and OAE%, there by displaying decreased anxiety in the animal. However, no significant change in the activity of the animals was observed.
Conclusion: As a Result of these experiments, it seems that different doses of morphine can decrease anxiety, probably through interaction with gabaergic system. |

Abstract
Background: Several randomized controlled trials have demonstrated the safety and efficacy of drug eluting stents (DES) in selected groups of patients with less complicated diabetes. We conducted this study to determine how an unselected group of diabetic patients in Iran fare following DES implantation.
Methods: Data were collected on 147 consecutive diabetic patients who underwent percutaneous coronary intervention (PCI) with the implantation of at least one DES at the Tehran Heart Center from June 2003 to September 2005. Clinical follow-up was performed by timely scheduled visits at one, four and nine months following DES implantation. Nine months of follow-up was completed for 94.5% of the patients. The primary endpoint was the occurrence of major adverse cardiac events (MACE), which include cardiac death, myocardial infarction and target vessel revascularization (TVR). In-hospital complications were the secondary endpoint.
Results: A total of 158 coronary artery lesions were treated with DES in 147 diabetic patients (mean age = 56.4±8.92 years, 57.1% were men). During the nine-month follow-up, MACE occurred in 3.4% of patients, with a myocardial infarction rate of 1.4% and TVR rate of 1.4%. Considering one patient who underwent TVR due to acute stent thrombosis following angioplasty (during hospitalization) the total number of TVR reached 3 (2%). Only one patient (0.7%) died of cardiac death, which occurred after the procedure and before discharge. In-hospital complications occurred in six patients (4.1%) five patients suffered from myocardial infarction.
Conclusions: PCI with DES seems to be safe and effective in diabetic patients. However, more studies with larger study populations and longer follow-up are required to confirm this issue.

Abstract
Background: Radiation to some parts of the heart is unavoidable in the therapeutic course of primary tumors in many kinds of cancer, including breast cancer. The aim of this study was to assess the frequency of acute and subacute cardiac complications following radiotherapy in patients with left breast cancer.
Methods: In this study, we enrolled 53 patients with left breast cancer who underwent mastectomy or lumpectomy between September 2005 and September 2006 in Imam Khomeini Hospital Complex, and subsequently underwent chemotherapy with anthracyclines (<450mg/m
2) and Endoxan plus taxane/fFluorouracil followed by radiotherapy. In all patients, electrocardiography and echocardiography were performed before initiation of radiotherapy, immediately after radiotherapy and again three and six months later to check for radiotherapy-induced cardiac complications such as pericardial effusion, valvular lesions, left ventricular dysfunction, conduction system disturbances and other variables.
Results: Thirty-nine patients completed the follow-up period. Among these, 10 (25.6%) patients experienced cardiac complications following radiotherapy. Among these, mild pericardial effusion in seven (53.85%) patients, mild mitral regurgitation in three cases (23.08%) and Right Bundle Branch Block (RBBB) in two cases (15.38%) were the most common complications. We found no correlation between cardiac complication and tumor dose, dose fraction and type of chemotherapy protocol. We noted no cases of new or more serious complications, such as cardiomyopathies or coronary artery disease, nor any changes in ejection fraction by the end of the follow-up period.
| Conclusion: In patients with left breast cancer, acute and subacute cardiac complications following radiotherapy are not serious and have no clinical significance. Further studies are needed for more assessments in this area. |

Abstract
Background: There are several evidences that genetic factors besides environmental triggers have important role in initiating the rheumatoid arthritis (RA). The aim of this study was to investigate the association of rheumatoid arthritis with different subtypes of HLA DR4 in Iranian patients.
Methods: In an un-matched case control study, 110 rheumatoid arthritis patients (case) and 56 knee osteoarthritis patients (control) of outpatient clinic in Shariati Hospital were entered to the study. After blood sampling from case and control groups, DNA was isolated by using salting-out method and HLA DR4 and its subtypes were detected. Association of HLA DR4 and its subtypes with rheumatoid arthritis, rheumatic factor and clinical manifestations of diseases was evaluated.
Results: Eighty nine (80.9%) of rheumatoid arthritis patients were female and 21 were male. Thirty four of the RA patients (30.9%) and eleven subjects from the control group (19.6%) were HLA DR4 positive (p=0.12). The most frequent subtype of HLA DR4 in RA patients was 0404 and in control group was 0401 (p=0.03). There were not statistically significant association between HLA DR4 and age of disease onset, family history, morning stiffness and rheumatoid factor. Joint swelling and tenderness had association with HLA DR4 (p=0.04 and p=0.03).
Conclusion: Although there were no statistically significant association between rheumatoid arthritis and HLA DR4, but prevalence of this HLA was higher in patients than control. It is possible that in some ethnics, other HLAs may have role in pathogenesis of disease.

Abstract
Background: Dopaminergic is the most important
neurotransmitter is fear. The dopaminergic mesolimbic pathway has essential
role in excitable behavior, and it's role in Parkinson disease. The aim of this
research in study, the effect of dopaminergic pathway in fear response.
Methods: The elevated plus maze was used in
combination with the percentage of time spent in the open arms of the maze (OAT%) and the percentage of entries into the
open arms (OAE%) to measure fear. Increases in the OAT% and OAE% indicate an anxiolytic effect
(reduction in anxiety), whereas decreases in the OAE% and OAT% indicate an anxiogenic effect. After
five days, the rats were injected with saline and different doses of sulpiride
and Bromocriptine.
Results: Results showed that intracerebroventricular
administration of sulpiride, in the doses of 5, 20μg/rat and bromocriptine, D2 agonist in doses 65, 95μg/rat produced
a significant effect comparing to sham groups (p<0.05). While intracerebroventricular
administration of sulpiride 15, 10μg/rat,
and bromocriptine 70,
80μg/rat,
did not show any significant effect comparing with sham group (p<0.05). In the current research
intracerebroventricular administration of sulpiride, D2 antagonist at the doses of 5, 10, 15, 20μg/rat and Bromocriptine, D2 agonist in the doses of 65, 70, 80, 95μg/rat were used and theire effect on
the fear behavior were studied.
Conclusions: The possible effect of Dopaminergic
system in the fear process, especially D2 receptor increase fear.

Abstract
Background: The relationship between Coronary Artery Disease (CAD) and the prevalence of Renal Artery Stenosis (RAS) has been demonstrated. Despite high incidence of heart diseases and high frequency of CAD risk factors among Iranian population, this relation has not been clearly determined. This study estimated the prevalence of RAS and its determinants in Iranian angiographic candidates. We also tried to find which risk factors of atherosclerosis are associated more frequently with renal artery stenosis.
Methods: In a cross-sectional study that was performed at the Tehran Heart Center, in Tehran, Iran, 146 patients who were candidate for angiography with suspected CAD were consecutively included. Selective renal angiography was performed following coronary angiography in all patients with established coronary artery stenosis and the presence and severity of RAS was evaluated.
Results: Prevalence of RAS in study patients was 25.3% (men, 13.7% and women 47.1%, (p<0.001). We found that only 6.2% of the patients had bilateral R.A.S. Also, RAS≥50% was found in 17.1% of patients. Regarding number of defected coronary vessels, two- and three-vessel diseases were found in 30.0% and 39.0% of participants, respectively. No significant relationship was found between the number of involved coronaries and the severity as well as side of RAS (p=0.716) Significant multivariate predictors of RAS were female gender (p=0.001), advanced age, (p=0.046) duration of hypertension (p=0.032) and baseline serum creatinine concentration (p=0.018).
Conclusions: Routine angiographic assessment of renal arteries following coronary angiography is recommended especially in women as well as those with long-term duration of hypertension or renal dysfunction.

Background: Neutrophil
Gelatinase Associated Lipocalin (NGAL) is a new biomarker which can predict acute kidney injury (AKI) in critically ill patients.
Usefulness of NGAL in the early diagnosis of all types of AKI is under question. We
hypothesized NGAL is an early predictive biomarker of contrast-induced nephropathy (CIN).
Methods: In this process evaluation study, we enrolled 122 patients (Mean age 59.7±10.8 years) undergoing elective
angiography/angioplasty with contrast media during April to September 2009. Serial urine samples were
analyzed in a double-blind fashion by NGAL enzyme-linked immunosorbent assay. CIN was defined as a 25% increase in baseline serum creatinine.
Results : The prevalence of CIN was 30.3%. Significant elevations in urinary NGAL concentrations were noted within 12-h and 24-h after the procedure in patients with CIN. NGAL concentrations after 12 hours was 90.62±105.63 vs. 27.6±45.8 ng/ml in patients with and without CIN, respectively P=0.0001, and 79.78±117.7 vs. 30.92±52.84 ng/ml, 24 hours afterwards P=0.002. Some patients had AKI after five days of exposure rather than the second day (P=0.0001). We found using a cut-off point
of 8
ng/ml with a sensitivity, specificity, negative predictive value and area under
the ROC curve
94%, 25%, 91% and
0.75 respectively
are good for the prediction of CIN in 12-h urinary NGAL and a cut-off point of 5.5 ng/ml with respective values of 97%,
24%, 95% and 0.70 for 24-h urinary NGAL.
Conclusion: Urine NGAL may represent a sensitive
early biomarker of acute AKI after angiography/angioplasty. We recommend the routine measurement
of NGAL in
high risk patients receiving contrast agents.

Background: The
goal of this study was to compare the efficacy of botulinum toxin type A (BTX-A) injection in the hamstring
and calf muscles with and without ankle serial casting in the improvement of
gait in children with cerebral palsy (CP).
Methods : This double-blind prospective clinical trial was performed on 25, 2 to 8-year-old children with
hemiplegic or diplegic CP in Tehran, Iran in 2010. The participants were chosen by simple randomized sampling and
were matched for age, gross motor function classification system (GMFCS) and type of CP and were randomly divided
into two groups: children in the first group (13) only received BTX-A injection, but the second group (12) received BTX-A and serial foot casting starting one week after the injection.
Results : Comparison of the gross motor function, right and left knee
spasticities and passive ROM of both knees between the two groups before and 1, 3, 6 and 12 months after the injections
were not statistically significant (P>0.1). Furthermore, comparison of the right and left ankle spasticities
and passive ROM before the injections and in1 and 3-month follow-ups did not show a statistically significant difference
(P>0.1),
but the differences were significant in 6 and 12-month follow-ups (P<0.05).
Conclusion: BTX-A injection
with serial foot casting vs. BTX-A
alone was more effective in decreasing spasticity and improving passive ROM in
the ankle of children with CP, but such injections in the
hamstrings were not useful in these regards.

Abstract
Background: Ascorbic acid (AA) is not synthesized in the brain but it is actively transported through blood-brain barrier by SVCT2 cotransporter and it is stored in high concentrations with heterogeneous distribution in areas such as nucleus accumbens shell (AcbSh) in the mammalian brain. Previous studies have shown that Ascorbic acid injection into AcbSh decreases feeding therefore, in the present study we evaluated the effects of oral Ascorbic acid pretreatment on changes in feeding upon its injection in AcbSh in adult male rats.
Methods: Sixty-three adult male rats (220-280 g) were divided into five treatment and five pretreatment groups. The treatment groups included the control (intact) group, sham-operated Ascorbic acid group that received normal saline as vehicle, and three other groups that received different doses of ascorbic acid (10, 50 and 250 µg/rat) by injection into AcbSh for four days. The pretreatment groups received Ascorbic acid (100 mg/kg) for 15 days via gastric gavage before receiving the aforementioned doses in treatment groups into intra nucleus AcbSh. Feeding measurement was repeated every 12 hours by automatic metabolic cage.
Results: The results indicated that all injected doses of Ascorbic acid (10, 50 and 250 µg/rat) into nucleus accumbens shell decrease food intake (P<0.05) in rats and oral Ascorbic acid pretreatment had no effects in this regard.
Conclusion: Our findings show that ascorbic acid is an effective factor in feeding regulation. Oral pretreatment seems to have no influence on the central effects of ascorbic acid in the nucleus accumbens shell.

Abstract
Background: Toxoplasma gondii, is a mandatory intracellular protozoa, that many people worldwide are infected with. In children, the infection enters central nervous system and leads to inflammation of the gray matter. Autism, is a complex develop-mental disorder, altering social communication, with unknown origin. Neuropathologi-cal changes in autism are the same as those occurred in brain toxoplasmosis. The objective of this survey was to evaluate positive serology of toxoplasma gondii, in autistic children.
Methods: This case-control study was done on 3-12 years old children, referring to the neurology and psychiatry sub-special clinics of Baqiyatallah hospital and also autistic children of Omid-e Asr and Navid-e Asr general rehabilitation centers in Tehran, Iran. The study performed at 2012-2013. Forty autistic children were placed in the case group and 40 children, suffering from no neuropsychiatric disease or other ones, were placed in the control group. A folder, containing demographic data, type of the disor-der, onset of diagnosis and child characteristics at birth, such as time of birth (preterm/ term) fulfilled for each child. Sampling was done with 5 ml blood, for determining IgM and IgG antibody levels against toxoplasma gondii, using ELISA method. Data ana-lyzed by the software SPSS ver. 17 and descriptive and analytic analysis were done, us-ing central and dispersion indexes and also chi-Square test.
Results: The autistic group contained 34 boys and 6 girls (85 and 15 percent respectively), with the average age of 6 (±2.71) years old [minimum of 2.33 and maximum of 12]. The average age at the time of diagnosis was 4.01 (±1.87) years old. 87. The non-autistic group contained 17 boys and 23 girls (42.5 and 57.5 percent respectively), with the average age of 5.67 (±3.09) years old [minimum of two and maximum of 12]. IgM and IgG serology of all autistic children were negative, while in non-autistic group, 2.5 percent (1 child) were positive and 97.5 percent (39 ones) were negative. There were no statistically significant difference among these two groups according to the serology results.
(P=0.31).
Conclusion: There was no statistically significant difference in comparing positive se-rology of toxoplasmosis, between the two groups. However, to obtain a perfect result, a larger sample size are required.

Abstract
Background: Human brucellosis is a significant public health problem in many middle east countries including Iran. Brucella organisms, which are small aerobic, facultative intracellular coccobacilli, localize in the reproductive organs of host animals, causing abortions and sterility. They are shed in large numbers in the animal’s urine, milk, placental fluid, and other fluids. Dairy product from raw milk are a potential threat to public health in endemic developing countries. The gold standard for the diagnosis of brucellosis is isolation of Brucella species. However, isolation Brucella species is time consuming and needed to level 3 biocontainment facilities and highly skilled technical personnel to handle samples and live bacteria for eventual identification. Handling Brucella species increase risk of laboratory infection. Polymerase chain reaction (PCR) with high sensitivity and specifity overcomed to these disadvantages. The aim of this study was to detect Brucella species in milk from dairy cattle farms in Kerman province, Iran by PCR technique.
Methods: Forty and eight bulk tank milk (BTM) were collected from October 2015 to March 2016 from 48 dairy cattle farm including 4200 cows. DNA of milk samples extracted by lysis buffer and proteinase K method. All milk samples were examined by PCR to detect Brucella-specific DNA targeting IS 711. Positive samples must be showed 317 bp amplified, corresponding to the expected size of the IS 711 genome region in all Brucella species.
Results: Using IS711 primer were detected in 4 samples (8.3%) Brucella spp. from 48 BTM samples in this area.
Conclusion: The results indicate that brucellosis by Brucella species is endemic in the Kerman province dairy farms. Consumption of raw milk dairy products by individual farmers operating under poor hygienic conditions represents an high risk to public health. The need for implementing control measures and raising public awareness on zoonotic transmission of brucellosis are recommended. Vaccination of cattle is recommended for control of bovine brucellosis in enzootic areas with high prevalence rates.

Abstract
Background: Cardiovascular disease (CVD) is the most common cause of death in the world that is mostly due to vascular disease. Myocardial infarction (MI) is the most lethal form of coronary heart disease Which is increasing in developing countries. This study was done to calculate and compare lost years of life due to death and disability for the most important cause of death (myocardial infarction) in the studied population.
|
Methods: This cross-sectional study was carried out in Urmia university of Medical Sciences in Western Azerbaijan Province, Iran during 2012 to 2013. Confirmation of the occurrence of myocardial Infarction in hospitalized patients was based on clinical symptoms, changes in electrocardiogram and increases of cardiac enzymes (CK-M Band Troponin). The burden of health from Myocardial Infarction was calculated- using the disability adjusted life years index (DALY). The morbidity data of MI was collected from myocardial infarction Registration System Department of Health, and mortality data were extracted based on death registration ICD10 (I 20-25).
Results: The total occurrence of MI was 7235 patients (60.6% men and 39.4% women) with the mean ages of 69±15 years. Number of disability adjusted life years (DALY) caused by MI was 53804 years (17.7 per thousand people) and the portion of early death Years of Life Lost (YLL) due to premature death was 52170 years (17.1 per thousand people), and Years of Life Lost (YLD) due to disability resulting from the disease was 1634 years (0.54 per thousand people). The disease burden in men was more than in women, and the greatest burden was in the age group of 80 and above in both sexes. Prevalence rate of the MI was estimated 376 (Per hundred thousand people) and the MI accounted for 18.8% of all causes of death.
|
Conclusion: The high burden of myocardial infarction, especially in men, raises the incidence of Myocardial Infarction a health priority and the need for proper planning in order to take effective measures for the prevention and treatment.

Abstract
Today, nanoscience has grown and developed in various medical and therapeutic areas, including cancer treatment. On the other hand, cancer and its types have been rumored and inclusive and many people suffer from this fatal and deadly disease. Currently, existing therapeutic method, including chemotherapy, radiotherapy, and etc., along with the therapeutic effect, cause complications that are unpleasant for patients. Hence, scientists and researchers are looking to develop and improve treatment options and methods to deal with this serious disease. Today, nanoscience and nanotechnology have become widespread, and its various fields, including nanoparticles, are widely used for a variety of applications, especially for delivery of drugs and diagnostic items and imaging cases. Nanotechnology-based release systems have a significant impact on the release of cancer drugs. Advances in bio-materials and bio-engineering are contributing to new approaches to nanoparticles that may create a new way for the improvement of cancer patients. Nano-technology in the drug release system has had a great impact on the selection of cancer cells, the release of a targeted drug, and overcoming the limitations of conventional chemotherapy. At the present many drug delivery systems are now made of nanoparticles, and various substances have been used as drug-stimulating agents or as a reinforcing agent to improve the efficacy of the treatment and durability and stability and also the safety of anticancer drugs. The materials used to release cancer drugs are divided into various categories such as polymer, magnetic, biomolecules. In the meantime, polymer nanoparticles have been organized in the carriers of anti-cancer nanoparticles due to the process of easy production, biocompatibility, and biodegradability. Although the loading of hydrophilic compounds is still confronted with limitations, due to the diversity of nanoparticle structures, it is possible to encapsulate various molecules. Also, surface changes and modification such as binding to antibodies and target ligands can also be applied to these materials, to act as target drug delivery to increase the effectiveness of treatment process. In this article, we will have an overview of cancer disease and cancer drugs and also nanoparticles and their contribution to cancer treatment.
