Abstract
In view of the rapid expansion of contact lens amongst the users, new dimensions have been added to the domain of ophthalmology: Giant papillay conjunctivitis, a disease caused by different kinds of contact lens, appears weeks or months after they are used, although some patients are struck years later. The predominant symptoms are increased awareness of lenses, ocular itching, blurred vision and excessive lens movement. The predominant signs are the formation of papillae, the presence of excessive mucus, and contact lens coatings. The syndrome occurs mostly with the soft lens and is more intense. Other independent studies show that the rate of prevalence of the disease with soft lenses and hard lenses is 10% and 5% respectively. The study comprised 550 soft lenses and 150 hard lenses. The diagnosis of the disease was based on the symptoms and signs of the disease. Eleven percent of the patients using soft lens and 4% of the patients using hard lens had the disease at some stage. Almost all of the patients were using dirty and low grade lenses. The therapy protocol of the disease consisted of changing the polymer type of the lens and administering cromolyn 4% drop. In cases that the therapy was unsuccessful, a temporary suspension of the lens and administration of cromolyn 4% was recommended before using the new lens.

Abstract
In 100 healthy, adult and female mice weighing about 20 to 25 g each, paris of full thickness and nearly symmetrical cutaneous wounds, 100±15 mm² each were created in dorsolumbar region. Mice were divided into 3 groups randomly, group 1 (Right wound exposure), group 2 (Left wound exposure) and group 3 (Control). Wounds were exposed to laser He-Ne (632.8 were length and 16 mw constant power) for 10 days, 250 seconds each day. The control group mice were in equal situation except for the exposure wound were measured in size once every 2 days. Also biopsies were made from a clear number of cases once every 3 days from microscopic evaluation of wound healing stages. The difference in wound healing between the test groups and controls was significant as confirmed by statistical methods (E.g. one way ANOVA and SCHEFFE) with (?=0.05) and proved by microscopic findings. This experiment were made in "Blind" form. There was no significant difference in wound healing between 2 sides in test groups, this strengthens the idea that laser therapy causes the release of systemic wound healing factors

Abstract
Botulinum toxin produced by Clostridium butolinum in one of the most fatal toxins known. Botulism is the name given to condition produced by this toxin. In recent years the diluted form of this toxin has been produced in injection form and used for treatment of hemifacial spasm and blepharospasm. This toxin blocks neuromuscular junction and inhibits acetylcholine release. In this article we reported 36 patients suffering from hemifacial & blepharospasm treated by injections of botulinum A toxin. 85 to 90 percent of patients responded well. The common complications of this drug were ptosis, hemifacial paresis, burning of the mouth and discoloration of the injection site. Generally speaking the patients preferred this toxin to taking oral medications which were less effective.

Abstract
L-fucose (6.deoxy. L.galactose) is the only monosacharide which is placed in non reducting position of glycoproteins structure in L-deoxy form. L-fucosidase and fucosy 1 transferase directly take part in the elevation or decrease of sorum L-fucose levels. Tumors may directly induce enzymes that release L-fucose from glycoproteins formed in the neoplastic tissue, or the glycoproteins may be released indirectly as a result of body-defense metabolic secretion of glycoproteins and their filtration in glomeruls, and has a close correlation with glomerular filtration rate (GFR). In this study we compared urinary L-fucose of 30 known cases of cancer versus 40 healthy people. Fifteen patients had Gastrointestinal (GI) cancer and 15 patients Gyneclologic (Gyn) cancer. There was significant difference between urinary L-fucose of patients with GI cancer and controls (P<0.01), and also we saw the same result (P<0.01) in Gyn patients in comparison with controls. Significant elevations of urinary L-fucose, in GI and GY cancers may lead us in the way to further evaluation of its relationship with L-fucose levels to make its early diagnosis and better prognosis in susceptible individuals and those at a high risk of developing cancer, possible.

Abstract
Twenty cases of isolated optic neuritis (15 female, 5 male) were studied and followed for several months to years after the initial attack. The mean age of patients was 23 years (range: 15-29 years). The most frequent clinical manifestations were decreased visual acuity and blurred vision. A complete neurological examination was performed. In 15 cases (75%) the initial brain MRI was abnormal. In fourteen cases, other signs of multiple sclerosis presented in one month to eight years following the initial attack of optic neuritis eleven of the latter cases had an abnormal initial MRI. Acute optic neuritis can be considered a presenting feature of multiple sclerosis, particulary in the presence of an abnormal brain MRI.

Abstract
Tumor angiogenesis shown by Microvessel Count (MVC) or Microvessel Density (MVD), is assessed by several studies as prognostic factor in some types of tumors, and also in colorectal carcinoma. This article is payed to correlation between clincopathologic factors and tumor angiogenesis. In this study, immunohistochemical techniques are used for vascular evaluation in specimens from twenty-nine colorectal carcinoma, and stained for Factor VIII-Related Antigen (F8RA) by using monoclonal antibody. Uni and multivariate analysis disclosed that total MVC was higher in tumor [76.3±33 (×100=2.5 mm²/field) and 29.8±11 (×200=0.785 mm²/field)] than in normal tissue [37.7±15.8 (×100) and 17.6±7.8 (×200)], (P=0.022, P=0.000009). Microvessel quantification was significantly higher in stage D (115±36.6, ×100 and 26.7±6.4, ×200, P=0.002 and P=0.04). In this study MVD has correlation with vascular invasion (P=0.024, ×100 and P=0.007, ×200), the mean tumor vessel count although was increased with clinicophatologic findings such as age<60 years, male, right colon involvement, infiltrating type, mucinous carcinoma, transmural penetration, grade III, lymphatic and perineural invasion, but was not statistically significant. Lymph node and hematogenous metastasis and size of tumor also, was not important. As a conclusion, MVD was increased in tumor and has shown correlation with metastasis, and vascular invasion. Resulting angiogenesis increase risk of metastasis.

Abstract
Background: Pulmonary involvement is a common and serious complication of rheumatoid arthritis. This cross sectional study sought to determine the prevalence of pulmonary disease in patients with rheumatoid arthritis on the basis of history, physical examination, chest X-ray and PFT.
Materials and Methods: 103 patients (81 Women, 22 Men) fulfilling the ACR (American College of Rheumatology) criteria for RA (Rheumatoid arthritis) were consecutively included in a cross sectional study. Detailed medical (including respiratory symptoms and the disease activity symptoms) and drug and occupational histories and smoking were obtained. All patients underwent a complete pulmonary and rheumatologic examination and conventional chest radiography. All patients underwent PFT that comprised spirometry and body plethysmography.Results for PFTs were expressed as percentage of predicted values for each individual adjusted for age, sex, and height.
Results: On the basis of history: Their mean age was 43.3 ± 2.6 years (range: 17-74) and the mean duration of the disease was 69.3 ± 15.6 months. Rheumatoid factor was positive in% 61.2. No patients were 0.5Pack/Year smoker in whole life. Prevalence of pulmonary involvement based on radiographic and pulmonary function test detected in 41 patients (39/7%). The most frequent respiratory clinical finding was dyspnea (33%), (NYHA grade I in 17.5% and NYHA grade II in 15.5%), Cough (with or without sputum) in 13.6 %, Crackle was the most sign in pulmonary examination (5.8%). Chest X-ray was abnormal in 13.3 % that the most common finding in this study was reticulonodular pattern in 20 patients (19.4 %), and pleural effusion detected in 7 patients (6.7%). PFT was abnormal in 30 patients (29.1 %). A significant decrease of FEF 25%-75% below 1.64 SD. Small airway involvements was the most abnormal finding of PFT. No relation between rheumatoid arthritis disease activity (ESR>30, Morning stiffness>30', Anemia, thrombocytosis) with pulmonary disease was seen.
Conclusion: This study suggests a high prevalence of lung involvement in patients with rheumatoid arthritis.Therefore we recommend a complete investigation in patients with RA with any respiratory symptom.

Abstract
Background: Exogenous natural and synthetic surfactants is a rescue treatment for respiratory distress syndrome (RDS). The goals of the study were to compare the clinical response and side-effects of two frequently used surfactants, poractant alfa (Curosurf) and beractant (Survanta), for the treatment of respiratory distress syndrome in preterm infants.
Methods: This clinical trial study was performed during a two-year period in the Neonatal Intensive Care Unit of Ghaem Hospital in Mashhad, Iran. Sample size calculated by a 95% confidence and power of 80, included 104 premature neonates, 74 in survanta and 30 in curosurf groups. The level of statistical significance was considered to be < 0.05.
Results: There were no statistically significant differences between the infants treated by survanta or cursurf groups regarding their mean gestational age (30.58 Vs. 29.00 weeks) and birth weight (1388 Vs. 1330 g), (p=0.3) There were also no significant differences between the two groups regarding incidences of broncho- pulmonary dysplasia (BPD) (40.5% Vs. 40%), intraventricular hemorrhage (IVH) grades III/IV (13.5% Vs. 13.3%), pneumothorax (both 20%), patent ductus arteriosus (PDA) (28/3% Vs. 20%) or death (28% Vs. 26.6%) on the 28th day postpartum.
Conclusion: This study showed that survanta and curosurf had similar therapeutic effects in the treatment of neonatal respiratory distress syndrome.

Abstract
Background: ATP-binding cassette transporter A1 (ABCA1) is a key mediator of
cholesterol efflux to apoA-I in lipid-laden macrophages, the first step of reverse cholesterol transport (RCT) in vivo and a critical step in preventing atherosclerosis.
Enhanced ABCA1 expression may inhibit foam cell formation and consequently reduce atherogenic risk. On the other hand, garlic, Allium sativum, and garlic extracts have been demonstrated to have potential cardiovascular benefits. Moreover, garlic has direct antiatherogenic and antiathersclerotic effects on artery walls. The aim of this study was to evaluate the effects of alcoholic garlic extract on the expression of ABCA1
in macrophages.
Methods: Cell viability assay was used in order to detect the cytotoxic dose of alcoholic garlic extract on macrophages. Real-time PCR and Western blotting were performed to study the effects of alcoholic garlic extract on the expression of ABCA1. Macrophage cells were treated by different concentrations of alcoholic garlic extract for 48 h. The total RNA of the treated macrophages were extracted and analyzed by real-time PCR. ABCA1 protein expression was also analyzed using the Western blotting technique.
Results: Alcoholic garlic extract increased the ABCA1 mRNA (20-23%) and protein expression (18-37%) in THP-1 macrophage cells compared with the controls (untreated cells).
Conclusion: The results of this study are suggestive of the potential effects of alcoholic garlic extract in increasing ABCA1 expression in macrophages, the possibility of promoting reverse cholesterol efflux in macrophages and preventing atherosclerosis

Abstract
Background: Cell-therapy provides a promising alternative for the treatment of type 1 diabetes. Monocytes which have a reprogramming or differentiation potential and are more available than any other types of stem cells, have been recognized as candidates for such investigations. The aim of the present study was to evaluate the differentiation potential of rat peripheral blood monocytes into insulin-producing cells by the use of rat pancreatic extract (2 days after a 60% pancreatectomy).
Methods: Rat peripheral blood monocytes were isolated and cultured. Adherent monocytes were induced to differentiate into programmable cells in RPMI supplemented by 10% FCS, &beta-mercaptoetanol, M-CSF and IL-3 for six days. The dedifferentiated cells were analyzed by invert microscopy. Cultures of Programmable Cells of Monocytic Origin (PCMOs) were continued in RPMI, containing 10% FBS, pancreatic extract and 5 mmol/L glucose for 15 days. The medium was replaced every three days. At the end of the protocol, insulin and c-peptide excreted by the differentiated cells were tested by radioimmunoassay on days 6, 14, and 21. In order to verify insulin production in the cells, dithizone-staining, which is a method for insulin identification, was employed.
Results: The results showed that the cells cultured in rat pancreatic extract secreted insulin and c-peptide relative to the control group. Dithizone-staining was positive in the aforesaid cells (P<0/05).
Conclusion: The results of the current study showed that pancreatic extract treatment can differentiate rat peripheral blood monocytes into insulin-producing cells which can be regarded as a potential source for the treatment of diabetes.

Background: Too many studies are in the process
of determining the probable role of immune system in the etiopathogenesis of
nasal polyposis. This study was designed to identify the probable participation
of Th1, Th2 lymphocytes in the induction and progression
of nasal polyposis.
Methods: Seventy-five patients, 42 male and 33 female, with
nasal polyposis were examined for total serum IgE, specific serum IgE and reaction to skin test for differentiating allergic from
non-allergic participants in Rasoul Akram Hospital during 2010. To determine the possible correlation of allergic
reactions in the upper respiratory tract and nasal polyposis, cytokine gene
expression was evaluated on the extracted RNA by
RT-PCR. The data were analyzed by using c2, independent t-test, correlation and
Receiver operating characteristic (ROC)
curve.
Results: The mean
age of participants was 38 years (18-81 years). IFN-γ
and IL-4 gene expressions were more prevalent
in allergic than non-allergic individuals (IFN-γ:
39.5% vs. 14.2%, P=0.3 and IL-4: 44.7% vs. 18.9%, P=0.02, respectively). IL-10 and IL-12 (P35 and P40 fractions) genes were not
significantly different between the two groups. IL-10 and IL-12 (P35, P40) genes did not differ significantly either.
Conclusion: This research suggests that overproduction of
cytokines and an imbalance of Th1
and Th2 cell production may
play an important role in the pathophysiology of allergic or non-allergic nasal
polyp formation. Thus, although nasal polyposis is a multifactorial disease
with several different etiological factors, chronic persistent inflammation is
undoubtedly a major factor irrespective of the etiology.

Abstract
Background: The characteristic of stem cells in self renewal and differentiation to different types of cells has stimulated the interests for using stem cells as a starting material for generating insulin secreting cells. We've evaluated the differentiation potential of Programmable cells of monocytic origin (PCMOs) into insulin producing cells effected from the growth factors and fibroblasts conditioned media (FCM).
Methods: Peripheral blood monocytes of rat were cultured for 6 days in RPMI with 15% FBS, β- mercaptoethanol, MCSF and interleukin-3. Then, these cells were incubated in differentiation media with HGF, EGF, Nicotinamide, 15% fibroblasts conditioned media and glucose for 15days. Morphological differences of cells were studied by invert microscope. In several stages, the amounts of insulin in supernatant of cells were measured by radioimmunoassay kit. Also productions of insulin from differentiated cells were studied with DTZ special staining.
Results: In response to MCSF and IL-3, monocytes dedifferentiated. These programmable cells of monocytic origin (PCMOs) were capable of differentiating into insulin producing cells in differentiation media. The morphology of differentiated cells was similar to Beta cells and the amount of insulin in supernatant of differentiated cells was much higher than PCMOs (P<0.05).
Conclusion: HGF, EGF, Nicotinamide and fibroblasts conditioned media are differentiation factors of PCMOs into insulin producing cells. According to the results insulin producing cells can be differentiated from programmable cells of monocytic origin in presence of fibroblasts conditioned media.

Abstract
Background: Ischemia/reperfusion induced acute renal failure causes excretory functional disorders of nephrons. Ischemia/reperfusion injury is accompanied by generation of reactive oxygen species that leads to dysfunction, injury, and death of renal cells. Antioxidants of plant origin minimize the harmful effects of reactive oxygen species. The aim of this study was to determine the possible therapeutic potentials of Rosa canina L. in preventing renal functional disturbances during the post-ischemic reperfusion period.
Methods: In this experimental study undertaken for evaluating renal excretory function in 30 male Wistar rats, renal ischemia was induced by occluding both renal arteries for 45 min, followed by 24 h of reperfusion. The rats received 2 ml of tap water or a hydroalcoholic extract of Rosa canina (500 mg/kg) orally for 7 days before induction of ischemia. In plasma samples, creatinine and urea nitrogen levels were measured, and in renal tissue samples, red blood cells were counted. The data were analyzed using ANOVA and Duncan tests.
Results: Renal ischemia for 45 minutes increased plasma levels of creatinine (P<0.001) and nitrogen urea (P<0.01) while reducing red blood cell counts in renal glomeruli (P<0.001). Rosa canina administration diminished the increase in creatinine (P<0.001) and nitrogen urea concentrations (P<0.01), and prevented reductions in red blood cell counts in renal glomeruli (P<0.001).
Conclusion: Rosa canina seems to be useful as a preventive agent against renal damages induced by ischemia/reperfusion injuries in rats.

Abstract
Background: Staphylococcus aureus secretes numerous superantigenes which trigger the inflammatory mechanisms of sinus mucosa and cause chronic rhino-sinusitis. This study was designed to evaluate the role of staphylococcus aureus superantigens in polyp tissues of patients with chronic rhino-sinusitis in comparison with a control group.
Methods: Polyp tissue samples of 28 patients and mucosal specimens of 19 healthy individuals were evaluated for staphylococcus aureus bacterium superantigens, exotoxins A, B, C and D and TSST-1 with RT-PCR and ELISA methods Rasoul Akram Hospital during 2 years.
Results: Polymerase chain reaction (PCR) results revealed that 88.2% of the patients and 45.5% of the controls had at least one type of superantigen (P=0.03). Evaluation of superantigens using ELISA method showed presence of at least one type of superantigen in the nasal samples of all patients and in 35.3% of the controls (P<0.001).
Conclusion: A relationship between staphylococcal superantigens and nasal polyps is concluded from this study which indicates the probable role of these superantigens in the pathogenesis of nasal polyposis.

Abstract
Background: Tonsils and adenoid hypertrophy is a major respiratory symptom in children which is partly due to recruitment of inflammatory cells in upper airway lymph nodes as a result of the effects of synthesis and release of different inflammatory cytokines. It seems that infections play role in concert with these cytokines leading to tonsilar hypertrophy and other pathologic consequences. It is proposed that cellular infiltrate of tonsils and adenoids may secrete different quantities of these cytokines compared with peripheral blood mononuclear cells (PBMC) cultures.
Methods: Among patients who were admitted for adenotonsillectomy to the ENT ward, 37 patients, under 1-12 years old patients with fulfill criteria selected to include the study. Excised adenoid and tonsils cultured and inflammatory cytokines Interferon-γ (INF-γ), Interlukine-1 (IL-1), IL-6, IL-8 and tumor necrosis factor-α (TNF-α) measured in cellular culture supernatant. The same cytokines measured in PBMC cultures.
Results: The data shows that there is a significant difference between IFN-γ and IL-8 amounts in adenoid tissue culture supernatant and PBMC culture of our patients. Furth-ermore, the amounts of IFN-γ, IL-1 and IL-8 showed considerable difference between tonsilar tissue culture supernatant and PBMC culture of these patients. Although there is a significant correlation between IL-6 amounts in tissue culture supernatant and PBMC culture (P=0.02), the respective data for TNF is only almost significant.
Conclusion: Inflammatory cytokines may have significant role in the early provoke of inflammation occurred in hypertrophied tonsils and adenoid. The majority of these cyt-okines increase the expression of adhesion molecules on epithelial cells and influence the recruitment of leucocytes and inflamed tonsils. On the other hand lack of sufficient cytokine release may lead to persistent infections and may cause chronic inflammation and hypertrophied tissue.

Abstract
Background: Urinary tract infection (UTI) is one of the most common infections in infants and children, especially in their first decade of life. These patients are more susceptible to renal scars and other possible complications like growth retardation, arterial hypertension, proteinuria, isostenuria, and finally chronic renal failure. Trace elements like vitamins and minerals are essential for efficient metabolism and proper function of various body systems namely immune system. In this trial we compared the relation between serum levels of zinc, vitamins A and D in children inflicted with UTI and control group.
Methods: This was a cross-sectional study on 25 patients with UTI admitted to pediatric wards of Rasul Akram Hospital and Bahrami Hospital. They were compared to 40 other patients admitted in surgical wards for elective surgery. Serum levels of zinc, vitamins A and D were measured in both groups.
Results: Seventy two percent of the patients were male and 28% female. The average age was 2.17. Despite the lower levels of vitamins A and D in cases than controls, the difference was not significant (P=0.4 and P=0.9, respectively). However, serum levels of zinc were significantly lower in cases than controls (P<0.05).
Conclusion: Vitamins A and D may play some role in patients’ vulnerability to UTI, but this supposition needs more research on larger samples, considering differences among patients of various age groups and their nutritional status.
According to the study, lower levels of zinc were associated with susceptibility to UTI thence, its administration might be helpful.

Abstract
Background: Nasal polyp (NP) is a benign mucosal mass located in both sinuses and nares which is mostly seen in association with cystic fibrosis, asthma or oversensitivity to aspirin. The prominent histological feature of NP is inflammatory cell infiltration with eosinophil predominance. Superantigens role in causing NP complications is already proven. Superantigens, which are mostly originated from Streptococci and Staphylococci, activate T cells strongly and increase the process of production and release of cytokines, and secretion of IgE from B cells, which in turn directly affects proinflammatory cells such as eosinophils, both in their tissues infiltration and functions.
Methods: The samples are collected from patients referring to ENT clinic in Rasoul Akram training Hospital in Tehran after thorough clinical and paraclinical examinations. For control group the samples collected from patients undergoing rhinoplasty. All the samples kept frozen and sent to immunology lab. The DNA of the excised tissues extracted and amplified by using the superantigens specific primers and PCR product detected by gel electrophoresis. The date analyzed by using mean and SD and χ2 analytical tools.
Results: Fifteen healthy individuals, 25 patients with rhinosinusitis and 24 with polyposis entered this trial. Group A Streptococcus toxin detection was significantly more frequent in those with nasal polyp and rhinosinusitis compared to healthy individuals (P=0.001 and 0.005, respectively), but the results were almost the same for those with nasal polyp and rhinosinusitis (P=0.4).
Conclusion: Streptococci may play an important role in induction or clinical exacerbation of polyposis and group A Streptococcus pyogenes exotoxin (SPEs) with superantigenic effects may have a crucial role in etiology and pathogenesis of polyps with or without rhinosinusitis. It is postulated that, T cells polyclonal activation by SPEs may cause recruitment of inflammatory cells in nasal mucosa. These inflammatory cells include IgE producing B cells laeding to allergic and inflammatory reactions in NP.

Abstract
Background: Meningitis is one of the serious and dangerous infections in the infancy and childhood and rapid diagnosis of meningococcal disease is important, especially in infants. C-reactive protein (CRP) is a protein found in blood and is an acute phase protein. CRP sensitive reactive that used for diagnosis of infection. This study conducted to assessment of the relationship between cerebrospinal fluid C-reactive protein, and neonatal meningitis, as well as diagnostic value of test.
Methods: Forty nine hospitalized infant that suspected to meningitis were enrolled in this analytic cross sectional research via non probable accessible sampling. 28 patients (52.7%) of all the patients were male and 21 patients (42.8%) were female. The average age of the patients was 22.6±11.88 days. Data from clinical examinations and laboratory tests entered in a questionnaire and all of samples divided in two bacterial (septic) and non-bactria (aseptic) meningitis group. All data including cerebrospinal fluid CRP of newborns were statistically analyzed.
Results: In total, the mean and standard deviation of age was 22.6±11.88 days. 57.2% of infants were male and 42.8% were female. In total, 40.82% of infants were diagnosed with septic meningitis. There was no significant difference between septic and aseptic groups in terms of sex (P= 1.00) also in terms of age (P= 0.1). The mean and standard deviation of CRP level in septic meningitis group was 0.95±0.68 mg/L and in aseptic group was 0.16±0.36 mg/L. The CRP level difference in septic meningitis group compare with aseptic group was statistically significant (P<0.000). The finding showed that cut off point for CRP level as a diagnostic test was 0.17 mg/L, sensitivity was 95% and specificity was 86%.
Conclusion: In the present study, newborns with septic meningitis had higher cerebrospinal fluid CRP level than newborns with aseptic meningitis, and CSF-CRP can be used in rapid diagnosis of septic and aseptic meningitis. Although this result has been seen in many studies, but more research is needed.
