Abstract
Zinc has an important role in skin health and its deficiency reduces immunity. To evaluate levels of Zinc in squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) of skin, we studied 44 BCC and 38 SCC cases together with 33 controls. Blood samples were taken and after separation of serum, levels of Zinc, albumin and total protein were measured by atomic absorption, albumin kit and reflectometer consecutively. Serum globulin levels were stimated by substracting albumin from total protein levels. Zinc levels were significantly lower in cancer cases than control (P<0.001). Mean serum albumin of BCC cases was significantly more than controls (P<0.01), but in BCC cases was not significantly different. Significant correlations were seen between levels of serum Zinc and albumin of SCC (R=0.507, P<0.01) and BCC (R=0.43, P<0.01) patients and controls (R=0.35, P<0.01). Mean globulin levels in cancer cases were significantly lower than control group (P<0.01). We concluded that serum Zinc and globulin levels decrease in BCC and SCC of skin.

Abstract
Background: The important of angiogenesis for the progressive growth and viability of solid tumors is well established. Only few data are available for hematologic neoplasms.
Materials and Methods: To investigate the role of angiogenesis in the acute myloid leukemia (AML) bone marrow biopsies from 30 adults with newly diagnosed, untreated AML(day 0) were evaluated. Further studies were done after completion on remission induction of treatment (day 35 of 7×3 regimen n=13, complete remission in AML (m3) treat with arsenic trioxide n=17). Micro-vessels were scored in at least 3 areas of highest micro-vessel density in representative section of each bone marrow specimen using immunohistochemistry for Von Willbrand factor.
Results: Median micro-vascular density (MVD) were in AMLM3 patients before treatment, %6.81±3.58 and after treatetment %3.48±3.06 (p<0.0001). In other AML patients MVD were befor treatment %3.38 and after treatment %3.6.
Conclusion: In conclusion, there is evidence of increased micro-vessel density in the bone marrow of patients with AML, which supports the hypothesis of an important role of angiogenesis in AML. MVD was reduced with chemotherapy and arsenic. Furthermore , these finding suggest that antiangiogenesis therapy might constitute a novel strategy for the treatment of AML.

Abstract
Background: The aim of this study was to evaluate the association between atypical glandular cell (AGC) on Pap smear and significant pathologic finding to tailor management protocols.
Methods: Between 2002 and 2005, Among 26893 Pap smears 122 women with AGC Pap smears (prevalence=0.45%) were referred to our colposcopy clinic. Forty one women underwent colposcopy directed biopsy, endocervical curettage, endometrial sampling and cervical conization to determine the cytologic and histologic correlations of AGC on pap smears.
Results: A total of 122 women with AGC Pap smear were found. Only 41 women accepted to participate in the study and followed the workup procedures. The mean age of the patients was 46.92 ±11.48 years (range, 23-80 years). Of these patients 13 patients (31.7%) were post menopause and 28 patients (68.2%) were in reproductive age.
We found 13 (31.7%) significant pathologic findings including 4 (9.7%) high grade squamous intraepithelial lesion (HG-SIL), 3(7.3%) low grade squamous intraepithelial lesion (LG-SIL), 2(4.8%) Endometrial hyperplasia, 1(2.4%) Endometrial adenocarci-noma, 1(2.4%) adenocarcinoma of cervix, 1(2.4%) squamous cell carcinoma of cervix and 1(2.4%) papillary serous tumor of ovary. There was not any significant difference in the prevalence of significant pathologic findings and subtype of squamous or adenomatous lesions between pre and postmenopausal group.
Conclusion: AGC on Pap smear was associated with a clinically significant diagnosis in approximately one third of our cases. The women with a diagnosis of AGC on cervicovaginal smear are needed to be evaluated at least with colposcopy, endocervical and endometrial curettage. Clinicians should be careful about the significance of AGC in pap smears.

Abstract
Background: Bone marrow transplantation (BMT) is the treatment of choice for many patients with malignant and nonmalignant diseases. Long-term complications such as osteoporosis should be considered, because it is directly associated with the morbidity and mortality. The purpose of this study is to assess the bone mineral density after allogenic or autologous bone marrow transplantation in patients with leukemia or lymphoma.
Methods: We prospectively investigated 63 patients undergoing BMT for acute and chronic leukemia and lymphoma. At the end of the study, a total of 28 patients were assessed. Bone mineral density (BMD) was measured prior BMT, and 6 and 12 months after BMT. Osteocalcin, bone alkaline phosphatase and C-terminal telopeptides of type 1 collagen (ICTP) were assessed. Serum concentration of calcium, phosphorous, vitamin D, PTH and sex hormones (FSH, LH, testosterone and estradiol) were also measured.
Results: There was a significant decrease in the bone mineral density of the femoral neck six months after BMT (p<0.001), 1.01±0.13g/cm² prior to BMT and 0.96±0.13 g/cm² at six months, but no considerable changes were seen in lumbar vertebrae. Bone loss between the 6th and 12th months was not observed. The levels of ICTP and phosphorus increased significantly by the 12th month (p=0.04). The level of calcium was higher at the 6th month (p=0.002) but the level of vitamin D and PTH decreased by the end of the study (p=0.04 and p=0.01, respectively) and the average of osteocalcin did not increase significantly. In women, the level of estradiol decreased by the 6th month (p=0.01), but the testosterone changes were not significant.
Conclusion: The risk of bone loss in both allogeneic and autologous BMT is higher in the femoral neck than the lumbar vertebrae, occurring mainly in the first six months after BMT. Preventive and clinical procedures should be considered.

Abstract
Background: The knee is the most commonly injured joint. The internal components of the knee include the meniscuses, the anterior cruciate ligament (ACL) and posterior cruciate ligaments (PCL). Magnetic resonance imaging (MRI) is now used widely because of its high accuracy and noninvasiveness. Our objective was to diagnose internal knee component injuries by MRI and compare its diagnostic value with that of arthroscopic surgery.
Methods: This process research study was carried out between May 2004 and September 2006 on 90 randomly selected patients admitted to the orthopedic ward of Baghiatollah Hospital, Tehran, Iran. Each patient had arthroscopic surgery after undergoing MRI by an expert radiologist.
Results: Out of 90 patients, 81 were male and nine were female. The mean age was 31.6 years (range: 17-71). Among patients with normal ACL as shown by MRI, 42.4% were shown by arthroscopy to have a ruptured ACL. The sensitivity and specificity of MRI in ACL abnormalities were 73% and 77%, respectively. Only 1.3% of the patients with normal PCL by MRI showed PCL rupture upon arthroscopic examination. The evaluation of the lateral meniscus by MRI had a sensitivity and specificity of 40% and 94%, respectively. Likewise, in the medial meniscus, sensitivity and specificity by MRI was 70% and 98%, respectively.
Conclusion: According to our study, considerable differences exist between MRI reports and arthroscopic findings in the diagnosis of internal knee injuries. We therefore conclude that sole reliance on MRI reports is not reasonable for making treatment decisions and MRI should be used as just one of the diagnostic tools, in conjunction with other methods, such as physical examination and arthroscopy.

Abstract
Background: Aspirin is the drug of the century, and is a multifunctional drug and one of the most prescribed drugs in the world. Aspirin is a safe drug at low doses but also it has life-threatening side effects when administered at high doses. This study investi-gates the effects of aspirin on renal cortical and medullary tissue in rat embryos.
Methods: In this study, 30 pregnant female rats were randomly divided into 6 groups. Control group with no intervention, sham group received 2 ml distilled water (as a sol-vent of aspirin) received from days 8 to 20 of pregnancy, and four experimental groups received different doses of 75, 100, 200 and 300 mg/kg of aspirin by gavage. Pregnant rats were sacrificed on the twenty days of pregnancy and the fetuses were removed. Weight of the fetuses and placenta and Crown-Rump length were measured. Fetal kid-neys were fixed in formalin processed, sectioned and stained with Hematoxylin- Eosin. Thickness of renal cortical and medullary tissue by using a Motic hardware and soft-ware system were measured and recorded. A significance level of 0.05 was predeter-mined for all statistical analyses.
Results: No apparent fetal anomalies were observed in experimental groups. In addi-tion, no significant differences were shown in the mean of fetal weight, placental weight, mean of Crown-Rump length in experimental groups 75, 200 and 300 mg/kg compared to control and sham groups. Mean fetal and placental weight in experimental group 100 significantly increased compared to control and sham groups. Mean ratio of renal cortex to renal medulla in experimental group 75, 100 and 300 were significantly decreased compared to control and sham groups (respectively P= 0.03, P= 0.013, P= 0.03).
Conclusion: It seems that maternal use of aspirin during pregnancy can not cause fetal abnormalities. However, it can cause some changes in renal cortical and medullary tis-sue of rat embryos.

Abstract
Angiogenesis, as the process of new vessel formation from pre-existing vessels is dependent on a delicate equilibrium between endogenous angiogenic and antiangiogenic factors. However, under pathological conditions, this tight regulation becomes lost which can result in the formation of the different diseases such as cancer. Angiogenesis is a complex process that includes many gene products that are produced by different cells. Each of the processes influenced by specific genes that their expression can be regulated by hypoxi inducible factor-1 (HIF-1). Hypoxia, the imbalance between the oxygen in need and the oxygen available, usually occurs in tumors and ischemic cardiovascular diseases. In order to overcome this challenge, tumors regulate and control the expression of genes related to angiogenesis, cell cycle and metabolism using hypoxia-inducible factor 1 (HIF-1). HIF-1 was first recognized as a transcription factor involved in hypoxia-induced erythropoietin expression. As angiogenesis pathway molecules are being described, this factor has been characterized as a key transcription regulator for these molecules. In this review article, after discussing HIF-1 structure and characterization, the role of this important factor in angiogenesis and cancer as a pathological case and finally, the clinical applications has been evaluated. Articles related to the key words of hypoxia, HIF-1 and angiogenesis were searched from valid databases such as Springer Link, google scholar, Pubmed and Sciencedirect. Then, the articles related to the role of hypoxia and HIF-1 in activation of genes that are involved in angiogenesis and cancer were searched and selected for this study. Studies show that, HIF-1 activation of genes including vascular endothelial growth factor (VEGF), angiopoietin-1 (Ang-1) and angiopoietin-2 (Ang-2), etc., induced angiogenesis in the tumor cells. Furthermore, the activation of genes such as insulin-like growth factor 2 (IGF2), transforming growth factor α (TGF-α) and MAPK and PI3K signaling pathway will also enable the survival and proliferation of tumor cells. HIF-1 by activating genes involved in angiogenesis and also activates signaling pathways associated with cell survival and proliferation plays an important role in the stability and growth of tumors. Therefore, better understanding of molecular mechanisms associated with this factor can be effective in the treatment of cancer.

Abstract
Background: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive age women. The prevalence of PCOS among Iranian women is 14.6% based on the Rotterdam definition. PCOS can increase the risk of chronic metabolic complications. Metabolic syndrome (MetS) is one of the most important of them. Insulin resistance is fundamental in PCOS and MetS pathophysiology. MetS is a collection of chronic metabolic derangements, which promotes the risk of serious diseases such as cardiovascular disturbances and diabetes. The quality of diet is inversely correlated with obesity, which is one of the consequences of PCOS and it is a risk factor for metabolic syndrome. As the first study, the present study aimed to compare the dietary intake of macronutrients in PCOS women with and without MetS.
Methods: In this nested case-control study, the convenience sampling method was used to select participants. The case group included 14 PCOS patients with MetS and the control group included 28 PCOS patients without MetS. The investigated macronutrients included fats (total fat, saturated fatty acids, mono and polyunsaturated fats, trans fatty acids), carbohydrate, protein, and fibers (total and soluble). The dietary intake assessment was carried out by a 168-item semi-quantitative food frequency questionnaire (FFQ). This study was performed on Arash Women's Hospital under support of Tarbiat Modares University, Tehran, Iran, from August 2014 to September 2015.
Results: Dietary intake of total fat was significantly higher in PCOS women with MetS than the control group (P<0.001, 146.62±45.17 vs. 59.91±32.79 g/d). Dietary intake of saturated fatty acids (P=0.004, 11.44±11.08 vs. 19.73±6.76 g/d), monounsaturated fats (P<0.001, 14.15±12.66 vs. 26.16±7.76 g/d), polyunsaturated fats (P=0.002, 9.02±9.18 vs. 17.22±6.45 g/d), carbohydrate (P<0.001, 182.34±121.08 vs. 365.64±77.11 g/d), protein (P=0.001, 42.74±42.85 vs. 78.06±24.04 g/d), total fiber (P<0.001, 17.77±15.09 vs. 35.97±22.64 g/d) was significantly lower in PCOS women with MetS than the control group. All results are expressed in terms of grams consumed per day.
Conclusion: Our results demonstrated that dietary intake of macronutrients was significantly different in polycystic ovary syndrome patients with and without metabolic syndrome.

Abstract
Background: Cancer is the third leading cause of death in Iran. Cancer treatment is very costly and chemotherapy drugs are one of the main causes of the high cost of cancer treatment. The purpose of this study was to evaluate the cost of chemotherapy drugs of five most common cancers and identifying the factors might affect the costs of chemotherapy drugs in a one of the large provinces of Iran, located in the center of the country.
Methods: In a cross-sectional study, the data of all patients with five common cancer diagnosed from March 2015 to March 2016 in Isfahan Province in Iran were collected from the Cancer Registry Center of Isfahan, as well as the pharmacies which distribute chemotherapy drugs. The required information (including, patient characteristics, type of cancer, and the costs of chemotherapy) of patients was obtained by linking the information of patients registered in the distributor pharmacies with the patients registered at the Isfahan Cancer Registry Center through the national code of the patients.
|
Results: Breast, skin, colorectal, stomach and thyroid cancers were the most common cancers within the evaluated period of time in Isfahan Province. Colorectal cancer with an annual average total cost of 110,510,720 IRR (Rials) per patient was the most expensive cancer during the evaluated time period while thyroid cancer with an annual average total cost of 40,791,123 IRR per patient was the least costly cancer within the evaluated time period in Isfahan among the five most common cancers, considering the chemotherapy medicines cost. The highest cost in the colorectal cancer was due to the drug cetuximab distributed under the trade name Erbitux®. Regardless of the cancer type, the mean annual total cost of chemotherapy drugs per patient within the considered period of time calculated to be 96,307,145 IRR.
Conclusion: The chemotherapy cost of the common cancers was high with an annual average of more than 96 million IRR (Rials) per patient, within the considered time period. This was particularly true for colorectal cancer with an annual average cost of more than 110 million Rials. |

Abstract
Background: Common treatment for infertile couples is the use of controlled ovulation hyperstimulation (COH) with intrauterine inseminations (IUI). IUI is used in cases such as ovulatory dysfunction, cervical factor infertility, male subfertility, and unexplained infertility. In this study, we evaluated the relationship between IUI outcome and special causes of infertility.
Methods: This was a cross-sectional study and a sampling method was available in this study, from January 2014 to August 2016, 994 cycles in 803 infertile couples referred to Royan Research Institute in Tehran were analyzed. Inclusion criteria were: male factor infertility, combined causes, ovarian disease, and infertility of unknown cause. To evaluate pregnancy, 12-16 days after IUI, it was considered positive if pregnancy test followed by transvaginal ultrasound at week 4 after IUI were positive.
Data were analyzed using SPSS software, version 20. T-test and chi-square were used to compare the case and control groups. Linear-by-linear test was also used to calculate the relationship between female age and clinical and multiple success rates. P<0.05 was considered significant for the results of these tests.
|
Results: The success rate of pregnancy in all cycles (16.5%) and live birth rate per cycle (14.5%) were calculated. The mean age in the pregnant group was significantly lower than that of the non-pregnant group (P = 0.01). Our findings were: Infertility with unknown cause (290 people, 29.2%), male factor (395 people, 39.7%), ovulation disorders (201 people, 20.2%) [which include: decreased ovarian reserve (1 person) 0.5%), polycystic ovary syndrome (188 patients, 93.5%) and hypothalamic amenorrhea (12 patients, 6%)] and a combination of different factors (108 patients, 10.9%). There was also a significant relationship between the cause of infertility and clinical pregnancies (P<0.001). A Significant decrease in pregnancy success rate was observed with increasing infertility duration (OR=0.8, CI=0.8-0.9, P<0.001).
Conclusion: Women’s age, etiology of infertility, duration of infertility, irregular menstruation, semen volume, and gonadotropin dose were important factors in COH+IUI cycles.

Abstract
Background: Assisted reproductive techniques have increased the chances of pregnancy for couples looking for a way to treat their infertility. To increase the effectiveness of these methods, studies are needed to identify the determinants of a successful pregnancy with these techniques.
Methods: The present study is a cross-sectional retrospective study that was performed on 253 couples who were referred for infertility treatment to the infertility clinic of Shahid Beheshti Hospital in Isfahan from April 2019 to March 2020 to evaluate the results of pregnancy in vitro fertilization. Demographic, clinical, and laboratory data from patient records were collected and entered into checklists.
|
Results: Out of 253 couples, eighty-five (33.6%) became pregnant by IVF. The mean age of women with successful pregnancies was 33.96±5.2 years and in the unsuccessful pregnancies was 35.84±5.07 years. The results of this study showed that women who had a successful pregnancy after IVF were significantly younger than women who did not have a successful pregnancy (P=0.006). In the classification of patients into two groups of positive and negative pregnancies, younger age, adequate vitamin D levels, and higher sperm motility were the determinants of pregnancy in the first period of fertilization (Fresh protocol). Also, the existence of a failed history of infertility treatment in couples has been introduced as a negative factor for IVF fertility. 13(15.9%) abortions occurred and 11(12.9%) infants who were born with this method needed intensive care.
Conclusion: Lower age at the time of fertilization, higher vitamin D levels, and more active sperms were found to have important and prognostic roles in the success of pregnancy by in vitro fertilization technique.
The results of the present study showed that, Increased unsuccessful treatment has been associated with the history of failed treatment. Therefore, to respond to the relationship between previous infertility treatments and success in subsequent pregnancies in the IVF process, It is recommended to conduct studies with larger sample size and at a higher time efficiency.

Abstract
Background: The rate of exclusive breastfeeding in Iran at the ages of 3 and 6 months is estimated to be 44% and 27%, respectively, which is still far from the optimal index of the World Health Organization until 2030 (70% in the first six months). In order to monitor breastfeeding counseling centers, which have been set up with the aim of promoting breastfeeding and supporting mothers who have problems with breastfeeding.
Methods: This is a descriptive-retrospective study and all the mothers who were referred to the Health and Treatment Center No. 2 in Mashhad between April 2019 and March 2019 were examined. This health center has two active counseling clinics and the collection of information is based on documents registered in offices and computers. The inclusion criteria for study were not having breast diseases, having an infant child, being able to read and write and living in Mashhad city. The exclusion criteria were also the unwillingness to participate in the study and the newborn suffering from diseases that are incompatible with breastfeeding. Therefore, census sampling was done. The data were analyzed using SPSS 16 software and the significance level was less than 0.05.
|
Results: In 42.8% of cases, mothers had started feeding combined formula with breast milk before visiting, and in 28.1% of cases, when referring to counseling milk clinics, it was reported that the baby was fed only with formula. After breastfeeding consultations and follow-ups at the end of six months, the rate of exclusive breastfeeding is 34.1% (12% increase compared to the initial reference) and combined formula feeding with breastmilk is 27.8% (a 22% decrease compared to the first visit). And feeding with powdered milk alone was calculated to be 36.5% (an increase of 8.4% compared to the first visit).
Conclusion: The positive role of breastfeeding counseling center in reducing the cases of artificial feeding is clear, and it is recommended to prepare written instructions based on the challenges in breastfeeding for breastfeeding counseling in the first month after delivery.
