Abstract
Background and Aim: Anemia is one of the common problems in patients with chronic renal impairment. The most common cause of anemia in this patients is a decreased in erythropoietin hormone excretion, however other common cause include low life of red blood cells, loss of blood during dialysis, frequent blood sampling, uremia, iron, vitamin B12 and folic acid deficiency. Until introduction of erythropoietin in 1982, blood transfusion was an alternative for correction and maintaining hematocrit in normal range in dialyze patients. In current date, any dialyzed patient take rh-erythropoietin .
Materials and Methods: The goal of this study is to evaluate erythropoietin utilization and comparing the effectiveness of the commercial product in the Iranian drugs market. The study was performed at nephrology and dialyze ward of Immam Khomeini hospital in a one year period.
Results and Conclusion: Of the 30 patients&apos subject of study, 13 patients received eprex and 17 received epocim. Average dose of erythropoietin 2000IU was three times per week. The average plasma hemoglobin and hematocrit of patients prior to the treatment were 9.38 g/dl and 28% respectively. Increase in the hemoglobin and hematocrit in the group who received eprex was significantly higher than epocim group (p=0.001 and p=0.026 respectively). The incidents of side effects including hypertension, headache, pain at injection site, and influenza-like in eposim group were considerably higher than eprex.

Abstract
Background: TPS is one of the tumor markers which has specially been considered due to its exclusive physiological characteristics like its easy measurement in serum of cancer patients. This study has been due to evaluate the efficiency of this tumor marker in the prognosis, treatment control and follow up of patients with gastrointestinal cancers including esophagus, stomach and colorectal.
Methods: TPS has been measured in 109 persons including 28 healthy people and 81 patients with different gastrointestinal malignancies which were composed of 38 patients with esophageal cancer, 20 ones with stomach cancer and 23 ones with colorectal cancer. Sampling has been done in three times depending on treatment methods. TPS has been measured with ELISA in samples which contend of 2 to 3 ml of serum from patients and the health.
Results: The obtained results, demonstrate the obvious changes in TPS serum level in patients underwent various treatment procedures.
Conclusion: The results have revealed that the serum TPS is not only as a measure of prognosis but also would be helpful in follow up and treatment control of the disease. Moreover the results has shown that serological analysis can be settled in the diagnosis and follow up with production of polyclonal antibody against TPS gene family and planning appropriate pattern.

Abstract
Background: Creutzfeldt-Jakob disease (C-JD) is a rare disorder characterized with rapidly progressive mental decline, myoclonic jerk and finally death. The transmissible pathogen for this disease is a proteinaceous infectious particle termed prion. The prion protein is encoded by a gene (designated as PRNP) on the short arm chromosome 20.This disorder is diagnosed based on clinical findings, course of disease, EEG, MRI and confirmed with brain biopsy.
Case report: A 56- year- old woman presented with confusion, disorientation, hyper somnolence, psychiatric problems such as hallucination, progressive mental deterioration and myoclonic jerks. She had history of several times phlebotomy with traditional and non sterile methods in two past years. She had no past history of other disease. Her illness was diagnosed based on clinical findings, course of her illness, typical MRI, EEG and rule out other dementing disease. She died after one month.
Conclusion: in any patients with psychiatric disorders, rapidly progressive mental deterioration and myoclonic jerks C-JD should be considered as an important diagnosis. Treatable dementing disease should be considered and ruled out at first. The significance of phlebotomy in C-JD has yet to be determined.

Abstract
Background: Scaphoid non::::union:::: remains a challenging problem for hand surgeons. In this study, we assessed the functional outcome of scaphoid non::::union:::: treatment and the influence of a number of variables on it.
Methods: In this study we recruited 24 patients with scaphiod non::::union:::: by consecutive sampling at Dr. Ali Shariati Teaching Hospital, in Tehran, Iran in 2008-2011. We examined the patients by antero-posterior (AP) and lateral view radiographies and wrist MRIs. Functional outcome of surgery was scaled according to Mayo wrist and Quick DASH scoring systems.
Results: Among 10 cases with osteonecrosis, there were 7 (70%) cases of radiological ::::union::::. In 13 (92%) out of 14 cases who had no signs of osteonecrosis, we radiologically confirmed scaphoid ::::union:::: after the treatment. The total ::::union:::: rate was estimated to be 83% at the end of 24 months follow up (P<0.05).
Conclusion: The results showed that patients with scaphoid non::::union:::: have improved function after surgical treatment.

Abstract
Background: Influenza viruses are one of the most important etiological agents of res-piratory disease in humans and cause epidemics and pandemics with substantial mor-bidity and mortality worldwide. Vaccination and antiviral treatments are the sole and essential way for the prevention and control of influenza infection. During an influenza epidemic before the production of effective vaccine, antiviral treatments are the first step for the prevention and treatment of influenza infection. Adamantanes and neuraminidase inhibitors are influenza antiviral drugs. Because of the increase of drug resistant viruses, the aim of this study was the evaluation of the antiviral drug resistance in influenza A/H3N2 viruses from 2005-2013 in Iran.
Methods: In this study 50 influenza A/H3N2 viruses isolated in cell culture were tested. All samples were subjected to M and NA gene sequencing at the National Influenza Center, School of Public Health, Tehran University of Medical Sciences. RNA was ex-tracted from 200 µl of cell culture supernatants using the Roche high pure viral nucleic acid kit. RT-PCR with the Qiagen one step RT-PCR kit was done. The expected size of the PCR products were analyzed by electrophoresis using 1% agarose gels. The PCR products were sequenced for finding the drug resistant mutants.
Results: All influenza A/H3N2 viruses except four viruses circulating during 2005-2006 had Ser31Asn mutation at M2 channel protein. In the analysis of neuraminidase gene none of the A/H3N2 viruses had K292R, E119V and N294S mutations responsible for drug resistant strains.
Conclusion: This study showed circulating A/H3N2 viruses was resistant to adaman-tanes but susceptible to neuraminidase inhibitors. The national data analyzed in this re-search may help increase knowledge about influenza virus antiviral drug resistance, which is a global public health concern. The authors suggested continuing this study and also the investigation of antiviral drug resistance of influenza A/H1N1 and B viruses.

Abstract
Background: Differentiated thyroid cancer (DTC) frequently occurs in women at fertility age. One of the cornerstones in treating this malignancy is Radioactive Iodine (RAI) therapy following thyroid resection. In this study, we evaluated the effect of RAI therapy on the fertility rate and pregnancy complications.
Methods: This is a retrospective study on 41 patients with differentiated thyroid cancer, with at least one experience of pregnancy after standard treatment (thyroid resection followed by radioiodine therapy). All patients have been signed a written consent form in initial admission to our department. Furthermore, we asked our patients to fill in a questionnaire about their thyroid cancer and its treatment as well as pregnancy and its complication. As a control group with no different mean age, the same checklist has also been filled in for the patient’s healthy sister too, just related to gravidity and its complications. The complications of pregnancy were registered in these patients and compared with the control group consisted of their healthy sisters. Also, the association of abortion rate with other underlying factors has been assessed. All data has been included in SPSS software, version 22 (IBM SPSS, Armonk, NY, USA) and analyzed using logistic regression. This study conducted at the Nuclear Medicine Department of Ghaem Hospital in Mashhad, from May 2017 to February 2018 with the support of Mashhad University of Medical Sciences, Iran.
Results: No significant difference was noted in the mean age between case (differentiated thyroid cancer) and control groups (P=0.9). The two groups were also statistically similar in terms of pregnancy frequency (P=0.05) and number of alive children (P=0.8). Abortion seems to be the only item in DTC patients which was more than healthy sisters (0.2 versus 0.7) (P=0.003). However, this statistical difference showed no direct relationship with radioiodine treatment (RIT). As in DTC patients before and after RIT, no significant difference has been detected in DTC patients before and after RIT (P=0.48). Birth weight was not statistically different in DTC patients before and after RIT (P=0.66) and between DTC patients and their healthy sisters (P=0.2).
Conclusion: Radioiodine therapy for differentiated thyroid carcinoma has no considerable negative impact on pregnancy, whether on fertility rate or on gravity complications.

Abstract
Background: Mesenchymal stem cell (MSC) transplantation is a promising therapy for kidney repair. This study compared the regenerative effects of feline MSCs (fMSCs) and telmisartan, a renin-angiotensin blocker (RAB), in a feline model of chronic kidney disease (CKD).
Methods: The fMSCs were obtained from 35 Persian cats with CKD and characterized by CD44, CD90, and CD105 markers by using real-time RT-qPCR. The cats were randomly allocated to four groups, fMSCs injection (first group), telmisartan administration (second group), no treatment (third group), and healthy controls (fourth group). The study was conducted in Kerman province from December 2018 to December 2019. The factors that may affect the risk of CKD, such as age, weight, and history of kidney diseases, were considered as independent variables. The presence or absence of CKD was the dependent variable. The cats were followed up for 120 days and evaluated by physical examination, glomerular filtration rate (GFR), blood urea nitrogen (BUN), serum creatinine (SCr), serum urea, alanine transaminase (ALT), urine specific gravity (SG), and kidney histopathology. Statistical analysis was performed using SPSS software (version 20) with two-way ANOVA and Tukey test. P<0.05 was considered statistically significant.

Results: The fMSCs group showed significant improvement in GFR, BUN, SCr, serum urea, SG, and kidney histology compared to the other groups. The fMSCs group also showed increased expression of CD44, CD90, and CD105 genes in the kidney tissue, indicating enhanced stem cell activity. The telmisartan group showed modest improvement in blood pressure and proteinuria, but no significant effect on other parameters. fMSCs transplantation can restore the kidney function and structure in cats with CKD by modulating the apoptosis and proliferation of renal cells. The telmisartan patients benefited from the anti-hypertensive and anti-proteinuric effects of the drug, but not from its anti-fibrotic or anti-inflammatory effects.
Conclusion: fMSCs transplantation was more effective than telmisartan in improving kidney function and reducing kidney damage in cats with CKD. fMSCs may be a potential therapeutic option for CKD patients.
