In vitro production of germ cells improves the understanding of differentiation process of male and female germ cells. Since using embryonic stem cells for this purpose has been associated with tumorogenesis and ethical criticisms, the mentioned cells were suggested to be replaced with some adult multipotent stem cells. In this study, we used Retinoic acid to induce the differentiation of stem cells into germ cells . To find appropriate non invasive source replacement for embryonic stem cells in this study we evaluated differential potentials of Adipocyte Derived Mesenchymal Stem Cells (ADMSCs) to germ like cells.   Methods : To find the differentiation capabilitypurified ADMSCs were obtained and differentiated to osteoblasts and adipocytes by using appropriate culture medium (Alizarin Red S and Oil red-O). Superficial markers for mesenchymal stem cells (expression of CD90 and CD44 and non-expression of CD45 and CD31) were investigated by flow cytometry to confirm mesenchymal lineage production. The cells were differentiated to germ cells in mediums containing Retinoic acid for 7 days. To evaluate germ cells characteristic markers (Mvh and Dazl) flow cytometry and imunoflorescence were used.   Results: Presence of stem cell superficial markers (CD90 and CD44) and absence of endothelial and blood cell markers (CD31 and CD45) were confirmative for the mesenchymal origin of these cells. The cells were able to differentiate into osteoblast and adipocyte cells. This fact was representative for the multipotential entity of the examined cells. After treating the cells with Retinoic acid, flow cytometry and imunoflorescence results showed remarkable expression of germ cells characteristic markers (Mvh and Dazl).   Conclusions: By this study, it was found that germ cell markers were expressed in ADMSCs after adding exogenous Retinoic acid into culture medium.

Therefore, isolation methods of these cells are important. In this study, several methods were compared, while the MACS (Magnetic Activated Cell Sorting) technique cannot be used , we offer the most appropriate method with lowest cellular damage and highest purity .   Methods : methods such as coated flask with Chitosan (7), gelatin (8), plasma (2), gelatin-plasma (2) were compared with MACS (9), From the microscopic views and time of required isolating monocytes (Comparison between the mentioned methods), cell count (9), cell viability (9), the expression of CD14 as a monocyte marker (10) were compared with MACS (9) by using One-way ANOVA and Tukey test.   Results: The findings indicated that lowest cell count was belonged to controlling group and Chitosan, the highest numbers refer to gelatin-plasma and MACS. Moreover, the highest monocytes CD14 expression was observed in gelatin- plasma and MACS method.   Conclusions: Hence it can be concluded that each gelatin and plasma methods were better than the control group in the isolation of monocytes. But covering gelatin with plasma has higher purity than other methods to compare with MACS it can be a good method beside that.

However information on the rate of changes in exercise-induced respiratory parameters associated with sleep quality is not available. The aim of this study was to compare the parameters of the sleep quality and respiratory function in active and none active men.   Methods : The present study is a semi-experimental . Thirty healthy young men with an age range of 20-24 years were enrolled in this study. Then the participants were randomly assigned to either an active (N=15) or none active (N=15) groups. Respiratory parameters including FEV1 (forced expiratory volume in 1second (% , FEV1, MVV (maximum voluntary ventilation VC (vital capacity), FVC ) forced vital capacity), MEF25% and MEF75% ) maximum forced flow rates at 25and 75% of expired FVC) were measured by spirometer. Pittsburg Sleep Quality Index questionnaire (PSQI) was used to evaluate sleep quality. The research data were analyzed using the independent t test, Pearson’s correlation coefficient and Multiple Linear Regression .   Results: The active group showed significant increased in FVC(p=0.023), VC(p=0.002), MVV(p=0.001), FEV1(p=0.001), %FEV1(p=0.031), MEF25%(p=0.026), EF75%(p=0.042) when compared with the none active group. Score of Sleep Quality Index was significantly lower in the active group (p= 0.002). In the active group with regarding to increasing in per unit of, FEV1, MVV, VC, FVC and MEF75 % respectively equal to 0.217, 0.127, 0.370, 0.386 and 0.194 a reduction in per unit score of sleep quality was observed(p>0.05).   Conclusions: The results of this study show the beneficial effect of physical activity by increasing pulmonary volumes and capacities and as a result improving sleep quality. However, correlation analyses show no significant relationship between respiratory parameters and score of sleep quality.

Razi Journal of Medical Sciences RJMS 2228-7043 2228-7051 2014 20 117 The investigation of the role of nitric oxide system in the spatial memory of rats in experimental model of multiple sclerosis Zahedeh Rahimluy Marjani Homeira Hatami Ali Reza AliHemmati   Background: Multiple sclerosis (MS ( is one of the chronic autoimmune diseases of the central nervous system with unknown etiology. Nitric oxide (NO) as a free radical has contradictory effect on the central nervous system and on MS disease. Nitric oxide is one of the distractive factors of the immune system and is a factor in the destruction of myelin. On the other hand, there is an interaction between NO and memory. In this study, the effects of stimulation and suppression of the NO system have been investigated on the memory of MS .   Methods : In this experimental 35 male rats were anesthetized and a cannula was placed in the hippocampus CA1 region, later were divided into five groups, including: control, sham, Ethidium Bromide (EB) (3 μL / rat), L-Arginine (15/1 μg / rat and), EB (3 μL / rat) + L-Arginine (15/1 μg / rat and). The Morris water maze was used for studying the spatial memory. Data analysis was performed by using one way ANOVA.   Results: Administration of EB as the inducer of MS disease caused the impairment of spatial memory, L-Arginine improved spatial learning and memory in healthy rats, L-Arginine improves spatial memory in rats with MS.   Conclusions: In MS rats , L-Arginine improved the spatial memory. It seems that NO by activating intracellular secondary messenger pathways improves the declined spatial memory during MS disease.

Concentration of this protein increases in renal insufficiency but the role of kidney in adiponectin elimination is undetermined. The aim of this study WAS to compare the concentration of serum adiponectin before and after kidney transplantation and its association with renal function after transplant.   Methods : In this cross sectional study, we enrolled candidates with End Stage Renal Disease (ESRD) along with 40 healthy persons for control group. These groups were matched for both age and gender. Concentration of adiponectin was measured with Elisa one day before kidney transplantation (after dialysis) and 14 days after kidney transplantation with stable kidney function.   Results: There was a positive relation between GFR and HDL with adiponectin changes. There was a positive relation between creatinine (p=0.001) and LDL (p= 0.005) distribution between two groups after transplantation. There was a positive relation between GFR, creatinine (p= 0.001) and HDL (p= 0.018) before and after transplantation. Concentration of adiponectin in ESRD patients was higher than among healthy controls. After transplantation concentration of adiponectin was higher than healthy controls. Comparison of before and after transplantation, concentration of adiponectin was lower after transplantation but was higher than controls.   Conclusions: Kidney function is proposed to be an effective factor in adiponectin concentration.

It is known that, in the presence of a predictable postural perturbation, the Central Nervous System (CNS) utilizes Anticipatory Postural Adjustments (APAs) to maintain balance while standing. The main purpose of the current study was to investigate the APAs during self-induced postural perturbation in patients with MS.   Methods : In this case-control study 12 MS female patients selected by simple sampling were studied with 12 control individuals. Female patients with MS and healthy control subjects performed a backward load release task while standing. Electrical activity of six leg and trunk muscles on the non-dominant side of the body was recorded. The magnitudes and latency of anticipatory muscle activity was calculated and compared between the two study groups. Independent-samples t-test was used for statistical analysis.   Results: The results revealed significant APAs deficits in the MS patients reflecting higher latency and reduced magnitude of anticipatory muscle activity.   Conclusions: Hence, it can be concluded that there is an impairment of feed-forward postural control in MS. These results should be considered in the rehabilitation programs for balance training of patients with MS.

Based on various studies, the fear may be effective in the change of behavior. It seems, fear of AIDS according to the knowledge and attitude is effective in preventing HIV infection. So the aim of this study was to investigate the relationship between fear of AIDS, knowledge and attitudes towards AIDS in women of childbearing age.   Methods : This cross- sectional study was conducted on 260 women of childbearing age and Subjects were selected with Convenience Sampling within 6 months to Besat Clinic of Obstetrics and Gynecology. Data were collected using a demographic information check list and two questionnaires to assess knowledge, attitudes and fear of aids through several interview and its validity and reliability was confirmed in this study. Data were analyzed using descriptive statistic such as mean, standard deviation, also with chi square test and pearson’s coefficient.   Result: findings of the study indicated that most women have moderate awareness (55.2%), positive attitudes (95/8 %) and moderate intensity of fear of AIDS (57.5%). Between Knowledge, attitudes and level of education was not any statistical significance but in women’s employment status with the fear of exposure to HIV infection, a significant correlation was observed.   Conclusions: Since the study was first conducted among the following vulnerable groups of people, the results provided useful information on Fear of AIDS in this group and also it suggests that it may necessarily need more extensive research on the subject for a closer look at the relationship between awareness, attitudes correction and subsequently the change in their behavior in order to provid AIDS prevention.
