Journal of Research in Medical Sciences , 2003,
Abstract: Introduction: It is assumed that the process of schizophrenia effect on patient"s cognitive functions. The aim of this study was to examine and to compare cognitive profile of patients with that of control group. Methods: 40 patients with schizophrenia were selected from Isfahan Noor Hospital. 40 non-patients as control group were selected and matched on the base of age, sex, education, economic status. Cognitive functions of two groups were assessed by WAlS-R. Results: Results show that schizophrenic patients appear at a lower level of IQ than control group. Nonverbal IQ was more impaired than the other kind of IQ in patients. Cognitive profile analysis reveals that patients had low scores on all of the WAlS-R subscles except information and word subscales. Discussion: These findings show that schizophrenic patients in the first episode of theire illness reveal a remarkable impairment on inteligence performance. Cognitive profile analysis indicates that schizophrenic patients performer significatly at a lower level in comparison with control group, in: abstraction, visual - special perception, verbal and non-verbal conceptualization, social judgment, attention, motor-visual organization and mental flexibility.

Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.27114
Abstract: Life on the earth is dependent on dynamic interactions between its physical, chemical and biological components. In fact, all the individual processes are responsible for regulating the environmental equilibrium which can provide biosphere for multiple forms of human life. In order to overcome on shortcomings, the use of immobilized cell bioreactor technology which provides a valuable effective for treatment of waste water is discussed. An immobilized system which in this matter is applied is about absorbed or captured microorganisms in a solid substratum to retain them in a reactor or analytical system. The multiply of these immobilized cells is done when by nutrients be supplied and then migrate to the surfaces which are referred to biofilms. The biofilms can be developed on various support systems such as polypropylene pall, rocks, sands, charcoal, ceramics, and glass beads. The controllable reaction vessels which are used for these colonized surfaces are referred to bioreactors. Bioreactors in both up flows and down flows mode which use of either batch or continuous processes principle can be operated. Synchronic with development in biotechnology, there is also an extensive development in the field of bioreactors like: pumped tower loop reactor (PTLR), liquid impelled loop reactor (LILR), multipurpose tower bioreactor (MTB), fluidized-bed and packed-bed bioreactor, that in this article are discussed them.

Zahedan Journal of Research in Medical Sciences , 2012,
Abstract: Background: Cisplatin is an antineoplastic drug and at high doses is hepatotoxic. Oxidative stress has been proven to be involved in cisplatin-induced hepatotoxicity. Because of antioxidant potential of turnip (Brassica rapa. L) root, the objective of this study was to examine the protective effect of turnip root ethanolic extract (TREE), on cisplatin-induced hepatotoxicity in rat.Materials and Method: Forty male Wistar rats were randomly allocated into four equal groups. Group 1 was used as control; groups 2 and 4 were orally treated with TREE (200 mg/kg) for 15 consecutive days. Groups 3 and 4 received a single intraperitoneal dose of cisplatin (7.5 mg/kg) on the 10th day of the experiment. At the end of experiment, serum levels of aspartate and alanine transaminases, lactate dehydogenase and total bilirubin, albumin and total proteins were assessed. Malondialdehyde, reduced glutathione and activities of superoxide dismutase, catalase and glutathione peroxidase and glutathione reductase were assayed in liver homogenates. Finally, the biochemical findings were matched with histopathological verifications.Results: In group 4, TREE significantly (p=0.0001) decreased the elevated levels of serum biomarkers of hepatic injury and total bilirubin; and significantly increased the reduced levels of serum albumin and total proteins (respectively p=0.001, p=0.032). In this group, TREE significantly (p=0.0001) decreased the lipid peroxidation and elevated the decreased values of hepatic antioxidants. Histopathologically, the changes were in the same direction with biochemical findings.Conclusion: Because of anti-oxidant potentials of TREE, it may have a protective effect against cisplatin induced hepatotoxicity in rats

Journal of Biological Sciences , 2009,
Abstract: Adequate characterization of hypoglycemic effect of ethanolic saffron extract has not been yet done, though the activity has been reported. The scientific evaluation of its hypoglycemic activity was, therefore, explored and compared with the effect of a standard hypoglycemic drug, tolbutamide. In this study, we also report on alteration in patterns of pancreatic islet cells using histopathology and immunohistochemistry of alloxanized diabetic rats treated with ethanolic saffron extract. The ethanolic extract of Crocus sativus L. stigma was administered orally and intraperitoneally at different doses (20, 40 and 80 mg kg-1) to normal rats for finding the more effective hypoglycemic dose and administration route. Acute hypoglycemic effects produced by more effective dose of ethanolic saffron extract on the Fasting Blood Glucose (FBG) levels and effects of the same dose of ethanolic saffron extract on the FBG and plasma insulin levels in alloxanized Mild Diabetic (MD) and Severely Diabetic (SD) rats were assayed. Histopathological and immunohistochemical studies were also carried out on pancreatic islet cells of control and diabetic rats. The dose of 40 mg kg-1 was found to be more effective dose in intraperitoneally (i.p.) route for decreasing Blood Glucose Level (BGL). The extract administered by i.p. route at more effective dose showed an acute hypoglycemic effect in MD and SD rats. Treatment of MD and SD rats for 14 days with the more effective dose significantly reduced the FBG levels in these animals (41.4% MD, 30.7% SD). Serum insulin level showed significant increase in diabetic rats (33.3% MD, 27.3% SD) after 14 days. The histopathological studies of pancreas in ethanolic extract treated diabetic groups showed a reversed damage caused by alloxan to the pancreatic islets as almost normal appearance. In addition, diabetic (MD and SD) rats showed obvious decreases in insulin immunoreactivity and the number of β-cells in pancreas, but the pancreas of extract-treated diabetic rats was improved and the number of immunoreactive β-cells was significantly increased. The control group given saffron extract was not different from the other intact control group considering the insulin immunoreactivity in β-cells. The findings of present study indicate the hypoglycemic and potential antihyperglycemic nature of the extract, helping in regeneration of damaged pancreas in experimental diabetes. Thus, after randomized clinical trials, saffron extract may be implicated as a preventive or therapeutic agent against diabetes mellitus.

Research Journal of Biological Sciences , 2012,
Abstract: Surgical wound infection is a significant cause of post-operative mortality and morbidity in children especially neonates. The aim of the present study was to determine prospectively the incidence of post-operative wound infections in children and to identify the risk factors associated with the development of wound infection. Despite a large series of literatures in adults, there have been a few reports concerning post-operative wound infections in children. All children undergoing operations on the pediatric surgical service during a 4.5 year period in our cente,r were post-operatively followed for 30 days after surgery for the development of a wound infection. The overal incidence of wound infections among 974 children who had undergone the operation was 3.9%. Factors found to be significantly associated with a post-operative wound infection were age of patient (p<0.05) and the amount of contamination during the operation time (p<0.05). There was no significant difference in sex and season of operation. The result of this study demonstrated that wound infection in children is similar to adults, however, in neonates, it is more than adults that is related to the physiologic status.

Research Journal of Biological Sciences , 2012,
Abstract: This research was performed to characterize the hypoglycemic and pancreas-protective effect of ethanolic extract of Crocus sativus L. stigma in alloxanized diabetic rats. The ethanolic extract of Crocus sativus L. stigma was administered orally and intraperitoneally at different doses (20, 40 and 80 mg kg 1) to normal rats. The dose of 40 mg kg 1 was found to be more effective dose in IP route and it decreases Blood Glucose Level (BGL) by 33.9% in normal healthy rats after 6 h of administration. Although, oral route of C. sativus L. also caused significant reductions of blood glucose levels in healthy rats, the effect was minor. The extract administered by IP route at this dose showed an acute hypoglycemic effect in mild and severely alloxan-diabetic rats. Treatment of mild (FBG 120-250 mg dL 1) and severely (FBG 250-300 mg dL 1) diabetic rats for 14 days with the more effective dose (40 mg kg 1) reduces the fasting blood glucose by 41.4% in Mild Diabetic (MD) and 30.7% in Severely Diabetic (SD) rats. After daily treatment with the same dose (40 mg kg 1) of ethanolic saffron extract for 14 days to normal as well as MD and SD rats, the plasma insulin levels were assayed. Serum insulin level showed significant increase in diabetic rats (33.3% MD, 27.3% SD). The histopathological studies of pancreas in ethanolic extract treated diabetic groups showed a reversed damage caused by alloxan to the pancreatic islets as almost normal appearance. The findings of our study indicate the hypoglycemic and potential antihyperglycemic nature of the extract, helping in regeneration of damaged pancreas in experimental dibetes.
