Background: Finding a treatment for diabetes that does not have side effects has remained elusive. Among natural agents, much attention has been focused on phenolic compounds. For both their medicinal and nutritional value, barberry plants are of particular interest. Berberis vulgaris is known for its medicinal benefits in Iranian traditional medicine. In this study, we investigated the biological activities of B.vulgaris in a rodent model of experimentally induced diabetes. Method: The fasting blood glucose (FBG), insulin, malondialdehyde (MDA), and total antioxidant levels were measured in experimental groups of rats, including normoglycemic control, diabetic control, and diabetics treated with B.vulgaris, and the gene expression of the stress proteins HSF-1, HSP27, and HSP70 as well as the enzymes glucokinase (GK) and glucose 6-phosphatase (G6P) were assayed by real-time PCR.
Aims: Turnip is one of the most consumed medicinal plants that seem to have advantageous efficacy on hyperlipidemia. The present work was undertaken to evaluate the hypolipidemic activity of aqueous extract of Brassica rapa root on hyperlipidemic rats. Materials & Methods: In this experimental study 40 male Wistar rats were divided into 5 equal groups; normal control, hyperlipidemic control (1ml normal saline once a day), Atorvastatin (10mg/kg of body weight per day) and aqueous extract of Brassica rapa root groups (200 and 400mg/kg of body weight per day) were treated for 10 days. After 18h fasting in 11 th day, hyperlipidemia was induced by a single intraperitoneal (IP) injection of triton WR1339 (300mg/kg of body weight) in all groups except normal control. 24 hours after injection, blood collection was done and plasma analyzed for lipid profiles. Data was compared between group s by ANOVA and Tukey tests in SPSS 18 software. Findings: Aqueous extract of Brassica rapa root inhibited the elevation of plasma total cholesterol level at the dose of 200mg/kg of body weight. The extract also decreased LDL cholesterol and triglyceride levels in hyperlipidemic rats significantly but in compare to normal control group these levels were significantly high (p<0.05). Conclusion: The consumption of turnip may act as a potent antihyperlipidemic nutrient for patients with dyslipidemia, cardiovascular and diabetes diseases.
Abstract:Many different dietary supplements are currently marked for the management of hepatic illness, but the evidence for effectiveness is mixed. The aim of this study was to evaluate the effect of white and green tea extracts in a rifampicininduced hepatic damage model of rats. In this study 55 male wistar albino rats were divided into 11 groups of 5 animal, named: normal control, hepatotoxic control with rifampicin (150 mg/kg), hepatotoxic with silymarin, hepatotoxic treated with green tea (250 and 500 mg/kg aqueous extract), hepatotoxic treated with white tea (250 and 500 mg/kg aqueous extract) and preventive groups of green and white tea with mentioned above doses. After 3 weeks treatment with green and white tea, a significant reduction in total cholesterol, triglyceride, LDL cholesterol, malondialdehyde and liver enzymes was observed. In the cases of white tea these changes was notable and dose-dependently improved liver function compared with green tea. The results obtained in this study suggest white tea is much more effective than green tea for prevention and treatment of druginduced liver injury.
Allergic disorders are among the most common diseases around the world especially in children. Many factors contribute to the pathogenesis of atopic disorders, but early events during the pregnancy are very important. The aim of this study was to evaluate the level of cord blood immunoglobulin E (CB-IgE) and its association with maternal in a group of Iranian newborns. In a crosssectional study, 163 pregnant women randomly selected and information about pregnancy and atopy were taken by questionnaire. Blood samples of mothers and matched cord blood were collected and total serum IgE levels were measured by enzyme-linked immunosorbent assay (ELISA) method. To rolling out the possibility of contamination with maternal blood, total IgA was checked for all the cord blood samples. Sixteen percent of mothers had the history of atopic diseases and the mean IgE level was significantly higher in an atopic than nonatopic mothers (241 vs 102, P < 0.001). About 73.9% of cord blood samples, had high IgE level (>0.9 IU/mL). The level of cord blood IgE (CB-IgE) was not significantly different in male and female newborns (2.14 vs 2.15 IU/mL). There was no significant correlation between maternal factors such as age, pregnancy variables, allergens exposure, smoking, and maternal IgE with cord blood IgE.The results of this study showed that CB-IgE is high in a remarkable number of samples; independent of maternal or fetal factors. Further studies need to evaluate the reasons for the high level of IgE in cord blood in our area.

Background: Several genetic alterations in cell growth regulatory genes, such as BRAF, are associated with colorectal cancer. Due to the introduction of biological agents designed to treat cancer, diagnostic tests using nucleic acids extracted from formalin-fixed and paraffin-embedded tissues are becoming more common. Objective: This study aimed to determine the incidence of BRAF mutations in colorectal cancer patients. Materials and methods: 50 paraffin-embedded cancer specimens were obtained from Imam Reza Hospital of Birjand in Iran. PCR was used to amplify and sequence the BRAF gene exon 15, which was extracted from paraffin-embedded tissue using an improved technique. Results: 2/43 (4%) of patients with colorectal cancer exhibited the BEAF V600E mutation. Most of the mutations occurred in patients over 50 years of age Conclusion: To understand how genetics and environment interact to influence the low incidence of BRAF mutations in the east of Iran, further research is needed to determine what is driving this low incidence of BRAF mutations and what factors contribute to it.
