abstractantioxidants are effective in prevention and treatment of cardiovascular diseases. lavandula officinalis possesses antioxidant activity, therefore, in this study, the effects of lavandula officinalis extract were investigated on serum lipids levels of rats. experimental mature male wistar rats were treated with 100, 200 or 400 mg/kg/day of lavender ethanolic extract or distilled water f...

background & aim: this experiment was conducted to examine the effect of different levels of echinacea purpurea (ep) in comparison with an antibiotic (flavofosfolipol) on total antioxidant activity (aoa) in serum of broiler chicks. experimental: in this trial 240 one-day-old broiler chicks (ross 308) were weighed and randomly assigned to the 5 treatment groups, each with 4 replicates with 1...

Background: Alopecia Areate (AA) is a recurrent non-scarring patchy hair loss of autoimmune origin in a genetically susceptible individual although environmental factors may be contributory. The aim of this study is to evaluate serum iron and ferritin levels in patients with AA. Methods: Fifty patients of AA and 50 age and sex matched control subjects without any hair loss were studied. Results...

isolation of cell free fetal dna (cffdna) from maternal serum usually leads to very low concentrations of dna impeding further resolving through conventional methods of electrophoresis. although several protocols have been described for capillary electrophoresis (ce) of double stranded dna, they usually need using special polymers or coated capillaries which degrade over time. herein, we propos...

introduction: prostate specific antigen (psa) is one of the most sensitive markers for diagnosis of prostate cancer. immunoradiometric kit (irma) is a common and sensitive method for determination of psa in clinical laboratories. this kit has four major components: solid phase coated with monocolonal antibody, pair antibody labelled with i-125, series of standards in different ranges of concent...

to evaluate the changes of abr values in hyperbilirubinemic newborns, 85 cases with severe jaundice (total bilirubin levels over 16 mg/dl and direct bilirubin less than 2 mg/dl) were selected from those admitted to children's medical center by simple sampling method. these infants had no other problem except jaundice. abr was taken before treatment in all cases and in some (10 cases) after...

objective: this study was planned to investigate whethercoriandrum sativum (c. sativum) is capable of protecting neurons against glucose/serum deprivation (gsd)-induced cytotoxicity. material and methods: the pc12 cells were cultivated for 24 h in standard media (high-glucose dmem containing fetal bovine serum) or for 6 h in gsd condition (glucose-free dmem, without serum) in the absence or pre...

background: in the present study, blood serum level of metals were determined in malarial pa­tients and compared with those in the normal subjects without complication using atomic absorp­tion spectrometer. methods: for the determination of these metals twelve intravenous blood samples each from re­ferred malarial patients and a group of normal subjects were collected and immediately centri­fug...

advanced glycation end-products (ages) are formed by non-enzymatic reaction between reducing sugar and protein. ages play important roles in pathogenesis of diabetic, aging complications, endothelial dysfunction and neurological diseases such as the alzheimer’s disease. therefore compounds that prevent the glycation reaction are purported to have therapeutic effect on patients with diabetes and...

serum fatty acids on 30 healthy lranian women were detemined by a gas chromatographic method. oleic and stearic acids were used as standards. the mean values were myristic acid 5. 7% , palmitic acid 43% , palmitoleic acid 5.3% , stearic acid 8% , oleic acid 21. 3% and linleic acid 16.4% of total fatty acid serum contents.
