background: oral vanadyl sulfate (vanadium) induces normoglycemia, proliferates beta cells and prevents pancreatic islet atrophy in streptozotocin-induced diabetic rats. soteriological method is used to quantitate the proliferative effects of vanadium on beta-cell numbers and islet volumes of normal and diabetic rats. methods: adult male sprague-dawley rats were made diabetic with intravenous s...

objective: curcumin is a major constituent of turmeric and influences many functions of the brain. in the present study, we investigated the effect of curcumin on yawning induced by apomorphine in rats. materials and methods: curcumin administered orallyfor 10 consecutive days. yawning was induced by subcutaneous (s.c.) injection of apomorphine (a dopamine receptor agonist) and the number of ya...

objective: the present study was hypothesized to investigate the beneficial effects of fresh, aged, and cooked garlic extracts on blood glucose and memory of diabetic rats induced by streptozocine (stz). material and methods: diabetes was induced by an intraperitoneal injection of stz (60 mg/kg body weight). an oral dose of 1000 mg/kg of each garlic extract was given daily for 4 weeks after dia...

objectives:crocin is one of constituents of saffron and has antioxidant property. zinc chloride is one of the common compounds of zinc with antioxidant activity. the present study was aimed to investigate separate and combined treatment effects of crocin and zinc chloride on blood levels of zinc and metabolic and oxidative parameters in diabetic rats. materials and methods:diabetes was induced ...

background: hyperprolactinemia is a common side effect of antipsychotic drugs that requires further investigation. the current study was designed to evaluate dose-dependent effect of chlorpromazine (cpz) on hormonal changes and uterine horn histological structure in rats. moreover, the mammary glands were analyzed to show hyperprolactinemia-induced histological changes. methods: albino wistar r...

introduction: the present study used a histological evaluation method to examine the effects of pentoxifylline (ptx) on healing an experimentally-induced pressure sore in a rat model. materials and methods: there were 36 adult male rats used in this study. under general anesthesia and sterile conditions, we used forceps to create one pressure sore on each rat. a double layer of folded skin from...

objectives: fluoxetine is a selective serotonin re-uptake inhibitor (ssri) widely used for depression, bipolar disorder, anxiety and obsessive-compulsive disorder. the aim of this study was to assess the effect of fluoxetine on orthodontic tooth movement (otm) in rats. materials and methods: forty-five male wistar rats were randomly divided into three groups namely the control group (no medicat...

statins are used as cholesterol-lowering drugs by many patients and have been recently shown to affect bone metabolism. the aim of this study was to determine the effect of atorvastatinon on orthodontic tooth movement (otm) in rats.thirty-six adult male sprague-dawley rats were randomly divided into three groups of 12 samples each. group a, served as control with no medication while groups b an...
