Objective: Finding compounds that could be used for prevention of atherosclerosis (AS) is highly desired. The present study evaluated the protective effects of Urtica dioica (UD, commonly known as stinging nettle) leaf ethanolic extract against high-fat diet-induced AS in rats. Materials and Methods: In this study, 40 male adult Sprauge-Dawley rats were randomly allocated to 4 equal groups and ...

ba ckground: liver cancer is one of the deadly cancers with high prevalence in the east asia. likewise most of diseases, herbs and herbal medicine could be an easy and cost effective tool in prevention and possible cancer treatment. the present study investigated the ability of orthosiphon stamineus benth decoction to protect liver against hepatocellular carcinoma in carcinogenesis-induced anim...

The aim of our study was to evaluate the mineral composition (Zn, Cu, Ca, Fe, Mg, P) of breast tumor tissue and hair, and to investigate the role of Zn and Cu contents in diet on tumor development, with DMBAinduced rat breast cancer being the experimental model. Female Sprague-Dawley rats were divided into study groups which, apart from the standard diet, were treated with Zinc ions (Zn) or Cop...

The response of nutrient status and biochemical processes in (i) Wistar and (ii) spontaneously hypertensive (SHR) rats upon dietary intake of selenium- (Se-) enriched defatted rapeseed (DRS) and/or vitamin E fortification was examined to assess the health benefit of DRS in animal nutrition. Twenty-four individuals of each type of rat were used: The control group was fed with an untreated diet (...

OBJECTIVES To see the effect of dietary administration of omega 3-fatty acid formula on the vaginal cells of postmenopausal rats. METHODS Three-week-old female Wistar/ST rats were raised after one week of adjustment period. The rats were then divided into three groups, for three different kinds of diet; general diet, 1% omega-3 fatty acid diet, and 2% omega-3 fatty acid diet. After eight week...

introduction: it was shown in a previous study, that mcpip, a cilostamide derivative, increased atrial contraction force without changing contraction rate. to improve this property, two new derivatives of cilostamide were synthesized and their effects on pde3 activity and isolated rat atria contraction were investigated. methods: the inhibitory effect of each compound on pde3 enzyme was determi...

Gas chromatography/mass spectrometry revealed the presence of both carbon disulfide (CS2) and carbonyl sulfide (COS) on rat breath. Behavioral experiments indicated that rats exposed to an unfamiliar diet moistened with CS2, like rats exposed to an unfamiliar diet placed on the fur of an anesthetized rat, subsequently exhibited enhanced preference for the unfamiliar diet. Rats in experimental g...

In search of an adequate model for the human metabolic syndrome, the metabolic characteristics of Wistar rats were analysed after being submitted to different protocols of high fructose ingestion. First, two adult rat groups (aged 90 d) were studied: a control group (C1; n 6) received regular rodent chow (Labina, Purina) and a fructose group (F1; n 6) was fed on regular rodent chow. Fructose wa...

The effect of ascorbic acid deficiency on serum levels of high density lipoprotein- (HDL-), low density lipoprotein- (LDL-), very low density lipoprotein- (VLDL-) and chylomicron-cholesterol was examined in ODS-od/od rat (ODS rat), that is a rat mutant unable to synthesize ascorbic acid. Male ODS rats were fed an ascrobic acid-free diet for 20 days. In another two groups, the diet supplemented ...
