AIM To evaluate the hepatoprotective activity of a hydroalcoholic extract of the bark of Anogeissus latifolia; in vitro in primary rat hepatocyte monolayer culture and in vivo in the liver of Wistar rats intoxicated by carbon tetrachloride (CCl(4)). METHODS In the in vitro study, a primary hepatocyte monolayer culture was treated with CCl(4) and extract of Anogeissus latifolia. Hepatoprotecti...

Activity of L-threonine aldolase in rat liver cytosolic extract was not affected by the omission of alcohol dehydrogenase in a previously established NADPH-linked alcohol dehydrogenase-coupled assay. The liver extract was able to catalyse the dehydrogenation of NADPH with either acetaldehyde (a product of L-threonine aldolase action) or 2-oxobutyrate (a product of L-threonine dehydratase action...

Immature Xenopus laevis were unilaterally nephrectomized and implanted subcutaneously with stage 38 (prefeeding) larvae. Rat kidney extract was injected 8 and 16 days after the operation and the mitotic incidence (MI) in the host and implant tissues was measured by the colcemid metaphase arrest technique. The MI in the kidney of nephrectomized hosts was higher than normal at 8 days but had retu...

In 10 healthy subjects and 10 duodenal ulcer patients the intestinal phase of gastric acid secretion was studied by intraduodenal infusion of a 10% liver extract meal (pH 7) at 400 ml/h for three hours. A gastroduodenal double lumen tube with two balloons was used to block the pylorus and to prevent duodenogastric reflux. Gastric acid response to a duodenal meal of liver extract reached a peak ...

Objectives: The natural origin of medicinal plants does not guaranteed their safety, as there are no sufficient studies on the safety, efficacy and toxicity to support their beneficial claims. Hence, this study aimed at investigating the oral acute toxicity of Adansonia digitata L. fruit shell extract on mice. Methods: Maceration method was employed for the extraction of Adansonia digitata fru...

Background and objectives: Free radicals and other oxidants have important roles in liver cell toxicity. Some natural products are potent scavengers of oxidative agents. Crocus caspius is an endemic species of Caspian forest. Flowers of Crocus genus contain phenolic compound and carotenoid as antioxidant agent. This study investigated the antioxidant and hepat...

Background: Rosa Canina L. is a medicinal plant with many therapeutic applications in traditional medicine. This study aimed to evaluate the effectiveness of the extract of Rosa Canina on liver function, lipid profiles and thyroid hormones in hypercholesterolemic rats. Methods: In this experimental study, 60 male Wistar rats were divided into...

Background Human Wharton's jelly mesenchymal stem cells (HWJMSCs) isolated from medical waste product can be considered as an accessible source of cells in regenerative medicine. Stem cell-derived hepatocytes have poor function and need appropriate niche to reconstruct the liver structure. Therefore, we attempted to find a novel approach in differentiating HWJMSCs into functional hepatic cells ...

Significant increase of liver succinic dehydrogenase (SDH, EC 1.3.99.1) activity was produced by carrageenin-induced edema in rats. Pretreatment with human placental extract inhibited the increased liver SDH activity in a dose-dependent manner. Placental extract was found to have little or no effect on the liver SDH activity in normal rats. Furthermore, heat-induced erythrocyte lysis was inhibi...
