سابقه و هدف: خانواده فرفیون از جمله خانواده های بزرگ و مهم گیاهان دارویی هستند که دارای بیش از 800 گونه اند. این خانواده مهم از گیاهان را می توان در درمان بیماری های مختلفی نظیر سرطان و دردهای عصبی به کار برد. با توجه به اینکه در مورد گونه euphorbia microsciadia تاکنون مطالعات فیتوشیمیایی انجام نگرفته است، در این تحقیق مورد بررسی قرار گرفت. مواد و روش ها: تحقیق به روش exploratory survey انجام گ...
CaCo-2 cells were used to address the effect of the plant sterol, beta-sitosterol, on cholesterol trafficking, cholesterol metabolism, and apoB secretion. Compared to cells incubated with micelles (5 mM taurocholate and 250 microM oleic acid) containing cholesterol, which caused an increase in the influx of plasma membrane cholesterol to the endoplasmic reticulum and increased the secretion of ...
BACKGROUND The present study was in quested to study the effects of β-sitosterol on methyl nitrosourea (MNU) induced mammary gland carcinoma in albino wistar rats. METHODS Animals were randomized and divided into four groups of eight animals each. Group I (sham control 1 % CMC in normal saline p.o.); Group II (toxic control, MNU 47 mg/kg, i.v); Group III (MNU 47 mg/kg, i.v + β-sitosterol, 10 ...
BACKGROUND β-sitosterol is a cholesterol-like phytosterol, which widely distributed in the plant kingdom. Here, anti-fibrotic effect of the β-sitosterol was studied using the activated human hepatic stellate cell (HSC) model and dimethylnitrosamine (DMN)-induced mouse hepatic fibrosis model. METHOD HSCs were activated by transforming growth factor-β (TGF-β) and the collagen-1 and α-smooth mus...
The intestinal absorption of cholesterol and sitosterol was compared in rats. The intragastric administration of a single emulsified lipid meal containing either 50 mg of [4-14C]cholesterol or [4-14C]sitosterol resulted in the lymphatic absorption of 18.2% and 0.42% of each sterol, respectively, in 6 hr. This difference was unaltered when the mucosal sterol load was equalized by reducing the ch...
The family Polygonaceae is known for its traditional use in the management of various neurological disorders including Alzheimer's disease (AD). In search of new anti-AD drugs, β-sitosterol isolated from Polygonum hydropiper was subjected to in vitro, in vivo, behavioral and molecular docking studies to confirm its possibility as a potential anti-Alzheimer's agent. The in vitro AChE, BChE inhib...
An attempt was made to determine the mechanism for the greater absorbability of cholesterol as compared to sitosterol. Sitosterol-22,23-(3)H in different combinations with cholesterol-4-(14)C, dissolved in 0.8 ml of triolein, was fed to rats with lymph fistulae. Feeding 1.5, 50, or 100 micro moles of sitosterol resulted in a transfer to the lymph in 24 hr of 3-6% of the sitosterol, largely inde...
Background: Recently identified ABCG5/8 transporters are responsible in part for the different absorption rates of campesterol, sitosterol, and cholesterol. These transporters are also expressed in the liver and might regulate biliary sterol secretion. Aims: This study was therefore conducted to determine the biliary secretion rates and hepatic clearances of campesterol, sitosterol, and cholest...
Jejunal fluid secretion induced by perfusion with oleic acid can be reduced by the addition of cholesterol. The present study was performed to test the specificity of this effect by comparing the effects of cholesterol with that of a plant sterol, beta-sitosterol during perfusion of the jejunum in healthy volunteers. In addition, we compared the solubilities of cholesterol and beta-sitosterol i...
