The role of ascorbic acid, selenium, and glutathione on benzo[a]pyrene-induced carcinogenesis in wistar rats.

Purpose: The carcinogenic action of polycyclic aromatic hydrocarbons (PAHs) can be inhibited by endogenous or exogenous compounds. This study was designed to elucidate the modifying action of 3 endogenous inhibitors- ascorbic acid (vit C) used alone, and selenium (Se) used in combination with glutathione (GSH).

Materials And Methods: Chemical carcinogenesis was induced by benzo[a]pyrene(BaP).

Effects of Cupressus sempervirens cone extract on lipid parameters in Wistar rats.

Background: Lipid-lowering drugs have been developed to treat hyperlipidemia, but they are expensive, while serious side-effects may occasionally occur. In Albania, a hydroalcoholic extract of the cones of Cupressus sempervirens is used to treat a variety of disorders, including hyperlipidemia. The purpose of our study was to assess the effects of Cupressus sempervirens cone extract (CSE) on the lipid profile of Wistar rats.

Antiproliferative and anticarcinogenic effects of an aqueous preparation of Abies alba and Viscum album se abies, on a L-1210 malignant cell line and tumor-bearing Wistar rats.

Extracts of plants have been widely tested for possible anticarcinogenic properties. In the present study a traditional remedy, consisting of an aqueous extract of mixed parts of the tree Abies alba and its mistletoe Viscum album se abies was tested on benzo(alpha)pyrene(BaP)-induced tumors in Wistar rats and on the L-1210 malignant cell line. Two main groups of male Wistar rats subcutaneously injected by 10 mg of BaP, a dose inducing 100% carcinogenesis, a control group (C-G, 15 rats) and a treatment group(TR-G, 18 rats), were used for the study.
