Osteoporosis is a medical condition which affects millions of men and women. People with osteoporosis have low bone mass that places them at increased risk of bone fracture. A promising approach is developed as alternative (non pharmaceutical) strategies for bone maintenance, as well as for the prevention and treatment of osteoporosis. Certain plants from the different families have shown the g...

Background Thymoquinone is one of the active ingredients of black cumin (Nigella sativa L.) essential oil possessing antiinflammatory, antineoplastic, neuroand hepatoprotective properties. Some of these properties were attributed to an antioxidant activity of thymoquinone, which seems to be unlikely from its structure. Because the lipophilic thymoquinone exhibits a structural similarity with th...

BACKGROUND Hashimoto's thyroiditis is an autoimmune disorder and the most common cause of hypothyroidism. The use of Nigella sativa, a potent herbal medicine, continues to increase worldwide as an alternative treatment of several chronic diseases including hyperlipidemia, hypertension and type 2 diabetes mellitus (T2DM). The aim of the current study was to evaluate the effects of Nigella sativa...

OBJECTIVE To examine the preventive effect of a hydro-ethanolic extract of Nigella sativa on the tracheal responsiveness and white blood cell count in the lung lavage fluid of sensitized guinea pigs. METHODS Three groups of guinea pigs sensitized to intraperitoneally injected and inhaled ovalbumin were given drinking water alone (group S), drinking water containing a low concentration of N. s...

In previous studies, the relaxant effect of Tymus vulgaris has been demonstrated on guinea pig tracheal chains. Therefore, in the present study, the relaxant effects of n-hexane, dichloromethane, methanol and aqueous fractions of Tymus vulgaris on tracheal chains of guinea pigs were examined. The relaxant effects of four cumulative concentrations of each fraction (0.4, 0.8, 1.2 and 1.6 g%) in c...

caused by thioacetamide (20 mg/kg body weight) in albino rats for a period of eight week. A significant (p<0.05) improvement in the altered levels of bilirubin, albumin, total protein, alanine transaminase, alkaline phosphatase, γ-glutamyl transferase was observed after treatment with 10 ml/kg body weight of Nigella sativa oil. Antioxidant enzymes like catalase, superoxide dismutase glutathione...

1. Only two serologically different proteins were found in the unheated culture filtrates of both virulent and slightly virulent tubercle bacilli. One of them was the protein which had a sedimentation constant of 3.4 S, and the other was in filtrate fractions with a constant of 2 S. 2. That these proteins were distinct was demonstrated by three methods: quantitative precipitin and precipitin ab...

The superoxide (O2-) forming NADPH oxidase complex of resting phagocytes can be activated in a cell-free system by certain anionic amphiphiles, such as sodium dodecyl sulfate (SDS). For O2- production to occur, the participation of both membrane-associated and cytosol-derived components is required. The purpose of this investigation was to isolate and characterize the membrane component of NADP...

Paracetamol (APAP-Acetaminophen) has been used extensively as antipyretic drug. The purpose of this study was to evaluate the ameliorative role of silymarin or/and Nigella sativa extract against APAP-induced hyperlipidemia in male mice at the biochemical, levels. The mice were divided into seven groups (10/group). The first group was served as control. While, the second group was treated with d...

PURPOSE The aim of this study was to determine the toxic effect of Nigella sativa powder on the liver function which was evaluated by measuring liver enzymes and through histopathological examination of liver tissue. METHODS Twenty four male Sprague Dawley rats were allotted randomly to four groups including: control (taking normal diet); low dose (supplemented with 0.01 g/kg/day Nigella sati...
