Objective(s): Long term consumption of ethanol may induce damage to many organs. Ethanol induces its noxious effects through reactive oxygen species production, and lipid peroxidation and apoptosis induction in different tissues and cell types. Previous experiments have indicated the antioxidant characteristics of thymoquinone, the active constituent of Nigella sativa fixed oil, against biologi...

About 80% of breast cancers are estrogen-receptor positive. The research carried out herein focused on the effect of Thymoquinone which is an active compound of Nigella sativa seed on estrogen-receptor positive breast cancer MCF7 cell line. The percentage of apoptotic cells was found using Annexin V-FITC apoptosis detection kit. CycleTEST PLUS DNA Reagent was used to distinguish distribution of...

INTRODUCTION Previous studies have demonstrated that thymoquinone has protective effects against ischemia reperfusion injury to various organs like lungs, kidneys and liver in different experimental models. OBJECTIVE We aimed to determine whether thymoquinone has favorable effects on lung, renal, heart tissues and oxidative stress in abdominal aorta ischemia-reperfusion injury. METHODS Thir...

There are few reports describing the role of p53-dependent gene repression in apoptotic cell death. To identify such apoptosis-associated p53 target genes, we used the pro-oxidant plant-derived drug thymoquinone and compared p53+/+ and p53-/- colon cancer cells HCT116. The p53 wild-type (wt) status correlated with more pronounced DNA damage and higher apoptosis after thymoquinone treatment. A s...

objectives: dependence and tolerance are major restricting factors in the clinical use of opioid analgesics. in the present study, the effects of thymoquinone, the major constituent of nigella sativa seeds, on morphine dependence and tolerance were investigated in mice. materials and methods: male adult nmri mice were made tolerant and dependent by repeated injections of morphine (50, 50, and 7...

In the previous studies the relaxant, anti-cholinergic (functional antagonism) and anti-histaminic effects of Nigella sativa have been demonstrated on guinea pig tracheal chains. To elucidate the main substance responsible for the relaxant effect of this plant, the effect of thymoquinone, one of the main constituent of Nigella sativa was examined in this study. The bronchodilatory effects of th...

BACKGROUND Thymoquinone is the major active principle of Nigella sativa (N. sativa) and constitutes about 30% of its volatile oil or ether extract. N. sativa oil and seed are commonly used as a natural remedy for many ailments. Using modern scientific techniques, a number of pharmacological actions of N. sativa have been investigated including immunostimulant, anti-inflammatory, anticancer, ant...

BACKGROUND: Immunoglobulin-G (IgG) is a product of the initial response to secondary immune response, which accumulates in distal segment nerve after crush injury. Thymoquinone modulates adaptive response. Effect thymoquinone administration on local IgG levels Rattus norvegicus Wistar rats sciatic injury model has not been elucidated.METHODS: This was an experimental study, with 63 that divided...

Objectives: Dependence and tolerance are major restricting factors in the clinical use of opioid analgesics. In the present study, the effects of thymoquinone, the major constituent of Nigella sativa seeds, on morphine dependence and tolerance were investigated in mice. Materials and Methods: Male adult NMRI mice were made tolerant and dependent by repeated injections of morphine (50, 50, and 7...

Cancer is one of the main causes of mortality in the world which appears by the effect of enviromental physico-chemical mutagen and carcinogen agents. The identification of new cytotoxic drugs with low side effects on immune system has developed as important area in new studies of immunopharmacology. Thymoquinone (TQ), derived from the medicinal spice Nigella sativa (also called black cumin) ex...
