OBJECTIVE Acute respiratory distress syndrome (ARDS) and acute lung injury (ALI) are important clinical problems in thoracic surgery and critical care medicine. Most of the treatment methods are still supportive. Thymoquinone has anti-inflammatory, spasmolytic, bronchodilator and antibacterial effects. We studied its effects on ALI/ARDS in a rat model. METHODS ALI/ARDS was developed in 40 Spr...
nigella sativa seeds have wide therapeutic effects and have been reported to have significant effects against many ailments such as skin diseases, jaundice, gastrointestinal problems, anorexia, conjunctivitis, dyspepsia, rheumatism, diabetes, hypertension, intrinsic hemorrhage, paralysis, amenorrhea, anorexia, asthma, cough, bronchitis, headache, fever, influenza and eczema. thymoquinone (tq) i...
Most of the bacterial pathogens are resistant to existing synthetic antibacterial agents demanding an increasing effort to seek effective phytochemicals as antibacterial agents against such pathogens. Nigella sativa L. (black cumin) seeds play an important role in folk medicine and some of its major constituents are reported to be pharmacologically active. In this present work, black cumin seed...
Thymoquinone (TQ), the predominant bioactive constituent derived from the medicinal spice Nigella sativa (also known as black cumin), has been applied for medical purposes for more than 2,000 years. Recent studies reported that thymoquinone exhibited inhibitory effects on the cell proliferation of several cancer cell lines. This study was performed to investigate the antitumor and anti-angiogen...
OBJECTIVE 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 75...
Neuroprotective effects of thymoquinone against transient forebrain ischemia in the rat hippocampus.
Increasing evidence demonstrates that oxidative stress plays an important role in brain injury in experimental models of brain ischemia. Thymoquinone, the main constituents of the volatile oil from Negella sativa seeds, is reported to possess strong antioxidant properties. Hence, the present study was undertaken to evaluate the neuroprotective effect of thymoquinone against transient forebrain ...
We examined the thymoquinone induced inhibition of purified F1 or membrane bound F1FO E. coli ATP synthase. Both purified F1 and membrane bound F1FO were completely inhibited by thymoquinone with no residual ATPase activity. The process of inhibition was fully reversible and identical in both membrane bound F1Fo and purified F1 preparations. Moreover, thymoquinone induced inhibition of ATP synt...
Thymoquinone, a component derived from the medial plant Nigella sativa, has been used for medical purposes for more than 2,000 years. Recent studies reported that thymoquinone exhibited inhibitory effects on cell proliferation of many cancer cell lines and hormone-refractory prostate cancer by suppressing androgen receptor and E2F-1. Whether thymoquinone inhibits tumor angiogenesis, the critica...
BACKGROUND The goal of our study was to determine the therapeutic effects of thymoquinone in a dose-dependent manner in a model of neuropathic pain following an experimentally applied spinal cord injury (SCI). METHODS Fifty female adult Wistar albino rats weighing between 220 and 260 g were included in the study and were divided into 5 groups as follows: Group S (sham), Group C (control), Gro...
