Abstract:

Nicotine is known to induce oxidative stress in rat tissues and the antioxidant properties of garlic have been reported. This study was designed to determine if the peroxidative damage caused by nicotine administration can be effectively prevented with garlic juice, and vitamin E, a known antioxidant.Four groups of six rats each were divided into: Group I: (control) received 0.2ml of 0.9% normal saline, group II (received nicotine 0.6mg/kg b.w subcutaneously), group III (received nicotine 0.6mg/kg b.w + garlic juice 100mg/kg b.w orally), and group IV (received nicotine 0.6mg/kg b.w + Vitamin E 100mg/kg b.w orally). All animals were treated for 21 days. The pituitary gland, ovary, uterus, heart, liver and kidney of the animals were harvested, weighed and homogenized. Malondialdehyde (MDA), superoxide dismutase (SOD) and reduced glutathione (GSH) were then measured.Concentration of MDA was significantly increased in tissues of nicotine treated rats when compared with the control. In group III and IV, MDA levels were significantly reduced when compared with nicotine group. The activities of SOD and GSH significantly decreased in group II (nicotine only) rat tissues, while it was significantly increased in group III and IV rat tissues. The study showed that garlic juice extract (100mg/kg b.w) and vitamin E (100mg/kg b.w) administration prevented oxidative damage in rat tissues treated with nicotine. The study also showed that vitamin E has a more potent antioxidant activity than garlic juice in preventing nicotine induced oxidative damage in rat. Keywords: Nicotine, Vitamin E, Garlic, antioxidant.
