Abstract
BackgroundTraditionally various human diseases of kidneys, hormonal imbalance and sexual diseases are treated with Launaea procumbens (L). In the present study protective effects of methanolic extract of Launaea procumbens (LPME) was evaluated against CCl4-induced oxidative damages in rat testis.MethodsTo examine the protective effects of Launaea procumbens on testis against oxidative stress of carbon tetrachloride in male rat, 30 male albino rats were equally divided into 5 groups (6 rats). First group was given standard diet and drinking water. Second group received CCl4 3 ml/kg intraperitoneally (30% in olive oil). Third and forth were given orally 100; 200 mg/kg b.w., in 99.8% dimethyl sulphooxide (DMSO), Launaea procumbens methanolic extracts (LPME) after 48 h of CCl4 treatment twice a week and sixth group received only LPME in DMSO at a dose of 200 mg/kg b.w., for four weeks. Protective effects of Launaea procumbens were observed on sperm concentration, motility and morphology, serum reproductive hormonal level, activity of antioxidant enzymes, lipid peroxidation (TBARS) and DNA damages.ResultsResults of the present study revealed that treatment of CCl4 significantly (p < 0.01) reduced sperm concentration and motility comparatively to controls. Level of testosterone, luteinizing hormone and follicle stimulating hormone, were depleted markedly (p <0.01) with treatment of CCl4. In addition, CCl4 induction in rats reduced activities of antioxidant enzymes while increased lipid peroxidation and DNA damages. Co-administration of LPME significantly (p <0.01) improved these alterations in improving of hormonal level, activities of antioxidant enzymes and lipid peroxidation near to control rats.ConclusionFrom the results it is suggested that Launaea procumbens methanolic extract has the ability to protect testis against oxidative damages, possibly through antioxidant effects of its bioactive compounds.
Highlights
Various human diseases of kidneys, hormonal imbalance and sexual diseases are treated with Launaea procumbens (L)
Male sexual dysfunction composed of several problems associated with sperm concentration, motility and hormonal imbalance e.g., low testosterone level, which are caused by alcoholism, drug abuse, aging and cigarette smoking, anti depressant drugs and exposure of toxic chemicals [1,2,3]
Carbon tetrachloride is an industrial solvent cause kidney, lungs and testicular damages in experimental animals [4] triggers oxidative damages through free radicals produced from CCl4 metabolism [5]
Summary
Various human diseases of kidneys, hormonal imbalance and sexual diseases are treated with Launaea procumbens (L). In the present study protective effects of methanolic extract of Launaea procumbens (LPME) was evaluated against CCl4-induced oxidative damages in rat testis. Male sexual dysfunction composed of several problems associated with sperm concentration, motility and hormonal imbalance e.g., low testosterone level, which are caused by alcoholism, drug abuse, aging and cigarette smoking, anti depressant drugs and exposure of toxic chemicals [1,2,3]. Launaea procumbens is traditionally used in the treatment of rheumatism [12], kidney dysfunction [13], reproductive disorder and hormonal imbalance in male [14,15]. The present study was arranged to evaluate the traditional use of methanol extract of Launaea procumbens versus carbon tetrachloride induced oxidative stress associated reproductive hormonal changes and lipids peroxidation in rats
