AIMTo evaluate the protective effects of Hibiscus sabdariffa (Roselle) and Zingiber officinale (Ginger) against cisplatin-induced reproductive toxicity in rats and to study the mechanisms underlying these effects.

METHODSEthanol extracts of H.sabdariffa or Z.officinale (1g/kg x day) were given p.o. to male albino rats for 26 days, which began 21 days before a single cisplatin i.p. injection (10 mg/kg body weight).

RESULTSExtracts of H.sabdariffa and Z.officinale reduced the extent of cisplatin-induced sperm abnormality and enhanced sperm motility. Both extracts restored the control level of malondialdehyde (MDA) (lipid peroxidation marker) in the cisplatin-treated testis. The cisplatin injection induced decline in the levels of superoxide dismutase (SOD), reduced glutathione (GSH) and catalase (CAT) were significantly reversed to control levels in groups where cisplatin was preceded by the administration of either H.sabdariffa or Z.officinale.

CONCLUSIONBoth H.sabdariffa and Z.officinale treatment increased the activities of testicular antioxidant enzymes and restored sperm motility of cisplatin-treated rats. The protective effects of tested plants are, therefore, suggested to be mediated by their potent antioxidant activities.

AIMTo evaluate the protective effects of ginger (Gin) and roselle (Ros) against testicular damage and oxidative stress in a cisplatin (CIS)-induced rodent model. Their protective effects against CIS-induced apoptosis in testicular and epididymal sperms is also investigated.

METHODSEthanol extracts of Gin or Ros (1 g/kg.day) were given orally to male albino rats for 26 days. This period began 21 days before a single CIS intraperitoneal injection (10 mg/kg body weight).

RESULTSGin or Ros given orally significantly restored reproductive function. Both tested extracts notably reduced the CIS-induced reproductive toxicity, as evidenced by restoring the testis normal morphology. In Gin and Ros, the attenuation of CIS-induced damage was associated with less apoptotic cell death both in the testicular tissue and in the sperms. CIS-induced alterations of testicular lipid peroxidation were markedly improved by these plant extracts.

CONCLUSIONThe present results provide further insights into the mechanisms of protection against CIS-induced reproductive toxicity and confirm the essential anti-oxidant potential of both examined extracts.
