Résumé
Aminoglycosides are the commonly used antibiotics against Gram negative bacteria. Their clinical applications are limited due to nephrotoxic side effects. Therefore, the current study was undertaken in an attempt to increase the use of these drugs without causing nephrotoxicity by exploring the nephroprotective effects of a medicinal plant with high flavonoid contents and strong antioxidant properties, namely Valeriana wallichii. A daily dose of 200mg/kg of the extract derived from V. wallichii was employed for a period of three weeks. The results obtained revealed that co-therapy of extract with gentamicin protected some changes in renal functions; however, failed to provide a complete protection as assessed by biochemical, physiological and histological parameters. It can be concluded from the current findings that V. wallichii failed to deliver protective effects against gentamicin induced renal damage in spite of strong flavonoid contents and antioxidant properties
Résumé
Cinnamomum zeylanicum has strong antioxidant properties and has been presented to have nephroprotective effects. Present work was aimed to study the nephroprotective property of the plant extract through urinary enzymes excretion, to confirm its protective effects and to observe the antibacterial activities of gentamicin in combination with the plant extract. 200mg/kg/day of the plant extracts were administered alone and as co-therapy with gentamicin. Urinary lactate dehydrogenase [LDH] and Urinary alkaline phospatase [ALP] excretions were observed through reagents kits with the help of Power-Lab 300. Antibacterial activities were assessed for gentamicin alone and in combination with the extract. Present study showed that the plant extract have excess quantity of flavonoids, which may responsible for attenuating the excessive excretion of urinary LDH. However, Urinary ALP excretion was found remained same throughout the study period in all experimental groups; might be detected in acute damage. Further, the plant also proved to have no decreasing impact on the antibacterial activities of gentamicin
