Abstract:
:This study describes the effect of gentamicin, an aminoglycoside antibiotic on iminodipropionitrile (IDPN)-induced abnormal neurobehavioral syndrome in female Sprague-Dawley rats. The animals were exposed to IDPN in the dose of 100 mg/kg/day intraperitoneally for 7 days. Gentamicin (GM) was administered intraperitoneally daily 1 h before IDPN in the doses of 10, 40, and 80 mg/kg body weight in three different groups of rats. One more group of animals received gentamicin alone (80 mg/kg) and served as the gentamicin-alone group. The intensity of IDPN induced characteristic excitation with choreiform, and the circling movement (ECC) syndrome was examined using an observational test battery including dyskinetic head movements, circling, tail hanging, air righting reflex, and contact inhibition of the righting reflex on days 6, 8, 10, 12, 19, 26, and 33. The animals for histopathological observation were sacrificed on day 10, whereas the remaining animals that were used for long-term behavioral studies were sacrificed on day 35 for biochemical observations. The blood and brain samples were collected for the analysis of blood urea nitrogen (BUN), serum creatinine, cerebral malondialdehyde (MDA), conjugated dienes, and lipid hydroperoxides, whereas temporal bones were collected for inner ear histopathology. Our results showed that gentamicin significantly and dose dependently exacerbated the incidence and the severity of the IDPN-induced behavioral syndrome. The histopathology of the inner ear demonstrated more severe loss of sensory hair cells in the crista ampullaris of the rats treated with IDPN plus gentamicin compared to the IDPN-alone treated animals. Concomitant treatment with gentamicin also potentiated IDPN-induced increase in free radical indices, suggesting a possible role of oxidative stress in gentamicin-induced aggravation of IDPN toxicity. Further studies are warranted to determine the role of aminoglycosides in nitrile toxicity and drug-induced movement disorders.
