| Summary: | D-galactose induced neurotoxicity is well known model
for studying aging and related oxidative damage and memory impairment.
Aging is a biological process, characterized by the gradual loss of physiological
functions by unknown mechanism. Centella asiatica, Indian pennywort has been documented
in the treatment of various neurological disorders including aging. Therefore,
present study has been conducted in order to explore the possible role of Centella
asiatica against D-galactose induced cognitive impairment, oxidative and mitochondrial
dysfunction in mice. Chronic administration of D-galactose (100 mg/kg s.c.) for
a period of six weeks significantly impaired cognitive task (both in both Morris water
maze and elevated plus maze) and oxidative defense (Increased lipid peroxidation,
nitrite concentration and decreased activity of superoxide dismutase,
catalase and non-protein thiols) and impaired mitochondrial complex
(I, II and III) enzymes activities as compared to sham group. Six weeks Centella asiatica
(150 and 300 mg/kg, p.o) treatment significantly improved behavioral alterations,
oxidative damage and mitochondrial enzyme complex activities as compared to contro
l (D-galactose). Centella asiatica also attenuated enhanced acetylcholine esterase
enzyme level in D-galactose senescence mice. Present study highlights the protective
effect of Centella asiatica against D-galactose induced behavioral, biochemical and mitochondrial dysfunction in mice.
