Does docosahexaenoic acid ameliorate aluminum induced biochemical and morphological alteration in rat cerebellum? Context: The omega-3 polyunsaturated fatty acids (PUFA), docosahexaenoic acid (DHA) have well-characterized effects on inflammation and oxidative stress and may have neuroprotective effects in a number of neurodegenerative conditions including AD. Brain tissue contains large amounts of polyunsaturated fatty acids, which are particularly vulnerable to free radical injury. The present study attempts to examine protective effects of docosahexaenoic acid (100 mg/kg body weight) and on aluminum (100 mg/kg b. wt. of AlCl3) mediated oxidative damage in the cerebellum in male albino rats along with the motor and learning ability and morphological changes. Twenty four male Rattusnorigious, Wistar strain rats (weight 220 ± 10 grams) were randomly divided into four groups (n = 12) viz. Group 1 served as control treated with normal saline, Group 2 treated with 100mg/kg body weight of DHA, Group three treated with 100 mg/kg body weight of AlCl3 and Group four treated with 100mg AlCl3 + 100 mg DHA for 90 days. Dose was directly introduced into the rat pharynx via a feeding cannula to rats for 90 days. Behavioral tests followed by biochemical analysis was performed. A significant decrease in the antioxidant status (superoxide dismutase, catalase, glutathione peroxidase and glutathione) and increased lipid peroxide levels and protein carbonyl content in aluminum exposed rats was noted. After DHA supplementation these effects were reversed. Moreover, DHA also significantly (p<0.05) prevented aluminum induced dysfunctioning of the motor and learning ability. The light microscopic studies revealed altered Purkinje's neurons and granular layer. These changes were not seen in the DHA treated rats.

On the basis of our results it may be concluded that Al may be linked with cerebellar degeneration and neuromuscular disorders while DHA helps to prevent these alterations. Final Decision: yes
