10.22376/ijpbs.2019.10.1.p1-12 Volume 7 Issue 4 2016 (October - December) This study was designed to evaluate the neuro-ameliorative effect of red ( lessThan i greaterThan Morus rubra lessThan /i greaterThan ) and white berry ( lessThan i greaterThan Morus alba lessThan /i greaterThan ) extracts against Alzheimer´s disease (AD) in male rats. AlCl lessThan sub greaterThan 3 lessThan /sub greaterThan was administered orally to male albino rats (100 mg/kg/day for 6 weeks) while, berry extracts (300 mg/kg/day for six weeks) was administered orally post AlCl lessThan sub greaterThan 3 lessThan /sub greaterThan administration. The data showed markedly elevation in lipid peroxide, apoptotic marker enzyme (caspase-8) and calmodulin (CaM) levels while, reduced glutathione (GSH) level and antioxidant enzyme paraoxanase-1 (PON1) were reduced in AD rats when compared with normal control one. The treatment of rats with AlCl lessThan sub greaterThan 3 lessThan /sub greaterThan induced AD was associated with increase in the 8-OHdG/2-dG ratio and decreased the expression of DHCR24 and FKBP1B genes. However, the treatment of AD-induced rats with red and white berry extracts exhibited low 8-OHdG/ 2-dG ratio and increase the expression of the DHCR24 and FKBP1B genes. The results suggested the attenuated role of berry extracts which could be attributed to the inhibition of reactive oxygen species (ROS), increase in the antioxidant enzymes activity as well as inhibition in the occurrence of apoptotic related enzymes such as caspases-8.
