The present paper deals with the study of a D-homothetic deformation of an extended generalized ϕ-recurrent (LCS)2n+1-manifolds their geometrical properties are discussed. Finally, we construct an example of an extended generalized ϕ-recurrent (LCS)3-manifolds that are neither ϕ-recurrent nor generalized ϕ-recurrent under such deformation is constructed.

Protective efficacy of 2-PAMCl, atropine and curcumin against dichlorvos induced toxicity in rats

The effect of 2- pyridine aldoxime methyl chloride (2-PAMCl) and atropine with or without curcumin was investigated in dichlorvos (2,2-dichlorovinyl dimethyl phosphate; DDVP) induced toxicity in rats. Rats were exposed to DDVP (2 mg/kg sub-cutaneously) once daily for the period of 21 days. Post DDVP exposure, rats were further treated with 2-PAMCl (50 mg/kg intramuscular, once daily) + atropine (10 mg/kg, i.m. once daily) with or without curcumin (200 mg/kg; oral; once daily) for further 21 days. We observed a significant increase in lipid peroxidation (LPO), reactive oxygen species (ROS), oxidized glutathione (GSSG), while there was a significant decrease in antioxidant enzymes, brain acetylcholinesterase (AChE) and 5-hydroxy tryptamine (5-HT) activity on DDVP exposure of rats. These alterations were restored significantly by co-administration of 2-PAMCl + atropine in DDVP exposed rats. Curcumin when co-supplemented with 2-PAMCl + atropine also significantly protected serum aspartate aminotransferase (AST) and restored brain AChE activity and 5-HT level in animals sub-chronically exposed to DDVP. Histopathological observations along with biochemical changes in rat blood and tissues revealed significant protection offered by 2-PAMCl + atropine against DDVP. The results indicate that DDVP-induced toxicity can be significantly protected by co-administration of 2-PAMCl + atropine individually, however, curcumin co-supplementation with 2-PAMCl + atropine provides more pronounced protection, concerning particularly neurological disorders.
