REVERSAL OF CLONIDINE-INDUCED HYPOTHERMIA BY DECAFFEINATED TEA/COFFEE EXTRACT, AND THEIR FRACTIONS IN MICE

Objective: To study the effect of decaffeinated tea extract (DTE) and decaffeinated coffee extract (DCE) and their respective fractions viz: chloroform fractions (DTCf and DCCf), ethyl acetate fractions (DTEa and DCEa), diethyl ether fractions (DTDe and DCDe) and acetone-water fractions (DTAw and DCAw) against clonidine-induced hypothermia in mice. Methods: Clonidine (0.1 mg/kg, i. p.) administered to a group of mice pretreated 30 min before with the dose of DTE or DCE or their respective fractions. Rectal temperature was measured at the time of clonidine administration and thereafter at every 30 min up to 2 h test period. Results: DTE 200 DTE 300 has significantly inhibited clonidine-induced hypothermia. Among the fractions tested, DTE fraction-DTEa 100 and 200 and DCE fractions DCDe 200 and DCAw 200 significantly (p<0.0001) reversed clonidine-induced hypothermia; the effect of DTEa was found to be more sustained. Conclusion: Both, the decaffeinated tea and coffee contain ingredients that reverse clonidine-induced hypothermia, but they are required to do so in very large doses which are not achievable with normally administered doses of decaffeinated tea or coffee

Evaluation of Antioxidant and Anti Parkinsonism Activity of Betaine in Experimental Rats

Aim and Objectives: The present study was aimed to evaluate anti parkinsonium effect of Betaine for its Applications in trigger factors in pathogenesis of Parkinson’s disease and to understand development of new treatments approaches for PD. Betaine is naturally obtained product. It has antioxidant, neuroprotective activity. Hence, we inspected whether betaine can act as a protective agent in 6-OHDA induced oxidative stress on cerebellum of Sprague-Dawleyrats. Material and Methods Thirty-six adult Sprague-Dawley rats were dived into six groups. Rats were received unilateral 6- hydroxydopamine lesions for induction except normal and rats were treated with respective treatment. At the day of 21 rats were sacrificed. Prepared brain homogenate was used for further Biochemical estimation. Result: Betaine showed marked rise in SOD and Catalase activity as well as GSH content subsequently decreasing in the lipid peroxidation process. Our result suggests Betaine to be potent antioxidant at dose 12.5 and 25 mg/kg as compared to standard (L-dopa+Benserazide) and pro-inflammatory cytokines viz: TNF-α, IL-1β and IL-6 were significantly reversed by Betaine as compared to that of standard group (L-dopa+ Benserazide). Discussion and Conclusion: Betaine showed dose dependent effect by reducing LPO level as increasing SOD, GSH and Catalase activity and marked reduced proinflammatory cytokine, hence we conclude that betaine has good anti parkinsonism activity.
