Background And Purpose:
The objective of this work is to study the dose-dependent effect of combination therapy with dipyridamole and triflusal over that of triflusal alone on infarct size after middle cerebral artery occlusion (MCAO) ischemia.
Materials And Methods:
Male Wistar rats were subjected to a permanent MCAO in the right hemisphere. Rats received triflusal alone and with dipyridamole via oral route. Three days after surgery, infarct volumes were measured.
Results:
The lower dose regime of triflusal (10 mg/kg) and dipyridamole (200 mg/kg) caused the greatest decrease in infarct size compared with higher dose regime of triflusal (30 mg/kg) and dipyridamole (200 mg/kg) (P <.01), triflusal (30 mg/kg) alone (P <.07), and vehicle-treated controls.
Conclusions:
The lower dose combination of dipyridamole and triflusal appears to be more effective than triflusal alone after MCAO-induced cerebral ischemia. Therefore, there is a strong rationale to continue to examine the protective effects of triflusal and dipyridamole after cerebral ischemia.

Esters to Alcohols: Hydride Reductions
Lithium aluminum hydride is a source of hydride ions and functions as a nucleophile. The mechanism proceeds in three steps. Firstly, the nucleophilic hydride ion attacks the carbonyl carbon of the ester to form a tetrahedral intermediate. Subsequently, the carbonyl group re-forms,...
Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
