Cerebroprotective Actions of Triticum aestivum Linn Powder and Bauhinia purpurea Flower Powder in Surgically Induced Cerebral Infraction in Rats.

UNASSIGNED

The prime objective of this study is to evaluate the cerebroprotective actions of Triticum aestivum (wheatgrass) powder and Bauhinia purpurea flower (dev kanchan) powder against the experimentally induced global ischemia reperfusion injury in rats.

UNASSIGNED

In the first phase of the studies, 1 h before the surgical procedure, the Wistar rats were orally served with varied doses of wheatgrass powder (5, 10, 30, and 100 μg/kg) and Bauhinia flower powder (30, 100, 200, and 300 μg/kg), respectively. The ischemia was induced by 30-min bilateral carotid artery occlusion in succession to reperfusion for 4 h. It was proved that the wheatgrass powder and Bauhinia flower powder yielded a significant, dose-dependent cerebroprotection in terms of reduction in cerebral infarct size when compared with the control group. Coming to the second phase of the studies, a certain potential dose of 10 μg/kg of wheatgrass and 200 μg/kg of Bauhinia flower powders was selected keeping the protective action in view, and the animals were treated for 15 days.

UNASSIGNED

The major findings of the study are that wheatgrass and Bauhinia flower powders significantly augmented the magnitude of the antioxidant enzymes, viz., super oxide dismutase and catalase, and further reduced the levels of lipid peroxidation.

UNASSIGNED

The present study clearly showed that the wheatgrass powder and Bauhinia flower powder possess significant antioxidant properties that may act as a key ingredient in various ayurvedic preparations for the treatment of various diseases like cerebral ischemic reperfusion injury.

CONCLUSIONS

The wheat grass contains high amount of bioflavonoids, alkaloids, SOD etc which are responsible for anti oxidant activity.The Bauhinia purpurea contains glycosides, flavonoids and also plays a major role in DPPH activity which is responsible for anti oxidant activity.The wheat grass (10 mg/kg) and bauhinia (200 mg/kg) significantly(P < 0.0001) reduced the percentage of infract size when compared to Ischemia reperfusion control group.The wheat grass (10 mg/kg) and bauhinia (200 mg/kg) significantly (P <0.0001) reduced the lipid peroxidation (MDA) and increased SOD and Catalase.
