Objective: To study the improvement of polygala tenuifolia and rhizoma acori tatarinowii in treating cognitive impairment of diabetes mellitus rats. Method: Diabetic rats were established by intraperitoneal injection of Streptozotocin for 3 months. The polygala tenuifolia and rhizoma acori tatarinowii decoction were made. The rats were divided into 5 groups:control group
model group
and polygala tenuifolia and rhizoma acori tatarinowii group (large dose group
medium dose group and small dose group). observed the change of rat's ability of learning and memory function observed were by the way of water maze and examination of the blood serum methylglyoxal through Gas Chromatography-Mass Spectrometry.The percentage of neuron apoptosis was examined through flow cytometry. Result: In the water maze experiment
it was shown that rats in model group needed more time to swim to the platform than the control group
and polygala tenuifolia and rhizoma acori tatarinowii could significantly reduce the swimming time to platform(P<0.01). It was shown that the serum methyglyoxal of model group increased about 2.5 times more than the control group
and polygala tenuifolia and rhizoma acori tatarinowii could significantly reduce the serum methylglyoxal and the percentage of neuron apoptosis. Conclusion: Polygala tenuifolia and rhizoma acori tatarinowii could improve diabetes mellitus rat's cognitive impairment by reducing serum methylglyoxal.
