茶多酚、茶多糖对兔动脉血压的影响

Affection of the Tea-polyphenls and Tea-polysaccharide on Arterial blood Pressure in Rabbit

兔静脉注10mg/mL的茶多酚和茶多糖溶液,观察对动脉血压的影响,结果表明:注射茶多酚1～3mL后收缩压6次降低(9%～20%),2次升高(13%和20%),3次无变化;舒张压2次升高(20%和140%),9次无变化;注射茶多糖1～4mL后收缩压9次降低(2%～29%),3次升高(13%～40%),5次无变化;舒张压4次降低(10%～200%),7次升高(20%～50%),6次无变化。上述浓度和剂量的茶多酚、茶多糖对兔动脉血压均无显著影响(P>0.05～0.5)。

The tea- polyphenls and tea- polysaccharide（10mg/ml） were inv. to narcotic rabbit an observation was made on the change of arterial blood pressure. The results were shown as follows：after injecting tea - polyphenls with dose 1 - 3ml ,the systdic pressurewas reduced 6 times and rised 2 times and 3 times observed no change,the diastolic pressure was rised 2 times and 9 times were no change. After injecting tea - polysaccharide with dose 1 -4ml,the systdic pressure was reduced 9 times and rised 3 times and 5 times observed no change,the diastolic pressure was reduced 4 times and was rised 7 times and 6 times no change. Concentration and dosage change of the tea- polyphenls and tea- polysaccharide didn, t show marked influence on arterial blood pressure in rabbit（ P 〉 0.05 - 0.5） ,there was no marked difference in 3 doses（ P 〉0.05）.
