普洱茶对被动吸烟小鼠生长性能和血液指标的影响

本文研究普洱茶对被动吸烟小鼠生长性能和血液指标的影响。180只小鼠分为3组，空白组不吸烟、灌服生理盐水；试验Ⅰ组吸烟、灌服生理盐水；试验Ⅱ组吸烟、灌服普洱茶。饲养周期35d。试验Ⅰ组小鼠末体重和平均日增重显著低于（P < 0.05）试验II组，试验II组低于（P < 0.05）空白组。血红蛋白浓度和碳氧血红蛋白浓度，空白组和试验II组差异不显著，显著小于（P < 0.05）试验I组；红细胞平均血红蛋白浓度，试验组Ⅰ和II差异不显著，显著高于（P < 0.05）空白组。本试验结果证明，普洱茶可以显著改善被动吸烟小鼠生长性能和红细胞载氧功能，缓解烟毒危害。

Effects of Oral Administration of Pu'er Tea Extracts on Growth Performance and Blood Parameters in Passive Smoking Mice

The objective of this study was to determine the effects of oral administration of Pu’er tea extracts on growth performance and blood parameters in passive smoking mice. One hundred and eighty ICR mice were assigned randomly to one of three treatments with 10 mice per group. The control group orally administered physiological saline, groupⅠorally administered physiological saline and received cigarette smoking, and group Ⅱ orally administered Pu’er tea extracts and received cigarette smoking. After 35 d of this experiment, growth performance and blood parameters were analysized. The final body weight and average daily gain of group Ⅰ mice were lower (P < 0.05) than those of group Ⅱ, and group Ⅱ lower (P < 0.05) control group. The serum hemoglobin and carboxyhemoglobin concentrations of control group and group Ⅱ were no significant difference, but were lower (P < 0.05) than those of group Ⅰ. The hemoglobin concentrations of group Ⅰ and Ⅱ in serum red cell were no significant difference, but were higher (P < 0.05) than those of control group. The findings of this study showed that oral administration of Pu’er tea extracts could improve the growth performance and the capability of oxygen carry in passive smoking mice.
