The treatment comparison by using Chinese TANG Kidney capsule and Western medicine TANG SHI PIN showed: the kidney capsule can lower the values of the blood sugar, blood fat, series of micro-protein un urine and carbon monoxide in plasma, thus the function of kidney can be improved, and prolong the process of deadness and hardening of the affected kidney small cell fibre.

利用该模型选择中药糖肾胶囊与西药糖适平对照治疗研究，结果显示：糖肾胶囊能降低糖尿病肾病大鼠的血糖、血脂、尿素氮、肌酐、尿系列微量蛋白及血一氧化氮等指标，从而减轻糖尿病肾病大鼠肾小球的高灌注高滤过，降低糖化血红蛋白含量，减轻非酶糖基化，改善肾功能，降低血脂、内皮素、调节血栓素、前列腺素水平，有抗脂质过氧化损伤的作用。

These parameters did not differ from each other in figleaf gourd"s two treatments. The root temperature of 14℃didn"t induce significant changes in the total respiration rate in both species but caused an increase of the alternative respiration pathway and a decrease of the cytochrome respiration pathway, and more dead cells in root tips in cold-sensitive cucumber roots.

低温条件下，黄瓜的生长明显差于黑籽南瓜，同时根系表现出更高的超氧化物阴离子O_2~(·-产生速率、过氧化氢(H_2O_2)与膜脂过氧化产物丙二醛含量以及抗氧化酶活性。14℃根温并未引起两种作物根系的总呼吸速率发生变化，但却引起黄瓜根系的交替途径呼吸速率与细胞色素途径呼吸速率的显著变化，表现为低温下Valt的上调而Vcyt的下降。
