在药理实验中，研究治疗肝脏疾病的药物需要观察给药后大鼠胆汁分泌情况。一般是在胆管上剪一“V”形开口，插入lmm粗的毛细玻璃管，结扎固定引流胆汁。由于毛细玻管极易折断，而且玻管也易划伤胆管，因此难以操作，有时影响实验速度和结果。为了解决这一问题，笔者在实践中改 In pharmacological experiments, the study of drugs for the treatment of liver disease need to observe the rat bile secretion after administration. Generally cut a “V” shaped opening in the bile duct, insert lmm thick capillary tube, ligation fixed drainage bile. As the capillary tube easily broken, and the glass tube is also easy to scratch the bile duct, it is difficult to operate, and sometimes affect the experimental speed and results. In order to solve this problem, I change in practice
