Study on the Formation of Novel Threadlike Structure through Intravenous Injection of Heparin in Rats and Refined Observation in Minipigs.

ABSTRACT: Objective. To study if the novel threadlike structure (NTS) was caused by coagulation during injecting urethane intraperitoneally and the source of NTS. Methods. Twenty-two SD rats were anaesthetized by urethane injected intraperitoneally. Heparin was injected at 5 minutes before the anaesthesia from femoral vein in 11 rats, and saline was given in the other 11 rats randomly. Six Chinese minipigs were carried to look for NTS. One sample was taken to be stained by DAPI/Phalloidin and observed by a laser scanning confocal microscope. Results. In the group of heparin, 10 rats were found to have NTS with appearance rate of 90.9%, and 9 rats were found to have NTS with the appearance rate of 80.1%. Both groups have 1.81 average numbers of NTS in each rat without significant difference (P > 0.05
