METHODS: Two sets of animal experiments were performed in the present study. Forty New Zealand rabbits and 48 Sprague-Dawley (SD) rats were assigned randomly to one of the five groups: sham adhesion, adhesion with saline, adhesion with low dosage of the CT, adhesion with middle dosage of the CT and adhesion with high dosage of the CT. t-PA and PAI activity in plasma, OHP and TGF-β1 expression in adhesion were investigated. Analysis of variance was used to test differences among groups. RESULTS: CT treatment increased plasma t-PA activity in rabbits but decreased TGF-β1 activity in rats. The data were expressed from low to high dose respectively as follows: t-PA, 46.1±8.6 μkat/L, 59.6±10.1 μkat/L, 64.0±11.5 μkat/L; TGF-β1 28±7.23%, 31±3.05%, 30±4.04%. There were significant differences compared with saline-treated animals (t-PA 26.4±5.1 μkat/L, TGF-β1 54±5.51%). OHP content in cecum of rabbits from middle and high but not low dose of CT lowered significantly as compared with saline-treated rabbits, 0.3641±0.1373, 0.3348±0.0321, 0.2757±0.0497 mg/g vs 0.4183±0.0883 mg/g of protein, P>0.05, P<0.05, P<0.05 respectively. The rabbit plasma PAI activity and OHP content in abdominal wall had no difference in all groups. CONCLUSION: CT treatment significantly enhanced t-PA activity in rabbits, but decreased TGF-β1 content in rats, OHP content in cecum of rabbits, and failed to affect the activity of PAI and OHP content in abdominal wall in rabbits, compared with saline group. The result suggests that CT could effectively prevent adhesions without interfering wound healina.展开更多

Methods: The total of 396 patients who had received abdominal operation were randomly divided into the treated group (188 cases) and the control group (208 cases). Same treatment was given to both groups except that the treated group received TZM orally or via nasogastric tube. The time of borborygmus recovering and first passing of flatus defecation after operation was recorded. Patients’ gastro intestinal motility was observed by isotope tracing with I 131 capsule. The frequency and intensity of borborygmus were measured by a tracer. All patients had been followed up for 2-3 years. Results: The recovery of borborygmus, the first passing of flatus defecation were much earlier, the I 131 capsule passed gastro intestinal tract more quickly, and the tracer showed higher frequency and intensity of borborygmus in the treated group than those in the control group. Follow up study also showed the treated group was better than the control group in the non adhesion rate and the total effective rate ( P <0.05). Conclusion: TZM has good effect on stimulating postoperational gastro intestinal peristalsis and preventing the occurrence of postoperational intestinal adhesion.展开更多
