ABSTRACT
Objective To evaluate the significance of selective salpingography(SSG)and fallopian tube recanalization(FTR)in diagnosis and treatment for obstructive infertility.Methods Totally, 268women with infertility caused by obstruction of the fallopian tube were divided randomly into two groups, one (Group A)with a non-operative hysterosalpingeal system by insertion of co-axial cannula and guiding filament made by COOK Corporation in the US and another(Group B)with a self-prepared hysterosalpingeal system modified based on the apparatus of COOK Corporation, for SSG and FTR.Then, efficacy of SSG and FTR for the infertile women was evaluated by one-year cumulative pregnancy rate and reeanalization rate of the fallopian tube.Resnits One hundred and seventy of 198 fallopian tubes were recanalized in Group A, with a recanalization rate of 85.8%, and 290 of 320 tubes in Group B were recanalized.with a recanalization rate of 90.6%.reaching statistically significant difference.Furthermore, recanalization rate varied with different sites of occlusion of the fallopian tube.Pregnancy rate was 35.3%(36/102)in Group A, significantly higher than that in Group B(47.6%, 79/166).As the same, pregnancy rate varied with different sites of occlusion of the fallopian tube.Conclusion Selective salpingography and fallopian tube recanalization with self-prepared hysterosalpingeal system have dual effects on diagnosis and treatment for tubal infertility of women, which are simpler, safer and more reliable, worth to be clinically applied.
ABSTRACT
The experiment was performed at Basic Medical College and First Affiliated Hospital, Zhengzhou University from September 2004 to December 2005. Totally 60 Kunming mice were divided into 5 groups randomly: ①blank control group (n =15) and simple radiation group (n =15). The mice were given 0.2 mL sterile saline by intraperitoneal injection. ②antineoplastic polypeptide from Buthus Martensii Venom (APBMV) group (n =10) and APBMV plus radiation group (n =10) received 0.2 mL APBMV according to prepared concentration by intraperitoneal injection. ③Katsutoxin extract Ⅲ plus radiation group (n =10) received 0.2 mL katsutoxin extract Ⅲ by intraperitoneal injection every other 5.5 hours for 7 days. After 24 hours from the last injection, the mice were endured 60Co g ray radiation (80 cm, 7.5 Gy irradiation dose, 0.27 Gy/min dose rate). Then katsutoxin extract Ⅲ was given same as above for 7 days. Then bone marrow was extracted to be cultured to colony-forming unit-granulocyte and monocyte (CFU-GM). The findings showed that colony amount of APBMV plus radiation group and katsutoxin extract Ⅲ plus radiation group was obviously more than that of simple radiation group [(32?5),(27?3),(2?1)pieces/well,P
