Objective To study the current situation of diagnosis and treatment of rudimentary uterine horn pregnancy through 4-cases report. Methods We made a clinical study of 4 cases of rudimentary uterine horn pregnancy admitted to our hospital between 1995 and 2005. Results Three patients had been undergone artificial abortion before they were admitted to our hospital. All the patients were asymptomatic. Ultrasonography was made in 3 cases. Two cases were diagnosed as rudimentary uterine horn pregnancy. Three patients were cured with surgery. Conclusions Rudimentary uterine horn pregnancy is rare and with atypical clinical manifestation in the first trimester. Although diagnosis before surgery is difficult, ultrasonography and MRI make a great role. Surgery is the most important therapeutic method.
5.Effect of concanavalin A on mouse islet transplantation
Chinese Journal of Pathophysiology 1986;0(01):-
To test whether Con A has antirejection effect on mouse islet allograft, 600-700 handpicked islets of C57BL/6 mice was transplanted beneath the kidney capsule of the streptozotocin induced diabetic BALB/C recipients. In control group the mean survival time (MST) of the grafts was 14.1?2.4 days. Treatment with Con A significantly prolong the MST of the islet allografts. In group with Con A treatment of the donor islets prior to the transplantation the MST was 25?5.4 days. The MST increased sigificantly after ip injection of Con A to recipient mice. The combined treatment of islet and recipient with Con A resulted in a prolongation of MST to 25.2?4.4 days. The experiments concerning the mechanisms of the antirejection effect of Con A showed that Con A was able to combine with the islet cell membrane well masking perhaps the histocmpatibility antigen. Furthermore the lymphocytes of mice after i. p Con A injection suppressed the lymphocyte proliferation reaction of the svnergic mice to mitogen.
