RESUMEN
Objective To study previous cesarean section effects on re-eesarean section, and to seek better operation way of cesarean section. Methods The conditions of entrance into abdominal cavity and adhesion of 452 cases of abdominal cavity were retrospectively analyzed. The information about initial operation was investigated, dis-covering 104 cases underwent new type,and 348 cases underwent improved cesarean section. Results Time of en-trance into abdominal cavity once more by new type of cesarean section were (9.25±2.27) min and the incidence of adhesion in abdominal cavity was 18.27%,while time of entrance into abdominal cavity once more by improved cesarean section were (7.23±2.21) min and the incidence of adhesion indominal cavity was 9.87% (u=8.016, P<0.05; χ25.57,P<0.05). Conclusion New type of improved cesarean section has little effect on re-cesarean section, worthing more clinical practice.
RESUMEN
BALB/C mice were immunized by intraperitoneal injection with A-group erythrocytes, B-group erythrocytes and saliva of A-group,B-group secretor. Immune spleen cells were fused with sp2/0 murine myeloma cells. The supernatants from each well were examined for antibodies by hemagglutination using A-,B-, O-group RBC.3 hybridoma cell lines of secreting anti-A antibodies and 3 hybridoma cell lines of secreting anti-B antibodies were established.These hybridoma cells have maintained and produced antibodies possessing higher specificity and titer.The agglutination titer of supernatants reached 2048-fold. These antibodies were used in the field of forensic science.
