There were significant difference in phagocytic activity,SOD activity and bactericidal activity(P<0.01) in the 400, 500,and 600 mg/kg groups compared with the control group. In the 250 and,1000 mg/kg,however,there were significant difference in bactericidal activity(P<0.05).
2. The bactericidal activity of platelet PLA2 was influenced by pH in media, and the bactericidal rates of PLA2 were 44.4%, 99.8% and 99.5% respectively in the pH of 5.0,7.4 and 9.0. It was easy for the PLA2 to be combined with serum albumin and its bactericidal activity is affected by serum albumin in media.
②Among of the acid stressed juvenile turtles,the phagocytic rate of blood cell,serum bacteriolytic activity,bactericidal activity and level of complement C3 in Ⅰ-Ⅳ were significantly higher than that in C,and Ⅳ was significantly higher than the other four groups.
Serum bactericidal activity and level of complement C3 in the four groups of experiment Ⅰ-Ⅳ were significantly higher than control group, and experiment Ⅳ group significantly was higher than the other 4 groups.
The blood in turtles were collected,and the percentage phagocytic rate of blood cell was analyzed by counting under microscope; serum bacteriolytic activity,bactericidal activity,levels of complement C3 and C4 were analyzed by transmission colorimetric method.
ZAHS had been neutralized in tube with antiserum against human C 3 and C 5. Results In 0.07 0.09 ml ZAHS and 1 3h, intracellular bactericidal activity (ICBA) showed a peak but significant top value at 2nd hour.
Sixty-eight samples of venous blood were collected from 41 patients with either single or multiple fracture and the level of intracellular bactericidal activity(ICBA),superoxide free ions)and specific granules(SG)in the isolated polymorphonuclear neutrophils(PMNs)were determined.
Results After anti human BPI polycolonal antibodies or monoclonal antibodies having no bactericidal activities were added, bactericidal rate of porcine BPI increased. But the antibody not against BPI had no such improving bactericidal activity.
Compound 4b exhibited bactericidal activity agains S.
The compounds 3c, 3d, and 3g showed certain bactericidal activity against E.
coli; while compound 3g showed certain bactericidal activity against P.
The plants of the families Geraniaceae and Rosaceae offer promise as a source of raw material for isolation of polyphenolic compounds exhibiting bactericidal activity, including against opportunistic pathogens (B.
