1) Sialidase; Bacterial vaginosis; Premature rupture of membranes; Premature delivery; Newborn infection.

2) Methods From 2000 to 2001, The results of sialidase activity of vaginal secretions were compared with that of 4 traditional diadynamic criterias for bacterial vaginosis in 312 outpatients.

3) Objective To investigate the value of the sialidase activity of vaginal secretions in bacterial vaginosis diagnosis.

4) Objective: To determine sialidase activity in human hepatocellular carcinoma(HCC) so as to probe into the mechanism of gangliosides change(GD3 increasing)in HCC.

5) Methods The results of sialidase activity of vaginal secretions were contrasted with that of Gram stained smears examination for clue cells,(http:///sialidase.html) and that of routine examination.

6) The present invention also comprises therapeutic compositions having sialidase activity, including protein-based compounds having sialidase catalytic domains.

7) Objective To evaluate the shape and features of pathogens in bacterial vaginosis(BV) calibrated and differentiated by the method of sialidase so as to improve BV diagnosis.

8) AIM:To explore the effects and mechanisms of human membrane associated sialidase (NEU3) on apoptosis of PC3 cells induced by vitamin K3 (VK3).

9) The complication of infection of candida vagitis and trichomonas showed no marked effect of the activity of sialidase test.

10) We have investigated the effects of ethanol exposure in utero on the content of sialic acid and sialidase activity in newborn rat brain.

11) Conclusion: The increase of ganglioside GD3 in HCC is not only due to the enhancement of GD3 synthase activity, but also due to the decrease of the sialidase activity.

12) Results There was close correlation between the results of sialidase activity of vaginal secretions and that of 4 traditional diadynamic criterias.
