ABSTRACT
Objective:To investigate the expression of platelet-specific alloantibody in the sera of primipara,pluripara,and recurrent spontaneous abortion (RSA) patients,and analyze the relationship between platelet-specific alloantibody and gravidity or RSA. Methods:A total of 100 primipara, 100 pluripara (gravidity≥2) and 100 RSA patients who received prenatal examination in department of aristogenesis, No. 202 Hospital of PLA from Apr 2015 to Dec 2015 were recruited. The blood samples were collected during 16-28 weeks of pregnancy, and the expression of platelet-specific alloantibody was detected by solid-phase red cell adherence assay. Results:There were 5 positive platelet-specific alloantibody in primipara group, 14 in red all pluripara group,and 26 in RSA group. Platelet-specific alloantibody was significantly associated with gravidity and the incidence of RSA (P<0.05) by chi-square analysis. Conclusion:Screening the expression of platelet-specific alloantibody during pregnancy can provide evidence for the diagnosis and treatment of RSA.
ABSTRACT
Objective To investigate the effect of low intensity microwave exposure on the reproduction and offspring health of men. Method 424 married men operating radar constantly and 204 men as control were invited to complete the interview questionnaire on reproduction and offspring health. Results Incidence of abnormal sexual function in the radar group was 23.8%, while it was 14.7% in controls (P
ABSTRACT
Objective To study the changes in semen quality and levels of sex reproductive hormones in servicemen constantly exposed to radar. Method The quality of semen was analyzed with the aid of the WlTJ-9000 computer-assisted semen analysis system and the levels of sex hormones were determined with radioimmunoassay in 64 servicemen constantly exposed to radar. Results Compared to control group, semen volume, pH value, sperm density and sperm motility in radar-exposed persons were reduced. No significant difference was observed in semen viscosity, sperm viability rate, morphology, acrosomal integrity rate, and hormone levels between these two groups. Conclusions Microwave non-heating effect had adverse effect on the quality of semen, producing sub-clinical injuries.
