[Detection the serum IgM and IgG specific for TORCH in 1307 women in the period of pre-pregnancy and pregnancy].

OBJECTIVE: The objective is to obtain the information of women in the period of prepregnancy and pregnancy infected by TORCH (Toxoplasma, Rabella Virus, Cytomegalovirus, and Herpes Simplex Virus) in Kunming for preventing fetus from infection by TORCH in uterus. METHODS: The serum IgM and IgG specific for TORCH from 1307 women in the period of pre-pregnancy and pregnancy were measured with ELISA and The reagent is the product of virion/serion. RESULTS: The serum IgM specific for TORCH were detected in 2.83% of 1307 pregnant women for Toxoplasma, 2.37% for Rebulla Virus, 0.46% for Cytomegalovirus, 2.45% for Herpes Simplex Virus. The total positive rate of serum IgM specific for TORCH was 1.45%. The serum IgG specific for TORCH were detected in 3.98% of 1307 pregnant women for Toxoplasma, 72.3% for Rebulla Virus, 97.78% for Cytomegalovirus, 80.34% for Herpes Simplex Virus. The total positive rate of serum IgG specific for TORCH was 63.60%. There was no significant difference among the women with different pregnant situation in terms of the serum IgM and IgG specific for TORCH. CONCLUSION: There are some of women in the period of pre-pregnancy and pregnancy with current infection by TORCH in Kunming. It is recommended to screen for infection by TORCH in women in the period of pre-pregnancy and pregnancy to prevent fetus from infection by TORCH in uterus.

[Alleles of HLA class II DRB1 of patients with essential hypertension in Yunnan Hans].

OBJECTIVE: To investigate the association between the alleles of human leukocyte antigens (HLA)-DRB1 and essential hypertension (EH) in the Hans living in Yunnan of China. METHODS: The alleles of HLA-DRB1 were typed by polymerase chain reaction-sequence specific primers (PCR-SSP) technique in samples from 83 patients with essential hypertension and 91 healthy controls. All of the subjects, their grandparents and grand-grandparents are Hans living in Yunnan of China. RESULTS: The frequency of DRB1*1501/2 in the EH patients (0.219) was significantly higher than that in the controls(0.060), chi quare=18.331, P<0.01. Relative risk (RR) was 4.46, and etiologic factor (EF) was 0.34. The frequency of DRB1*0901 significantly decreased in the group of patients with EH in comparison to the controls (0.081 versus 0.192) chi-square=8.704 P<0.05. RR was 0.41 and prevention factor(PF) was 0.19. CONCLUSION: HLA-DRB1*1501/2 is associated with the susceptibility to essential hypertension in the Yunnan Hans of China. DRB1*0901 may protect one from the disease.
