These results indicate that menstrual blood loss does not affect the complete blood count and suggest that granulocyte-colony stimulating factor plays and important role in the mechanism of ovulation.

We investigated the relationships between tumor necrosis factor (TNF) gene polymorphism, circulating TNF-alpha (TNF-alpha) concentrations, and bone mineral density (BMD) in the lumbar spine. TNF gene polymorphisms studied were the Nco I polymorphism within the first intron of TNF-beta (TNF-beta) and three single nucleotide polymorphisms in the promoter region of the TNF-alpha gene, at positions -857, -863, and -1031. Allelic variants of the TNF gene were identified using restriction fragment length polymorphism (RFLP) analysis in 177 postmenopausal Japanese women within 10 years after menopause, aged 56.4 +/- 4.5 years (mean +/- SD). A significantly higher prevalence of the alleles TNF-alpha-863A (20.3% versus 9.9%) and TNF-alpha-1031C (21.3% versus 12.4%) was seen in the low BMD group (Z-score < 0, n = 91) than in the high BMD group (0 < Z-score, n = 86). In genotype analysis, although difference did not reach a significant level, women with the rarest allelic variants, i.e., homozygous TNFbl, TNF-alpha-863A, and TNF-alpha-1031C, showed the lowest BMD Z-scores. Women with another rarest allelic variant, TNF-alpha-857T/T had significantly lower BMD Z-scores than did women with TNF-alpha-857C/T or -857C/C. The BMD Z-score decreased significantly with an increase in the total number of such rare alleles. Serum concentrations of TNF-alpha did not differ significantly among groups divided by genotypes. Multiple linear regression analysis revealed that the total number of rare alleles, in addition to the body mass index and the number of years since menopause, was an independent predictor of the BMD. These presumptive functional polymorphisms of the TNF gene may be associated with the lumbar spine BMD in early postmenopausal Japanese women.

Antibiotics, especially cephems, have been improved remarkably in the last 20 years. In order to evaluate the improvement of antibiotics used for the prophylaxis of infections after radical hysterectomy, two groups of patients (group A, 1978–1979, n = 54; group B, 1985–1987, n = 55) were examined in regard to bacteriological and clinical effects. In spite of the improvement of antibiotics, the positive rate of bacteriological analysis had increased from 44.4 to 76.4%. Obvious decrease of gram-negative bacilli and increase of gram-positive cocci (GPC), e.g. Enterococcus, were observed. In contrast, fever index and febrile morbidity of group B decreased significantly more than those of group A. These results indicate that the improvement of antibiotics has brought more effective prophylaxis in the postoperative infection in spite of the high positive rate of GPC.
