This prospective observational study aimed to assess ovarian reserve after three different methods for induction of ovulation in 60 women between 30 and 40 years old with polycystic ovary syndrome. Women were equally divided into three groups. Group I included women who responded to clomiphene citrate. Women enrolled in groups II and III were subjected to either unilateral or bilateral ovarian drilling, respectively. Ovarian reserve testing was performed once before and three months after treatment. Basal serum inhibin B level showed a significant decrease after bilateral drilling compared with predrilling level (53.8 +/- 13.5 vs 46.3 +/- 6.2 pg/mL; P= 0.031). The antral follicle counts and summed ovarian volume showed a significant decrease after bilateral drilling (16.5 +/- 1.3 vs 14.9 +/- 2.1; P= 0.007 and 11.5 +/- 1.0 vs 10.3 +/- 1.1/mm3; P= 0.001). We concluded that diminished ovarian reserve may occur after bilateral ovarian drilling but not after clomiphene citrate induction of ovulation or unilateral drilling. 相似文献

Clinical and neuropathological features of a case of subacute necrotizing encephalomyelopathy are discussed and compared with the features of central pontine myelinolysis. A hypothesis is offered relating the two diseases to a common aetiological factor. 相似文献

Right middle lobe collapse as a result of endobronchial involvement with Wegener''s granulomatosis is reported in a 60-year-old woman. A review of the literature has revealed 6 cases of lobar collapse, only 2 of which had endobronchial disease. 相似文献

A series of compounds structurally related to the carcinogen and mutagen 5-methylchrysene (1) was synthesized and tested for mutagenicity toward S. typhimurium TA 100. The compounds prepared were 5,11-dimethylchrysene (2), 5-(hydroxymethyl)chrysene (3), 5-(acetoxymethyl)chrysene (4), 5-carbomethoxychrysene (5), 5-(hydroxymethyl)-1,2,3,4-tetrahydrochrysene (6), 5-carbomethoxy-1,2,3,4-tetrahydrochrysene (7), and 5H-chryseno[4,5-bcd]pyran-5-one (31). When tested in the presence of rat liver homogenate, 1 and 2 were active while 3--7 were less mutagenic than 1; 31 was highly mutagenic. The mutagenicity of 1 and 2 contrasts with the low activity of 5,12-dimethylchrysene, which supports the generalization that the structural requirements favoring activity are a bay-region methyl group and a free peri position, both adjacent to an unsubstituted angular ring. The low activity of 3--7 indicates that methyl oxidation is not an important activation process for 1. This agrees with previous studies in which the major proximate mutagen and carcinogen of 1 was identified as 1,2-dihydro-1,2-dihydroxy-5-methylchrysene. 相似文献
