溴氰菊酯对白纹伊蚊（Aedesalbopictus）C6／36细胞株的细胞遗传学效应

本研究选择１０μｇ／ｍｌ、２０μｇ／ｍｌ、４０μｇ／ｍｌ浓度的溴氰菊酯处理白纹伊蚊Ｃ６／３６细胞，以ＭＭＣ作为阳性对照物，观察溴氰菊酯处理２４ｈ后对Ｃ６／３６细胞染色体畸变率和姐妹染色单体互换（ＳＣＥ）频率的影响。结果显示，三个浓度的溴氰菊酯对Ｃ６／３６细胞染色体畸变率均没有显著影响（Ｐ＜０．０５）；溴氰菊酯浓度在４０μｇ／ｍｌ时可诱导Ｃ６／３６细胞ＳＣＥ频率轻度增高（Ｐ＞０．０５），而溴氰菊酯浓度在１０μｇ／ｍｌ、２０μｇ／ｍｌ时，对Ｃ６／３６细胞ＳＣＥ频率没有诱导作用。表明溴氰菊酯对Ｃ６／３６细胞的遗传学效应较弱

Clinical and hormonal effects of chronic gonadotropin-releasing hormone agonist treatment in polycystic ovarian disease

Previously, we reported that short term administration of a highly potent GnRH agonist (GnRHa) for 1 month to patients with polycystic ovarian disease (PCO) resulted in complete suppression of ovarian steroidogenesis without measurable effects on adrenal steroid production. This new study was designed to evaluate the effects of long term GnRHa administration in PCO patients with respect to their hormone secretion patterns and clinical responses. Eight PCO patients and 10 ovulatory women with endometriosis were treated daily with sc injections of [D-His6-(imBzl]),Pro9-NEt]GnRH (GnRHa; 100 micrograms) for 6 months. Their results were compared to hormone values in 8 women who had undergone bilateral oophorectomies. In response to GnRHa, PCO and ovulatory women had rises of serum LH at 1 month, after which it gradually declined to baseline. In both groups FSH secretion was suppressed throughout treatment. Serum estradiol, estrone, progesterone, 17-hydroxyprogesterone, androstenedione, and testosterone levels markedly decreased to values found in oophorectomized women by 1 month and remained low thereafter. In contrast, serum pregnenolone and 17-hydroxypregnenolone were partially suppressed, and dehydroepiandrosterone, dehydroepiandrosterone sulfate, and cortisol levels did not change. Clinically, hyperplastic endometrial histology in three PCO patients reverted to an inactive pattern, and proliferative endometrium in two other PCO patients became inactive in one and did not change in the other. Regression of proliferative endometrial histology occurred in all ovulatory women. Vaginal bleeding occurred in all women studied during the first month of GnRHa administration, after which all but one PCO patient became amenorrheic. Hot flashes were noted by all ovulatory women and by four of eight PCO patients. All PCO patients noted subjective reduction of skin oiliness, and five had decreased hair growth. We conclude that in premenopausal women: 1) chronic GnRHa administration results in apparently complete persistent suppression of ovarian steroid secretion; 2) adrenal steroid secretion is not influenced directly or indirectly; and 3) its use may be helpful in the treatment of endometrial hyperplasia and ovarian androgen excess in women with PCO.     

复方华蟾胶囊抗小鼠肿中瘤作用的实验研究

目的了解复方华蟾胶囊抗小鼠移植性肿瘤的作用.方法以小鼠肝癌22(H22)、小鼠肉瘤180(S180)为瘤株,应用动物移植性肿瘤的体内试验法对药物进行抗癌药效学试验.结果复方华蟾胶囊灌胃4,2 g/kg@d,连续14 d,对小鼠移植性肝癌实体型生长有明显的抑制作用,抑瘤率分别为38.09%,30.95%.对小鼠移植性S180实体型生长有明显的抑制作用,抑瘤率分别为34.7%,30.08%.复方华蟾胶囊对荷瘤小鼠的胸腺和脾脏重量无影响.结论复方华蟾胶囊在试验条件下有一定抗肿瘤作用.     

类保幼激素对三带喙库蚊幼期发育的影响

本文报告用亚致死剂量的 S—31183(类保幼激素)处理三带喙库蚊幼虫对其发育影响的研究,结果表明处理后蛹期死亡率明显高于幼虫期,并且与剂量大小有关。S—31183处理幼虫并不影响幼虫的发育时间,但可使幼虫化蛹时蜕皮受阻与羽化受到一定的抑制。     

X综合征的临床诊断与分析

目的；探讨临床医师对X综合征的临床诊断水平并了解其发病机制；方法：对186例有胸痛的女性患者（平均年龄53.2岁）通过运动试验，左室功能及冠状动脉造影来评估X综合征患者冠脉微循环功能及发病机制；结果：186例中86人（46％）冠脉造影阴性，运动试验阳性，左室功能无明显失调；结论：X综合征多见于女性，X综合征可能是由于冠脉微血管功能异常所致。
