溶血性贫血患儿葡萄糖-6-磷酸脱氢酶检测

葡萄糖-6-磷酸脱氢酶(Glucose-6-phosphate dehyrdrogenase，G6PD)缺陷症在我国主要见于长江流域及其以南各省，以四川、广东、广西、云南、福建、海南等省(自治区)的发病率较高，北方各省(自治区)较为少见。G6PD的缺乏可以导致急性溶血性疾病，其主要临床表现为黄疸、贫血及血红蛋白尿。本病易发于幼儿及儿童。新生儿的G6PD缺乏率为3．0％-

家兔人工感染人源贾第虫的实验研究

蓝氏贾第鞭毛虫在全世界分布广泛[1],我国人群感染率也较高[2],尤其是儿童.该虫引起的贾第虫病的危害性正逐步受到重视,对其深人研究有赖于动物模型的建立.国内外学者先后建立了人源蓝氏贾第鞭毛虫的长爪沙鼠[3,4]、B细胞缺陷小鼠[5] 、C57BL/6N小鼠[6]、家猫[7]和家犬[8]等感染模型,家兔实验感染蓝氏贾第鞭毛虫的研究尚未见报道.该研究用人源贾第虫人工感染家兔,观察了其病理变化、滋养体分布和排囊规律,摸索出提高感染成功率的方法.     

白细胞三烯病理生理学受体生物学和受体拮抗剂

白细胞三烯(Leukotrienes,LT)C4、D_4和E_4是一组花生四烯酸5-脂氧酶途径的代谢产物,其理化性质和生物活性与过敏性慢反应物质(SRS-A)相似。因此,目前都认为SRS-A就是三者的混合物。LTC_4、LTD_4和LTE_4的化学结构已于八十年代早期被证明,其后进行了人工合成,大大推进了对它的研究工作。有关LT在炎症和过敏反应中的重要作用已有许多综述,本文将重点讨论LT在呼吸、心血管和肾脏病生理方面的作用和有关LT受体性质、传导机理以及拮抗剂的发展。     

The correlation between TNF-α, IL-6 in cervical mucous during follicular development and ovulation stimulation in different protocols

Objective To investigate the correlation between TNF-α and IL-6 levels in cervical mucous during follicular development and ovulation stimulation in different protocols.Methods 36 infertile women were set up as experimental groups,divided into CC, HMG, IVF-ET group,each group consisted of 12 infertile women and 15 women with normal menstrual cycles were choiced as control group.Cervical mucous during follicular phase, luteal phase and ovulation phase were collected.TNF-α, IL-6 levels in cervical mucous were measured by radioimmunology assay (RIA).Follicular development were monitored by transvaginal ultrasonagraphy.Results (1) TNF-α levels in cervical mucous of experimental groups and control group were periodically various among the reproductive cycle.It increased during follicular phase, reached to peak during ovulation phase, and decreased during luteal phase (P＜0.05).IL-6 levels had no obvious periodical changes.(2) Compared with CC and control group, levels of TNF-α,IL-6 in HMG and IVF-ET group were significantly higher (P＜0.05).(3) Levels of TNF-α and IL-6 in cervical mucous were positively correlated with the dominant follicle diameter (r=0.261, r=0.192 respectively,P＜0.05).(4) TNF-α and IL-6 showed positive correlation in the reproductive cycle (r=0.782,P＜0.05).Conclusions (1) TNF-α level shows a cyclic change in the reproductive cycle and peaks during ovulation,whereas IL-6 level does not.(2) TNF-α and IL-6 may play a certain role in the process of follicular development and ovulation.(3)The levels of TNF-α and IL-6 are up-regulated by gonadotrophic hormone.(4) TNF-α and IL-6 may have coordination properties and participate in the same biological effects.     

地榆升白片治疗抗甲状腺药物致白细胞减少32例

Graves病在应用抗甲状腺药物治疗时,常见不良反应是白细胞减少症,严重时可有0.1%～0.5%的患者出现粒细胞减少,多在服药的前2～3个月内,当白细胞降至3×109/L以下或粒细胞总数降至1.5×10 9/L以下时停用抗甲状腺药物,将影响甲亢的治疗和预后[1].笔者应用地榆升白片治疗抗甲状腺药物所致的反应性白细胞减少症和粒细胞缺乏症32例,获得满意疗效,现将结果报道如下.     

白藜芦醇对C6鼠胶质瘤细胞抑制生长和诱导凋亡的作用

白藜芦醇（resveratrol，Res）是一种广泛存在于植物中的植物补体，Res不但可以作为一种抗氧化剂，有防治心血管疾病的功效。而且具有抗炎和抗癌的作用，它可以在肿瘤的起始、发生、进展等各个阶段通过多种途径起到抑制肿瘤的作用。近年来有关胶质瘤的大量研究证实，表皮生长因子受体（epidermal growth factor receptor，EGFR）的基因扩增和过表达是恶性胶质瘤发生、发展的重要始动事件之一，其介导的信号转导通路发挥着关键的作用旧J。本实验进一步就Res对C6鼠脑胶质瘤细胞生长增殖的抑制、诱导细胞凋亡及其与胶质瘤增殖、凋亡相关的EGFR等重要基因变化进行了探讨。
