高原环境下大鼠对硒制剂耐受力的实验研究

本实验将大鼠从上海空运至兰州，很快转至高海拔地区，用光镜及电镜观察了亚硒酸钠对大鼠的影响。结果发现在高原环境下大鼠对硒的耐受力减低，引起了大鼠猝死半加得高原缺氧对心肌的损伤，降低了大鼠高原适应性。本文还对其耐受机理进行了初步讨论。     

人体液中喷布洛尔及其代谢物的GC/MS分析

用气相色谱一质谱联用(GC-MSD)系统分析方法检出了人尿中喷布洛尔的6个羟化代谢物,用Scp-Pak柱提取的方法检出了人血浆中的原型药物。并从分子结构上对此药物的代谢途径进行了研究。尿中提取和血中提取的回收率分别为90.83.%和85.88%,Gc-MSD的检测限为5pg。本方法适用于运动员兴奋剂的系统检查。     

改良锂清除试验──一种在人体测量肾小管钠转运功能的方法

在常用的七小时锂清除试验方法基础上，我们观察了实验开始后第四小时血清理浓度与血清理代表浓度的关系，二者密切相关，ｙ＝０．９０９ｘ＋０．１７，ｒ＝０．９５２，Ｐ＜０．００５。应用此方程式，可将原方案中两次取血减为一次。另外，我们还总结出正常人锂清除率和锂排泄分数的参照值分别为８．４～３１．６ｍｌ／ｍｉｎ和９．６％～２６．３％。     

Corticotropin-Releasing Factor Reduces Lipopolysaccharide-Induced Pulmonary Vascular Leak

Previous studies have suggested that corticotropin-releasing factor (CRF) has immunoregulatory effects in addition to its neuroendocrine role. We examined the ability of CRF to inhibit lipopolysaccharide (LPS)-induced pulmonary vascular leak in vivo. Female BALB/C mice were treated with either normal saline (NS) or CRF prior to injection with LPS. Pulmonary vascular leak was inhibited by CRF as assessed by measurement of lung wet-to-dry ratios. The stress-induced increase in serum corticosterone levels in mice injected with LPS alone was not further increased by treatment with CRF. This indicates that the effect of CRF was not mediated centrally by stimulation of endogenous steroid release. Histologic examination of the lungs revealed that leukocyte infiltration was significantly depressed in CRF-treated mice thus confirming the protective effect of CRF. In addition, a modest prolongation of survival was demonstrated in CRF-treated mice following challenge with LPS (p=.08). These data indicate the potential utility of CRF as a modulator of pulmonary vascular leak.

日晒海盐工人机体内高镁反应

报道福建某盐场从事日晒海盐生产人工机体内高镁对心血管系统的影响，通过现场空气、饮水、主良的镁含量测定，并对进入机体途径进行分析，得出空气、卤水接触、饮水为机体镁增高的主要来源。不同对象头发镁含量测定结果显示，以接触卤水、劳动强度大的盐工最高，并随机体内镁含量增高，出现血压偏低、心率减慢、心电图Ｐ－Ｒ间期延长、ＱＲＳ波增宽、Ｔ波高尖等机体高镁反应，与临床高镁血症相似。     

5105例乙肝三系统分布形式调查分析

本文对5105例乙肝三系统检测结果的32种组合形式出现率进行了统计分析,并引 入年龄因素分层分析。分析讨论了19岁以下、20～39岁、40～59岁及60岁以上四组受检者乙肝三系 统检测结果表现与分布的异同,并据此结合文献报道资料提出了预防处理意见。     

加强爱婴医院文化建设 促进母乳喂养

爱婴医院的文化氛围与爱婴医院的建立和发展密切相关。为搞好爱婴医院文化建设与管理,促进母乳喂养,本文对近几年发展起来的爱婴医院文化的构成、功能、特征和今后发展的标准进行了讨论。     

16例胸膜间皮瘤临床分析

１６例胸膜间皮瘤，其中１例有石棉接触史，占６．１７％；＞４０岁者占８１．５％。主要临床表现为胸痛、气短、咳嗽、低热和胸腔积液，临床上易误诊为结核性胸膜炎、肺癌胸膜转移等。胸部ｘ线检查及胸部ＣＴ对该病的诊断有帮助，大都有特征性表现。确诊靠针刺胸膜活检及开胸活检。胸膜间皮瘤的治疗主要采用手术、放疗和化疗，对于局限型治疗首选手术切除。肿瘤的良、恶性、疾病的分期及治疗与预后有一定关系。     

CT-guided stereotactic injection of radionuclide in treatment of brain tumors.

140 patients with brain tumor were treated by CT-guided stereotactic injections of radionuclides, such as Aurum-198 (198 Au), Phosphorus-32 (32 P) and Yttrium-90 (90Y). Of these patients aged from 3 to 67 years (average 37), 64 were male and 76 female. Astrocytoma was found in 75 patients, craniopharyngioma in 46, metastatic carcinoma in 7, meningioma in 5, germinoma in 4 and pituitary adenoma in 3. The tumors were located in the deep part or functionally critical area of the brain. After 267 times of injection of colloidal isotopes, no major adverse effects or complications occurred. Follow-up for 6 to 48 months showed improvement in symptoms in 104 (74.3%) patients and CT scanning showed the diminished tumors.
