脑卒中的危险因素及其对策

在包括日本在内的发达国家，脑卒中的死亡率正在下降，但仍与恶性肿瘤和心脏疾病并列，成为主要死亡原因之一。脑卒中虽然不至于死亡，但成为躯体和智能障碍、卧床不起和痴呆的原因疾病。因此。预防脑卒中不仅是医学，还是社会的重要课题。为实现该目标，应正确了解日本人的脑卒中危险因素的状况。本文将以福冈县久山町的持续40年以上的流行病学调查（久山町研究）的结果为主介绍日本人的脑卒中危险因素。     

Analysis thrombolysis with anticoagulation treatment for early stage of deep vein thrombosis in the lower extremities

Objective:To explore the effect of thrombolysis with anticoagulation treatment forearly stage of deep vein thrombosis of lower extremity.Methods:The clinical data of 10 patients at the early stage of deep vein thrombosis(DVT)in the lower extremuites treated by thrombolysis with anticoagulation and dispersion drugs were analyzed retrospectively.Results:The thrombolytic effect was significant.After treatment,the deep veins were recanalized without regurgitation in 75.3% of the patients.The total effective rate was 100%.Only three patients had hemorrhagic complication,but none of the patients died.Conclusion:Thrombolysis with anticoagulation treatment is an effective and safe method for DVT at the early stage.     

铁代谢与肝癌预防

铁离子是人体中含量最大的金属元素，主要作为红细胞内的血红蛋白铁和肌肉中的肌红蛋白铁而从事分子氧的运输作用。它还存在于一切细胞之中，催化细胞内的氧化还原而形成多数的酶活性中心，并与细胞生长和凋亡等机制相关。铁离子如果在体内存在过剩，则其毒     

An experimental study of spinal cord evoked potential.

The characteristics of spinal cord-evoked potentials were investigated by using an in vitro spinal cord preparation. The spinal cord isolated from adult rats was immersed in a bathing chamber filled with oxygenated artificial cerebrospinal fluid (aCSF). The spinal cord-evoked potentials elicited by the stimulation of the spinal cord were recorded by using bipolar platinum electrodes. The potentials recorded consisted of early and late negative components (N1, N2). The inhibitory effect of lowered temperature on the N1 potential was clearly demonstrated. The oxygen deprivation of aCSF showed the higher sensitivity of N2 potential to hypoxia than that of N1. It was also possible to analyze the effects of potassium and magnesium ion concentration and pH on the evoked potentials. These results showed that the pure effects of various physiological and chemical factors on the spinal cord-evoked potentials can be analyzed by this experimental model.

用肿瘤标记诊断恶性肿瘤

近年来关于肿瘤标记(marker)的研究已取得惊人的进展,目前已研制出利用瘤杂交技术制成单克隆抗体,对抗各种肿瘤抗原的单克隆抗体,具有很强的特异性,因     

颞骨及颅底肿瘤

颞骨病变的影象诊断,过去主要靠平片和多轨迹体层摄影。近年来,由于CT扫描技术的改进,空间分辨力已达0.1mm的高水平,已成为诊断方面的重要检查方法。最近磁共振也正在应用于临床。本文论述一下颞骨及颅底肿瘤主要病变的影象特征(包括磁共振)。一、颞骨肿瘤 (一)胆脂瘤胆脂瘤是锥体内发生的肿瘤。原发性胆脂瘤少见,它是由误入锥体的类上皮细胞发生的,继发性胆脂瘤发病率高,它是由慢性中耳炎引起的。在此论述继发性胆脂瘤的X线的表现。胆脂瘤的诊断,除因先天畸形看不到鼓膜外,     

名医之赞 “威达”之光——吴阶平副委员长考察威达医疗器械集团纪实

春节前夕,平时挺热闹的粤西山区县城——揭西,此刻显得出奇的静谧。1月23日上午,忽然大街上喇叭声声,几辆小车风驰电掣般驶入广东威达医疗器械集团公司的大门。 公司总经理刘之券早已等在大门口。车子一停,他立即箭步上前,双手握住了下车的那位风度翩翩的长者的手:“欢迎欢迎!终于把您盼来了!”     

土白蚁菌圃对大鼠睾丸组织的影响

本文报道用土白蚁菌圃２５５０、１１２５、５６２．５ｍｇ／ｋｇ喂养ｗｉｓｔａｒ大白鼠１４周，结果大鼠睾丸重量增加，曲细精管生精细胞旺盛，睾丸组织中ＤＮＡ含量升高，与对照组比较差异均有显著性意义。提示土白蚁菌圃有延缓动物衰老作用。
