青少年高血压的研究进展

随着人们生活和行为方式的改变,高血压发病明显呈年轻化趋势。在青少年时期识别高血压病高危人群有助于早期进行有效干预和治疗,降低未来高血压的发生率及其严重性。现试从青少年高血压的诊断、发病因素、特点、治疗策略等方面的研究进展作一综述。     

Pulmonary sporotrichosis in Oklahoma in susceptibilities in vitro

Six cases of pulmonary sporotichosis were observed in 2 institutions in Oklahoma City, Okla. Three of the patients were treated with iodides with or without surgery. Although one patient required a second course of iodides, the patients have remained well after at least 34 months of follow-up. Three patients treated with amphotericin B, single course as well as multiple courses, and other antifungal agents (hydroxystilbamidine and miconazole) have all relapsed. These cases and a reviewed of more than 40 cases of pulmonary sporotrichosis susceptibilities of Sporothrix schenckii that we observed in vitro suggest that amphotericin B is not an effective agent for the treatment of pulmonary sporotrichosis. It is our opinion that the treatment of choice for pulmonary sporotrichosis is a supersaturated solution of potassium iodide. If the patient is allergic to the medication or fails to respond, then a combination of amphotericin B plus flucytosine may be tried.     

Morbidity in cardiovascular diseases in immigrants in Sweden

INTRODUCTION: Although immigration to Sweden has increased in the last few decades, the incidence rates of cardiovascular disease and coronary heart disease in immigrants are unknown. The aim of the present study is to estimate whether place of birth affects the incidence rates of cardiovascular disease and coronary heart disease. MATERIAL AND METHODS: The study was designed as a follow-up study on morbidity in cardiovascular disease and coronary heart disease between 1 January 1997 and 31 December 1998, including three and a half million persons with age range 35-64 years, of whom 550 000 were born abroad, from the database MigMed consisting of the whole Swedish population. Incidence rates and relative risks were estimated by indirect standardization and a proportional hazard model. RESULTS: The age-adjusted risk of coronary heart disease was higher in most foreign-born groups than in Swedes. For example, in nine of 12 male groups, the relative risks varied between 1.1 and 2.2, and in seven of 12 female groups, the relative risks varied between 1.4 and 2.5. When also adjusting for level of education and employment status, the risks were still high, but on a lower level. CONCLUSIONS: Foreign-born people possess an over-risk of cardiovascular or coronary heart disease(CVD/CHD) compared with Swedish-born persons, also when level of education and employment status are taken into account.     

C·肉毒杀鼠素(冻干剂)应用研究

目的为研究C·肉毒杀鼠索对杀灭达乌尔黄鼠(简称黄鼠)的大面积应用情况和对家畜、家禽的毒害作用,进行了C·肉毒杀鼠素的应用研究.方法大面积投毒采用ES-2药饵撒播机[1],间隔约80m进行条投.羊、鸡采用直接灌胃.结果大面积应用的灭鼠率为83.72%.对羊、鸡最高剂量分别为500万MLD、150万MLD,均未出现中毒现象.结论 C·肉毒杀鼠素是较为理想的草原大面积杀灭黄鼠的理想、首选药物.     

近年来我国神经病学的进展

建国50年来,尤其是近十余年来,我国在神经病学研究方面取得了长足进步。由于篇幅所限,只能涉及主要的几个方面。重症肌无力一、糖皮质激素受体重症肌无力患者在用肾上腺糖皮质激素治疗前,其外周血白细胞糖皮质激素受体位点数(结合位点/细胞)与正常对照组相比报道不一,有低有高。而其血浆皮质醇浓度正常。治疗前糖皮质激素受体位点数高者疗效较好。经糖皮质激素治疗后,糖皮质激素受体位点数较治疗前下降。其周围血单个核细胞糖皮质激素受体低不是由于周围血中有抑制因子,而是由于糖皮质激素受体ｍＲＮＡ转录和(或)蛋白翻译水平有障碍。二、重…
