Ultrasound study of the spleen

The sonography is the method of choice for the determination of the size of the spleen. Normally, this has, represented from the left flank, a size of 12 x 5 cm (length and thickness) and a regular structural pattern. Splenomegalies with diffusely changed echo-structure are found in infections, congestion spleens as well as haemoblastoses. Focal lesions are typical for cysts, abscesses and haematomas of the spleen. The sonography of the spleen plays a particular role in the staging of malignant lymphomas, whereas metastatic changes of the spleen may more infrequently be stated sonographically. The authors deal with the great importance of the sonography of the spleen in abdominal traumas.     

蓝氏贾第鞭毛虫病毒研究进展

***自从1972年Mattern等[1,2]首次在溶组织阿米巴的某些虫株中发现病毒样粒子后,人们相继在阴道毛滴虫[3]、蓝氏贾第鞭毛虫(简称贾第虫)[4]、艾美尔球虫[5]、巴贝斯虫[6]及利什曼原虫[7]等原虫中发现特异性双链RNA病毒,目前原虫病毒已成为寄生虫学研究的热点。蓝氏贾第虫病毒(Giardia lam-bliavirus,GLV)是继阴道毛滴虫病毒发现后确认的第2个原虫病毒,GLV的发现为贾第虫病的诊断与防治、原虫与病毒及宿主间相互关系的研究提供了新的方向。1 GLV生物学特征1990年国际病毒分类命名委员会将GLV正式归入单组分双链RNA球状真菌病毒科(To…     

Anatomical study of the pulmonary lymphatics

As the result of anatomical as well as histological investigations on the lymphatics of the human lung, the authors have arrived at the following conclusions: 1. According to the distribution and the direction of lymph flow, pulmonary lymphatics are classified into two systems and four groups. 2. The lymphatics cannot be found in the interalveolar septum. 3. The extravascular fluid pathway system plays an important role for cleaning particles in the most peripheral part of the respiratory tract where no lymphatics are found. 4. Efferent lymph flow reaches the venous angles via two routes on both sides respectively.     

Ultrasonography study of the mammary-coronary bypass

The authors present the case of a 49-year-old female patient who was admitted with the diagnosis of ischaemic heart disease and the syndrome of angina pectoris grade IV for selective coronarography. For assessment of the affection of one artery, significant stenosis of the insertion of the ramus interventricularis anterior the authors indicated a bypass of the left mammary artery to the ramus interventricularis anterior. During the postoperative course the patient did not have any anginous symptoms or any other clinical signs suggesting ischaemia or necrosis of the heart muscle. During the ultrasonographic check-up examination of the mammarocoronary bypass the suspicion of occlusion of the graft was expressed and this was confirmed on angiography. An angiographically successful percutaneous transluminal angioplasty of occlusion of the bypass was made. During the subsequent ultrasonographic examination the authors suspected again graft occlusion and angiography confirmed a 90% stenosis. Therefore the patient was re-operated. It appears that ultrasonographic examination of the mammacoronary bypass may prove useful in the diagnosis of occlusion or critical stenosis of a graft.     

埃立克体病的研究进展

人埃立克体病 (Humanehrlichiosis)也称无斑疹落矶山斑点热 (SpotlessRockyMountainspottedfever) ,是新近认识的一种危害较大的人兽共患的自然疫源性疾病。自 193 5年从阿尔及利亚的病犬体内发现第 1株埃立克体以来 ,随着病原种类的增加 ,人的感染与新病型的出现 ,该病的公共卫生学意义日渐突出 ,在美国掀起了研究热潮 ,同时亦引起其他国家的高度重视。我国蜱种繁多 ,分布甚广 ,与美国携带埃立克体的蜱相近似的蜱种在我国许多地方都存在 ,也发现了埃立克体病例 ,并从南方和北方的人、犬、蜱体内检测出埃立克体及埃立克体抗体 ,提示我国可…
