肾上腺髓质微血管构筑

本文以树脂铸型扫描电镜法,观察大鼠和小鼠肾上腺髓质的微血管构筑,并特别注意髓质血管和皮质血管的相互关系;此外切片观察测量了肾上腺髓质两种嗜铬细胞的分布。肾上腺皮质集合小静脉发出侧支,分布于髓质,构成了门静脉循环特点。小鼠的肾上腺髓质,主要由这种侧支供应;而大鼠的髓质,还有多支髓质动脉供应。从血管铸型上表现出的明显局部环形缩窄推测,肾上腺髓质血液循环有若干括约装置控制。大、小鼠两种嗜铬细胞在肾上腺髓质内的分布不同,大鼠的呈随机分布;小鼠的 NA 细胞多靠近皮质,而 A 细胞多远离皮质。     

Histopathological features of congenital fundus lesions in familial adenomatous polyposis

We report the light and electron microscopic findings for two lesions from two patients who died of complications of familial adenomatous polyposis. In the first case microscopy of a small (100 to 200 mu), uniformly dark lesion (the commonest type seen in this condition) showed enlarged retinal pigment epithelial cells with an increased number of pigment granules. This is consistent with the term "hypertrophy of the retinal pigment epithelium", currently used to describe these lesions. In the second case we sectioned a larger (1000 to 1500 mu), oval, grey lesion from the posterior pole. The pigment epithelium was normal, but between it and outer retina was an unusual choristoma consisting largely of myelinated axons and astrocytes.     

顺铂术中腹腔化疗对妇科恶性肿瘤患者术后的近期影响

目的 探讨顺铂术中腹腔化疗治疗妇科恶性肿瘤的可行性。方法 60例妇科恶性肿瘤患者术中腹腔置入100mg顺铂稀释液,观察其对患者术后胃肠功能、体温、切口愈合、腹水控制及术后并发症的影响。结果 术后24h内呕吐发生率增高,但使用止吐剂及水化效果好,尿量达标;胃肠道功能按期恢复;术后发热发生率低;服务部切口无一例丙级愈合;无并发症发生。14例伴发大量腹水患者11例得到控制。肝肾功能未发现损害。结论 术中腹腔化疗比较安全,切实可行。     

小脑和脑干梗塞致突发性耳聋

目的:了解小脑和脑干梗塞引起的突发性耳聋的临床特点.探讨其发病机制.方法:回顾性分析12例小脑和脑干梗塞所致突发性耳聋的临床资料.结果:该组患者主要临床表现为耳聋、眩晕、耳鸣、眼震、同侧颜面麻木感.头颅CT或MRI发现小脑或脑干有小于2 cm的梗塞灶.结论:发病机制主要为小脑前下动脉(AlCA)供血不足使小脑脑桥角或脑干缺血,损伤该区域的耳蜗神经和听神经传导通路,导致耳聋.小脑和脑干梗塞的诊断主要依据临床表现、CT或MRI检查.

中药肛滴在治疗消化道恶性肿瘤中的应用

探讨中药肛滴在治疗消化道恶性肿瘤中的应用。通过对６例典型病例的回顾分析,观察中药肛滴在缓解癌性粘连性肠梗阻、缓解消化道恶性肿瘤患者症状、提高晚期消化道恶性肿瘤患者生存质量的作用。应用中医理论“通则不痛”之说,对消化道恶性肿瘤患者进行中药肛滴治疗．认为有较好的临床效果。     

Influence of the concentration of metipranolol eye drops on the drug concentration in human aqueous humour

The concentration of the metabolite of the beta-blocker metipranolol was determined in the aqueous humour of 89 cataract patients. At 1, 2 or 5 h before surgery, they received one drop (30 l) of a 0.1 % or 0.3% solution of the drug. At 1, 2 or 5 h after the application of 0.1 % metipranolol eye drops, desacetylmetipranolol concentrations of 624.55, 235.29 and 88.02 ng/ ml, respectively, were measured. At the same intervals after the instillation of 0.3% metipranolol eye drops, the respective values of 1289.20, 1120.88 and 327.36 ng/ ml were found. The metabolite concentration in the eye drops and the values measured show no consistent correlation.Offprint requests to: H. Bleckmann     

End-to-side neurorrhaphies of the ulnar and median nerves at the wrist: report of two cases without sensory or motor improvement

The authors present two unsuccessful clinical cases of end-to-side neurorrhaphy. In the first patient the distal median nerve was coapted in an end-to-side manner to the intact ulnar nerve. In the other patient four cables of sural nerve graft were used to bridge the ulnar nerve and the intact median nerve by two end-to-side coaptations. Neurorrhaphies were performed via epineural sutures through epineural windows. Both of the cases failed to demonstrate any signs of regeneration either clinically or as evidenced by electromyography, Semmes-Weinstein monofilament test, or 256-Hz vibration tests at 18 and 21 months' follow-up respectively.     

术前术后介入治疗30例子宫颈浸润癌

目的：应用介入、手术、再介入的方法治疗子宫颈浸润癌30例，观察其消长变化，与以往的常规治疗方法相比较，评价该治疗方案在临床上的应用价值。方法：收集子宫颈浸润癌Ⅰb-Ⅲ期患者30例，术前常规行盆腔介入治疗。介入后14天，行子宫颈癌根治术，术后根据临床分期分别再介入3-6次。结果：30例患者经过介入、手术、再介入治疗后，分别追踪随访1-6年，未见复发。结论：子宫颈癌介入、手术、再介入治疗，效果肯定，并可延长患者的生存时间，值得临床借鉴。
