Disposition of [3H]flobufen and its active metabolite in rats

The present authors investigated the excretion, distribution and pharmacokinetics of the novel potential antirheumatic agent flobufen and its active metabolite after p.o. and i.v. doses of 2, 10 and 50 mg/kg administered to rats. The drug is resorbed well from the digestive tract and mostly it is metabolized to the principal metabolite M, which is only slowly excreted from the organism mainly by renal clearance. Within the whole dose range the kinetics of the drug is linear. Binding of flobufen and M to proteins is high (95-99%). The highest concentrations of radioactive metabolites (mostly M) were found in the plasma, liver, lungs, kidneys, connective tissue and inflammatory foci. The penetration of metabolites through the placenta and excretion in human milk are relatively important.     

Bilateral dacryops

The clinical, radiologic, and histopathologic findings of a case of bilateral dacryops is reported in a 49-year-old man. The patient presented with cystic masses located in superior lateral orbits and underwent bilateral excisions of these without any postoperative complications.     

Modulation of mild bleeding disorder during remissions and exacerbations of Graves' disease

A patient with Graves' disease had a symptomatic thrombocytopathy during periods of remission. When euthyroid, she noticed bruising, petechiae, and epistaxis. Hemostatic abnormalities included prolongation of the bleeding time by aspirin, reduced platelet retention (a second-phase defect), and abnormal thrombin-induced aggregation and serotonin release. When hyperthyroid, bleeding symptoms resolved, and platelet function returned to normal. These observations suggest that mild bleeding disorders may be influenced either directly or indirectly by thyroid hormone levels.     

Computed tomography of the brain in the Smith-Lemli-Opitz syndrome

Computed tomographic (CT) scans of the brain in a child with Smith-Lemli-Opitz syndrome revealed enlargement of the ventricular system, hypoplasia of the cerebellum, and abnormal thickening of the gray matter, consistent with pachygyria. These findings have been previously noted in autopsies performed on patients with this disorder. We conclude that CT scanning is a valuable tool in the evaluation of children suspected of having the Smith-Lemli-Opitz syndrome.     

港九海底铁路建设中的减压病——工作条件与发病关系探讨

本文介绍香港九龙海底铁路建设中高气压作业与减压病发病情况。该工程有11条坑道,共计259 448个高压工作日,减压288 140人次,发生减压病1 534例。根据不同的工作压力,以暴露次数、高压工作日数及暴露4小时以上次数3种方法分别计算减压病发病率。结果表明:各种方法计算出的发病率都有随工作压力增高而上升的趋势,说明现用的减压表对不同的工作压力达不到同样的预防效果。本文还对3大主要工种和14个小工种的减压病作了分析。     

Cytophotometric investigations on atypical epithelial cells of the human seminal vesicle

Normal seminal vesicles were studied histologically in 80, and by Feulgen’s cytophotometric method in 10 autopsied cases (males, 44–82 years of age). In every case large, hyperchromatic nuclei were found. By cytophotometry euploid polyploid atypia was also shown in every case, which is characteristic of benign hormonal dysplasia.
