[Principles of drug therapy in urogenital tuberculosis]

Every case of tuberculosis must be treated with drugs, especially before and after operative interventions. The therapeutic regimen consists of four different drugs, always including Isoniazid and Rifampicin. The length of treatment should be 7-12 months depending on the type of medication used. Most important for a successful treatment is the isolation of the mycobacterium before starting therapy according to the sensitivity testing. The effectiveness of therapy has to be controlled monthly by bacteriologic examinations. During the whole period regular examinations of the patient are necessary for the early detection of side effects.

[A pilot and a controlled study of the influence of ethambutol on serum urate concentration and uric acid clearance (author's transl)]

Ethambutol is said to be capable of elevating serum urate concentration. This statement was reconsidered in three investigations using strictly supervised administration of ethambutol in a single daily dose of 25 mg. per kg. of body weight: (1) In short term administration 10 healthy subjects received ethambutol for eight days. (2) In a pilot study 13 patients suffering from pulmonary tuberculosis were treated with a triple combination including thambutol for six months. (3) In a controlled trial 23 patients were randomly allocated to one of the following regiments: In the first group patients received ethambutol plus isoniazid plus rifampicin for six months. In the second group patients received streptomycin plus isoniazid plus PAS for three months and thereafter streptomycin plus isoniazid plus ethambutol for another three months. Serum urate concentrations and clearances of uric acid and of creatinine were determined periodically in all subjects. A slight increase in serum urate concentration occurring in long term therapy showed no relation to ethambutol administration, but was obviously dependant on parameters related to the course of the disease in form of increase in body weight and physical activity, or related to the well known syntropy of chronic alcoholism and tuberculosis.

Strahlenchemische Versuche zur Erzeugung von Blei- und Zinnradikalen

Triphenyltinchloride and -acetate, the corresponding lead compounds, and Tribenzyltinchloride are effective electron scavengers in γ-irradiated glasses from 2-Methyltetrahydrofuran at 77°K. The reaction with the electrons leads to the formation of tin- and leadradicals via dissociative electron capture. Only in the case of the benzyl compound the molecular anion is formed. Wavelength of absorption, extinction coefficients and relative rate constants are reported. The formation of lead radicals is confirmed by observation of their ESR absorption.
