Hepato-Quick: a new diagnostic test for liver diseases (author's transl)]

The AA. have adopted usual biohumoral examinations and the Hepato-Quick test for a group of patients affected by various liver diseases. Hepato-Quick contains thromboplastine from monkey brain and plasma absorbed on barium sulphate. It is particularly sensitive for II, VII and X factor and it does not react on deficit of V factor and fibrinogen both already present with optimal concentration in the Hepato-Quick test. II, VII and X factor are synthetized by the liver and reveal in an outstanding way every hepatocytic lesion: therefore is the Hepato-Quick test a fine and responsive test for the liver function and in order to control the liver diseases, especially if chronic. We have seen the new test is strong altered by hepatic cirrhosis, but there are no significant alterations in different liver diseases.     

A mechanized enzymic method for the determination of uric acid (author's transl)]

A continuous flow method is described for the determination of uric acid in serum using uricase and peroxidase, with omicron-dianisidine as the chromogen. The method can be used with single channel systems and with the multichannel system SMA 12/60 (Technicon). The new method was compared with six other manual and mechanized methods for the dosage of uric acid, and the results were analyzed statistically. The results from all the enzymic methods showed a good correlation, whereas the "chemical oxidation" methods showed systematic deviations.     

A rapid method for the isolation of Salmonellae from faeces (author's transl)]

A rapid and simple method for detecting Salmonellae in faeces was developed. It was based on the motility of Salmonellae through a semi-solid medium in a U-tube. The migration of other intestinal bacteria was retarded by means of a magnesium salt concentration. 474 stool specimens were examined for Salmonellae in parallel with the usual isolation method. A total of 39 Salmonella strains were isolated, 37 (94.9%) by means of the selective migration procedure, 26 (66.7%) when the routine method was applied. Two strains of patients in chemo-therapy were missed by the rapid method, which was moreover inefficient in detecting S. typhi, due to its slow motility. However, the rapid method is recommended in addition to conventional mediums in screening of carriers for its higher frequency of positive isolations compared with multistep procedure (+27.3%).     

City guides for the disabled - an interim balance (author's transl)]

The following article wants to bring city guides for the disabled into focus, which appeared in rapid succession in the Federal Republic of Germany since 1971. After reflecting about the purpose and effect of city guides upon the consumer, city planners, and the wider public the author surveys hitherto published guides. Based on his own essential contribution to the making of the guide to the city of Ludwigshafen the author retraces the various stages of conception.     

Ezymatic method for the automated determination of total serum cholesterol (author's transl)]

A simple kinetic method for the automated determination of total serum cholesterol was developed using cholesterol esterase, cholesterol oxidase, catalase and the color reaction according to Hantzsch. The procedure has been adapted to the Braun SysteMatik, Greiner GSA II, Eppendorf 5032, Lars Ljungberg Autolab, Perkin-Elmer C4 and Perkin-Elmer C4B analyzers. The variants of the method yielded satisfactory results with regard of precision, accuracy and sensitivity to interferences.     

Tbual Sterilization (author's transl)]

During the years 1975, 1976 and 1977 2481 tubal sterilizations were performed, either simultaneously with gynaecological operations or Caesarian sections, as an independent operation post partum or by laparoscopy. Unipolar, bipolar or thermocoagulation was used for tubal occlusion. Primary surgical complications occurred in 0.36% of the patients. Until March 31st, 1978 6 women (0.24%) became pregnant after tubal coagulation; so far 2 women have asked for reversal of the operation. From the surgical point of view, on the basis of the basis of these figures, it is a low-risk, dependable (Pearl index 0.13), irreversible method of contraception.     

T-cell lymphoma (author's transl)]

The percentage of T- and B-lymphocytes was determined by means of surface markers in 190 patients suffering from various lymphoproliferative disease. Characteristic T-cell lymphomas were diagnosed in 8 patients: 2 of these patients suffered from acute leukaemia, 2 from lymphoblastic lymphoma, 3 from mycosis fungoides and one from the Sézary syndrome. The clinical course of the disease in these patients, the clinical picture and the results obtained with various surface markers and with unspecific mitogens are described and discussed.
