ABSTRACT A testosterone test using two different dosages was carried out simultaneously in 7 women suffering from metastasizing carcinoma of the mamma and in 3 normal women. In each case the urinary steroids were estimated before the beginning of the test and after administration of 50 mg and 100 mg of testosterone respectively; the interval between the single estimations being one week. The use of fractionated hydrolysis enabled a mild fission of the conjugates and the classification of the products into free steroids, glucuronosides, sulfates and unknown conjugates. The 17-ketosteroids and the testosterone were estimated by means of Girard's separation and adsorption chromatography. During the loading test with testosterone different behaviours became evident, which had not been realized before. The behaviour of the 17-ketosteroids rendered possible the differentiation of normal women from patients with cancer of the breast yet without hepatic insufficiency, and furthermore of these latter ones from those with a liver damage in addition to the cancer of the breast. The glucuronosides of the 17-ketosteroids are only depressed, when there exists a pronounced damage of the liver; the loading test making possible an extension of the range of recognizable damages. Furthermore, the behaviour of dehydroepiandrosterone (II/III), of androsterone (IV), and of aetiocholanolone (V) lends itself to this differentiation. In advanced cancer of the breast the values of II/III are invariably low, whilst IV and V often increase temporarily. The relation of IV to V may be altered in a different way. The excretion of not transformed testosterone is less in patients than in normal women and especially low in patients with liver damage.

In two parts of the article, more than 70 errors and violations of the Biotechnics of artificial breeding of Pacific salmon in salmon hatcheries are collected and summarized, which lead to an immediate or delayed deterioration of the quality of reared fry and a decrease in their survival rate. Deviations from the biological basis of fish farming are shown and possible consequences of such errors or violations are predicted. In the first part of the article (#7,2020) there were General errors (throughout the entire fish-breeding process), as well as violations of Biotechnics during the work with producers, collecting eggs and preparing them for incubation, in the second part-violations of Biotechnics during the incubation of eggs, holding pre-larvae, rearing and release of young. Their correction, prevention or minimization of consequences will significantly improve the quality of sexual products and offspring from producers, increase the linear and weight gain of juveniles during rearing, improve the coefficient of feed payment, reduce the time of rearing, improve the epizootic situation by developing immunity in fry and mobilizing other protective reactions of their body, significantly reduce waste at all stages of the production process, increasing survival by 10–15%. In conclusion, it is noted that the first and most important condition for an efficient salmon hatchery is the creation of optimal environmental conditions at each stage of the production process. The second condition is strict compliance with the Biotechnics of artificial salmon breeding and the complex of veterinary and sanitary, fish-breeding and meliorative and therapeutic and preventive measures. The third is the availability of competent specialists who regularly improve their skills in accredited Universities to implement, control and manage the first two conditions.
