摘要:

From the results of this study the conclusion can be drawn that radioimmunoassay (RIA) of diethylstilbestrol (DES) in crude urinary extracts may lead to highly unreliable results. Simple paper‐chromatographic purification, prior to radioimmunoassay, eliminates interfering substances responsible for ‘false DES’ values. Such a purification step is mandatory, certainly when the radioimmunoassay is used for statutory control purposes.

摘要:

The results of a mastitis control field experiment in Utrecht over three and a half years, including sevens herds with a total of 225 lactating cows are presented. Every case of clinical mastitis was examined bacteriologically. Quarter samples were taken routinely at an average interval of five weeks.

摘要:

A brief account is given of the research activities of the Institute of Veterinary Pharmacology, Pharmacy, and Toxicology (Faculty of Veterinary Medicine, Utrecht), during the professorship of H. van Genderen (1961–1980).

摘要:

A review of the side effects of antibiotics in human patients is presented. At least three classes of untoward reactions may be distinguished: development of drug hypersensitivity, toxicological hazards, and microbial effects such as emergence of drug resistance.

摘要:

Administration of feed additives is based on the necessity of satisfying a need in human nutrition. Oral feed additive intake results in an equilibration level which is followed by a steady state after absorption. The equilibrium point of the blood (tissue) level can be calculated mathematically. 70 Per cent of the plateau of the steady state is reached within four times the half‐life.

摘要:

After a short introduction of various chemicals of environmental concern that have been shown to alter cell‐mediated or humoral immune responses, a screening procedure is given to detect possible immunotoxic properties of chemicals. The different parameters in this screening programme include growth, weight and histology of lymphoid and endocrine organs, haematology, as well as serum immunoglobulin concentrations.

摘要:

Large scale pollution of the environment by pesticides and other chemicals only started in the fifties and early sixties. Chlorinated hydrocarbon pesticides and methyl mercury compounds appeared to have a marked impact on the populations of many animal species, especially birds. It is recognized that prof. dr. H. van Genderen, who retired this month, made a most valuable contribution to the timely detection of these problems in the Netherlands. Environmental toxicologists engaged in studies to predict environmental hazards by chemicals require toxicological skill as well as insight into the structure and functioning of ecosystems.
