Experimental studies on the chronic toxic effects of vinyl chloride in rats.
TLDR
Male rats were exposed to vinyl chloride at the concentrations of 50, 500, and 20 000 ppm for 10 months and some toxic effects including morphological liver injuries arose at the smallest exposure level, i. Expand
Light and electron microscopic observations on rat thyroid after administration of some dithiocarbamates.
TLDR
It is suggested that the changes described are the result of increased thyrotropin stimulation. Expand
Study on the long-term effects of some pesticides.
TLDR
The hygienic significance of the studies on pesticides from the aspect of their "long-term" effects upon the individual and the generations are emphasized and the results are discussed. Expand
Changes in the gonads, reproduction and generations of white rats under the effect of some pesticides.
TLDR
Assessment of the gonadotropic effect of pesticides, together with changes in reproduction and in the offspring, and some evaluation of the functional state of given organs (liver, brain, testes) might be performed. Expand
Effect of subacute oral administration of zinc ethylenebis(dithiocarbamate) on the thyroid galnd and adenohypophysis of the rat.
Summary The thyroid gland and adenohypophysis were studied after twice weekly oral administration of zinc ethylenebis(dithiocarbamate) (zineb) by gavage to rats for 4·5 months in doses equivalent toExpand
Toxicological evaluation of agromet (Metalaxyl) preparation.
TLDR
A complex toxicological study was carried out in relation to the hygienic standardization of the fungicide preparation Ridomil, whose forthcoming production in this country will be under the name Metalaxyl, with results that permitted the Agromet preparation to be put in III class--moderately toxic according to limiting index LD50 oral. Expand
Attempt of biological dosage of some hypophyseal hormones in white rats after experimental oral administration of Zineb.
TLDR
It is suggested that the functional and morphological adenohypophyseal changes described here serve to compensate the disturbed hormonal balance after application of this compound. Expand
[The toxic hygiene problems of workers in the Dinamik automobile tire plant in Sofia].
TLDR
Toxic hygienic investigations were carried out involving a representative group of 131 workers at "Dynamic" automobile tire plant in Sofia, pointing to changes in hemopoiesis, deviations in hepatic functional state, while sulfate and glucuronide values confirmed the workers' high exposures. Expand
Dose effect relationship for some specific effects of dithiocarbamates.
TLDR
Data from a chronic experiment on albino rat thyroid gland and gonads and teratogenicity give grounds to recommend a higher security coefficient in hygiene standardization. Expand
