Reevaluation of the acute toxicity of palytoxin in mice: Determination of lethal dose 50 (LD50) and No-observed-adverse-effect level (NOAEL)

open access: closedToxicon, 2020
Palytoxin is an emergent toxin in Europe and one of the most toxic substances know to date. The toxin disrupts the physiological functioning of the Na+/K+-ATPase converting the enzyme in a permeant cation channel. Human intoxications by PLTX after consumption of contaminated fishery products are a serious health issue and can be fatal.

Effect of Intraventricular Administration of Antisomatostatin γ-Globulin on the Lethal Dose-50 of Strychnine and Pentobarbital in Rats*

Endocrinology, 1978
Effects of intraventricular injection of sheep anti-somatostatin gamma-globulin (anti-SSG) on strychnine-induced seizures, strychnine LD50, and pentobarbital LD50 were examined in male rats under light ether anesthesia. Ten microliters of anti-SSG given 2 h earlier significantly decreased the duration of strychnine-induced seizures as compared with ...

The Number of Elementary Bodies Per 50% Lethal Dose of Meningo-Pneumonitis Virus as Determined by Electron Microscopic Counting,

open access: closedThe Journal of Immunology, 1954
Summary Counting of elementary bodies of meningo-pneumonitis virus in dialysed allantoic fluid by electron microscopy is described. Dialysis against distilled water for 18 to 24 hours at 5°C did not alter the lethal potency of the fluid for chick embryos inoculated via the yolk sac.

The relationship between faecal egg count reduction and the lethal dose 50% in the egg hatch assay and larval development assay

Veterinary Parasitology, 1998
The relationship between resistance detected in the faecal egg count reduction test (FECRT) and the lethal dose 50% (LD50) in the egg hatch assay (EHA) for benzimidazoles (BZs) and a larval development assay (LDA) for BZs, levamisole (LEV) and ivermectin (IVM) was examined on 13 sheep farms and 12 goat farms in Denmark. Out of 10 farms where resistance

[Ciradian variation in the lethal dose 50 of mercuric chloride in mice].

open access: closedComptes rendus des seances de l'Academie des sciences. Serie III, Sciences de la vie, 1982
If circadian variations in tolerance to drugs have been often demonstrated, such observations about heavy metals are still very scarce. The present study proposes to determine if circadian variations occur in the tolerance of Mice to single lethal dose of mercuric chloride. 360 female Mice, kept in cages on a 8.00 - 20.00 L/D cycle, receive I.P.
