On day 1, sperm from diazinon-treated mice showed increased DNA breakages and reduced chromatin packaging, whilst DNA damage increased only in the diazinon 2/3 LD50
0 (2007) was used to calculate LD50
values of each sample for brine shrimp toxicity assay and anti-leishmanial activity.
Acute toxicity test: In the repeated acute toxicity tests, no mouse was found died, which indicated that the LD50
of ZQE was greater than 5,000 mg/kg.
For 2,4,5-trichlorophenol LD50
is much higher and is of 820 mg/kg of body weight, .
Experimental design: Based on the reported oral LD50
of Lead acetate for Wistar rats by Sujatha et al.
However, soranjidiol and soranjidiol 1-methyl ether were more photodynamically active for to reach LD50
, 37 [micro]M and 29.
64 ppm respectively and LD50
was determined statistically and found to be 0.
Studies on wild-type mice found that intraperitoneal injection at one-tenth of LD50
could induce the oxidative stress and couldn't kill the animal (Fu et al.
A computer program for estimating LD50
and its confidence limits using modified Behrens-Reed-Muench cumulant method.
EDs by road IP (179,9 mg ZnSO4, ~13 mg of Zn) can be hypothesized as a LD50
to rats in PN 68.
, a classification of acute ingestion toxicity, determined Suntheanine to be greater than 5,000 mg/kg, causing no "significant or unreasonable risk of illness or injury.
Labour PLEDGED "to ban the LD50
test", an unnecessary and brutal procedure in which animals are stuffed with a lethal dose of chemicals until half of them die, often horribly.
