was calculated after Matsumura (1975).
2mg/kg body weight of n/s (0 hours) or LD50
Cobra venom (1, 1.
values of topical exposure showed that confidor is highly toxic at field rate in the laboratory.
The acute effects of malathion (single intraperitoneal injection), 1/12 the LD50
to mice were analyzed at l, 8, 16, 35 and 40 days after injection, in terms of spermatogenic cell proliferation and apoptosis and of Sertoli cell compromise as revealed by immunocytochemical detection of CK-18 (cytokeratin).
The treated seeds along with control were sown in soil for LD50
resulted in lower LD50
values with small droplets than with large droplets.
Subacute toxicity testing of rats for 6 months at one-sixteenth to one-fourth of the LD50
dose revealed pathological changes mainly in the lymphatic and reproductive systems (Wang et al.
NM-5 and NM-6 fractions were cytotoxic, with LD50
values of 175.
The calculated LD50
and LT50 values suggested that malathion was more toxic than trichlorofon and -cyhalothrin.
calculated with TSK software was 1397 mg/kg body weight for methanol extract of leaves observed in albino mice.
Three replications, for each test dose, were used for each age and fish species for the determination of 96 h LC50 or LD50
and lethal concentrations (as total metal concentration).
From this study, the LD50
for the methanol extract of Zingiber officinale was 214.
lavandulaefolia (Spanish sage) essential oil diluted 1:2 in sunflower oil (Safeway commercial product) once per day for 5 days (the LD50
of the oil being more than 500 times greater than the doses used).
Thus it is so special interest to examine the possible effects of LD50
of the crude venom in kidney of rats after 4 h of envenomation.
