Chicken embryonic cells (CEC) cultured in vitro were able to
withstand the toxicity of DDT at concentrations below 10μg/ml culture
medium. When the DDT concentration exceeded the toxic level, CEC
appeared vacuolated and lost the spindle-like fibroblastic appearance,
Gas chromatographic analysis had shown that the uptake of DDT (3μg/
ml'culture...
Attempts were made to study the effect of parathion and DDT
on the postnatal development of mice. Parathion, DDT or corn oil
(control) was administered to gravid mice during the first, second,
and third trimesters of pregnancy. Thus, nine groups of offspring
were obtained. Four different techniques, Audiogenic Seizure,
Conditioned...
A single oral dose of DDT, ranging from 40 to 200 mg/kg, had
a drastic effect on the in vivo acetate metabolism in rats. The normal
elimination pattern of the expired ¹⁴CO₂ from ¹⁴C-labelled
acetate was distorted, and the rate of output of the ¹⁴CO₂ was decreased.
The ratio of...
A study of mortality, food consumption, food utilization, and
polyhedral production following single and simultaneous challenges
of the variegated cutworm, Peridroma saucia (Hubner), with DDT
and a nuclear polyhedrosis virus was made. Fourth instar larvae
were challenged topically with three levels of DDT and per os with
three levels of...
