Effects of disulfoton
Increase in performance in rats given disulfoton
at 10, 25, and 50 ppm in diet and water ad
libitum and inhibition of brain acetylcholinest-
erase by more than 75% of normal in the
most severely exposed group

Cholinesterase methods
Comparison of three cholinesterase methods

Importance of cholinesterase tests in applicators
prior to the aerial application season
Human blood
cholinesterase
Decrease of only 10% of the original cholinesterase
activity upon storage of red cell hemolysates
for less than 12 h at room temperature, up to
3 days at 4°C, and up to 6 weeks at −20°C
Crane et al.
(
1970b
)
Note: Whole-blood hemolysates and plasma
may be stored for 6 days at room temperature
and 6 weeks, if refrigerated or frozen.
Effects of endrin on brain
Brain bioelectric phenomena caused by
endrin at doses well below those causing
seizures or other gross behavioral changes
Revzin (
1970
)
Seizures in squirrel monkeys by chronic
administration of this pesticide
Reoccurrence of seizures some months after the
termination of endrin administration, under
stressful conditions, suggesting that this
phenomenon may have been caused by a
stress-induced release of endrin from
adipose tissue storage sites
Discussion on some implications of these
indings for aerial applicators
Disulfoton
Adverse effects on the reproduction system
in rats by disulfoton
Ryan et al.
(
1970
)
Note: The number of pregnancies was decreased
in the animals receiving this pesticide. Such
decrease could have been attributed to such
factors as alteration in the estrus cycles, the
receptivity of the female animals, and
decrease in sperm concentration or viability.
