Test animals

Species:
rat
Strain:
Sprague-Dawley
Sex:
female
Details on test animals or test system and environmental conditions:
The test animals were 175 to 225 gm, adult, virgin female rats. Male rats  of thesame strain and age were 
used as the "stud pool".

Administration / exposure

Route of administration:
intraperitoneal
Vehicle:
not specified
Details on study design:
Acute toxicity  was determined by administration of graded doses of these specific  samples by intraperitoneal 
injection in rats and observation of the rats  for 7 days for mortality.
Statistics:
Acute LD50-values and 95 % confidence limits were calculated by Cornfield  and Mantel's modification of Karber's 
method or by the method of Weil.
