Four groups of 5 male 6 5 female albino rats of the Sherman-Wistar Strain weighing between 200 and 300 gm were employed in this study. The rats were deprived of food but not water for 2k hours prior to dosing. Each animal was weighed and dosed by direct administration of the experimental material into the stomach by means of a syringe and dosing needle. The sample was dosed as supplied. The following dosage levels were administered: 0.50 ml/kg. 2.50 ml/kg. 3-75 ml/kg. 5.00 ml/kg. Resu1ts: Conclus ion: Following administration the animals were allowed food and water ad libitum for the H day observation period during which time the rats were observed for signs of toxicity and mortalities. See Table 1. The subject material when studied in male and female albino rats has an acute oral LD50 between 0.5 ml/kg. and 2.5 ml/kg. 000182 Karl L.

At 0.50 ml/kg. the animals were slightly depressed for 4-6 hours after dosing. At the three higher dosage levels the animals were comatose within 30 minutes to 4 hours and died as noted. Gross pathologic examination revealed nothing remarkable. Initial Weight gm 215 230 225 250 210 235 220 2*0 Final We ight gm 245 255 - - - - -
