パラチオン中毒に於ける呼吸及び循環機能並びに之に及ぼす治療剤の影響

Respiratory movement and blood pressure were recorded on the dog with parathion-poisoning. 1. After a few minutes of increasing of rate and amplitude, the respiratory movement go down weaker and irregular. Thus the movement ceases by a single intravenous injection of 10 mg/kg parathion. Blood pressure shows transitory rise, then it falls gradually and is attended by a marked slowing of the heart beats after respiratory failure. 2. The changes caused by parathion injection are protected by 5 mg/kg atropine i. v. 3. The atropine- like effects are displayed, too, by 1 mg/kg Tropin, 4 mg/kg Finalin and 3 mg/kg Pro-banthin i. v. 4. Intravenous injection of 100 mg/kg Theraptique, 20 mg/kg Guronsan and 300 mg/kg Sod. thiosulf. are of no use, besides the former display a brief period of strong respiratory stimulation.
