THE INFLUENCE OF THE SIMULTANEOUS EFFECT OF X-RAY IRRADIATION AND SOME NARCOTICS AND STIMULANTS ON THE MORTALITY OF TADPOLES (in Russian)
Tadpoles of Rana esculenta were selected for experiments to ascertain changes in the action of irradiation produced by certain narcotics and by strychnine. The control tadpoles were irradiated with a dose of 27,500 r, as were also tadpoles in a watery solution of one of the following substances: ether (0.1%), ethanol (2 and 2.5%), chloral hydrate (0.3%), avertine (irradiation in water for 5 mins. in 0.1% solution), strychnine (1: 100,000, of the tadpoles irradiated in the watery solution of narcotic substances is in all cases statistically and significantly prolonged in comparison with that in the case of the tadpoles irradiated in water. Strychnine in a concentration of 1: 100,000, which produced signs of irritation, produced sensitivity to irradiation; in concentrations of 1: 50,000 and 1: 30,000, which produced inhibition, it had a protective effect, in as far as the tadpoles survived the toxic action of the strychnine. It would appear that irradiation intensifies the toxic action of avertine, ether, chloroform, and scopolamine. (auth)
