Abstract: | The influence of various conditions at blood-letting on the concentration of SP in the plasma was investigated in male Wistar rats as background for following studies on effects of noxae. Narcotic substance (hexobarbital, ether), CO2-suffocation and the mechanical kinds of killing (cervical dislocation, occipital hit, decapitation) influence the SP concentration in different ways. It is assumed SP concentration in plasma after cervical dislocation to be the best corresponding value for physiological conditions. |
