[Effect of the temperature regimen on the kinetic and thermodynamic functions of the enzyme urease in the helminths of warm-blooded and cold-blooded animals].

The determination of the constant of the urea fission rate and study of the temperature dependence (activation energy) of the urease activity on warm- and cold-blooded animals in Ascaris suum and Contracaecum aduncum were undertaken. It has been shown that the constant of the urea fission rate in C. aduncum is more than an order of magnitude higher than that in A.
