A full-scale, laboratory building section at Silsoe Research Institute was adapted to simulate cross-ventilating air#ow patterns representative of those that develop in naturally ventilated, intensive livestock buildings. In the fully controlled, steady-state environment of the building section, the

β¦ Synopsis
Experimental cardiac infarction produced in dogs by coronary artery ligation has been used to investigate the value of macroscopic histochemical enzyme loss in the diagnosis of myocardial infarction at post-mortem. Creative phosphokinase and non-specific dehydrogenase methods gave the best results but became positive only 5-6 hr after infarction. It is concluded that the method is of limited value in autopsy practice.

An experimental technique is described, which allows to discriminate between series and parallel enzyme deactivation patterns. It consists in monitoring the enzyme activity as a function of time and in step-increasing the temperature, at a given stage of the deactivation process. Single-step deactiv
