ABSTRACT
MR tomography examination of 51 patients with maxillofacial or cervical cancer provided adequate diagnostic information especially in the absence of bone involvement. The method proved efficient in differentiating tumors with inflammation, in tumor localization, evaluation of its size and spread, outline, structure, invasion. It is safe, noninvasive. For differential purposes the technique is most beneficial in impulse double echo mode with proton density and T2.

In order to choose the most informative indicators of echohepatograms characterizing affections of the liver the results of an ultrasonic investigation of the liver were analized by using bSM-6 type computer. It was found that such indicators as the number of peaks, their summary amplitude may be made use of in making differential diagnosis of diverse hepatic lesions in children.

By the aid of histochemical methods the authors sutdied the activity and distribution of acetylcholinesterase, monoamineoxidase, glutamatedehydrogynase and gammaaminobutyric acid -- transferase in the dorsal hypocampus of rats. It was shown that the activity of all the studied enzymes are significantly changed following 0.5 and 1.5 hours and are restituted following 48 hours after the formation of a pathological focus. It is concluded that a drop in the activity of glutamatedehydrogenase and gammaaminobutyric acid may be directed toward an accumulation of gammaaminobutyric acid in the epileptogenic focus and an inhibition of its activity. A drop in the histochemical reaction to acetylcholinesterase may indicate a decrease in the functions of the cholinergic systems with an active epileptogenic focus in the hypocampus.
