[Relationship between diet and some risk factors].

The authors evaluated data from the dietary histories of 203 individuals from Sofia and Varna who had been asked identical questions. The results of this investigation show that 42% of these these individuals have no marked liking for a certain diet (group 1), 28% prefer a high protein diet (group 2), 23% are partial to a high carbohydrate diet (group 3), and 6% give preference to a high fat diet (group 4). It was found that the individuals in group 1 showed the smallest deviations from the normal values for serum lipids.

[Effects of reduced diet and physical stress on liver lysosomes. Morphological and biochemical studies].

Groups of 15 rats each (I--non-reduced diet; II--non-reduced diet and physical stress; III--diet reduced by 40%; IV--reduced diet and physical stress) were examined after 20 and 140 days, respectively. The electron microscopic examination revealed that the most important changes had occurred in group III; there exists an excess of autophagolysosomes. The biochemical examinations show that the reduced diet (group III) also produces a considerable increase in activity of most of the lysosome enzymes in the liver.

[Comparative investigations of psychoses in parents, children and siblings (author's transl)].

Psychoses in 441 hospital patients from 210 families have been investigated comparatively. In 106 families 109 parents and 117 children suffer as do 215 siblings in 104 families.
