[The biological effectiveness of the proteins in the specialized product "Ovolact" in the nutrition of patients following reconstructive surgery on jaw bones with congenital deformities].

Postoperative feeding with a special-purpose foodstuff Ovolact proved superior to tube feeding in patients on after treatment following surgical correction of congenital jaw defects. This was evident from assessment of anthropometric and protein metabolism parameters. Nitrogen metabolism underwent positive changes reflecting the product value for maintenance of protein status of the above patients.

[The efficacy of enriching wheat bread with lysine and its effect on gastric secretory activity].

A high biological effectiveness of bread enriched with microbiologically synthesized lysine has been proved in experiments on rats which were fed with this bread. Optimum lysine concentration for bread enrichment has been determined. The biological value of bread proteins with respect to all growth parameters increased proportionally, within the range of lysine concentration from 0.

[Comparative biological value of the proteins comprising the products for the tube and regular feeding of patients with mandibular fractures].

A comparative clinical evaluation was made of the biological effectiveness of protein components in the composition of three types of diet for patients with fractures of the mandible who had received "Ensure" (USA), a product for complete tube feeding; an experimental sample developed at the Institute of Nutrition, Academy of Medical Sciences of the USSR; and a routine clinical diet. The biological effectiveness of the proteins was estimated by some anthropometric and biochemical parameters as well as on the basis of nitrogenous metabolism in the patients. It has been established that the protein content in the routine clinical diets does not meet the high requirements in amino acids of patients with fracture of the mandible.

[Clinical study of the assimilation, tolerance and metabolic effectiveness of protein products combined with a soybean isolate].

Combined product containing soybean isolate 500E (produced by "Ralston Purine Company", USA) were clinically used in 16 patients with hyperlipidemia, type II. The results obtained evidenced a high assimilability (95.5-95.

[Intravenous alimentation of rats in renal failure].

Experiments on nephrectomized rats were made to compare the effect of oral and intravenous feeding on the degree of uremia and general status of the body. Intravenous feeding which included only essential amino acids as nitrogenous component or an insufficiently balanced mixture of essential amino acids and several replaceable amino acids (9.5% of energy value) did not produce any correcting action on the uremic status.
