[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]. / Biologicheskaia éffektivnost' belkov spetsializirovannogo produkta "Ovolakt" v pitanii bol'nykh posle rekonstruktivnykh operatsii na cheliustnykh kostakh pri vrozhdennykh deformatsiiakh.

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. Therefore, Ovolact can make more effective postoperative rehabilitation in jaw reconstruction.

[The efficacy of enriching wheat bread with lysine and its effect on gastric secretory activity]. / Effektivnost' obogashcheniia pshenichnogo khleba lizinom i ego vliianie na sekretornuiu deiatel'nost' zheludka.

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 0.2 to 0.7%. Further concentration increase induced amino acid imbalance. Certain characteristics of the effect of lysine-enriched bread on the digestive organs were revealed in experiments on dogs. Intensified secretion of gastric juice, pepsin and hydrochloric acid was recorded under the effect of lysine-enriched bread. The data obtained have evidenced the possibility and effectiveness of bread enrichment with lysine.

[Comparative biological value of the proteins comprising the products for the tube and regular feeding of patients with mandibular fractures]. / Sravnitel'naia biologicheskaia tsennost' belkov v sostave produktov zondovogo i obychnogo pitannia bol'nykh s perelomami nizhnei cheliusti.

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. In this respect the products for tube and dietotherapy have proved to be effective and completely provide the need of such patients in essential amino acids that has been evidenced by the results of the investigations conducted.

[Clinical study of the assimilation, tolerance and metabolic effectiveness of protein products combined with a soybean isolate]. / Klinicheskoe izuchenie usvoiaemosti, perenosimosti i metabolicheskoi effektivnosti kombinirovannykh belkovykh produktov s izoliatom soi.

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 (95.5-95.9%) and pronounced hupocholesterolemic effect of the soybean isolate when it was used as a substitute for 2/3 or 1/2 protein volume in the ration.

[Intravenous alimentation of rats in renal failure]. / Vnutrivennoe pitanie krys s pochechnoi nedostatochnost'iu.

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. Oral feeding with the diet containing casein (9.5% of energy value) was more effective as regards the reduction of uremia and maintenance of the general status of the body.

[Substantiation of an optimal protein quota in the diet of patients with chronic pancreatitis based on the study of nitrogen balance]. / Obosnovanie optimal'noi kvoty belka v ratsione bol'nykh khronicheskim pancreatitom po dannym issledovanii azotistogo balansa.

Based on nitrogenous balance studies performed under the clinical conditions in patients with chronic pancreatitis given the diet with different protein content (80, 120 and 150 g/day) it is recommended that the optimal protein quota should be equal to 114-120 g/day in the diets intended for patients' population in question.

[Comparative biological value of protein hydrolysates and their fortified forms]. / Sravnitel'naia biologicheskaia tsennost' belkovykh gidrolizatov i ikh obogashchennykh form.

Experiments on Wistar male rats were made to study the biological value (with the use of the "growth" method) of basic and protein- and crystalline amino acids-enriched protein hydrolysates. Autolysine and protein hydrolysates obtained from formed elements of the blood of slaughtered animals (the degree of degradation 30 and 70%) and a mixture of crystalline amino acids composed according to the FAO/WHO scale were studied. Casein was used as control. The differences in the biological value of basic and protein hydrolysates-enriched preparations point to the necessity of correcting basic hydrolysates.
