Use of thiamine for correcting the immune response during physical loading

A study was made of the effect of thiamine on the development of the immune response under exercise. It was established that the 4-hour swimming inhibited the development of the immune response to sheep red blood cells in Wistar rats fed about 40 g thiamine per day with the diet. Additional administration of 100 g vitamin increased the intensity of the immune response after exercise. The serum from the swimming rats suppressed the development of the immune response in intact animals. Thiamine did not produce any effect on the exercise-induced synthesis and release of immunosuppressant factors but reduced the sensitivity of effector cells of the humoral immune response to the action of those factors.     

Hygienic characteristics of food hydrolysates made from small ocean fish and krill

A study was made of the biological value of acid and enzymatic hydrolysates from capelin, luminous anchovy and krill. Hydrolysates were obtained with the use of protosubtilin G-10-X or hydrochloric acid. The products were found to contain 39 to 64% of "crude" protein, with about 40% of total nitrogen belonging to non-protein one, 0.47-2.07% of lipids, 29.7-54.3% of mineral substances including 26.6-52.4% of sodium chloride. All the hydrolysates were limited in tryptophan, the deficiency being more demonstrable in acid hydrolysates. Enzymatic hydrolysate from luminous anchovy was rich in sulfur-containing amino acids (score 112%), whereas the remaining products were marked by their deficiency (score 53-90%). The products were rich in lysine, leucine, isoleucine, and aromatic amino acids. The anabolic efficacy was discovered to be the highest for enzymatic hydrolysate from luminous anchovy, exceeding the analogous characteristics for casein. The biological value of hydrolysate from capelin and krill was lower than that of casein. This was supported by the amino acid analysis data. The assimilability of all hydrolysates was established as fairly high. Hydrolysates are employed for manufacturing broth bricks and pastes.
