[Development in human ontogeny of the ability to reproduce a given rhythm]. / O formirovanii v ontogeneze cheloveka sposobnosti k vosproizvedeniiu zadannogo ritma.

Studies have been made on the capacity of persons from various age groups to reproduce the frequency of the given sonic sequence vocally or by hand. It was shown that each age group has its own optimal frequency band. The younger a person, the more narrow the zone of optimal reproduction of rhythm and the upper frequency of the reproduced rhythm. The highest precision of reproduction of the rhythm both vocally and by hand was observed in adult persons. In all age groups investigated, the highest precision of rhythmic reproduction is observed within the frequencies of amplitudal modulation of speech (3-6 Hz).

[Age-related characteristics of human perception of emotions in speech and in singing]. / Vozrastnye osobennosti vospriiatiia chelovekom émotsii v rechi i penii.

Monoaural presentation (in sequence to the left and right ears) of speech and vocal-musical phrases with different emotional content (joy, grief, anger, fear, indifference) has been made to children ageing between 7 and 16 years. These passages were performed by professional actors or singers. Absolute differences in the probability of correct identification of different emotions were obtained. They are maximal for fear and anger, being minimal for joy. Left ear preference to perception of emotions both in speech and in singing is already formed in 7-8 years old children.

[Interhemispheric brain asymmetry in speech perception by persons of different age groups and the "effect of directional attention"]. / Mezhpolusharnaia asimmetriia golovnogo mozga pri vospriiatii rechi u liudei raznykh vozrastnykh grupp i "éffekt napravlennogo vnimaniia"

Using dichotic tests, studies have been made on the degree of functional asymmetry of the brain with respect to perception of verbal information in 3-50 years old subjects. Significant age variations were found in the volume of the percepted speech information. Interhemispheral differences in speech perception, which reveal themselves in higher perception of the right ear as compared to the left one, are more evident in children under 10 years. Significant influence of the "effect of voluntary and involuntary attention" of the subjects was noted on the degree of asymmetry of dichotic speech perception, this influence alleviating the intrinsic functional asymmetry of the brain.

[Jejunostomy by Midle in patients with insufficiency of anastomotic sutures of upper parts of gastrointestinal tract]. / Midle ieiunistomiia v lechenii nesostoiatel'nosti shvov anastomoza verkhnikh otdelov zheludochno-kishechnogo trakta.

Insufficiency of anastomosis is one of the main causes of peritonitis. Progressed cachexia due to great losses through intestinal fistulas in combination with peritonitis was the indication to jejunostoma creation. Jejunostomy by Middle in the treatment of postoperative peritonitis due to sutures insufficiency of upper anastomosis of gastrointestinal tract permits to optimize treatment: to realize adequate enteral nutrition, intestinal decompression, to return fistula's losses. Polyorganic insufficiency, number of repeated surgeries and volume of loss through fistulas influence results of the treatment. Respiratory distress-syndrome and errosive bleeding have the most prognostic significance among the syndromes of polyorganic insufficiency.

[The trypanocidal action of fluorouracil on Crithidia oncopelti in the presence of lipid metabolic modifiers]. / Tripanotsidnoe deistvie ftoruratsila na Crithidia oncopelti v prisutstvii modifikatorov lipidnogo metabolizma.

Effect of fluorouracil in combination with ascorbate and L-valin, modifiers of lipid metabolism was studied in cultured protozoa Crithidia oncopelti. The inhibitory effect of preparation in a concentration of 100 mcg/ml gradually decreased in the course of cultivation. Its readdition to a 96-hour culture did not increase its effect on protozoa cells. Combined addition of fluorouracil and modifiers (100 mcg/ml each) resulted in insignificant decrease of the cell accumulation in the culture as compared with the effect of fluorouracil alone. When fluorouracil and modifiers were readded to the 96-hour culture, the trypanostatic effect of preparation was 2.5 times enhanced. This enhancement was confirmed by destructive alterations in cell morphology and by the culture lysis by 192 h of protozoa cultivation.
