[Gypsy moth Lymantria dispar L. in the South Urals: Patterns in population dynamics and modelling].

The analysis is conducted on population dynamics of gypsy moth from different habitats of the South Urals. The pattern of cyclic changes in population density is examined, the assessment of temporal conjugation in time series of gypsy moth population dynamics from separate habitats of the South Urals is carried out, the relationships between population density and weather conditions are studied. Based on the results obtained, a statistical model of gypsy moth population dynamics in the South Urals is designed, and estimations are given of regulatory and modifying factors effects on the population dynamics.

[Diagnosis and combined treatment of esophageal chemical burns in children]. / Diagnostika i kompleksnoe lechenie khimicheskikh ozhogov pishchevoda u detei.

The experience of management of 426 children with chemical burns of the esophagus and the stomach has been analyzed. The necessity of earlier (up to 3 hours) lavage not only of the stomach, but also of the esophagus, is substantiated. It is considered advisable to carry out diagnostic fibrogastroesophagoscopy not later than 1 day after the trauma and to give up early prophylactic bouginage of the esophagus. The latfer rather stimulates sear formation than prevents it. The developed scheme of treatment was used in 256 patients with resultant decrease of postburn stenoses of the esophagus 3 times is the results of conventional methods of treatment.

[Motivational dependence of centrifugal "tuning" influences on taste receptors]. / O motivatsionnoi obuslovlennosti tsentrobezhnykh "nastroechnykh" vliianii na vkusovye retseptory.

Bioelectrical activity was registered in the central sector of the glossopharyngeal nerve. The impulsation was processed on a specialized computer "ATAK-350" in the real-time regimen. Interval histogramms were made, based on the result of survey of 500 inter-impulse intervals. It has been established that during a 4-day food deprivation bimodal distribution of inter-impulse intervals takes place. The first maximum occurs within 10-15 ms, the second--within 190-200 ms. After the irritation of the stomach by the rubber balloon, containing 1.5-2.0 ml of water, monomolar distribution of inter-impulse intervals (with the maximum in the range of 55-60 ms) takes place. It is believed that specific motivating excitement is manifested not only in central structures, but also involves peripheral receptor structure and tunes them to accept adequate stimuli.

[Effect of actinomycin D and ethionine on hormonal induction of ribonucleic acid synthesis in the nuclei and cytoplasm of the liver cells of adult male rats]. / Vliianie aktinomitsina D i étionina na gomonal'nuiu induktsiiu sinteza ribonukleinovykh kislot v iadrakh i tsitoplazme kletok pecheni polovozrelykh krys-samtsov

Ethionine did not affect but actinomycin D inhibited the increase in DNA-like RNA synthesis (precursor of ribosomal RNA in nuclei and rRNA in cytoplasm of liver tissue cells of adult male rats), which was caused by single administration of hydrocortisone or protamine-Zn-insulin and by both hormones. The data obtained suggest that the effect of these hormones on the synthesis of DNA-like RNA was realized at the stage of transcription.

[Effect of hydrocortisone and insulin on the synthesis of ribonucleic acids in the nuclei and cytoplasm of the liver cells of sexually immature male rates]. / Vliianie gidrokortizona i insulina na sintez ribonukleinovykh kislot v iadrakh i tsitoplazme kletok pecheni nepolovozrelykh krys-samtsov

A prolonged (within 4 days) administration of hydrocortisone or protamin-Zn-insulin into preadolescent male rats with body weight of 70-90 g caused a distinct increase in the synthesis of DNA-like RNA, precursor of ribosomal RNA in nuclei and ribosomal RNA in cytoplasma of liver tissue. Protamin-Zn-insulin, after simultaneous administration with hydrocortisone, suppressed the increase in the synthesis of liver RNA fractions studied. The data obtained suggest that DNA-like RNA, precursor of ribosomal RNA from nuclei and ribosomal RNA from cytoplasma of liver tissue of preadolescent male rats participate in the synthesis of transaminases in liver tissue. The signigicant role of androgenes was assumed to consist in carring out the inducing effect of glucocorticoids and insulin, which influenced to a variable degree the synthesis of DNA-like RNA, of ribosomal RNA precursors from nuclei and of ribosomal RNA from liver tissue cytoplasma in preadolescent and adult animals.

Prolonged administration to male sexually-mature rats weighing 180-200 g of hydrocortisone, protamine-zinc-insulin enhanced considerably the synthesis of DNA-like RNA, precursor of ribosomal RNA in the nuclei and ribosomal RNA in the cytoplasm of the liver; this increase was even more pronounced after the administration of both hormones. The data obtained were in favour of the participation of DNA-like RNA, precursor of ribosomal RNA of the nuclei and ribosomal RNA of the cytoplasm of the liver of male sexually-mature rats in the synthesis of transaminases of their liver.
