Nucleosomes and nonribosomal RNA transcription in early mouse embryo. An electron microscopic study.

Zygotes from hyperovulated albino-mice isolated during the first several cleavages were spread according to the method of Miller and Bakken [28] in the presence and in the absence of Joy or in the presence of Sarcosyl. Our results show that: 1. already before the first division of the mouse zygote all chromatin is organized in nucleosomes, 2.

[Our experience with the dialysis treatment of phalloides fungal poisoning].

The authors present their practical experience in the treatment of phalloid fungal intoxication via dialysis methods of treatment, included within the complete therapeutic system of that kind exogenous intoxication. The peritoneal dialysis and hemodialysis, with consideration given to the patient's state, enables the reduction of the extremely high lethality. Their early application guarantees higher effectiveness of the dialysis methods of treatment.

[Estrus induction in sheep injected with colostrum at different phases of the sexual cycle].

Investigations on the mechanism of colostrum effect in sheep sex apparatus stimulation were carried out. The experiments included 57 sheep, 10 of them used as a check and the remaining 47 distributed in four treatment groups and injected with colostrum at various phases of the sex cycle. It was established that the effectiveness of injecting cow colostrum on sheep with the aim of inducing synchronous oestrus during the regular reproduction season depends on the sex cycle phase at which the injection takes place.

[Correlation of heredity and environmental factors in the etiology of Vilyui encephalomyelitis. I. Patient frequency in families].

Viljuisk encephalomyelitis (VE) is a severe neurologic disease characterized by slow progressive dementia', oligobradykinesia, low spastic paraparesis and speech disturbances. It develops in persons of 20-50 years old. VE occurs in a small region of middle Viljui, but for last years the focus has considerably expanded.

[Effect of the lighting intensity on the raising of broiler turkey poults].

Experiments were carried out with turkey poults of the Ten 30 breed with the purpose to establish the changes in some hematologic and biochemical indices that had taken place under the influence of illumination intensity. It was found that the light regime influenced hemopoiesis as well as the intensity of metabolism. Both the hemoglobin content and the erythrocyte count were higher at illumination of higher intensity.

[Secondary hemorrhage following trauma to the bones and soft tissues of the extremities].

An analysis of 16 cases of secondary hemorrhages in injuries of bones and soft tissues of the extremities is presented. The secondary hemorrhages occurred within the period from 16 hours to 27 days after the trauma. Angiographic study is a valuable adjunct for establishing the correct diagnosis.
