[Effectiveness of a herbal preparation tonsilgon N for the treatment of children presenting with chronic adenoiditis].

The objective of the present study was to estimate the effectiveness of the herbal preparation tonsilgon N exhibiting the anti-inflammatory and immunostimulating properties for the treatment of the children presenting with pathology of a pharyngeal tonsil. A total of 62 children at the age varying from 3 to 11 years with chronic adenoiditis (CA) were available for the examination. The study group was comprised of 32 children, the control one included 30 patients. The study has demonstrated the improvement of daytime nasal breathing in the study group compared with the control patients by 15% on day 5, by 30% on day 7, and by 73% on day 9 after the onset of the treatment. The intensity of rhinorrhea in the children treated with the herbal preparation decreased sooner than in the control group. Nasal breathing at night improved as soon as day 5 after the onset of therapy. However, the difference between the treated and control children was statistically significant only on day 7 whereas night-time nasal breathing on day 9 improved in the study group by 1.4 times compared with the control one. It is concluded that the inclusion of therapy with tonsilgon N in the combined treatment of the children presenting with chronic adenoiditis increases its effectiveness and accelerates the process of reconvalescence. Tonsilgon N is a safe medication suitable for the prolonged application.

[Provisionality phenomenon in the histo- organo- and systemogenesis].

This review summarizes the results of the study of the provisionality phenomenon in the development of the organs of the urinary system (mesonephros, metanephros) in viviparous (human, rat) and oviparous (bird) amniotes, human organs of mixed origin (pituitary, ovary, stomodeum) reparative regeneration of supporting tissues (in humans and Syrian hamster), morphogenesis of primary hepatic cancer developing against the background of superinvasive opisthorchiasis. It is shown that during the development of tissues and organs, the stages of provisional and definitive histo- and organogenesis could be determined; saltatory mechanism is typical for embryonic organogenesis (formation of cartilaginous skeletal primordia, meso- and metanephrons) and foci of oncogenesis. Transformation zones of the type of tissue organization in the epithelium are located in the areas of contacts of the derivatives of different embryonic primordia. Mechanism of transformation of the epithelial layer of stomodeum and Rathke's pouch is provided by local activation of apoptosis and by the formation of the epithelial cells of a qualitatively new generation.

[Morphohistochemical and electrophysiological characteristics of the transverse striated muscles of the rabbit esophagus]. / Morfogistokhimicheskie i élektrofiziologicheskie osobennosti poperechnopolostaykh myshts pishchevoda krolika.

A specific histochemical profile of the muscular tunic of the stomach has been revealed; its myons demonstrate a high succinate dehydrogenase and myofibrillar ATPase activity. Electrical activity of the oesophageal musculature has common features with biopotentials of the skeletal muscles and the smooth musculature of the stomach. The similiarity with the skeletal muscle biopotentials is evident as a peculiar spike activity, especially at the time of feeding. In electrograms of the striated oesophageal muscles slow waves are seen; they change at deprivation and feeding. Therefore, it is possible to compare them with the smooth musculature capable to generate slow waves.

[Morphohistochemical characteristics of structures of the esophageal cross-striated muscle tissue]. / Morfogistokhimicheskie osobennosti stroeniia poperechnopolosatoi myshechnoi tkani pishchevoda.

On the bases of histochemical enzymatic studies and morphometric investigations, some differences were revealed between cross-striated esophageal muscular tissue and other skeletal muscles of mammals. A peculiar feature of the esophageal musculature is prevalence of unitypical fibres with small diameter and possessing high activity of oxidating enzymes. According to these signs, esophageal myons can be ascribed to the first type of muscular fibres. Simultaneously, a high activity of myofibrillar ATPh is revealed in them. Thus, according to histochemical indices, cross-striated esophageal muscular fibres of mammals are quick and slowly fatiqued fibres.
