Distribution, structure and projections of the frog intracardiac neurons.

Histochemistry for acetylcholinesterase was used to determine the distribution of intracardiac neurons in the frog Rana temporaria. Seventy-nine intracardiac neurons from 13 frogs were labelled iontophoretically by the intracellular markers Alexa Fluor 568 and Lucifer Yellow CH to determine their structure and projections. Total neuronal number per frog heart was (Mean ± SE) 1374 ± 56.

Topography of the porcine epicardiac nerve plexus as revealed by histochemistry for acetylcholinesterase.

The aim of the present study was to map the topography of the porcine epicardiac nerve plexus (ENP) and to re-examine the total number and distribution of the porcine intracardiac ganglia and neurons. Eleven juvenile pigs (Sus scrofa domestica, 3-4 weeks of age) were examined employing histochemistry for acetylcholinesterase to reveal the ENP on total hearts. The nerves entered porcine epicardium at five sites: (1) ventro-medially to the origin of the superior vena cava, (2) dorsally to the origin of the superior vena cava, (3) among the pulmonary veins, (4) dorso-medially to the origin of the left azygos vein, and (5) ventrally to the left pulmonary vein.

[Distribution of the epicardiac neural ganglia in human fetuses of different age].

Objective: The epicardiac neural ganglia of the adult human heart are distributed in the seven neural ganglionated subplexuses. The aim of the present investigation was to determine the distribution of the epicardiac ganglia in human fetuses of different age, because intrinsic cardiac nervous system of the human fetus has not been enough investigated so far.

Material And Methods: In the present study seventeen human fetus hearts were investigated, in which epicardiac neural ganglionated plexus was visualized by histochemical method for acetylcholinesterase.

Morphology of the intrinsic cardiac nervous system in the dog: a whole-mount study employing histochemical staining with acetylcholinesterase.

The intrinsic cardiac nervous system is known to be important both in the prevention and treatment of risky heart diseases. The present study was designed to determine the topography and 3-dimensional architecture of the intrinsic nervous system in the canine heart highlighting the differences of this system in dogs and humans. The morphology of the intrinsic cardiac neural plexus was revealed with a histochemical method using acetylcholinesterase in whole hearts of 18 mongrel dogs and examined with the aid of dissecting stereoscopic and contact microscopes.

Morphology, distribution, and variability of the epicardiac neural ganglionated subplexuses in the human heart.

Concomitant with the development of surgical treatment of cardiac arrythmias and management of myocardial ischemia, there is renewed interest in morphology of the intrinsic cardiac nervous system. In this study, we analyze the topography and structure of the human epicardiac neural plexus (ENP) as a system of seven ganglionated subplexuses. The morphology of the ENP was revealed by a histochemical method for acetylcholinesterase in whole hearts of 21 humans and examined by stereoscopic, contact, and bright-field microscopy.

Anatomical study of the neural ganglionated plexus in the canine right atrium: implications for selective denervation and electrophysiology of the sinoatrial node in dog.

The aim of the present study was to elucidate the topography and architecture of the intrinsic neural plexus (INP) in the canine right atrium because of its importance for selective denervation of the sinoatrial node (SAN). The morphology of the intrinsic INP was revealed by a histochemical method for acetylcholinesterase in whole hearts of 36 mongrel dogs and examined by stereoscopic, contact, and electron microscopes. At the hilum of the heart, nerves forming a right atrial INP were detected in five sites adjacent to the right superior pulmonary veins and superior vena cava (SVC).

Morphological study of neurons in the nerve plexus on heart base of rats and guinea pigs.

The paper describes the morphological pattern of neurons in the nerve plexus on the heart base of rats and guinea pigs. The nerve plexus, containing the investigated neurons, lies beneath the pulmonary arteries on the myocardium of the left atrium. This plexus is not covered by the epicardium.

[Tissue micro-diastasis and closed micro-cavities of the surgical zone in glaucoma surgery].

Investigation of methods of antiglaucoma surgery in order to control the cicatrization of filtration routes of intraocular fluid discharge is carried out at the Vladivostok Medical Institute since 1989. A total of 662 operations are analyzed, which were carried out using an original method with "inverted trapezium"-shaped dissection of the deep tissues of the sclera. A microsurgical knife designed by the authors and patented was used.

[The etiotropic and pathogenetic treatment of patients with chronic gastritis and primary chronic gastroduodenitis].

120 patients with chronic gastritis and primary chronic gastroduodenitis were given a three-week course of etiopathogenetic treatment (antichelibacterial and immunocorrective drugs) that allowed to diminish the clinical, bacteriological and immune manifestations of the disease and achieve a complete cure in most patients. Patients with marked chelibacteriosis revealed greater refractoriness. The authors recommend prolonged courses of treatment with alternations of etiologically directed drugs.

[The dynamics of the organic antibodies during treatment in patients with chronic diseases of the liver and the pancreas].

Organ antibodies were studied after immunothermistometry treatment in 205 patients with chronic diseases of the liver. One group of patients was treated by routine methods in accordance with the diagnosis, while the second group of patients was additionally given hemodes. Before treatment organ antibodies were revealed in 31 patients (70.

[Patterns of the development and progression of age-related cataracts in Voroshilovgrad Province (based on office visit data)].

A 5-year observation over 510 patients with initial senile cataract allowed to attribute to a group of risk relatives of the patients with senile cataract; persons who had suffered endocrine diseases; those with cardiovascular pathology; those who had suffered viral infections, rheumatism, renal and hepatic diseases; such workers, as drivers, founders, smiths, stockers, agricultural workers, teachers, lawyers. After 35 years of age, the patients of the group of risk should be yearly examined by the ophthalmologist. In case of general diseases, the main disease and disturbed turn-over should be treated.
