The present study examines the response of colon-projecting neurons localized in the inferior mesenteric ganglia (IMG) to axotomy in the pig animal model. In all animals (n = 8), a median laparotomy was performed under anesthesia and the retrograde tracer Fast Blue was injected into the descending colon wall. In experimental animals (n = 4), the descending(More)
In regio supraoptica there are nucleus paraventricularis, nucleus supraopticus, area hypothalamica anterior and nucleus suprachiasmaticus. These centers are more developed in hedgehog than in mole and common shrew. Area preoptica is divided into 4 parts (medial, lateral, periventricular and middle) from among the middle part in hedgehog is less developed(More)
The caudate nucleus and the putamen of bison bonasus have been investigated. The Golgi procedure and Nissl stain had been used to reveal their cellular organization. In the Golgi preparation striatal neurons belong to the two fairly divergent main groups in which several types of cells can be distinguished. The first class, comprising the bulk of neuronal(More)
The study describes for the first time the colocalization pattern of calbindin (CB) and cocaine- and amphetamine-regulated transcript (CART) in the mammillary body (MB) and anterior thalamic nuclei (ATN) - structures connected in a topographically organized manner by the mammillothalamic tract (mtt). Immunohistochemical study was performed on fetal (E40,(More)
A subpopulation of the pig inferior mesenteric ganglia (IMG) neurons projecting to the colon exhibit calbindin-like immunoreactivity. It is not known if there are any changes in the chemical coding patterns of these neurons during porcine proliferative enteropathy (PE). To answer this question, juvenile Large White Polish pigs with clinically diagnosed(More)
This study describes for the first time the distribution of the calcium-binding protein calretinin (CR) in the anterior thalamic nuclei (ATN) of the guinea pig during development. Brains from animals ranging from 40th embryonic day (E40) to 80th postnatal day (P80) were used in the study. No CR-immunoreactive (CR-ir) perikarya were present among the ATN at(More)
Our recent studies have shown that the distribution of calretinin (CR) in the anterior thalamic nuclei (ATN) changes significantly during the development of the guinea pig. The present study was designed to reveal the distribution pattern of calcium-binding proteins, i.e. calbindin (CB) and parvalbumin (PV), as well as the colocalization pattern of all(More)
The characteristic features of the common shrew amygdala (CA), as shown by volumetric comparisons of the individual nuclei, are the poor development of the lateral (LA) and basomedial (BM) nuclei as well as the particularly strong formation of the basolateral (BL) and lateral olfactory tract (NLOT) nuclei. The central (CE), cortical (CO) and medial (ME)(More)
The studies were carried out on the hypothalamus of bison bonasus aged 2 and 3 months. Sections were made by means of Bagiński's technique and Nissl and Klüver-Barrera methods. Four types of neurons were distinguished in the paramamillary nuclei: nucleus supramamillaris (Sm) and nucleus tuberomammillaris pars posterior (Tmp). Type I, small and medium-size,(More)
The studies were carried out on the mesencephalons of four European bisons with two different Golgi procedures and stained according to the Nissl and Klüver-Barrera methods. Four types of neurons were distinguished in the substantia nigra of the European bison. Type I are fusiform cells which are most numerous in pars compacta of SN. From each pole of the(More)
