This study reports on changes in CART-like immunoreactive (CART-LI) nerve structures in the porcine descending colon during chemically driven inflammation and after axotomy. The distribution pattern of CART-LI nerve structures was studied using doublelabeling immunofluorescence technique in the circular muscle layer, myenteric (MP), outer submucous (OSP) and inner submucous plexuses (ISP) and also in the mucosal layer of the porcine descending colon in physiological conditions as well as under pathological factors. In the control animals, CART-LI perikarya have been shown to constitute 5.11% ± 0.64, 4.03% ± 1.17 and 0.05% ± 0.04 in MP, OSP and ISP, respectively. Changes in CART-immunoreactivity depended on the pathological factor and the part of the enteric nervous system (ENS) studied. Numbers of CART-LI perikarya amounted to 2.77% ± 0.64, 2.60% ± 0.36 and 0.26% ± 0.19 during chemically-induced colitis and 3.04% ± 0.88, 2.46% ± 0.8 and 0.43% ± 0.09 after axotomy in MP, OSP and ISP, respectively. Both studied pathological processes also caused an increase in the number of CART-LI nerve fibers in the circular muscle as well as in the mucosal layer.

The tracheal and bronchial parasympathetic ganglia in the cat were studied using the histochemical-tiocholine method of Koelle and Friedenwald and histological techniques. Intensively stained AChE-positive nerve structures, i.e., ganglia and nerve fibres on the wall of the trachea and bronchi, were observed. The ganglia were situated mainly on the dorso-lateral surface of these organs, but they were also present on the ventral surface. The largest ganglia were found in the vicinity of the vagus nerve branches and on the surface of the tracheal smooth muscle. Numerous ganglia (95–210) of different sizes (40 × 230 µm to 260 × 520 µm) and shapes (spindle, longitudinal, oval, elliptical and multiform) were interconnected by nerve fibres and formed a dense ganglionated plexus. The ganglia forming this nerve structure were located mainly on the level of intercartilaginous spaces. They received the nerve branches from the cervical and the upper thoracic branches of vagus nerve and cervical and upper thoracic segments of the sympathetic trunk. Similar AChE-positive ganglionated plexus containing 28–33 ganglia connected by nerve fibres was observed on the posterior wall of the bronchi. Histological investigations confirmed the presence of fascicles of nerve fibers and nerve cells aggregations in the external membrane of the trachea and bronchi. The ganglia consisted of 2–25 cells on the cross-section. They were located mainly on the level of intercartilaginous spaces and contained (except ganglionic neurocytes, nerve fibres) satellite cells and small blood vessels. All the ganglia had thin connective capsule.

The aim of the study was to investigate the expression of biologically active substances in intramural neurons supplying the ileum and large intestines (caecum, spiral colon and descending colon) in normal (control) pigs and in pigs suffering from dysentery. Higher numbers of galanin (GAL)-, vasoactive intestinal polypeptide (VIP)- and calcitonin gene-related peptide (CGRP)-immunoreactive (-IR) neuronal somata were found in the myenteric (MP), and outer (OSP) and inner submucus (ISP) intestinal nerve plexuses in dysenteric pigs as compared to control animals. Additionally, the density of substance P (SP)- and VIP-IR nerve fibres in the studied tissues was higher in dysenteric than in controls animals, whereas the number of CGRP-IR nerve fibres remained unchanged, or even was lower in the experimental pigs. The number of SP-IR nerve cell bodies in the MP of all intestinal segments studied was comparable in dysenteric and control pigs. An increased number of SP-IR perikarya were observed in OSP and ISP of the ileum, cecum and centripetal turns; whereas the number of SP-IR somata was lower in the plexuses of centrifugal turns and the descending colon. The number of nerve fibres found in all layers of the intestinal wall was lower in dysenteric pigs. Each of the intramural plexuses in all the intestinal segments studied contained less than 1% of neuropeptide Y (NPY)-IR neurones and this characteristic was similar both in dysenteric and control pigs. The number of NPY-IR nerve fibres increased slightly in the plexuses as well as in both muscular layers and mucosa.
