Molecular probes were generated to study the expression of tyrosine hydroxylase (TH), choline acetyltrans- ferase (ChAT), galanin (GAL), substance P (SP) and calcitonin gene-related peptide (CGRP) in the peripheral nervous system of the pig with in situ hybridization. Application of the probes to the sections from the inferior mesenteric ganglion (IMG) in control animals revealed numerous neurons...
The present study investigated the chemical coding of neurons in the celiac-superior mesenteric ganglion complex supplying the normal (n = 4) and inflamed (n=4) ileum (chemically-in- duced inflammation) in juvenile pigs using retrograde tracing combined with immunohistochem- istry. Ileum-projecting neurons (IPN) were predominantly distributed in the left and right superior mesenteric pools of the...
Previous immunocytochemical studies provided conflicting data concerning occurrence of the CGRP-immunoreactive neuronal cell bodies in the porcine spinal cord. In the present study, we have investigated expression of the CGRP and its possible coexpression with ChAT in the gray matter of the thoracic, lumbar and sacral spinal cord of the pig. Our study revealed a large number of CGRP-immunoreactive...
Recent decades has brought significant advances in our knowledge of the chemical coding and function of enteric neurons. Calcium ions are important second messenger involved in many aspects of neuron physiology. In the present study, we analyzed immunohistochemically the presence of calcium binding proteins (calretinin and calbindin) in various subpopulations of enteric neurons from the ovine duodenum...
Equine herpesvirus-1 (EHV-1) infections cause significant economic losses for equine industries worldwide as a result of abortion, respiratory illness, and neurologic disease in all breeds of horses. The occurrence of abortions caused by EHV-1 has repeatedly been confirmed in Poland, but neurological manifestations of the infection have not been described yet. Also it is unknown how the infection...
Conantokin G (CTG), isolated from the venom of the marine cone snail Conus geographus, is an antagonist of N-methyl-d-aspartate receptors (NMDARs), the activation of which, especially those located on the central afferent terminals and dorsal horn neurons, leads to hypersensitivity and pain. Thus, CTG blocking of NMDARs, has an antinociceptive effect, particularly in the case of neurogenic pain treatment...
Although resiniferatoxin (RTX) becomes more often used in experimental therapies of sensory system disorders, so far there is no data concerning the influence of RTX on the chemical coding of neurons in dorsal root ganglia (DRG) supplying the urinary bladder in the pig, an animal species considered as a reliable animal model for investigation dealing with human lower urinary tract disorders. Retrograde...
Real-time cell electronic sensing (RT-CES) based on impedance measurements is an emerging technology for analyzing the status of cells in vitro. It allows label-free, real time monitoring of the biological status of cells. The present study was designed to assess dynamic data on the cell processes during equine herpesvirus type 1 (EHV-1) infection of ED (equine dermal) cells and primary murine neuronal...
The study was carried out on three 4-month old female pigs. All the animals were deeply anesthetized and transcardially perfused with 4% buffered paraformaldehyde (pH 7.4). Vestibular ganglia (VG) were collected and processed for double-labelling immunofluorescence method. The preparations were examined under the Zeiss LSM 710 confocal microscope equipped with adequate filter blocks. Neurons forming...
