Intramuscular hemangiomas are idiopathic lesions which are either tumoral or developmental in origin. A close association of abnormal blood vessels with nerve fibers is found and may suggest that nerves have a primary inciting role in the development of these lesions. In the current study, the number of nerve fibers in different zones around the tumors, as well as the type of neuropeptides present in these fibers, was quantitatively assessed by computer-assisted image analysis of immunohistochemical staining of histological slides. The number of nerve fibers as determined by positive staining by anti-protein S-100 antibodies was found to be elevated in the immediate vicinity of the abnormal blood vessels. The density of the nerve fibers rapidly declined with increasing distance from the hemangiomas, reaching normal values at distances of over 2 mm. Furthermore, hemangiomas contain a significantly higher number of calcitonin gene-related peptide (CGRP), substance P, and Met-enkephalin-positive fibers. The most significant rise in number is that of CGRP-positive fibers. This neuropeptide is a known mitogen, which could be responsible for the growth of the hemangiomatous blood vessels. Substance P is a nociceptive neurotransmitter and its presence can explain the pain which often accompanies even tiny intramuscular hemangiomas.

Non-hairy and hairy human skin were investigated with the use of the indirect immunohistochemical technique employing antisera to different neuronal and non-neuronal structural proteins and neurotransmitter candidates. Fibers immunoreactive to antisera against neurofilaments, neuron-specific enolase, myelin basic protein, protein S-100, substance P, neurokinin A, neuropeptide Y, tyrosine hydroxylase and vasoactive intestinal polypeptide hydroxylase and vasoactive intestinal polypeptide (VIP) were detected in the skin with specific distributional patterns. Neurofilament-, neuron-specific enolase-, myelin basic protein-, protein S-100, neuropeptide Y-, tyrosine hydroxylase- and vasoactive intestinal polypeptide (VIP)-like immunoreactivities were found in or in association with sensory nerves; moreover, neuron-specific enolase-, myelin basic protein-, protein S-100, neuropeptide Y-, tyrosine hydroxylase- and vasoactive intestinal polypeptide (VIP)-like immunoreactivities occurred in or in association with autonomic nerves. It was concluded that antiserum against neurofilaments labels sensory nerve fibers exclusively, whereas neuron-specific enolase-, myelin basic protein- and protein S-100-like immunoreactivities are found in or in association with both sensory and autonomic nerves. Substance P- and neurokinin A-like immunoreactivities were observed only in sensory nerve fibers, and neuropeptide Y- and tyrosine hydroxylase-like immunoreactivities occurred only in autonomic nerve fibers, whereas vasoactive intestinal polypeptide (VIP)-like immunoreactivities was seen predominantly in autonomic nerves, but also in some sensory nerve fibers.

Three patients suffering from an absence of the enteric nervous system are reported. Two sisters presented with severe vomiting shortly after birth and dilatation of the intestine proximal to a stenosis. There was an absence of the enteric nervous system throughout the entire length of the intestine distal to the duodenum. A boy presenting an ileus was found to suffer from an aganglionosis of the entire colon. There was also an absence of neuronal bodies and nerve fibers in the small intestine. The final diagnosis was made by histochemical and immunocytochemical stains for acetylcholinesterase, lactate hydrogenase, neuron-specific enolase, protein S-100, and substance P. In the literature, 13 other patients have been reported. On the basis of differences of symptoms, incidence, sex ratio, genetics, and, presumably, pathogenesis between absence of the enteric nervous system and aganglionosis, it is assumed that the two diseases are separate entities.

The presence of distribution of several neurochemical markers in human fungiform papillae and taste buds were investigated by the immunohistochemical technique. The gustatory cells of the taste buds are in synaptic contact with sensory nerve endings, and considering the taste buds strictly as specialized sensory organs, the amounts and distribution of some of the neurochemical markers were different to what we expected. For example, few structures showed immunoreactivity to the tachykinins substance P (SP), calcitonin gene-related peptide (CGRP), and neurokinin A (NKA) also for the peptides vasoactive intestinal polypeptide (VIP), neuropeptide tyrosine (NPY) and galanin, low amounts of immunoreactivity occurred. On the other hand, using antibodies to protein gene product 9.5 (PGP 9.5), protein S-100, and glutamate, numerous nerve fibres and/or immunoreactive cells were found in the fungiform papillae, in the epithelium, in the connective tissue and around blood vessels, as well as in or near taste buds. Incubation with the antibodies against somatostatin, enkephalin, bombesin, peptide histidine isoleucine amide (PHI), cholecystokinin (CCK)/gastrin and dopamine-beta-hydroxylase (DBH) was negative for the fungiform papillae. In conclusion, the present study has shown several immunoreactive structures using antibodies against certain neurochemical markers. Further investigations will hopefully correlate these morphological findings with functional taste perception data. Future studies of patients with taste disorders or other pathological changes correlated with taste and tongue will also be of utmost importance.

The occurrence and distribution of several neurochemical markers were investigated. Numerous nerve fibres were shown, using antibodies to protein gene product (PGP) 9.5, neurone-specific enolase, calcitonin gene-related peptide (CGRP), substance P. neurokinin A or protein S-100. The presence of vasoactive intestinal polypeptide (VIP), peptide histidine isoleucine amide (PHI), neuropeptide tyrosine, dopamine-beta-hydroxylase (DBH), cholecystokinin/gastrin, glutamate and galanin was more scarce. Nerve fibres containing these above-mentioned markers were found at several locations, i.e. in the epithelium, connective tissue, and around blood vessels. In the taste buds, numerous PGP 9.5, neurone-specific enolase-, CGRP-, substance P-, neurokinin A- and protein S-100-containing structures were found, but few VIP and galanin ones. No immunoreactivity was found with antibodies against somatostatin, bombesin, enkephalin or dynorphin. These findings extend knowledge about the general as well as the neurochemical messenger-based innervation of rat fungiform papillae, forming a firm basis for future functional investigations of normal, experimental and also clinical materials.

Our understanding of the origin of hip pain in degenerative disorders of the hip, including primary osteoarthritis, avascular necrosis and femoroacetabular impingement (FAI), is limited. We undertook a histological investigation of the nociceptive innervation of the acetabular labrum, ligamentum teres and capsule of the hip, in order to prove pain- and proprioceptive-associated marker expression. These structures were isolated from 57 patients who had undergone elective hip surgery (44 labral samples, 33 ligamentum teres specimens, 34 capsular samples; in 19 patients all three structures were harvested). A total of 15,000 histological sections were prepared that were investigated immunohistochemically for the presence of protein S-100, 68 kDa neurofilament, neuropeptide Y, nociceptin and substance P. The tissues were evaluated in six representative areas. Within the labrum, pain-associated free nerve ending expression was located predominantly at its base, decreasing in the periphery. In contrast, the distribution within the ligamentum teres showed a high local concentration in the centre. The hip capsule had an almost homogeneous marker expression in all investigated areas. This study showed characteristic distribution profiles of nociceptive and pain-related nerve fibres, which may help in understanding the origin of hip pain.
