The present study demonstrates the occurrence of substance P (SP)- and calcitonin gene related peptide (CGRP)-immunoreactive nerve fibres in bone, bone marrow, periosteum, synovial membrane and soft tissues adjacent to the bone. The distribution pattern of the two types of nerves was similar, although the CGRP-positive fibres generally were more numerous.(More)
The occurrence of autonomic nerves in the lumbar spine of rats was investigated by immunohistochemical technique. Both peptidergic nerves, represented by immunoreactivity to neuropeptide Y (NPY), vasoactive intestinal polypeptide (VIP), and noradrenergic nerves as reflected by tyrosine hydroxylase (TH) immunoreactivity, were identified. NPY- and TH-positive(More)
The present study in the rat demonstrates the feasibility of applying immunohistochemical staining techniques on bone tissue for studies of substances such as neuropeptides contained in nerve fibers. Two fixation procedures, as well as the influence of demineralization on neuropeptide antigenicity, were studied in bone and for comparison in small(More)
We suggest that different mechanisms underlie joint pain at rest and on movement in osteoarthritis and that separate assessment of these two features with a visual analogue scale (VAS) offers better information about the likely effect of a total knee replacement (TKR) on pain. The risk of persistent pain after TKR may relate to the degree of central(More)
The presence of sensory and autonomic nerves in the synovial membrane of the lumbar facet joint in rats was investigated by immunohistochemistry. Substance P and calcitonin gene-related peptide immunoreactivities, representing sensory nerves, were observed as varicose fibers in the synoviocyte layer. The fibers were predominantly nonvascular. The autonomic(More)
The present paper comprises a review of the literature on chondromyxoid fibroma (CMF) and a report on nine cases originally classified as CMF, found in a review of all curetted bone lesions at our department from 1955 to 1978. At histologic revaluation only two cases fulfilled the criteria for true CMF, whereas six were classified as other benign bone(More)
The occurrence of the neuropeptides vasoactive intestinal polypeptide (VIP) and neuropeptide Y (NPY) in ankle joints and dorsal root ganglia (L2-L6) was analyzed in normal and arthritic Lewis rats. In addition the effect of capsaicin pretreatment was investigated. The study included 92 rats consisting of 4 groups, 23 rats in each; normal rats, normal rats(More)
The effect of four different neuropeptides and norepinephrine (NE) on cyclic AMP formation in four different osteoblastic cell lines and in isolated neonatal mouse calvarial bone cells has been examined. In the rat osteosarcoma cell line UMR-106-01, vasoactive intestinal polypeptide (VIP, 0.001-1 microM), calcitonin gene-related peptide (CGRP, 0.3-30 nM),(More)
In a retrospective study of all 137 patients with soft-tissue sarcoma treated by surgery between 1972 and 1984, the clinical course was related to several host and tumour features, including the Surgical Staging System of Enneking, Spanier and Goodman (1980). Only patients free from metastasis with untreated primary lesions on admission were included.(More)
Lymphocyte-mediated lysis of autologous tumor cells (autologous lymphocyte cytotoxocity ALC) was tested at the time of surgery in 108 patients (46 squamous cell carcinomas of the lung, 25 adenocarcinomas of the lung, 19 soft tissue sarcomas and 18 osteosarcomas). The clinical course of these patients in relation to the test results has been published(More)
