The reliability of a rabbit polyclonal antibody against muramidase to identify monocytes/macrophages in swine was evaluated by immunostaining of cell smears and formaldehyde-fixed, paraffin-embedded tissue sections. Blood in tissue sections, cell smears (peripheral blood, buffy coat, and isolated
BACKGROUND
Muramidase and lactoferrin are important components of the antimicrobial defense system. Muramidase has the ability of opsonization and immunopotentiation and therefore a close relation to the lymphatic tissue. Till now there are only immunohistochemical and microbiological studies on the
The ultrastructural and immunohistochemical features of a primary tumor of the ileum showing the classic histologic features of an inflammatory fibroid polyp (IFP) of the gastrointestinal tract are presented. Ultrastructurally the proliferating cells showed a combination of fibroblastic and
A spectrum of giant cell lesions was evaluated for muramidase, alpha-1 antitrypsin, alpha-1 antichymotrypsin, and S-100 protein immunoreactivity using an avidin-biotin-complex immunoperoxidase method. Peripheral giant cell granuloma, central giant cell granuloma, giant cell tumor, osteitis fibrosa
An 11-year-old patient with inflammatory fibrous histiocytoma of the iliac bone is presented. In addition to routine histopathological procedures the lesion was studied by enzyme-histochemical and immuno-histochemical methods. The results of acid phosphatase, alpha-naphthyl-acetate esterase and
The bactericidal and bacteriolytic effects of lysolecithin (LL) and egg-white lysozyme (LYZ) on Staph. aureus and group A streptococci and the solubilization of phospholipids from the bacterial membranes by these agents was studied. Low concentrations of lysolecithin (1--10 microgrames/ml) are
The pathogenesis of middle ear inflammation caused by Streptococcus pneumoniae was explored in the chinchilla model with different pneumococcal cell wall (CW) preparations, including isolated native CW, M1 muramidase CW (M1-CW) digest, amidase CW digest, and M1 peptidoglycan (M1-PG) digest.
Two patients with inflammatory meningeal masses were studied. Lesions in both patients showed varying proportions of meningothelial and inflammatory components. The non-neoplastic nature of the inflammation was confirmed in one case by lymphocyte surface marker study, which showed T and B cells in
Lipoteichoic acid (LTA) is a surface-associated adhesion amphiphile from Gram-positive bacteria and regulator of autolytic wall enzymes (muramidases). It is released from the bacterial cells mainly after bacteriolysis induced by lysozyme, cationic peptides from leucocytes, or beta-lactam
The literature dealing with the biochemical basis of bacteriolysis and its role in inflammation, infection and in post-infectious sequelae is reviewed and discussed. Bacteriolysis is an event that may occur when normal microbial multiplication is altered due to an uncontrolled activation of a series
We investigated the effect of methylprednisolone on pathophysiological alterations in experimental pneumococcal meningitis. Untreated rats injected with pneumococcal cell wall components after hydrolization with M1 muramidase (PCW-M) developed an increase of regional cerebral blood flow (rCBF; 165.0
Serum lysozyme (muramidase) concentrations were measured in three groups of patients: control, ulcerative colitis and proctitis, and Crohn's disease. The mean +/-SD for each group was: control, 7 +/- 2; ulcerative colitis and proctitis, 7 +/- 2; and Crohn's disease, 10 +/- 4. Although a significant
