In the present work, polys tyrene (Ps) doped with Rhodamine 6G was prepared. The infrared absorption spectra were obtained and dis c u s s e d in the range (400-4000 cm ). A new band appeared -1 2 at 3300 cm due to NH in the spectra of PSRhodamine 6G. In the spectra of Ps – Rhodamine 6 -1 G this band appeared at 1599 ass igned to C = O s tretching vibration. This is due to interaction between t...

The histologic changes associated with the development of the acute inflammatory response to experimental cutaneous mucormycosis were studied at various times from 5 minutes to 24 hours after inoculation into normal rabbits and in rabbits with acute alloxan diabetes and acidosis. In normal animals the response by polymorphonuclear leukocytes began within a few minutes after inoculation, increas...

CONTEXT Although Helicobacter pylori infection is prevalent in our country, there are few studies evaluating the associated histological abnormalities in children. OBJECTIVE To evaluate the histological features of the gastric mucosa in children and adolescents with Helicobacter pylori gastritis. METHODS One hundred and thirty two gastric biopsies from 22 symptomatic patients infected with ...

OBJECTIVES High-yield isolation and purification of human leukocyte subpopulations from whole blood is fundamental to many biological and medical applications including qualitative and quantitative PCR-based techniques of determining human cytomegalovirus infection. Several procedures have been reported to purify morphologically and functionally intact human leukocyte subpopulations for diagnos...

Morphological and metabolic observations have been made on the effects of endotoxin, deoxycholate, and digitonin (at less than 50 microg/ml) on polymorphonuclear leukocytes and mononuclear cells. The agents stimulate the respiration and glucose oxidation of these cells in a manner similar to that seen during phagocytosis. Electron microscopy revealed no morphological changes with the first two ...

The effects of intra-articular methotrexate (MTX) were compared with saline in 20 patients with persistent knee effusions due to rheumatoid arthritis (15) and psoriasis (5) in a double-blind pilot study. Clinical improvement was seen in most patients given either MTX or saline and was attributed to joint irrigation during arthroscopy and the placebo effects. MTX had a local anti-inflammatory ef...

Mononuclear cells from rabbit joint fluid were studied after synovitis was induced by various means, including the intra-articular injection of bacterial endotoxin or of aggregated human gamma globulin in normal rabbits, or of HGG in rabbits previously sensitized to this material. The large majority of mononuclear cells in all groups were monocytoid rather lymphocytoid, and these cells were mos...
