following an outbreak of fascioliasis in anzali harbor in 1988, 452 blood samples were collected using a multistage sampling method for hematological and serological studies. after determination of eosinophilia in the samples, antifasciolia antibodies in the sera were also determined using enzyme linked immuno sorbant assay (elisa) and counter-current immuno electrophoresis (ccie). 64.2% of the...

Aim: To compare the results of DNA amplification by the polymerase chain reaction (PCR) with immunofluorescence staining for detecting Pneumocystis carin'i in bronchoalveolar lavage specimens taken from symptomatic HIV seropositive patients with suspected P carinii pneumonia (PCP). Methods: Bronchoalveolar lavage specimens were obtained from 28 symptomatic HIV seropositive patients. Specimens w...

Purpose To investigate intraocular expression of COL7A1 and its protein product type VII collagen, particularly at the accommodation system. Methods Eyes from 26 human adult donors were used. COL7A1 expression was analyzed in ex vivo ciliary epithelium by microarray. Type VII collagen distribution was examined by Western blot analysis, immunohistochemistry. and immuno-electron microscopy. R...

A large number of Streptomyces bacteria with antifungal activity isolated from samples collected in the Trondheim fjord (Norway) were found to produce polyene compounds. Investigation of polyene-containing extracts revealed that most of the isolates produced the same compound, which had an atomic mass and UV spectrum corresponding to those of candicidin D. The morphological diversity of these i...

HCV is a positive strand RNA virus, and is a member of the Family Flaviviridie. HCV show substantial nucleotide sequence variability distributed throughout the viral genome, particularly the HVR1 region that is suggested to be immunogenic in humans. HVR1 is the most heterogeneous region within the E2 genome and peptide corresponding to this region, can be detected by homologous sera. To study t...

Production of immuno and biologically active erythropoietin was documented to occur in the human hepatoblastoma cell line HepG-2. The expression of the erythropoietin gene was further verified by Northern blot analysis using a single stranded RNA probe. In vitro studies showed that erythropoietin production by these cells was not stimulated by hypoxia or cobalt chloride, but was related to the ...
