The proliferation indices (PIs) were determined in 33 meningiomas using two monoclonal antibodies to the Ki-67 antigen (Ki-67 and MIB1). PIs obtained using Ki-67 on frozen material were intermediate between the lowest and highest MIB1 PIs determined in paraffin wax sections. Preoperative embolisation did not influence Ki67 PI, but four of the 15 embolised tumours showed substantially increased ...
Rabbits were inseminated artificially and inoculated 1 week later with rubella virus. The attenuated vaccine strain HPV-77 or strain 67-1127 which had been through 12 cell culture passages was used. Half of the rabbits in each group had been inoculated 1 month prior to insemination with the corresponding strain. Evidence of infection induced by either strain was obtained by immunofluorescence i...
Background and Objectives: Uterine smooth muscle tumors are the most common human neoplasm .They are divided clinically as benign and malignant but there is another group of lesions which is difficult to place in these two categories ,so-called smooth muscle tumors of uncertain malignant potential (STUMP) and differentiation of these tumors on the basis of H&E staining is impossible . Th...
We investigated 31 cases of pleomorphic carcinomas of the lung, with a double component of neoplastic epithelial cells and of spindle and/or giant cells. To correlate the morphologic diversity of these two cell components with their immunophenotype, we evaluated the expression of several gene products involved in cell differentiation (cytokeratins, epithelial membrane antigen, carcinoembryonic ...
During a period of one year all of 105,724 blood donations were tested for Australia (Au) antigen and its antibody by rapid immunoelectro-osmophoresis-86 (1 in 1,229) were positive for antigen and 67 (1 in 1,578) positive for antibody. Second donations by previously negative donors reduce the overall incidence of positives. Men prisoners have a significantly higher incidence of Au antigen (1 in...
The present study was carried out for the antigen detection of Feline panleukopenia virus (FPV) in diarrhoeic cats referred to the Veterinary Clinic of the School of Ahvaz University, in southwest Iran. Faecal samples were collected from 67 diarrhoeic household cats during 2005 to 2007. According to the age and clinical signs, the cats were divided into two groups; 6 months, hemorrhagic and ...
