Plasma from a patient with early manifestations of disseminated lupus erythematosus, a prolonged partial thromboplastin time with kaolin, mildly prolonged prothrombin time, and a circulating inhibitor affecting the assay of several clotting factors was investigated. The most sensitive test for...
Increased vascular permeability was studied in the synovium of the rat's stifle joint following mechanical trauma and haemarthrosis. The abnormal permeability was detected by injecting colloidal carbon intravenously and examining the synovial vessels for intra-mural deposits of carbon. The...
Three strains of Pseudomonas aeruginosa have shown unstable resistance to gentamicin and a firm linkage between this property and the size of colonies produced on nutrient agar. The resistant parent cells yield distinctly smaller colonies than the sensitive variants. As a point of clinical...
A comparative study was performed to assess the sensitivity and specificity of counterimmunoelectrophoresis (CIEP) and radioimmunoassay (RIA) for the detection of hepatitis B surface antigen. The 8,823 sera examined included selected reference panels and sera collected from populations with low,...
Four serial specimens over 18 months from a hepatocellular carcinoma associated with hypoglycaemia were studied by light microscopy. Ultrastructural study was possible for two of the specimens. Progressive fatty metamorphosis of the tumour cells was observed. The mechanism postulated was that of...
In the peritoneal cavity of the adult rat mast cells at the four stages of progressive maturation (and corresponding increase of sulphation of granules) are best demonstrated in free peritoneal fluid. Of the 0.1-0.2 × 1 0 6 cells in the free fluid, 26% are at stage 1 of maturation (all granules...
Bacteria isolated from the urine of 400 hospital inpatients and 483 outpatients were identified and the in vitro sensitivity of these organisms against 12 antibacterial agents currently used in the treatment of urinary tract infections was determined. There was little difference in the...
A sequential study has been made of the ultrastructure of local renal graft-versus-host reactions produced in cyclophosphamide-pretreated rats by injection of either allogeneic or xenogeneic (mouse) spleen cells beneath the renal capsule. Early in the reaction, immunoblasts were seen between the...
