The incidence of post-operative deep vein thrombosis in general surgical patients of hospital universiti sains malaysia.

The incidence of deep vein thrombosis is believed to be rare in Asians. During recent years, a few reports have appeared with high incidence in orthopaedic patients comparable to Western studies. This study was carried out to find out the incidence of post-operative deep vein thrombosis (DVT) after major surgical procedures in general surgical patients in an Asian population.

Test protocol of an enzyme-linked immunosorbent assay (ELISA) for the detection of antibodies against bovine leukosis virus.

In this communication the test procedure is described for an indirect enzyme-linked immunosorbent assay (ELISA) for the detection of antibodies against bovine leukosis virus (BLV). Test sera are incubated in polystyrene microtiter plates sensitized with a partly-purified preparation of BLV. Bovine antibodies are detected with anti-species immunoglobulin conjugated to the enzyme horseradish peroxidase, followed by the addition of the enzyme substrate.

Studies on bovine leukosis. VII. Further experience with an ELISA for the detection of antibodies to bovine leukosis virus.

An enzyme linked immunosorbent assay (ELISA) and the agar gel immunodiffusion test with bovine leukosis virus glycoprotein as antigen (AGIDT-BLV gp) were further used to test 633 bovine sera for antibodies to BLV. Both tests detected the same number of sera positive (149) or negative (464) for antibodies. Nine sera were negative in the ELISA but found to be weakly positive (2 sera) or bending the control line (7) in the AGDT-BLV gp.

Horse anti-bovine lymphocyte serum. Its effect in calves.

Anti-bovine lymphocyte serum (ABLS) had been prepared in horses with calf thymocytes as antigen and its effects in calves following parenteral administration were studied. The optimal dose was found to be one ml/kg body weight. The ABLS suppressed both the T and B cell functions.
