An 82-year-old woman presented with severe bleeding due to antibodies inactivating both human and porcine factor VIII. Treatment with porcine factor VIII was successful in correcting the hemorrhagic manifestations, despite the fact that subsequent studies showed that the baseline porcine inhibitor titer was greater than the human inhibitor titer. Anamnestic response to porcine factor VIII did n...

The virus neutralization (VN) test was used to determine potency of the infectious bronchitis (IB) vaccine. The results of VN, hemagglutination inhibition (HI), and enzyme-linked immunosorbent assay (ELISA) were compared with those of the IBV M41. The r values between VN and HI titers and the ELISA antibody titer were 0.8782 and 0.0336, respectively, indicating a high correlation between VN and...

A new method has been developed for determination of the species of origin of denatured bloodstains. Antiserum with known titer is incubated with the denatured bloodstain. If the bloodstain has the same origin as the antiserum, a substantial amount of antibody will be absorbed by the stain, resulting in an attenuation of the antiserum titer. By reacting the supernatant with a known serum by usi...

Evaluation of Two Sources Plant Antioxidants on Antioxidant Status, Morphology Changes the Jejunum, Antibody Titer Against Influenza and Growth Performance Broilers

BACKGROUND Measurement of the ABO antibody (Ab) titer is important in ABO-incompatible transplantation. However, to the best of our knowledge, no standard protocol or external survey program to measure the ABO Ab titer has been established in Korea. We investigated the current status of ABO Ab titer measurements at various laboratories in Korea and the impact of the protocol provided to reduce ...

BACKGROUND Even though renal transplantation across blood groups is not uncommonly practiced nowadays, there is still hesitation regarding ABO-incompatible transplantation with very high baseline antibody titer. In this case report, the outcome of an ABO-incompatible kidney transplant recipient with a high baseline isoagglutinin titer is reported. CASE REPORT The patient was a non-diabetic, 33-...

Banked acute-phase and convalescent-phase serum samples from a previous study of respiratory illness in university students were examined for significant (>/=2-fold) increases in ELISA titers of IgA and IgG antibody to Bordetella pertussis filamentous hemagglutinin, pertactin, and fimbriae-2 and >/=4-fold titer increases to agglutinogens by agglutination. ELISA titers of antibody to pertussis t...

After intracerebral inoculation of mice with a 10 per cent suspension (approximately 2000 LD(50)) of the Lansing strain of poliomyelitis virus, the infectivity titer in the brain decreased for approximately 6 hours. It then rose rapidly for 12 to 18 hours to reach titers of over 10(-4). The rise in titer in the spinal cord closely paralleled that in the brain for 18 hours, after which the titer...
