Conversion of fused hips to low friction arthroplasty.
Fifty-four hips converted to low friction arthroplasty between 1965 and 1975 have been reviewed one to eleven years after operation. In many cases malposition had led to degenerative changes in the opposite hip, the lumbar spine or the knee, often with severe loss of function due to pain. It was found that total replacement could give useful relief of pain and improved function, though the range of movement obtained was not as good as in primary replacement. An outstanding feature was the correction of inequality of leg length. In general, the results were much better in cases of ankylosis acquired in adult life than in cases of spontaneous fusion after sepsis in childhood. The most important complication was a single case of sciatic palsy.

Are gamma delta T cells important for the elimination of virus-infected cells?
Rhesus monkeys (Macaca mulatta) gamma delta T cells were identified using a monoclonal antibody. The relative representation of gamma delta T lymphocytes in the peripheral blood, lymph nodes, and spleen resembles that of Homo sapiens. The analysis of function and specificity revealed further significant similarities between the simian and human gamma delta T-cell systems. Since both human and monkey gamma delta T lymphocytes can effectively lyse cells infected with immunodeficiency viruses, it is possible that the primate gamma delta T-cell systems contribute to antiviral immunosurveillance.

Pathogenesis of SIVmac251 after atraumatic inoculation of the rectal mucosa in rhesus monkeys.
Intrarectal inoculation of rhesus monkeys with low doses of SIVmac led to a prolonged clinical and virological latency that was not observed for high intrarectal doses or for intravenous inoculation. Animals infected intrarectally with low virus doses remained negative for serum antibody responses to SIV for at least one year even though they readily transferred SIV to naive recipients via transfusion of whole blood.
