SO Int Conf AIDS. 1994 Aug 7-12;10(1):155 (abstract no. PB0048). Unique Identifier : AIDSLINE ICA10/94369480 AB OBJECTIVES: The survival time after SIV inoculation to rhesus monkeys varied from animal to animals. We searched for the parameters that could predict the fate of the monkeys inoculated with SIV. METHODS: SIVmac were inoculated to 8 rhesus and 2 cynomolgus monkeys. Six out of 8 rhesus macaque died of AIDS, while 2 cynomolgus monkeys still alive. Periodical results of serum biochemical analyses, antibody (Ab) titer, CD4/CD8 ratio and autopsy were compared in relation to the predictive values to the end stage of infected monkeys. RESULTS: Analyses of the periodical data of serum biochemical values revealed that elevated alpha 1 acid glycoprotein (alpha 1-AG) level can predict the end stage of the infected monkeys, regardless of their individual symptoms. Moreover, the increase in plasma alpha 1-AG was observed as the earliest sign among serum protein alterations at the end stage of AIDS monkeys. We also found that alpha 1-AG increased immediate after SIV infection prior to the raise of the Ab to SIV without exceptions. CONCLUSION: The elevated plasma level of alpha 1-AG could be the sign for the successful inoculation of SIV in early stage and also be the signal to predict the end stage of the SIV infected monkeys.
