Unique Identifier : AIDSLINE ICA10/94369377 AB OBJECTIVE: Glycyrrhizin (GL), one of the plant extracts, have been evaluated for their inhibitory effect on HIV replication. From these observations, we attempted to use GL in murine AIDS (MAIDS) model and evaluated the development of MAIDS. METHODS: C57BL/6 mice were inoculated with LP-BM5 MuLV. Treatment with GL was began 0 day or 4 weeks after the virus inoculation, three times a week until 19 weeks. For monitoring the appearance of MAIDS, the spleen weight and axillary lymph node weight were measured. The immunological abnormalities were monitored with respect to the mitogenic response of spleen cells to Con A and LPS. Serum IgM levels were also determined. RESULTS: All mice infected with the virus alone developed MAIDS and died until 15 weeks after infection. GL had no effect on the 50% of mortality, although some mice that began the treatment on 4 weeks from virus inoculation were survived until 17 weeks. The splenomegaly and lymphadenopathy of mice treated GL were suppressed, compared with mice inoculated virus alone. The mice with no signs of disease had a normal Con A response, but did not show a LPS response. The mice with MAIDS had elevated levels of serum IgM. GL did not lower the levels of serum IgM even in these treated mice. CONCLUSIONS: These results suggested that the treatment of GL was considerably effective to MAIDS mice in preventing the progression of disease, although GL did not completely prevent their mortality.
