This work was performed to investigate the effects of brazilin in vitro on mitrogen-induced proliferation, ConA-induced TCGF release and responsiveness to recombinant-induced proliferation, ConA-induced TCGF release and responsiveness to recombinant IL-2 using splenocytes from C57BL/6 female mice. Brazilin (29-80 ng/ml) caused a noticeable increase in TCGF production of splenocytes, but did not affect responsivness to recombinant IL-2, the expression of ConA-induced high affinity IL-2 receptor and mitogen-induced proliferation of splenocytes.

The present work was designed to investigate the effects of barzilin on ConAinducedd TCGF release, responsiveness to standardd IL-2, and mitogens-induced proliferation of splenocyte when administered intraperitoneally to 8 week-old C57BL/6 mice for 2 consecutive days. Immunological tests were performed 72 hours after the treatment of brailin. The administration of 50 mg/kg brazilin caused a noticeable increase in TCGF release and responsiveness to standard II-2 but inhibited mitogens-induced proliferation of splenocyte. These results that brazilin is able to modular immunological functions despite of its inhibitory effect on mitogen induced cell proliferation.
