The general time course of the in vivo studies. The time of repletion and immune response assays varied somewhat among experiments. Animals were injected with extract, mouse rIL-2, or normal saline (for control group) for 5 days. Half of the animals (total of 30 mice) were sacrificed on days 6 and the remaining animals (the remaining 30 mice) were sacrificed on day 16.
