In the different periods of the immune response, the serum and the brain of the same rat were taken to be tested at the same time.Six days after primary antigen stimulating the levels of IgG and IL-2 began to escalate, and 6 days after the antigen restimulating the IgG and IL-2 reached the highest level. After the first two CY injections the levels of IgG and IL-2 began to decline, and after 4 CY injections the IgG and IL-2 reached the lowest level.BSA and CY are ideal agents for establishing immune-enhancing and immune-suppressing animal models. BSA could enhance both the humorous and cellular immune function directly. The CY could directly suppress the cellular immune function, but it could indirectly suppress the humorous immune function.Read More
