Serum and immunoglobulin preparations obtained from sharks are used to prepare compositions, including pharmaceutical compositions, for inhibiting retrovirus replication in susceptible cells. Thus, the serum preparations are useful for inhibiting diseases associated with retroviral infection, such as acquired immunodeficiency syndrome. The serum concentrates and immunoglobulins therefrom are also used to inhibit growth of tumor cells, especially sarcomas and leukemias. |
