摘要

Controlled immunological shock, induced by bioincompatible material apheresis for cancer (BIC MAC) therapy, produces an immunoactive status in experimental subjects. However, in order to provide a safe, painless, effective, and reproducible BIC MAC therapy, it is mandatory to provide general anesthesia with endotracheal intubation not only during apheresis procedures of 1-h duration but also for an additional 5?h. Using this procedure, there was no mortality experienced during animal experiments. Also, there were no procedurally related physical or sensory abnormalities demonstrated. This general anesthesia of 6?h covered not only the initial 30?min of the hypotension and hypoxic stages but also the recovery stages to hemodynamically normalize the experimental animals. After 6?h, the accumulated leukocytes in the lung are released back to the systemic circulation. In general, granulocytes decreased almost 100% while lymphocytes decreased only 40–50%. During these 6?h, increases of cytokines (tumor necrosis factor-, interleukin-6, etc.) sometimes up to 1000 times occurred. After the 6-h procedure, leukocytes returned nearly to preoperative levels but tended to be continuously increased. After the fourth day, leukocyte counts more than doubled. These cellular and humoral activations were normalized after 2 weeks. These studies were conducted on six normal mongrel dogs. Currently, similar studies are planned to be conducted on tumor-bearing experimental animals. This procedurally induced immunoactivation by apheresis may be able to produce effective apoptosis in malignant tumor cells.
