Inflammatory bowel disease mucosal biopsies have specialized lymphokine mRNA profiles.
Drumming improves immunity: Group drumming resulted in increased dehydroepiandrosterone-to-cortisol ratios, increased natural killer cell activity, and increased lymphokine-activated killer cell activity without alteration in plasma interleukin 2 or interferon-gamma, or in the Beck Anxiety Inventory and the Beck Depression Inventory II.
For example, chrysotile fibres have been shown to depress the in vitro proliferation of phytohemagglutinin-stimulated peripheral blood lymphocytes, suppress natural killer cell lysis and significantly reduce lymphokine-activated killer cell viability and recovery.
At the same time it increases the cytotoxic action of macrophages in destroying tumor cells by stimulating the production of lymphokine interleukin.
"It certainly has stimulated the immune systems," Clyde said as he continued to study the lymphokine chart.
They may be named by their source: lymphokine (cytokines made by lymphocytes) monokine (cytokines made by monocytes) chemokine (cytokines with chemotactic activities) interleukin (cytokines made by one leukocyte and acting on other leukocytes).
