Content of trace elements in the lymph and blood during pyrogenal-induced fever and complete freund's adjuvant-induced low-grade fever.
Experiments on rats showed that complete Freund's adjuvant-induced low-grade fever and pyrogenal-induced fever are accompanied by an increase in the content of Mn, Cu, Zn, and Se in the thoracic duct lymph. Our results indicate that the lymphatic system supplies trace elements to the circulation, which compensates for a deficiency in trace elements and maintains their systemic circulation. The decrease in the content of some trace elements in the blood during fever is probably associated with their excessive consumption (e.g., to maintain the antioxidant defense system). During experimental low-grade fever and pyrogenal-induced fever, the lymphatic system serves as the reservoir for trace elements and plays a role in the regulation of trace element balance in biological fluids.
