Abstract
Inflammatory stress as characterized by infection withStreptococcus pneumoniae, administration of endotoxin, or the induction of a turpentine abscess is characterized by the inhibition of the ketosis associated with fasting and a decline in the level of free fatty acids in the plasma. Moreover, rats subjected to these inflammatory stresses demonstrate a significant rise in peripheral and portal insulin and glucagon. Rats subjected to noninflammatory stresses, screen-restraint, or noninvasive femoral fracture did not demonstrate the inhibition of ketosis but did show a decrease in plasma free fatty acids. The noninflammatory stresses did not show an abnormal elevation of plasma or portal insulin or glucagon.
