Leukotrienes increase glucose and lactate output and decrease flow in perfused rat liver. 1988

Institut für Biochemie, Universität Göttingen, Germany.

In isolated perfused rat liver leukotriene C4 and D4 but not B4 and E4 enhanced glucose and lactate output and lowered perfusion flow similar to the thromboxane A2 analogue U46619, extracellular ATP and prostaglandin F2 alpha. The kinetics of the metabolic changes caused by leukotriene C4 and D4 resembled those effected by U46619 and ATP but not those elicited by prostaglandin F2 alpha; the kinetics of the hemodynamic changes were similar only to those caused by U46619. The results show that leukotrienes could be important modulators of hepatic metabolism and hemodynamics and point to a complex intra-organ cell-cell communication between non-parenchymal and parenchymal cells.

A family of prostaglandins that includes three of the six naturally occurring prostaglandins. All naturally occurring PGF have an alpha configuration at the 9-carbon position. They stimulate uterine and bronchial smooth muscle and are often used as oxytocics. PGF
