abstract：:Blood leukocyte count alterations induced by PAF-acether in anesthetized and nonanesthetized rats were investigated. Intravenous injection of increasing amounts of PAF-acether (1.5-8 micrograms/kg) in nonanesthetized animals induced dose-dependent hemoconcentration and leukocytosis. The former was apparent within 10 m...
