Lidocaine inhibits granulocyte adherence and prevents granulocyte delivery to inflammatory sites.

Propranolol antagonizes the anti-inflammatory effect of alcohol and improves survival of infected intoxicated rabbits.

We studied the effects of alcohol and propranolol on the course of peritonitis in rabbits. Induction of sterile peritonitis with normal saline led to a 50% augmentation of granulocyte adherence in normal rabbits, and a mean cumulative granulocyte count of 27,000/mm(3) in peritoneal exudate by 8 h. Rabbits intoxicated with alcohol at the time of peritonitis induction maintained a granulocyte adh...

Reversal of granulocyte adherence to nylon fibers using local anesthetic agents: possible application to filtration leukapheresis.

The effects of the cationic anesthetic agents tetracaine and lidocaine on granulocyte function, morphology, and adherence to nylon fibers were studied in an attempt to improve current methods of granulocyte collection by filtration leukapheresis (FL). When dissolved in acid-citrate-dextrose (ACD) plasma, these drugs significantly increased granulocyte elution from the fibers in a dose-related f...

Lidocaine and its analogues inhibit IL-5-mediated survival and activation of human eosinophils.

Eosinophils and cytokines active on eosinophils, especially IL-5, are believed to be critically involved in chronic allergic diseases. IL-5 activates eosinophils and enhances their survival in vitro by delaying apoptosis. In this study, we found that lidocaine and six analogues blunt responses of eosinophils to IL-5. Lidocaine and its derivatives inhibit IL-5-mediated eosinophil survival in a c...

Impaired granulocyte adherence in multiple myeloma: relationship to complement system, granulocyte delivery, and infection.

Salicylate blockade of granulocyte adherence and the inflammatory response to experimental peritonitis.

Aspirin profoundly inhibited the in vitro augmentation of human and mouse granulocyte adherence to nylon fiber induced by the bacterial products Escherichia coli endotoxin and Staphylococcus aureus culture filtrate. Granulocytes obtained from normal volunteers during the 48 hr following ingestion of aspirin did not respond normally to endotoxin stimulation. Furthermore, pretreatment of mice wit...
