title: Effects of cold stress and epinephrine on degranulation of peritoneal mast cells in rats.
abstract: We studied the effects of histamine liberators calcium ionophore A23187 and substance 48/80 on mast cells during cold stress and epinephrine load. Under the effect of both stress factors, ionophore A23187-induced histamine release from mast cells underwent more pronounced changes than that stimulated by substance 48/80. Cold stress and epinephrine load produce different changes in functional activity of Ca2+ channels in mast cell membranes.
