Stimulation of brain periventricular and hypothalamic substance P receptors induces a pressor response and tachycardia associated with mesenteric and renal vasoconstriction and hindlimb vasodilation resembling thus the classical defense reaction. This cardiovascular response is brought about by the activation of the sympathoadrenal system and is accompanied(More)
In vitro, macrophages from normal strain BRVR mice killed Salmonella more quickly than did macrophages from normal strain BSVS mice. Salmonella injected intraperitoneally multiplied more quickly in BSVS mice than in BRVR mice. BRVR macrophages injected intraperitoneally into BSVS mice protected against Salmonella multiplication better than did BSVS(More)
