title: [Disturbed microvascular permeability in the eye caused by capsaicin microinjections into the trigeminal caudalis nucleus].
abstract: Capsaicin microinjection into the trigeminal caudalis nucleus (the central projection area of trigeminal capsaicin-sensitive nerve) increase extravasation of proteins in rat eye. The effect was inhibited by ruthenium red introduction (a capsaicin receptor antagonist) and by blocking the effector functions of capsaicin-sensitive nerve endings. It is suggested that capsaicin stimulation of central terminations of trigeminal capsaicin-sensitive afferents induce an increase in the microvascular permeability of the eye, which is mediated through the effector function of capsaicin-sensitive nerves.
