Histamine and H1 -histamine receptors faster venous circulation.

Galajda Z, Balla J, Szentmiklosi AJ, Biro T, Czifra G, Dobrosi N, Cseppento A, Patonay L, Roszer T, Balla G, Popescu LM, Lekli I, Tosaki A - J. Cell. Mol. Med. (2011)

Bottom Line: Voltage-dependent calcium channels mediated mainly the histamine-induced force generation of saphenous vein, whereas it did not act in the inferior vena cava.Importantly, transient clamping of the femoral vein in animals caused a short-term constriction, which was inhibited by H(1) -histamine receptor antagonist in vivo.Furthermore, a significantly greater histamine immunopositivity was detected in veins after stretching compared to the resting state.

Histamine-induced contraction in isolated rabbit vessels. Abdominal part (open circle) of inferior vena cava (n = 10), common iliac vein (full circle) (n = 5), intrathoracic part (open square) of inferior vena cava (n = 7). The histamine-induced increases in tension are normalized for vessel cross-sectional area, and absolute values of the increase in tension are shown. Data represent mean ± S.E.M.
