Noscapine antagonizes vasoconstrictor action of bradykinin in isolated human umbilical artery
Abstract Background: It has been demonstrated that noscapine, an antitussive opioid alkaloid, could antagonize bradykinin- induced responses such as bradykinin effects in guinea-pig ileum, cough induced by bradykinin receptor agonist and angiotensin converting enzyme inhibitors, and brain damage after brain edema both in neonatal rat model and in patients with stroke. In the present study, the...

متن کاملProstacyclin (PGI2) synthesis in the vascular wall of rats with bilateral renal artery stenosis.
The ability of vessels (rings of arteries and vena cava) to synthesize prostacyclin (PGI2) "in vitro" was analyzed in the initial (6-day) and chronic (6-week) phase of two-kidney, two clip hypertension. Male Wistar CHbb THOM rats were used. Tissues were incubated for two hours in Krebs solution containing 14C-arachidonic acid as exogenous substrate. Specimens (in benzene-ethanol 4:1 vol/vol) an...
متن کاملPulmonary vasodilator activity of prostacyclin (PGI2) in the cat.
We studied the pulmonary vascular effects of prostacylin, PGI2, in the cat with intact chest under conditions of controlled blood flow. Intralobar injections of PGI2, 0.03--1 microgram, decreased arterial pressure in the perfused lobe in a dose-dependent manner. Inasmuch as lobar blood flow was held constant and left artrial pressure was unchanged, the fall in lobar arterial pressure reflects a...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
