Cardiovascular and respiratory effects of dermorphin in rats.

The cardiovascular and respiratory effects of dermorphin (D) have been evaluated in freely moving or anesthetized normotensive and spontaneously hypertensive male rats. Intravenously or intracerebroventricularly administration of D produced arterial hypotension with sinus bradycardia and respiratory depression. Naloxone antagonized the effects of D.

Influence of rat prenatal and postnatal exposure to a non-steroidal anti-inflammatory agent (flunoxaprofen) on cardiovascular function in the progeny.

The present experiments evaluated in rats the effects of prenatal and postnatal exposure to a non-steroidal antiinflammatory agent, flunoxaprofen (5-10 and 20 mg/kg/day by the oral route), on cardiovascular function in the pups. In both conscious and anaesthetized rats pre- and postnatal flunoxaprofen exposure at the 30th and 60th day of age, significantly (P less than .05) induced a decrease of pressor response to carotid-sinus baroreceptor stimulation and to L-noradrenaline (0.

Pharmacodynamic profile of fenoverine, a novel modulator of smooth muscle motility.

Experimental research has documented that fenoverine is a depressant drug mostly active on the intestinal smooth muscle; however, it is also active on other tissues as well as on the genito-urinary tract. Fenoverine may be considered a synchronizer of smooth muscle effective in modulating the intracellular influx of calcium into the cell and its release from the intracellular pool. Fenoverine causes a reduction of the excitatory junction potential (EJP) in intestinal smooth muscle by stimulating parasympathetic efferent fibres without any change in the inhibitory junction potential (IJP).
