The Configurational Relationship of Dextro-methylethyl Carbinol to Dextro-lactic Acid.

Configurational Relationships of Methylethyl

The configurational relationship of dextro-methylethyl carbinol to dextro-lactic acid has been established.’ The establishment of the relationship of the higher members of the homologous series of alcohols to the same reference substance will permit the correlation of the configurations of the alcohols among themselves. The present paper contains a report on the results of the efforts in this d...

Antianalgesia: stereoselective action of dextro-morphine over levo-morphine on glia in the mouse spinal cord.

We have previously shown that the naturally occurring levo-morphine at a subanalgesic picomolar dose pretreated i.t. induces antianalgesia against levo-morphine-produced antinociception. We now report that the synthetic stereo-enantiomer dextro-morphine, even at an extremely low femtomolar dose, induces antianalgesia against levo-morphine-produced antinociception using the tail-flick (TF) test ...

Dextro Propoxyphene and the Ventilatory Response to Carbon Dioxide in Man †

Dextro propoxyphene (Darvon®) is an orally effective analgesic said to be equipotent on a weight basis with codeine both in experimental animals and in man.' When administered parenterally in 50 mg. doses it has also been reported3 to produce analgesia equivalent to that observed following 50 mg. of meperidine. Codeine and meperidine as well as other narcotics are recognized respiratory depress...

Echocardiography of the Intra - atrial Baffle in Dextro - transposition of the Great Vessels By NAVIN

Twelve patients with dextro-transposition of the great vessels (age eight months to four years) were studied by echocardiography following Mustard's procedure. Nine of them had also been studied preoperatively. Postoperatively all patients demonstrated structural echoes in the atrial cavity behind the pulmonary root. In ten, the motion pattern generally resembled that of a stenotic atrioventric...
