Phenylephrine interaction with specific red cell receptors.

An investigation of the action of phenylephrine on the transport of sodium across the human cell membrane is reported. The characteristic parameters of drug-receptor interaction -- the maximal response and ED50 -- were calculated based on the conventional dose-response plot and its linear transformations. The results obtained were in good agreement with other experimental findings.

[Fuctional-metabolic disorders in typhoid infection]. / Tulburari fuctional-metabolice in infectia tifica

The complex biologic investigation of thyphoid fever is dictated by the necessity of instituting a pathogenetic therapy, especially in the toxic and complex forms. Performing 178 fuctional-metabolic tests in 50 cases of typhoid fever (of which 10 severe and complicated forms), the authors established the prognostic value energy deficiency (approximately P), lactate, alkaline reserve and GPT. Azotemia is only characteristic in the forms with renal involvement, and the other transaminases may be positive even whe the liver is not enlarged. In one case of repeated digestive hemorrhage no evidence could be found of the mechanism of consumption coagulopathy.

[Possibilities of correcting some metabolic disorders in experimental endotoxic shock by treatment with a combination of alpha-lipoic acid and epsilon aminocaproic acid]. / Posibilitati de corectare a unor tulburari metabolice din socul endotoxic experimental prin asociatia acid alpha-lipoic--acid epsilon-aminocaproic

Alpha-Lipoic acid associated with xi-aminocaproic acid proves to have a protector effect in the posttreatment of endotoxinic shock in rabbits, produced by the administration of E. coli O111, in doses of 1.5 mg/kg body weight. This effect was observed when administered early in the stage of energy privation, and was manifested by a longer survival, diminution of lactacidemia and protection of labile phosphate reserves.
