Sterilizing Action of Acids. VIIIth Report

Chronic Recording of Regenerating VIIIth Nerve Axons

Self-sterilizing inoculating loop.

A self-sterilizing inoculating loop consisting of a step-down transformer and an adjustable timing circuit are described.

Propylene oxide as sterilizing agent.

Liquid propylene oxide added to a variety of disinfectant solutions resulted in a significant reduction of the bacterial spore content of these solutions.

The Hemolytic Action of Inorganic Acids

In his monograph “The Erythrocyte and the Action of Simple Hemolysins,” Ponder (1) states that very little satisfactory work has been done on the hemolytic action of acids and alkalies. Reference to Jacobs’ review in Cowdry’s “General Cytology” (2) and to Hober’s and Bayliss’ discussions of hemolysis and the permeability of the red blood cell (3, 4), as well as to the work on hemolysis by Stewa...

The Disinfectant Action of Certain Organic Acids.*

The disinfectant value of strongly dissociated mineral acids, such as hydrochloric and sulphuric, depends chiefly upon the number of free hydrogen ions present. The weak organic acids, however, exert a more toxic effect than would be indicated from their degree of dissociation. Kahlenberg and True (1) found that the toxic action of the highly dissociated acids for the plant Lwpinus albus was du...
