Some Additional Observations on the Specificity of Cholinesterase

As an extension of previous investigations (1, 2) concerning the specificity of cholinesterase, the present study deals with the effect upon enzymatic hydrolysis of variations in the chain length of the acid component of choline esters. It is known from earlier work (3, 1) that increasing the normal chain length from 2 to 4 carbon atoms results in increased cnzymatic and decreased alkaline spli...

Additional observations on the rate of growth of Lactobacillus casei.

In the preceding paper (1) it was shown that the growth rate of Lactobacillus casei may be markedly affected by variations in the amount of asparagine present in the medium. This compound may be either stimulatory or inhibitory, depending upon the conditions existing; evidence was presented which indicates that asparagine is closely related metabolically to strepogenin. For example, strepogenin...

Nivalin (galanthamine hydrobromide), an additional decurarizing agent. Some introductory observations.

Galanthamine hydrobromide (Nivalin), an alkaloid from the bulbs of snowdrops, is widely used in Bulgaria as an antagonist to non-depolarizing muscle relaxants. The pharmacology is reviewed and experiences in the use of galanthamine in 24 patients are described. It is about one-tenth as potent as neostigmine. As changes in pulse rate and blood pressure were slight, it is rarely necessary to inje...

Additional Cases and Observations Illustrating the Origin of Tubercles

ease, unfortunately so prevalent in our climate, is to be regarded as the result of the climate alone ; or whether other and more remediable circumstances in the mode of life of those who become so affected, contribute generally and powerfully to its production ; and %dly, Whether the deposition of tubercles, so often the original cause of danger and death in scrofulous diseases, is to be regar...
