[Electrical responses recorded from the round window of the cat cochlea].

The parameters of the cochlear round window responses to stimulation by acoustic clicks of different intensity, polarity and frequency were studied in experiments on anesthetized cats. The intensity function reflecting the dependence of the amplitude of potential change upon the level of stimulating click included two parts differing in slope. The dependence of the electric responses on the stimulus intensity and frequency was also studied. A specific form of the reaction was found in some cases. The study of all these parameters gives us some reasons to make a conclusion on the function of the auditory nerve.

[Study of alcohol binding with serum albumin by NMR spectra of frozen aqueous solutions].

Interaction of alcohols (methanol, glycerol, sorbitol) with human serum albumin (HSA) was studied by the use of NMR spectroscopy in frozen aqueous solutions. The amount of binding was shown to increase in the series methanol-glycerol-sorbitol, on this basis a suggestion is made that interaction of alcohols with HSA occurs due to the formation of hydrogen bonds in which the hydroxyl groups act as proton donors. It is found that the presence of albumin influences significantly the outcome of eutectics from a diluted methanol solution and glycerol solution, the temperature of eutectics decreases in case of methanol and increases in case of glycerol.
