Studies on the Protein in Cat's Perilymph and the Effect of Ultrasound On the Protein

Abstract

Perilymph samples were collected from normal cats and from cats subjected to ultrasonic irradiation and were analyzed for protein. The control values were between 144.8 mg/100 g and 211.9 mg/100 g with a confidence interval of 95 per cent. Three days after irradiation the protein concentration on the treated side had increased significantly and then, in a week, it declined and the protein values obtained from both sides were similar and greater than the control values. It seemed that both ultrasound and stress produced an increase in permeability to serum proteins and the former caused a greater increase. A few perilymph samples were collected from cases with Meniere's disease. Serum subjected to ultrasound was examined by immunoelectrophoresis. The results were discussed in terms of the effect of ultrasound in the control of Meniere's disease.
