We reviewed hearing recovery in 3,430 patients with sudden deafness reported between 1989 and 1998 in Japan, evaluated using standards of the Research Group on Sudden Deafness of the Ministry of Health and Welfare of Japan. Complete recovery was seen

The effects of NaCl crystals placed on the round window membrane in the cochlea were studied by observing changes in cochlear microphonic potential (CM) at the first and the third turn of the cochlea of guinea pigs by means of a differential electrod

The magnitudes of the endocochlear dc potential (EP) during adequate ventilation and during five minutes of anoxia were recorded in control guinea pigs and guinea pigs administered various dosages of kanamycin sulfate. The magnitudes of the EP after

The electrophysiologic and histopathologic changes in the inner ear caused by the administration of cis-diamminedichloroplatinum (CP) were studied in guinea pigs. The endocochlear dc potential (EP) gradually decreased after the intravenous injection

The effects of loop diuretics on the endocochlear direct current (DC) potential and the effective electrical resistance of the cochlear partition were studied. The effective electrical resistance was increased, and the endocohlear DC potential was de

• Chloramphenicol is not ototoxic if administered for systemic effect, but topical applications of it to the middle ear produce severe cochlear toxic effects. Ethacrynic acid potentiates the ototoxicity of aminoglycosides. Guinea pigs were administ

Since the mechanoelectrical hypothesis on the production of cochlear microphonics (CM) was adovocated by Davis in 1958 and 1968, it has been agreed that the DC potential gradient of 160mV which consists of endocochlear DC potential (EP) and negative

To study the rationale of the glycerol test, cochlear potentials were measured in albino guinea pigs after intravenous administration of 50% glycerol solution. The endocochlear dc potential was reduced slightly within a few minutes after glycerol inj

The endocochlear dc potential was recorded in normal and Kanamycin pretreated guinea pigs after Nitromin administration. In Kanamycin pretreated guinea pigs, whose Pryer reflex had already disappeared, endocochlear dc potential did not decrease at al
