Combined liver-spleen-kidney scintigraphy and subsequent subtraction of the kidney scintiphotograph in the evaluation of displaced kidney.

The displacement of kidney was studied by using the combined liver-spleen-kidney scintigraphy and the subsequent subtraction of the kidney scintiphotograph to leave the liver-spleen scintiphotograph alone. A suprarenal mass was shown as cold spot between the liver and right kidney on the combined study. When the liver scintiphotograph and kidney scintiphotograph were over-lapped and the differential diagnosis was difficult, the subsequent subtraction of the kidney scintiphotograph was useful in the diagnosis of the enlarged liver.

Effect of 4 kHz tone exposure on the guinea pig inner ear: relation in the change of cochlear microphonics, action potential, electrochemical potential and K+ ion concentration induced by noise exposure.

Using 110 male albino guinea pigs, and applying electrophysiological methods, we investigated the effects of 4 kHz tone at moderate sound pressure level on the inner ear at different exposure times (6, 12, 24 and 48 h). Longer than 12 h exposure to 4 kHz tone had a considerable effect on the hearing, inducing a decrease in the maximum output voltage of cochlear microphonics and an increase in the K+ concentration in the endolymph.
