Serial scintigraphy of choledochal cysts using 131I-rose bengal and 131I-bromsulphalein.

Nine cases of congenital choledochal cysts are reported which were correctly diagnosed by 131I-rose bengal or 131I-bromsulphalein (BSP) serial scintigraphy. They were classified by scintigraphic patterns into two types depending on whether biliary obstruction was complete or incomplete. All but two showed incomplete obstruction. The correct diagnosis may be difficult to make by scintigraphy if complete biliary obstruction is present. In such cases the clinical findings and other diagnostic studies, such as angiography or ultrasound, should be carefully considered. Serial scintigraphy with 131I-rose bengal or 131I-BSP is nontraumatic, safe, and provides increased diagnostic accuracy. It is the examination of choice when choledochal cysts are suspected clinically.

Sensitivity to chlorpromazine effects on brain function of schizophrenics and normals. A preliminary report.

For the purpose of quantitative demonstration of the sensitivity to chlorpromazine (CPZ) effects on brain functions of schizophrenics and normal subjects, polygraphic recordings of electroencephalogram (EEG) and electrodermal response (EDR) were performed before and 3 h after oral administration of 25 mg of CPZ: percent time waking EEG (per cent W-EEG) and number per minute of EDR were measured during the resting period and the period of calculation. In 10 normal adult subject, both per cent W-EEG and number of EDR showed remarkable decrease after CPZ administration. In 22 schizophrenics, however, per cent W-EEG showed no significant decrease after CPZ administration. Number of EDR in schizophrenics during the period of calculation did not show any significant decrease. The neural mechanism underlying the lower sensitivity to CPZ effects in schizophrenics was discussed.

Scintigraphic detection of hepatic metastases with 131I-labeled steroid in recurrent adrenal carcinoma: case report.

Abdominal scintigraphy using a new 131I-labeled steroid agent was performed on a 40-year-old women proven by surgery to have adrenocortical carcinoma. Considerable accumulations were observed at the sites of liver metastasis. Hepatic scintigraphy and autopsy findings revealed that the accumulation was more marked on the active cancer cells and only slight in the central necrotic tissue. Adrenal scintigraphy is valuable in the study of metastatic hormone-producing adrenal carcinoma.
