A case of congenital hepatic fibrosis: usefulness of hepatobiliary scintigraphy.

A case of operatively proven congenital hepatic fibrosis was studied by scintigraphy with Tc-99m-phytate and Tc-99m-Pl (a hepatobiliary radiopharmaceutical). Two focal defects were recognized in the liver on the colloid liver scintigram. Ultrasound and contrast angiography suggested that the two focal defects were cystic lesions. Radionuclide hepatobiliary imaging was performed with Tc-99m-Pl, since intravenous cholangiography was unsatisfactory. One focal defect was proved to be a dilated intrahepatic bile duct and another was found to be cyst. Radionuclide hepatobiliary imaging with Tc-99m-Pl proved to be very useful in identifying dilated intrahepatic bile ducts in this patient as well as in following the progress of this disease.

Changes in electroencephalogram of the rat following olfactory bulbectomy.

The changes in electrical activities following olfactory bulbectomy were investigated in rats with chronically implanted electrodes, in comparison with those induced by septal lesions. Electroencephalogram (EEG) of the amygdala changed to low voltage fast waves immediately after bilateral olfactory bulbectomy, while EEG of the neocortex gradually showed an arousal pattern consisted of low voltage fast waves, and hippocampal theta waves were markedly synchronized during the period of a week or so after bulbectomy accompanied with the appearance of characteristic hyperemotionality. No change was observed in EEG of the septum, hypothalamus or the midbrain reticular formation. Following unilateral olfactory bulbectomy, no behavioral changes occurred, but EEG of the ipsilateral amygdala showed low voltage fast activity without causing any EEG changes in other brain structures. Bilateral septal lesions immediately caused hyperreactivity in rats which gradually disappeared during the course of a week or two after the surgery. The hippocampal theta activity completely disappeared and EEG turned to low voltage fast waves immediately after septal lesions, but no significant EEG change was observed in the amygdala or the neocortex. This change in hippocampal EEG continued for a long time even after hyperreactivity disappeared.

Effect of phalloidin on platelet aggregation.

By the addition of phalloidin, an oligopeptide of Amanita phalloides, to platelet-rich plasma, an increase of its transparency could be observed. The rate of increase of transparency was slow but the maximal intensity corresponded to that of ADP aggregation. Morphologically, many microfilaments were formed in the cytoplasm. But the figures were different from those in platelets in ADP aggregation.
