Angiosarcoma is the most common primary intracardiac malignancy, but many published papers have reported it to be rather rare. The prognosis of angiosarcoma is known to be very poor, and the treatment of choice has been surgery until recently, but many centers currently tend to try multimodal therapies, including chemotherapy and radiotherapy. In this report, we present a rare case in which an intracardiac angiosarcoma could have threatened the patient's life in short time by the rapid progression of the tumor, which caused right atrial rupture.

Brownish discoloration develops very rapidly in the storage of dried oyster. This undesirable browning is mainly caused by the series of reactions of sugar-amino condensation, enzymatic oxidation of tyrosine and/or the oxidative rancidity of lipids in the tissue of oyster. Sulfites are commonly used as inhibitors for Maillard type browning reactions in agricultural products. The inhibitory effect of sulfite treatment on canned oysters was also confirmed in some investigations. The results suggested that sulfites not only work on blocking the amadori rearrangement but also on the reduction of free tyrosine which retards the progress of enzymatic oxidation of tyrosine by tyrosinase. In this paper, the effect of sodium sulfite treatment on the reduction of reducing sugar and free tyrosine as a function of browning inhibition in oyster was tested and other treatment with glucose-oxidase and yeast were also applied. In preparation of samples, fresh oysters were soaked in sodium sulfite solution by various concentration for different treating times, washed in running water to remove the sulfite residue, and finally dried in the shade. In the result, the treatment of sodium sulfite was certainly effective on the reduction of both free tyrosine and reducing sugars in fresh oyster. The best results were obtained by the treatment of 0.5M sodium sulfite solution for 60 minutes each for soaking and washing. Treatment with glucose-oxidase and yeast solutions, however, did appear somewhat effective but it required so much time for a certain effect that it seemed not practically applicable.
