[Etiology and hemodynamics of esophago-gastric varices].

The hemodynamics of the portal area, particularly of the left gastric vein in cases of esophago-gastric varices with portal hypertension have revealed that only one-third are featuring hepatofugal collateral flow (Type I), while hepatopetal and/or to and fro flow (Type II) forms make up about two-thirds. Furthermore, regarding the supply of blood to the varices, in all cases a contribution of arterial blood inflowing through the left gastric artery to the upper part of the stomach was found. Therefore, concerning the etiology of varices other than that due to hepatofugal collaterales, a hyperdynamic state of the upper part of the stomach area has been considered as an important factor.

[Anosmia or hyposmia after long-term oral administration of tegafur--improved anosmia].

Seventeen patients who manifested anosmia or hyposmia after long-oral administration of Tegafur (FT-207) in postoperative chemotherapy for cancer were followed up. Anosmia improved in 9 of 17 patients (52.9%), and the recovery period was between 3 and 42 months after the manifestation, and between 1 and 35 months after discontinuation of FT-207.
