Oral GBF therapy may have the potency to reduce clinical activity of UC. We believe that these results support the use of GBF administration as a new adjunct therapy for UC.

AST-120 is useful for the control of intractable anal fistulas in CD patients.

We studied 14 patients using endoscopic color Doppler ultrasonography (ECDUS) to evaluate the hemodynamics of gastric varices, and evaluated the endoscopic therapeutic effects on gastric varices in 8 patients. Three patients had F3 type gastric varices and eleven had F2. The ECDUS was performed with a PENTAX FG‐32UA (7.5MHz, convex type) and a HITACHI EUB 565 was used as a display machine. The intramural blood flow in the gastric varices and inflows from the extra‐gastric wall were clearly observed with the ECDUS in all 14 patients. The extramural blood flow (gastro or spleno‐renal shunts) was detected in 9 of 14 patients. The velocity of the intramural flow in tumorous type varices (F3) was higher than in the nodular or flat elevated type (Fa). Next, we evaluated the therapeutic effects on gastric varices of the ECDUS. The successful disappearance of intramural blood flow was observed in 6 of 8 patients who had this endoscopic therapy. In two of the 8 patients, there was not enough therapeutic effect on the intramural blood flow. The extramural blood flow, however, did not change before or after endoscopic therapy with the ECDUS. Therefore, we concluded that ECDUS is a very useful modality for the diagnosis of hemodynamics and to evaluate the therapeutic effects on gastric varices.
