Regeneration of small intestinal mucosa after acute ischemia-reperfusion injury.

To determine whether c-Fos and c-Jun are involved in the repair of small intestinal mucosa after ischemia-reperfusion (I/R), we investigated the mechanism of regeneration following acute I/R injury in rats by evaluating changes in DNA synthesis, fractional synthesis rate (FSR) of proteins, and alkaline phosphatase (ALP) activity. Furthermore, we examined the sequential expression of c-Fos and c-Jun using western blot analysis and immunohistochemical staining. Proliferating cell nuclear antigen (PCNA) labeling index (LI) demonstrated that the LI of the I/R group at 2 and 6 hr after reperfusion was significantly higher than that of the controls.

[A trial of continuous and biweekly low-dose cisplatin and 5-FU with UFT chemotherapy for esophageal cancer].

A 77-year-old man with advanced esophageal cancer with tracheal and esophageal obstruction underwent continuous low-dose FP chemotherapy for a total of seven weeks, resulting in a complete response (CR) and disappearance of the esophago-tracheal fistula. Since discharge from the hospital, he has maintained a stable good condition for about two years while receiving biweekly low dose FP chemotherapy and oral UFT. Eight patients who had post-operative recurrence and underwent noncurative operation for esophageal cancer were given low-dose FP chemotherapy.
