[Changes of the plasma levels of tissue plasminogen activator and plasminogen activator inhibitor-1 in cerebral infarction induced by the venous occlusion].

To examine the fibrinolytic system and platelet factors (PF4 and beta-TG), we conducted a venous occlusion test (V.O. test) on two groups of elderly patients suffering from cerebral infarction, one group being able to walk (A group), the other being bed-ridden for during a long period (B group). Their levels of t-PA, PAI-1 antigen and platelet factors were compared between A or B, A + B and healthy elderly groups. The t-PA antigen level of both group A and B after the V.O. test tended to increase. The t-PA values of A + B groups after the V.O. test were also similar to that of the healthy elderly. The PAI-1 antigen level of both group A and B before the V.O. test was higher than that of the healthy elderly. However, the PAI-1 antigen level of both group A and B tended to decrease after the V.O. test. No remarkable changes were noted in PF4 and beta-TG, which have been thought to reflect platelet function. The above findings suggest that the fibrinolytic activity in A or B groups can recover through stimulation by exercise training and some medical treatment.

Effects of azoxymethane on X-ray induced intestinal metaplasia in Donryu rats.

The present study was undertaken to determine the effect of azoxymethane (AOM) administration on intestinal metaplasia induced by X-irradiation in male Donryu rats. Five-week-old animals were X-irradiated with two doses of 10 Gy each at a 3-day interval or three X-ray doses of 10 Gy at a 2-day interval and then received AOM injections i.m. at a dose of 15 mg/kg body weight once weekly for 3 weeks, 6 months after irradiation. Alkaline phosphatase positive foci were decreased after AOM treatments, but aberrant crypt like-foci appeared within areas of intestinal metaplasia. In contrast no induction was observed in normal-appearing gastric mucosa.
