[Experimental studies on the effects of alpha-tocopherol in small intestinal ischemia and reperfusion injury].

In the present study, we quantified the biochemical [thiobarbituric acid (TBA) reactants, superoxide dismutase (SOD) and vitamin E] and histologic changes in the small intestinal tissue after ischemia and/or reperfusion. Sixty-seven Wistar rats were divided into 7 groups; N group: control, A-I group: 30 min. ischemia, A-II group: 120 min.

Buerger's colour.

Cyanosis of the hands and feet in Buerger's disease is known as 'Buerger's colour'. This characteristic skin colour is produced by the subpapillary venous plexus. The reactions of the subpapillary venous plexus in patients with Buerger's disease were observed by analysing the fractional blood volume of tissue using a visible light reflective spectrophotometer.

[Clinical reevaluation of continuous intravenous infusion of 5-fluorouracil--plasma concentrations and clinical dose by continuous intravenous and 60-min infusions].

Daily and intermittent continuous intravenous infusions [by gravity drip, (IVG) or infusion pump, (IVP)] and intermittent short-time intravenous drip infusion of 5-FU were carried out on advanced cancer patients. The MTD and dose-limiting toxicity were investigated in relation to the plasma concentrations of 5-FU determined by HPLC. Responses in eleven patients receiving IVG administration daily at 8-21 mg/kg/day were NC, but those given 5-FU alone showed no adverse reactions.

[Surgical treatment in dissecting aneurysm of the infrarenal abdominal aorta--report of two cases].

In this paper, we present two cases of dissecting aneurysm in the infrarenal abdominal aorta and a review of this type of lesion. DeBakey's classification has found wide acceptance since it combines both anatomical description and a basis for management. However, there is another type of the aneurysm, omitted in this classification, which involves the infrarenal segment of the abdominal aorta, the intimal tear being distal to the renal arteries.
