Abstract
The effects of aspirin (4.0 g/day) given orally to eight patients with variant angina were observed. An exercise stress test performed in the morning was positive in two of seven patients during placebo administration, whereas a test performed in the afternoon at the same exercise work load resulted in negative findings. During aspirin administration, the afternoon exercise test repeatedly provoked anginal attacks associated with electrocardiographic changes (S-T segment elevation in five and S-T depression in two). Rate-pressure product at the end of the exercise test during aspirin administration was significantly lower than that during placebo administration (p less than 0.01). During aspirin administration, the frequency of angina increased markedly, and the attacks occurred not only during the night or early morning but also in the daytime in six of the eight patients. Our observations suggest that aspirin, in this large dose, reduces the capacity for exercise and provokes exercise-induced coronary arterial spasm in patients with variant angina.

Abstract
This report concerns a 73-year-old man complaining of intermittent, dull, umbilical pain on one month's duration. Barium-enema examination and endoscopy revealed a hemispheric cystic tumor at the midportion of the transverse colon, and the presumptive diagnosis was cystic submucosal tumor of the colon. Transendoscopic polypectomy was performed and the bulk of the lesion was locally excised from the colonic mucosa. Histologic examination revealed cavernous lymphangioma originating from the submucosa.

Abstract
A rare and instructive case of cardiac involvement by reticulum cell sarcoma in a 72-year-old woman was presented. In this case acute myocardial infarction was suspected on an electrocardiogram but was proved absent, and only scattered tumor infiltration was demonstrated at autopsy.

Abstract
Thirteen patients with Prinzmetal's variant angina performed treadmill exercise tests in the early morning and in the afternoon of the same day. The attacks with ST elevation were induced repeatedly in all 13 patients in the early morning, but in only two patients in the afternoon. Propranolol did not suppress the exercise-induced attacks in all 13 patients. Diltiazem suppressed the attacks in all 13 patients and phentolamine in eight of the nine patients. Coronary arteriograms demonstrated that spasm occluding completely or almost completely the large coronary artery supplying the area of myocardium showing ST elevation appeared during the attacks and disappeared along with the attacks after nitroglycerin administration in all four patients in whom the attacks were induced by arm exercise in the catheterization laboratory. We conclude that there is circadian variation of exercise capacity in patients with Prinzmetal's variant angina caused by coronary arterial spasm induced by exercise in the early morning but not in the afternoon.

Abstract
In four patients with exertional angina induced by arm exercise, coronary arteriograms taken before, during and after the attack demonstrated that spasm appeared in the large coronary artery supplying the area of myocardium shown to be ischemic in the electrocardiogram during the attack. The spasm disappeared with subsidence of the attack after administration of nitroglycerin. Anginal attacks induced by treadmill exercise were not suppressed by propranolol, 60 mg orally, in two of the four patients. However, such attacks were suppressed in all patients by oral administration of diltiazem (90 mg, four patients) or nifedipine (20 mg, three patients) or intramuscular injection of phentolamine (0.2 mg/kg body weight, three patients). It is concluded that coronary arterial spasm can be induced by exercise and can cause exertional angina in some patients. Diltiazem and nifedipine, calcium antagonistic drugs, prevent spasm.

Abstract
Vigorous hyperventilation was induced for five minutes immediately after a five-minute infusion of 100 ml of Tris-buffer (pH 10) in nine patients with Prinzmetal's variant angina. In eight of the patients, chest pain with ischemic changes in the electrocardiogram occurred during this procedure or within five minutes after it ended. Coronary arterial spasm appeared after the procedure and disappeared after the administration of nitroglycerin in all four patients in whom coronary cinearteriography was performed. This was evident both before and after the procedure and after sublingual administration of nitroglycerin (0.6 mg). The oral administration of 90 mg of diltiazem, a calcium antagonistic drug, two hours before, completely suppressed the attack induced by the procedure in all of the five patients who received this drug. We conclude that hyperventilation plus Tris-buffer infusion induces coronary arterial spasm and anginal attack in patients with Prinzmetal's variant angina and that diltiazem suppresses these reactions.

Abstract
To twenty six patients with angina at rest (including 13 patients with Prinzmetal's variant angina), propranolol 40--50 mg, dilitiazem 60--90 mg, dipyridamole 50 mg, atropine sulfate 0.6 mg and phenoxybenzamine 10--20 mg were given at 9:00 p.m. and 2:00 a.m. (except phenoxybenzamine which was given only at 9:00 p.m.) to examine the effect of these drugs on the attack. Propranolol was not only ineffective in suppressing the attack but rather tended to aggravate it in all the cases of Prinzmetal's variant angina. It was effective to some degree in 5 of 13 cases of angina at rest other than Prinzmetal's variant angina. Diltiazem suppressed the attack completely and dramatically in all the cases of angina at rest (including Prinzmetal's variant angina). Dipyridamole was ineffective in all the cases except one in suppressing the attack. Atropine sulfate and phenoxybenzamine suppressed the attack in 13 of 21 cases and in 6 of 12 cases respectively. Coronary arteriography was done before and after the intravenous administration of 10 mg of diltiazem in 8 patients and it was demonstrated that diltiazem dilates large coronary arteries in all these patients. It is concluded that diltiazem, a calcium antagonistic drug, is specifically effective in suppressing the attack of angina at rest by dilating large coronary arteries and that the autonomic nervous system plays a role in the genesis of the attack probably by constricting large coronary arteries by way of alpha adrenergic receptors.

Abstract
Host specific restriction was detected in 13 Bacillus strains, when 63 strains of Bacillus subtilis and 15 other Bacillus strains were tested with phage phi 105C. These 13 strains were classified into 8 groups (M,H,C,N,E,F,G,P) by the type of restriction. M-type strains (B. subtilis Marburg 168, its derivatives, and two other strains) showed relatively weak restriction, restricting phi 105C from other groups of Bacillus by ratios of 10(-1) to 10(-3). Strains of groups H,C,N,E,F,G, and P restricted phi 105C from other groups by ratios of 10(-2) to 10(-8). It was confirmed with some of the strains that type-specific modification was endowed only by the last host. Furthermore, we isolated one restriction deficient mutant of B. subtilis Marburg 168-YS11, which had also lost its modification phenotype.

Abstract
In malignant disease with severe obstructive jaundice, survival after operative intervention is extremely low. Simple external biliary drainage is desirable for these patients, as a preliminary procedure for radical operation or long-term palliation. Intrahepatic biliary drainage at the anterior edge of the liver can be performed easily and safely under local anesthesia in case of obstruction of the proximal bile ducts, just as cholecystostomy is indicated for obstruction of the common bile duct.
