Abstract
To improve the surgical results of aneurysms of the transverse aortic arch, it is essential to select the optimal support technique to protect the cerebral ischemia during the aortic arch occlusion. In the four year period between 1983 and 1987, 21 consecutive patients had surgical correction of aneurysms of the transverse aortic arch at our institution. The causes of aneurysms were dissection (type A) in 16 patients and arteriosclerosis in 5 patients. Seven patients had emergency operation for frank or impending rupture. Two method for cerebral protection were employed during the period of arch exclusion. In Group I, 11 patients underwent selective cerebral perfusion both to innominate and left common carotid arteries via one roller pump at a rate of 600 ml/min (25 degrees C). The average cerebral perfusion time was 70.4 +/- 20.5 minutes. In Group II, 10 patients underwent deep hypothermia (15 degrees C to 20 degrees C) and total circulatory arrest to allow repair of the transverse aortic arch. The concomitant AVR was performed in two patients and CABG in one patient. The average cerebral arrest time was 35.2 +/- 3.4 minutes. Two out of 10 patients had additional cerebral perfusion because cerebral ischemic time exceeded over 45 minutes. There were three early deaths (14.3%) in this series. The causes of early death were bleeding in two patients and renal failure in one patient. There were no cerebral complications in both groups. The duration of extracorporeal bypass necessary for cooling and rewarming phase in Group II was longer than that in Group I.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To determine the effects of aorto-coronary bypass grafting on left ventricular diastolic function in patients with low ejection fraction (EF less than or equal to 0.40), 17 patients were studied. They were divided into two groups, Group I: 8 patients without previous myocardial infarction, Group II: 9 patients with previous myocardial infarction. Left ventricular diastolic function was assessed by maximum negative dp/dt, constant T, diastolic compliance and 1/3 functional filling. In conclusions, when ejection fraction is depressed (EF less than or equal to 0.40), myocardial revascularization improves left ventricular diastolic function in patients without previous myocardial infarction, but not with previous myocardial infarction.

Abstract
6-Amidino-2-naphthyl [4-(4,5-dihydro-1H-imidazol-2-yl) amino]benzoate dimethanesulphonate has been developed for the therapy of pancreatitis. A reversed-phase high-performance liquid chromatographic assay of the levels of this drug and its metabolites in biological fluids was investigated. Fluorescence detection with post-column alkaline degradation was used for the determination of the intact drug and the amidinonaphthol moiety metabolite, and ultraviolet detection at 254 nm was used to determine the levels of the benzoic acid moiety metabolite. Satisfactory recoveries and variabilities of the intact drug and its metabolites from biological fluids were obtained. The detection limits for the intact drug and amidinonaphthol were 0.5 ng/ml at a signal-to-noise ratio of 12 in plasma and 10 ng/ml at a signal-to-noise ratio of 32 in urine and homogenized faeces, and those of benzoic acid were 5 ng/ml at a signal-to-noise ratio of 3 in plasma and 50 ng/ml at a signal-to-noise ratio of 7 in urine and homogenized faeces.

Abstract
The purpose of this paper is to compare and define the postoperative hemodynamics, cardiac function and clinical status after the modified Fontan operation in patients with complex cardiac anomalies. Thirteen consecutive patients (6 with double-outlet right ventricle [DORV] [SLL : 4, SDL : 2], 5 with single ventricle [SV] [A-III : 3, B-III : 1, C-III : 1] and 2 with tricuspid atresia [TA] [Ib : 1, IIb : 1]) underwent the modified Fontan operation. These 13 patients ranging in age from 7 to 42 years of age (mean 18) were catheterized at 7 to 46 months (mean 8 months) postoperatively. Pressure tracings at rest demonstrated a dominant "a" wave in both the right atrium and the pulmonary artery suggesting a marked right atrial contraction after this operation. Left ventricular filling pressure was significantly decreased after the modified Fontan operation in DORV and SV. The ejection fraction and left ventricular end-diastolic volume index were unchanged or slightly increased after the modified Fontan operation. Cardiac index in 6 patients with DORV was significantly increased from rest to exercise by +48% (p less than 0.05) with a significant increase in the stroke volume (p less than 0.05) and with a slight increase in heart rate, but this index in 5 patients with SV and in 2 patients with TA was not significantly increased from rest to exercise. In the postoperative clinical status, 11 of 13 patients were in NYHA class I and 2 in class II at follow-up periods ranging from 4 to 75 months (mean 48 months). These results suggest that the modified Fontan operation can be of value and can provide excellent exercise tolerance for patients with complex cardiac lesions.

Abstract
Thirty-one patients with a ruptured sinus of Valsalva aneurysm (SVA) were operated on between January, 1961, and December, 1987. Twenty-five patients (81%) were in New York Heart Association (NYHA) Functional Class III or IV. Coexistent cardiac anomalies included a ventricular septal defect (VSD) in 16 patients (52%) and aortic valve regurgitation in 12 patients (39%). The ruptured SVA originated from the right coronary sinus in 29 patients (94%) and the noncoronary sinus in 2 patients (6%), and drained into the right ventricle in 30 patients (97%). In 6 patients treated recently, we used patches to repair the ruptured SVA and VSD through a double approach, thereby avoiding a ventriculotomy. This method resulted in no recurrent rupture or residual VSD postoperatively. There was one operative death (3%) and 4 late deaths (13%). Of the 26 surviving patients, 22 (85%) were in NYHA Class I at follow-up ranging from 6 months to 26.7 years (mean, 11.1 years). Actuarial survival at 25 years is 85.6 +/- 7.4% (mean +/- standard deviation). Repair of ruptured SVA with a patch through a double approach provides an excellent operative procedure and offers a long-term outcome.

Abstract
One-cell embryos from certain mouse strains were found incapable of developing beyond the 2-cell stage in vitro (2-cell block), but a microinjection of EDTA effectively overcame this block. When 2-cell arrested embryos were fused with embryos that had developed to the late 2-cell stage in vivo, the fusants developed beyond the 2-cell stage. Microinjection of cytoplasm of in vivo 2-cell embryos into 1-cell embryos also obviated the 2-cell block. Analyses of 35S-labeled embryos by 2-dimensional polyacrylamide gel electrophoresis indicated changes in synthetic protein patterns possibly related to this block.

Abstract
A total of 378 patients with aortic aneurysm, consisting of 128 with abdominal aortic aneurysm (AAA) and 250 with thoracic aortic aneurysm (TAA), underwent operation in our institution during the past 20 years. Of these patients, 58 with AAA and 63 with TAA were 65 years old or over. Preoperative complications tended to be observed more frequently in the aged patients than in the younger, 'non-aged' patients. The early mortalities in the aged group were 5% for elective AAA operation, 40% for emergency AAA operation, 11% for elective TAA operation and 41% for emergency TAA operation. The 5-year survival rates in the aged group were 78.3 +/- 5.8% for AAA and 63.4 +/- 4.0% for TAA, which were not significantly different from those in the non-aged group, respectively. Postoperative complications tended to occur more frequently in the aged patients than in the non-aged patients both for AAA and TAA. The present data suggest that aggressive surgical treatment for aortic aneurysm in the aged is warranted unless other serious organ failure exists.

Abstract
Aneurysmal dilatation in a venous graft following coronary artery bypass grafting (CABG) is extremely rare. Recently, we performed a resection of aneurysm and redo CABG in two patients who developed aneurysmal changes in the graft, one after 1 year and 10 months and the other after 3 years and 11 months, and obtained good results.
