JOURNAL FREE ACCESSThe electrocardiograms and vectorcardiograms of 80 cardiac patients and 51 normal subjects were quantitatively analyzed and the results were compared with the echocardiographic observations. The patient group consisted of 7 cases of hypertrophic cardiomyopathy, 19 cases of dilated cardiomyopathy, 17 cases of hypertensive heart disease and 37 cases of aortic valve disease.
The routinely measured voltage parameters such as RI+ SIII, RaVL, RaVF, SV1, RV5 and Sv1 + RV5 and the magnitude of the planar maximum QRS vector all correlated positively with the left ventricular mass index, left ventricular wall thickness, interventricular septal thickness, posterior wall thickness and left ventricular diastolic dimension index. However, the measured voltages correlated much better with the indices of left ventricular mass and wall thickness than with left ventricular diastolic dimension. Thus, the enlarged QRS vectors in left ventricular hypertrophy were considered to be mainly the result of the increase in left ventricular muscular mass rather than left ventricular cavitary dilatation. On the other hand, calculation of the diagnostic sensitivity and specificity for each voltage parameter revealed that all of the above measurements were diagnostically almost equivalent : none was superior to the others. There fore, some parameters other than the QRS voltage should be included to set better criteria for the diagnosis of left ventricular hypertrophy.View full abstractDownload PDF (1141K) -

JOURNAL FREE ACCESSBlood pressure, pulse rate, plasma catecholamine and plasma renin activity in response to standing and mental stress were studied in 28 normotensive subjects, 14 borderline hypertensive patients (BHT group) and 14 patients with essential hypertension (EHT group). The normotensive subjects were further divided into 2 groups : 14 subjects with normotensive parents (PNT group) and 14 with hypertensive parent (s) (PHT group).
Mean basal norepinephrine of the BHT and EHT groups was significantly higher than that of the PNT group. The increases in blood pressure, pulse rate and plasma norepinephrine in response to standing and mental stress were lower in the EHT group than in the other three groups. The increase in plasma epinephrine in response to mental stress was higher in the PHT and BHT groups than in the PNT and EHT groups.
A higher incidence of high blood pressure in response [≥ 20mmHg in systolic blood pressure] (higher responders) to mental stress was found in the PHT, BHT and EHT groups compared with the PNT group. The increases in plasma epinephrine of the higher responders to mental stress in all groups were higher than in the lower responders [≤19mmHg in systolic blood pressure to mental stress], and basal plasma epinephrine in the higher responders was higher than in the lower responders.
The results indicate that the genetic predisposition to hypertension plays a significant role in determining plasma catecholamine levels and the responsiveness to stress, especially to mental stress.View full abstractDownload PDF (1292K) -

JOURNAL FREE ACCESSThis report consists of retrospective analysis of operability in 16 patients with gallbladder cancer, who were diagnosed radiologically. All cases were operated and pathological studies were performed.
1) Eighty-one percent of gallbladder cancer was diagnosed correctly on US. We classified ultrasonographic pictures of gallbladder cancer into four types. Two cases of fungating mass type underwent complete resection.
2) Eighty-five percent of gallbladder cancer was diagnosed correctly on CT. However, there was no statistically significant difference in diagnosing operability between CT and US.
3) Ninety-three percent of gallbladder cancer was diagnosed correctly on AG. When the cystic artery showed abnormalities such as encasement or irregularity, 50% of cases underwent resection. Among patients with abnormalities of the intrahepatic vessels, none was resectable.View full abstractDownload PDF (2050K) -

JOURNAL FREE ACCESSA total of 198 patients who underwent surgery for colorectal cancer in our department between 1966 and 1985, and 187 of those with single cancer were investigated mainly for the rate of resection and the late results. The rate of resection for cancer of the colon was higher than that for ano-rectal cancer, but there was no difference in the rate of curative resection between them. The incidence of lymph node metastasis was about 40% in both groups treated by curative resection, but the incidence was high, more than 90%, in the group treated by non-curative resection. Five-year survival rate in patients with cancer of the colon treated by curative resection and in those treated by non-curative resection were 68% and 11%, respectively. Five-year survival rate for patient with ano-rectal cancer treated by curative resection and by non-curative resection were poor, namely 53% and 9%, respectively. There were significant differences in histological stage between stage I and stage III of ano-rectal cancer and between stage I and stage IV of these patients, suggesting favorable prognosis for stage I.View full abstractDownload PDF (736K) -

JOURNAL FREE ACCESSIn this study, the course of dilated coronary arterial lesions in Kawasaki disease was followed by evaluating selective coronary arteriography performed twice in 39 cases, initially 6 months after the onset of disease and subsequently 2 years and 6 months later.
Follow-up study revealed that mildly dilated coronary arteries (less than 6 mm in diameter) regressed to normal in 60 to 70% of cases, moderate cases (dilation from 6 to 10 mm in diameter) regressed to normal in 30 to 40%, but severe cases (dilation greater than 10 mm in diameter) did not show regression. Thus, the severity of coronary lesions may be estimated by the size of coronary artery dilation for predicting the prognosis of patients with Kawasaki disease. Namely, giant coronary lesions usually change into obstructive coronary lesions and are associated with impaired left ventricular function resulting from myocardial ischemia.
It is of clinical importance is to prevent or reduce the progression of coronary arterial diseases, and even if coronary aneurysms occur, every effort should be made to preclude the advanced shift to obstructive coronary lesions.View full abstractDownload PDF (1661K)
