Correlation between cancer mortality and alcoholic beverage in Japan.

Geographical correlations between standardized, mortality ratios (SMRs) of cancers and consumption of different types of alcoholic beverages (saké synthetic saké, shochu, beer, wine, and whisky), of cigarettes, and urbanization were examined for all 46 prefectures in Japan. Suggestive correlations were observed between cancer of the oesophagus in males and both shochu and whisky (r = 0.27 and 0.22 respectively), between cancer of the rectum in males and wine (r = 0.45), and between cancer of the prostate and shochu (r = 0.50). These correlations were also confirmed in the partial correlations between SMRs of cancers and consumption of alcoholic beverages, controlling for the two variables urbanization and consumption of cigarettes. Alhtough cancers of other sites were also correlated with certain types of alcoholic beverages, their associations seemed to be secondary to other factors. The validity of higher-order partial correlations and the problems of correlation study are also referred to.

Changes in hormonal activities relative to the severity of essential hypertension.

Endocrine activity in patients with essential hypertension was studied by measuring the urinary excretion of catecholamines, prostaglandin E (PGE) and cyclic adenosine monophosphate (cAMP). Simultaneously, plasma renin activity, concentrations of serum sodium, potassium, blood urea nitrogen (BUN) and creatinine were determined. Systolic blood pressure and BUN increased progressively with age until the sixth decade. Urinary excretion of norepinephrine was correlated with the systolic blood pressure. In contrast, plasma renin activity and urinary excretion of PGE decreased progressively with the increase in systolic blood pressure. Although the cause of essential hypertension is not known, it is suggested that hypertension accelerates the aging process in the kidney and thus decreases renal PGE synthesis. This decrease of PGE in turn causes a reduction of plasma renin activity, possibly either by accelerating the retention of sodium and water or by failing to stimulate renin synthesis. A decrease of PGE may also potentiate the vasopressor action of norepinephrine.

Relative binding of testosterone and estradiol to testosterone-estradiol-binding globulin.

The binding of estradiol (E2) and testosterone (T) to testosterone-estradiol-binding globulin (TeBG) was studied in vivo at 37 C by three independent methods: equilibrium dialysis, steady state polyacrylamide gel electrophoresis, and TeBG-ligand dissociation kinetics. Equilibrium dialysis was performed at 37 C with the dialysate containing human serum albumin in amounts equivalent to that of the plasma dialysand. Scatchard analysis indicated that under these conditions E2 does not measurably bind to TeBG, while T has a Kd of 3.7 X 10(-10) M. Similarly, Scatchard-type analysis of E2 binding to TeBG in steady state polyacryalmide gel electrophoresis at 37 C revealed no high affinity saturable binding, while dihydrotestosterone was bound with a Kd of 2.7 X 10(-10) M. Examination of the dissociation kinetics of T and E2 ffrom TeBG revealed that the mean (+/-SD) T1/2 of dissociation of T from plasma at 37 C (10.8 +/- 2.4 min) was significantly shortened to 3.5 +/- 0.4 min by saturation of plasma with dihydrotestosterone (P less than 0.01), whereas that of E2 (8.9 +/- 1.4 min) was not changed (9.6 +/- 3.0 min). These data suggest that TeBG is not an important binder of plasma E2 at physiological temperatures and explain the observation that in diseases characterized by high TeBG levels, such as hyperthyroidism and liver disease, the MCR and free E2 levels have generally been normal.

Utilization of records of the National Health Insurance programs for study on cancer morbidity and survival.

Potential value of the records of National Health Insurance programs for study on cancer morbidity was investigated by examination of those preserved in two towns in Japan. By using such records, population at risk and incidence of cancer can be readily and precisely determined. Deaths with load of cancer and survival rate of cancer were also determined without difficulty. In spite of a few limitations involved in the use of records, they are considered to be highly valuable for study on cancer morbidity and survival, mainly due to absence of under-reporting and to the feasibility of obtaining medical and other informations pertaining to cancer patients throughout the specific period.

[A clinical study of PC-904 in pediatrics (author's transl)].

A clinical study of PC-904 was performed in children. The results were as follows; 1) Serum levels of PC-904 after single administration of 20 mg/kg were studied in patients by one-shot intravenous injection or drip infusion for 1 hour or 2 hours. The results obtained in this fundamental study led to the suggestion that the proper dosage in bacterial infections would be 50 approximately 100 mg/kg intravenously in 3 approximately 4 divided doses daily. 2) A clinical study of PC-904 was performed in 16 patients including acute pharyngitis and bronchitis (3 cases), acute bronchopneumonia (3 cases), pertussis pneumonia (1 case), lymphadenitis purulenta (2 cases), acute bronchopneumonia (3 cases), pertussis pneumonia (1 case), lymphadenitis purulenta (2 cases), abscess with chronic granuloma (2 cases) and urinary tract infection (5 cases). About 50 approximately 100 mg/kg of PC-904 were administered in 3 approximately 4 divided doses daily by one-shot intravenous injection. The clinical effects of 2 cases out of 16 were impossible to be evaluated, and thses cases were excluded from the clinical evaluation. Ten cases out of 14 showed excellent or good responses (efficacy rate: 71.4%). 3) The bacteriological examinations were performed and the causative or isolated organisms were determined in 11 cases. The responses were "disappeared" in 6 cases, "decreased" in 2 cases and "not disappeared" in 3 cases. 4) No side effects were observed. Abnormalities of laboratory findings were not also noticed.

[Studies of binding of testosterone-estradiol binding globulin for estradiol-17beta (author's transl)].

A fundamental study of testosterone-estradiol binding globulin (TeBG) activity for estradiol-17beta was investigated by equilibrium dialysis. In addition, the interaction of TeBG activity for estradiol and estradiol metabolism during a menstrual cycle and in hyperthyroidism was attempted to elucidate. Estradiol in plasma and 24 hrs urine was measured by radioimmunoassay. TeBG binding capacity (TBC) was measured by ammonium sulfate method and associate constant (Ka) of TeBG for estradiol was estimated by equilibrium dialysis. 1. In several pooled plasmas, the mean Ka of TeBG for estradoil was 1.25 X 10(8) L/M at 4 degrees C and 0.78 X 10(8) L/M at room temperature. The Ka decreased with increasing temperature and could not be determined with a sufficient accuracy at 37 degrees C. The mean TBC was 4.4 X 10(-8) M/L. 2. TBC and Ka of TeBG for estradiol during the normal menstrual cycle of a woman were fairly unchanged. The unconjugated estradiol value in urine showed the same biphasic pattern with a midcycle peak as that of the unconjugated estradiol value in urine. 3. A normal man was induced hyperthyroidism with a administration of triiodothyronine. The treatment of triiodothyronine caused a remarkable increase of TBC, but no changes of Ka of TeBG for estradiol and unconjugated estradiol values in plasma and urine. From these results it was suggested that the rate of metabolism of estradiol increased in hyperthyroidism.
