[Hypocholesterolemic effect of catechol estrogen 2-monomethyl ether].

The hypocholesterolemic effect of 2-methoxyestrone (2-MeOE1), 2-methoxyestriol (2-MeOE3) and estradiol-17 beta (E2-17 beta) was investigated in two experimental systems of normocholesterolemic and dietary hypercholesterolemic rats that had undergone oophorectomy. Each compound was subcutaneously administered for 6 consecutive days at a dose of 10 micrograms per day in the former systems and at 300 micrograms per day in the latter system, respectively. The hypocholesterolemic effect was in the following relation: 2-MeOE3 = E2 - 17 beta greater than 2-MeOE1. In the latter system, the serum total cholesterol level of individual rats in both 2-MeOE3- and E2-17 beta-administered groups returned to normal. No uterotrophic activity was exhibited by either 2-MeOE1 or 2-MeOE3, while E2-17 beta exhibited an anomalous activity. The effect of 2-MeOE1 and 2-MeOE3 on body weight was not exhibited, while E2-17 beta reduced it slightly. The results suggest that catechol estrogen 2-monomethyl ether plays an important role in lipid metabolism through estrogen receptor independent mechanisms and has a pharmacologically important effect on hyperlipidemia and atherosclerosis.

Immunological abnormalities in a patient with lysinuric protein intolerance.

We report an 8-year-old girl with lysinuric protein intolerance and immunological abnormalities including impaired function of lymphocytes, the presence of LE cells, antinuclear antibodies, and hypergammaglobulinaemia. These abnormalities have not been reported before and may be due to an amino acid imbalance or protein malnutrition in cells or tissues. The coincidence of a pre-stage of systemic lupus erythematosus (SLE) and LPI is not excluded.

Cause-specific mortality among Koreans, Chinese and Americans in Japan, 1973-1982.

Mortalities from selected causes from 1973 to 1982 among Koreans, Chinese, and Americans residing in Japan were compared with those of Japanese. In the Korean population, besides the well-documented excess in mortalities from liver cancer, lung cancer, liver cirrhosis and male tuberculosis, a rather prominent elevation was observed for mortalities from female tuberculosis and diabetes mellitus in both sexes. Distinctive features in the Chinese population were increased mortalities from liver cancer and female lung cancer and lowered mortality from stomach cancer, and these findings are consistent with the observations among Chinese in other areas. Mortalities from diabetes mellitus and liver cirrhosis was moderately increased in this population as well. Americans in Japan by and large showed a mortality pattern similar to that in the US although mortality from stroke among female Americans was rather elevated during the period 1973-1977. Epidemiological studies on Koreans and Chinese in Japan with reference to their lifestyle are strongly required.

Signet ring cell carcinoma in a polyp of the colon. A case report of a six-year-old boy.

Undifferentiated adenocarcinoma of the colon occurring in a 6-year-old boy was presented. The tumor characterized by the signet ring cell appearance developed in a polyp of the descending colon. The signet ring cell carcinoma is in general a rare morphologic form of colonic carcinoma. According to our review of the literature there have been described 16 patients under 10 years of age with colonic or rectal carcinoma, disclosing 2 cases of undifferentiated or signet ring cell carcinoma including the present case. In children, mucin producing adenocarcinoma is the most predominant type of colonic carcinoma, and 48% of the colonic carcinomas are of signet ring cell carcinoma in children under 17 years of age.

Cigarette smoking, alcohol and cancer mortality: a cohort study of male Japanese physicians.

Mortalities from selected sites of cancer among 5,130 male Japanese physicians followed up for 19 years were examined in relation to smoking and drinking habits surveyed in 1965. With smoking habit classified into three categories (never/past, 1-19 and greater than or equal to 20 cigarettes/day) and drinking habit into four (never/past, occasional, less than 2 and greater than or equal to 2 go of sake/day), the effects of the two factors and their combined effect were analyzed by using the Cox proportional hazard model. Interaction of smoking and drinking was found to be negligible for the sites of cancer studied (upper aerodigestive tract, esophagus, stomach, large bowel, liver and lung), and independent relationships of smoking and drinking with upper aerodigestive cancer were confirmed. Smoking, besides being strongly associated with lung cancer, was also weakly, but significantly, related to stomach cancer. Liver cancer showed no association with smoking whereas this cancer was significantly related to alcohol consumption. The present findings provide further evidence for the association between cigarette smoking and stomach cancer but do not support the relationship recently suggested between smoking and liver cancer.

Alcohol and mortality: a cohort study of male Japanese physicians.

The relationship between drinking habit surveyed in 1965 and cause-specific mortality over 19 years was investigated in 5135 male Japanese physicians taking into account smoking habit and separating ex-drinker from non-drinker. As compared with non-drinkers, daily drinkers with high consumption had a significantly increased mortality from all causes. Drinking was significantly related to the so-called alcohol-related causes of death; upper aerodigestive cancer, liver cancer and liver cirrhosis. Mortality from acute myocardial infarction was inversely related to drinking, whereas other coronary heart disease showed a somewhat higher mortality among men consuming a large amount of alcohol than among non-drinkers. There was a weak, but significant, association between stroke and drinking, and the relation did not differ between haemorrhagic stroke and other stroke. No obvious relationship with drinking was observed for cancers of the stomach, large bowel, pancreas and lung.

[Age, parity, and time in fertility].

The authors analyze fertility trends in Japan from 1935 to 1969 using "vital statistics data upon which age-parity adjusted net reproduction tables were constructed for 35 different female birth cohorts." These tables are used to calculate "cohort net reproduction rate and total fertility rate by parity and age, [as well as] mean age at first birth, second birth, etc. and average length of birth interval in each cohort."

Cancer mortality among patients undergoing cholecystectomy for benign biliary diseases.

Potential risks of gastrointestinal cancers after cholecystectomy were examined among 1238 patients who had had their gallbladders extirpated for benign biliary diseases from 1951 to 1970. The observed deaths between 1953 and 1984 were compared with the expected values which were calculated from death rates in Japan. No appreciable excess mortality was found for stomach cancer, colorectal cancer or pancreas cancer in relation to cholecystectomy. Observed and expected deaths during the whole observation period were 29 vs. 31.58 for stomach cancer, 8 vs. 6.50 for colorectal cancer overall, 5 vs. 3.19 for colon cancer and 3 vs. 3.51 for pancreas cancer. The corresponding figures in the 10 years or more after cholecystectomy were 14 vs. 19.06 for stomach cancer, 5 vs. 4.66 for colorectal cancer and 3 vs. 2.38 for colon cancer. A notably increased mortality from liver cancer was observed, but it was considered to be related not to cholecystectomy itself but to blood transfusion.
