Male and female virgin rats and breeder rats with naturally-occurring diabetes, hypertension and arteriosclerosis, were made severely diabetic with a single, subcutaneous injection of alloxan (10 mg/100 g b.w.), after an 18 h fast. During five months of unrelenting diabetes, some animals became obese while others became emaciated. Only the emaciated animals survived but they were blind, their adrenal glands were hemorrhagic, hypertrophied and thrombosed, thymi involuted, kidneys swollen, hearts reduced in size while testes and ovaries were atrophic. Serum CPK, SGOT and SGPT were elevated concomitant with extensive cardiovascular damage, hepatic steatosis and generalized catabolism. Circulating triglycerides and free fatty acids were markedly elevated with total cholesterol only slightly increased. BUN and serum calcium levels were also greatly elevated. Sub-normal Cmpd. B levels indicated impaired adrenal steroidogenesis. Virgin rats developed arteriosclerosis and male and female breeder rats showed exacerbation of their pre-existing aortic sclerosis as well as P.A.N. lesions in their small-sized arteries. It is believed that severe diabetes causes exacerbation of the endogenous hormonal milieu resulting from abnormal hypothalamic-pituitary-adrenal function induced by repeated breeding, which conditions the connective tissue components of the arterial wall of rats toward accelerated degenerative changes.

Sexually mature, male and female Sprague-Dawley rats were housed in large communal breeding cages or in smaller paired breeding cages. Virgin control rats of the same age were housed similarly but segregated by sex. Breeders became obese, developed a fatty liver, and showed elevated levels of triglycerides, free fatty acids, and cholesterol. Breeders had high blood pressure, enlarged hearts, hyperglycemia, and islet beta cell degranulation. Serum enzymes, creatine phosphokinase, serum glutamic oxalo-pyruvic transaminase, serum glutamic pyruvic transaminase, lactate dehydrogenase, and blood urea nitrogen levels were elevated in breeder rats. The adrenal glands of male breeders appeared hyperactive; the adrenal glands of female breeders were thrombosed and appeared to be hypoactive. Male breeder rats developed microscopic aortic lesions only; female breeders developed advanced calcific aortic sclerosis. Male breeders kept in active stud service manifested the most abnormal metabolic and pathophysiological changes. Female breeders developed similar pathophysiological changes after four pregnancies, irrespective of their paired or communal breeding environment. Virgin rats were normal regardless of housing conditions. Our findings suggest that repeated breeding in male and female rats causes resetting of the hypothalamic-pituitary-adrenal-gonadal axis. This may lead to disturbed hormonal and metabolic changes which culminate with the development of accelerated cardiovascular degenerative changes.

In order to investigate the combined effects of diabetes and hypertension on the pathogenesis of cardiovascular disease, adult male and female SHR rats which develop hypertension spontaneously were given a single, 10 mg or 15 mg/100 g body wt. injection of alloxan s.c. to induce moderate or severe diabetes. Insulin was deliberately withheld. Animals were examined by autopsy daily for 7 days post-alloxan and after 4 and 8 weeks. Mortality was high--only 52% of the males survived as against 80% of the females. Most deaths occurred on Day 5 and were associated with adrenal haemorrhage and hyperplasia, thymus galnd involution, fatty liver and marked hypotension despite elevated aldosterone levels. During the first week, corticosterone levels increased significantly in the male; in females they showed little change. After 4 weeks, the severly diabetic animals became emaciated and moribund; corticosterone and aldosterone levels fell to very low levels despite adrenal hyperplasia. The beta cells of the moderately diabetic animals eventually lost their ability to secrete insulin and these animals too became cachetic and moribund with concomitant elevation of lipid, glucose and BUN levels, as well as myocardial infarction, fatty liver, and generalized hyalin arteriolo-, arterio-, and nephrosclerosis. It is suggested that the combined hormonal and metabolic alterations of diabetes and hypertension reinforced one another in these spontaneously hypertensive rats, leading to intense stimulation of the hypothalamic-pituitary-adrenal system, the exacerbation of those cardiovascular degenerative changes known to be associated with uncontrolled diabetes or hypertension, eventual impaired adrenocortical steroidogenesis, hypotension and death.

The physical disease profiles of 135 female and 736 male inpatient alcoholics, similar in age, social class, and referral pattern, were compared to further clarify the widespread clinical impression that female alcoholics are more illness-prone. Although the women had been drinking hazardously for fewer years, at admission the prevalence of most diseases was similar in men and women. There was, however, an excess of anemia in women and of fatty liver and chronic obstructive lung disease in men. Furthermore, the average duration of hazardous drinking before the first recorded occurrence of almost all illness events was shorter in women, the sex differences being statistically significant for fatty liver, hypertension, obesity, anemia, malnutrition, gastrointestinal hemorrhage, and an ulcer requiring surgery. These findings suggest that the development of physical morbidity in relation to hazardous drinking may be accelerated in women.

The physical-disease charcteristics of 125 skid row and 736 non-skid row male alcoholics were compared in detail to determine whether skid row alcoholism is characterized by a distinct medical, as well as a social, profile. Trauma, tuberculosis, venereal disease, and malnutrition were more common in the skid row alcoholics. Epilepsy, peripheral neuritis, acute brain syndromes, chronic brain disease, and lifetime recordings of all nervous system illnesses also occurred more frequently in the skid row group, as did gastritis, gastrointestinal hemorrhage, ulcer surgery, and postgastrectomy syndrome. Fatty liver, hypertension, ischemic heart disease, cardiomyopathy, and cardiovascular illnesses of all kinds, however, were less common. The skid row medical profile is, in part, the product of a unique sociologic environment. Thus, skid row alcoholism may be viewed as a distinct sociomedical entity.

Most of the common breakfast cereals tested were unable to support growth or promote health in young rats that consumed these products as their only food. An anemia, accompanied by fatty liver and large concentrations of iron stored in the liver, was observed with cereals having the lowest protein content. Some cereals produced a marked elevation of systolic blood pressure at certain times. Low cholesterol levels were invariably associated with fatty livers, whereas high cholesterol levels seemed to be associated with hypertension at the 45-day period. When only the ready-to-eat cereals were considered, there was a positive correlation between the dietary zinc/copper ratio and the plasma cholesterol concentration.

The causes of maternal deaths in our hospital from 1981 to 1989 were analysed. There were 12,819 live births and 6 maternal deaths during this period, a maternal mortality rate of 46.69/per 100,000. The main cause of maternal deaths was acute fatty liver of pregnancy (50%), and next cardiac disease, acute hemorrhagic necrotic pancreatitis and hemorrhage of subarachnoid space (each 16.67%). There was no death due to obstetric hemorrhage, pregnancy induced hypertension syndrome or ectopic pregnancy. It is suggested that needle biopsy of the liver should be done for pregnant women with jaundice of unknown cause. Pregnant women with cardiac disease should be under the care of both obstetrician and internist in collaboration and cesarean section is indicated when the woman's cardiac function remains at grade 3 or 4.

Intraperitoneal and subcutaneous routes of administration for diabetics on CAPD were compared. The comparison included: (1) Control of blood glucose concentration: both methods can provide satisfactory glycemic control for most patients. Changing the method of insulin administration is warranted when one method fails. (2) Effect on plasma insulin levels: intraperitoneal administration can produce a plasma insulin profile similar to the normal profile. This is unusual with subcutaneous administration. Consequences of hyperinsulinemia (hyperlipidemia, hypertension) seem, however, to be similar between the two methods of insulin administration. (3) Effect on peritoneal permeability: permeability characteristics are maintained unchanged, usually, with either method after long-term CAPD. However, insulin is mitogenic in vitro. Theoretically, intraperitoneal insulin could lead to peritoneal fibrosis. (4) Effect on infectious complications of CAPD: a difference in the rate of peritonitis or overall PD catheter-related infections has not been convincingly demonstrated between the two methods of insulin administration. Exit site and tunnel infections with staphylococcus aureus may be more frequent in diabetics receiving insulin subcutaneously. (5) Effect on hepatic structure and function: subcapsular hepatic steatosis was described in diabetics receiving insulin intraperitoneally. The clinical significance of this finding remains to be demonstrated. We conclude that both methods can be applied for insulin administration in diabetics on CAPD. The intraperitoneal method should be tried first in most instances. Prospective studies comparing the two methods are needed.

Severe pregnancy-induced hypertension and markedly elevated levels of serum alkaline phosphatase developed in a 29-year-old-woman in whom one pregnancy resulted in intrauterine death. Acute fatty liver of pregnancy developed with good fetal outcome in the next pregnancy. This case suggests that pregnancy-induced hypertension and acute fatty liver of pregnancy are part of a clinical spectrum. Moreover, classic abnormalities of liver function tests need not be present in acute fatty liver of pregnancy.

1. Childhood obesity has been increasing for the last ten years in Tateyama City. Obesity in boys between the ages of 11 to 13 years was especially prominent. 2. Childhood obesity hardly improved especially in middle and morbid obesity. Eighty-five percent of light obesity in children lead to adult obesity. 3. Complications such as hypertension, serum lipid disorder and fatty liver were also observed in childhood obesity. Considering that Tateyama City is a typical Japanese country city, the above results could be representative of Japanese childhood obesity. Recent increases in childhood obesity might be due to the westernized dietary habit.
