In the previous report the author described the results of the investigations on the circulatory system and the renal functions of 32 inhabitants over 90 years of age at Kamaishi on the Sanriku Coast in Northern Japan. In this study the determinations of the serum lipids levels, the examinations of the urinary glucose, the fasting blood sugar, the hepatic functions, surveys of the nutritional conditions and ophthalmologic examinations were performed.
The mean serum cholesterol level was 186.3± 22.1mg/
dl in the males and 212.6±72.3mg/
dl in the females. The serum triglycerids level was normal in all subjects except one who showed of abnormally high level (120mg/
dl). The β-lipoprotein was normal in all subjects.
Five subjects had fasting blood sugar above 100mg/
dl. No glycosuria was, however, present in these subjects. In the urine analysis, 23 cases were negative of glucose but trace or small amount of glycosuria were detected in each two cases and moderately in one.
So the fasting blood sugar of the person swho had glycosuria were under 100mg/
dl in all that any of them was not considered as a diabetic.
In the hepatic function tests, the serum transaminases were normal in all subjects, but 34.4% showed positive in CCF test. In 57.1% of the subjects, it exceeded more than 4 units in TTT, and 15.6% was over 12 units in ZTT.
Their visual powers were under 0.3 in all, and the only 13 eyes amoung 54 eyes were found of the retinal grounds faintly. In generally, all had so progressive senile cataractas that could not analized of its degrees of the retinal arteriosclerosis.
The protein intake was 1.0∼1.5g per kg of body weight and the animal protein intake was almost qual to the vegitable origins. They had poor intake of vitamins and minerals in general, except the phosphorus, but much intake of vitamin A was observed in 100-year-old female and 113-yearold male, in compared to the total calorie the more vitamin B complex intake was noticed in these centenarians.
