Through the method of the "questionnaire" quantitative and qualitative aspects of the sleep of a group of 24 eldery people and of 24 very old people have been studied. Regarding the sleep of the eldery person the attention is recalled to two data: the presence of dreams of "erotic" contents in 50% of the subjects and the lack of a substancial difference between the agregate duration of sleep of the adult compared to that of the eldery person. About the sleep of the very old person the A.A. underlines the tendency to sleep more in old age: in this research, one hour more than the eldery. The very old people in the total of examined cases are people that, during life, have always gone to bed "early" in the evening. It is suggestive that only two out of 24 very old people have declared to have "anguishing" dreams.
The Authors have examined the ECG of 190 older than 80 patients. The 5,78% have resulted "normal" and the 12,10% "border-line"; the disturbances of the excitability (67,36%) have been more than those of the conduction (31,04%) among which the Left Anterior Emi-block have been important (12,10%). The myocardial infarction has been infrequent (7,89%) where the Left Ventricular Hypertrophia has been the 20%; the left deviation of the ventricular complexes has represented the 61,57%, the synusal rhythm the 85,26%, the normal rate has been present in 79,47% of the cases.
The Authors through a set of questions have studied some qualitative and quantitative aspects of the sleep of 24 older than 80 patients. These results put in evidence that all the examined longevous people in the whole life, have gone to bed early in the night. Some particular habits in the sleep could be included among the environmental factors useful to a long life.
The Authors describes the case of male subjects who has got a very old age (105) with no particular "biological trouble". Some considerations about it are discussed.
Tre gamma-GT, SGOT, SGPT, urate and triglyceride levels and the mean cell volume were suggested to be markers of alcohol intake in the adult. The value of these markers for the old and the very old (over 80) were investigated. Three groups of different ages of heavy drinkers (under 50, 60-70 over 80) were examined. The highest number of alterations was found in the under 50 group; the lowest in the over 80 (P less than 0.01; chi square M X N method). The mean values in this last group and the number of alterations were similar to those found in a group of no-drinkers of the same age. These markers of alcohol uptake are considered to be of less value for the aged people.
In order to clarify the importance of chronic alcohol uptake in modifying the plasmal lipid levels in the aged people, two groups of males were examined. The people in the two groups had same mean age, and smoking habits (under 10 cigarettes a day) and received the same free ward diet, but had a different alcohol uptake; one group drank more than 150 g of ethanol a day and the other group less than 50 g. The almost only vehicle of ethanol was the red wine. No differences were found among the two groups neither for the cholesterol nor for total lipids, nor for triglycerides. This confirmed that for the aged people it cannot be spoken of an "alcohol induced iperlipemia".
