JOURNAL FREE ACCESSSixty-six healthy subjects with an age range of 14 to 85 years were measured on their skin extensibility and contractility using our original suction method and their values in each age group were compared.
Skin extensibility was given by the maximal extension rate ER%, skin contractility by the residual extension rate ΔER/ER% after removal of negative pressure.
Both values were shown in a wide variety, female values being lower than those of male in every age group.
In general, both ER% and ΔER/ER% were lowered according to the advancement of aging. The difference between the values of age group younger than 60 and those of over 60 was statistically significant. The uncertainty of the measurement of skin elastic modulus was discussed.View full abstractDownload PDF (641K) -

JOURNAL FREE ACCESSSigns and symptoms at the end point of exercise test were evaluated with special concerns on aging. Subjects included 291 patients with suspected ischemic heart disease and 100 patients with clearly documented myocardial infarction. They were divided into 3 age groups: under 49 (I), 50-59 (II) and over 60 years old (III). Exercise test was performed with multi-stage method by using treadmill or bicycle ergometer. End point of exercise test was predetermined according to the recommendation proposed by Japan exercise Cardiology Society. (1) Progressive ischemic ST depression of more than 0.1mV was taken as the end point in 30.9% of group I, 41.7% of group II and 51.1% of group III. (2) Target heart rate (85% of age-predicted maximal heart rate) was obtained in 42.9% of group I, 28.8% of group II and 12.8% of group III. Only 12.8% of cases in group III reached target heart rate and the heart rate at the end point was less than 120/min in 51.1% of this group. (3) Anginal pain (Kattus II°)occurred at the end point of the test in 6.3% of group I, 9.8% of group II and 3.8% of group III. (4) Severe dyspnea was observed in 19% of group I, 29.5% of group II and 32.3% of group III. Incidences of these 4 items were significantly different between group III and others. Other signs or symptoms such as fatigue or arrhythmias were equally observed in every group. Characteristic features of end point of exercise test in the aged were high incidence of appearance of ischemic ST depression, dyspnea or severe fatigue and low incidence of attainment of target heart rate and anginal pain. These findings were equally observed in patients with and without myocardial infarction. Painless ischemic ST depression, dyspnea or severe fatigue should be emphasized as the end point of exercise test and target heart rate should be less than 85% of age-predicted maximal heart rate in the aged.View full abstractDownload PDF (1018K) -

JOURNAL FREE ACCESSAn epidemiologic study has been operating among the residents aged 40 years or over at entry in a rural community, Taisho, located in Kochi Prefecture. The number or the rate of the respondents to the initial examination was 780 of 920 males or 84.8%, and 908 of 1, 012 females or 89.7%. The cohort members initially free of stroke, 772 males and 901 females, were followed up during the period of ten years from July 1967 through June 1977. The incidences of all strokes were 10.47 per 1, 000 person-years≥40 years of age at entry for males and 6.41 for females. Those of cerebral hemorrhage were 2.87 for males and 1.53 for females, and those of cerebral infarction 7.47 and 4.57. By using the age and sex adjusted incidence ratio (SIR), a combination of attributes, and multiple logistic function analysis, risk factors for cerebral hemorrhage and cerebral infarction were assessed. The predisposing factors for cerebral hemorrhage were assumed to be elevated blood pressure, EGG abnormalities, funduscopic abnormalities and alcoholic habits, and those for cerebral infarction to be age, elevated blood pressure, funduscopic abnormalities, EGG abnormalities and albuminuria. Serum total cholesterol level was negatively associated with risk of cerebral hemorrhage in this community.View full abstractDownload PDF (1500K) -

JOURNAL FREE ACCESSIn order to evaluate distinctive features on thyroid function tests in elderly hyperthyroid. patients (EHP), basal metabolic rate (BMR), thyroid uptake of 131I, the serum concentrations of triiodothyronine (T3) and thyroxine (T4) and the value of T3-uptake were measured and free thyroxine index (FT4I) and T3/T4 ratio (ng/μg) were calculated in 24 untreated hyperthyroid patients, caused by Graves' disease, over the age of 61. The results were compared to 34 untreated hyperthyroid patients, caused by Graves' disease, under the age of 39. In 24 EHP, 3 had congestive heart failure, 2 had diabetes mellitus and each one of 2 had myasthenia gravis and gastric ulcer, and anyone of 34 young hyperthyroid patients (YHP) had not other systemic illness. The serum concentrations of T3 and T4 and FT4I were significantly lower in EHP without any other systemic illnesses than in YHP, however there was no difference in T3/T4 ratio between both groups. Although there were no significant differences in the serum T4 concentration and FT4I between in 7 EHP with other systemic illnesses and 17 EHP without any other systemic illnesses, the serum T3 concentration and T3/T4 ratio were significantly lower in EHP with other systemic illnesses than in EHP without any other systemic illnesses and in YHP. The pattern of T4 toxicosis, which is characterized by a normal T3 and an elevated T4 level, was shown in 2 of 7 EHP with other systemic illnesses and was not shown at all in 17 EHP without any other systemic illnesses and in 34 YHP. Our present data suggests that serum concentrations of T3 and T4 in EHP is significantly decreased in comparison with YHP, farther- more peripheral conversion of T4 to T3 in EHP may be decreased in the presence of other nonthyroidal illnesses not by aging.View full abstractDownload PDF (702K) -
