摘要:

Anthropometric measurements (weight, skinfold thickness at triceps, subscapular and dorsum of the hand and circumference of upper arm and abdomen) of 126 aged subjects, studied in four groups, are reported. The relationship of any of these anthropometric parameters with energy intake was not significant in the majority of the groups. Abdominal circumference was the only measurement which showed a significant correlation with body weight in the males and females of the four groups. The use of abdominal circumference as an indicator of nutritional status needs further study.

摘要:

We have studied tyrosine aminotransferase in the liver of adult and old rats. Thermostability and trypsin action were not modified, and no charge differences have been found by isoelectric focusing between ‘adult’ and ‘old’ enzymes. Inducibility by glucocorticoids was increased in vivo in these 27- to 31-month-old rats, but not in vitro, in cultured hepatocytes. Moreover, we have shown the absence of ‘cross-reacting material’ for tyrosine aminotransferase in senescent rat livers. The rapid turnover of this enzyme may explain the apparent absence of alterations d

摘要:

There was little or no improvement in the median survival times of Drosophila melanogaster fruit flies when fed high concentrations of the singlet oxygen quenchers, β-carotene and l,4-diazabicyclo(2.2.2)octane. Singlet oxygen was presumably generated endogenously by inactivating catalase with 3-amino-1,2,4-triazole and feeding NaOCl. This treatment caused a reduction in median life span of from 14.3 to 25% depending upon the NaOCl concentration used. β-Carotene and l,4-diazabicyclo(2.2.2)octane gave partial protection against the singlet oxygen generated by NaOCl. These data are interpreted to mean that normally occurring singlet oxygen does not contribute to senescence in Drosophila but that artificially produced singlet oxygen accelerates the rate of agin

摘要:

Male and female Wistar rats (n = 140) age 1.5 months were maintained in either wheel-cage units or cage units for their entire life span. Voluntary wheel exercise significantly increased the mean longevity of both male and female rats compared with that of control rats. Between and within groups, growth duration was positively related to longevity, and growth rate was negatively related to longevity. These factors may explain differences in longevity between exercise and control groups and differences in longevity between male and female groups. These factors of growth, here defined in terms of body weight increment, may possibly account for many instances of group differences in longevity

摘要:

The influence of food ingestion and time of day on the serum levels of B12, folate, iron and total iron-binding values was studied. Food intake had no influence on serum B12, serum iron and total iron-binding capacity (TIBC) levels, but serum folate rose rapidly. Serum B12 showed no change with time of day. Serum iron and TIBC fell significantly from 8 a.m. to 8 p.m. Folate initially rose significantly over 5 h then fell at 12 h, but this fall did not reach statistical significance. Over a period of 1 year serum iron fell, but TIBC showed no significant change. Subjects without pernicious anaemia but with low B12 levels showed no significant change in serum B12 over 4 years.

摘要:

An analysis of the waiting list of patients in the geriatric department waiting for transfer to welfare residential accommodation revealed that those who lived alone had no close relatives, had to pay rent for their accommodation and would need assistance with fees had to wait the longest for welfare accommodation while those who lived with relatives or who had close relatives, who owned their houses and appeared to be able to manage full fees gained access to welfare accommodation homes more quickly. It also was apparent that those who were mentally confused were disadvantaged in that they took longest to transfer to a residential home. There should be a reappraisal of priorities for transfer of patients from hospital to a welfare home.

摘要:

A manual dexterity test was performed in a population of elderly women. Obese subjects with hyperostosis frontalis interna (HFI) had a poorer performance than subjects with either HFI alone or obesity alone. The combined effects of cerebral arteriosclerosis and HFI is suggested as a possible explanation for these findings.
