    The estimation of maximal oxygen intake from heart rate and oxygen intake during submaximal works at different air temperature conditions was investigated, and as a result, a nomogram available for the estimation at 20°C, 30°C, and 40°C has been published (SATO, SAKATE & TAKASAKI '76). However, this nomogram is responsible only for males. The first purpose of this study is to improve the nomogram with female data and to make it responsible for both sexes.
    The second purpose of this study is to estimate maximal oxygen intake from the nomogram by MARGARIA et al. ('65) at different air temperature conditions, and to investigate air temperature effect on it. The large deviation up to 5.8ml/kg or 13.6% from directly measured maximal oxygen intake and no significantly correlation between directly measured and indirectly estimated values were observed. Therefore, the estimation of the maximal oxygen intake from the nomogram by MARGARIA et al, was concluded not to be sufficient comparing with that from the nomograms described here, though air temperature factor was confirmed statistically to produce no significant effect on the estimated maximum from their nomogram. The instability of oxygen intake per unit of body weight during submaximal works, which was calculated to attain to 8% of the mean value, and large fluctuations in heart rate gradient even within the individuals, which were expressed by 10% in coefficient of variation, were suggested to be main reasons for the insufficiency in the estimated maximal oxygen intake with the nomogram by MARGARIA et al. ('65).

  • Changes in the Fatty Acid Composition of Human Sebum with Age

    Specimens of human sebum were obtained from the forearm of 132 subjects assigned to one of five groups. An analysis of the total fatty acids of these sebum specimens revealed two patterns based on the content of isopentadecanoic acid (iso 15:0) and ante iso-pentadecanoic acid (ante 15:0). Type A was characterized by a content of iso 15:0 greater than ante 15:0. Type B pattern showed a content of ante 15:0 about four or five times greater than iso 15:0. These patterns varied as function of subject age. From the relationship between these two patterns and age groups, it appears that the content of iso-pentadecanoic and ante iso-pentadecanoic acid in human sebum is age-dependent. Also, the ratios of the content of these two acids are inverse as a function of subject age.

    The skin in the cheek of a cynomolgous macaque was observed with a scanning electron microscope. The following results were obtained concerning the hairs:
    1. A great part of hairs in the cheek grew singly.
    2. Various hairs in size grew in the cheek.
    3. The breadth between the free margin of an upper cuticle and that of a lower one was narrow in thick hairs.
    4. The border between the cuticles which were transversely in contact with the other was not clear in many cases.
    5. Membranous cristae were observed at the free margin of the cuticle on the surface of hairs.
    6. The cuticle was observed in layers on the cut surface of hairs.
    7. The cuticle was closely in contact with others.
    8. On the cut surface of hairs small processes were observed at the margin of the cuticle.
    9. Many fibrous structures were observed on the surface of the cuticle.
    10. Many small pores were scatterlingly observed on the surface of the cuticle.
