The total and segmental microphotoelectric plethysmographs (—m; MPPG) were developed by using CdS photoconductive cells and rabbit ear chambers. The former were obtained from a whole micro-circulatory unit and the latter from segmental vessels in the microcirculation of which images were projected on a focusing glass. Both record the dynamic behaviors of the microcirculation continuously and quantitatively, and permit microscopic observations. The total and segmental MPPGs reflect various fluctuations of vasomotion and of blood flow in the microcirculation. In the microcirculatory blood flow, rhythmic fluctuations of 4–8, 8–12, and 0.5 or fewer counts/min were distinctly noticed in addition to the basic rhythm of 1–3 counts/min. agrR wave; &szligbeta;R wave; ggrR wave; omegaR wave; rhythmic fluctuation in the microcirculation Submitted on April 29, 1964

Attempts to study the degree of pulmonary dysfunction in children and adolescents have been greatly handicapped by the lack of adequate standards for reference.

It is well accepted from studies on adrenal cortical activity that stressful performance results in hypersecretion sometimes followed by hyposecretion. This physiological mainfestation has been called the "adaptation syndrome" (1). Along this line, two investigations were made to demonstrate the special diurnal rhythm in adrenal cortical activity of healthy men; in one of them 17-ketosteroid output in urine was followed throughout the day and night (2), and in the other circulating lymphocyte changes were seen in a successive period of 24hours. On the other hand, evidence was obtained that eosinopenia shows a good response to cortisone, a synthetic sugar-active 11-oxygenated corticosteroid which is known as an important product of adrenal cortex (4). Furthermore, Thorn Test based on the eosinophil change has been applied in many hospitals (5). So it was thought worthwhile to show the evidence of diurnal changes in the number of circulating eosinophils which is intimately related to the activity of the sympathic-adrenal and the pituitary-adrenocortical system (5).
