Using CdS, the nasal reflexion photoelectric plethysmograph (R.P.P.) was made. This apparatus, tiny and extremely sensitive. recorded accurately the movement of blood flow through the mucous membrane of the human inferior turbinate as volume pulse.The tracing was simple and accurate. The following results were obtained.1) Two kinds of wave fluctuations were found on the R.P.P. of the nasal turbinate mucous membrane. One is the so-called respiratory fluctuation without having changes in the amplitude of volume pulse, and the other is the spontaneous fluctuations of longer periodicity at the time of quiet respiration of healthy persons.Respiratory fluctuation was remarkable when the inspiral air was cold. but it was not so remarkable on the finger R.P.P. Spontaneous fluctuations of the inferior turbinate on both sides are. in many cases. synchronous but it is not so between nose and fingers. The movements are bigger in nervous persons. but are seldom found in arteriolosclerosis.2) The vasomotor reflex which was brought about by means of deep breathing. breath holding. mental calculation. cold stimulation etc. showed remarkable vasoconstricting tendency on the finger plethysmogramm. However. the tendency of plethysmogramm of the nasal mucosa was rather weak and the total blood volume was considerably redu ced. Cold stimulation was especially. characterized by an increase of blood volume of the nasal inferior turbinate.3) The wave-forms of the R.P.P. of inferior turbinate showed more even rounded curve with less pinnales and dales than those of fingers. This fact is supposed to be attributable to the effect of endocardial pressure. which influences stronger nasal inferior turbinate than on fingers.4) It can be said. therfore. that the peripheral blood circulation in the nasal mucoa of inferior turbinate regurates itself by virtue of the A.V.A.. the polster-artey and the sinus plexus etc.
