In this report, the observations of “Airpocket Phenomenon” by DTG (Dermatothermogram), which can record the skin temperature of paravertebral region automatically by the using of thermister, was descrived. Moreover, in order to clarify the pathological physiology of the “Airpocket Phenomenon”, the influences upon this phenomenon by the administration of the various sympathomimetic and parasympathomimetic drugs and by the changes of the bodily position were studied. Then the relation between the “Airpocket Phenomenon” and the results obtained pharmacologically from the function test of autonomic nervous system was also investigated. The results obtained from these experiments were as follows:
1) The average skin temperature of the paraverteval on the 10 normal subjects was highest in the 5 th paravertebral part on the right side and 4 th on the left.
2) The “Airpocket Phenomenon” was found in 93 (77.5%) out of 120 cases with various visceral diseases, but this positive cases were observed at the considerable wide area of the paravertebral region.
3) The “Airpocket Phenomenon” was relieved or disappeared by the subcutaneous injection of 2-benzyl-imidazoline or hexamethonium bromide. On the contrary, atropin sulfate strengthened “Airpocket Phenomenon” in 60 per cent of the examined cases. While adrenalin relieved or disappeared the “Airpocket Phenomenon” in 67% of the patients.
4) By pressing the axillar part of the side at which the “Airpocket Phenomenon” was most positive, no definite changes were found, but the pressure of it at the healthy side made almost relief or disappearence of the “Airpocket Phenomenon”.
5) According to the pharmacological function test of sympathomimetic and parasympathomimetic system, patients who showed positive “Airpocket Phenomenon” were generally in a condition of the sympatheticotonia.
