Airpocket現象に関する研究 (第8報) 内臓疾患に於ける, 特にDermatothermogram (D.T.G.) による観察

抄録

The author studied on the “airpocket phenomenon” using the so-called Dermatothermograph which had been previously devised and named by professor F. Matsunaga. The airpocket phenomenon is defined by the professor as a temperature drop of the skin at the paravertebral part of the various visceral diseases. This phenomenon in one of the viscero-vegetative nerve reflexes occurring from the interrelation between the interoceptive fibres exsisting in the visceral nerves and sympathetic nerves in the spinal cord itself.
Finding the paravertevral parts where the airpocket phenomenon is observed, the examiner can determine the diseased viscera from the segementation of the spinal cord. This henomenon is therefore believed to be useful not only for diagnosis but also for therapeutic management.
At the begining of this study, the drops of the skin tmeperature were measured with a pyrometer, a thermocouple (copper-costantan) which had been used by Dr. IGARASHI in our clinic. This procedure, however, was too complicated and the author therefore has. experimented by the Dermatothermograph, a device which employed thermister with an automatic balancing recorder by electron tube. This unit was planned by Prof. MATSU NAGA and his co-workers, and the management of this machine is much more simple. and precise than the pyrometer above-mentioned.
Observing the Dermatothermogram (DTG) recorded by this apparatus, the examiner can compare the present condition with the previous condition in each diseases.
This phenomenon was found to be positive 100 per cent in a cases of pleurisy, 91 per cent in cardiac diseases, ober 80 per cent in diseases of the bile ducts, stomach and. duodenum (particularly in peptic ulcer) and 78 per cent in pulmonary tuberculosis even.
The paravertebral segments in which the airpocket phenomena are observed are determined in each viscerum as follows:
Bile duct: (right) T_2-5-7-8, (left) T_2-3
Stomach: (left) T_2-5-7-8, (right) T5-7
Heait: (left) C_6-7, T_2-3-4, _9-10-11-12.(right) T_{2-4, 9-12}
Lung: C_6-7, T_2-3-4, _8-11-12 (the site depending upon the site of the lesion)
Pleura probably: C_6-7, T_7-8, _10-12 (the side depending upon the lesions side)
Kidney: C_6-7, T_7-8-10-12 (the side depending upon the lesions side)
(C…cervical, T. thoracic. The segment underline are the sites where the phenomenon is observed most frequently and remarkably.)
The segment related with above-mentioned viscera may differ in some points from the previous reports described by other workers.
The chief results from the previous reports of his work are following:
1) In the diseases of the upper gastrointestinal tracts, the airpocket phenoemenon is. observed not only in the middle thoracic segent but also more widly from the upper to the lower parts of the thoracic segments.
2) In the diseases of the intrathoracic organs, the airpocket phenomenon is observed not only in the upper thoracic segments but likewise also in the lower cervical segments.
3) Airpocket phenomenon is recognized in the cases of renal diseases not only in higher thoracic segments, viz. T_8-9-10, than expected from the literature previously described but also in the upper thoracic and lower cervical segments.
In order to clarify these results different from many previous papers of other workers, it may be necessary to mind the existence of a secondary genetic mechanism which is caused by the complications.
