Research into the existence of SERDP has been carried out by many workers with a back-ground in modern western medicine. However, it has not yet been possible to prove their existence and there is a great lack of accordance in the arguments presented. The results were as follows: 1) SERDP and Nerve Histology in Each of the Experimental Animal: The local anatomy of the sampling points showed white color nerves in the subcutaneous and muscle tissue. Nerve tissue was present at all SERDP. Nerve bundles were demonstrated at SERIP at the following rates: rabbit 42.9% , and dog, cat, rat and mouse 28.6% . Nerve tissue was most abundant in the subcutaneous tissue, and less so in the muscle layer. Medullated nerve tissue was predominant. Nerve bundle thickness (the following are all average value) were 11×14μ in the dog; cat 8.9×17.0μ, rabbit 8.6×19.4μ, rat 8.4×16.7μ , mouse 4.2×8.9μ and the depth of nerve bundles from the skin surface was: dog 327μ, cat 206.5μ, rabbit 181.3μ, rat 244.5μ and mouse 138.8μ. 2) Relationship between Blood Vessels and SERDP: It was confirmed that 35.9% have a relationship with blood vessels. 3) Relationship of Lymph Vessels to SERDP: 17.9% of SERDP had associated lymph vessels, an association only about 50% of that for blood vessels. 4) Relationship of Connective Tissue to SERDP: Tissue from SERDP and SERIP was taken and stained by the Masson Trichrome method. No specific histological changes were observed. 5) Relationship of Catecholamines to SERDP: A mild increase in catecholamine activity of the SERDP was observed when compared with SERIP. 6) Relationship of SERDP and Macroscopic Vital Staining for Nerve Tissue: Long Chinese acupuncture needles were deeply inserted, excised, and the subcutaneous tissue studied. White nerve fibers were seen to have a fairly high association with SERDP. This was confirmed with vital staining using Leucomethylen blue. 7) Relationship between SERDP and the Phenomenon of Needle Sensation (Tokki, Hibiki): Japanese and Chinese acupuncture needles were placed in SERDP and SERIP in human subject and twirled 5 times to test for the existence of needle sensation. Results were as follows: a) Japanese needles, SERDP 90.5%, SERIP 50.5% b) Chinese needles, SERDP 99.5%, SERIP 65%. From the above, it was demonstrated that macroscopically, histologically, and physiologically, SERDP have an intimate relationship with nerve tissue.
