Since Harrison succeeded in 1896 in the surgical treatments (decapsulation) of acut nephritis post scalratina, his measures have been carved out with success and proved to be successful by his many fallowers in the cases of oliguria and anuria. Thenceforth, on the problem of the good results of this treatment (here meant decapsulation) many theories were explained but none determinable. In the recent time, the greatest urologic authorities, Casper und Kummel, maintained the nervous theories, that is to say, “The decapsulation causes at the sane time nothing more than sympaticoektomie of kidney.” But the foundation, on which their theories stand was then very feable, until Ernst Lehman's resultful anatomical study was made public in the recent time (1926). Independent on them, I have been studying for several years the innervation of ren capsule by means of Cajal's (renewed by him, for the purpose of peripheric nerve system study, in 1921) silver impregnating method and found out the following additions to the Lehman's results and somewhat contributions on the problem of decapsulation, for I have also several clincal experiences on this treatment.
1. The ganglion; (a) lying in the connective tissue of capsule, (b) in several number, (c) round, oval or spindle formed, (d) a-mono-bi or poly poled, (e) consiting of very flat nerve cells lying in one layer, (f) between the ganglions connected with the nerve fibers comming out the ganglion, (g) several size, depending upon the number and the size of the nerve cells consisting of the ganglion, (h) their situation undependent upon the blood vessel courese
2. Nerve cells; (1) very flat, (2) round or oval, star formed (3) a or mono-or poly pled being somewhat modified by their situation in the ganglion. (4) every cell has a ronnd shaped small nucleus in its central part (5) the nucleus above mentioned has several (1-2-3) nucleus-bodies in itself (6) around the cell membrane visible, (7) protoplasma impregnated not homogenious nissl's nucleus good impregnated. (8) except the nerve cells belonging to the ganglion above mentioned, many small but good constructed ganglion cells stand solitude in the course of nervefiber bound coming from ganglion.
3. Nerve fibre; (1) dendrite almost branched into several number fibres direct after he comes out from the cells, and make fibre-net-work among the cells by its branching, which called “inter-cellular fibrillar” after Ramon. Y. Cajal. (2) Some dendrits branched and ended freely among the cells. (3) Achsencylinders no branch in the wide of ganglion, further branched repeatedly into many small branches in every time and changed to nerve-fibres, more-over to neurofibrills. (4) all nerve fibres belonging to those above mentioned are of unmyelinated, Remark's fibre. (5) Remark's fibre, every where along its course, connected with nodulous enlarged points, as it mere sweet potato runners. If we search after the sympathetic nerve fibre from the central part to peripheral wards, about or in the near of its end-branch we meet the another endbranches of the nerve belong to another ganglion, so we conclude that the capsule is twined round by the neurofibrillen in this way.
4. Endapparat, The nerve fibre, branched repeatedly in the manner above mentioned, reached the figure of neuro-fibrillen. Direct before its ending, the neurofibrillen splited into several number, and each ends to the connective tissue cell-nucleus in the manner it embrace the nucleus or through-passing the nucleus, further united to the fibrework of connective tissue cell protoplasma. (2) Some fibres go to blood vessels, direct after reaching here, they branch almost rectangulaly and each branch runs aside the blood vessels in the long distance, sending many times small branch to the vessels, finally split into many branch, that is neurofibrille, ending among the adventitia cells.
From the facts above mentioned, I can conclude that the kidney capsule
