Novel Anatomic Structures in the Brain and Spinal Cord of Rabbit That May Belong to the Bonghan System of Potential Acupuncture Meridians
Bibliographic record
Abstract
Novel threadlike structures of 20 to 40 microm in diameter were observed running afloat in the cerebrospinal fluid of the brain ventricles and the spinal central canal of a rabbit. We developed an effective in situ staining technique using hematoxylin to visualize the threadlike structure. The presence of the rod-shaped nuclei in the threadlike structure was confirmed by various nucleus specific staining dyes such as 4',6'-diamidino-2-phenylindole, propidium iodide and yoyo-1. The threadlike structure was surrounded by a cellular membrane, whose presence was visualized by using 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate staining. The location, diameter, optical transparency and the presence of rod-shaped nuclei in and the surrounding membranes of the threadlike structure were consistent with a nerve Bonghan duct. The Bonghan duct was claimed to be the extension of the physical substance of acupuncture meridians and to be a distinct type of circulatory system present in mammals. Although Bonghan theory has not been reproduced for a long time, recently, some portions of the Bonghan duct network were confirmed in various organs in mammals including blood vessels, lymphatic vessels and enteric organs. The novel threadlike structure in the central nervous system, more specifically in brain ventricles, is one in a series of findings in an attempt to rediscover the Bonghan duct network.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
