A study of Sa-Ahm's thoughts on the four-needle acupuncture technique with the five-element theory.

In order to study Sa-Ahm's underlying thoughts on the basis of Yin-Yang and the five-element theory, the 12 acupuncture meridian systems and eight extra meridian systems were investigated in detail. The clinical acupuncture points for Sa-Ahm's four-needle acupuncture technique were also reviewed. The forms of the combinations using the five Shu acupuncture points, which are based on the promotion and control cycles with tonification and sedation, were shown to connect to the acupuncture points, which represent the meridian system itself. However, not all of Sa-Ahm's clinical cases were fully explained by this doctrine, so the five correlations among the meridian systems and the acupuncture points that affect the clinical treatment and the occurrence of disease were determined. The mutual efficacies for Sa-Ahm's clinical cases can be analyzed and explained with correlativity diagrams that include five interrelations.

Primo vascular system in the subarachnoid space of a mouse brain.

Objective. Recently, a novel circulatory system, the primo vascular system (PVS), was found in the brain ventricles and in the central canal of the spinal cord of a rat. The aim of the current work is to detect the PVS along the transverse sinuses between the cerebrum and the cerebellum of a mouse brain. Materials and Methods. The PVS in the subarachnoid space was analyzed after staining with 4',6-diamidino-2-phenylindole (DAPI) and phalloidin in order to identify the PVS. With confocal microscopy and polarization microscopy, the primo vessel underneath the sagittal sinus was examined. The primo nodes under the transversal sinuses were observed after peeling off the dura and pia maters of the brain. Results. The primo vessel underneath the superior sagittal sinus was observed and showed linear optical polarization, similarly to the rabbit and the rat cases. The primo nodes were observed under the left and the right transverse sinuses at distances of 3,763 µ m and 5,967 µ m. The average size was 155 µ m × 248 µ m. Conclusion. The observation of primo vessels was consistent with previous observations in rabbits and rats, and primo nodes under the transverse sinuses were observed for the first time in this work.
