ジャーナル オープンアクセスThe effects of the conditioning electrical stimuli applied directly to the nerves (45 Hz, 0.1ms, 15 min) innervating the meridian points of Yin-Hsiang (infraorbital nerve), Ho-Ku (radial nerve) and Zu-Sanli (common peroneal nerve) on the pulp-evoked jaw-opening reflex were investigated in the Wistar albino rats. The threshold change of the digastric electromyogram activity in the reflex was monitored during and after the conditioning stimulation. There was a gradual change in the threshold and the effect remained for several minutes after the cessation of the conditioning stimulation. In case of stimulating each ipsilateral nerve, the effective degree was 210 to 260% of the control. On the other hand, when each contralateral nerve was stimulated, the degree was 170 to 200% of the control. The reflex was also evoked by the low intensity of the direct infraorbital nerve stimulation. The threshold value of this reflex was not altered by the conditioning stimulation of each nerve.抄録全体を表示PDF形式でダウンロード (1506K) -

ジャーナル オープンアクセスFor the treatment of the moyamoya disease, we developed a surgical procedure of Encephaloduro-aterio-synangiosis (EDAS), which was conducted in 15 cases on 23 sides. As a result we obtained improvement in cerebral vascularization as well as in neurological and electroencephalographic findings in all cases. This report describes an introduction of the procedure and a review of the postoperative cerebral angiograms. Cerebral revascularization by EDAS proceeded on the following steps, and it was confirmed that efficient cerebral revascularization could be obtained 6 months after the operation in almost all cases following the steps: 1) dilatation and increase of dural artery, 2) dalatation of donor scalp artery, 3) cerebral revascularization with the development of visible fine spontaneous anastomoses between the donor scalp artery and the cerebral arteries and 4) further dilatation of the donor scalp artery and retraction of the abnormal rete vasculosum at the base of the brain.抄録全体を表示PDF形式でダウンロード (2381K) -

ジャーナル オープンアクセスAn investigation was made to determine the effects of the addition of selenium to the silver-tin amalgam alloy. The addition of 0.2 wt% to 0.6 wt% selenium in the alloy completely eliminated the cytotoxicity, evaluated by the 51Cr release assay and morphology, of the silver amalgam on the L cells and JTC-12 cells. The physical properties of the amalgam containing 0.2 wt% selenium in the alloy were tested according to the American Dental Association Specification No. 1 for Alloy for Dental Amalgam and were found to meet the requirements.抄録全体を表示PDF形式でダウンロード (826K)
