膝蓋靭帯欠損を作製したウサギに対し, 磁場強度0(対照群), 2, 10および50Gauss(G)の変動電磁場刺激を連日6時間行い, 各群に対し1週ごとに4週後まで肉眼的観察, 病理組織学的検索および力学的強度試験を行った. その結果, 欠損作製2週後における肉眼および病理組織学所見では, 対照群および2G, 10G群で, 靭帯欠損部が依然陥没していたのに対し, 50G群では出血, 壊死像はすでに消失し, 他群に比べ走行性のより一致した膝原線維が増加した. この傾向はその後も持続し, 50G群で最も早期の修復像が認められた. 一方, 引張り強度試験では, すべての刺激群で, 対照群よりいずれの週も高値を示し, かつ50Gが最も高値を示した. 以上の結果から, 50Gの変動電磁場刺激は靭帯の修復機転の少なくとも初期段階に対し, 組織学的, 力学的な促進効果を示すことが示された.

A 4-year-old female toy poodle was admitted with signs of unconsciousness, left head tilt, nystagmus of the left eye, paralysis of the limbs and severe salivation due to falling downstairs. Medical therapy including dexamethasone, diazepam administration was started just after the admission, and then radiography and a CT-scan were performed under xylazine sedation. As a result, the left articular process of the occipital bone was fractured and the bone fragment seemed to compress the cervical spinal cord. The patient received the surgery under GOP anesthesia. The ventral aspect of the occipito-atlantal joint was incised and a few bone fragments around the spinal cord were removed. On the 2nd day of postoperation, the light reflex of the both eyes appeared and the patient recovered consciousness on the 3rd day. On the 7th day, the patient showed a good appetite, and anal reflex and postural reflexes of the right forelimb reversed. On the 14th day, the postural reflexes of all the hindlimbs appeared and the patient could show voluntary walking. At the 8th month of postoperation, the gait and other behaviors were almost normal.
