The authors investigated whether ectopic firing is elicited when the lumbar nerve root is exposed to nitric oxide using rats with and(More)

Action of muscles around the knee in walking on a treadmill was studied by electromyography in young normal subjects and in patients with osteoarthritis of the knee. The followings were concluded. The quadriceps femoris stabilizes the knee joint in the sagittal plane, showing higher activity with an increase in faster walking. The tensor fasciae latae and(More)
The effect of 1-hydroxycholecalciferol (1 alpha-OH-D3) on bone metabolism during osteotomized bone healing was investigated. The study based on 19 female patients with gonarthrosis who underwent the high tibial osteotomy. In 10 selected randomly from these patients 1 alpha-OH-D3 (1.0 micrograms/day) was administered before and after the surgery. After(More)
