    Notes: Summary Spinal cord atrophy takes on several different forms which correlate closely with specific clinical features. The majority of them, however, can be categorized into three distinct patterns, diffuse (transverse myelopathy), hemi-(Brown-Sequard syndrome), or anterior (anterior spinal artery syndrome) atrophy. Until recently, the differential diagnosis had been made solely on the neurological examination. We present three cases of spinal cord atrophy, one in each category. Spinal computed tomography with metrizamide appears to be a reliable supporting diagnostic method for spinal cord atrophy.

    Notes: Abstract The effect of amezinium, a new antihypotensive agent, and hormonal treatment on the female rabbit urethra was investigated. Cumulative dose responses were obtained for amezinium and norepinephrine on strips of muscle from the urethras of ovariectomized female rabbits by means of the tissuebath system. Amezinium enhanced the response to electrical field stimulation and showed a direct contractile response on the urethra. These responses were only about 20% of the maximum norepinephrine response. The contractile response to amezinium was completely blocked by prazosin. When rabbits were pretreated with estrogen, with or without progesterone, for 4 weeks, the response to amezinium increased to 40% of the maximum norepinephrine response. Although amezinium enhances muscle contractile responses to electrical stimulation, this effect is strong when amezinium is used alone; concurrent estrogen treatment improves the effects of amezinium.
