The action of histamine and dopamine neuron in the experiment of morphine-induced conditioned place preference / 中国药理学通报

The drug abuse and addiction is rising currently,it is a bad societal problem as well as a more important medical treatment problem. The experiment of Morphine-induced conditioned place preference is one of the methods detect the intensifying quality of the drug. We deeply studied the action of histamine and dopamine neuron within the brain in the experiment of Morphine- induced conditioned place preference and the correlation under the video frequency tracking-automatism analysis of computer(adopt Mice Track analysis software). It provided a new experiment platform for studying and developing new type medicine of histamine and dopamine.

CT Diagnosis of Spondylolysis of the Lumbar Spine / 实用放射学杂志

Objective To improve the knowledge of CT appearances of spondylolysis of the lumbar spine.Methods 32 patients with lumbar spinal spondylalysis were examed by Elscint 2400 CT.CT appearances were analyzed.Results The CT feature of spondylolysis was loop-broken sign.Spondylolisthesis was present in 25 cases,the CT mainfestations included the increased anterior pasterior diameter of spinal canal,wich sign,deformity of vertebral canal and pseudobulging disk.Other features included asymmetrical zygapophysial joints.Conclusion “loop-broken sign” is a relatively specific CT appearance of spondylolysis of the lumbar spine,which is significant in diagnosting spondylolysis without spondylolisthesis.
