RESUMEN
@#ObjectiveTo test the effect of human tremor detector in clinic based on the principle of photoelectrical transformation.MethodsFifty-five subjects including normal youth and elderly persons, patients with Parkinson's disease (PD), hyperthyroidism and cerebellor ataxia were tested with human tremor detector. The displacement, frequency spectrograph, velocity and acceleration of both hands in four kinds of postures and action were involved.ResultsThe physiological tremor and pathological tremor in different kinds of patients were significantly different (P<0.05). Especially in PD, both quantitive and qualitative data had a significant difference.ConclusionHuman tremor detector can provide the evidence for early diagnosis of PD.
RESUMEN
An observation of nerve terminals in the induced glioblastoma of mouse was made by Nonidez and Glees impregnation method.In the marginal zones of the glioblastoma innoculated in the brain or muscle,nerve fascicles of various sizes with or without the blood vessels could be seen. In some case the nerve fibers formed a perivascular plexus through the perivascular space and some nerve fibers terminated on vascular walls.The nerve fibers within the tumor seemed to be related to those nerve fibers distributed in the brain tissue near the tumor or in the subcutaneous tissues, hair follicules of muscles around the tumor, hence, we suggest that the nerves whthin the tumor were growing in from the surrounding normal tissues.The amount of the nerve fibers was more abundant in the periphery than in the center of the tumor, the nerve fibers ran through the stroma or parenchyma of the tumor and gave out many branches to the tumor cells, we have also observed various types of nerve terminals for example: bulbar, isolated bifurcated, fusiform,circular, branched, brush-formed and club-formed endings.According to the findings mentioned above, it is concluded that the induced glioblastoma of mouse is innervated by nerve endings.
