[A quantitative study on mandibular incisor point border movement between the immediate complete denture wearers and the second complete denture wearers]

The mandibular incisor point border movement orbits of 20 patients wearing immediate complete dentures for 3 months and the same patients wearing the second complete dentures for 3 months were raced by SGG then measured and analysed.The results showed that the ranges of mandibular incisor point border movement of patients wearing immediate complete dentures for 3 months were significantly narrower than those of the same patients wearing the second complete dentures for 3 months (P<0.01).The ratio of the former to the latter was only 59.00%-69.96%.It could be concluded that the ranges of mandibular incisor point border movement of immediate complete denture wearers were limited.Thus the immediate complete dentures were transitional dentures and only used for treating purpose.The patients must have another pair of complete dentures after 3 months interim.

[Influence of electroacupuncture on ACh content and AChE activity in the spinal ganglia of rat].

The spinal ganglion a cell body storage of somatic primary-sensory neurons, is considered as an important region for neurochemical research of primary afferent nerves. The present experiment aims at the observation on the Ach content and its changes in the ganglia of 128 rats by means of biochemical methods under the effect of administration of Neostigmini and application of electroacupuncture. It is found that there are evidence of existence of Ach in the ganglia and when the AchE activity in the periphery nerve system is inhibited, the Ach content of ganglia rose. In addition, during acupuncture (applied at acupoint "Huantiao") analgesia, no apparent changes of Ach content can be visualized in spinal ganglia, however, the level of AchE activity goes up evidently. The foregoing results indicate that in the somatic primary-sensory neuron Ach is one of important neurotransmitters which may influence and take part in the transmission of sensory information through primary afferent nerves.
