Furthermore, in the CTA rats, compared with water stimulability, FLI neurons of SON and DMV induced by sucrose stimulability had had much more expressions.6 When the same sucrose stimulability was given, FLI neurons expressions of SON, DMV and LH in the CTA rats were much lowwer than that in the control rats.Conclusions:1 CTA had an inhibitory effect on small intestine peristalsis, indicate taste preference has an effect on small intestine peristalsis, and inhibitory effect induced by CTA is corresponded with US, this effect may have relations with vagus efferent never and humoral regulation.2 In the electrophysiology experiment, discharges of vagus efferent never in the CTA rats are much more than that in the control rats, indicates taste and taste preference may regulate small intestine peristalsis via vagus nerve, and dicharge can continude 1 hour, indicate humoral regulation also exists in the regulation.

结论1建立味觉厌恶对小肠运动有抑制作用，提示味觉嗜好性对小肠运动有影响，而且味觉厌恶引起抑制作用是与条件刺激成对应关系的，味觉刺激引起的小肠蠕动的抑制作用可能与迷走神经传出神经及体液调节有关。2在电生理实验中，CTA大鼠迷走神经传出放电高于对照组的大鼠，提示味觉及味觉嗜好性可能是通过迷走神经对小肠运动进行调节的，放电至能持续60min，表明味觉及味觉对小肠运动的调节中还有体液调节的参与。

It is suggested that there are some Glu sensitive neurons in sublayer Ⅱaf of pigeon optic tectum,the most of which show excitation to exogeous Glu.These data observed in slices provide a strong evidence that Glu may act as a neurotransmitter involving in the activity of the sublayer Ⅱaf neurons in pigeon optic tectum.

Barrington's nucleus that located in the pontine dorsolateral tegmentum is an important site for controlling voiding in the mammalian brain and is often referred to as pontine micturition center. Barrington's nucleus sends direct projection fibers to the sacral parasympathetic nucleus in which parasympathetic preganglionic neurons innervating detrusor muscles of the bladder are distributed. Electron or chemical stimulation of Barrington's nucleus clicits bladder contraction and increases discharges of bladder postganglionic nerve. Conversely, lesion of the nucleus results in a permanent inability to empty the bladder. On the other hand, an area located just ventral to Barrington's nucleu has been reported to send projection fibers to the ventrolateral group of Onuf's nucleus in the caudal lumbar cord segments; the vetrolateral group of Onuf's nucleus is mainly composed of pudendal motor neurons innervating the external urethral sphincter muscle.

Barrington's核发出纤维投射至支配膀胱逼尿肌的骶髓副交感核，毁损该区可导致动物永久性失去排空膀胱的能力；而电刺激或化学刺激该区可引起支配膀胱的节后纤维放电增加和膀胱逼尿肌收缩。D区是紧邻Barrington's核腹侧的一团神经元，它发出纤维投射至腰骶髓Ounf核的腹外侧群，而Ounf核的腹外侧群主要是由支配尿道外括约肌的阴部神经运动神经元组成。

LTP manifests as a persistent increase in response of postsynaptic neurons to subsequent stimulation after tetanic stimulation of the presynaptic neurons.

本项目在我们以往研究的基础上，探讨与脊髓背角LTP表达和维持相关的几个重要问题。

Ception can enter the dorsal-most laminae I and II but not grow further ventrally. As for the waiting period and the correct projection of the NT- 3 (neurotrophin-3)sensitive Ia neurons and other neurons, it is possible that other guidance cues might make more contribution.

至于腹侧投射性的神经营养因子习（neurotrophin3，NT3）敏感性肌梭h类神经元和其它神经元轴突的等待期和定向投射，则更有可能是在其它类型的导向因子的共同参与下进行的［81

RESULTS: The mild traction group showed angulus anterior individual neuron slightly engorged, neuron and nerve fiber morphous was normal essentially; individual substantia alba demyelinates in fragmentis; medullary sheath and auxiliary fibers of nerve root were hydropsia slightly without conspicuous myelinolysis. The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.

And they systematically studied the effect of the activate spleen-energy law on digestive and absorptive function, it is confirmed that the activate spleen-energy law have significant regulation effect on the action and secretion of gastrointestinal tract. Recently, we established the juvenile rat model with anorexia by imitating the major cause of children and found that the CCK-8S concentration in hypothalamus and periphery blood of the anorexy model was obviously increased .We also found the appestat that the spontaneous discharge frequency of LHA neurons was decreased and the spontaneous discharge frequency of VMH neurons was increased.

近几年，我们采用病因模拟法成功建立了幼龄大鼠厌食模型并发现该模型下丘脑和外周CCK-8S水平显著增高，食欲中枢——下丘脑外侧区神经元自发放电频率减低和下丘脑腹内侧区神经元自发放电频率增加，临床治疗小儿厌食有可靠疗效的运脾复方不仅可调节外周血中与摄食有关的肽类激素水平，如降低CCK-8S水平，而且能调节下丘脑食欲中枢神经元的自发放电频率。

Autoradiographic studies have demonstrated that adenosine A1 and A2 receptors are expressed in the spinal dorsal horn, both on the post-synaptic SG neurons and the central terminals of the primary afferent neurons.

放射自显影的结果表明A_1和A_2受体都分布在脊髓背角，包括突触后SG神经元和初级传入神经元的中枢突，而A_1受体集中分布于胶状质。

The split between the two groups can hardly be papered over.
