The innervation and distribution of 5-HT cells in gastric wall of rabbit and rat were studied by means of histochemical techniques of monoamine fluorescence and cholinesterase. And the morphological relation between them was investigated using the consecutive method for demonstrating the fluorescence and ChE on the same section. At the fundic gland, 5-HT cells were in contact with both the adrenergic and cholinergic axonal terminals. There are adrenergic and cholinergic terminals to innervate the gland cells of fundic gland, partial fundic gland the dual axonal terminal are identical in their localization and morphological outline. The loyer of muscle and smooth muscles surrounding the arteriole in various stomach layers were innervated by both adrenergic and cholinergic terminals, some of them are superimposed at the samelocalization. There are a lot of nsChE nerve ending network in gastric lamina propria beneath epithelium of gastric mucous membrane, it was discussed about their sensory nature in this paper.

Fifty two adult male rats were selected for the investigation the adrenergic and cholinergic innervation of rat heart by means of histochemical demonstration of catecholamine fluorescence and acetylcholinesterase (ACHE). Consecutive method was employed on the same section to demonstration the relation between the distribution of the sympathetic and parasympathetic nerves in various parts of rat heart, e. g. atrium, ventricular myocardium, valves, epicardium, endocardium, atrioventricular node and coronary arteries. Adrenergic and cholinergic terminals innervated all parts dually. By comparing the photographs demonstrating the fluorescence CA and AChE on the same section treated by the consecutive method, we found that the location, the density and morphology of both types of nerve terminals were more like. In other words, under light microscopy the localization of both terminals can hardly be distinguished from each other. Such kind of morphological relation may strongly support the results of interaction between sympathetic and parasympathetic nervous systems in physiological and pharmacological experiments of heart.In the cardiac ganglia there are some small intense fluorescence ceils (SIF-cells) lying besides the postganglionic cholinergic cells of the parasympathetic nervous system. Both kinds of cells were shown in close contact with each other in the same section with consecutive method. This morphological relation provided an evidence that catecholamine containing SIF-cells may control and regulate the neurotransmission of parasympathetic cholinergic neurons.

Objective To investigate the efficacy of computer-assisted postural balance training system combined with Bobath balance training on balance disorders after cerebellar stroke.Methods Forty patients with balance disorders after cerebellar stroke were randomly divided into either a combined training group or a control group (n =20 in each group).The control group was trained with Bobath balance training and routine rehabilitation treatment.On the basis of this,the combined training group used the computerassisted postural balance training system for rehabilitation treatment.The balance function,activities of daily living and motor function were evaluated with the Berg Balance Scale (BBS),modified Barthel Index,mBI)and Fugl-Meyer Assessment (FMA) before and after treatment,and the computer-assisted postural balance training system was used to conduct the postural balance ability according to the center of gravity track length,rectangle area of track,and peripheral area of track.Results There were no significant differences in various indexes before treatment between the patients of both groups.The scores of BBS,mBI and FMA after treatment were increased obviously (all P ＜ 0.001).The the center of gravity track length,rectangle area of track,and peripheral area of track were decreased compared before treatment (P ＜0.001 or 0.05).In addition to the FMA score,all the indexes of the combined training group after treatment were significantly better than those of the control group (all P＜0.05).Conclusions On the basis of Bobath balance training,using computer-assisted postural balance training system can obviously improve the balance disorder and extremities motion ability after cerebellar stroke,and thus improving the activities of daily living in cerebellar stroke patients.
