摘要:The normal ultrastructure in the middle part of NTS of rat was examined with EM. Results: The most common type of axo nal terminals was mainly contained round clear vesicles (R terminal).The terminals with clear pleomorphic vesicles (PL terminal) and terminals contained large granilar vesicles (LG terminal) were often observed. A small number of terminal were that filled mainly by clear flat vesicles (F terminal). The Synaptic relations of the terminals in NYS were mainly axodendritic (95 .5% ). 3.3% of the synaptic contacts were occassionally encountered. A small number of the synapses were synaptic glomeruli. Finally, the morphologic basis of acupuncture analgesia was discussed.
摘要:Analysing from the social background and essential difference between western and Chinese medicine, this paper emphatically discusses various problems faced by TCM in studying and making animal model of“syndrome”in experimental research. It is pointed out that st the present time there is no animal model of“syndrome”which can reflect TCM s specific characteristics and can be accepted widely. The reasons are that there is certain difficulty in making animal model, the relationship between syndrome and formula or herbs is not fixed, and the relationships between syndrome and symptom, physical sign and experimental index are not fixed, too. It is proposed that methodology should be considered in studying TCM. It is also suggested that doubletrack system be applied in the future, i. e. applying experimental research as well as traditional research methods. It would not certainly be benefit to developing TCM if it is continuously persistent to make animal model of“syndromen”nowadays.
摘要:By applying system, information and control theories,this paper discusses the homeostasis viewpoint in Chinese and western medicine, and also comparies the recognition on homeostasis in these two kinds of medical model. It is regarded that“stable yin and consolidated yang”is a high generalization on the homeostasis viewpoint in TCM. The astable yin and consolidated yang“in accordance with time matches prophetic homeostasis. while the “stable yin and consolidated yang”in sudden change belongs to reactive homeostasis. The “spontaneous harmony between yin and yang”is a self-adjusting process to realize“stable yin and consolidated yang”in human body,in which the main adjustment and control mechanism is the feedback control of the five elements.
摘要:Through analysis on ancient medical books and recent decade literature relative to chronic nonspecific ulcerative colitis, it is regarded in this paper that the symptom features of this disease are conformable to that of TCM’s syndrome of arecurrent dysentery“. So its pathological mechanism is summarized as that the spleen deficiency is the“root“damp-heat is the branch”and blood stasis is the local pathological change. In the aspect of treatment,such conclusion is got that the key of treating this disease is to strengthen spleen qi for resolving dampness, to activate blood for resolving stasis and expelling poison,and to reinforce the genuine qi for curing erosion and promoting granulation. It is proposed that treatment of this disease should based on different stages. And it is thought that the future research orientation should be laid emphases on rising cure rate at beginning stage, lowering recurrent rate and strengthening precancerous surveillance.
