METHODS: Newborn rabbits with hyperbilirubinemia were decapitated and then, Na~+-K~+-ATPase activities, neurotransmitters and non-neurotransmitters concentration in brains were determined. RESULTS: It was found that the activities of Na~+-K~+-ATPase both in brains and cytomembrane and the amounts of glutamate (P
6.THE EFFECT OF HIGH-DOSE ESTRADIOL ON THE THYMUS OF THE RATS——A HISTOLOGICAL STUDY
Acta Anatomica Sinica 1953;0(01):-
Rapid involution of the thymus was induced in SD rats after administration of high-dose estradiol benzoate. The prominent histological changes observed were as follows: (1) the thymic cortex was become thinner; (2) the corticomedullary ratio was decreased; and (3) a substantial loss of cortical lymphocytes occurred. As a consequence, marked reduction in thymus weight was caused. Under electron microscope, the epithelial reticular cells (ERCs) were found, to be a heterogenous cell group. Their responses to high-dose estradiol were different from each other, and the distinctive changes observed were: (1) cell degeneration changes in some pale ERCs were observed; (2) the other pale ERCs were found to be filled with lower density vacuoles which were very similar to secretory vacuoles; and (3) the dark ERCs were inereased obviously, and many collagen fibril bundles were seen in the vicinity of their perikarya or wrapped by their cytoplasmic processes. There were no striking ultrastructural changes in thymocytes. However, the number of ANAE positive cells in the experimental group was lower than that of the controls evidently. In addition, a large number of plasma cells were observed in the cortex of the experimental group. Based on the above mentioned observations, the possible mechanism of the estradiol effect on the thymus involution was discussed.
7.Effects of Suanzaoren Decoction on Learning and Memory Ability and Brain Neurotransmitters Content of Senile Insomnia Model Rats
China Pharmacy 2016;27(22):3085-3087
OBJECTIVE:To study the effects of Suanzaoren decoction on learning and memory ability and brain neurotransmit-ters content of senile insomnia model rats. METHODS:Rats were randomly divided into normal group,model group,positive group [Estazolam tablet,2 × 10-3 g/(kg·d)] and Suanzaoren decoction low-dose,middle-dose and high-dose groups [5,10,15 g/(kg·d)],with 10 rats in each group. Except for normal group,those groups were given D-galactose ih on the back+sleep depriva-tion to induce senile insomnia model. 6 weeks after modeling,treatment groups were given relevant medicine intragastrically for one week,and normal group and model group were given normal saline intragastrically. The escape latency,the percentage of swimming time and the time of original platform crossing were observed,and the contents of Glu and GABA in cerebral tissue were determined as well as the contents of IL-1β and 5-HT in hypothalamus. RESULTS:Compared with normal group,escape la-tency of rats prolonged and the contents of IL-1β and 5-HT in hypothalamus decreased,while the percentage of swimming time of original platform quadirant,the time of original platform crossing and the contents of Glu and GABA in cerebral tissue increased (P<0.05). Compared with model group,above index of treatment groups improved significantly,with statistical significance(P<0.05). Compared with positive group,the changes of above index were more significant in Suanzaoren decoction middle-dose and high-dose groups,with statistical significance (P<0.05). CONCLUSIONS:Suanzaoren decoction could markedly enhance the learning and memory ability of senile insomnia model rats,and reduce neurotransmitters content and relieve the delayed neuronal damage which led by Glu and GABA.
8.Comparison of therapeutic effects on fibromyalgia syndrome between dermal-neurological electric stimulation and electric acupuncture
Chinese Journal of Tissue Engineering Research 2005;9(46):171-173
BACKGROUND: Fibromyalgia is a kind of non-articular rheumatism,manifested as pain and stiffness in various parts of body, associated with sleep disturbance, fatigue, etc. But, the therapeutic effects of common therapies are not satisfactory.OBJECTIVE: To compare dermal neurological electric stimulation and electric acupuncture with routine medication and explore the therapeutic effects on fibromyalgia syndrome (FS).DESIGN: Randomized controlled experiment was designed, in which the patients were taken as the objects in observation.SETTING: First and Third Hospital Affiliated to Xinxiang Medical College.PARTICIPANTS: Totally 66 cases of FS were selected in Clinic of Rehabilitation Center of the First Affiliated Hospital of Xinxiang Medical College from July 1994 to May 2002, all of which were the followed-up cases.They were randomized as dermal-neurological eleetric stimulation group (DE group), electric acupuncture group (EA group) and medical group, 22cases in each one. The patients were aged varied from42 to 55 years and sick in range from 7 to 13 months.METHODS: ① DE group: FZ-1 low-frequency pulsating apparatus was used. Two pairs of electrodes were attached to two pairs of main points that were near to the most distinct pain points and another pair was attached to 1 pair of supplementary points. Continuous wave was selected, pulsating width was 6-150 ms, high frequency 100 Hz and 15 minutes later,changed to low frequency 2 Hz, for another 15 minutes, intensity about (14±3) mA, once/d, continuously for 20 days as one session, totally 2 sessions were required. 4-day rest was demanded between two sessions. ② EA group: No.28 filiform needle was used to be inserted on the points deeply,after qi arrival; G-6805 electric apparatus was applied on the points. Point selection, operation and time 9f treatment were same as DE group. ③ Medical group: Oryzanol and Vit B1 were administrated orally, 30 mg/tablet,3 times a day. Amitriptyline was administrated, 10 mg every day at beginning, increased by 10 mg every day till to 20-30 mg. It was taken orally once before sleep, totally for 45 days.MAIN OUTCOME MEASURES: ① Comparison of therapeutic effects on analgesia in each group. ② Comparisons of follow-up visits of cured cases and cases with remarkable effects in 6, 12 and 24 months after treatment.RESULTS: Totally 66 cases all entered the result analysis. ① Comparison of total effective rate of analgesia: The rates in DE group and EA group were higher significantly than medical group (100% ,95.5% ,68.2%;X2=18.03,17.27,P < 0.01). ② Comparison of recurrence rate: The rates in DE group and EA group in 24 months after treatment were lower remarkably than medical group (7.1%,6.1%,50.0%;X2=7.01,6.91 ;P < 0.05). CONCLUSION: Both dermal electric stimulation and electric acupuncture present strong analgesia and low recurrence rate. Dermal neurological electric stimulation on acupoints is a kind of non-traumatic method in treatment of fibromyalgia syndrome.
9.Extraction method of the magnetoencephalography somatosensory evoked signals based on the MP decomposition
China Medical Equipment 2014;(5):48-51
Objective:Matching pursuit algorithm(MAP),for its good parametric characterization, is applied in Magnetoencephalography(MEG) to study time-frequency distribution. Methods:This paper proposes to apply a high-resolution time-frequency analysis algorithm, the matching pursuit (MP), to extract detailed time-frequency components of SEF signals. Results: Experimental results on cortical SEF signals of several normal subjects show that a series of stable SEF time components can be identified using the MP decomposition algorithm. Conclusion:This study shows that there is a set of stable and minute time-frequency componentsin SEF signals, which are revealed by the MP decomposition. These stable SEF components have specific localizations in the time domain and may provide a reliable index for clinical research of brain function and brain disease pathogenesis.
