There were different opinions about whether ketamine has an antagonistic effect on electroacupuncture (EA) analgesia. The aim of this paper was to investigate the effect of ketamine on EA. The rats were divided into three groups: 4 mg/kg, 20 mg/kg of ketamine in doses, and normal saline groups. Ketamine was injected peritoneally in dosage of 4 mg/kg and 20(More)
OBJECTIVE To observe the effect of electroacupuncture (EA) on expression of pain sensory and affective processing-related µ-opioid receptor (MOR), glutamatergic AMPA receptor subunit GIuA 1, extracellular signal-regulated kinase (ERK 1/2), cAMP response element binding protein(CREB) in the amygdala in chronic constrictive injury (CC) + negative(More)
In this paper effect of EA on nociceptive responses after topical application of bicuculline on the cortical somatosensory area of rats was investigated. Changqiang and Yaoshu point were selected for electroacupuncture. The results showed that the effect of EA on tail flick latency elicited by radiant heat and vocalization threshold elicited by electrical(More)

The dynamic changes of cellular immune function and antitumor effect of GTE (green tea extract) in the BALB/c mice bearing EAC, HAC and S-180 tumor were investigated. Results showed that intraperitoneal injection GTE daily dose of 80mg/kg stimulate the proliferation of T-Lymphocyte S-180 tumor bearing mice, the 125-IudR incorporation value (cpm) of control(More)

Green tea extract (GTE) inhibits obviously gastrointestinal malignant tumors in rats induced by N-methyl-N'-nitro-n-nitrosoguanidine (MNNG). The incidence of tumor was 93.3% in the MNNG positive control group, whereas 53.3% in the MNNG plus GTE group (P < 0.01). The percentage of inhibiting tumor growth was 88% (P < 0.001). N-nitrosoproline blockage test in(More)
OBJECTIVE To observe the effect of electroacupuncture .(EA) stimulation of "Zusanli" (ST 36)-"Yang- lingquan" (GB 34) on expression of pain sensory and affection processing-related corticotropin-releasing factor (CRF) receptor, glutamatergic NMDA receptor and GABA receptor subtype genes in the amygdala in chronic constrictive injury (CCI) of the sciatic(More)
It is reported here that the NOR activity of mouse embryonic cells treated with BrdU in Vitro. The NOR activity could be recovered after incubating the cells in the BrdU-free medium. The inhibition of NOR activity in the early and mid-term gestation led to abnormal development as follows: the increase of fetus abortion in vivo and death rate of newborn(More)

We have studied and found antitumor effects in Chinese green tea extracts (T-8750). By pharmacologic test, it showed anticancer actions against several kinds of tumors in NIH mice evidently. Clinical trials on the therapeutics effects against early stomach cancer showed very effective. In order to prove it's function to prevent cancer. The research results(More)
