The purpose of the present study was to investigate the mechanism of the effect of estrogen on the production of acetylcholine in the brain and to study the regulatory role of acupuncture of Zusanli acupoint in acetylcholine production in the brain of ovariectomized rats. Experimental female Wistar rats were divided into three groups: intact group (INT), ovariectomized group (OVX), and ovariectomy and acupuncture group (OVX+AC). Radioimmunoassay (RIA) was used to measure the estrogen content in plasma. The mRNA expression of choline-acetyltransferase (ChAT) and glyceraldehyde phosphate dehydrogenase (GAPDH) in the brain of rats was measured by the RT-PCR technique and was tested by the method of agarose gel electrophoresis. The ChAT mRNA positive neurons in the hippocampus were observed by using in situ hybridization and the results were processed with a computerized image analysis system. The results are as follows. Compared with the control animals, the plasma estrogen level was significantly lowered in ovariectomized animals. However, the plasma estrogen level was higher in the OVX+AC group than that of the OVX group. The ChAT mRNA expression level of OVX+AC group was higher than that of the OVX group. The area and integral optical density of the ChAT mRNA positive neurons in the hippocampus increased more obviously in OVX+AC group than in the OVX group. The experimental results observed indicate that the expression of ChAT gene in the brain is possibly related to the estrogen level in the body. The expression of ChAT gene in the brain of the ovarietomized rat can be regulated by acupuncture of Zusanli acupoint and it may be one of the mechanisms that acupuncture increases acetylcholine content in the brain.
OBJECTIVE: To evaluate use of the acupuncture meridian test for detection of recent or recently reactivated equine herpesvirus type 1 (EHV-1) infection in horses with decreased performance. DESIGN: Case-control study. ANIMALS: 40 horses. PROCEDURE: Physical and neurologic examinations were performed, and acupuncture points on the bladder meridian were tested for sensitivity reactions in case and control horses. Polymerase chain reaction assays were performed to determine whether EHV-1 or equine herpesvirus type 4 (EHV-4) DNA could be detected in peripheral blood mononuclear cells. Complement fixation (CF) tests for detection of antibodies against EHV-1 and EHV-4 and virus neutralization (VN) tests for detection of antibodies against EHV-1 were performed on paired serum samples obtained 3 weeks apart. RESULTS: There was a significant difference in skin sensitivity in the cervical, sacral, and gluteal regions and flank between case and control horses. By use of the meridian test, all case horses were sensitive to manipulation of all acupuncture points believed to be associated with EHV infections, whereas only a few control horses were sensitive at an occasional point. Equine herpesvirus type 1 or EHV-4 viremia was not detected in any horses. Mean +/- SDVN antibody titers against EHV-1 were not significantly different between the 2 groups. Mean +/- SD CF antibody titers against EHV-1 obtained 3 weeks after the initial samples were higher in case horses than control horses; however, unequivocal seroconversion was not detected. CONCLUSIONS AND CLINICAL RELEVANCE: Results of the meridian test in case horses were associated with sensitivity reactions similar to those detected by physical and neurologic examinations; however, an unequivocal association with EHV-1 or EHV-4 infection was not detected.
