RESUMO

OBJECTIVE@#To investigate the effects of acupuncture on ovary morphology and function in dehydroepiandrosterone (DHEA)-induced polycystic ovary syndrome (PCOS) model rats.@*METHODS@#A total of 40 adult female Wistar rats were randomly allocated to 4 groups by a random number table, including control, model, metformin and acupuncture groups, 10 rats in each group. PCOS rat model was developed by injecting with DHEA (6 mg/100 g body weight) in 0.2 mL of oil subcutaneously. Electrical stimulation (2 Hz, 3 mA) was applied to Guanyuan (CV 4), Zigong (EX-CA1) and Qihai (CV 6) acupoints for 30 min daily in the acupuncture group, and metformin (200 mg/kg) was given to rats in the metformin group, both once per day for 21 consecutive days, and rats in the normal group was fed with normal saline and fed regularly. After 21 days of administration, the rat blood samples were collected for detecting the reproductive hormonal levels [luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol (E@*RESULTS@#Compared with the model group, rats in the acupuncture and metformin groups were significantly lower in weight gain, FSH, LH and T levels, and E@*CONCLUSION@#Acupuncture might improve ovary morphology and its function in DHEA-induced PCOS model rats.

RESUMO

<p><b>OBJECTIVE</b>To observe the evolutionary tendency of brain derived neurotrophic factor (BDNF) of the limbic system in post-stroke model rats and the intervention effect of Yinao Jieyu Recipe (YJR).</p><p><b>METHODS</b>Male Wistar rats were randomly divided into the normal control group (n =6), the sham-operation group (n =7), the multiple cerebral infarction (MCI) group (n =10), the post-stroke depression (PSD) group (n =10), the Chinese medicine (CM) treatment group (n =10), and the Western medicine (WM) treatment group (n =10) according to random digit table after open-field testing. Rats in the normal control group were routinely fed. 0. 3 mL normal saline was intravenously pushing from the external carotid artery to rats in the sham-operation group, and distilled water administered to them by gastrogavage. Each dose allogenic microthrombi were in vitro pushed to rats in the rest groups from the external carotid artery. The PSD model was duplicated by 21-day chronic unpredictable mild stress (CUMS) and single cage feeding in the PSD group 7 days after surgery. After preparing models rats in the CM group and the WM group were administered with YJR and Nimodipine respectively for 4 successive weeks. Changes of BDNF and the intervention effect of YJR were observed at week 1, 2, and 4 after intervention.</p><p><b>RESULTS</b>Immunohistochemical results of BDNF showed, compared with the normal control group, expression levels of BDNF in the hippocampus, hypothalamus, and amygdala decreased in the MCI group at week 2 and 4 (P <0. 01 , P <0. 05) ; expression levels of BDNF in each part decreased in the PSD group at week 1-4 (P <0.01). Compared with the MCI group, expression levels of BDNF in each part decreased in the PSD group at week 1-4 (P <0. 01). Compared with the PSD group, expression levels of BDNF in each part increased in the CM group at week 1-4 (P <0. 01).</p><p><b>CONCLUSION</b>BDNF changes existed in post-stroke model rats, and YJR could slow down this progress.</p>
