目的 探讨表皮生长因子(epidermal growth factor,EGF)对小鼠卵母细胞体外成熟及受精的作用.方法 在体外成熟液中分别添加0、0.1、1、5、10ng/Mlegf,12h后检查成熟率,并观察EGF对体外受精的影响.结果 添加5ng/Ml和10ng/Mlegf组卵母细胞第一极体排出率较对照组显著提高(P<0.05),并且5ng/Ml组的效果显著高于其他各组(P<0.05);比较培养液中添加以上浓度EGF对体外受精胚发育的影响,结果发现添加5ng/Ml EGF虽不能显著提高囊胚发育率(P>0.05),但可显著提高其通过二细胞阻滞率和囊胚孵化率(P<0.01).结论 EGF对小鼠卵母细胞体外成熟及受精有促进作用,可提高体外成熟率及囊胚孵化率,还可促进受精卵通过二细胞阻滞.  相似文献

为研究性成熟小鼠生殖泡期(GV)卵母细胞的体外成熟,同时比较体外成熟(IVM)和体内成熟组卵子的受精、胚胎发育情况,机械法分离性成熟小鼠卵巢中的GV期卵母细胞及刺激后的成熟卵母细胞,直接培养于[α-MEM+1 mg/ml Fetuin+10%FCS+1.5 IU/ml rHCG±5 ng/mlrEGF]中,16 h后移入f-HTF+10%FCS体外受精4 h,再在M16+10%FCS中培养72 h。记录其成熟、受精和胚胎发育情况,并与体内成熟的卵子比较。结果:GV期卵母细胞在含HCG培养液中成熟率为89.68%,培养液中添加EGF后,卵子成熟率无显著上升,但受精率、卵裂率均有显著提高(P<0.05)。体内成熟卵子的受精率可达62.83%,卵裂率60.18%;IVM组受精率仅48.92%,卵裂率36.69%,明显低于前者(P<0.01)。结论:小鼠GV期卵母细胞可体外培养成熟、受精和胚胎发育。培养液中添加促性腺激素和EGF都促进卵母细胞体外成熟、受精和胚胎发育能力。但IVM组卵母细胞的受精率、卵裂率低于体内成熟组,培养系统仍需改进。  相似文献

目的:探讨金雀异黄素(Gen)对小鼠卵母细胞成熟的影响.方法:用不同浓度的Gen给小鼠腹腔注射后,检测Gen对卵母细胞生发泡破裂(GVBD)、第一极体(PB1)释放、体外受精和胚胎发育等的影响;用含不同浓度的Gen的培养液培养小鼠未成熟卵母细胞,观察卵母细胞GVBD、PB1释放的发生率;结果:腹腔注射Gen可以增加小鼠子宫湿重,增加小鼠的超排卵数(除高剂量组外)、影响卵母细胞体内成熟过程中的GVBD和第一极体的释放(Gen-0.5组除外),高剂量组小鼠成熟卵母细胞的受精能力和胚胎发育能力均下降.Gen以剂量依赖的方式抑制体外培养小鼠未成熟卵母细胞的GVBD和PB1的释放.结论:Gen能够可逆性地抑制小鼠未成熟卵母细胞的成熟,高剂量的Gen可能影响卵母细胞减数分裂过程,降低卵母细胞的受精能力,提示育龄妇女摄人过量Gen及其化合物可能会导致生育能力降低,甚至造成不育或不孕.  相似文献

CASE HISTORY A female patient, 46 years old, head of the foreign affairs department of a certain university in Beijing, paid her first visit on October 9, 2006, with the chief complaint of vomiting for one month. She got vomiting after meals in early September. Before that, she had discomfortable sensation in the stomach due to angry with others, but she didn't pay much attention. Later, it developed into vomiting after eating. After the vomiting, the discomfort would be relieved, but with slight hypodynamia. She was once diagnosed as having 'neurogenic vomiting'. Having taken some western and Chinese drugs, the above symptoms were a little bit improved, but she would have nausea upon eating and with regurgitation. Because of the fear for vomiting, she did not dare to have food intake, with body weight reduction of 6 kilos in one month.  相似文献

Radiotherapy and chemotherapy are the important modern medical therapies for malignant tumors,yet they can also bring about serious local and systemic toxic side reactions so to decrease the patient;'s life quality,manifested by a series of consumptive symptoms.Having engaged in the combined work of Chinese and western medicine for nearly 50 years,the research fellow Qiu Baoguo in Henan Provincial Academy of TCM has developed his unique views on the TCM study of consumptive syndromes.The author of this essay had once the fortune tO follow Dr.Qiu in clinic,and specially would like to introduce in the following Dr.Qiu's experience in treating consumptive syndromes after radio-chemotherapies for patients with malignant tumor.  相似文献

OBJECTIVE: To observe therapeutic effects of the comprehensive therapy of acupuncture-moxibustion and Chinese Tuina for treatment of insomnia due to deficiency of both the heart and spleen. METHODS: 92 cases were divided randomly into the treatment group (treated by acupuncture-moxibustion and Chinese Tuina) and the control group (treated by acupuncture-moxibustion). RESULTS: The therapeutic effect of the treatment group was obviously superior to that of the control group (the CHI2 test showed P < 0.01). CONCLUSIONS: The comprehensive therapy of acupuncture-moxibustion and Chinese Tuina can give marked therapeutic effects for treatment of insomnia due to deficiency of both the heart and spleen.  相似文献

Evidence obtained from randomized controlled trials (RCTs) has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine (TCM) and results have shown that there is an urgent need for higher quality RCTs on TCM.  相似文献
