    • 摘要: 目的:探讨不同剂量的植物雌激素三羟异黄酮(GST)对子宫质量及内膜的影响。方法选取50只成熟雌性SD大鼠,随机分为5组:假手术组、去卵巢组、去卵巢+GST低剂量组(25mg/kg)、去卵巢+GST中剂量组(50mg/kg)、去卵巢+GST高剂量组(100mg/kg),后3组每天以不同剂量GST溶液灌胃,实验持续4周。结果实验结束时,各组大鼠体质量较实验前均有增加,差异均有统计学意义(均P<0.05),但组间比较差异无统计学意义(P>0.05);GST低、中、高剂量组子宫质量分别为(0.18±0.03)、(0.16±0.04)、(0.17±0.05)g;对应的子宫质量/体质量分别为0.64±0.05、0.53±0.08、0.58±0.03,3组间的差异无统计学意义(P>0.05);分别与去卵巢组比较[子宫质量(0.15±0.05)g、子宫质量/体质量0.48±0.08],差异均无统计学意义(均P>0.05);但与假手术组比较[子宫质量(0.45±0.08)g、子宫质量/体质量3.45±0.25],差异均有统计学意义(均P<0.01)。显微镜下观察大鼠子宫内膜,去卵巢组子宫内膜腺体小而稀少,使用不同剂量GST的低、中及高剂量组子宫内膜仍与去卵巢组一样,分布不均匀,腺体内衬上皮由立方或扁平细胞组成,明显富于细胞。结论不同剂量GST均不会促进去势大鼠子宫质量增加及子宫内膜增生,在临床应用可能是安全的。%Objective To investigate the effect of different doses of genistein (GST)on uterus and endometrium in o-variectomized rats. Methods Forty female SD rats received ovariectomy and 10 rats received sham operation (normal control). The ovariectomized rats were further divided into 4 groups (10 in each):rats in low- dose, middle- dose and high- dose groups were fed with 25mg/kg·d, 50mg/kg·d and 100mg/kg·d GST, respectively; rats in overiectomized control group were fed with same volume of DMSO as those in normal control group. After 4 weeks, the animals were sacrificed, and uterus specimens were obtained. The ratio of weights of the uterine over body was calculated and histopathological examinations on the uterus were performed. Results After 4 weeks, body weights were increased in al groups, and there was no significant difference(P>0.05) among 5 groups. The weights of uterus in low, middle, high GST groups and overiectomized control group were 0.18±0.03g, 0.16±0.04g, 0.17±0.05g and 0.15±0.05g, respectively (P>0.05), and the uterine/body weight ratio was 0.64±0.05, 0.53± 0.08, 0.58±0.03 and 0.48±0.08, respectively (P>0.05). There were significant differences in uterus weight and uterus/body weight ratio between GST groups and normal control group (P<0.01). The histopathology showed that uterus from ovariec-tomized group and GST groups had smal er endometrial glands than those from normal rats, and there was uneven distribution of glands and the glands were lined by cuboidal or squamous epithelial cells. Conclusion Different doses of GST have no sig-nificant effect on uterus enlarging and endometrial hyperplasia in ovariectomized rats, suggesting that GST administration might be safe in clinical application.

    • 摘要: OBJECTIVE: To investigate the protective effects of genistein on apoptosis of rat cerebellar granule neurons induced by acrylamide. METHODS: Rat cerebellar granule neurons were prepared from the cerebellar cortex cells of 5-7day-old SD rats pups. The neurons were identified by Nissl staining method.The 8-day cultured cells passage were divided randomly into control group, acrylamide model group, genistein pretreatment group Ⅰ ,Ⅱ , Ⅲ (cerebellar granule neurons were pretreated with 10,25,50 μ mol/L genistein for 12 hours,the culture medium discarded and fresh DMEM/F12 solution added with the above mentioned concentration of genistein with 10 mmol/L acrylamide tocultured neurons for 24 hours). The neuronal viability was measured by MTT. Morphology of neurons and their nuclei were examined by phase-contrast and Hochest33342 staining,respectively. The ratio of apoptotic cells was detected by TUNEL.RESULTS: The cell survival rates of genistein pretreatment group Ⅱ and Ⅲ were not significantly higher than acrylamide model group. Genistein pretreatment group Ⅰ significantly prolonged the cell survival rate. The effects of diminished neuronal body, chromatin concentration and the ratio of apoptotic cells induced by acrylamide were markedly weakened.CONCLUSION: Genistein did not show a dose-dependent effect on protection. The appropriate concentration of 10 μ mol/L was found to protect against apoptosis induced by acrylamide in primary culture of cerebellar granule neurons.%目的:探讨三羟异黄酮(genistein,GEN)对丙烯酰胺(acrylamide,ACR)诱导的大鼠小脑颗粒神经元凋亡的保护作用.方法:取新生5~7 d的SD大鼠小脑皮质细胞进行培养,采用尼氏染色法鉴定神经元,将培养8 d的神经元随机分成5组:正常对照组、ACR染毒组(浓度为10mmol/L)以及CEN不同浓度保护组(染毒前分别用浓度为10、25、50μmol/L的GEN预先处理细胞12h,再给予ACR染毒24 h).MTT法检测细胞存活率;相差显微镜及Hoechst33342染色观察细胞及其细胞核形态学变化;TUNEL法检测神经元凋亡率.结果:GEN 25、50μmol/L保护组的细胞存活率与ACR染毒组比较差异无统计学意义(P>0.05);仅GEN 10μmol/L浓度保护组能明显提高神经元存活率,减少神经元胞体皱缩、细胞核同缩等特征,降低神经元凋亡率.结论:一定浓度的GEN(10μmol/L)能够保护ACR所致的大鼠小脑颗粒神经元凋亡,但GEN对神经元的保护作用并不随剂量增加而增强.
