卵巢切除

METHODS: Ovariectomized rats, with or without estrogen replacement,were anesthetized and hypogastric nerve and abdominal musclecontraction reflex responses to graded uterine cervical distensionwere recorded.

选择卵巢切除的大鼠，给予或不给予雌激素，麻醉后记录不同等级的宫颈扩张时腹壁下神经和腹部肌肉对刺激的的反应。

Considering the merits of in vivo studies in biotransformation i. e. activation or inactivation, protein-binding such as sex hormone binding protein , toxicokinetics, and more evaluative in hazard identification and risk assessment, we selected a battery of short-term and long-term in vivo studies, including uterotrophic assay in weaning mice and ovariectomized adult mice, an in vivo multiple endpoints assay, and a gestational and lactational exposure assay to identify the estrogenic effects of endosulfan on the offspring.

考虑到体内试验在代谢转化、血浆蛋白如性激素结合蛋白的结合、代谢动力学等方面比体外试验优越，在危害鉴定和危险度评定中更有价值，我们选择了多项体内试验，包括对幼年小鼠和卵巢切除成年小鼠的子宫增殖作用、对成年去势小鼠的体内多终点观察以及大鼠孕期和哺乳期接触对雄性子代生殖系统结构和功能的改变，即去雄性化或雌性化作用等，来验证硫丹的体内雌激素样作用。

Objective To observe the distribution of blood vessels in tibial metaphysis in ovariectomized and control mice by micro-CT,and investigate the relationship between bone regional blood supply and osteoporosis.

目的应用显微CT观察卵巢切除小鼠和对照组小鼠的胫骨干骺端血管分布，探讨骨质疏松与骨组织局部血液供应的关系。

Objective To explore the expression of brain-derived neurotrophic factor in the hippocampus after ovariectomy in mice.

目的：探讨小鼠卵巢切除后的不同时期脑源性神经营养因子在海马表达的变化。

Some female dogs may develop varying degrees of urinary incontinence after ovariohysterectomy.

有些雌性犬只在进行子宫卵巢切除术后，可能会发生不同程度的小便失禁。

Early-age neutering refers to castration or ovariohysterectomy before sexual maturity.

早期绝育指在性成熟之前进行的阉割或子宫卵巢切除术。

The distribution of UEA-1 receptors in pseudopregnant rabbit uterus was similar to that of normal pregnant rabbit uterus.

注射雌激素可明显促进卵巢切除后兔子宫内膜UEA-1受体的表达，而注射孕酮对其表达有明显抑制作用。

Fifty rats in the model group underwent ovariectomy, while the other 20 rats in the control group had sham operations. Three months later, 10 rats in the model group and 10 rats in the control group were selected randomly to detect their body weight, uterus weight, BMD of the left femur and lumbar vertebra, biomechanical characteristics of the left femur, levels of serum Ca2 +, Cr, ALP, SOD, MDA and GSH-Px and serumal resistance to OH(superscript -).

4个月龄雌性SD大鼠70只，随机取50只行双侧卵巢切除术，20只行假手术。3个月后随机从手术组和假手术组各取10只大鼠检测体质量、子宫湿重、左侧股骨及腰椎骨密度、生物力学特性和血清生化指标Ca(上标 2+)、肌肝、碱性磷酸酶水平，以确定骨质疏松模型建立成功。

Results: The activities of ALP and ACP, except ACP in the sixth month significantly decreased in the group of thyroidism comparing with that of the control group (P＜0.01), but only the activities of ALP significantly decreased in groups of ovariectomy and diabetes (P＜0.05, P＜0.01), and there was close relationship between enzyme activities and histopathologic variations.

结果：甲状腺素组除6个月组ACP活性较高外，ALP与ACP活性均较对照组低，有统计学差异(P＜0.01)；糖尿病组和卵巢切除组仅ALP降低有统计学差异(P＜0.05或P＜0.01)，酶的活性与骨形态结构变化相吻合。

The tibiae of the rats were kept for the samples of decalcification, IGF-1 in bone tissue was measured by immunohistochemistry and Enzyme linked-immuno-sorbent assay was used to detect the TGF- P 1, IL-6, IL-1 P and TNF- a in serum.

结果 成骨细胞呈线状排列于骨小梁的边缘，细胞因子IGF-1表达于成骨细胞胞浆，骨细胞、软骨细胞及骨基质中也存在IGF-1。不同部位的成骨细胞IGF-1的表达量并不一致，卵巢切除及PTH注射对不同部位成骨细胞IGF-1表达的影响也不一样。
