下面的实验确定了雌激素对食物摄入的抑制是否依赖于下丘脑室旁核(PVN)神经元内蛋白质合成的变化。卵巢切除大鼠在PVN中使用填充有茴香霉素或空(对照)插管进行集中处理。雌性动物注射2.0 μg苯甲酸雌二醇(EB)或油溶剂,2 h后取出内插管。EB注射显著降低了中央对照组的食物和水摄入量,但在PVN植入茴香霉素的动物中没有。所有雌性动物的体重增量均降低。EB在两组中诱导了相当水平的女性性行为,表明茴香霉素植入物不影响雌二醇刺激脊柱前凸的能力。这些发现表明,雌二醇对食物摄入的影响需要激活雌激素敏感的PVN神经元的蛋白质合成。
The following experiment determined whether the estrogenic suppression of food intake is dependent upon changes in protein synthesis within neurons of the paraventricular nucleus of the hypothalamus (PVN). Ovariectomized rats were treated centrally with anisomycin-filled or empty (control) cannulae in the PVN. Females were injected with either 2.0 μg of estradiol benzoate (EB) or the oil vehicle and the inner cannulae were removed 2 h later. EB injections significantly lowered food and water intake in the central control group but not in animals given PVN implants of anisomycin. Body weight gain decreased for all females. EB induced comparable levels of female sexual behavior in both groups, demonstrating that anisomycin implants did not affect the ability of estradiol to stimulate lordosis. These findings indicate that the effects of estradiol on food intake require the activation of protein synthesis in estrogen-sensitive PVN neurons.
