作为一种促进生长的饲料添加剂,短链脂肪酸丁酸盐无论是以无保护的形式还是以保护的形式,都在家禽营养中都有广泛的应用,但其对肉鸡胴体组成的影响尚未完全阐明。此外,因为减少氮的排泄具有生态效益,所以降低日粮粗蛋白(CP)水平是家禽养殖中的一个重要问题。本研究的主要目的是测试未受保护和受保护形式的丁酸以及为降低CP含量添加必需氨基酸(赖氨酸、蛋氨酸、苏氨酸、色氨酸)(LP-EAA日粮)的日粮对肉鸡胴体参数和肌肉化学成分的影响。将Ross 308鸡随机分为7组(n=10/组),分别饲喂添加或不添加保护性的丁酸钠同时提供足够的CP(正常蛋白,“NP”)或LP-EAA日粮和添加不同形式保护性丁酸钠的NP日粮,6周龄时测定胴体性状,分析胸肌和股肌的化学成分,LP-EAA日粮和所有保护型丁酸盐均可显著增加胴体重量,而LP-EAA组的相对胸肉产量显著高于NP组,且未加保护和添加保护丁酸的鸡的相对胸肉产量均高于对照组。LP-EAA日粮和各种丁酸盐均可显著降低股肌蛋白质含量,提高其脂质含量。但胸肌的化学成分没有变化。总之,饲料因素可以有效地刺激胸肉的生产,例如通过补充必需氨基酸来降低日粮中的粗蛋白含量,并使用丁酸作为饲料添加剂,而其化学成分与股肌相比保持不变。上述营养策略似乎是提高肉鸡胴体产量和改变肉成分的适当方法,有助于提高家禽肉产量。

义齿修复不仅可恢复牙形态和功能,并且可影响全身健康。牙齿为特殊触感及咬合运动方向感提供了结构基础,使咀嚼和吞咽活动能够有效地进行,同时可感知食物的质地和硬度。颌骨肌外周反馈调节信号主要来自牙釉质-牙本质-牙髓复合体和牙周组织中的机械感受器,来自牙周以及其他口腔部位的机械感受器的信息与来自中枢系统的信息对口腔修复的功能和适应性同等重要。种植体缺乏牙周组织和牙周机械感受器的反馈作用,因而明显降低了对精细咀嚼运动的调节能力,虽然患者依旧可以完成正常的功能活动。种植义齿与全口固定修复治疗相比,在功能恢复程度方面并没有显著差异。种植义齿的预后取决于骨支持情况,理想修复设计的咬合负荷,对种植体周围骨组织改建和骨组织张力有决定性意义。有限元分析结果证实,在种植体上部结构周围(冠状面范围)临床上常见骨吸收的部位,有明显应力集中的情况。牙尖越陡、咬合接触面越宽,应力越集中;面中央窝区域以及咬合接触面越窄的部位,应力集中越不明显。因此建议在设计咬合时应减径,将牙尖交错位作成中央窝承载形式,减小牙尖斜度,以降低功能活动及副功能活动中的侧向力。了解种植修复的这些特点对认识种植修复治疗中的咬合相关问题有重要意义。
