概括

过渡期奶牛的新陈代谢概况因阴道泄漏 (VD) 类型而异. 胎儿,水性VD (VD5) 与其他VD类型相比,显示出明显的血和子宫代谢变化,表明局部子宫变化.

科学领域:

兽医医学兽医医学兽医医学
代谢学代谢学代谢学
乳制品科学乳制品科学

背景情况:

产后子宫健康对于奶牛的生产力至关重要.
阴道泄漏 (VD) 的特征可以表明子宫健康状况.
代谢概况提供了关于过渡期期间生理变化的见解.

研究的目的:

根据产后VD特征,研究过渡期奶牛的血和子宫代谢组差异.
为了将特定的VD类型与系统和局部代谢变化相关联.

主要方法:

从产前,分娩和子宫炎诊断时从奶牛收集的血和子宫洗样本.
使用5分级 (VD1-VD5) 进行分类的VD.
使用非定向气体染色学,飞行时间质谱学 (GC-TOF MS) 和多变量统计分析分析的样本.

主要成果:

在血分娩前或分娩时没有观察到显著的代谢差异 (D0).
在甲状腺炎诊断 (Dx) 时,血代谢组在VD5 (胎儿,水性) 和VD1-VD3 (透明到粘性) 之间有差异,但不是VD4 (性).
在Dx的子宫代谢组在VD5和所有其他VD组 (VD1-VD4) 之间显著不同.

结论:

胎儿,水性静脉疾病 (VD5) 与明显的全身 (血) 代谢变化有关.
性静脉疾病 (VD4) 与较不严重的静脉疾病类型 (VD1-VD3) 具有相似的血代谢特征.
显著的局部 (子宫) 代谢变化主要局限于表现出恶性,水性VD (VD5) 的奶牛.

Surface Membrane Barriers

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Vagina

Vagina

The vaginal canal is a tubular structure averaging about 10 cm in length that acts as the entryway to the female reproductive system and the passageway for menstrual flow and childbirth. The interior walls of the vagina exhibit concentric folds called rugae and are topped by an area known as the fornix, which connects with the protruding cervical portion of the uterus. This canal is comprised of an external fibrous layer, a muscular middle layer, and an inner lining with mucosal rugae, which...
