- 动物营养 动物营养
- 矿物质的新陈代谢.
背景情况:
- 子具有hypselodont (不断生长的) 牙,需要不断更换损失的牙组织.
- 假设这种连续的牙生长需要大量的食矿物质摄入量,特别是.
- 从摄入的,磨损的牙组织中回收的潜力以前没有被研究过.
研究的目的:
- 研究子从摄入的牙组织中回收的能力.
- 为了比较标准源与磨牙对子代谢的影响.
主要方法:
- 采用交叉研究设计,对八个月大的完整雌性子进行了研究.
- 子被以颗粒式饮食,使用对照源 (碳酸/二酸) 或磨牙养15天.
- 测量了摄入量,尿液和便分泌量以及血液矿物质水平.
主要成果:
- 当子食用牙饭饮食时,与对照组相比,的消化能力显著提高 (33 ± 6%),而不是 (20 ± 8%).
- 与对照组 (0.10 ±0.13 g/d) 相比,食牙饮食 (0.33 ±0.10 g/d) 的子的总保持量也显著增加.
- 在治疗组之间观察到的其他显著差异很少.
结论:
- 子表现出一种显著的能力,即从它们磨损的牙组织中回收.
- 这些发现挑战了对子牙生长的高食需求的假设.

01:31Essential Minerals for Bone Health
3.8K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
