概括
母亲使用抗生素和围产期窒息 (PA) 对后代的神经发育产生负面影响,并增加神经炎症. 即使是孕期安全的抗生素也会破坏肠道微生物群,加剧PA对小鼠婴儿的影响.
科学领域:
- 神经科学是一个神经科学.
- 微生物学 微生物学
- 发育生物学 发展生物学
背景情况:
- 母亲肠道微生物组的改变与后代的神经发育问题有关,特别是与大脑脆弱性因素,如围产期窒息 (PA).
- 母亲微生物组与胎儿大脑之间的相互作用对于健康的后代神经发育至关重要.
研究的目的:
- 模拟孕期抗生素和PA诱导的孕产妇肠道失生症对后代神经发育的影响.
- 研究不同抗生素治疗方案对母亲健康和后代神经发育的影响.
主要方法:
- 在怀孕期间,Wistar大鼠接受了抗生素,随后在出生后的第6天出现了周围窒息 (PA) 或正常氧.
- 评估了母亲的肠道微生物组合,怀孕结果,后代体重,神经发育反射和海马神经炎症.
- 两种抗生素尾酒被测试:一种导致严重的妊娠并发症,另一种旨在更安全的怀孕.
主要成果:
- 最初的抗生素尾酒增加了流产,减少了母亲的体重增加和后代的体重,并改变了母亲的肠道微生物组.
- 无论是PA还是抗生素暴露,都会损害后代的神经发育反射和增加海马神经炎症.
- 第二种更为安全的抗生素尾酒仍然破坏了母亲的肠道微生物组,PA效应被抗生素管理放大.
结论:
- 孕产妇的失生症和PA对后代的神经发育有累积的有害影响.
- 由于潜在的神经发育影响,建议谨慎使用妊娠期抗微生物药物.
- 需要对长期影响,母亲行为和益生菌干预措施进行进一步的研究.

Anatomy of the Intestines
71.6K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Teratogenicity
2.4K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
