Purpose of Study

To provide a detailed protocol for fecal sample collection.
To demonstrate the Swiss-roll method for gut analysis.
To facilitate research on dysbiosis in cardiovascular disease.

Methods Used

Aseptically collect murine fecal samples.
Isolate the gastrointestinal tract, focusing on the cecum.
Employ the Swiss-roll method for tissue analysis.
Utilize immunostaining techniques to observe changes.

Main Results

Successful collection and preservation of fecal samples.
Effective isolation of the cecum for analysis.
Implementation of the Swiss-roll method yielded insightful data.
Immunostaining revealed significant changes in gut morphology.

Conclusions

The outlined protocol is a valuable tool for studying dysbiosis.
Findings contribute to understanding gut health in cardiovascular disease.

Frequently Asked Questions

What is dysbiosis?

Dysbiosis is an imbalance in the microbial communities in the gut, which can affect health.

Why is the Swiss-roll method used?

The Swiss-roll method allows for detailed examination of gut tissue architecture and microbiota interactions.

How are fecal samples collected?

Fecal samples are collected aseptically from euthanized mice to prevent contamination.

What techniques are used for analysis?

Immunostaining techniques are employed to visualize changes in gut tissue.

What are the implications of this research?

Understanding dysbiosis can lead to better therapeutic strategies for cardiovascular diseases.

Can this protocol be applied to other diseases?

Yes, the protocol can be adapted to study dysbiosis in various diseases beyond cardiovascular conditions.

这里的目标是概述一个方案，以研究心血管疾病中生态失调的机制。本文讨论了如何无菌收集和移植鼠粪便样本，分离肠道，并使用"Swiss-roll"方法，然后使用免疫染色技术来询问胃肠道的变化。

在这里，我们描述了一种协议，以指导其他人调查疾病中生态失调的机制，从收集粪便样本到使用瑞士卷法研究肠道变化。首先，用70%乙醇喷洒安乐死小鼠的胸部和侧面，并小心地打开皮肤和腹膜腔以暴露胃肠道。隔离盲肠，并使用无菌手术剪刀将其切成两半。

短暂暴露盲肠，从回肠近端切开 0.5 厘米，在与结肠的连接处远切 0.5 厘米。将分离的盲肠转移到无菌培养皿上。使用无菌刮刀将盲肠内容物转移到无菌管中，并将等分试样储存在 80 摄氏度的冰箱中。
