쥐에서 쇄골하 천자를 통한 심장 혈액 수집

Overview

This study evaluates the efficacy of subclavian cardiac puncture as a method for collecting terminal blood in mice. Utilizing this technique improves sample purity and reliability compared to traditional blood collection methods, minimizing risks to the organism.

Key Study Components

Research Area

• Cardiac blood collection
• Mice as a model organism
• Ethical considerations in animal research

Background

• Blood sampling is crucial in scientific research involving mice.
• Traditional methods have ethical limitations and risks.
• The subclavian puncture method minimizes these concerns.

Methods Used

• Subclavian puncture technique for blood collection
• Mice (C57BL/6 strain) weighing between 21 and 29 grams
• Use of heparin-coated microcentrifuge tubes for plasma transfer

Main Results

• Blood volumes collected ranged from 700 to 1,200 microliters.
• Sample purity was maintained, avoiding contamination.
• No significant gender differences in results for ALT and AST levels.

Conclusions

• Subclavian cardiac puncture is effective for high-purity blood collection in mice.
• This method is vital for accurate experimental data and reduces animal stress responses.
