Change in the chemical-induced swallowing reflex in rats due to pharyngolaryngeal injury

Key Points

• This research aims to understand how pharyngolaryngeal injury affects the chemical-induced swallowing reflex in rats.
• Rats underwent pharyngolaryngeal injury to assess changes in swallowing.
• Assessment of swallowing reflex was measured using chemical induction.
• The study involved experimental techniques over a specified duration.
• Significant changes in the swallowing reflex were observed post-injury, indicating altered sensitivity.
• Chemical induction led to decreased reflex efficacy in the injured group compared to controls.
• Statistical analysis showed a strong correlation between injury severity and swallowing reflex changes.
