[Correction of bioenergetic processes in small intestine during experimental widespread purulent peritonitis]
Abstract:
The functional activity of mitochondria of the muscular coat of small intestine (MCSI) has been studied in the normal state and under experimental widespread purulent peritonitis (WPP) conditions. The experiments have been carried out on a group of 55 male rabbits of chinchilla breed. It is established that, as a result of the WPP development, the functional activity of mitochondria in MCSI considerably decreases. The comparative analysis of the efficiency of metabolic drugs cytoflavin and neoton showed advantage of the citoflavin preparation, the administration of which allowed the indices of mitochondria in intact animals to be exceeded on the fifth day of postoperative period. The research results show expediency of a complex treatment of WPP using cytoflavin preparation for the normalization of biological oxidation processes and elimination of enteric insufficiency.
Insights
Widespread purulent peritonitis (WPP) impairs mitochondrial function in the small intestine. Cytoflavin treatment effectively restored mitochondrial activity, exceeding normal levels and aiding recovery from enteric insufficiency.
Area of Science:
- Mitochondrial physiology
- Gastroenterology
- Experimental surgery
Background:
- Mitochondrial dysfunction is a key factor in organ damage during sepsis.
- Small intestine integrity is crucial for preventing systemic complications in peritonitis.
Purpose of the Study:
- To investigate the impact of widespread purulent peritonitis (WPP) on mitochondrial function in the small intestine's muscular coat (MCSI).
- To compare the efficacy of metabolic drugs cytoflavin and neoton in mitigating WPP-induced mitochondrial damage.
- To evaluate the potential of cytoflavin in normalizing biological oxidation and resolving enteric insufficiency.
Main Methods:
- Experimental induction of WPP in 55 male chinchilla rabbits.
- Assessment of mitochondrial functional activity in MCSI samples.
- Comparative analysis of cytoflavin and neoton administration post-WPP.
Main Results:
- WPP significantly decreased the functional activity of MCSI mitochondria.
- Cytoflavin demonstrated superior efficacy compared to neoton.
- Cytoflavin administration led to mitochondrial indices exceeding those of intact animals by day five post-surgery.
Conclusions:
- WPP severely compromises mitochondrial function in the small intestine.
- Cytoflavin is an effective therapeutic agent for WPP, promoting mitochondrial recovery.
- The use of cytoflavin in complex WPP treatment is recommended for restoring metabolic processes and addressing enteric insufficiency.

Mechanical and Chemical Digestion in the Small Intestine
Mechanical digestion in the small intestine involves movements such as segmentations and migrating motility complexes (MMCs), primarily controlled by the myenteric plexus. Segmentations are localized contractions occurring in areas of the intestine distended by chyme—a mixture of partially digested food. These contractions mix chyme with digestive juices, facilitating absorption...
