ABSTRACT
ABSTRACT

Objective:

To observe the effect of thymosin alpha l (Tα1) on severe acute pancreatitis (SAP) in rats.

Methods:

Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups (eight in each group) control group (Group A), SAP group (Group B) and Tα1 treatment group (Group C). Animal models of SAP were made by retrograde injection of 5% sodium taurocholate into the biliopancreatic duct. Rats in Group C were treated with Tα1 (6 mg/kg) via intraperitoneal administration prior to SAP modelling. Eight rats in each group were sacrificed at 12 hours, respectively, after modelling. The serum levels of amylase, tumour necrosis factor-α (TNF-α), interleukin-lβ (IL-lβ and interleukin-6 (IL-6) were detected in each group. The pathological scores of the tissue in the pancreas head were observed by light microscopy.

Results:

The levels of serum amylase of Group B were 6378 ± 538 U/L, which were significantly higher than those (4587 ± 478 U/L) of Group C (p < 0.05). The levels of serum TNF-α of Group B were 360.32 ± 28.67 pg/mL, which were higher than those (269.99 ± 26.11 pg/mL) of Group C (p < 0.05). The levels of serum IL-lβ of Group B were 435.93 ± 36.00 pg/mL, which were higher than those (312.42 ± 17.89 pg/mL) of Group C (p < 0.05). The levels of serum IL-6 of Group B were 433.90 ± 28.36 pg/mL, which were higher than those (289.98 ± 23.00 pg/mL) of Group C (p < 0.05). The pancreatic pathological scores of Group B were 13.34 ± 2.19, which were higher than those (6.39 ± 1.86) of Group C (p < 0.05).

Conclusion:

Thymosin alpha 1 could decrease proinflammatory cytokines and reduce pancreas injury and had a protective effect in rats with SAP. This provides a new strategy for the clinical treatment of SAP.
RESUMEN
RESUMEN

Objetivo:

Observar el efecto de la timosina alfa l (Tα1) sobre la pancreatitis aguda grave (PAG) en ratas.

Métodos:

Veinticuatro ratas Sprague-Dawley adultas machos fueron divididas aleatoriamente en tres grupos (ocho en cada grupo) grupo de control (grupo A), grupo de PAG (grupo B) y grupo de tratamiento con Tα1 (grupo C). Los modelos animales de PAG fueron creados mediante inyección retrógrada de taurocolato de sodio al 5% en el conducto biliopancreático. Las ratas del grupo C se trataron con Tα1 (6 mg/kg) via administración intraperitoneal antes del modelado de PAG. Las ocho ratas en cada grupo fueron sacrificadas a las 12 horas, respectivamente, después del modelado. Los niveles séricos de amilasa, factor-α de necrosis tumoral (TNF-α), interleucina-β (Il-β) e interleucina-6 (IL-6) fueron detectados en cada grupo. Las puntuaciones patológicas del tejido en la cabeza del páncreas fueron observadas mediante microscopía de luz.

Resultados:

Los niveles de amilasa sérica del grupo B fueron 6378 ± 538 U/L, y resultaron significativamente más altos (p < 0.05) que los niveles 4587 ± 478 U/L del grupo C. Los niveles séricos de TNF-α del grupo B fueron 360.32 ± 28.67 pg/mL, y resultaron ser más altos (p < 0.05) que los 269.99 ± 26.11 pg/mL del grupo C. Los niveles séricos de Il-β del grupo B fueron 435.93 ± 36.00 pg/mL, y fueron más altos (p < 0.05) que los 312.42 ± 17.89 pg/mL) del grupo C. Los niveles de suero IL-6 del grupo B fueron 433.90 ± 28.36 pg/mL, y resultaron ser más altos (p < 0.05) que los 289.98 ± 23.00 pg/mL del grupo C. Las puntuaciones patológicas pancreáticas del grupo B fueron 13.34 ± 2.19, y resultaron ser más altas (p < 0.05) que las puntuaciones 6.39 ± 1.86 del grupo C.

Conclusión:

La timosina alfa pudo disminuir las citoquinas proinflamatorias y reducir la lesión del páncreas, y tuvo un efecto protector en las ratas con PAG. Esto ofrece una nueva estrategia para el tratamiento clínico de PAG.
