Summary

This summary is machine-generated.

Resveratrol (RES) and beta-carotene (βC) show protective effects against acute pancreatitis (AP) in rats. These compounds reduce oxidative stress, inflammation, and apoptosis, with RES exhibiting slightly superior efficacy.

Area Of Science

  • Biochemistry
  • Pharmacology
  • Cell Biology

Background

  • Acute pancreatitis (AP) is a severe pancreatic inflammation with systemic effects.
  • Oxidative stress, inflammation, and apoptosis are key pathological mechanisms in AP.
  • L-arginine is a common agent used to induce experimental AP models.

Purpose Of The Study

  • To evaluate the therapeutic effects of resveratrol (RES) and beta-carotene (βC) on L-arginine-induced acute pancreatitis in a rat model.
  • To investigate the impact of RES and βC on oxidative stress, pancreatic islet integrity, inflammatory markers, and apoptotic pathways in AP.

Main Methods

  • Establishment of an L-arginine-induced acute pancreatitis model in Sprague Dawley rats.
  • Administration of resveratrol (20 mg/kg) and beta-carotene (50 mg/kg) to separate treatment groups.
  • Assessment of oxidative stress markers (MDA, GSH), pancreatic islet morphology (immunohistochemistry), inflammatory gene expression (qPCR), and apoptotic markers (qPCR).

Main Results

  • L-arginine-induced AP significantly increased oxidative stress (elevated MDA, reduced GSH) and pancreatic inflammation (upregulated NF-κB, TNF-α, IL-1β).
  • AP led to reduced Langerhans islet size and altered apoptotic gene expression (increased Bax, Caspase-3; decreased Bcl-2).
  • Both RES and βC treatments significantly ameliorated oxidative stress, preserved islet morphology, suppressed inflammatory gene expression, and modulated apoptotic pathways. RES showed a slightly greater effect.

Conclusions

  • Resveratrol and beta-carotene demonstrate significant protective effects against L-arginine-induced acute pancreatitis in rats.
  • These compounds mitigate AP by reducing oxidative stress, preserving pancreatic islet integrity, suppressing inflammation, and modulating apoptosis.
  • Resveratrol may offer a slightly more potent therapeutic benefit for acute pancreatitis compared to beta-carotene.
