The aim of the study was to investigate the effects of four Aronia melanocarpa-based juices in a rat model of indomethacin-induced gastric ulceration. The juices were: AM1 and AM2 (produced from aronia fruits at 20 degrees C and 60 degrees C, respectively), AMRC (a mixture of AM2 with Rosa canina extract) and AMAV (aronia juice with Alchemilla vulgaris). Male Wistar rats were used. Each of the juices (10 ml/kg) was administered for 10 days. Indomethacin (30 mg/kg) was injected subcutaneously and after 4 h, the effects were estimated. Indomethacin caused heavy destructions of the gastric mucosa, increased the expression of Bax and decreased the expression of Bcl-2, induced a certain increase in lipid peroxidation and a slight decrease in gastric PGE2 content. The pretreatment with the juices reduced the severity of indomethacin-induced gastric lesions and antagonized the effects of indomethacin on apoptosis and lipid peroxidation. The highest was the protective effect of AMAV, the juice with the highest polyphenolic content. The protective effect of Aronia melanocarpa-based juices against indomethacin-induced gastric lesions could be attributed to their polyphenolic contents. The mechanism involved to the highest extent in the protective effect of the juices was the inhibition of apoptosis.
