Abstract
Lobaria pulmonaria, a lichen species, has been used in traditional medicine for the treatment of various diseases. This study was designed to determine the gastroprotective effect of the methanol extract of L. pulmonaria in an indometacin-induced ulcer model in rats. The results showed that gastric lesions were significantly reduced in a dose-dependent manner. Furthermore, the administration of indometacin caused a significant decrease in the levels of superoxide, glutathione peroxidase and reduced glutathione and an increase in the lipid peroxidation level. Administration of the lichen extract, however, produced an increase in the levels of these enzymes and a decrease in lipid peroxidation levels, although catalase and myeloperoxidase levels were unaffected. The present results suggested that Lobaria pulmonaria has a gastroprotective effect, probably due to reducing oxidative stress and neutrophil infiltration.

Anti-inflammatory and antiulcerogenic effects of the aqueous extract of Lobaria pulmonaria (L.) Hoffm.

Abstract
An aqeuous extract of Lobaria pulmonaria (L.) Hoffm., from which a tea is prepared and consumed as treatment for various diseases in northeastern Turkey, was tested for its anti-inflammatory and antiulcerogenic effects in rats. The carrageenan-induced paw edema, cotton pellet granuloma and indomethacin-induced gastric damage models were used to determine these effects. The extract exhibited moderate anti-inflammatory and strong antiulcerogenic activities.
