Abstract

Background: Reindeer lichen, Lichen rangiferinus syn. or Cladonia rangiferina (L.) F. H. Wigg. (Cladoniaceae) has been traditionally reported as a remedy to treat fever, colds, arthritis as well as convulsions, liver infections, coughs, constipation, and tuberculosis. The current study is aimed at rectification of alcohol induced liver damage by the use of L. rangiferinus extract.

Objectives: The aim of the study was to compare some biochemical markers for liver injury and hematological indices in normal untreated rats and treated rats.

Material and methods: The study was performed using male Wistar rats. Animals were categorized into five groups, negative control group (normal diet only), treated groups (2 groups were lichen treated along with 10% ethanol & 1 group was only ethanol treated) and positive control group (Silymarin+10% ethanol) of six animals in each group. Biochemical markers for liver injury and hematological indices of all animals were measured using standard diagnostic tools. The animals were then sacrificed and livers were sent to the pathology lab for histopathological analysis.

Results: Lichen extract showed a significant restoration of altered biochemical parameters towards normal in both in vitro and in vivo conditions. The total phenolic and flavonoid content of the LRE was found to be 21.78 μg PE/mg of extract and 5.13 μg RE/mg of extract respectively. The IC50 values for atranorin and fumarprotocetraric acid were found to be 128.48 and 218.46 mg/mL respectively. Reducing power of the extract was found to be quite significant. After administration of lichen extract, endothelial cells were less injured around central vein and number of fat vacuoles was also lesser in hepatocytes.

Conclusion: Conclusively, treatment with lichen extract assuages alcohol-related damage and guards hepatic tissue from alcohol-induced toxicity.
