Abstract
Channa striata (Bloch.) is a fresh water fish belonging to the family Channidae. The stripped snakehead fish possesses wide range of medicinal properties. In view of traditional use of C. striata for wound healing, the present study was undertaken to investigate the beneficial effects of orally administered freeze dried aqueous extract of Channa striata (AECS) in experimentally induced gastric ulcers in Wistar rats. Aspirin induced ulcerogenesis in pyloric ligation model was used for the assessment of antiulcer activity and Ranitidine (50 mg/kg) was employed as the standard drug. The various gastric parameters like volume of gastric juice, pH, free and total acidities, ulcer index, and levels of antioxidant enzymes like catalase, superoxide dismutase, and lipid peroxidation marker malondialdehyde were determined. AECS at concentrations of 40% and 50% w/v significantly decreased the volume of gastric juice and increased the levels of catalase while considerable decrease in free and total acidities and increase in superoxide dismutase were observed with the treatment of standard drug and AECS (50% w/v). All the test doses of AECS markedly decreased ulcer index and malondialdehyde compared to the standard drug whereas AECS 30% w/v did not alter volume of gastric juice, pH, free and total acidities, catalase, and superoxide dismutase. From these findings, it can be concluded that AECS is devoid of acid neutralizing effects at lower doses and possesses antisecretory and antiulcer activities and this could be related to its antioxidant mechanism.
Highlights
Channa striata (Bloch.) is commonly known as stripped snakehead fish and Haruan in Malay
There are all together 30 species in the family reported around the world and eight of them are found in Malaysia
C. striata contains all the essential amino and fatty acids required for wound healing [3, 4]; the fatty acid content of this fish is rich in arachidonic acid (ARA) [5]
Summary
Channa striata (Bloch.) is commonly known as stripped snakehead fish and Haruan in Malay. It is a tropical and air breathing carnivorous freshwater fish from the family Channidae. There are all together 30 species in the family reported around the world and eight of them are found in Malaysia. C. striata is wild species found in small rivers, lakes, pools, and shallow water bodies and in its natural habitat. It can survive in harsh environments with low dissolved oxygen and high ammonia [2]. Mohd Shafri and Mat Jais reviewed in detail the description, habitat, traditional
