Impact of Whole Plant Extract of Pergularia daemia on Glycoproteins in Dimethylbenz(A)Anthracene Induced Hamster Buccal Pouch Carcinogenesis

Background: Oral squamous cell carcinoma is a major component of a diverse group of neoplasms often referred to as ‘head and neck cancer’. Frequent smoking and/or alcohol consumption are two major risk factors for oral cancer. Objectives: The present study was aimed to investigate the protective role of Pergularia daemia ethyl acetate and methanolic extracts (PDEAE and PDME, respectively) on glycoproteins in dimethylbenz(a) anthracene (DMBA) induced hamster buccal pouch carcinogenesis. Materials and Methods: Male golden Syrian hamsters were used and divided into six groups. Group 2 carried 0.5% 7,12DMBA painting on left buccal pouch. Groups 3 and 4 were treated with DMBA and 300 mg/kg bwt of PDEAE and PDME by intragastric administration. Remaining groups served as untreated control. All the experiments were performed within 14 weeks. Results: Body weight loss and 100% tumor incidence were observed treated hamsters with DMBA alone, whereas administration of PDEAE and PDME in animals with oral cancer caused significant alterations in body weight and tumor incidence. Further, plasma and buccal pouch tissue glycoprotein levels were increased and erythrocyte glycoprotein levels were depleted in DMBA treated hamsters. The levels were significantly reversed in hamsters treated with PDEAE and PDME at 300 mg/kg bwt. Conclusion: PDEAE and PDME produce a significant protective effect against DMBA induced oral cancer by altering glycoproteins levels.
