Abstract

Marine sponges are animals belonging to the Phylum Porifera. They are well known for its medicinal value. However, to prove its efficiency for the clinical utilization, more experimental data will be beneficial. The present study involved the investigation of immunomodulatory activities of ethyl acetate extract of marine sponge Aurora globostellata from Tuticorin coast of India. The extract was studied for acute toxicity (OECD-425 guideline), Haemagglutinating antibody (HA) titre and delayed-type hypersensitivity (DTH) response for their immunomodulatory potential. The evaluation of immunomodulatory potential by oral administration of ethyl acetate extract of marine sponge (200 mg/kg) evoked a significant decrease in total WBC count as compared to control, in antibody titre values, and also in delayed type hypersensitivity reaction induced by sheep red blood cells. The results obtained in the present study indicated that extract of marine sponge Aurora globostellata possesses immunosuppressant activity and can be studied further for isolation of the compounds which can be used for organ rejection purpose in future.
