Abstract:
Two ethanolic propolis extracts (EPE) with and without the caffeic acid phenethyl ester (CAPE), CAPE and galangin (major components of propolis) were investigated for anti-inflammatory activity in rats using carrageenin foot oedema, carrageenin pleurisy and adjuvant arthritis. In our experiments, EPE with CAPE and CAPE alone significantly inhibited carrageenin oedema, carrageenin pleurisy and adjuvant arthritis. In contrast EPE without CAPE and galangin did not exhibit anti-inflammatory effects in acute and chronic inflammation. These results suggest that the anti-inflammatory activity of propolis is due to CAPE.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
