The anti-arthritic effects of glucosamine incorporated in a chicken-meat extract known as Brand’s Glucosamine
with Essence of Chicken versus glucosamine or Essence of Chicken (EOC) alone were investigated on collagen
induced arthritis (CIA) in dark agouti (DA) rats. Four groups of rats received basic food (control), 1.2%
glucosamine (GLU), 0.8% EOC and 1.2% GLU + 0.8% EOC (GLU + EOC) admixed with basic food for 25 days
following CIA. Foot pads were isolated on day 25 for histopathological evaluation. Clinical assessment of hind
paw swelling as measured by foot pad volumes and histopathological scoring based on the degree of edema,
periosteal new bone formation, periostitis and inflammatory cell infiltration of the isolated foot pad were
performed. Arthritic rats given GLU + EOC showed significant reduction in left hind paw swelling following onset
of arthritis. Correspondingly, a lesser degree of edema, periosteal new bone formation, periostitis and inflammatory
cell infiltration was seen in histological sections of the left hind foot pads of these rats. A similar trend of reduced
hind paw swelling was observed in the right hind paws of the same rats and those fed with EOC. Rats fed with
GLU alone did not demonstrate these beneficial effects. The present findings demonstrate that a combination of
glucosamine and EOC is effective in reducing the histopathological severity of arthritis, probably due to its ability
to reduce the inflammatory conditions in CIA.
