Figure legends
Figure (1) Maximum angle of knee extension with zero degree
represent as the maximum possible extension (Rezende et
al., 2006)
Figure (2) : The histopathological findings of
different groups. I : Non-osteoarthritic group showing articular
cartilage (AC) with its smooth surface (arrow). The chondrocytes appear
in the matrix (curved arrow). Subchondral bone (B) and bone marrow (BM)
are seen, allocated Grade-0. IIa : OA group showing
marked erosion of articular cartilage surface with marked matrix loss
(arrow), decreased number and size of chondrocytes with some cell death
(curved arrow) and some cavities in the subchondral bone (asterisk),
allocated Grade-4. IIb : OA group showing irregular surface
(arrow), disorientation of chondrocytes with some cell death (arrowhead)
and presence of multiple cavities (asterisk), allocated grade 3.III : Glucosamine treated OA group: Showing discontinuous
superficial layer of articular cartilage (arrow), increase in the number
of chondrocytes, with cluster formation (arrowhead), some cell death
(asterisk), matrix loss (tailed arrow) and increase in cartilage
thickness, allocated Grade-2 (Group 3, H & E X 400). IV :
diacerein treated OA group showing an irregular surface of articular
cartilage (arrow), increase in the number of chondrocytes, disturbed
morphology with cluster formation (arrowhead), some cell death
(asterisk) and increase the cartilage thickness, allocated Grade-2.V : atorvastatin treated OA group showing a nearly smooth
surface of articular cartilage (arrow), a slight increase in the number
of chondrocytes with the initiation of cluster formation, condensation
of cells in the superficial layer (arrowhead) and increase the cartilage
thickness, allocated Grade-1. (H&E, X400).
