Figure 12.10 Oligosaccharides cleaved from native A. barbadensis polysaccharide decrease IL-10 production by UV irradiated murine keratinocytes. From Beyeon etal. (1998). Left Panel, Mice were irradiated with 15,000 J/m2 UV and treated topically with 500 mg per ml oligosaccharide. Four days later skin was removed and cryosections stained for IL-10 by immunohisto-chemistry. Right Panel, subconfluent cultures of PAM 212 cells were irradiated with 300 J/m UV and were then treated for 1 hr with 10 mg per ml oligosaccharide. Cells were washed and IL-10 was detected 24 hrs later by immunohistochemistry (see Colour Plate 8).

Figure 12.11 Tamarind polysaccharides decrease IL-10 production by UV irradiated murine kerati-nocytes. From Strikland etal. (1999). Mice were irradiated with 15,000J/m2 UV and treated topically with Tamarind polysaccharide. Four days later skin was removed and cryosections stained for IL-10 by immunohistochemistry (see Colour Plate 9).
