Enriched-Baicalein Attenuates Allergy in Cells and Mice

Figure 5

Histological analysis by baicalein administration in ovalbumin applied Balb/c mice. Balb/c males (6 weeks old) were used and ovalbumin was injected intraperitoneally for 0, 7, 14, 21, and 28 days to Balb/c (n = 5). The baicalein, containing 100 mg of baicalein/kg body weight per day dissolved in 0.4% polyethylene glycol in 0.5% EtOH, was applied topically on a daily basis. After four weeks, the lung was stained with hematoxylin and eosin and histological analysis was carried out under a light microscope at 250x magnification. (a) Normal group; (b) ovalbumin control group; (c) dexamethasone group; (d) Scutellaria baicalensis Georgi extract group; (e) baicalein group.
