Figure 7From: Inhibition of allergic airway responses by heparin derived oligosaccharides: identification of a tetrasaccharide sequenceLung histology samples in ovalbumin immunized mice. Top Panel: Control mice challenged with aerosolized saline; there is no evidence of peribronchial and perivascular inflammation. Middle Panel: Mice challenged with aerosolized ovalbumin; marked peribronchial and perivascular inflammation is seen with eosinophil infilteration. Bottom Panel: Ovalbumin challenged mice after pretreatment with nebulized heparin tetrasaccharide; reduced peribronchial and perivascular inflammation. Hematoxylin and eosin stain ( × 64 magnification).Back to article page
