• dermal edema is decreased by 41% within 6 hours of croton oil irritation in young mice (7-14 weeks), and partial suppression of edema in older (23-35 weeks) mice

cellular

impaired neutrophil chemotaxis ( J:112286 )

• migration is completely defective in acute croton oil dermatitis model in young mice (7-14 weeks); older mice show complete abrogation of neutrophil migration in response to irritation

immune system

abnormal leukocyte migration ( J:24239 )

• Streptococcus pneumoniae induced peritonitis eliminated neutrophil emigration into peritoneum

• Streptococcus pneumoniae induced pneumonia did not reduce neutrophil recruitment or edema formation in the alveolar space

increased neutrophil cell number ( J:24239 )

• 4-5 fold increase in numbers of circulating neutrophils
