Figure 5: Liver, renal, and pulmonary function results. (a) and (b) Changes in ALT and AST of rat liver after TNBS-ethanol enema. (c) and (d) Changes in BUN, and Cr of rat liver after TNBS-ethanol enema. TNBS-ethanol enema resulted in a slightly decrease but no significant change in serum concentration of ALT, AST, BUN, and Cr when compared with the normal both in 24 hours and 4 weeks (). (e) Results of pulmonary function tests after TNBS-ethanol enema. Ri: resistance of airways at inspiration; Re: resistance of airways at expiration; CL: lung compliance; MVV: maximal voluntary ventilation; FVC: forced vital capacity; FEV0.2: forced expiratory volume in 0.2 second; FEV0.2/FVC: ration of FEV0.2 and FVC in %; PEF: peak expiratory flow; FEF25%–75%: and forced midexpiratory flow rate.
