Figure 3. Immunohistochemistery (IHC) for Evaluation of TNF-α expression on spleen tissue. Immunohistochemical analysis of TNF-α expressions in spleens of untreated control group (A), methotrexate-treated group (B), papaya-treated group (C), kiwifruit-treated group (D). High expression of TNF-α was seen in the methotrexate-treated group (strong staining, 111). Meanwhile, the lowest expression of TNF-α was found in group treated with methotrexate and kiwifruit (weak staining, 1). TNF-α expression was indicated with black arrows. Stained by DAB -chromogen (Brown color) immunostaining.
