Figure 5 Representative glomerular apolipoprotein immunohistochemistry in seven-week OZRs. Sections represent staining in estrogen-supplemented (a, c, ande) and sham-operated (b, d, andf) rats. Specific antibodies against apo A-I (a and b), apo A-IV (c and d), and apo B (e and f) were used. The arrow denotes tubular apo A-IV staining (magnification ×40).
