Figure 4  .

Cryostat sections from rat, sham operated (A and E), one week (B and F), four weeks (C and G), and 10 weeks (D and H) bypassed ileum autoradiographically labelled for VIP mRNA (A-D) and galanin mRNA (E-H). VIP mRNA containing submucous neurones (indicated by arrows) are intensely labelled in sham operated ileum (A) but only weakly labelled in the bypassed ileum (B-D). The labelling of galanin mRNA containing enteric neurones is equally intense in both sham operated (E) and bypassed (F-H) ileum. Original magnification × 130.
