Numbers of neurons in submucous (SG) and myenteric ganglia (MG) per mm length of section in stomach (fundus), ileum, and colon from rats treated with saline (C) or buserelin (B). Rats treated with buserelin showed decreased numbers of submucous neurons in the ileum and colon, and myenteric neurons in the fundus, ileum, and colon. Cell-counting was performed on longitudinally-cut, whole-wall sections. Results are presented as individual data and medians. Statistical analyses were performed using the Mann-Whitney U-test, C = 7 rats and B = 9–11 rats. Statistical significance is indicated by *p < 0.05 and **p < 0.01.
