91.   There is scientific evidence for sexuality in children as studies show that two to three year old boys have regularly recurring erections during REM periods of sleep.

92.   Several studies have shown the association of reflux oesophagitis with lower oesophageal sphincter dysfunction and impaired oesophageal peristalsis.

93.   This study has shown that colonic phenotypic changes are very common in ileal reservoirs when several biopsy specimens are analysed.

94.   The present study also shows a high prevalence of ascites in patients with acute liver failure.

95.   Indeed, animal studies have shown that the presence of a tumour results in increased hepatic protein synthesis.

96.   The present study has shown a cytoplasmic anti-neutrophil antibody, which seems to be more specific than our previously described nuclear anti-neutrophil antibody.

97.   Furthermore, dietary manipulation studies have shown that high fat intake can increase faecal bile acid excretion.

98.   Two early studies showed an increased faecal bile acid excretion in patients with colonic cancer, but later studies have been unable to confirm this.

99.   Our own recent studies have shown an increased proportion of secondary biliary bile acids in patients with colorectal cancer.

100.   In conclusion, our study shows a significant, dose dependent change from absorption to secretion of water and electrolytes in the human jejunum induced by cholera toxin.
