S.; Van Vuuren, I.; Op't Hof, J.The incidence of cleft lip and palate in the Western Cape was studied using data from two cleft palate centres and from all plastic surgeons in practice in the area.

- ItemNeurotensin, vaso-active intestinal polypeptide and gastrin levels in plasma and protal venous blood in experimental mesenteric ischaemia(Health & Medical Publishing Group, 1991) Van Rensburg, L. C. J.; Morrison, G.; De Beer, R.; Strachan, A. F.The effect of mesenteric ischaemia on the levels of neurotensin, vaso-active intestinal polypeptide and gastrin in portal venous blood and in the peripheral circulation was studied in two groups of 7 and 6 baboons (Papio ursinus). In peripheral blood a decreasing trend in levels of neurotensin was observed, while vaso-active intestinal polypeptide and gastrin levels were unchanged. There was a similar trend in neurotensin levels in portal venous blood, together with an increasing trend in levels of vaso-active intestinal polypeptide. Gastrin levels were unchanged. Further investigation of these apparent trends in a large number of animals is warranted.
