Lip adhesion and its effect on the maxillofacial complex in complete unilateral clefts of the lip and palate.

The use of a lip adhesion as part of the treatment program for wide complete clefts of the lip and palate is gradually being accepted. Heretofore, little mention has been made as to its actual beneficial effects. Since the introduction of this procedure by our Group in 1966, it has been used routinely by us. Its effects on the maxillofacial complex is discussed in detail.

Comparison of the metabolism of testosterone undecanoate and testosterone in the gastrointestinal wall of the rat in vitro and in vivo.

The metabolism of testosterone undecanoate (TU) and testosterone (T) is studied in the gastrointestinal wall of the rat in vitro. A comparison is made with the in vivo metabolism of these compounds in the rat. The major metabolite first appearing during incubation of TU with the small intestine is T. Incubation of TU or T with the small intestine reveals a great similarity between the metabolite patterns obtained. This is also the case with the patterns derived from portal vein plasma upon oral administration of TU and T. Incubation of different parts of the gastrointestinal tract with TU or T shows that the greatest metabolic activity is located in the wall of the small intestine. Unlike T, TU is metabolized only to a small extent in the wall of the stomach and the large intestine.
