    Notes: Summary A synthetic approach has been applied to determine the profile of sequential determinants of one immunodominant region ofTissuePolypeptideAntigen (TPA). Five overlapping peptides, covering 30 of the 32 amino acid residues of this fragment, were chemically synthesized, and their antibody-binding activities for rabbit anti-TPA antibodies determined by enzyme-linked immunoadsorbant assays. Anti-TPA reacted with two overlapping fragments at the COOH-terminal end of the fragment, but not with peptides that include Arg 15 considered as essential for the antigenicity of the whole fragment. This might suggest that this critical residue is involved in the formation of a complex conformational determinants.

    Notes: Abstract The effects of Sulglycotide were evaluated in a pilot study of activeH. pylori + atrophic gastritis. Ten informed patients (mean age 51±13 years) entered a double-blind study. Five received Sulglycotide 400 mg three times a day for one year, the other 5, placebo. At 0, 30, 90, 270, and 360 days of treatment, patients underwent endoscopic examinations with multiple biopsics. Morphometric studies (number of inflammatory cells and percent gland volume), morphologic studies (according to the Sydney system), and flow cytofluorimetry were performed in all cases. Compared to findings in the placebo group, patients treated with Sulglycotide showed a reduced number of inflammatory cells and an increase in gland volume 120 days after treatment. While the difference was not statistically significant, the trend was confirmed by the morphologic patterns. Flow cytofluorimetry revealed an increase in the percentage of cells in the G2 phase (full maturation) and a parallel drop in the S phase (premitotic synthesis) in the Sulglycotide group only in the first three months. These data would appear to indicate an acceleration of gastric epithelial cell maturation and a decrease in the inflammatory infiltrate under the effect of Sulglycotide.
