The mixture inhibits protein tyrosinc phosphatase（SHP-1） function, implying it enhances immune activity. The peak molecular mass of the oligosaccharide portion is 1800 calculated via GPC software after separation by HPLC. And the structure of the oligosaccharide portion is the backbone of （1→3）- and （1→4）-linked arabinopyranoside, and （1→4）- and （1→6）-linked glucopyranoside, with non-reducing terminals of arabinopyranoside and glucopyranoside. The peak molecular mass of glycopeptide portion is 1900 calculated via GPC software after separation by HPLC. The structure of glycopeptide portion is the backbone of （1→3）- and （1→4）-linked arabinopyranoside, and （1→3,6）-linked glucopyranoside, with non-reducing terminals of galactopyranose and glucopyranoside. The peptide composition is Glu. Asp, Hyp, Set, Arg, Gly , Thr, Pro, Ala, Val, lie, Leu and Lys. The oligosaccharide-peptide linkage is formed by Ara and Hyp.展开更多

Moreover, it is well known that there is a correlation of these symptoms with Erectile Dysfunction (ED) that can reach a frequency of roughly 52% in men aged between 40 and 70 years old. In this study, we aimed at evaluating the effect of a new natural compound “Tradamixina TP” (composed of 80 mg of the algae Ecklonia Bicyclis, 100 mg of Tribulus terrestris and 100 mg of Chitosan Water-soluble oligosaccharide 320 mg of Serenoa repens) in the improvement of Lower Urinary Tract Symptoms (LUTS). Materials & Methods: One-hundred patients with an average age of 64 years old and who were not taking any medication or phytotherapy for prostatic hypertrophy or erectile dysfunction were recruited in the study. All participants were subjected to serum prostate antigen (PSA) and uroflowmetry measuring maximal urine flow/sec (Qmax), at baseline and after 12 weeks. In addition, patients were asked to take the Tradamixina TP for 3 months and to complete at the beginning and end of the treatment the following questionnaires: 1) the IPSS investigating the level of LUTS, and 2) the IIEF-15 investigating the erectile dysfunction. Results: After the treatment, the IPSS scores were lower than those before the treatment. Moreover, a significant effect was found for the IIEF erectile subdomain with scores that were significantly higher at 12 weeks than at baseline. A similar result was found for the IIEF overall subdomain. A decrease of total serum PSA was also observed. Conclusions: After 3 months of daily treatment, the new compound “Tradamixina TP” improved patients’ sexual function, LUTS and led also to a decrease in serum PSA levels.展开更多
