Two membranes of different molecular weight cut-off, namely, 30 kD and 10 kD were chosen with ultrafiltration. The antioxidant activity of the purification polysaccharides was evaluated by various antioxidant assay, including DPPH （l,l-diphenyl-2-picrylhydrazyl） radical scavenging, superoxide anion radical scavenging and hydrogen peroxide scavenging. The scavenging effect on hydroxyl radical and DPPH radical, which may be comparable to Vitamin C, while the scavenging effect on superoxide anion radicals was not obvious.展开更多

Available data is encouraging for the safe application of standardized SIL in a wide range of procedures in gastroenterology and hepatology. Compared to technically simple SIL procedures, the merit of SIL in advanced surgeries, such as liver or colorectal interventions, compared to conventional laparsocopy is self-evident without any doubt. SIL has already passed the learning curve and is routinely utilized in expert centers. This minimized approach has allowed to enter a new era of surgical management that can not be acceded without a fruitful combination of prudent training, consistent day-to-day work and enthusiastic motivation for technical innovations. Both, basic and novel technical specifics as well as particular procedures are described herein. The focus is on the most important surgical interventions in gastroenterology and aims at reviewingthe current literature and shares our experience in a high volume center.展开更多
