From stem bark of Callistemon rigidus (Myrtaceae), piceatannol and scirpusin B were isolated as components that exhibit inhibitory effects on a a -amylase activity in isolated mouse plasma. In particular, scirpusin B also inhibited a a -amylase in mouse gastrointestinal tract. Thus, we expect the depressive effect on the elevation of postprandial blood glucose may be a new medicinal use of this compound as well as the plant itself.
The safety and effectiveness of laparoscopic treatment for incarcerated inguinal hernia have not been clarified. Six patients who underwent laparoscopic reduction and repair of incarcerated inguinal hernias were reviewed retrospectively. All operations were initiated within 1 h after establishment of the diagnosis. Laparoscopically, the incarcerated small-bowel segments could be easily returned to the abdominal cavity by a combination of pulling them with Babcock forceps while pushing back the bowels from outside the abdominal wall. The hernial portals were not cut in three patients, while they were dissected in the other three. All incarcerated bowels were congested and red immediately after reduction; however, their color returned to normal during hernia repair and unnecessary bowel resection was therefore avoided. The mean operation time was 88 min. Although one patient underwent laparotomy because of the suspicion of necrosis of the incarcerated inguinal hernia, which was finally found to be due to postoperative paralytic ileus, the postoperative courses of the remaining five were uneventful. Laparoscopic reduction and repair of incarcerated inguinal hernia was useful, and unnecessary bowel resection could be avoided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
