The value of intra-operative cystoscopy at the time of laparoscopic hysterectomy.

The aim of this study was to determine the usefulness of routine intra-operative cystoscopy in documenting ureteral injury during total laparoscopic hysterectomy with vault suspension and to document the incidence of this complication in a large series. The charts of 118 patients who underwent laparoscopic hysterectomy with vault suspension from January 1992 to January 1998 were retrospectively reviewed. The patients underwent intra-operative cystoscopic evaluation to verify ureteral permeability and bladder integrity.

Fecal excretion, uptake and metabolism by colon mucosa of diacylglycerol in rats.

In a previous paper we demonstrated that human fecal bacteria can convert phosphatidylcholine to diacylglycerol (DAG), an activator of protein kinase C. The present study demonstrates that several foods contain appreciable levels of DAG, especially certain vegetable oils. On the other hand, when rats were administered [14C]-labeled DAG by intragastric intubation less than 0.
