Postoperative course of facial nerve function appears predictable using intraoperative continuous monitoring of evoked facial nerve EMGs. This monitoring is useful to increase the tumor excision rate while avoiding severe postoperative facial nerve palsy in acoustic neuroma surgery.

The increase in Ca transport involved two mechanisms: the presence of DFAIII in the small intestine directly affected the epithelial tissue and caused increased Ca absorption as a short-term effect, and the degradation of DFAIII by microbial fermentation produced short-chain fatty acids and subsequently enhanced Ca absorption in the large intestine as a long-term effect.

The effects of three indigestible disaccharides on net calcium (Ca), magnesium (Mg), and zinc (Zn) transport in isolated rat jejunal, ileal, cecal, and colonic epithelium were determined. Permeability of fluorescein isothiocynate-dextran-4 (FD4) and transepithelial electrical resistance (TEER), which vary according to tight junction (TJ) activity in the intestinal mucosa, were also determined. The addition of 1-100 mM melibiose, difructose anhydride (DFA) III, or DFA IV to the mucosal medium increased the net absorption of the three minerals and FD4 permeability, while decreasing TEER dose dependently in the four intestinal portions. Positive linear relations were found between the net transport of the three minerals and FD4 passage in all portions of the intestine, whereas negative linear relations were observed between net absorption of the three minerals and TEER. We concluded that the three indigestible saccharides directly affect the epithelial tissue and open TJs, thereby promoting Ca, Mg, and Zn absorption in the small and large intestine in vitro.
