Stabilized-solubilized ferric pyrophosphate as a new iron source for food fortification. Bioavailability studies by means of the prophylactic-preventive method in rats.

The purpose of the present work was to evaluate the iron bioavailability of a new ferric pyrophosphate salt stabilized and solubilized with glycine. The prophylactic-preventive test in rats, using ferrous sulfate as the reference standard, was applied as the evaluating methodology both using water and yogurt as vehicles. Fifty female Sprague-Dawley rats weaned were randomized into five different groups (group 1: FeSO(4); group 2: pyr; group 3: FeSO(4) + yogurt; group 4: pyr + yogurt and group 5: control).

[Superselective spinal anesthesia for saphenectomy intervention. Comparison of 2 concentrations of hyperbaric bupivacaine].

Background: High concentrations of intrathecal local anaesthetics may be neurotoxic. The purpose of this study was to compare the features of superselective spinal anaesthesia (ASS) obtained with an equivalent dose (5 mg) of 0.5% (available now also in Italy) and 1% hyperbaric bupivacaine.

[Peridural anesthesia with 0.5% bupivacaine-fentanyl. Evaluation of the pre-heating effect].

The effect of preheated (37 degrees C) mixture of 0.5% bupivacaine and fentanyl on peridural anaesthesia have been studied in a double blind randomized clinical trial. Fifty patients of both sexes, ASA I-II, undergoing elective surgery for inguinal hernia repair or radical saphenectomy have been randomly assigned either to the control group (n = 25) receiving 0.

[Loco-regional analgesia with continuous peridural technique in labor. Evaluation of 4 years of experience].

The Authors report on the results of their experience using local-regional analgesia performed with the continuous peridural technique over four years of activity with 503 pregnant women. Protocols used over the years called for morphine-fentanyl association, but bupivacaine 0.25% plus fentanyl and bupivacaine 0.
