The HemoScreen, a novel haematology analyser for the point of care.

Background And Aims: A haematology analyser, based on a new technology, is presented herein. The analyser that provides a complete blood count (CBC) and five-part differential accepts disposable cartridges containing all required reagents, making it maintenance-free and ideal for point-of-care (POC) settings. The test reproducibility and imperviousness to analytical errors are attributed to the imaging-based analysis employed.

Monitoring the respiratory rate by miniature motion sensors in premature infants: a comparative study.

Objective: Existing respiratory rate (RR) monitors suffer from inaccuracy. The study assesses the accuracy of a novel modality that monitors lung ventilation with miniature motion sensors.

Study Design: RR was measured by three methods: impedance technology, motion sensors and visual count, in babies (n=9) that breathed spontaneously or with respiratory support and babies (n=12) that received high-frequency oscillatory ventilation (HFOV).

Emergence behaviour in children: defining the incidence of excitement and agitation following anaesthesia.

Background: Children display a variety of behaviour during anaesthetic recovery. The purpose of this study was to study the frequency and duration of emergence behaviour in children following anaesthesia and the factors that alter the incidence of various emergence behaviour following anaesthesia.

Methods: A prospective study of children who required outpatient lower abdominal surgery was designed to determine an incidence and duration of emergence agitation.

Regional anaesthesia decreases the need for postoperative mechanical ventilation in very low birth weight infants undergoing herniorrhaphy.

Background: We were interested to know whether regional anaesthesia allowed improved respiratory function postoperatively in very low birth weight babies.

Methods: We performed a retrospective study to examine the association between regional anaesthesia and postoperative ventilation after herniorrhaphy in very low birth weight infants. Thirty-four prematurely born infants underwent herniorrhaphy from 1995 to 1997 at St Louis Children Hospital.

Caudal epidural anesthesia in conscious premature and high-risk infants.

Twenty premature or high-risk infants received caudal epidural anesthesia for inguinal herniorrhaphy, orchiopexy, and circumcision. Mean gestational age at surgery was 48 +/- 12 weeks; mean weight at surgery was 4,100 +/- 1,400 g. Caudal anesthesia, performed with 1 mL/kg of 0.

Intrasplenic islet isografts.

Sufficient numbers of pancreatic islets transplanted into the splenic pulp of streptozotocin-induced diabetic rats can result in complete reversal of hyperglycemia, glycosuria, and polyuria while promoting weight gain. These changes are constant for at least 3 months. Animals transplanted in this way, however, fail to exhibit a normal biphasic insulin response during an intravenous glucose tolerance test.

Enzyme studies in the articular cartilage of diabetic rats and of rats bearing transplanted pancreatic islets.

The articular cartilage of normal rats, of rats made diabetic with streptozotocin, and of rats made diabetic with streptozotocin and subsequently transplanted with isologous pancreatic islets was examined for the activities of enzymes engaged in the synthesis and degradation of glycosaminoglycans (mucopolysaccharides). The activities assayed were those of the degrading enzymes B-glucuronidase, B-acetyglucosaminidase, B-acetylgalactosaminidase, B-galactosidase, and those active in synthesis: uridine diphosphate dehydrogenase, glucose-6-phosphate dehyrogenase, and phosphofructokinase. In the diabetic animals all enzyme activities were increased, thos of the degrading enzymes more than those of the others.

Radioautographic analysis of the distribution of label from h-indoleacetic Acid supplied to isolated coleus internodes.

Isolated fifth internodes of Coleus blumei Benth. were supplied with (3)H-IAA at their apical ends. Microradioautography, using thin sections (0.
