Chloride-sensitive glucose transport in Hymenolepis diminuta.

The maximal rate of glucose influx in Hymenolepis diminuta decreased when CL- in the incubation medium was replaced with acetate, benzoate, bicarbonate, formate, hippurate, iodide, lactate, mandelate, or nitrate. The effect of Cl- deletion on glucose influx using any of these anions was reversed when worms were incubated in Krebs-Ringer saline for 15 min. Glucose in the incubation medium increased 36Cl- influx in worms, while in Na+-free media the presence of glucose had no effect on 36Cl- influx. Influx of 10 mM 36Cl- in H. diminuta was inhibited by unlabeled Cl- in the incubation medium. Hymenolepis diminuta accumulated glucose aginst an apparent concentration differnce when Cl- in the incubation media was replaced with acetate, bicarbonate, or nitrate. The influx of Cl- appears couples with the influxes of Na+ and glucose, but the data do not show whether the influxex of these molecules are mediated through a common "carrier."

Comparison of transdermal fentanyl and intramuscular oxymorphone on post-operative behaviour after ovariohysterectomy in dogs.

The effects of transdermal fentanyl and i.m. oxymorphone on behavioural and physiological responses, after ovariohysterectomy in dogs, were investigated. The study involved three groups of 10 dogs: fentanyl/surgery (FS), oxymorphone/surgery (OS), fentanyl/control (FC). A transdermal fentanyl delivery system (50 microg hour(-1)) (FS and FC) was applied 20 hours before surgery, or i.m. oxymorphone (OS) was administered. After ovariohysterectomy (FS and OS) or anaesthesia alone (FC), dogs were continuously videotaped for 24 hours and a standardised hourly interaction with a handler performed. The videotapes were analysed, and interactive and non-interactive behaviours evaluated. In addition, pain and sedation scores, pulse and respiratory rates, rectal temperature, arterial blood pressure, plasma cortisol and plasma fentanyl concentrations were measured. This study showed that transdermal fentanyl and i.m. oxymorphone (0.05 mg kg(-1)) produced comparable analgesic effects over a 24 hour recording period. I.m. oxymorphone produced significantly more sedation and lower rectal temperatures than transdermal fentanyl. There were no significant differences between groups in respiratory and heart rates, and arterial blood pressures.

Prader-Willi syndrome.

Prader-Willi Syndrome (PWS) is a relatively common complex genetic disorder that is diagnostically and therapeutically challenging to health-care professionals. Nursing observations of significant neonatal feeding problems may assist in identification of the infant with PWS. Once nurses become familiar with the characteristics of this multi-system condition, they can provide specific assistance to PWS infants and their families.
