Using the COPE assessment tool with informal carers of people with dementia in New Zealand.

Aims: To evaluate the validity of the COPE index (CI) carer assessment tool within a study exploring perceptions of carer support, health, and wellbeing. To assess the utility and acceptability of the CI with health practitioners and informal carers of people with dementia, following the European COPE protocol.

Methods: Research interviews (one pre- and two post-CI assessment) recorded demographic characteristics of carer (n = 45) and care recipient, formal (service) and informal support use and satisfaction, self-reported health, the General Health Questionnaire (GHQ-30), Burden Interview, Caregiver Competence, and Personal Gain.

Effect of insulin-induced hypoglycaemia on secretion patterns and rates of corticotrophin-releasing hormone, arginine vasopressin and adrenocorticotrophin in horses.

To study the effect of hypoglycaemia on secretion rates of corticotrophin-releasing hormone (CRH), arginine vasopressin (AVP) and ACTH in a non-ruminant species, a non-surgical method was used to collect pituitary venous (PitVen) blood every 0.5 or 1 min from seven horses before and after insulin administration (0.4 U/kg i.

The effect of various corticotropin-releasing factor trains on the release of adrenocorticotropin, beta-endorphin, and beta-lipotropin from perifused ovine pituitary cells.

The dynamics of the release of proopiomelanocortin-derived hormones from ovine anterior pituitary cells in response to varying pulse characteristics of ovine corticotropin-releasing factor (CRF) were investigated with an in vitro automated 15-column simultaneous perifusion system. Columns of cells were stimulated continuously or with trains of CRF pulses of varying pulse length (2-16 min), pulse period (20-160 min), and concentration, for 500 min. Ovine ACTH, beta-lipotropin, and beta-endorphin immunoreactivity were measured by unextracted RIA.

Effects of an enkephalin analogue (DAMME) on pituitary and pancreatic function in sheep.

The hormonal secretory effects of intravenously and intracerebroventricularly administered DAMME have been studied in the sheep. Serum prolactin and growth hormone levels were significantly elevated after i.v.

Hormonal effects and metabolic clearance rate of the enkephalin analogue DAMME in man.

The enkephalin analogue DAMME (0.25 mg) and normal saline were administered by slow intravenous injection to six normal male subjects in a double-blind crossover study. Plasma DAMME concentrations were measured by a specific radioimmunoassay.
