| on the hormonal regulation of lipolysis in isolated reindeer adipocytes. | the effects of insulin and bovine growth hormone (bgh) on lipolysis (basal and/or adrenaline-stimulated) were investigated in isolated adipocytes from the norwegian reindeer. addition of 100 nmol l-1 adrenaline to the cells increased lipolysis 20-fold above basal lipolytic rate. insulin (0.i and i nmol l-i) depressed lipolysis significantly at submaximal adrenaline stimulation but had no effect when lipolysis was stimulated maximally. bovine gh (25 and 100 ng ml-i) inhibited basal lipolysis duri ... | 1985 | 3909743 |
| ultrastructure of the cysts of sarcocystis grueneri from cardiac muscle of reindeer (rangifer tarandus tarandus). | cysts of sarcocystis grueneri from cardiac muscle of reindeer (rangifer tarandus) in norway were examined by transmission electron microscopy. the limiting unit membrane of the cyst proper formed regularly spaced invaginations into the cyst at numerous sites coinciding with interruptions in the underlying osmiophilic layer. the primary cyst wall formed numerous strip-like, sinuous protrusions, which were 30-40 nm thick, 150-300 nm wide and up to 4.5 microns long, and were running in parallel wit ... | 1985 | 3922150 |

| central control of expired air temperature and other thermoregulatory effectors in reindeer. | norwegian reindeer (rangifer tarandus tarandus) were provided with chronically implanted hypothalamic perfusion thermodes to determine to what extent expired air temperature (tex) is centrally controlled. the effects that alterations of hypothalamic temperature (thy) had on metabolic heat production, respiratory frequency, respiratory evaporative heat loss, and rectal and leg-skin temperature were simultaneously recorded. experiments were conducted in conscious animals exposed to ambient tempera ... | 1985 | 4003579 |
| seasonal changes in t3, ft4, and cortisol in free-ranging svalbard reindeer (rangifer tarandus platyrhynchus). | serum levels of 3,5,3'-triiodothyronine (t3), free thyroxine (ft4), and cortisol were determined for free-ranging svalbard reindeer during winter (march), summer (june-july), and autumn (october). a total of 48 animals representing adult males, adult barren, pregnant, and lactating females, and calves were shot, and blood sampled from their hearts. t3 and ft4 were found to vary seasonally, the levels being lower in winter than in summer or autumn. differences due to state of pregnancy, sex, or a ... | 1985 | 4018559 |
