A. Sood et al., Effect of chronic morphine administration on glucose tolerance and insulinbinding to isolated rat adipocytes, ENDOCRINE R, 27(1-2), 2001, pp. 215-221
Morphine addiction was induced in six male Wistar rats. Improved glucose to
lerance (peak value less by 28%, p < 0.01) was observed in chronically morp
hinized rats as compared to the control rats, injected with saline. An incr
ease in the maximal specific binding of I-125-labeled insulin to unit membr
ane area of adipocytes was observed in the experimental group (p < 0.01). T
he changes in insulin receptor number could be responsible for the improved
glucose tolerance observed during morphine addiction.
