[Comparative biochemical effects of the injection of cyclic and linear forms of vertebrate somatostatin on the honeybee in vivo. II. Blood lipids].
The linear and cyclic forms of vertebrate somatostatin were injected to worker honeybees at the rate of 50 ng per individual, and their effects on the lipemia were compared between themselves and with those of saline injection over a 3 hrs period. Both hormonal forms elicit a global decrease of the levels of phospholipids, steroids, fatty acids, diacyl and triacyl glycerol, by contrast with hyperlipemic effects induced by the injection of saline alone. The kinetics of variations show a remarkable phase concordance between the respective effects of both hormonal forms, with strong positive correlations in the case of phospholipids, fatty acids and glycerides. The linear and cyclic forms of somatostatin thus show similar effects counteracting the results of the release of endogenous hormones following the stress associated to the microsyringe stinging.
