Abstract

Periodic, for 3 days, incubation (2 h) of 24-week-old molluscs in a 100 mmol/L aqueous solution of glucose leads to an almost 5-fold increase in the glucose content in the haemolymph, 24 h after the hyperglycemic impact. For animals 35 weeks of age, this impact does not lead to a statistically significant change in the considered indicator. It was found that the level of glucose in the haemolymph of animals of the older age group (0.21 (0.13; 0.23) mmol/L) exceeded that of animals of the younger age group (0.13 (0.08; 0.16) mmol/L) in 1.6 times. It is assumed that these features of glucose regulation are associated with the functional characteristics of peptide-producing neurosecretory cells of the central nervous ganglia.
