  • Title: Inhibition of the lipolytic response to nerve stimulation during acidosis.
    Author: Hjemdahl P.
    Journal: Acta Physiol Scand; 1976 Sep; 98(1):80-4. PubMed ID: 970159.
    Abstract:
    Acidosis inhibits catecholamine-induced lipolysis in vivo and in vitro. The lipolytic response of canine subcutaneous adipose tissue to short (5 min) nerve stimulations at 4 Hz was, however, not influenced by hypercapnic acidosis (pH 7.0). The steady state outflow of glycerol during a prolonged nerve stimulation at 4 Hz was inhibited by 40 per cent (p less than 0.05) at pH 7.0. Similarly, glycerol outflow during vasodilatation induced by a 4 Hz stimulation in alpha-blocked adipose tissue was inhibited by 37 per cent (p less than 0.05). Post-stimulatory glycerol outflow was, however, not influenced by acidosis. This poststimulatory glycerol outflow, which may represent a complex wash-out phenomenon, forms the largest part of the response to short nerve stimulations. It is suggested that steady state, rather than poststimulatory lipolysis should be studied in order to see the influence of treatments such as acidosis on responses to nerve stimulation.
