| Abstract: | It was shown in experiments in vitro that high density lipids (HDL), very low density lipids (VLDL) and cAMP taken separately did not affect the kinetics of mitochondrial swelling in the liver of control and 72-hr-fasting rats. ApoHDL and particularly ApoVLDL obtained by delipidation of appropriate lipoproteins had pronounced capacities to stimulate the process of swelling. Mitochondrial swelling increased to an ever greater degree under the action of cAMP coupled with apoproteins. The maximum stimulation of the swelling was attained as a result of administering apoVLDL in conjunction with cAMP. The effects of enhanced swelling were the most remarkable in experiments with mitochondria from the control animals. |
