Serial liver biopsies were carried out in 67 patients with HLP and/or fatty liver before, during short- and long-term therapy with CPIB and after termination of therapy. Results (1) Decrease of liver glycogen from 4.17% to 2.69% (wet weight, P less than 0.02). (2) Insignificant changes of liver triglyceride content. (3) Significant decrease of manganese, while the concentrations of zinc and copper in the liver biopsy specimens remained unchanged. (4) No signs of liver intoxication or cancerogeneous effects of light-microscopic pictures. (5) Significant increases in numbers of mitochondria and cristae as well as a hypertrophy of endoplasmic reticulum with longer lasting therapy. (6) Striking focal proliferation of cristae mitochondriales in 3 cases on longterm treatment. (7) Regression of the mitochondrial alterations after termination of the CPIB therapy. Our findings suggest that an increased number of mitochondria and of their inner membranes in the liver cells induced by CPIB could play an important role in the hypolipidemic action of the drug.

The applicability of the in vivo proton magnetic resonance spectroscopy hepatic lipid profiling (MR-HLP) technique in nonalcoholic fatty liver disease was investigated. Using magnetic resonance spectroscopy, the relative fractions of diunsaturated (fdi), monounsaturated (fmono), and saturated (fsat) fatty acids as well as total hepatic lipid content were estimated in the livers of 8 control and 23 CCl4-treated rats at 9.4 T. The mean steatosis, necrosis, inflammation, and fibrosis scores of the treated group were all significantly higher than those of the control group (P < 0.01). There was a strong correlation between the histopathologic parameters and the MR-HLP parameters (r = 0.775, P < 0.01) where both steatosis and fibrosis are positively correlated with fmono and negatively correlated with fdi. Both necrosis and inflammation, however, were not correlated with any of the MR-HLP parameters. Hepatic lipid composition appears to be changed in association with the severity of steatosis and fibrosis in nonalcoholic fatty liver disease, and these changes can be depicted in vivo by using the MR-HLP method at 9.4 T. Thus, while it may not likely be that MR-HLP helps differentiate between steatohepatitis in its early stages and simple steatosis, these findings altogether are in support of potential applicability of in vivo MR-HLP at high field in nonalcoholic fatty liver disease.

LDLP and VLDLP have different biological functions: phylogenetically older LDLP transfer FA that serve as substrates for intracellular production of energy and ATP while VLDLP transfer FA--precursors of cell membranes and eicosanoids. The cells absorb LDLP via apoB-100 endocytosis and VLDLP through apoE/B-100 receptors. VLDLP consist of palmitic and oleic VLDLP and LDLP of linoleic and linolenic LDLP. The contribution of LDLP to the development of HLP atherosclerosis and atheromatosis is negligible. LDLP form palmitic and oleic VLDLP with hydrated LDLP density. Blockade of LDLP absorption by apoB endocytosis and deficit of poly-FA constitute the etiological basis of atherosclerosis. Its pathogenetic basis is the excess of palmitic VLDLP with LDPL density in the intercellular space that block absorption of linoleic LDLP with all transferred SC poly-FA. Atheromatosis is clinically and prognostically most significant symptom of atherosclerosis associated with accumulation of ligand-free VLDLP and LDLP in arterial intima of the elastic type as the local pool of interstitial tissue for intravascular pool of intercellular medium. Type 2 diabetes mellitus in aged patients is a symptom of atherosclerosis resulting from SC poly-FA deficit and GLUT4 incompetence. Insulin-dependent cells differ in the degree of insulin resistance. Non-alcoholic fatty liver disease, synthesis of a physiological palmitic TG by hepatocytes and excessive formation of palmitic VLDLP in liver integrate pathogenesis of atherosclerosis and hepatic steatosis. The main pathogenetic factor is the excess of palmitic s-FA and palmitic TG.
