Objective: Aim of our study was to show how different diets changed liver regeneration after partial hepatectomy (PH). Methods: Male Wistar (W) and Prague Hereditary Hypercholesterolemic rats (PHHC) were divided into groups and fed by different diets ad libitum for 29 days: standard laboratory diet and diet with addition of 4% cholesterol. Two third partial hepatectomy (PH) was then performed. Liver DNA synthesis was estimated by Beckman Coulter analyzer (Beckman, USA). Serum glucose (mmol/l, Modular Roche), leptin and insulin (ng/l, EIA, DRG, Marburg, Germany) were estimated before and after PH. Statistics: t-test (mean ± SEM) was performed using SigmaStat software (Jandel Scientific, USA). Results and Conclusions: There was missing interplay between leptin and insulin with adequate activation of glucose and lipids metabolisms to initiation of liver regeneration in rats with CHOL diet.
