| Popis: | v anglickém jazyce: Thesis abstract: Background and aims: Both obesity and metabolic syndrome form severe health problems in the whole world. Nevertheless the armament of pharmacotherapy for both diseases remains unsatisfactory. We aimed our work to main organs in risk of the mentioned diseases -liver and visceral fat using hepatocytes and visceral adipocytes as model. We detected 3 main metabolic and signalization activities- glycogenolysis, Nitric oxide (NO) production and transcription of inducible NO synthase (iNOS) in hepatocytes, lipolysis, NO production and iNOS transcription rate in adipocytes. We directed our interest to combination of peroxisome proliferation activator receptor γ (PPARγ) agonist, antagonist and β3 adrenergic agonist in the culture of epididymal rat adipocytes in the first part of our work. While in the second part we investigated the influence of β and α adrenergic mimetics, adrenergic blockers in the culture of rat high glycogen content hepatocytes. Methods: NO production was detected under the active agents treatments by detection of NO oxidative products NO2 and NO3 in media. Glycogenolysis was measured as free glucose rise released by hepatocytes into the media. NOS transcription level was extrapolated after comparative polymerase chain reaction with reverse... |
