Genetic diseases of the liver
Šepsová, Marika ; Doleželová, Eva (advisor) ; Tripská, Katarína (referee)
Author: Marika Šepsová Title: Genetic diseases of the liver Form: Bachelor Thesis University: Charles University, Faculty of Pharmacy in Hradec Králové Degree: Medical Laboratory Technician Liver function may be affected by various factors including genetic diseases. The aim of this bachelor thesis is to collect and summarize current information about genetic diseases of the liver. Diseases with the highest incidence in the population are Dubin-Johnson syndrome, Rotor syndrome, Crigler-Najjar syndrome and Gilbert's syndrome. They are known as inherited hyperbilirubinemia characterized by an impairment in bilirubin metabolism. These genetic diseases are very rare with exception of Gilbert's syndrome. However, despite low prevalence and incidence it is necessary not to prolong their diagnosis. Most of them do not have any complications and do not require any treatment. The exception is Crigler-Najjar's syndrome, as untreated can have fatal consequences. Wilson's disease and hereditary hemochromatosis are inherited disorders of metal metabolism. Wilson's disease is a rare disease caused by an impairment in copper metabolism. Inherited hemochromatosis causes excessive iron deposition in the liver and other organs. Alpha-1 antitrypsin deficiency is characterized by impaired alpha-1 antitrypsin protein...

Influence of resveratrol on bile flow.

Kristýna Paclíková Influence of resveratrol on bile flow Diploma thesis Charles University in Prague, Faculty of Pharmacy in Hradec Králové Pharmacy Background: Protective effect of resveratrol is shown in many experimental models of cholestasis, but its effect on bile production in healthy individuals has not been studied yet. As the use of resveratrol is frequent in population, the aim of this thesis was to investigate the effect of resveratrol on the bile flow in healthy animals and the clarification of the mechanism of this effect. Methods: Wistar rats (n = 6, in each group, weighing 280 to 320 g) were divided into two groups: control group (Control) and the group of rats administered with resveratrol (10mg/kg/day, p.o.) for 28 days (RES). In vivo clearance study was performed to analyze bile production. Analysis of mRNA and protein expression of the transport proteins was performed by qRT-PCR and Western blot. Results: Resveratrol led to a significant increase in the cumulative bile flow. Analysis of mRNA and protein expression of the transport proteins revealed that bile flow is changed due to posttranscriptional induction of canalicular transporters Bsep and Mrp2. Simultaneously, resveratrol led to induction of Mrp4 efflux protein, expressed at the basolateral membrane of hepatocytes....
