A follow-up study was performed to describe characteristic physiological alterations by means of computer tomography, direct chemical analysis and histology of the liver, and blood biochemical parameters during conventional force-feeding of Landes geese. 30 birds were exposed to an 18-day long force-feeding. Sampling was performed at the start and during force-feeding (7th, 11th, 14th, 18th days). Computer tomographic data were plotted in 3D histograms, effectively indicating the volumetric development and the fat deposition of the liver. Applying the so-called fat index, a saturation process was found for the hepatic fat content. Histological sections indicated the appearance of microvesicular fat forms in the hepatocyte cytoplasm, which first turned to a total fatty infiltration, later changing to a macrovesicular form with progressing inflammation; membrane damage was not visualized. In blood metabolites triglyceride, total and HDL cholesterol and uric acid increased measurably, while creatinine concentration decreased. Alanine aminotransferase, aspartate aminotransferase activities increased strongly, while that of lactate dehydrogenase only slightly. Based on the results of macroscopic and microscopic imaging techniques and blood biochemical parameters, a comprehensive follow-up study was performed, elucidating still unknown processes during force-feeding of geese.

Introduction: The aim of this study is to compare Knodell and HAI scores in patients with wild type and precore/core promoter mutant CHB to see if there is any difference in severity of liver injury between these two types of HBV. Methods: We did percutaneous liver biopsies of 155 CHB patients. 102 (65.8%) of them were infected wild type HBV and the rest 53 (34.2%) were infected with precore/core promoter mutant CHB. Results: 11/53 (20.8%) patients with precore/core promoter mutant CHB had moderate to severe CH (HAI score 8–18). In contrast, moderate to severe CH was seen in 19/102 (18.6%) patients with wild type CHB. Fibrosis score was >2 in 15/53 (28.3%) precore/core promoter mutant CHB as opposed to 20/102 (19.6%) patients with wild type CHB. Conclusion: The study shows that precore/core promoter mutant HBV produces more severe histologic liver disease compared to wild type HBV.

Thyroid function and morphology, liver morphology, some metabolic indices, haematological parameters and growth performance of fattening pigs fed 00-rapeseed meal (00-RPM) were examined. The control group was fed on a standard diet containing 6% sunflower seed meal (SM) during the growing period and 8% during the finishing period. The first experimental group was fed a diet in which SM was replaced by equal (6% and 8%) amounts of 00-RPM. The second experimental group was fed with a higher (8% and 10%) amount of 00-RPM. There were no significant differences between the control and experimental groups in the serum concentrations of triiodothyronine (T3) and thyroxine (T4). Thyroid gland and liver weights were significantly (P < 0.01) higher in both groups fed 00-RPM than in the group fed SM. The epithelium of the thyroid gland was cuboidal or columnar and the follicular area was moderately enlarged in pigs fed 00-RPM. Marked changes in liver histology were not observed. The 00-RPM diet increased (P < 0.01) the serum values of total proteins in the first fattening period. At the end of fattening both groups fed 00-RPM had higher (P < 0.05; P < 0.01) concentrations of plasma glucose than the control group. The inclusion of 10% of 00-RPM during the finishing period increased (P < 0.05) the serum values of insulin. Daily weight gain during the growing and the finishing period was higher (P < 0.05) in the experimental groups than in the control group. The results suggest that 6-10% 00-RPM can be used as a protein source in the diet of fattening pigs without poisonous side effects.

Absztrakt:

Bevezetés: A zsírmáj kialakulhat betegségek, műtétek, gyógyszerek, éhezés vagy túlzott mértékű alkoholfogyasztás következtében, de a helytelen táplálkozást, a zsírbő és rostszegény étkezést tartják az elsődleges oknak. A nem alkoholos zsírmájbetegség a lakosság 20–30%-át érintheti. A táplálkozási eredetű zsírmájat korai stádiumban általában szövődménymentes májkárosodásnak írják le. Célkitűzés: Kutatásaink célja a zsírdús táplálkozás bél–máj tengelyre gyakorolt hatásának a feltérképezése volt. Módszerek: Rutinlaboratóriumi, analitikai és szövettani módszerekkel patkányokban vizsgáltuk a bél és a máj redoxparamétereit, valamint a máj zsírsavösszetételét és elemtartalmát. Eredmények: A máj elzsírosodása során a vérszérumban mérhető májenzim- és metabolitértékek eltérései mellett a redox-homeosztázis mutatóiban is szignifikáns változások igazolódtak. Változás volt kimutatható a májban, a vérben és a belekben. A máj elzsírosodásának folyamata együtt jár a transzmetiláló képesség csökkenésével. Megváltozott a zsírsavösszetétel és a fémion-homeosztázis is a májban. Szövettani vizsgálatoknál a májlobulusok centrális részén a hepatocyták megduzzadtak, bennük zsírcseppek láthatók, piknotikus sejtmagok alakultak ki, ami a zsíros elfajulásra jellemző. A vékony- és vastagbél enterocytái sérültek, helyenként lelökődtek a felszínről, és gyulladásos reakciók figyelhetők meg a nyálkahártyában. Következtetés: Eredményeink alapján leszögezhető, hogy a zsírdús diéta okozta steatosis már korai stádiumban sem tekinthető egyszerűen reverzibilis változásnak, mert a változások kedvezőtlenül befolyásolják az egész szervezet redox-homeosztázisát, és egyben alapját képezhetik súlyos szív- és metabolikus betegségeknek, valamint siettethetik a gastrointestinalis tumorok kialakulását.
