    Streszczenie polskie: Diklofop, herbicyd z grupy pochodnych kwasu fenoksypropionowego, nie wykazuje właściwości induktorów CYP1A i słabo stymuluje aktywność CYP2B w wątrobie szczura. Natomiast wyniki sugerują, że badany związek hamuje aktywność fenolowej formy UDP-glukuronylotransferazy.

    Streszczenie angielskie: The study was designed to determine whether diclofop, introduced to environment as herbicide, would exert properties of chemical inducers of rat liver monooxygenase system related to CYP1A and CYP2B isozymes. For this purpose, the effect ofdiclofop on 7-etoxyresorufin O-dealkylase and p-nitroanisole O-demethylase activities specific for CYP1A as well as on CYP2B mediated 7-pentoxyresorufin O-dealkylase activity was studied in male Wistar rats. This biochemical method permits to determine whether tested compound belongs to one of two main types of chemical inducers. Diclofop was dosed by gavage for 4 days at 0; 5.6, 11.2 and 56 mg/kg b.w. per day. Treatment of rats with diclofop resulted in significant increase in relative liver weight (RLW), to 19 p.c. and 31 p.c. above the control, respectively. Diclofop administered at the dose of 11.2 and 56 mg/kg b.w. per day induced a 3-fold (p 0.001) and a 5=fold (p 0.001) increase in the metabolism of 7-pentoxyresorufin (CYP2B-mediated reaction), respectively. No effect level for CYP2B induction was 5.6 mg/kg b.w. per day. However, diclofop induced only slight increase in 7-etoxyresorufin 0-dealkylase and did not show any effect on p-nitroanisole 0-demethylase activity (CYP1A-mediated reactions). The results revealed that diclofop not show the ability to induce CYP1A and moreover it was weak inducer of CYP2B isozymes in the liver of male Wistar rats. Diclofop was also examined for its ability to affect the activity of phenol UDP-glucuronosyltransferase in rat liver. The results suggest that diclofop suppressed phenol form of...

    Streszczenie angielskie: Edema, proteinuria, hypertension (EPH-gestosis), most commonly termed as pre-eclampsia, is the most common pregnancy-associated pathological syndrome. It is accompanied by a through remodelling of extracellular matrix in the umbilical cord tissues. It is commonly known that the presence of serum in culture medium storngly stimulates many functions of cells cultured in vitro. It was decided to check how the pre-eclamptic serum affects the fibroblast division in culture. Ki-67 is a protein present in proliferating cells and can be detected during all phases of the cell cycle (G1, S, G2/M) but not in resting (GO) cells. PCNA (proliferating cell nuclear antigen) is an intranuclear polypeptide whose synthesis rate is at its maximum during the S-phase of the cell cycle. The expression of Ki-67 and PCNA was measured by immunocytochemical methods and biosynthesis of DNA was evaluated by [14C]-thymidine incorporation. The activity of pre-eclamptic umbilical cord serum (UC-serum) was found to be distincly lower in comparison to control one. The expression of Ki and PCNA in fibroblast cultures treated wtih pre-eclaptic serum was also distinctly lower. Also the incorporation of [14C]-thymidine to DNA was lower than in the cultures treated with control UC-serum. It may by concluded that pre-eclampsia reduces the mitogenic activity of the umbilical cord serum.

    Streszczenie angielskie: Pre-eclampsia, the most common pregnancy associated syndrome, is connected with remodelling of extracellular matrix of the ubilical cord tissues. Since the fibroblast growth factor (FGF) is known to be a stimulator of collagen and glycosaminoglycan biosynthesis, one may expect that it plays an improtant role in such a remodelling. Studies performed on the umbilical cords of 10 control and 10 pre-eclamptic newborns demonstrated that both the umbilical cord arterial wall and Wharton's jelly contain FGF mainly in complexes with the components of different molecular mass. Pre-eclampsia is associted with a decrease of endogenous FGF-binding by soluble high molecular mass components of the umbilical cord. It is suggested that FGF released from these complexes may be actively bound by fibroblasts of the umbilical cord, stimulting them to produce collagen and sulphated glycosaminoglycans.
