Summary Thermo-XRD-analysis is applied to identify whether or not the adsorbed organic species penetrates into the interlayer space of the smectites mineral. In this technique an oriented smectite sample is gradually heated to temperatures above the irreversible dehydration of the clay, and after each thermal treatment is diffracted by X-ray at ambient conditions. In the thermal treatment of organo-clays, under air atmosphere at temperatures above 250°C, the organic matter is in part oxidized and charcoal is formed from the organic carbon. In inert atmosphere e.g. under vacuum above 250°C the organic matter is pyrolyzed and besides small molecules, charcoal is formed. If the adsorbed organic compound is located in the interlayer space, the charcoal is formed in that space, preventing the collapse of the clay. A basal spacing of above 1.12 nm suggests that during the adsorption the organic compound penetrated into the interlayer space. Thermo-XRD-analyses of montmorillonite complexes with anilines, fatty acids, alizarinate, protonated Congo red and of complexes of other smectites with acridine orange are described. To obtain information about spacings of the different tactoids that comprise the clay mixture, curve-fitting calculations on the X-ray diffractograms were adapted.

Currently used assays for the quantification of apoptotic cells uptake by phagocytes have several methodological problems. Our assay overcomes some of these problems. As a source of apoptotic cells we used peripheral blood lymphocytes obtained from the patients with chronic lymphoblast leukaemia. Apoptosis was induced by incubating cells with cycloheximide for up to 24 h. The assay was performed in suspension of peripheral blood mononuclear cells. For the visualisation of the phagocytes and phagocyted cells and discrimination of phagocyted from bound apoptotic cells we used Acridine orange/Ethidium bromide double staining. Here we offer a simple test which enables reliable measurement and it can show the difference of phagocytic potential between different individuals

The growth in popularity of Over The Counter (OTC) of medicinal products or other natural sources have taken a very large share of healthcare system therefore it is essential to determine their safety as for as public health is concerned.In this study Maximum Tolerated Dose (MTD) was obtained according to CSGMT protocol presented by the Environmental Mutagen Society of Japan. The positive group received mitomycin C in dose of 0.5 mg/kg. The peripheral blood samples before treatment (zero time) were considered as negative control. The MTD of Hypiron was 12 ml/kg and for Chamomilla was 10 ml/kg. Doses of MTD, 1/2 MTD and 1/4 MTD were considered for test groups. Then blood samples were prepared 48 hours after first administration of drugs and kept on precoated Acridine orange slides. The scoring of micronucleated reticulocytes were carried out per 2000 counted reticulocytes in each slide by fluorescent microscope. The results were statistically analyzed. Results of Hypiran were compared with negative control group and the P value was P > 0.05, but the p value of Chamomilla was P < 0.05. Also, the p value of Hypiran and Chamomilla compared with historical negative control group was less, therefore Chamomilla herbal drog can be classified as equivocul category of genotoxicity and Hypiran did not show genotoxicity.

Bevezetés: A gyulladásos bélbetegségek következménye a citokinek közvetítésével kialakuló súlyos lokális szöveti károsodás. Kutatásunk célja az volt, hogy megvizsgáljuk a trinitro-benzol-szulfonsavval (TNBS) kiváltott kísérletes colitis subacut fázisára jellemző gyulladásos válasz és a morfológiai elváltozások befolyásolhatóságát oralis foszfatidil-kolin (PC) és N-metil-D-aszpartát (NMDA) receptor-antagonista kinurénsav-terápia után. Módszerek: Kísérleteinket Sprague–Dawley-patkányok kontroll-, kezeletlen colitis (ic TNBS), 2%-os PC-vel dúsított táppal kezelt colitis (3 nap előkezelés + 3 nap TNBS indukció utáni kezelés) és a 6. napon kinurénsavval kezelt colitis csoportjain végeztük (n = 7). A gyulladás mértékét a colon-mieloperoxidáz- és a plazma-TNF-α-szintek mérésével jellemeztük. A szöveti károsodást hagyományos szövettani (haematoxylin-eosin) vizsgálattal, valamint in vivo konfokális laser scanning endomikroszkóppal (Optiscan Five1, Australia) vizsgáltuk. Meghatároztuk a microvascularis reakciót (FITC-dextrán-festés) és a nyálkahártya-struktúra változásait (akridin orange-festés) a colitis 6. napján. Eredmények: A kezeletlen colitises állatokban szignifikáns mieloperoxidáz- és TNF-α-emelkedést, valamint az epithelialis struktúra jelentős károsodását figyeltük meg. Mindkét kezelési mód jelentősen csökkentette a gyulladásos markerek szintjét, azonban az epithelialis struktúra megőrzésére csak a PC-előkezelés volt alkalmas: szignifikánsan csökkentette a kapillárisok és kripták károsodását, és növelte a kehelysejtek számát. A kinurénsav-kezelés nem befolyásolta a morfológiai elváltozásokat. Következtetés: Oralis PC-előkezeléssel a gyulladásos reakció csökkenthető a vastagbélben. A kehelysejtek számának növelése révén ez ígéretes lehetőség lehet a gyulladásos bélbetegségek kezelésére.
