The aim of the study was to evaluate the results of epicutaneous patch testing with a standard series of contact allergens in children suspected to have allergic contact dermatitis (ACD), and to compare the results of patch testing between children and adults. Clinical records of children defined as patients aged ≤18 years and adults examined at Department of Dermatology and Venereology, Karlov...
The cholinergic innervation of the compact and reticular parts of the substantia nigra in the rat was investigated by use of highly sensitive retrograde and anterograde tract-tracing methods in combination with choline acetyltransferase immunohistochemistry. The fluorescent tracers True Blue, propidium iodide, or fluorogold were infused preferentially into either nigral subnucleus. Cells positi...
The effect of various concentrations of divalent cations on survival of gonococci in liquid medium was studied. The growth of Neisseria gonorrhoeae was inhibited by manganous chloride in concentrations above 1 X 10(-5)mol/l while the growth of control organisms such as Neisseria meningitidis and Escherichia coli was not inhibited by the same salt even at 1 X 10(-2)mol/l. Copper sulphate, cobalt...
In this study, solvent extraction is applied for extracting nickel from sulfate solutions containing iron and cobalt ions. This process can also be the cleaning of waste increasing solution concentrations after leaching low-grade ores. Di-2-Ethylhexyl phosphoric acid (D2EHPA) was used as an extractant purpose. Effects pH, aqueous/organic (A/O) phase ratio, iron, ion contents on efficiency were ...
Effect of allergens and irritants on levels of natural moisturizing factor and corneocyte morphology
BACKGROUND The irritant sodium lauryl sulfate (SLS) is known to cause a decrease in the stratum corneum level of natural moisturizing factor (NMF), which in itself is associated with changes in corneocyte surface topography. OBJECTIVE To explore this phenomenon in allergic contact dermatitis. METHODS Patch testing was performed on patients with previously positive patch test reactions to po...
Human airway epithelial cells can increase expression of both lactoferrin and ferritin after exposure to catalytically active metal. These proteins transport and store metal, with coordination sites fully complexed, and therefore can diminish the oxidative stress. The intracellular transport of lactoferrin results in a transfer of complexed metal to ferritin, where it is stored in a less reacti...
The dyeing of woolen yarn with eggplant peel, a natural colorant, has been studied. The main coloring component in this natural colorant is anthocyanin, which is an interesting class of dyes in the blue and red area. Eight mordants including alum, copper sulfate, ferrous sulfate, potash alum, nickel chloride, zinc sulfate, tin chloride, and potassium dichromate were used for mordanting the ...
