The first group, treated by photodynamic therapy (δ-aminolevulinic acid (ALA), 630-635 nm wavelength), consisted of 48 patients suffering from leukoplakia. The(More)
BACKGROUND Laser-induced fluorescence diagnostics (LIFE) can be used as an imaging system of precancerous and neoplasmatic lesions of oral mucosa. LIFE system utilizes healthy and neoplasmatically changed tissue in autofluorescence, without using any fluorescence substances. Neoplasmatic lesions are visible in pseudo colors, healthy tissue as a shade of(More)
The effect of pulsed magnetic field (PMF) on gravitropic response, endogenous growth and growth in the presence of indole-3-acetic acid (IAA) was studied in coleoptiles of maize (Zea mays L.) seedlings. Medium pH changes, measured simultaneously with growth of coleoptile segments, were also determined. In seedlings grown in the presence of PMF, elongation(More)
