Pojmom „burned-out tumour“ sa označuje zriedkavá klinická entita, ktorá sa prezentuje spontánnou a kompletnou regresiou testikulárneho nádoru bez predchádzajúcej liečby pri náleze metastáz v retroperitoneu, v mediastíne, v lymfatických uzlinách, v pľúcach alebo v pečeni. Opisujeme prípad 55-ročného pacienta s bolesťami v pravej driekovej oblasti, u ktorého bola CT vyšetrením zistená tumorózna m...

Voltage-dependent charge movements were measured in the rat omohyoid muscle with the three-microelectrode voltage-clamp technique. Contraction was abolished with hypertonic sucrose. The standard (ON-OFF) protocol for eliciting charge movements was to depolarize the fiber from -90 mV to a variable test potential (V) and then repolarize the fiber to -90 mV. The quantity of charge moved saturated ...

The method of multiscale analysis is constructed for dicrete systems of evolution equations for which the problem is that of the far behavior of an input boundary datum. Discrete slow space variables are introduced in a general setting and the related finite differences are constructed. The method is applied to a series of representative examples: the Toda lattice, the nonlinear Klein-Gordon ch...

The in vitro activity of norfloxacin and six other antimicrobial agents was tested against 93 vibrio strains representing the currently described pathogenic Vibrio species. Norfloxacin had excellent activity against all species, with the following MICs for 90% of the strains: 0.016 micrograms/ml for Vibrio cholerae (including tetracycline-resistant V. cholerae O1 strains), 0.25 micrograms/ml fo...

Experimental autoimmune encephalomyelitis (EAE), an experimental model for the study of multiple sclerosis, is an autoimmune disease of the central nervous system that can be induced in a number of species by immunization with myelin basic protein (MBP). MBP-reactive CD4+ T cells, predominantly expressing the V beta 8.2 T cell receptor (TCR), migrate from the peripheral lymphoid organs and init...

Arctigenin was successfully isolated and purified from the crude extract of Saussurea medusa Maxim. by automatic flash preparation chromatography (AFPC). Chromatographic separation was performed with a gradient elution of (A) petroleum ether and (B) acetone. The qualitative analysis was accomplished with thin layer chromatography (TLC) under the following conditions: petroleum etheracetone (5:3...
