Nádorová onemocnění představují druhou nejčastější příčinu úmrtí jak v České republice, tak v dalších členských státech EU. V roce 2010 bylo do Národního onkologického registru ČR (ÚZIS ČR, 2013) nahlášeno 82 606 nových případů maligních nádorů, což představuje nárůst asi 4 % oproti roku 2009 (1). Vzhledem k tomu, že nejčastější příčinou úmrtí v celé Evropě jsou onemocnění kardiovaskulárního systému (344 úmrtí na 100 000 obyvatel, dle Evropského statistického úřadu) (2) a u onkologické terapie jsou známy její kardiotoxické účinky, je nutné se zabývat kardioprotektivními technikami a vylepšením současné protinádorové terapie. V tomto přehledovém článku se věnujeme kardiotoxickým účinkům hlavních skupin cytostatických léčiv a potencionálním metodám snížení těchto nežádoucích efektů protinádorové terapie., Cancer represents the second most frequent cause of mortality in the Czech Republic as well as in all other EU member countries. In 2010, there were 82 606 new cases of malignant tumours reported to National oncology registry of the Czech Republic, which means about 4 % increase as compared to 2009. Taking into account that cardiovascular diseases are foremost reason of death in European countries and cardiotoxicity of chemotherapy is well known, there is a need to search for new cardioprotective techniques and improvements of actual anti-tumour protocols. This review focuses on cardiotoxic effects of main groups of cytostatic drugs and on potential methods decreasing these adverse side effects., David Dufek, Tibor Stračina, Marie Nováková, and Literatura
Gastropathy is one of the most common diseases of the human gastrointestinal tract. Apart from its consequences in the stomach, it is also manifested in other parts of the digestive tract, particularly in the duodenum. The aim of this pilot study was to verify on animal model the empirically observed alleviation of gastropathy symptoms in patients who underwent a drinking treatment of Vincentka natural mineral water during their spa treatment. Sixteen male Wistar rats were included in the study. The animals were randomly divided into two groups: experimental group (E; n=8) and control group (C; n=8). The experimental protocol consisted of three phases: (1) handling phase (7 days); (2) mineral water (E)/tap water (C) administration (7 days); (3) acute gastritis induction (1 day). Twenty-four hours after the induction of acute gastritis, the animals were sacrificed. The collected tissues (stomach and duodenum) and blood were examined by standard histological microscopy, and by immunohistochemical and biochemical methods. Histopathological analysis revealed significantly reduced damage to the gastric mucosa in the experimental group. Significantly different values of blood plasma antioxidant capacity, oxidative stress parameters and blood plasma biochemical parameters were also found. Based on these results, we conclude that the mineral water Vincentka has a positive impact on development and symptoms of acute gastric ulcers.
