Opis:
At present, the only active substance of Gentian Violet (GV) is methylrosaniline - a triphenylmethane dye of which amino group contains 2 methyl groups. GV can be used to treat uncomplicated bacterial and/or yeast infections, support antibiotic therapy of more severe infections, but also to protect medical equipment against colonization by microorganisms. In the light of recent studies, there are many new possibilities for GV application. It has been shown to be effective in the treatment of viral infections, some chronic skin diseases and oncology. GV can induce apoptosis of tumor cells among others by elevating caspase 8, inhibiting NADPH oxidases, decreasing mitochondrial thioredoxin 2 or inhibiting STAT3/SOX2 axis. Preclinical and in vitro studies have also demonstrated GV efficacy in the treatment of breast cancer, melanoma tumors and cutaneous T-cell lymphoma. There is no unambiguous evidence indicating the toxicity of GV, whereas its safety has been proven by its long history of use, its inclusion in numerous guidelines and its legal trade and distribution with no specific approval requested in many countries around the world. The article gathers the available knowledge about GV and its potential use in the future.

Opis:
There is growing interest in the activity of sulfur-containing compounds on redox balance in physiological and pathological conditions, considering that some of these compounds have not only antioxidative but also pro-oxidative activities. Aim of this study was to assess possible differences in the effects of various sulfur-containing compounds on redox balance of cardiovascular system in its physiological state and in the early onset of hyperhomocysteinemia. This experimental study divided Wistar albino rats into two groups: saline-treated (control) and DL-homocysteine-treated (experimental group). Rats from experimental group were subjected to subchronic subcutaneous administration of DL-homocysteine at dose of 0.45 μmol/g body weight twice a day for 2 weeks. At the end of this period, rats were sacrificed, and blood samples were collected to be analysed for homocysteine concentration and systemic oxidative stress. Isolated rat hearts were excised and attached to the Langendorff apparatus. To assess the effects of acute administration of L-methionine, L-cysteine, N-acetylcysteine, and sodium hydrogen sulfide, the hearts were perfused individually with each of the mentioned substances at same single dose of 0.5 mmol/l for 5 min. In collected samples of coronary venous effluent oxidative stress biomarkers were determined using spectrophotometry. Total homocysteine level was significantly higher in the experimental group than in the control group, and the effects of applied sulfur-containing compounds were significantly different in experimental and control groups. DL-homocysteine induced considerable changes in functioning of cardiovascular system even before an increase in plasma homocysteine values, and action of sulfur-containing compounds varied depending on the presence of homocysteine.
