TL;DR: Sodium selenosulfate showed a consistent cytotoxic effect when added to three kinds of leukemia cell lines (HL60, T lymph adenoma, and Daudi) and was obtained by mixing sodium selenite, glutathione, and sodium sulfite at room temperature.
Abstract: The biological profile of sodium selenosulfate, Na(2)SeSO(3), is still largely unknown. The present study found that sodium sulfite reacted with elemental selenium at nanoparticle size already at 37 degrees C to yield sodium selenosulfate. Additionally, selenosulfate was obtained by mixing sodium selenite, glutathione, and sodium sulfite at room temperature. In vitro, sodium selenosulfate killed HepG2 or Caco2 cells, in a dose-dependent fashion, and 12.5 microM fully suppressed their proliferation. In addition, sodium selenosulfate showed a consistent cytotoxic effect when added to three kinds of leukemia cell lines (HL60, T lymph adenoma, and Daudi).

TL;DR: In this paper, a dyeing defect repair agent consisting of a colour stripping agent and a color stripping catalyst is described. And the preparation method employed the following procedures: preparing the color stripping agent: wherein, the organic reducing agent and the inorganic reducing agent basedon the weight percentage are sufficiently and uniformly mixed under the room temperature; preparing the colour stripping catalyst: wherein the alkaline compounds based on the weight percent are dissolved and uniformly mix by using the soft water under room temperature.
Abstract: The invention relates to a dyeing defect repair agent and a preparation method thereof. The dyeing defect repair agent comprises a color stripping agent and a color stripping catalyst and is characterized in that the ingredients of the color stripping agent based on weight percent comprise: 80-95% of an organic reducing agent which is zinc formaldehyde sulfoxylate (Decrolin), thiourea dioxide or leucotrope W; 20-5% of an inorganic reducing agent which is sodium thiosulfate, sodium bisulfite or sodium sulfite; the ingredients of the color stripping catalyst based on weight percent comprise: 5-10% of alkaline compounds which are organic bases comprising triethanolamine or which are inorganic bases comprising sodium carbonate, sodium hydroxide, potassium carbonate or sodium silicate; and soft water as the balance. The preparation method thereof employs the following procedures: preparing the color stripping agent: wherein, the organic reducing agent and the inorganic reducing agent basedon the weight percentage are sufficiently and uniformly mixed under the room temperature; preparing the color stripping catalyst: wherein, the alkaline compounds based on the weight percent are dissolved and uniformly mixed by using the soft water under the room temperature.
