Ozonated blood therapy is used in the treatment of several diseases, including superficial infections, burns, dental and intestinal conditions. Except that, the possibility of using ozone to sterilize blood supplies is under promising investigation. However, still little is known regarding the impact of blood ozonation, especially on biologically active serum sphinoglipids. In the present work we sought to investigate the contents of sphingolipids, such as sphingosine, sphingosine-1-phosphate (S-1-P), sphinganine, and ceramide (CER) in the plasma, after immediate and prolonged (1 h) ozonation of human whole blood. For the measurements liquid chromatography hyphenated with the mass spectrometry was applied. We demonstrated that only the content of sphingosine-1-phosphate in the plasma was increased significantly, possibly exerting its beneficial effect for various physiological and clinical events.

This study evaluated the effectiveness of a biosafety cabinet equipped with an ozone generator, particularly during the transition periods between the production of cell products. As living cell products cannot undergo sterilization, maintaining an aseptic manufacturing environment is paramount. Raw materials, often derived from human tissues, are frequently contaminated with various resident bacteria, necessitating environmental resets after each process.

p-Phenylenediamines (PPDs) are widely used as antioxidants in numerous rubber products to prevent or delay oxidation and corrosion. However, their derived quinones (PPD-Qs), generated through reactions with ozone, are ubiquitous in the environment and raise significant health and toxicity concerns. This review summarizes the current state of knowledge on environmental distribution and fate, human exposure, and biological toxicity of PPDs and PPD-Qs, and makes recommendations for future research directions.

Bromopropane was introduced commercially as an alternative to ozone-depleting and global warming solvents. The identification of 1-bromopropane neurotoxicity in animal experiments was followed by reports of human cases of 1-bromopropane toxicity. In humans, the most common clinical features of 1-bromopropane neurotoxicity are decreased sensation, weakness in extremities, and walking difficulties.
