We report a case of 25-year-old woman with severe tracheobronchial necrosis caused by chlorine released from a mixture household cleaning agents. She subsequently exposed benzene while she was fixing the seats with benzene containing gum. The case was found interesting with its history, delayed
Reactive airways dysfunction syndrome (RADS) is an asthma-like condition that follows exposure to very high concentrations of an irritant material. We assessed the time-course of pathophysiological alterations in a model of RADS. Sprague-Dawley rats were exposed to 1,500 parts per million (ppm) of
OBJECTIVE
The effects of chlorine dioxide (ClO2), sodium hypochlorite (NaOCl), and hydrogen peroxide (H2O2) on cell death and the cell cycle of human gingival fibroblast (HGF) cells were examined.
METHODS
The inhibition of HGF cell growth was evaluated using a Cell Counting Kit-8. The cell cycle was
Eight patients underwent total gastrectomy for caustic ingestion. Oesophago-jejunostomy was performed in the same surgical session. One patient died from hemorrhage. Only one of the 7 survivors had a benign anastomotic fistula. Five healed without any sequelae, 2 underwent colonoplasty 3 months
A retrospective study of 193 adult patients who ingested liquid chlorine bleach is reported. This figure represents 37 p. 100 of caustic product ingestions treated in the authors' hospital unit, these being attempted suicides in 85 p. 100 of the cases. All patients had oesophagogastric fibroscopy on
BACKGROUND
Recently, a hydrosoluble chlorine composed of sodium salts chlorine e6, chlorine p6, and purpurine-5 has been shown to be a promising photosensitizer in antimicrobial photodynamic therapy (aPDT). The aim of this study is to evaluate the effects of adjunctive application of hydrosoluble
Human neutrophils adherent to simulated biologic surfaces undergo significant activation of the respiratory burst over prolonged periods of time in response to stimulation with the cytokines tumor necrosis factor-alpha (TNF alpha) or tumor necrosis factor-beta (TNF beta) or with the chemotactic
Photodynamic therapy (PDT) induces selective cell death of neoplastic tissue and connecting vasculature by combining photosensitizers with light. Here we clarified the types of cell death induced by PDT in combination with the photosensitizer talaporfin sodium (mono-L-aspartyl chlorine e6, NPe6) in
Cancer anorexia-cachexia syndrome (CACS), which is characterized by progressive weight loss (WL) and anorexia (A), is present in 50% of advanced cancer patients and in 80% of terminally ill cancer patients. One of the most controversial aspects of CACS is its oetiopathogenesis; experimental studies
Previously, we screened a series of arylcarboxylic acid hydrazide derivatives for their ability to induce macrophage tumor necrosis factor alpha (TNF-alpha) production and identified 16 such compounds. In the present study, we evaluated 23 additional arylcarboxylic acid hydrazides and found that
Toxicology and carcinogenesis assessments of chlorinated paraffins (C12, 60% chlorine), a material widely used as a flame retardant and extreme-pressure lubricant, were conducted in male and female F344/N rats and male and female B6C3F1 mice in single-administration, 16-day, 13-week, and 2-year
OBJECTIVE
Photodynamic therapy (PDT) and inhibition of cathepsin B proteases by cystatin (cysteine proteinase inhibitor, CPI) are potential new tumour treatment modalities. We have investigated the efficacy of PDT and CPI alone and in combination on a solid mammary carcinoma transplanted into Wistar
Fourteen substituted 4-anilinoquinazolines have been tested for cytotoxic effect and structure activity relationships. The most active derivatives were substituted by chlorine or bromine group in the aromatic ring, in the pyrimidine ring by morpholine group and in the aniline skeleton by nitro group
Asian shrimp farming industry has experienced massive production losses due to a disease caused by toxins of Vibrio bacteria, known as early mortality syndrome/acute hepatopancreatic necrosis disease (EMS/AHPND) for the last 5 years. The disease can cause up to 100% cumulative pond mortality within
