Subchronic toxicity of chlorine dioxide and related compounds in drinking water in the nonhuman primate.
Subchronic toxicity of chlorine dioxide and related compounds in drinking water in the nonhuman primate.
****!!!!*** "Subchronic toxicities of ClO2, NaClO2, NaClO3 and NH2Cl were studied in the African Green monkeys (Cercopithecus aethiops). The chemicals were administered in drinking water during 30-60 days subchronic rising dose protocols. The only unexpected and significant toxic effect was elicited by ClO2; this chemical inhibited thyroid metabolism in the animals at a dose of ca. 9.0 mg/kg/day. A statistically significant decrease of serum thyroxine occurred after the fourth week of exposure to 100 mg/l.concentration. The extent of thyroid suppression was dose dependent in each individual monkey, and was reversible after cessation of exposure. NaClO2 and NaClO3 failed to elicit similar effects in doses up to ca. 60 mg/kg/day. Also, NaClO4 or NH2Cl did not cause T-4 suppression in doses of 10 mg/kg/day. The selective thyroid effect of ClO2 was unexplained and it appeared to be paradoxical since ClO2 was rapidly reduced by the oral and gastric secretions to nonoxidizing species (presumably Cl-). No evidence of thyroid effects were detected in the serum of human volunteers who ingested approximately 1 mg/l. of ClO2 in drinking water as a result of routine use in the community water treatment process. Sodium chlorite induced dose-dependent oxidative stress on hematopoesis, causing decreased hemoglobin and red cell count and increased methemoglobin content. At the same time, serum transaminase (SGPT) levels showed significant subclinical elevation. The hematologic effects of NaClO2 rebounded during exposure indicating compensatory hemopoietic activity taking effect during oxidative stress. Sodium chlorate and chloramine did not induce detectable hematologic changes in the animals."

COMPARATIVE SUBCHRONIC TOXICITY STUDIES OF THREE DISINFECTANTS
COMPARATIVE SUBCHRONIC TOXICITY STUDIES OF THREE DISINFECTANTS
In separate subchronic toxicity studies, male and female Sprague-Dawley rats received three water disinfectants in the drinking water for 90 consecutive days. he treatment levels were 25 mg/L, 100 mg/L, 175 mg/L and 250 mg/L for chlorine, and 25 mg/L, 50 mg/L, 100 mg/L and 200 mg/L for both monochloramine and chlorine dioxide. ontrols received carbonated (ph buffered) drinking water. ater consumption for all three compounds decreased in a dose-related fashion with increasing concentration of disinfectant, most likely due to unpalatability. one of the disinfectants caused premature deaths in...

Free radicals: How do they affect the body?
Free radicals are unstable atoms that can cause damage to cells and lead to illnesses and the aging process. Exactly what impact do they have on the body? This MNT Knowledge Center article look at the free radicals and how antioxidants interact with them, as well as what causes them to develop.

{Includes several erroneous statements about CD.} What Does Research Have to Say About HBOT and ASD? Throughout human history, the helping professions – medicine, psychology, education – have operated under many ethical guidelines and codes of conduct. But one singular, defining, and unwavering principle has been, do no harm. Providers of services understand that, fundamentally, we cannot behave in ways that will harm – physically, psychologically, or otherwise – the people whom we serve. This is part of the “DNA” of medical and social services. This

Efficacy and Safety Evaluation of a Chlorine Dioxide Solution
Efficacy and Safety Evaluation of a Chlorine Dioxide Solution
"The efficacy and safety of UC-1 were evaluated. The antimicrobial activity was more than 98.2% reduction when UC-1 concentrations were 5 and 20 ppm for bacteria and fungi, respectively. The half maximal inhibitory concentrations (IC50) of H1N1, influenza virus B/TW/71718/04, and EV71 were 84.65 ± 0.64, 95.91 ± 11.61, and 46.39 ± 1.97 ppm, respectively. A 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) test revealed that the cell viability of mouse lung fibroblast L929 cells was 93.7% at a 200 ppm UC-1 concentration that is over that anticipated in routine use. Moreover, 50 ppm UC-1 showed no significant symptoms in a rabbit ocular irritation test. In an inhalation toxicity test, treatment with 20 ppm UC-1 for 24 h showed no abnormality and no mortality in clinical symptoms and normal functioning of the lung and other organs. A ClO2 concentration of up to 40 ppm in drinking water did not show any toxicity in a subchronic oral toxicity test. Herein, UC-1 showed favorable disinfection activity and a higher safety profile tendency than in previous reports."
