A deficiency of reduced glutathione in erythrocytes of freshly shed blood (1-4) or in erythrocytes exposed to certain chemical compounds (5) has been associated with shorter red cell survival and, in most cases, with the accumulation of oxidation products of hemoglobin, including methemoglobin, sulfhemoglobin, and Heinz bodies. Studies of "primaquine-sensitive" hemolytic disease have emphasized...

blood sulfhemoglobin (s-hb), total haemoglobin and phosphorous (p) level and blood cell count in 33 matches industry workers of azar abhar, who were exposed directly or indirectly to chemical agents used in the factory (subjects), were measured. the results were compared with the result of the same measurement on 14 farm workers of the region (control) and were analysed. in this study the effec...

Sulfhemoglobinemia is a rare disorder characterized by the presence of sulfhemoglobin in the blood. It is typically drug-induced and may cause hypoxia, end-organ damage, and death through oxygen deprivation. We present here a case of non-drug-induced sulfhemoglobinemia in a 7-day-old preterm infant complicated by hemolytic anemia. Microbiota compositional analysis of fecal samples to investigat...

The investigation embodied in this paper was primarily under-taken in an endeavor to determine in what manner H&3 is ‘transported in the blood after inhalation of this gas. That it is trans-ported in the blood in a loosely combined and readily dissociable manner is evident from the fact that, when H&3 is injected into any of the body cavities, it is a&host at once detectable in the expired air ...

The objective of this study was to examine the effects of supplemental rumen-protected vitamin C (VC) on live and carcass-based performance, and antioxidant capacity of cattle consuming varying concentrations of dietary S. Angus-cross steers (n = 120) were blocked by initial BW (341 ± 11 kg) and assigned equally to 1 of 6 treatments, evaluating 3 concentrations of dietary S [0.22%, 0.34%, and 0...

Many different methods have been used to estimate the average life time of the human red blood cell. The different attempts have yielded estimates which range from 5 to 200 days. Estimates have been made by inducing polycythemia and noting the time required for the return to the normal red cell count; this yielded values of 18 to 30 days (1). Determinations of the amount of iron or pigment excr...

The propensity of certain chemicals and drugs to induce hemolytic anemias has been a subject of much interest for almost a century (1-4). The majority of substances so active are aromatic compounds containing amino-, nitro-, or hydroxy groups, although a number of inorganic compounds (e.g., hydroxylamines, nitrates, nitrites and chlorates) are also active (1-4). Such compounds usually cause red...

Twelve Hereford-Angus weanling heifers were used in a split:plot design incorporating a randomized complete block to determine physiological effects of subtoxic concentrations of inorganic sulfate in drinking water. Treatments were tap-water (110 mg/liter sulfate), 1,250 rag/liter sulfate and 2,500 rag/liter surface. The sulfate was added to the tap water as sodium sulfate. The sulfate-waters d...
