Fingerlings and juvenile trout were exposed to 20 mg/L (twice the therapeutic concentration) of ring UL-14C-tosylchloramide sodium (purity 93.7%, specific activity 1.2 uCi/uM) for up to 1 hr and then transferred to fresh water for recovery to assess tissue accumulation and distribution of resulting residues. The temperature of the well water was 11.6 to 12.2 °C. The estimated half-life of para-toluenesulfonamide equivalents in fingerlings was 27.3 hours whereas determined by HPLC the half-life of para-toluenesulfonamide residues in whole-body homogenates was 36.3 hours. The estimated half-life of residues in juvenile fish was 32.6 hours, based on radiometric data, while determined by HPLC the half-life for para-toluenesulfonamide residues in whole body samples was 40.3 hours. Elimination of total tosylchloramide sodium residues from fingerlings and juvenile whole-body homogenates, based on radiometric counts, was rapid but significantly faster from fingerlings (t1/2 of 27.3 hours) than from juveniles (t1/2 of 32.5 hours). ...Tosylchloramide sodium was poorly absorbed form the bath by both fingerling and juvenile trout. No residues of tosylchloramide sodium, only of the primary metabolite para-toluenesulfonamide, were found in any of the fish tissues in this study therefore, all tissue residues determined either by radiometric or by HPLC methods were reported on the basis of equivalent concentrations of para-toluenesulfonamide. The para-toluenesulfonamide equivalents concentration in whole body homogenates after 1 hr, based on radiometric analysis, was 980 ug/kg, a value about 5% of that in the exposure water, in fingerlings. In juveniles, this value was 570 ug/kg or about 3% of the concentration ing the exposure bath. The exposure of para-toluenesulfonamide in whole body homogenates, after 1 hr, based on HPLC analyses was 360 ug/kg in fingerlings and 170 ug/kg in juveniles.|The percutaneous absorption of tosylchloramide sodium was investigated. Five lactating cows were treated twice daily during milking for 8 days. The teats were cleaned before milking with udder tissues dipped in a solution containing 0.5% tosylchloramide and thereafter dipped after milking into the same solution. The solutions containing 0.5% tosylchloramide were freshly prepared every day. Blood samples were taken from the Vena jugularis during the treatment, immediately before the last treatment and 30 minutes, 1, 2, 4, 8, 16, and 24 hours after the last treatment. The samples were tested with a HPLC method where tosylchloramide is hydrolysed into para-toluenesulfonamide before analyzing of the samples. The detection limit of the method was 5 ug/kg of para-toluenesulfonamide and 8 ug/kg for tosylchloramide. No residues of para-toluenesulfonamide could be detected in any blood samples. It is concluded that the absorption of tosylchloramide in blood in negligible after percutaneous application to the teat.

/Immunoglobulin E/ mediation is a possible mechanism of action for induction of environmental or occupational asthma by Chloramine T. /from table/|The major elastase inhibitor of human serum, alpha-1 proteinase inhibitor (A1PI), is susceptible to oxidative inactivation by a variety of agents, including chloramine T. We have examined the effects of chloramine T on the catalytic activity of porcine pancreatic (PPE) and human leukocyte elastase (HLE) and on the elastase inhibitory capacity of hamster, rat, and human serum as well as pure human A1PI. Both PPE and HLE, but not trypsin, were inhibited in a concentration-dependent manner by concentrations of chloramine T >0.1 mM. The abilities of rat and human serum and pure human A1PI to inhibit both PPE and HLE were inhibited in a concentration-dependent manner by chloramine T. In contrast only the ability of hamster serum to inhibit HLE was altered by exposure to chloramine T: inhibition of PPE was not effected. Gel exclusion chromatography disclosed the existence of two major peaks of elastase inhibitory activity in hamster plasma: one, with an approximate molecular weight of 55 K, eluting in the region of A1PI that was sensitive to chloramine T inactivation and one with a molecular weight of approximately 180 K which was chloramine T insensitive. The parenteral administration of chloramine T to hamsters resulted in a modest and transient diminution of the serum HLE inhibitory activity and an equally modest and transient elevation of PPE inhibitory activity.|Treatment of human erythrocyte membranes with active forms of chlorine (... chloramine T) resulted in a concentration-dependent inhibition of the membrane Na(+), K(+)- and Mg(2+)-ATPases. Membrane protein thiol group oxidation was consistent with inactivation of enzymes and preceded oxidation of tryptophan residues and chloramine formation.|The hypothesis that chloramine-T stimulates the basal Na+ efflux in barnacle fibers as the result of the entry of trigger Ca2+ into the myoplasm from the bathing medium was examined in this study. Two reasons for doing so can be given. One is that the oxidant is known to abolish inactivation in sodium and potassium channels. The other is that L-type Ca2+ channels are present in barnacle fibers, and an increase in internal free Ca2+ in these fibers is known to ... (i) Chloramine-T exerts a biphasic effect on the Na+ efflux: inhibition is followed by stimulation, the threshold concentration being 10-5 M. This is also found to be the threshold concentration for shortening of these fibers. ... (vii) The dose-response curve for chloramine-T shows a shift to the left in poisoned fibers. (viii) The magnitude of the rise in light emission depends on the external Ca2+ concentration. A rise fails to take place in the nominal absence of external Ca2+. Taken together, these results support the above hypothesis that chloramine-T causes the entry of trigger Ca2+ into the myoplasm from the outside and provide evidence that stimulation of the Na+ efflux is associated not only with this event but also with a reduced Na+ gradient resulting from inhibition of the membrane Na+/K(+)-ATPase system by the oxidant.|... The effect of chloramine-T on the inactivation of IK1 was examined in guinea-pig ventricular myocytes using the patch-clamp technique. Chloramine-T (2 mM) irreversibly inhibited the time-dependent decay of whole-cell IK1 inactivation. As a result, the negative slope region of the current-voltage (I-V) relationship was abolished. In cell-attached single channel recordings, the number of active channels in the patch decreased with time during the voltage-clamp step to the K+ equilibrium potential (EK) of -100 mV. Chloramine-T prevented this time-dependent decrease in channel number, and ensemble averaged currents exhibited abolishment of time-dependent decay of channel activity at EK -100 mV.

/HUMAN EXPOSURE STUDIES/ The provocation of occupational asthma by aerogenic exposure to commercial chloramine-T solution was described. A 36 year old female cleaner who had never smoked regularly presented with sneezing, bronchial coughing and dyspnea shortly after starting the use of a new disinfectant at work. She cleaned showers and saunas at a municipal indoor swimming pool using chloramine-T (Alinex) in a 10% solution. The disinfectant was sprayed on walls and floors with pressurized water. The temperature at the job was 30 °C and the relative humidity was 50 to 80%. A provocative dose of chloramine-T was used in the testing at 2.0 micrograms. After 15 minutes the patient developed rhinorrhea, coughing, dyspnea and bronchial wheezes. Positive skin prick tests, RAST, bronchial provocation test results, adequate workplace exposure, and the onset of work related asthmatic symptoms confirmed the diagnosis.|/HUMAN EXPOSURE STUDIES/ As a dust in air it is irritating to eyes, causing conjunctivitis, but no serious injury.|/HUMAN EXPOSURE STUDIES/ 7 brewery workers developed asthmatic symptoms after using Chloramine-T powder as sterilizing agent (0.25-2%).
