the invention will be explained in more detail in the following with the aid of the examples . a 62 - year - old man suffers from chronic rhinosinusitis with clear swelling of the mucus membranes in both maxillary sinuses with retention of secretion on the left , in ethmoid bone cells , sphenoidal sinus , and in the left frontal sinus . labored nasal respiration . for 2 1 / 2 months increasing headaches at the back of the head , no improvement on antibiotic therapy . the treatment with 1 % nct - na took place over a total of 4 weeks , 3 times weekly , and included 12 treatments in all . each time a 10 - ml nct - na solution was applied by means of a nasal catheter ( yamik ) over a period of time of 12 minutes . thereafter the rinsing solution was suctioned off . result of the treatment : already after the second application complete remission of the pains . after 7 treatments strong decline in the formation of secretion , after 9 treatments clearly improved nasal respiration . 33 - year - old patient suffered from chronic rhinosinusitis for ca . 1 year with swelling of the mucus membranes and increased secretion in the nasal cavity and all its adjacent cavities , strong polyposis and loss of the sense of smell . the treatment with 1 % nct - na took place over a total of 4 weeks , 3 times weekly , and included 12 treatments in all . each time a 10 - ml nct - na solution was applied by means of a nasal catheter ( yamik ) over a period of time of 12 minutes . thereafter the rinsing solution was suctioned off . result of the treatment : already after the sixth application a substantial restoration of the sense of smell . at the end of the treatments an unambiguous regression of the polyposis nasi was to be found . a group of 10 patients who suffered from otitis externa with affliction of the auditory canal were treated . for treatment , 12 cm long strips ( tampons by rauscher ) were placed into the external auditory canal . the test group ( 5 persons ) was treated with strips which were saturated with 1 - ml 1 % nct - na , the control group ( 5 persons ) with strips which were saturated with 1 - ml otosporin ( content per ml : 10 , 000 iu polymyxin b sulfate , 3 . 5 mg neomycin as neomycin sulfate , 10 mg hydrocortisone ). the treatment was done over 5 days . the strips were changed daily . result of the treatment : nct - na proved itself well tolerated . the period until healing was 3 days on average for the nct - na group , 5 days in the otosporin group . a group of 25 patients who suffered from ulcus cruris were treated . the treatment was done with swabs which were saturated with an aqueous solution of 1 % nct - na ( test group , 14 patients ) or 1 % chloramine t ( control group , 11 patients ) and applied directly to the ulcers and left there . the treatment was done over 5 - 14 days . the swabs were changed twice daily . result of the treatment : in both groups the symptoms of inflammation could be made to disappear in 5 to 7 days . in the nct - na group significantly less pains occurred after application of the solution .
a fungicidal agent for treating infectious diseases caused by fungi contains n - chlorotaurine or one of its salts in aqueous solution , optionally with customary pharmaceutical additives .
