The stricture is cut under visual control using a knife passed through the sheath of a rigid urethroscope. The stricture is usually cut at the 12 o'clock position, taking care not to cut too deeply into the vascular spaces of the corpus spongiosum that surrounds the urethra. It is possible to get lost when trying to cut a way through a very tight stricture, and this is especially true when there are false passages because of previous dilatation attempts. Accordingly, a guidewire should be passed through to the bladder prior to incision of the stricture in order to establish the true lumen of the urethra. Following urethrotomy a catheter should be left in situ for 1-3 days afterwards. A single urethrotomy seems to give a permanent cure of an uncomplicated stricture in about 50% of patients. Success rates are highest when the stricture is sho and when it is present within the bulbar urethra. In contrast, failure rates are highest in long strictures, strictures within the penile urethra and in recurrent strictures. The main complications are infection and bleeding.

First, T cells are activated by foreign antigen to proliferate and differentiate into effector cells only when the antigen is displayed on the surface of antigen-presenting cells in peripheral lymphoid organs. The T cells respond in this manner because the form of antigen they recognize is different from that recognized by B cells. Whereas B cells recognize intact antigen, T cells recognize fragments of protein antigens that have been paly degraded inside the antigen-presenting cell. The peptide fragments are then carried to the surface of the presenting cell on special molecules called MHC proteins, which present the fragments to T cells. T cells don't act as antigen presenting cells.\n\n###Answer: OPTION A IS CORRECT.", "role": "assistant" } ]

However, in many areas resistant S. typhi have appeared and now it is seldom used. Cotrimoxazole in chancroid Corimoxazole for 7 days is a 3rd choice inexpensive alternative to ceftriaxone, erythromycin or iprofloxacin. Cotrimoxazole It is a combination of sulfonamide (sulfamethoxazole) and trime- thoprim in the ratio of 1 :5. Cotrimoxazole was claimed to be more effective than either of its components individually in treating bacterial infections. Because of its associated greater incidence of adverse effects including allergic responses its widespread use has been restricted in many countries to very specific circumstances where its improved efficacy is demonstracted. Uses of Cotrimoxazole Upper and lower respiratory tract infections - Exacerbations of chronic bronchitis - For otitis media and sinusitis. - It should never be used for streptococcal pharyngitis. Urinary tract infections -Uncomplicated cystitis in non pregnant women. Especially valuable for chronic and recurrent cases. - Prostatitis (cotrimoxazole is concentrated in goodamounts in prostate) Pneumocystic carinii pneumonia -Drug of choice next to pentamidine for the treatment and prophylaxis of pneumonias caused by Pneumocystic Jirovecci (commonly seen in imtnunocompromised patients including those suffering from HIV/AIDS). Other conditions where cotrimoxazole finds its use. -Listeria monocytogens infections - Meliodosis - Shigellosis - Traveller's diarrhoeas (E. coli, Campylobacter, Shigella, Y. enterocolitica) - Prophylaxis of cerebral toxoplasmosis - Whipple's disease - Salmonella (typhoid) initially it was responsive but now resistant strains have emerged. - Chancroid According to K.D.T. - Cotrimoxaxole can be used in both chancroid and typhoid.
