ABSTRACT
Basal cell carcinoma is the most common nonmelanoma skin cancer. Its occurrence in the perianal region is very rare. Awareness of its benign behavior in this region, in contrast to the earlier reports, is vital in its management. Local excision seems to provide adequate control. We are herewith reporting an extremely rare case of a 69-year-old male with basal cell carcinoma treated adequately with local excision.
ABSTRACT
A new spectrophotometric method for the determination of carbosulfan and propoxur is described, based on coupling their hydrolysis products with diazotized 2-aminobenzophenone to give orange species having an absorption maximum at 465 and 475 nm respectively. Beer's law is obeyed from 0.5 to 10 ppm.
ABSTRACT
A spectrophotometric method has been developed for the determination of isoxsuprine hydrochloride and its dosage forms, based on its coupling reaction with diazotized sulphanilic acid. The yellow chromophore has an absorption maximum at 440 nm. Beer's law holds over the range 0.8-8 mu/ml in the final solution.
