A claim by a local doctor over an 'AIDS medicine' led to a controversy with some professors in Andhra university here taking credit of inventing the medicine and attributing plagiarism to the doctor. A medical practitioner Dr Kutikuppala Surya Rao claimed before newsmen on Wednesday that he had invented medicine for AIDS and named it as 'Kutikuppala compound' and it had shown remarkable results when applied on patients suffering from the dreaded disease.
