``I am bent upon proving that I am right. I will carry out xenotransplantations once again,'' Dr Baruah told The Indian Express here today.

The surgeon, who issued an advertisement in the local newspapers here today announcing the reopening of his heart institute and research centre, said apart from `cluster xenotransplantation'' facilities, his expanded hospital would also have ``high quality and low cost'' surgery including open heart surgery, kidney dialysis and research in these areas.

He also claimed that Dr Christian Barnard, who pioneered open heart surgery, would attend a seminar in his institute in April this year, ``which will in a big way boost my efforts to popularise xenotransplantation in the country''.

Asked about his legal battle with the Government of Assam wherein he is accused of flouting theTransplantation of Human Organs Act, 1984, Dr Baruah said it was for the State Government to pursue the matter.

``I am right, and I will win the case. Moreover, I have filed a damage suit for Rs 500 crore against the government, before the National Human Rights Commission. I do not want the monetary compensation. I want to teach the Assam Government a lesson,'' Dr Baruah added.

The surgeon, who has his institute at Sonapur, about 30 km East of Guwahati, was arrested on January 1, 1997, following the death of a patient on whom he had carried out transplantation of a pig's heart. He was released on February 18 the same year, and was placed under house arrest, as he claimed, for about 18 months.

He said he had invested about Rs 25 crore in the project, which has gone up to Rs 35 crore following the revamping. The surgeon has also set up a similar institute at Gurgaon near Delhi, which will be operational from December, Dr Baruah informed.
