Gut is retracting the paper by AK Banerjee and TJ Peters, “Experimental non-steroidal anti-inflammatory drug induced enteropathy in the rat—similarities to inflammatory bowel disease and effect of thromboxane synthetase inhibitors” (Gut1990;31:1358–64) and the abstract AK Banerjee, R Sherwood, JA Rennie and TJ Peters, “Sulphasalazine reduces indomethacin induced changes in small intestinal permeability in man” (Gut1990;31:A593) at the request of Dr Banerjee. At the end of November 2000, the General Medical Council found Dr Banerjee guilty of serious professional misconduct and suspended him for 12 months. Both articles were deemed to contain information which was deliberately falsified.
