Medical science and technology have made great strides in recent times. The ethical values amidst the various achievements have to be evaluated as science tends to progress in isolation. In a recent conference of the WHO, in Tokyo, in which I was also privileged to participate representing India, some important decisions were made. Most of the nations were represented and included leading medical scientists and researchers. A declaration on medical ethics which is now known as the 'Tokyo Declaration' has come out as a product of this conference.
