Qualifications and Early Works of Dr. A. S. Paintal

He was among the toppers from his MBBS batch during his studies at the King George Medical College, Lucknow. Everybody expected him to opt for a clinical specialty, but he loved science and research much more than clinical medicine, and against popular advice, he ultimately decided to pursue his MD in Physiology. 

During his MD thesis, he created new electronic instruments by himself to study electrical resistance of the skin, and developed a scoring system to identify Psychotic patients using his techniques. This system later came to be known as Paintal-Index and was widely used by the Psychiatrists. 

He was awarded Rockefeller Fellowship to further study, and he joined a Ph.D. program in electrophysiology at Edinburgh. Once again he built his own electronic equipment to study and also devised a new dissection technique to study deep nerve fibers that supply lungs and heart. 

Dr. A. S. Paintal's Professional Success

Dr. Paintal ultimately succeeded at building a new method for the identification of the terminal portion of a single nerve fiber called "receptor" and describing its features. This method of identifying and studying receptors helped him to find multiple breakthroughs in medical science and provided answers to many unanswered questions of human physiology. 

Using this method, he discovered the "J" receptors in the lungs, "Atrial-B" receptors and "Ventricular Pressure" receptors in the heart, "Gastric-stretch" receptors in the stomach, "Mucosal-Mechano" receptors in the intestines, and "Pressure-Pain" receptors in the muscles.

Positions and Awards Held by Dr. A. S. Paintal

These discoveries and his various other studies about other nerve fibers and receptors earned him an unparalleled reputation as a scientist across the globe, and even beyond the confines of physiology and the medical community. He was recognized as a distinguished scientist and was elected as the President of the Indian National Science Academy and Indian Science Congress Association. He also founded the Society of Scientific Values, a body aimed at promoting ethics and integrity in science, among the first of its kind in the world.

He held high administrative and leadership positions during his journey. Some of those were the Director of VP Chest Institute, New Delhi, The principal of University College of Medical Sciences, New Delhi, and the Director-General of Indian Council of Medical Research, 

In coordination with Govt of India, he founded a department at VPCI to investigate breathlessness and respiratory problems in soldiers posted at high altitudes. He holds the distinction of holding the Padma Vibhushan award, India's second-highest civilian award for rendering exceptional and distinguished service to society. He remains the only non-clinical doctor among the 10 odd medical doctors who have received this honor. Besides Padma Vibhushan, he was bestowed with multiple international and national awards, fellowships, and honorary degrees.

"Perfection must be encouraged and rewarded" - A famous quote by Dr. A.S. Paintal.
