title: The Comorosan effect: single- and double-blind studies on the urea/urease system.
abstract: Characteristic alterations of enzymatic reaction rates by irradiation of the crystalline substrates for fixed periods with an Hg vapor lamp were reported by Comorosan in 1969. Results of single- and double-blind studies reported here support the validity of the key features of this striking and potentially important phenomenon.
