[The Elektronika MK-52 programmable calculator in processing the results of biochemical studies]

The author reports the use of a new type of an Elektronika MK-52 programmed microcalculator for processing the results of biochemical studies. In contrast to other designs manufactured in this country, it is supplied with semifixed memory that permits storage of programs and data in the calculator after feeding switch off. Two new programs are suggested for estimating chorionic gonadotropin activity and for estimating liposome count in a preparation, and basic operations with the calculator are described as exemplified by these programs. The third program suggested by the author is intended for plotting various calibration straight lines; basing on this program the author demonstrates the use of memory enlargement units manufactured for this calculator.
