โœฆ Synopsis

Effects of irradiation with cobalt-60 y-rays on sterilization, storage and enzymes activity of four kinds of biological enzymatic preparations. namely trypsin. pepsin. amylase and liquid carbohydrase. were investigated.The results showed that these enzymes have different sensitivity to irradiation. amylase being the most sensitiveThe enzyme activity and enzyme effect of amylase were lowered with irradiation dose higher than 7 KGY.With irradiation doses between 7-10 KGY, enzyme activity of trypsin and pepsin were stable.Liquid carbohydrase can be stored more than haIfa year under a natural temperature with a stable enzyme activity without molding.

## Abstract ## Background and Objectives An Er:YAG laser effectively removes dental hard substance, and causes less pain during tooth preparations than highโ€speed drilling. This laser was introduced to eliminate the noise, vibration, pressure, and heat associated with the highโ€speed drilling. Howe
