Abstract
This report presents the reviewing on the past activities in designing of the experiment, preparing of equipments and operating of experimental procedures of L-6A experiment, titled studies on the effects of microgravity on the ultrastructure and function of cultured mammalian cells. The space shuttle was equipped some different type of the stem for syringes. Therefore, the culture medium could not be completely exchanged. The extension of duration of space flight induced some damage of the cultured cells. However, the aim of the L-6A experiment was roughly accomplished. The present reviewing showed that it will be necessary to develop the complete operation procedure for malfunctions of equipments and the quality control of flight hardwares.
