Reflap^® ointment was mixed with other ointments and creams in equal weight. And lg external powder was mixed with 30g Reflap^® ointment. The mixtures in polyethylene airtight vessels were stored at room temperature for two months. Changes of appearance (e. g., color, odor and bleeding), pH level andlysozyme activity were studied.
It was found that the oil phase was slightly separated in the mixture with Elase^® ointment. The surface color of the mixture with Geben^® cream was changed from white to grayishpurple.

Compatibility tests of lysozyme chloride ointment (Reflap^® Ointment) with eleven anti-microbial agents and four disinfectants were carried out. Reflap^® ointment was mixed with other ointments and creams in equal weight. A day's dose of anti-microbial injections and 5 ml disinfectant solutions were, respectively, mixed with 30g Reflap^® ointment. The mixtures in polyethylene airtight vessels were stored at room temperature for two months. Changes of appearance (e. g., color, odor and bleeding), pH level and lysozyme activity were studied.
It was found that the significant reductions of lysozyme activity immediately occured in the cases of the mixture with Chloromycetin^® ointment or Isodime^® gel. The lysozyme activity were reduced with time in the cases of the mixture with Terra-Cortril^® ointment, Fucidin leo^® ointment and Lilacillin^® injection.

Display system for the medication of out-patients in hospital pharmacy is described. The hardware of this system consists of a LED display, which employs light emitting diodes arranged in a matrix, and a personal computer. The screen composition can be designed for free arrangement in accordance with the purpose of use and the contents of information. This system provides a medium to transmit a large amount of various information to patients in a readily understandable form. The utilization of statistical program in this system enabled us to evaluate the data obtained from the medication to out-patients. It is considered that these functions of this system are highly effective in both offering a better service to patients and improving the dispensing work.
