Abstract: The object of the present invention is to provide a method for evaluating or selecting an agent having preventive or alleviative effects on spots, which method realizes reliable and effective screening of candidate substances of the agent; a method for predicting spot formation; and a method for analyzing the condition of skin spots. The method of the present invention for evaluating or selecting an agent having preventive or alleviative effects on spots, includes evaluating a substance which suppresses a p53 activity, or an expression level of a p53 gene, a p53 target gene or an expression product thereof in an epidermal cell.

Abstract: This invention provides a vasoprotective agent containing a plant or its extract as an effective ingredient. The plant is selected from the group consisting of rosemary, sage, geranium herb, adlai, field horsetail, bitter orange peel, fucus, burdock, dokudami, Japan pepper, Ophiopogon tuber, ginkgo, natsume and dishcloth gourd.

Abstract: An output apparatus for forming output information on the basis of input information inputted from an external apparatus and outputting is constructed by a connector for connecting the output apparatus to the external apparatus so that they can communicate, a memory to store a data group to manage a menu structure for setting an output environment, an internal environment setting unit for setting an output environment on the basis of the data group, a transfer unit for transferring the data group from the memory to the external apparatus through the connector, and an external environment setting unit for setting an output environment onto the external apparatus on the basis of the data group transferred to the external apparatus. An operating method for the internal environment setting unit and an operating method for the external environment setting unit are identical.

Abstract: When a status change of a printer engine occurs, a status change signal is output to an image data output apparatus. In response to input of the status change signal, the image data output apparatus inquires or confirms the printer engine what kind of status change occurs so that processing to compensate for the status change will be subject to image data to be output to the printer engine.

Abstract: A two component-type developer for electrophotography showing improved electrophotographic performances and also free from carrier adhesion (undesirable carrier transfer to the photosensitive member and recording materials) is constituted by using a magnetic carrier of 5-100 .mu.m in particle size.
