Abstract: In a mobile terminal such as a portable cellular phone that is provided with a dial lock function (operation lock function), the state of the mobile terminal is turned from a dial locked state to a dial unlocked state (state transition 3) if a specific secret number is inputted to the mobile terminal (factor 4), and the state of the mobile terminal is turned from the operation unlocked state to the operation locked state (state transitions 11, 7, 9) if at least one of a folded state of the mobile terminal (factor 12), external device connection to the mobile terminal (factor 8), and a battery charging state of the mobile terminal (factor 10) is detected by the mobile terminal. The user of the mobile terminal is allowed to use the dial lock function (operation lock function) more easily and thereby third party's illegal use of the mobile terminal is prevented more efficiently.

Abstract: A method of treating humans suffering from a nutritional deficiency by administering an orally ingestible nutrient composition comprising a substance obtained by extraction of Paramecium thereby providing nutrition to the body with a resultant invigorating effect on the human body. The preferred compositions contain both the lower molecular weight portion and the higher molecular weight portions which are obtained from the extract of Paramecium. It is particularly preferred to utilize the nutrient composition wherein said extract is combined with a clathrate compound, particularly cyclodextrin.

Abstract: A process for preparing a parenteral solution for treating skin diseases comprising the steps of:(1) freeze-drying an aqueous extract of paramecium to obtain a dry powder P.sub.1,(2) dissolving the dry powder P.sub.1 in water and separating the aqueous solution into a high-molecular-weight portion A and a low-molecular-weight portion B,(3) freeze-drying an aqueous solution of the portion B to obtain a dry powder P.sub.2, and(4) dissolving the dry powder P.sub.2 in an excipient to formulate the parenteral solution.
