Abstract: An immunoregulator that is safe and efficiently incorporated into cells along with a production process thereof are provided. Double-stranded RNA derived from lactic acid bacteria, an immunoregulator having for an active ingredient thereof double-stranded RNA derived from lactic acid bacteria, and a process for producing double-stranded RNA derived from lactic acid bacteria are provided. Bacteria cells of a strains of lactic acid bacteria such as genus Tetragenococcus, genus Pediococcus, genus Lactobacillus, genus Streptococcus or genus Leuconostoc are able to produce double-stranded RNA having immunoregulatory action therein.

Abstract: An interferon ? production promoter and a method for producing thereof are provided. The interferon ? production promoter has a culture, a cell or cell components of lactic acid bacteria as an active ingredient thereof. RNA can be used for the cell component. In addition, bacteria belonging to the genus Lactobacillus, Tetragenococcus, Pediococcus or Streptococcus can be used for the lactic acid bacteria. The interferon ? production promoter can be produced by culturing lactic acid bacteria and collecting a culture, a cell or cell components thereof.

Abstract: It is intended to provide an immunomodulator, which has a high safety and can be effectively incorporated into cells, and a method of producing the same. A double-stranded RNA originating in a lactic acid bacterium; an immunomodulator comprising the double-stranded RNA originating in a lactic acid bacterium as the active ingredient; and a method of producing the double-stranded RNA originating in a lactic acid bacterium. Lactic acid bacterial cells belonging to the genus Tetragenococcus, Pediococcus, Lactobacillus, Streptococcus, Leuconostoc, etc. can produce a double-stranded RNA having an immunomodulation effect therein.

Abstract: A functional composition containing as an active ingredient a lactic acid fermented product obtained by fermenting a component of soybean origin using a lactic acid bacterium belonging to the genera Lactobacillus, Leuconostoc, or Pediococcus. It has various activities such as growth hormone secretagogue activity, fatigue accumulation preventing activity, circadian rhythm regulatory activity, reproductive behavior inducing activity, and so forth and is useful as a growth hormone secretagogue, a fatigue accumulation preventing composition, a circadian rhythm regulator, or a reproductive behavior-inducing composition.

Abstract: A transparent solid detergent comprising N-acylglutamic acid salts, characterized in that said salts are the potassium and sodium salts, each having a neutralization degree of between 1.5 and 2.0, said potassium and sodium salts being in a molar ratio of 9:1 to 2:8 and being incorporated in a combined amount of 30 to 70% of the total weight of said detergent. The detergents of the present ingention moisturize with less irritation to skin, etc. They have good storage stability and usabilities and are especially suitable as facial soap.
