solid foods , and liquid foods such as jellies , candies , granule confectionery , tablet confectionery , beverages , yogurts , soups , noodles , rice crackers , japanese - style confectionery , western - style confectionery , frozen desserts , baked pastry , and seasonings , respectively . in addition , as non - food products other than pharmaceuticals , these ingredients can also be provided in forms such as cosmetics or sanitary goods , and luxury goods . examples of quasi drugs , one of these non - food products , include hair restorers and tonics , depilatories , hair dyes , decolorizers , permanent wave agents , bath agents , medicated cosmetics and medicated soaps , medicated toothpastes , refrigerants , underarm deodorants , and talcum powders . the content of at least one of the fish brain and the parts thereof in these non - pharmaceutical products may be selected depending on the intended use and function of the products . it can be selected for example from the range of 0 . 01 wt % or more , preferably 0 . 1 to 70 wt %. regarding cosmetics , various forms of cosmetics such as lotions , creams , powders , and emulsion gels can be prepared by using various solid , semi - solid , or liquid cosmetic bases , and the food intake regulator or the food intake regulator composition in addition to the other active ingredient ( s ) used to obtain the target cosmetic effect . the fish brain and the parts thereof according to the present invention can be added in any step for production of the food intake regulators , pharmaceuticals and quasi drugs . next , the embodiments for carrying out the present invention are described in detail below by using examples , but the invention is not limited to the examples below . ( preparation of brain substances from chum salmon , oncorhynchus keta ) brains were extracted from the heads of chum salmon fishes by treating them carefully so that the brains were not damaged . the brains were rapidly frozen in liquid nitrogen and dried by lyophilization . the lyophilized brain product from the chum salmon fishes were obtained in an amount of 12 mg per one fish . male sd rats ( sprague - dawley , body weight of 275 ± 25 g ) were housed and fed in 45 × 23 × 15 - cm apecr cages , five rats per cage . the rats were acclimated for 1 week or more on a 12 - h light / 12 - h dark cycle at a room temperature of 22 to 24 ° c . and a humidity of 60 to 80 % with free access to food and water before the test . the rats used for the test were fasted for 12 hours overnight before initiation of the test . after fasting , a sample obtained by homogenizing the lyophilized brain product in a 0 . 5 % carboxymethyl cellulose solution was administrated to each of the rats in the treatment group though a stomach tube in the ratio of 500 mg / kg / 5 ml and , then , their food intakes were measured 1 , 2 , 4 , and 6 after administration . in contrast , in the control group , saline was orally administered by force in the same matter as above and their food intakes were measured in the same way . as shown in fig1 , it was confirmed that the fish brain according to the present invention acts to significantly inhibit or suppress food intake . the above components were mixed . a solution prepared by dissolving 30 mg of hydroxypropyl cellulose in ethanol ( 10 weigh % of hydroxypropyl cellulose ) was added to the mixture of the above components and kneaded to obtain particles . the particles were extruded through a screen having the pore size of 0 . 8 mm to obtain granules . after drying the granules , 15 mg of magnesium stearate was added and tablets were obtained by stamping one tablet per 200 mg . the above component was dispersed in 2 ml of a 5 % mannitol aqueous solution and filled in ampules . the ampules were then sealed under the sterile condition . as mentioned above , the effect of the food intake regulator was noted by allowing the rats to take the fish brain . this shows that the fish brain is useful in improving and treating as well as preventing obesity , and that they can be used as pharmaceuticals , quasi drugs , health foods , functional foods , and other products having the above bioactivity
a safe and widely - applicable food intake regulator can be provided by using at least one of a fish brain and parts thereof , which have the activity to regulate suppress food intake .
