Abstract: New uracil derivatives of the general formula: ##STR1## wherein R.sup.1 stands for a hydrogen atom or a grouping of the formula: ##STR2## R.sup.2 for a hydrogen atom, an alkyl group or a phenyl group and R.sup.3 for an alkyl group or a phenyl group, with the proviso that when both R.sup.1 and R.sup.2 stand for a hydrogen atom, R.sup.3 stands for a phenyl group or a straight chain alkyl group with 3.about.11 carbon atoms, that when R.sup.1 stands for a hydrogen atom and R.sup.2 for methyl group, R.sup.3 stands for an alkyl group with at least 2 carbon atoms or a phenyl group, and that when R.sup.1 stands for a hydrogen atom and R.sup.3 for methyl group, R.sup.2 stands for an alkyl group with at least 2 carbon atoms or a phenyl group. These uracil derivatives are prepared by reacting 5-fluorouracil with an .alpha.-haloalkyl carboxylate or with an aldehyde diacylate or by hydrolyzing a 1,3-bis(acyloxymethyl)-5-fluorouracil with an acid or alkali.

Abstract: Disclosed is a cooking utensil capable of cooking food without burning, which is characterized by the fact that the inner side of the bottom plate thereof contains a circular concave at the center thereof, radial rows of concaves disposed outside the circumference of said central circular concave and as many radial rows interposed one each between the adjacent ones of said first radial rows and each consisting of a circular concave and two convexes disposed opposite each other across said circular concave and the bottom side of said bottom plate contains convexes and concaves respectively at positions exactly corresponding to those of concaves and convexes on the inner side.

Abstract: 1-Carbamoyl-5-fluorouracil derivatives represented by the formula ##STR1## wherein R represents alkyl containing 3-8 carbon atoms are effective oral anti-tumor agents with low toxicity.

Abstract: 1-Carbamoyl-5-fluorouracil derivatives represented by the formula ##STR1## wherein R.sub.1 represents methyl, ethyl, phenyl or cyclohexyl and R.sub.2 represents hydrogen or is the same as R.sub.1 are effective anti-metabolites useful in treating lymphatic leukemia L1210, sarcoma 180A and Ehrlich ascites carcinoma in mice.
