Abstract: A medical container with an electrolyte solution stored therein is disclosed. It is formed of a resinmade container main body, a base solution compartment, at least one isolated compartment or connected compartment, and an openable portion. The base solution compartment is arranged in the container main body and is filled with the electrolyte solution in a state steamsterilized together with the container main body. The isolated compartment or connected compartment is arranged in the container main body, is isolated from the base solution compartment by an isolation wall interposed therebetween, and is filled with a bicarbonate. The openable portion permits aseptic communication between the base solution compartment and the isolated compartment or connected compartment by an operation from an outside of the container main body at the time of use. The openable portion is formed at at least a part of the isolation wall.

Abstract: In a test piece for the detection of occult blood, obtained by impregnating a substrate with an organic peroxide, a chromogen, a buffer, and a stabilizer, at least one compound selected from the group of compounds represented by the general formula I: ##STR1## wherein, m denotes an integer of the value of 1 to 5, R.sup.1 denotes one member selected from the group consisting of methyl group, lower alkoxy group, halogen atoms, and hydrogen atom, and X denotes one group selected from the group consisting of ##STR2## where, R.sup.2 and R.sup.3 each denote an alkyl group having 1 or 2 carbon atoms, ##STR3## where, m, R.sup.1, R.sup.2, and R.sup.3 are as defined above, R.sup.4 denotes an alkylene group having 1 to 6 carbon atoms, and n is 0 or 1, ##STR4## where, m, R.sup.1, R.sup.4 are as defined above, and ##STR5## where, R.sup.2 and R.sup.3 are as defined above.
