Abstract

PROBLEM TO BE SOLVED: To provide a blood-coagulation inhibitor which is applicable to blood examination for all of chemical items, biochemical items and hematological items, is versatile, is excellent in the effect of preventing blood coagulation and is stable and inexpensive by using the inorganic acid salts of magnesium as effective components. SOLUTION: This blood-coagulation inhibitor is formed of the inorganic acid salts of magnesium as effective components and is particularly effective for coagulation prevention of the blood drawn for blood examination. The inorganic acid salts of the magnesium include, for example, magnesium sulfate, magnesium ammonium sulfate, etc., and their hydrate salts, etc. While these inorganic acid salts may be used alone or in combination of >=2 kinds, the magnesium sulfate and its hydrate salt are more particularly preferable in terms of performance and price. The mechanism of the blood-coagulation preventive effect is indefinite and is estimated that the calcium ions in the blood participating the formation of thrombin having an effect of respectively decomposing fibrinogen and converting the same to fibrin and the formation of the fibrin net by the crosslinking of the fibrin are substituted for magnesium ions.

2. Description of the Related Art In recent years, clinical tests have become an indispensable element in diagnosing a disease state and judging a therapeutic effect. The purpose of this clinical test is to test biological functions. (1) A test (physiological test) for directly examining biological information in a living body
And (2) a test (specimen test) in which a part of a biological component such as blood, urine, or tissue is collected and biotransformation is examined. In the latter sample test, the blood test plays a particularly large role. This blood test consists of (1) chemical tests to check electrolytes, pH, etc.
(2) Measurement of chemical components in blood, measurement of infectious diseases, blood types, cancer-related antigens, and the like using immune reactions, and biochemical item tests for testing bacteria, viruses, pathological cells, and ( 3) It can be broadly divided into blood item tests for examining the morphology and number of blood cells, coagulation function, and the like. In order to perform such a blood test, first, the blood of the subject is collected in a blood test container, and in this case, measures must be taken to prevent the collected blood from coagulating before being subjected to the test. It is important. Blood is fluid while circulating in blood vessels, but once it is removed from blood vessels, it loses fluidity, for example, once it is transferred into a test tube. This is because fibrinogen in plasma is converted into fibrin fibrin,
This is because a fibrin network is formed, and the whole blood becomes gel-like and coagulates. Such blood coagulation is initiated when blood coagulation factor XII in plasma contacts a surface such as a solid phase having a negative charge (eg, glass).
That, Factor XII became the adsorbed activated factor XII (XII a) on the surface, which is interposed calcium ions,
Acts on each clotting factor, eventually producing thrombin,
This thrombin degrades fibrinogen to fibrin to a limited extent, and the fibrin is converted to blood coagulation factor XIII (XIII) activated by thrombin and calcium ions.
Crosslinked by a ) to form a fibrin web and blood to coagulate. In order to prevent such coagulation of collected blood, various things have been developed and used so far. For example, ethylenediaminetetraacetic acid metal salt, sodium citrate, sodium heparin, synthetic hirudin, and a sulfonated diene polymer having a weight average molecular weight of 3,000 or more or a salt thereof (Japanese Patent Application Laid-Open No. 8-43377) may be used for blood collection. Known as anticoagulants. However, these anticoagulants can be applied to the examination of some of the three items (chemical items, biochemical items, and blood items), but cannot be applied to the tests of other items. However, they have problems such as being expensive, having unstable performance and being inadequate, and have not always been satisfactory.

[0006] The amount of the anticoagulant of the present invention added to blood is appropriately selected depending on the kind of the inorganic acid salt of magnesium and the desired anticoagulation time.
It is in the range of 50 mg / ml, preferably 2-40 mg / ml.
If the added amount is less than 1 mg / ml, the effect of preventing blood coagulation may not be sufficiently exhibited, and if it exceeds 50 mg / ml, no improvement in the effect is recognized for the amount, but rather an adverse effect on the blood test. May be given. The form of the anticoagulant of the present invention is not particularly limited, and may be in the form of a powder, an aqueous solution or an aqueous suspension contained in an aqueous medium. As the aqueous medium, an aqueous medium that does not disturb the blood test, preferably, physiological saline can be used. Next, the blood collection container of the present invention will be described. The blood collection container of the present invention contains the above inorganic salt of magnesium in a container, and the inorganic salt of magnesium is used as a powder, an aqueous solution or an aqueous suspension. Further, one kind of this inorganic acid salt of magnesium may be used, or two or more kinds thereof may be used in combination. As described above, magnesium sulfate and a hydrate thereof are particularly preferable as described above. Furthermore, as long as the object of the present invention is not impaired, a conventionally known substance having an anticoagulant effect as described above may be appropriately used in combination.
