Example 2
Aged retired mice (35-45 weeks old, BALB / cAJcl) preliminarily kept for 1 week were ingested 10 mg of ALA hydrochloride per kg of mouse body weight once a day for 7 consecutive days. ALA hydrochloride was adjusted to a concentration of 0.5 g / mL with distilled water and orally administered to mice. After the test, the mouse was dissected, the blood of the mouse was collected, ALA acid dehydrase (ALAD) activity per mL of blood (5-aminolevulinic acid was dimerized, and porphobilinogen, which is one molecule of pyrrole substance (hereinafter referred to as PBG). Activity) and porphobilinogen deaminase (PBGD) activity (activity for converting PBG to hydroxymethylbilane). The path where ALA forms PBG and the path from PBG to hydroxymethylbilane are some of the important paths for heme synthesis. After adding 0.33 mL of distilled water to 0.02 mL of heparinized mouse whole blood, 0.5 M Na-phosphate buffer pH 6.4, 0.05 mL, 0.1 M DTT (containing 1 mM ZnSO 4 ) 05 mL, 0.05 mL of 50 mM ALA hydrochloride was added to make a total volume of 0.5 mL, this was maintained at 37 ° C. for 30 minutes, 0.5 mL of 1M trichloroacetic acid was added, the reaction was stopped, and the Ehrlich reagent was added to the 3000 rpm supernatant. After exactly 10 minutes, the absorbance at 553 nm, which is the characteristic absorption of the compound produced by the reaction of the Ehrlich reagent and PBG, was measured using a spectrophotometer (OD).

計算はALAD活性によって得られる反応産物PBGの分子吸光係数61000を用いて以下のごとく行った。空試料は反応時間0分を用いた(OD0)。 The calculation was performed as follows using the molecular extinction coefficient 61000 of the reaction product PBG obtained by the ALAD activity. An empty sample was used with a reaction time of 0 minutes (OD 0 ).

ALAD活性=1M×(OD-OD0)/61000×2/1000×1/反応試料量mL×1
=32.8×(OD-OD0)/反応試料量(mL)nmolPBG/mL/h
ALAD activity = 1M x (OD-OD 0 ) / 61000 x 2/1000 x 1 / mL of reaction sample x 1
= 32.8 × (OD-OD 0 ) / reaction sample volume (mL) nmolPBG / mL / h

またPBGD活性は以下の通り測定した。ヘパリン処理したマウスの全血0.02mLに蒸留水を0.38mL加えた後、0.6mM PBG(0.38M Na−phosphate buffer pH7.8を含む)を0.05mL加えた後、37℃、30分間保持した。5M トリクロロ酢酸(0.8%ヨウ素を含む)を0.05mL加え、反応を停止した後、3000rpm5分間の遠心上清をそのまま蛍光分光光度計にて励起波長405nm、蛍光波長597nmの蛍光強度を測定した。   The PBGD activity was measured as follows. After adding 0.38 mL of distilled water to 0.02 mL of whole blood of heparinized mice, 0.05 mL of 0.6 mM PBG (including 0.38 M Na-phosphate buffer pH 7.8) was added, Hold for 30 minutes. After adding 0.05 mL of 5M trichloroacetic acid (containing 0.8% iodine) to stop the reaction, the fluorescence intensity at an excitation wavelength of 405 nm and a fluorescence wavelength of 597 nm was directly measured using a centrifugal supernatant at 3000 rpm for 5 minutes. did.

計算はPBGD活性によって得られるウロポルフィリノーゲン1型異性体の標準物質を用いて比例計算した。   The calculation was carried out in proportion using a standard substance of uroporphyrinogen type 1 isomer obtained by PBGD activity.

すなわち、標準物質0.536nmol URO/mLのときにFU(Em=597nmの蛍光強度)=139
したがって、PBGD活性=0.536/139×0.5/0.01×2×FU/Ht
That is, FU (Em = 597 nm fluorescence intensity) = 139 when the standard substance is 0.536 nmol URO / mL
Therefore, PBGD activity = 0.536 / 139 × 0.5 / 0.01 × 2 × FU / Ht

試験は1区あたり雄のマウス5匹で実施、値は平均値を示した。ALAを処理した区においては、ALAD活性及びPBGD活性が向上していることを確認した。   The test was carried out with 5 male mice per section, and the values showed average values. In the section treated with ALA, it was confirmed that ALAD activity and PBGD activity were improved.

上記のように、ALAを摂取することにより、呼吸電子伝達系の重要な因子であるヘムタンパク質を構成するヘム合成経路の活性(ALAD活性、PBGD活性)を向上させることを見出した。よって、本経路が活性化することにより、動物体内でエネルギー代謝を行うクエン酸回路(TCAサイクル)が活性化され、運動機能が向上したと考えられる。   As described above, it has been found that by ingesting ALA, the activity (ALAD activity, PBGD activity) of the heme synthesis pathway constituting the heme protein, which is an important factor of the respiratory electron transport system, is improved. Therefore, when this pathway is activated, it is considered that the citric acid circuit (TCA cycle) that performs energy metabolism in the animal body is activated and the motor function is improved.
