この後ラッ トを 5匹ずつのグループに分け、 一方の グループはコ ン ト ロール群と し、 ァロキサン投与の 24時間後、 4 7時間後および 7 1時間後に採血して、 それぞれ血清中のグルコース濃度を測定した。 また他 方のグループは S C— 2 0 0投与群と し、 ァロキサン 投与の 24時間後および 4 8時間後に 1 0 O mgZkgの S C— 2 0 0をそれぞれ経口投与して、 コン トロール 群と同様にァロキサン投与の 24時間後 (S C— 2 0 0の投与直後) 、 4 7時間後および 7 1時間後に採血 して、 それぞれ血清中のグルコース濃度を測定した。 After this, the rats are divided into groups of 5 The group was a control group, and blood was collected at 24 hours, 47 hours and 71 hours after administration of aroxane, and the serum glucose concentration was measured, respectively. The other group was the SC-200 administration group, and 24 hours and 48 hours after administration of aloxane, 100 mg of SC-200 was orally administered, respectively, in the same manner as the control group. Blood was collected 24 hours after administration of aloxane (immediately after administration of SC-200), 47 hours and 71 hours later, and the glucose concentration in serum was measured.
この結果、 第 1図に示すように、 ァロキサン投与前 のグルコース濃度は平均 1 2 3. 3 mgノ dlであり、 ァ ロキサン投与の 24時間後のグルコース濃度は、 コン トロール群で平均 38 6. 1 g/d\, S C — 2 0 0投 与群で平均 3 7 1. 4 mgZdし ァロキサン投与の 4 7 時間後のグルコース濃度は、 コン トロール群で平均 6 84. 2 mg/dK S C— 2 0 0投与群で平均 5 0 0. 8mg/dl、 ァロキサン投与の 7 1時間後のグルコース 濃度は、 コ ン ト ロール群で平均 6 2 3. 8 mg / d K S C— 2 0 0投与群で平均 4 8 1. 6mgZdlであり、 ァロキサン投与の 4 7時間後および 7 1時間後の S C - 2 0 0投与群のグルコース濃度は、 コン トロール群 のグルコース濃度と比べて有意に低いものであった。  As a result, as shown in Fig. 1, the glucose concentration before administration of aroxane was 123.3 mg / dl on average, and the glucose concentration 24 hours after administration of aroxane was 388.6 on average in the control group. 1 g / d \, SC — 200 In the control group, the average glucose concentration at 37 hours after administration of 71.4 mg Zd was 74.8 mg / dK SC—2 in the control group. The average of 50.8 mg / dl in the 00 group and the average glucose concentration 71 hours after aroxane administration was 62.38 mg / d KSC in the control group, and the average in the 200 group. The glucose concentration in the SC-200-administered group at 47 and 71 hours after administration of aroxane was significantly lower than that in the control group.
また、 ァロキサン投与の 9 6時間後の致死率を調べ たところ、 コン トロール群の致死率が 8 0 %であった のに対して、 S C — 2 0 0投与群の致死率は 2 0 %と 低いものであった。 In addition, when the mortality rate of the control group was 96% after the administration of aroxane, the mortality rate of the control group was 80%, whereas the mortality rate of the control group was 20%. It was low.

The second administration of streptozotocin was performed 10 days after the first administration.
最初のス ト レブトゾトシンの投与後、 ラ ッ トを 5匹 ずつ 4つのグループに分け、 1つのグループはコ ン ト 口一ル群と し、 最初のス ト レプトゾト シンの投与から 7日目、 10日目 (2度目のス ト レブトゾト シンの投 与直後) および 13日目に採血して、 それぞれ血糖値 を測定した。 また他の 3つのグループは、 実施例 1と 同一方法により得た S C— 200を投与する S C— 2 00投与群と し、 S C— 200を 5 mgZkgZ日の割合 で投与する群 (S C— 200の 5tngZkg投与群) と、 3 OmgZkgZ日の割合で投与する群 (3 ( — 200の 30mgZkg投与群) と、 20 OmgZkgZ日の割合で投 与する群 (S C— 200の 200 mgZkg投与群) とに 分けて、 最初のス ト レブトゾト シンの投与の 3日後か ら 1 1日間、 S C— 200を連続経口投与し、 最初の ス ト レブ ト ゾ ト シンの投与から 7日後、 10日後 (2 度目のス ト レブトゾトシンの投与直後) および 1 3日 後に各ラ ッ トから採血して、 それぞれ血清中のグルコ ース濃度を測定した。 After the first administration of streptozotocin, the rats were divided into four groups of 5 animals each, one group consisting of a single oral group, and 7 days after the first administration of streptozotocin, 10 Blood samples were collected on days (immediately after the second administration of streptozotocin) and on day 13, and blood glucose levels were measured. The other three groups were the SC-200 administration group to which SC-200 obtained by the same method as in Example 1 was administered, and the group to which SC-200 was administered at a rate of 5 mgZkgZ day (SC-200 5tngZkg administration group), 3 OmgZkgZ days administration group (3 (-200 30mgZkg administration group), and 20 OmgZkgZ days administration group (SC-200 200mgZkg administration group) 3 days after the first administration of streptozotocin, SC-200 was orally administered continuously for 11 days, and 7 days and 10 days after the first administration of streptozotocin (2 days). Blood was collected from each rat immediately after the first streptozotocin administration) and 13 days later, and the glucose concentration in the serum was measured.

また、 最初のス ト レプトゾトシンの投与から 1 3日 後のグルコース濃度は、 コ ン ト ロール群で平均 4 1 8. 9 mg/dl. S C— 200の 5mgZkg投与群で平均 47 8. 7 mg/dK S C— 200の 30 mgZkg投与群で平 均 352. 4 mg/dU S C— 200の 2· 00 mgZkg投 与群で平均 2 84. 6 mgノ dlであり、 S C — 2 0 0の 3 0 ノ1¾投与群ぉょび3 C — 2 0 0の 2 0 0 nig/ kg 投与群のグルコース濃度は、 コン トロール群のダルコ —ス濃度と比べて有意に低いものであった。 The glucose concentration 13 days after the first administration of streptozotocin was 48.7 mg / dl. On average in the control group and 478.7 mg / dl in the 5 mgZkg administration group of SC-200. An average of 352.4 mg / dU SC-200 in 200 mg Zkg of dKSC-200 The average dose in the control group was 284.6 mg / dl, and the glucose concentration in the SC—200 / 300 group and 3C—200 / 200 nig / kg group was It was significantly lower than that of the trol group.
さらに、 最初のス ト レプトゾトシンの投与から 1 3 日後の各ラッ トから脬臓を摘出し、 ラ ンゲルハンス島 におけるアルデヒ ドーフク シン陽性 細胞の比率 (但 し、 3細胞中の非被覆分泌顆粒の内、 陽性反応を示し た非被覆分泌顆粒の比率) を求めたところ、 表一 1に 示すように、 コン トロール群で 1 0. 2 %、 S C - 2 0 0の 3 0 mgZkg投与群で 1 9. 5 %, S C - 2 0 0 の 2 0 0 mgZkg投与群で 1 7. 5 %であり、 S C — 2 0 0の 3

As described in Example 1 and Example 2, the therapeutic agent for diabetes of the present invention has no effect with the conventional hypoglycemic agent Aloxane diabetic distreptozotocin also shows a hypoglycemic effect against streptozotocin-induced diabetes. As can be inferred from Example 2, the antidiabetic agent of the present invention shows that streptozotocin-induced three-cell inflammation This was probably due to its effect on repairing ^ cells that were disrupted by streptozotocin.
以上説明したように、 本発明の糖尿病治療薬は 3細 胞の炎症の抑制作用および崩壊した ^細胞の修復作用 を有している。  As described above, the therapeutic agent for diabetes of the present invention has an inhibitory action on inflammation of three cells and a repair action on broken ^ cells.
したがって、 本発明を実施することによりィ ンシュ リ ン依存性糖尿病を根本的に治療することができる糖 尿病治療薬を供給することができ、 ィ ンシュ リ ン依存 性糖尿病罹患者の経済的および精神的負担を軽減する ことが可能となる。  Therefore, by carrying out the present invention, it is possible to provide a therapeutic agent for diabetes mellitus capable of fundamentally treating insulin-dependent diabetes mellitus. The mental burden can be reduced.
