Specifically, ovariectomy (OVX) was performed at 7 weeks of age after receiving a 6-week-old female C57BL / 6 mouse for a week of purifying period. Thereafter, the ovariectomized mouse was ligated to the left hind limb (HLI) two-vessel blood vessels (artery, vein) at 8 weeks of age and then the ischemic model was completed. The experiment was carried out at the Korea Institute of Oriental Medicine (17-028), and the breeding and maintenance of experimental animals were conducted at 23 ± 1 ℃ and 50 ± 2 ℃, respectively, 10%, and 12 hours of light cycle, and maintained in an IVC (individually ventilated cage). The soil was diluted with 0.1% CMC (carboxymethyl cellulose) and administered orally at 150 mg / kg or 450 mg / kg / day in the morning. After the establishment of the lower limb ischemic model, the blood flow of the left lower limb was measured using a laser Doppler imaging device for 14 days. The ischemic / non-ischemic ratio was compared with that of the right lower limb, The blood flow rate was determined.

As a result, as shown in FIG. 1, it was confirmed that the blood flow rate immediately after lower limb ischemia was significantly reduced in all the control and experimental groups compared to before ischemia induction (-7 days). On the other hand, it was confirmed that the flow of blood flow was significantly increased after 14 days of induction of lower limb ischemia in the experimental group treated with low concentration / high concentration of extract.

From the above results, it was found that the extract of Sorghum significantly increased blood flow reduced by ischemic insult, and thus can be effectively used for prevention, improvement or treatment of ischemic diseases.

The tissue was cut into a thickness of 5 탆 with paraffin sections, and deparaffinized with xylene. Low concentration of ethanol was used at high concentration and finally water was used in tap water. Was used with the antibody is Abcam anti -CD31 (rabbit polyclonal to CD31) 's, the final staining positive cells (brown color) of, the number of peripheral blood vessel (capillary) for counting a unit area number (mm ²⁾ of the reference Respectively.

As a result, as shown in FIG. 2, peripheral vascularization of the ovariectomized lower limb ischemia model was significantly increased in the case of the treatment with the extract of Sorghum extract, which was found to increase in a concentration-dependent manner.

From the above results, it was found that the extract of Sorghum significantly increases the production of peripheral blood vessels and thus can be effectively used for prevention, improvement or treatment of ischemic diseases.

Example 4. Confirmation of wound healing cytokine expression enhancement of soil extracts

In order to confirm the improvement / therapeutic effect of the extracts on the ischemic diseases, we confirmed the effect of increasing the expression of cytokines in relation to the wound healing of the extracts.

Specifically, the extracts were administered to the animal models subjected to lower limb ischemia after ovariectomy at 150 mg / kg / day and 450 mg / kg / day for 3 weeks, respectively. The serum levels of the CXCL12 and CD54 cytokines Respectively. A kit (Proteome Profiler, Mouse Cytokine Array Panel A, ARY006) from R & D SYSTEMS was used and the expression of each cytokine was determined by spot density after the serum was dispensed.

As a result, as shown in FIG. 3, the amount of CXCL12 and CD54 cytokine expression in the ovariectomized lower limb ischemic model was remarkably increased when treated with the extract of soil extracts, which was found to increase in a concentration-dependent manner.

Specifically, the animal extracts were administered at 150 mg / kg / day and 450 mg / kg / day for 3 weeks to an animal model subjected to lower limb ischemia after ovariectomy. In the animal model, left lower thighs and calf muscles Total RNA was extracted from the affected area. The cytokines (TNF-α, IL-6, and IL-1b) involved in the inflammatory reaction were amplified by PCR using 10 g of the cDNA synthesized by reverse transcription of the RNA as a template.

As a result, as shown in FIG. 4, the expression of TNF-α, IL-6, and IL-1b cytokines in the ovariectomized lower limb ischemia model was significantly decreased when treated with extracts Respectively.

From the above results, it was found that the extract of Sorghum reduces the expression of cytokines causing inflammation, and thus can be effectively used for the prevention, improvement or treatment of ischemic diseases.

Example 6 Confirmation of Vascular Endothelial Cell Movement Promoting Effect of Sorghum Extract

In order to confirm the improvement / therapeutic effect of the extract of the extract on the ischemic diseases, the effect of accelerating the vascular endothelial cell migration of the extract of the extract was confirmed.

Specifically, 3 × 10 ³ cells of vascular endothelial cells (HUVAC) were dispensed into the upper well of the transwell and serum extracts were added to serum-free EGM2 medium , 10 and 100 [mu] g / ml, and the cells were cultured for 6 hours. At this time, as the control group, cells not treated with compound or extract, cells treated with 50 ng / ml VEGF as positive control group 1, and cells treated with 1 nM E ₂ as positive control group 2 were set. The transferred vascular endothelial cells were stained with H & E staining, and the effect of the extract of the present invention on vascular endothelial cell migration was compared with the control group.

Specifically, vascular endothelial cells (HUVAC) were dispensed into a 24-well plate coated with Matrigel as an extracellular matrix (ECM) in a number of 3 × 10 ⁵ . Subsequently, tube formation of vascular endothelial cells was induced at 37 ° C for 24 hours using EGM2 medium containing 1% FBS (fetal bovine serum). After 24 hours, the tubes were observed and photographed with a microscope, and tube forming ability was measured using an Image J program Angiogenesis Analyzer and compared with the control group. At this time, as the control group, cells not treated with compound or extract, cells treated with 50ng / ml VEGF as positive control 1, cells treated with 1pM Vinblastine (Velbe) as positive control 2, As positive control group 3, cells were treated with 1 nM E ₂ .

As a result, as shown in FIG. 6, it was confirmed that the degree of tube formation of vascular endothelial cells was significantly increased in the case of treatment with the extract of the extracts, compared with the control without any treatment, and it was found to be increased in a concentration-dependent manner. In addition, the promoting effect on the tube formation of the extracts of the present invention was superior to Vinblastine even at a low concentration of 1 / / ml, and when treated with 100 / / ml, the effect was similar to that of the positive control E ₂ Respectively.
