For modern people, memory is increasing in importance in rapidly changing life, and it is becoming a major concern from adolescents with a lot of social learning to old age. Degenerative brain diseases are known to cause memory loss, and oxidative stress has been found to be an important factor in degenerative brain diseases of the central nervous system such as Alzheimer's syndrome, Parkinson's syndrome and Huntington's syndrome.

Recently, with the increase of the elderly population, degenerative brain disease patients such as dementia have increased rapidly, and various efforts have been made to develop effective treatment drugs and improve effective cognitive and learning functions. have. Memory development drugs developed to date include acetylcholine precursors, receptor agonists, and acetylcholine esterase inhibitors. However, there are no treatments yet available to treat the underlying causes of degenerative brain diseases.Available as general treatments are Pfizer's Aricept, Pfizer's Aricept, Novartis's Exelon, and Janssen's. There is Lundbeck's Ebixa (Memantine), an antagonist mechanism of Reminyl and the recently approved NMDA (N-methyl-D-aspartate receptor) from the US FDA. However, acetylcholine degrading inhibitors only improve the decreased cognitive ability and are unable to cure the underlying cause of Alzheimer's disease.

From the results of Example 2, it was analyzed that the hwansam vine extract may have an effect of treating various diseases derived from neuronal abnormalities, the degenerative brain known as hwansam vine extract is a disease derived from neuronal abnormalities. In order to confirm whether the disease has a therapeutic effect, we tried to verify the therapeutic effect of gingival vine extract on animals induced with Parkinson's disease, a type of degenerative brain disease.

Example  3- 1: 6 - OHDA (6- hydroxyldopamine Parkinson's disease-induced experimental group by administration

As experimental animals, 9-week-old male C57BL / 6J mice were used. The mice were allowed to freely consume sterilized feed and water in a breeding facility in a specific pathogen free (SPF) environment where the temperature was maintained at 22-24 ° C., and were maintained while maintaining a 12-hour day and night cycle.

The experimental animal group was divided into a control group administered with 0.5% CMC (carboxy methylcellulose) and an experimental group administered with 500 mg / kg hwan extract. At this time, the number of the control group and the experimental group was performed using 5 and 8 mice, respectively, 0.5% CMC and 500 mg / kg hwansamvine extract administered 6-OHDA that can specifically kill dopaminergic neurons Orally administered three days before the following.

Anesthetized by administering a mixture of ketamine and rompun to the mouse, an experiment was performed, and the dopaminergic cell loss of the black matter region of the brain, which corresponds to the progression of early Parkinson's disease, was lost. To make this, we used a surgical method that injected 6-OHDA directly into the brain. To prevent the destruction of noradrenergic neurons, 25 mg / kg of desipramine was intraperitoneally administered 30 minutes prior to the administration of 6-OHDA, and a total of 6 µg of 6-OHDA was injected into the striatum of the left brain. Injected (brain microinjection coordinates: front and rear +1.3, left and right -1.8, depth -3.6). As above, 6-OHDA was administered directly to the brain, the surgical site was sutured and disinfected, and then the body temperature of the mouse was maintained at 37 ° C. warmer.

After inducing Parkinson's disease through the above surgical method, behavioral tests such as apomorphine-induced rotational test and expression of tyrosin hydrotylase (TH), a dopaminergic neuron specific protein Until the amount level was measured, 0.5% CMC and 500 mg / kg of the Korean Peninsula vine extract were fed to the control group and the experimental group, respectively. At this time, two days after surgery that was difficult to eat food, oral administration of 0.5% CMC and 500 mg / kg hwan extract.

Example  3-2: Behavioral Assessment Using Parkinson's Disease-Induced Animal Model

It is known that the more dopaminergic cell death caused by 6-OHDA, the more the lesions in one brain become, and the number of rotations is increased behaviorally in the experimental animal model. Therefore, 8 days after 6-OHDA administration, in order to evaluate the severity of dyskinesia caused by dopaminergic cell death, mice were injected with 1 mg / kg of apomorphine intraperitoneally and observed asymmetric rotational behavior. .

Specifically, after administration of the apomorphine drug, the rotational behavior was evaluated by measuring the number of times the mouse was rotated clockwise for 1 hour in a cylinder having a diameter of 20 cm (Fig. 3).

Figure 3 is a graph showing the results of apomorphine-induced rotational movement in the Parkinson's disease mouse animal model induced brain dopaminergic neuron-specific cell death with 6-OHDA, according to the treatment of hwangi vine extract. As shown in Figure 3, compared with the control group ingested 0.5% CMC, it was confirmed that the rotational behavior of the experimental animals was significantly reduced in the experimental group intake of 500 mg / kg hwan extract extract.

Example  3-3: Tyrosine Hydroxylase in Parkinson's Disease Induced Animal Model tyrosin  Determination of the amount of hydroxylase (TH) expression

In order to confirm whether dopaminergic neuronal cell death by 6-OHDA is inhibited in mice by administering Hwansam vine extract, 10% after 6-OHDA administration, 0.5% CMC control control group and 500 mg / kg Hwansam vine extract administration group mice In the striatum of the brain, the difference in the expression level of TH, a dopaminergic neuron specific protein, was analyzed by Western blot (FIG. 4).

Figure 4 is a graph showing the results of measuring the expression level of tyrosin hydroxylase (TH), a dopaminergic neuron specific protein according to the treatment of hwansam vine extract. As shown in Figure 4, compared with the control group, it was confirmed that the TH protein expression level of the experimental group fed the hwansamvine extract extract is a high level.

Therefore, it can be seen that dopaminergic neuronal cell death is significantly suppressed due to the administration of hwansamvine extract.

Example  4: Therapeutic Effect of Ring Ginseng Vine Extract on Alzheimer's Disease

The purpose of this study was to verify the efficacy of the extract of the Korean Peninsula ginseng extract on the induction of Alzheimer's disease, a type of degenerative brain disease.

Example  4-1: Experimental Group Production of Alzheimer's Disease Mouse Animal Model

APPSwe and PSEN1 genes, which are genes related to Alzheimer's disease, are overexpressed in the brain of mouse, and the therapeutic effect of ring vine extract is applied to mouse animal model (B6C3-Tg (APPswe / PSEN1dE9) 85DboJ, JAX, 004462) with Alzheimer's disease. Investigate. In the mouse animal model, beta-amyloid deposition is prominently observed in the brain from 6 months of age, and is characterized by Alzheimer's specific cognitive dysfunction, and is maintained at 22 to 24 ° C. in a specific pathogen free (SPF) environment. Sterilized feed and water intake freely in the breeding facility, and was maintained while maintaining a 12-hour day and night cycle.

The experimental animal group was divided into a group of normal (Non-Tg) mice not overexpressing APP / PSEN1 (n = 20) and a group of Alzheimer's diseased mice overexpressing APP / PSEN1 (n = 22). The test was divided into a control group administered with% CMC and an experimental group administered with 500 mg / kg hwan extract. The control and experimental populations of the Alzheimer's diseased mouse group overexpressing APP / PSEN1 were performed using 10 and 12 mice, respectively. At this time, the mouse group was used for 5 months of age mice, and 0.5% CMC and 500 mg / kg of the ginseng vine extract was orally administered daily for 10 weeks.

Example  4-2: new Awareness of things  Novel object recognition test (NORT)

In order to confirm the cognitive ability and memory enhancement effect of the ring vine extract against Alzheimer's cognitive impairment, a novel object recognition test (NORT) was performed. Specifically, 5% CMC and 500 mg / kg hwan extract, as shown in Example 2-4, was administered to each test group for 8 weeks, followed by NORT. On the first training day, the mice were placed in 41.5 cm x 20 cm x 21.5 cm white boxes and allowed to move freely for 10 minutes. After 10 minutes of adaptation as described above, they were returned to the original cage. On the second day, two identical cylindrical wooden blocks were placed on both sides of the box and exposed for 10 minutes to allow the mouse to explore them. After 24 hours, the box was placed with a new cylindrical block (new object) together with the cylindrical block (used object) that was originally seen, and then the movement of the mouse was observed. At this time, the time of touching the block, snoring, or moving toward the block was measured. The time of interest in the cylindrical block (used object) and the search time of interest in the square pillar block (new object) were measured from the total number of times measured for the two blocks (FIG. 7). At this time, the search time is (time to show interest in familiar objects) / (time to show interest in familiar objects + time to show interest in new objects) × 100 and (time to show interest in new objects) / (for used objects). Time of interest + time of interest to a new object) × 100.

FIG. 7 is a graph showing the effect of improving cognitive function and memory in a novel object recognition test (NORT) according to the treatment of gingko vine extract in a mouse animal model of Alzheimer's disease. As shown in FIG. 7, in the case of a non-Tg mouse group that does not overexpress APP / PSEN1, irrespective of the administration of the gingival vine extract, both the new square cylinder block and the cylindrical block familiar object are used. In the untreated control group of Alzheimer's extract mice overexpressing APP / PSEN1, the untreated control group exhibits Alzheimer's cognitive impairment, which significantly reduces the search time for new objects and distinguishes between familiar and new objects. It was confirmed that they did not do well. On the other hand, in the experimental group of round ginseng extract of the Alzheimer's diseased mouse group overexpressing APP / PSEN1, the interest in the new object was much higher than that of the control group of the green ginseng extract of the Alzheimer's disease mouse group overexpressing APP / PSEN1. As a result, it has been confirmed that the distinction between familiar objects and new objects is clear. In addition, the increase in search behavior in these Alzheimer's disease animal mice was found to be similar to that in normal mice.

Therefore, it can be seen that hwansamvine extract is effective in the treatment of Alzheimer's disease, and hwansamvine extract administration group of the non-Tg mouse group not overexpressing APP / PSEN1 is new compared to the untreated control group. By confirming that the object recognition time is increased, it can be seen that the hwansam vine extract also exhibits an improvement in cognitive function and memory.

Example  4-3: Y maze test

A Y-maze test was performed to confirm the spatial perception and memory enhancement effects of the Korean Peninsula vine extract on the loss of spatial perception and memory caused by Alzheimer's disease.

The Y-maze test apparatus is a transparent acrylic plate (width 10). cm, 40 cm in height, 25 cm in height) is composed of a closed maze of Y-shaped, each maze is arranged at a constant angle of 120 ° to each other. The test was conducted for 10 minutes, and each labyrinth was designated as A, B, and C regions, and experimental experiments were started in one region to freely explore the maze. At this time, the number and order of entering each maze was measured to evaluate the change behavior (spontaneous alteration,%) (Fig. 8). At this time, if they entered three different areas sequentially, one point (actual alteration: ABC, BCA, CAB, etc.) was recognized as one point, and if they were not continuously entered, the score was not recognized as a score. Was calculated by the formula: total number of alterations / (total number of entries-2) × 100.

FIG. 8 is a graph showing the effect of improving spatial perception and short-term memory in the Y-maze test of Alzheimer's disease mouse model. As shown in FIG. 8, in the experimental group in which the Hwansam vine extract overexpressed APP / PSEN1 in the Alzheimer's diseased mice over 9 weeks, the Alzheimer's overexpressed mouse in the Alzheimer's diseased mice, compared to the control group untreated with the hwansamvine extract It was confirmed that the behavioral power increased statistically.
