Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composition for preventing or treating a neurological disease containing a Schizandra chinensis extract,

The present invention relates to a pharmaceutical composition for the prevention or treatment of neurological diseases and a health functional food.

The central nervous system consists of neurons and glial cells. The glial cells are the most distributed cells in the brain, accounting for 90% of total brain cells and 50% of the total brain volume. These cells, by themselves, do not produce nerve impulses, but they are known to play a very important role in helping neurons perform their functions and to restore them when brain tissue is damaged. The glial cells are again composed of three kinds of astrocytes, microglia and oligodendrocytes.

Microglia, also called microglia or microglia, are immune cells in the central nervous system (CNS), accounting for 5-10% of total brain cells.

The microglial cells function as a primary defense line in the central nervous system. Microglia are the major intracellular sources of inflammation mediators in the central nervous system. Microglial cells are involved in nerve inflammation by producing nitric oxide (NO), reactive oxygen species (ROS), proinflammatory cytokines and prostaglandins. Activated microglial cells migrate to the damaged neural tissue area and predispose to and destroy microorganisms and cell debris.

However, the role of microglial cells as inflammatory cells is not always beneficial. Activation of uncontrolled microglial cells and persistent excessive neuroinflammation are thought to be the cause of various central nervous system pathologies, including neurodegenerative diseases. In other words, it is known that functionally activated microglial cells produce and secrete inflammatory mediators, resulting in neuronal cell death.

That is, microglial cells, which are immune cells present in the central nervous system, can be activated by various extrinsic and endogenous substances, and activated microglia can be activated by the inflammatory cytokines TNF-α and IL-1β, nitrogen monoxide, prostaglandins, Oxides, and other materials. The production of these substances induces an immune response in the short term, but its excessive production or sustained production induces the death of adjacent neurons, resulting in neurological diseases including neurodegeneration. In addition, neuronal degeneration becomes a vicious circle because the substances released by the dead neurons cause the microglial cells to re-activate. In fact, it has been reported that the activity of microglial cells is related to various neurological diseases such as Alzheimer's disease, Parkinson's disease, Huntington's disease, Lou Gehrig's disease, Creutzfelt-Jakob Disease (CJD) and multiple sclerosis.

Meanwhile, Schisandra chinensis ) is a fruit of Omija tree with a dark red color with a diameter of about 1 cm. It contains ingredients such as sizzindrin, glutamic acid, citrulline, malic acid and citric acid to strengthen the heart and lower the blood pressure, I write. It is known that it strengthens the pulmonary function, and it has the function of chinhae and geodam to help treat cough and thirst. It is also known to put dried fruits in cold water and add honey and sugar to the reddish water to drink it, or to make a bowl or starch piece.

However, only studies on the medicinal properties and efficacy related to Omija fruit have been conducted, and research on other medicinal parts such as Omija leaf and Omiza stem has not been conducted. In particular, considering that the fruit and the physiologically active substance of the leaf or stem are very different, and generally the omija is used only as a fruit, there is a need to research and develop other parts of the omija extract.

Under these circumstances, the present inventors completed the present invention by carrying out research and development on natural extracts effective for nervous system diseases.

Example 2. Induction of 3-nitropropionic acid (3-NP) induction in Huntington's disease model

(1) Preparation of 3-NP induced Huntington's disease animal model

In an animal model of Huntington's disease, Huntington's disease animal models were prepared using 3-NP, a neurotoxic substance, in order to confirm the neuroprotective effect of Schizandra chinensis extract. Specifically, animal models were prepared by preparing male C57BL / 6 mice (Narabiotechnology, Korea) 8-9 weeks after birth and stabilizing for one week. 3-NP (Sigma, USA) was diluted in 100 μl of physiological saline and administered intraperitoneally over 4 times (60, 60, 80 and 80 mg / kg) at intervals of 12 hours.

The criteria for neurological behavior were classified as hind limb hindlimb, hindlimb muscle tension abnormality, activity, thoracic posterior hindlimb posture and postural change, and grades 0, 1 and 2 according to severity in each criterion. FIG. 1 shows the result of classification of Huntington's disease. The higher the score, the greater the neurological behavior symptoms. The survival rate and body weight were checked 24 hours after the last (4th) administration of 3-NP.

(2) Protective effect of Schizandra chinensis extract on neurological behavior and survival rate in animal models of Huntington's disease

(75, 150, and 300 mg / kg) were diluted in physiological saline so that the dose per animal was 100 μl. After 5 days of induction of the Huntington's disease model, .

To confirm the neuroprotective effect of the Schizandra chinensis extract of the present invention on a Huntington's disease animal model, the experimental group was a control group (CON group); 3-NP group and 3-NP group without extract administration; 3-NP + animal model induced, 3-NP + extract (SSC) group; 3-NP, extract group, extract group; The extracts were divided into groups administered orally. In the experiments performed below, the administration of Omija stem extract was applied in the same manner.

After 24 hours of the last (4th) administration of 3-NP, the efficacy of the Schizandra chinensis extract against behavioral changes was verified using the criteria above for neurological behavior.

The results are shown in Fig. 2A. As shown in FIG. 2 A, the behavioral symptom of the 3-NP group was 8.8 ± 0.64, but the behavioral symptoms in the 3-NP + extract group were decreased dependently on the dose of the extract compared with that of the 3-NP group Especially in the group treated with 300 mg / kg. That is, 7.8 ± 0.55 in the 75 mg / kg extract group, 6.5 ± 0.86 in the 150 mg / kg group and 4.3 ± 0.77 in the 300 mg / kg group.

Further, the change in the survival rate was confirmed, and the results are shown in Fig. 2B. As shown in FIG. 2B, the survival rate of the 3-NP group was 50%, but the survival rate of the 3-NP + extract (SSC) group was significantly higher than that of the 3-NP group. That is, 81.3% in the 75 mg / kg extract group, 81.3% in the 150 mg / kg dose group and 75% in the 300 mg / kg dose group.

The change in body weight was also confirmed, and the results are shown in Fig. 2C. As can be seen in FIG. 2C, the body weight of the 3-NP group was 17 ± 0.43 g, which was significantly lower than that of the CON group, and the body weight of the 3-NP group was significantly increased to 19.4 ± 0.37 g in the 300 mg / kg extract group .

(3) Identification of the protective effect of Schizandra chinensis extract against neuronal cell death in Huntington's disease model

The mice were anesthetized by inhalation with ethyl ether 24 hours after the last (4th) administration of 3-NP, and the animals were anesthetized with phosphate buffer (pH: 4) containing 4% paraformaldehyde 7.4) was perfused through the heart and fixed, and the brain was harvested. The extracted brain was washed twice with phosphate buffered saline (PBS), immersed in 4% PFA and fixed at 4 ° C for one more day. Then, 10, 20 and 30% sucrose solution was added and stored at 4 ° C for 48 hours to prevent freezing damage. Using a freezing insert (Leica Cryostat CM3050S, Germany), the area containing the striatum (striatum) was corona-sectioned to a thickness of 30 μm and stored in PBS or freeze storage solution and stored in the freezer.

  Cresyl violet staining was performed to determine the extent of 3-NP-induced neuronal death in the brain. That is, brain tissue was attached to a slide glass coated with gelatin and dried for 24 hours. The dried tissues were rehydrated with xylene and ethanol, stained with cresyl violet dye, sealed with a permount, and observed with an optical microscope.

The results are shown in Figs. 3A to 3E. Neurons were normally observed in the striae of the CON group (FIG. 3A), but neuronal death was pronounced in the striatum of the 3-NP group (FIG. 3B, dotted line). This neuronal death was markedly reduced in the 3-NP + extract group (SSC) (Fig. 3C-3E).

In order to quantitatively confirm these results, the percentage of brain with lesion indicating 3-NP-induced neuronal cell death was confirmed, and the result is shown in FIG. Kg in the group treated with 75 mg / kg of extract, 0 ± 0% in the group treated with 20 ± 0% and 300 mg / kg in the group treated with 150 mg / kg, 0 ± 0% %.

In addition, the area of a site where neuronal apoptosis occurred in relation to the area of a normal striatum was measured, and the result is shown in FIG. 3G. In the group treated with 75 mg / kg of extract (SSC), 27.3 ± 12.9%, in group treated with 150 mg / kg and 9.1 ± 5.8% in group 3-NP, 28 ± 7.6% Respectively.

In addition, Western blot experiments were performed to confirm the protective effect of 3-NP-induced neuronal cell death on the main protein levels of neurons. The mice were anesthetized with ethyl ether 24 hours after the last (4th) injection of 3-NP and the striatum of the cerebrum was extracted and the protein lysis buffer (50 mM Tris-cl, pH 7.5, 150 mM Nacl, 1% Triton X-100, 10% glycerol, and protease inhibitor mixture). Proteins of each individual were quantitated using Bradford (Bio-Rad, USA) method using bovine serum albumin (Sigma, USA) and then 30 μg of protein was resuspended in 10% SDS- PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) and transferred to a PVDF (polyvinylidene difluoride) membrane. PVDF membranes were blocked for 1 hour in TBS-T (Tris-buffered saline, 20 mM Tris, pH 7.4, 0.1% Tween 20 and 150 mM NaCl) with 5% nonfat dry milk. After washing with TBS-T, β-Ⅲ-tubulin, a neurotrophic factor, was used as a neuron marker. β-Ⅲ-tubulin (Sigma, USA) was diluted 1: 2,000, reacted at 4 ° C for one day, washed three times for 10 minutes with TBS-T and reacted with secondary antibody for 1 hour at room temperature. After the secondary antibody reaction, the cells were washed in TBS-T and the bands were identified and quantified using an ECL system (Amersham Pharmacia Biotechnology, USA).

  The results are shown in H and I in Fig. The protein expression of β-III-tubulin was consistent with the results of cresyl violet staining. It was confirmed that the expression of β-III-tubulin was increased by the administration of the extract.

3-NP was finally administered (fourth time), and after 24 hours, the mice were anesthetized by inhalation with ethyl ether and the cerebrum was extracted. The extracted cerebrum was frozen using an OCT compound, and then cut into a 5 ㎛ thick slice using a freezing machine and attached to a slide glass coated with gelatin, completely dried and stored in a freezer. To confirm whether the extract of Omija stem inhibits the decrease of the activity of succinic acid dehydrogenase by 3-NP, the tissue was added to SDH solution (mPMS, NBT, 0.24M disodium succinate stock, Azide / EDTA / PO4 buffer stock solution) Lt; / RTI > After dyeing, the cells were washed and dried. After xylene treatment, the cells were sealed with a perforated microscope and the activity of SDH was quantitated.

The results are shown in Fig. 4A to 4D show the result of staining, and E shows the result of quantification. As shown in FIG. 4, the activity of SDH in the striatum of the 3-NP group was significantly reduced (92.6%) as compared with that of the CON group (100%), ), Respectively (97.9%). The extract alone did not significantly affect SDH activity.

(5) Confirmation of inhibitory effect of Schizandra chinensis extract on microglial cell activation in Huntington's disease animal model

 The mice were anesthetized by the above method, fixed, and frozen sections were prepared 24 hours after the last (4th) administration of 3-NP, and the Iba- Immunostaining was performed using an antibody against 1 (ionized calcium-binding adapter molecule-1; 1: 2,000, WAKO, Japan).

The results are shown in Fig. As shown in FIGS. 5A to 5H, the degree of immunoreactivity to Iba-1 in the striatum of the 3-NP group was significantly increased compared with that of the CON group, and the 3-NP + extract group (300 mg / kg) Respectively. In addition, the single administration of the extract did not significantly affect the immuno-positivity to Iba-1.

Western blot experiments were also performed and quantified by the method described above to determine whether the extract also affected protein expression on Iba-1.

The results are shown in I to J of Fig. As shown in I to J of Fig. 5, the degree of Iba-1 protein expression was consistent with the result of immunostaining.

(6) Confirmation of inhibitory effect of Omija stem extract on apoptosis in animal model of Huntington's disease

On the 7th day after induction of the animal model, mice were anesthetized with ethyl ether, perfused with 0.1 M phosphate buffer (pH 7.4) containing 4% paraformaldehyde (PFA) The brain was harvested. The extracted brain was washed twice with phosphate buffered saline (PBS), immersed in 4% PFA and fixed at 4 ° C for one more day. Then, 10, 20 and 30% sucrose solution was added and stored at 4 ° C for 48 hours to prevent freezing damage. Using a freezing insert (Leica Cryostat CM3050S, Germany), the sections containing the striatum and substantia nigra were coronal sectioned to a thickness of 30 μm and immersed in PBS or freeze storage solution, Lt; / RTI >

   Striatum and black tissue were immersed in PBS containing 3% hydrogen peroxide for 20 minutes to remove the activity of endogenous peroxidase and washed with PBS. The tissues were immersed in blocking solution (5% normal goat / horse serum, 2% bovine serum albumin, 2% fetal bovine serum and 0.1% Triton X- The cells were reacted with a TH antibody (tyrosine hydroxylase; 1: 1,000; Millipore, USA) at 4 ° C for one day. Tissues were washed with PBS and reacted with secondary antibody (rabbit IgG; 1: 200; Vector, USA) at room temperature for 1 hour. After reaction with the secondary antibody, the cells were washed with PBS, reacted with ABC solution (Avidin Biotin Complex, Vector, USA) for 1 hour at room temperature, finally developed with DAB (diaminobenzidine) And then observed with a microscope.

The results are shown in Figs. 9A to 9J.

CON immunoreactive neurons were clearly observed in the dark part of the CON group, and the average was 147.7 ± 5.8 per tissue section, but the mean value was 83.8 ± 6.4 in the MPTP group and significantly decreased when compared to the CON group. However, TH immunoreactive neurons in the dark part of MPTP + extract group increased depending on the concentration of the extract. That is, 106.7 ± 12.3 in extract 37.5 mg / kg, 124.4 ± 6.5 in 75 mg / kg and 138 ± 6.6 in 150 mg / kg.

Further, the results obtained by normalizing the average intensity per tissue section to 100% and the quantitative values of the TH immunoreactive neuron are shown in K and L in Fig.

When the average intensity per tissue section was normalized to 100%, the TH immunoreactivity was clearly observed in the striae of the CON group, and the mean value was 41.6 ± 0.9% in the MPTP group, Respectively. However, in the striatum of the MPTP + extract group, the TH immunoreactivity was increased depending on the concentration of the extract. That is, 67.3 ± 4.5% in the extract group 37.5 mg / kg, 81.8 ± 2.7 in the 75 mg / kg group and 88.6 ± 2.8% in the 150 mg / kg group. The degree of TH immunoreactivity in the black and streaks of the extract group was in agreement with the normal group.

As previously noted, the quantitative level of TH immunoreactive neurons was confirmed, and it was confirmed that the level of TH immunoreactive neurons increased with the administration of Omija stem extract.
