          강석용 ( Seok Yong Kang ),박용기 ( Yong Ki Park ) 대한본초학회 2015 大韓本草學會誌 Vol.30 No.3

          Objectives : In this study, we investigated the effects of Agastachis Herba water (AH-W) extract on compound 48/80-induced mast cell degranulation and histamine release in human mast cells and also anti-asthmatic effect of AH-W extract on ovalbumin (OVA)-induced asthma in mice. Methods : Human mast cells, HMC-1 were treated with AH-W extract in the presence or absence of compound 48/80 (C48/80). Mast cell degranulation was observed by microscope, and the histamine release was measured in culture medium by ELISA. For preparation of asthmatic in vivo model, mice were sensitized (0, 7, and 14 days) with OVA and airway challenged (21, 23, 25, 27, and 29 days). AH-W extract at doses of 100 and 300 mg/kg/body weight was orally administered during OVA challenge once per a day. The levels of immunoglobulin (Ig) E, and Th1/Th2 cytokines, IFN-γ and IL-4 were measured in the sera of mice by ELISA. The histopathological change of lung tissues was observed by hematoxylin and eosin (H&E) and Periodic Acid Schiff (PAS) staining. Results : The treatment of AH-W extract significantly decreased the mast cell degranulation and histamine release in C48/80-stimulated HMC-1 cells. In addition, The administration of AH-W extract at does of 100 and 300 mg/kg significantly decreased the serum levels of OVA-specific IgE compared with those of OVA control group. In H&E and PAS staining, AH-W extract inhibited OVA-induced airway inflammation, and inflammatory cells infiltration, and also histopathological damages on lung tissues such as bronchiole epithelial desquamation, goblet cells hyperplasia, and mucin releasing. Conclusions : These results indicate that AH-W extract may improve asthmatic symptoms through mast cell stabilization and inhibiting the lung inflammation in bronchial asthma.

          The root bark of Morus alba L. (Mori Cortex Radidus; MCR) has been traditionally used to reduce heat from the lungs, soothe asthma, and edema and to promote urination. In this study, we investigated the effect of MCR ethanol extract on ovalbumin (OVA)-induced allergic asthma in mice. Methods : Mice were sensitized at day 0, 7 and 14 with 0.2% OVA and then airway challenged at day 21, 23, 25, 27 and 29 to induce allergic asthma. MCR extracts at doses of 50 and 100 ㎎/㎏ body weight (bw) were orally administered during OVA challenge once per a day. The levels of allergic mediators such as histamine, OVA-specific IgE, IFN-γ and IL-4 were measured in the sera of mice by ELISA. The histopathological change of lung tissues was observed with hematoxylin and eosin (H&E) staining. Results : MCR extract significantly decreased not only the serum levels of histamine, OVA-specific IgE, and IL-4 compared with those of OVA control group, but significantly increased the serum level of IFN-γ. In H&E staining, MCR extract inhibited the infiltration of inflammatory cells and bronchiolar damage with epithelial thickening in lung tissues of OVA-induced asthma mice. Conclusions : These results indicate that MCR extract inhibits lung damage by asthma through regulating the allergic immune response, suggesting that MCR may be used as a useful agent for the treatment of allergic asthma.

          Objectives: The root of Peucedanum japonicum Thunberg (Peucedani Japonici Radix; PJR) has been traditionally used as an herbal medicine for the treatment of anti-headache, anti-paralysis, anti-cancer, vascular protection, and blood pressure regulation. In this study, we investigated the anti-allergic effect of PJR water extract on ovalbumin (OVA)-induced allergic asthma in mice. Methods : Mice were sensitized at days 1, 8 and 15 with OVA and airway challenged at days 22, 24, 26, 28, and 30 to induced allergic asthma. PJR-W extract at doses of 100 and 300 ㎎/㎏/body weight (bw) was orally administered during OVA challenge once per a day. The levels of allergic mediators such as immunoglobulin (Ig) E, and Th1/Th2 cytokines (IFN-γ and IL-4) were measured in the sera of mice by ELISA. The histological change of lung tissue was observed with hematoxylin and eosin (H&E) staining. Results : The administration of PJR-W extract significantly decreased the serum levels of IgE, IL-4, and IFN-γ compared with those of OVA control group. In H&E staining, PJR-E extract inhibited OVA-induced airway inflammation and the inflammatory cells infiltration in the peribronchial regions of the lung. Conclusions : These results indicate that PJR-W extract has an anti-inflammatory and anti-allergic effect on allergic response through the down-regulation of allergic mediators, suggesting that this herb may be used as a useful source for the treatment of allergic inflammatory diseases such as asthma.

          Objectives: The root of Codonopsis pilosula (Fr.) Nannf. (Codonopsis Pilosulae Radix) has been traditionally used as a oriental medicine with an anti-thrombotic, antidiabetic, anticancer, and anti-gastric ulcer effects and immunological adjuvant. In this study, we investigated the effect of 70% ethanol extract of Codonopsis Pilosulae Radix (CPR-E) on ovalbumin (OVA)-induced allergic responses in mice. Methods : Mice were sensitized (1, 8, and 15 days) with OVA and airway challenged(22, 24, 26, 28, and 30 days) to induced allergic responses. CPR-E extract at doses of 50 and 100 ㎎/㎏/body weight was orally administered from days 21 to 30 consecutively. The levels of allergic mediators such as histamine, OVA-specific immunoglobulin (Ig) E, and Th1/Th2 cytokines such as IFN-γ and IL-4 were measured in the sera of mice by ELISA. The histological change of lung tissue was observed by hematoxylin and eosin (H&E) staining. Results : CPR-E extract significantly decreased the serum levels of histamine, OVA-specific IgE, and IL-4 compared with those of OVA control group, but significantly increased the serum level of IFN-γ. Based on H&E staining, CPR-E extract inhibited the infiltration of inflammatory cells into lung tissues with histological changes. Conclusions : These results indicate that CPR-E extract has anti-inflammatory and anti-allergic responses through regulating the cytokine balance, suggesting that the extract may be useful for the treatment of allergic inflammatory diseases such as bronchial asthma and allergic rhinitis.

          Objectives: This study was designed to evaluate the anti-diabetic effects of Spargaium stoloniferum Buchanan-Hamilton (Sparganii Rhizoma, SR) extract on diabetic rats. Methods: Diabetes was induced with Sprague-Dawley rats by high fat/high sucrose (HF/HS) diet for 4 weeks and injection of a single low dose of streptozotocin (STZ; 35 mg/kg). SR water extract at 500 mg/kg was orally administrated once a day for 4 weeks. Body weights, food and water intakes and urine volumes were measured. The levels of glucose, insulin, total cholesterol, glutamic oxaloacetic transaminase and glutamic-pyruvic transaminase (GPT) were measured in the sera of rats. Histological changes were observed in pancreas, liver, and kidney tissues by H&E staining. Results: The administration of Sparganii Rhizoma extract at 500 mg/kg in diabetic rats did not shown a significant difference in body weight changes and GPT levels, but showed meaningful changes in an increase of urination volume, and decrease of serum glucose and insulin levels. Total cholesterol and GPT levels were also significantly decreased after SR extract administration in diabetic rats. Furthermore, the abnormal changes of pancreas, liver and kidney were also improved by Sparganii Rhizoma extract administration. Conclusions: These results indicate that SR extract can improve HF/HS-diet and STZ-induced diabetic damages in rats through inhibition of the blood glucose and insulin increase.

          Objectives: To prove the channel-tropism theory in herbology, we investigated the anti-diabetic effect of six herbal plants used for lower wasting-thirst in streptozotocin-induced diabetic rats. Methods: Diabetes was induced in male Sprague-Dawley rats by consecutive injection of streptozotocin (30 mg/kg i.p.) for 5 days. The rats were divided into normal control, diabetic control, and diabetic treatment with Lycii Radicis Cortex (LRC, 300 ㎎/㎏); Corni Fructus (CF, 300 ㎎/㎏); Bombyx Batryticatus (BB, 50 ㎎/㎏); Lycii Fructus (LF, 300 ㎎/㎏); Phellodendri Cortex (PC, 300 ㎎/㎏); Epimedii Herba (EH, 300 ㎎/㎏); and glibenclimide (10 ㎎/㎏) as a reference drug. Herbal extracts or reference drug were administered orally for 28 days. The changes of body weight, food intake and water intake, and serological markers such as blood glucose, serum total cholesterol, triglyceride (TG), blood urea nitrogen (BUN), and creatinine (Cr) were measured. Results: The decrease of body weight and the increase of food and water intake in STZ-induced diabetic rats was improved by the administration of CF and LF. Also, the enhancement of blood glucose and serum total cholesterol, TG, BUN and Cr in STZ-induced diabetic rats was significantly inhibited by the administration of CF, BB, LF and glibenclimide. On the other hand, EH strongly inhibited the increase of BUN and Cr in the sera of STZ-induced diabetic rats. Conclusions: These results suggest that among six herbal medicines used lower emaciation of emaciation-thirst disease, CF, BB, LF and EH show a characteristics including the channel-tropism theory.

          황금 추출물의 신경병증성 통증 유발 흰쥐에 미치는 영향

          황민섭(Min Sub Hwang),강석용(Seok Yong Kang),강안나(An Na Kang),김수진(Su Jin Kim),정효원(Hyo Won Jung),박용기(Yong Ki Park) 한의병리학회 2018 동의생리병리학회지 Vol.32 No.1

          TRPA1 and TRPV1 are members of the TRP superfamily of structurally related, nonselective cation channels. TRPA1 and TRPV1 are often co-expressed in sensory neurons and play an important role in mechanical hyperalgesia and allodynia during neuropathic pain. Scutellariae Radix was reported to possess anti-inflammation properties and similar patterns of therapeutic action against different diseases. also Baicalin(a known principal constituent of Scutellaria Radix) was shown to down-regulate the mRNA expression levels of TRPV1. In this study, we observed the effects of Scutellariae Radix extract(SRE) in neuropathic pain induced SD rats via modulation of TRPV1 and TRPA1. Oral administration of a Scutellaria Radix extract(in doses of 300mg/㎏, SRE(300)) showed a meaningful increase in the withdrawal threshold of mechanical allodynia and showed a meaningful decrease in the expression of c-fos compared to the control group. SRE(100) and SRE(300) showed a meaningful decrease in the expression of TRPV1 level compared to the control group. These results suggest that Scutellariae Radix extract could decrease mechanical allodynia by down-regulate the TRPV1 on the model of neuropathic pain.
