  • Objectives This study was carried out to investigate the experimental effects of Lonicerae Caulis and Bee-venom Acupuncture in Yanglingquan (陽陵泉, GB34) that have clinical efficacy in the Rheumatoid Arthritis. Methods Materials of present study are Lonicerae Caulis Extracts (LCE), Bee-Venom Acupuncture (BVP), Sprague-dawley rats (250 g or so, ♂), and various kinds of needing experimental studies. We measured several experimental items of the rats with the arthritis induced by Freund's complete adjuvant (0.2 ml/kg), such as body weight, rate of paw edema, analgesic effect by hot plate method, WBC, TNF-${\alpha}$ cytokine and IL-10 cytokine. Rats were divided into four groups; Normal group that was treated with normal saline 1.0 ml (o.p) and $15{\mu}l/kg$ (GB34) to normal rats, Control group that was treated with normal saline 1.0 ml (o.p) and $15{\mu}l/kg$ (GB34) to pathologic model rats induced by Freund's complete adjuvant 0.2 ml/kg, Experimental group A that was treated with LCE 1.0 ml (o.p) and normal saline $15{\mu}l/kg$ (GB34) to pathologic model rats induced by Freund's complete adjuvant 0.2 ml/kg and Experimental group B that was treated with LCE 1.0 ml (o.p) and BVP $15{\mu}l/kg$ (GB34) to pathologic model rats induced by Freund's complete adjuvant 0.2 ml/kg, and the experiment took over after 28 days. The results were analysed using SPSS for windows 12.0. Results Experimental group A showed the increase in body weight, paw licking times and IL-10 cytokine compared to Control group. Also it was decreased in rate of paw edema, WBC, and TNF-${\alpha}$ cytokine compared with Control group. Experimental group B showed the increase in body weight, paw licking times, and IL-10 cytokine compared to Control group, and showed the decrease in rate of paw edema, WBC and TNF-${\alpha}$ cytokine compared to Control group. Especially TNF-${\alpha}$ cytokine and rate of paw edema were accepted statistical significance compared with Control group. Conclusions It is suggested that Lonicerae Caulis (o.p) and Bee-venom Acupuncture (GB34) can be used in the treatment of rheumatoid arthritis.

  • Background: The ubiquitin-proteasome system (UPS) is an important pathway of proteolysis in pathologic hypertrophic cardiomyocytes. We hypothesize that MG132, a proteasome inhibitor, might prevent hypertrophic cardiomyopathy (CMP) by blocking the UPS. Nuclear factor kappa-light-chain-enhancer of activated B cells ($NF-{\kappa}B$) and androgen receptor (AR) have been reported to be mediators of CMP and heart failure. This study drew upon pathophysiologic studies and the analysis of $NF-{\kappa}B$ and AR to assess the cardioprotective effects of MG132 in a left ventricular hypertrophy (LVH) rat model. Methods: We constructed a transverse aortic constriction (TAC)-induced LVH rat model with 3 groups: sham (TAC-sham, n=10), control (TAC-cont, n=10), and MG132 administration (TAC-MG132, n=10). MG-132 (0.1 mg/kg) was injected for 4 weeks in the TAC-MG132 group. Pathophysiologic evaluations were performed and the expression of AR and $NF-{\kappa}B$ was measured in the left ventricle. Results: Fibrosis was prevalent in the pathologic examination of the TAC-cont model, and it was reduced in the TAC-MG132 group, although not significantly. Less expression of AR, but not $NF-{\kappa}B$, was found in the TAC-MG132 group than in the TAC-cont group (p<0.05). Conclusion: MG-132 was found to suppress AR in the TAC-CMP model by blocking the UPS, which reduced fibrosis. However, $NF-{\kappa}B$ expression levels were not related to UPS function.

  • The researches for tumor and the developments for new anti-tumor medicine are being continuously developed in the oriental as well as the west. The principles therapy of anti-tumor activity was based on knowledge of the method of support the healthy energy and strengthen the body resistance, promote blood circulation to remove blood stasis, clear away heat and toxic materials, dissipate phlegm and disperse the accumulation of evils. But the major clinical features of tumor was to be considered in developing a treatment plan include (1) distinguish between clinical and pathologic staging - acute and chronic, (2) classification of pathologic pattern, and (3) distinction of body situation : for examples asthenia - sthenia etc. It was most important to distinguish between supporting the healthy and eliminating the evil factors and to treat differently at the root and the branch cause of a neoplasm. In clinical study and experimental study, the effects of oriental medicine could be summarized as three that were decreasing toxicity of chemo-therapy, directly suppressing and killing cancerous cell and increasing chemo-effect through preventing metastasis. Improving organic immunity with oriental medicine could be summarized as five that were promoting phagocytosis of macrophage, inducing interferon, promoting formation of immnoglobulin, increasing number of T-cell and promoting transformation of lymphocyte. It is suggested that effective use of immune activating herbs inhibited metastasis and decreased recurrence and then we were able to expect increasing survival rate and improving clinical symptoms and quality of life(QOL) of tumor patients.

  • The side effects of head and neck radiation therapy include mucositis, xerostomia, loss of taste, radiation caries, oral infection, osteoradionecrosis and trismus. When a patient is arranged to begin head & neck radiotherapy, oral pathologic lesions are examined and managed for the prevention of oral complications. The advanced odontogenic infection should be especially controlled before the radiotherapy and the patient must be instructed for proper oral prophylaxis. Generally the more conservative treatments, such as, scaling, restoration, endodontic treatment, are the care of choice and dental extraction is performed in advanced periapical and periodontal pathologic conditions. If the dental extraction should be done, the radiotherapy consequently will be delayed until there is epithelium covering the extraction socket, leaving no exposed bone. The cancer patient with severe emotional stress pray for the early radiation therapy, in spite of possibility of the recurrent odontogenic infectious lesions. So, the authors attempted to do the early radiation therapy by the conservative endodontic drainage and surgical incision & drainage without extraction of the infected teeth, and resulted in relatively good prognosis without the severe side effects of head and neck radiotherapy.

  • The ketogenic diet has been widely used and proved to be effective for intractable epilepsy. Although the mechanisms underlying its antiepileptic effects remain to be proven, there are increasing experimental evidences for its neuroprotective effects along with many researches about expanding use of the diet in other neurologic disorders. The first success was reported in glucose transporter type 1 deficiency syndrome, in which the diet served as an alternative metabolic source. Many neurologic disorders share some of the common pathologic mechanisms such as mitochondrial dysfunction, altered neurotransmitter function and synaptic transmission, or abnormal regulation of reactive oxygen species, and the role of the ketogenic diet has been postulated in these mechanisms. In this article, we introduce an overview about the expanding use and emerging trials of the ketogenic diet in various neurologic disorders excluding intractable epilepsy and provide explanations of the mechanisms in that usage.

  • Platelets serve many biological functions, including a major role in the haemostatic process. But platelets also play a crucial role in the formation of arterial thrombosis, arteriosclerosis and other pathologic processes. Thus, there have been many studies to develop new antiplatelet agents from foods and plants for decades. Inthis study, inhibitory effects of the oriental onion (Allium fistulosum) on platelet aggregation were investigated using platelet rich plasma (PRP). Water extracts of oriental onion was separated into two fractions (Fraction I and Fraction II) by Sephadex G-150 column. Platelet aggregations were inhibited by total water extracts as well as Fraction I and II. IC50 value of Fraction I was much lower than that of Fraction II. Inhibitory effects of total water extracts of oriental onion on ATP release by PRP were also observed.

  • The present review investigates the role of the cytoprotective enzyme heme oxygenase-1 (HO-1) in human diseases and explores strategies for its clinical use. In recent years, there has been a growing evidence, for the beneficial effects of some phytoconstituents via induction of HO-1 expression, contained in commonly used spices, fruits, and herbs, in preventing various pathologic conditions, including cancer, diabetes, and cardiovascular diseases. HO-1 catalyzes the rate-limiting step in heme catabolism to generate ferrous iron, carbon monoxide, and biliverdin. HO-1 is reported to play crucial roles in cellular protection, such as anti-inflammatory, anti-proliferative and anti-apoptotic effects. These evidences indicate that HO-1 may functions as a potential therapeutic target in various human diseases. The article highlights the current status of the development of the HO-1 modulation pathway using dietary phytoconstituents.

  • Corticosteroid (budesonide) nebulizer therapy is commonly performed. Its side effects have been considered as being safe or ignorable. The authors present a case of esophageal candidiasis in a healthy female adolescent who was treated with budesonide nebulizer therapy a few times for a cough during the previous winter season. This child presented with dysphagia and epigastric pain for 1 month. Esophageal endoscopy showed a whitish creamy pseudomembrane and erosions on the esophageal mucosa. Pathologic findings showed numerous candidal hyphae. She did not show any evidence of immunodeficiency, clinically and historically. The esophageal lesion did not resolve naturally. The esophageal lesion completely improved with the antifungal therapy for 2 weeks; the symptoms disappeared, and the patient returned to normal health. It is important that frequent esophageal exposure to topical corticosteroids application can cause unexpected side effects.
