  • Previously, several prenylated flavonoids having a C-8 lavandulyl moiety were found to inhibit cyclooxygenase-1 (COX-1) as well as 5-lipoxygenase (5-LOX), and sophoraflavanone G was the most potent inhibitor against these eicosanoid generating enzymes among the prenylated flavonoids tested. In this investigation, effects of sophoraflavanone G on COX-2 induction from RAW 264.7 cells and in vivo inflammatory response were studied. Sophoraflavanone G inhibited prostaglandin E$_2$(PGE$_2$) production from lipopolysaccharide (LPS)-treated RAW cells by COX-2 down-regulation without significantly affecting COX-2 activity at 1 50 $\mu$M. Other prenylated flavonoids including kuraridin and sanggenon D also down-regulated COX-2 induction at 10-25 $\mu$M, lirhile kurarinone and echinoisoflavanone did not. In addition, sophoraflavanone G shelved in vivo anti-inflammatory activity against mouse croton oil-induced ear edema and rat carrageenan paw edema via oral (2-250mg/kg) or topical administration (10 - 250 $\mu\textrm{g}$/ear). Although the potencies of inhibition were far less than that of a reference drug, prednisolone, this compound showed higher anti-inflammato교 activity when applied topically, suggesting a potential use for several eicosanoid-related skin inflammation such as atopic dermatitis.

  • Ziziphus jujuba (ZJ) fruit is rich in bioactive functional components such as polysaccharides, triterpenoid acid, flavonoids and oleamide. It has been commonly used in the treatment of various diseases including diabetes, digestive disorders, diarrhea, skin infections, liver and urinary diseases. However, its dietary effect on chemoprevention of colon cancer has never been studied. The present study was to evaluate the protective effects of dietary ZJ on colitis-associated colon carcinogenesis in azoxymethane (AOM)-dextran sodium sulphate (DSS)-treated mice. AOM was injected (10 mg/kg b.wt., i.p.) and three cycles of 2% DSS in drinking water for 7 days with 14 days of normal drinking water in-between was administered to induce colitis-associated colon cancer. ZJ fruit was supplemented in feed as 5 and 10%. Dietary ZJ significantly attenuated aberrant crypt foci (ACF) formation thereby decreasing the progression of hyperplasia to dysplasia. In addition, it significantly reduced circulating white blood cells, lymphocytes, neutrophils, monocytes, eosinophils, basophils and platelets compared to colon cancer mice. We conclude that ZJ supplementation delayed the progression of colon cancer from hyperplasia to dysplasia and ultimately adenocarcinoma and cancer. In addition, it decreased circulating tumor-related leucocytes, main regulators of cancer inflammation. Therefore, dietary consumption of ZJ fruit attenuated the formation of ACF and delayed the progression of colon cancer.

  • Prostate cancer is one of the most common non-skin cancers in men. Armeniacae Amarum Semen has traditionally been used for the treatment of inflammation diseases, leprosy, leucoderma, and tumors. Apoptosis, which is also known as programmed cell death, is an important mechanism in cancer treatment.Objectives : We observed whether an aqueous extract of Armeniacae Amarum Semen induces apoptotic cell death in human DU145 prostate cancer cells.Methods : We treated DU145 cells with Armeniacae Amarum Semen extract and investigated characteristics of apoptosis. And investigated whether treated with Armeniacae Amarum Semen extract increased Bax mRNA expression, Bcl-2 mRNA expression, caspase-3 enzyme activity and their protein level.Results : We have shown that Armeniacae Amarum Semen extract can induce apoptotic cell death in human DU145 prostate cancer cells by caspase-3 activation through the down-regulation on Bcl-2 expression and the up-regulation on Bax expression.Conclusions : It can be expected that an aqueous extract of Armeniacae Amarum Semen may offer a valuable means for the treatment of prostate cancers.

  • Purpose: An inverted nipple presents both cosmetic and functional problems. It is a source of repeated irritation and inflammation, and interferes with nursing. In addition, its abnormal appearance may cause psychological distress. With consideration of its underlying pathophysiologic components and severity, a number of techniques have been introduced for correction of this anomaly. The diversity of techniques indicates the lack of a good, sustainable, and durable solution for this quite common problem. We report our method as an alternative solution for correcting of the inverted nipple. Methods: From August 2003 to November 2007, 273 nipples in 147 patients were treated. 126 patients had bilateral inverted nipples. Patient age at the operation ranged from 21 to 63 years(mean age, 34 years). All nipples were congenital anomaly. 45 nipples were graded as grade I, 179 nipples as II, and 49 nipples as III. In the our study, we made some modification to the classic purse-string suture: (1) twice purse-string suture: (2) excision of diamond-shaped skin at the nipple neck: (3) buried suture of the breast parenchyma at the nipple base: (4) some timely release of retraction using Bovie's electrocautery dissection at inner surface of the nipple neck. Results: The operation time averaged 15 minutes. The mean follow-up period ranged from 3 to 48 months, with an average of 8.4 months. There were no complications associated with the surgery, such as infection, hematoma, permanent sensory disturbance, or total nipple necrosis except temporary sensory loss in 9 cases, partial nipple necrosis in 7 cases, and recurred inversion in 15 cases. All patients except recurred inversion were satisfied with their results. Conclusion: We believe that our modified purse-string suture is a reliable, simple, safe, and effective method for correcting the inverted nipple.

  • Diffuse alveolar hemorrhage is a rare but serious and frequently life-threatening complication of a variety of conditions. The first goal in the management of patients with diffuse alveolar hemorrhage is to achieve or preserve stability of the respiratory status. Subsequently, the differential diagnosis is aimed at the identification of a remediable cause of the alveolar hemorrhage. The most common causes of diffuse alveolar hemorrhage with glomerulonephritis are microscopic polyangiitis and Wegener's granulomatosis, followed by Goodpasture syndrome and systemic lupus erythematosus. Microscopic polyangiitis (MPA) is a distinct systemic small vessle vasculitis affecting small sized vessels with few or no immune deposits and with no granulomatosus inflammation. The disease may involve multiple organs such as kidney, lung, skin, joint, muscle, gastrointestinal tract, eye, and nervous system. MPA is strongly associated with antineutrophil cytoplasmic autoantibody (ANCA) that is a useful serological diagnostic marker for the most common form of necrotizing vasculitis. Our report concerns a case of microscopic polyangiitis with diffuse alveolar hemorrhage in a 54-year-old man. He was admitted to our hospital due to dyspnea upon exertion and recurrent hemoptysis. Laboratory findings showed hematuria, proteinuria and deterioration of renal function. In the chest CT scan, diffuse ground glass appearance was seen in both lower lungs. A lung biopsy revealed small vessel vasculitis with intraalveolar hemorrhage and showed a positive reaction to against perinuclear ANCA. The patient was treated with prednisolone and cyclophosphamide. Chest infiltration decreased and hemoptysis and hypoxia improved. He is still being followed up in our hospital with a low dose of prednisolone.

  • Objectives : The methods to treat glottic incompetence include thyroplasty type I, arytenoid abduction, and intracordal injection using various materials. The intracordal injection is easy and simple and does not require skin incision. In general, the grafted cartilage shows a high survival rate, a low absorption rate and small voluminous change. The authors performed injection of minced autologous auricular cartilage and fat using a Bruning injector in unilateral vocal cord palsy We evaluate the effect and safety of autologous auricular cartilage intracordal injection. Study Design : Retrospective study. Methods : Auricular cartilage was obtained by incising tragus vertically and it was minced with a scalpel and #15 blade. About 2g of abdominal fat was obtained by small periumbrical incision and cut into small pieces. The minced cartilage was put into a 1$m\ell$ injector and then the injector was filled with fat. The operation was conducted under laryngeal microscope. Minced cartilage was injected into the vocalis muscle at the junction of the middle and posterior third of the vocal fold. In three cases, we performed autologous cartilage intracordal injection. Results : We observed no postoperative complications, such as dyspnea, granulation, inflammation, in any of the cases. The voice was improved compared with the voice prior to operation in all cases. Conclusion : Although the cases are still limited and the observation period is short, we suggest that the autologous cartilage using the auricular cartilage is the ideal and new effective augmentative material in vocal cord palsy.

  • Probiotics improve the immune system. However, the effects of its lactic acid bacteria on atopic dermatitis relief and inflammation improvement is not fully understood. Recently, one of the probiotics, Lactobacillus helveticus HY7801 (HY7801), was found to have an anti-inflammatory effect. In this study, we investigated the effects of HY7801 on atopic dermatitis-induced animal models. After four weeks of oral administration, the group treated with HY7801 showed amelioration of the atopic dermatitis compared to the group receiving placebo. In the HY7801 treated group, the epidermal hyper-proliferation and collagen deposition were inhibited compared to the placebo group, and the secretion amount of the inflammatory factors, such as TNF-α, IL-4 were reduced. In conclusion, these results suggest that HY7801 acts as a functional probiotic via amelioration of the atopic dermatitis such as a decrease of epidermal hyper-proliferation, and collagen deposition and anti-inflammatory effects.

  • Henoch-Sch$\ddot{o}$nlein 자반병 신염과 유사한 증상을 가지는 10세 여자에게 발생한 급격한 신기능 저하를 동반하지 않은 현미경적 다발혈관염 1례를 경험하였기에 보고하는 바이다. 이 혈관염의 경우. 진단 시점 또는 치료 시작할 때의 신장기능 저하가 심할수록 병의 예후가 나쁘므로[20], 사구체 여과율이 떨어지기 전에 빠른 진단과 치료가 필요하다. Henoch-Sch$\ddot{o}$nlein 자반병이 의심될 경우 단백뇨와 혈뇨가 지속되면, 다른 혈관염과의 감별을 위해 ANCA, 신장 조직검사가 도움을 줄 것으로 생각된다.
