  • Objectives : To investigate the active compounds and therapeutic mechanisms of Atractylodes Lancea(Thunb.) D.C. and Magnolia Officinalis Rehder et Wilson in the treatment of dermatitis accompanied by pruritus, as well as their potential to complement or replace standard drugs. Methods : We conducted the network pharmacological analysis. We selected effective ingredients among the active compounds of research target herbs. Then we explore pathway/terms of the common target proteins among research target herbs, fexofenadine and disease. Results : We selected 9 active compounds are selected from Atractylodes lancea and identified 231 target proteins. Among them, 74 proteins are associated with inflammatory skin diseases that cause pruritus. These proteins are involved in various pathways including, 'Nitric-oxide synthase regulator activity', 'Hydroperoxy icosatetraenoate dehydratase activity, Aromatase activity', 'RNA-directed DNA polymerase activity', 'Arachidonic acid metabolism', 'Peptide hormone processing', 'Chemokine binding' and 'Sterol biosynthetic process'. Additionally, coregenes are involved in 'IL-17 signaling pathway'. Similarly, we selected 2 active compounds from Magnolia officinalis and identified 133 target proteins. Among them, 33 proteins are related to inflammatory skin diseases that cause pruritus. These proteins are primarily involved in 'Vascular associated smooth muscle cell proliferation' and 'Arachidonic acid metabolism'. There is no significant difference between the pathways in which coregenes are involved. Conclusions : It is expected that Atractylodes Lancea will be able to show direct or indirect anti-pruritus and anti-inflammatory effects on skin inflammation accompanied pruritus through suppressing inflammation and protecting skin barrier. Meanwhile, it is expected that Magnolia Officinalis will only be able to show indirect anti-inflammation effects. Therefore, Atractylodes Lancea and fexofenadine are believed to complement each other, whereas Magnolia Officialinalis is expected to provide supplementary support on skin disease.

  • Background: Inflammation plays a major role in the development and progression of gastric and other gastrointestinal tumors. The IL-17 family of cytokines has been under investigation as targets of immunotherapy. Materials and Methods: We investigated the levels of IL-17A inflammatory cytokine in the sera of 57 patients with gastric cancer (GC) and 90 healthy age/sex matched controls using ELISA methods. Results: In only 5 (8.8%) of the patients' sera was IL-17A detectable. No IL-17A was apparent in the sera of healthy controls. The maximum concentration of IL-17A in patients was 7.004 pg/ml. Vascular and lymphatic invasions were only seen in one of the 5 positive cases. Although all of them were in the age group >60 years, no correlation was seen between age and IL-17A level. These results are somewhat different from our findings for colorectal cancer (CRC) in the same population. Conclusions: It is possible that the inflammopathology of CRC and GC are rather different, at least in Fars, a southern province of Iran.

  • Rheumatoid arthritis is a long lasting autoimmune disorder that primarily affects joints, and patients with rheumatoid arthritis are predisposed to development of chronic skin ulcers. In addition, skin ulcers with rheumatoid arthritis tend to persist despite treatment because of sustained inflammation and poor healing capacity. Treatment of skin ulcers involves medications, wound coating agents, and surgical procedures including skin grafting, however, wound dressing or skin grafts are generally excluded because of excessive cost and time and poor intake rate. The dorsal metacarpal artery perforator (DMAP) flap, a vascular island flap for coverage of soft tissue defects on the fingers, provides promising results including matched quality and color. We experienced a case of DMAP flap for reconstruction of a rheumatoid ulcer, and a DMAP flap may be considered as a good faithful option for treatment of patients with rheumatoid ulcer.

  • 인체에서 발생하는 체열을 과학적으로 이용하여 질병을 진단하고 치료과정을 관찰하고 예후를 추측할 수 있는 Thermography는 현대의학의 임상 여러분야에서 응용할 수 있는 유용한 진단장비에 속한다 하겠다. 인체의 피부온도는 좌우 대칭적으로 온도분포를 나타내며 여러가지 생리학적인 원인에 의하여 온도는 변화할 수 있으며, 그러한 온도변화는 여러 질병과의 연관성을 갖게 된다. Thermography는 유방암세포의 증식에 따른 유방체표면의 초기온도 상승을 screening 함으로서 조기에 유방암을 발견할 수 있으며, 척추의 신경근 자극에 따른 체열분포를 파악함으로서 신경근의 이상유무 및 척추질환을 진단할 수 있으며, 말초 혈액순환 장애 등으로 인한 질환에 있어서도 뚜렷한 체표면 온도분포를 나타내 줌으로서 혈액순환의 장애분포를 시각적으로 관찰할 수 있는 이점을 지니고 있다. 또한 정형 물리치료 분야에 속하는 근-골격계 질환에 있어서의 근육통, 압통점, 염좌, 염증질환 등을 구별할 수 있고 나아가 치료 전후에 적외선 체열검사를 실시해 봄으로서 치료전이나 치료결과에 대한 객관적인 평가를 할 수 있다는데 큰 의의가 있다고 하겠다.

  • Free tissue transplantation is commonly performed with the brilliant achievement in microsurgery and anticoagulants and antithrombotic agents have been prescribed in the procedures. However, there is no clean-cut indication as to which agents would be more effective in every steps and final consequences. Low molecular weight heparins inhibiting coagulation in plateletrich plasma and acting on the vascular endothelium have antithrombotic and fibrinolysis action. The experiment with rat groin free flap transplantation after 6-hour ischemia and injection of the low molecular weight heparin was performed and the results between the injection and non-injection group were analysed as follows, 1. Both of the 24-hour groups, vessel patency was not proportional to color change of the groin flap. 2. On the second day after anastomois, heparin-injection group showed intact intima, patent lumen without thrombus, and mild granulomatous inflammation around the suture material and control group with doubtful patency revealed intimal loss and thrombus formation. 3. On the 5th, 7th, and 9th postoperative day, heparin group was patent in anastomosis and showed acute inflammatory cells. 4. The 7th-week period, heparin-injection group showed intact flap color, patent lumen with intact intima and persistent foreign body granuloma.

  • Microscopic polyangiitis (MPA) is a necrotizing vasculitis involving the small vessels without granulomatous inflammation. Most MPA initially presents with renal involvement without pulmonary involvement. Isolated and initially presenting alveolar hemorrhage is very rare. The patient was a 39-year-old female with a progressive cough, dyspnea, and blood-tinged sputum for the previous 5 days. We determined that her condition was MPA though VATS lung biopsy and renal biopsy. After 2 months of steroid therapy, the chest lesions had improved. We report here a rare case of MPA with isolated and initial involvement of the lung with a review of the literature.

  • Lysozyme protects us from the ever-present danger of bacterial infection and binds to bacterial lipopolysaccharide (LPS) with high affinity. Beyond its role in the activation of protein C, the endothelial cell protein C receptor (EPCR) plays an important role in the cytoprotective pathway. EPCR can be shed from the cell surface, which is mediated by tumor necrosis factor-α converting enzyme (TACE). However, little is known about the effects of lysozyme on EPCR shedding. We investigated this issue by monitoring the effects of lysozyme on phorbol-12-myristate 13-acetate (PMA)-, tumor necrosis factor (TNF)-α-, interleukin (IL)-1βand cecal ligation and puncture (CLP)-mediated EPCR shedding and underlying mechanism. Data demonstrate that lysozyme induced potent inhibition of PMA-, TNF-α-, IL-1β-, and CLP-induced EPCR shedding. Lysozyme also inhibited the expression and activity of PMA-induced TACE in endothelial cells. These results demonstrate the potential of lysozyme as an anti-EPCR shedding reagent against PMA-mediated and CLP-mediated EPCR shedding.

  • To achieve better understanding of the effects of monosodium-L-glutamate(MSG) against $CCl_4$ fatty liver in Wister male rats, 5% MSG solution was given as drinking water and $CCl_4$ 0.1 ml/kg was injected subcutaneously twice a week for four weeks. It was showed that increased hepatic phospholipid and hepatic triacylglycerol levels by $CCl_4$ challenge were significantly decreased by additionnal MSG, respectively. However, MSG had no apparent effect on the elevated hepatic cholesterol level in the presence of $CCl_4$. Histologically, additional MSG markedly inhibited fatty degeneration, spotty necrosis, inflammation and periportal vascular proliferation manifested by $CCl_4$. respectively. These results indicated that effects of MSG against $CCl_4$ induced-fatty liver appeared to be involved with partial restoration of altered hepatic lipid composition.

  • This study examined the mechanisms underlying the effects of the vasorelaxation active substance(VAS), dimethyladenosine-5'-L-arabinose, and its partial purification fraction on nitric oxide synthase in improving erectile dysfunction with particular focus on the nitric oxide (NO)-cGMP pathways. Two rat models, 9-month-old SD rats and 11-month-old SD rats, were given VAS(40 mg/kg per day) for 4 days, The aqueous fraction of silworm male pupae extract; semi-purified VAS(100 mg/kg per day) for 10 days, respectively. The NOS activities of the following three enzymes were examined: neuronal NO synthase(nNOS), inducible NOS(iNOS), endothelial NOS(eNOS), vascular endothelial growth factor on endothelial cells(VEGF) and anti-inflammation effect of Tumor necrosis factor-$\alpha$. The results showed increases in the nitric oxide synthase activities. Western blotting of the tissue homogenate showed an increase in the nNOS level in the brain and tongue, and an increase in the endothelial NO synthase(eNOS) level in penis. However, there was little association with VEGF production in HUVEC endothelial cells and no relationship with TNF-$\alpha$ which showed low levels.

  • Cervical cancer is a leading cause of morbidity and mortality in women worldwide. Although the human papillomavirus (HPV) is considered the major causative agent of cervical cancer, yet the viral infection alone is not sufficient for cancer progression. The etiopathogenesis of cervical cancer is indeed complex; a precise understanding of the complex cellular/molecular mechanisms underlying the initiation, progression and/or prevention of the uterine cervix is therefore essential. Autophagy is emerging as an important biological mechanism in targeting human cancers, including cervical cancer. Furthermore, autophagy, a process of cytoplasm and cellular organelle degradation in lysosomes, has been implicated in homeostasis. Autophagic flux may vary depending on the cell/tissue type, thereby altering cell fate under stress conditions leading to cell survival and/or cell death. Autophagy may in turn govern tumor metastasis and subsequent carcinogenesis. Inflammation is a known hallmark of cancer. Vascular insufficiency in tumors, including cervical tissue, leads to depletion of glucose and/or oxygen perturbing the osmotic mileu causing extracellular acidosis in the tumor microenvironment that may eventually result in autophagy. Thus, targeted manipulation of complex autophagic signaling may prove to be an innovative strategy in identification of clinically relevant biomarkers in cervical cancer in the near future.
