Anti-Inflammatory Effects of Bangpungtongsung-San, a Traditional Herbal Prescription

Bangpungtongsung-san (BPTS), a traditional oriental herbal prescription, is widely used for expelling wind, draining heat, and providing general improvement to the immune system. In this study, we investigated the effects of BPTS on induction of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), proinflammatory cytokines, nuclear factor-kappa B (NF-κB), and mitogen-activated protein kinases (MAPKs) in lipopolysaccharide- (LPS- ) stimulated Raw 264.7 cells, and on paw edema in rats. At concentrations of 0.5, 0.75, and 1 mg/mL, treatment with BPTS inhibited levels of expression of LPS-induced NF-κB and MAPKs (ERK, JNK, and p38) as well as production of proinflammatory mediators, such as nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) by LPS. These results suggest that BPTS may exert anti-inflammatory effects via reduction of proinflammatory mediators, including NO, PGE2, TNF-α, and IL-6 through suppression of the signaling pathways of NF-κB and MAPKs in LPS-induced macrophages. In addition, using the carrageenan-induced paw edema assay, an antiedema effect of BPTS was observed in rats. These findings may provide scientific evidence validating the use of BPTS in treatment of patients with heat syndrome in Korean oriental medicine

Two different types of malignant fibrous histiocytomas from pet dogs

We describe 2 cases of malignant fibrous histiocytomas (MFHs) that spontaneously developed in young pet dogs. To classify these tumors, we applied a panel of antibodies (vimentin, desmin, α-SMA, and ED1) and Azan staining for collagen. The MFHs were most consistent with osteoclast-like giant and inflammatory cell types. The first case had positive staining for ED1 and vimentin, and given the osteoclast-like giant cells, calcification sites accompanying peripheral giant cell infiltrates. The latter case, the inflammatory cell type, exhibited a storiform-pleomorphic variant of neoplastic cells, including an ossifying matrix. MFHs are among the most highly aggressive tumors occurring in soft tissue sarcomas in elderly dogs; however, MFHs have been poorly studied from a diagnostic point of view. Herein, we describe the histologic and immunohistologic features of MFHs in detail, thus classifying the subtypes of these tumors

Treadmill Exercise Ameliorates Chemotherapy-Induced Muscle Weakness and Central Fatigue by Enhancing Mitochondrial Function and Inhibiting Apoptosis

Purpose Chemotherapy is associated with the side effects including damage to the mitochondrial DNA. Doxorubicin (DOX) serves as a chemotherapeutic agent for the patients with breast cancer or prostate cancer. DOX causes muscle weakness and fatigue. We investigated the effects of treadmill exercise on DOX-induced apoptosis and mitochondrial dysfunction in relation to central fatigue. For this study, we used the rat model of DOX-induced muscle damage. Methods DOX (2 mg/kg) was intraperitoneally injected 1 time per week for 4 weeks. Treadmill running continued 5 days per week for 4 weeks. Muscle strength and fatigue index in the gastrocnemius were measured. Immunohistochemistry for the expressions of tryptophan hydroxylase (TPH) and 5-hydroxytryptamine (5-HT) in the dorsal raphe was conducted. We used western blot analysis for the expressions of Bax, Bcl-2, and caspases-3 in the gastrocnemius. Mitochondrial function in the gastrocnemius was also evaluated. Results DOX treatment decreased muscle strength with increase of fatigue index in the gastrocnemius. Mitochondria function was deteriorated and apoptosis in the gastrocnemius was enhanced by DOX treatment. Expressions of TPH and 5-HT in the dorsal raphe were increased by DOX treatment. Treadmill exercise attenuated DOX-induced muscle fatigue and impairment of mitochondria function. Apoptosis in the gastrocnemius was inhibited and over-expression of TPH and 5-HT was suppressed by treadmill exercise. Conclusions Apoptosis was enhanced and mitochondria function was deteriorated by DOX treatment, resulting in muscle weakness and central fatigue. Treadmill exercise suppressed apoptosis and prevented deterioration of mitochondria function in muscle, resulting in alleviation of muscle weakness and central fatigue during DOX therapy

Changes of hospitalization trend in the pediatric cardiology division of a single center by increasing adult with congenital heart disease

As a result of advances in pediatric care and diagnostic testing, there is a growing population of adults with congenital heart disease (ACHD). The purpose of this study was to better define the epidemiology and changes in the trend of hospitalizations for ACHD in Korean society. We reviewed outpatient and inpatient data from 2005 to 2017 to identify patient ≥18 years of age admitted for acute care with a congenital heart disease (CHD) diagnosis in the pediatric cardiology division. We tried to analyze changes of hospitalization trend for ACHD. The ratio of outpatients with ACHD increased 286.5%, from 11.1% (1748/15,682) in 2005 to 31.8% (7795/24,532) in 2017. The number of ACHD hospitalizations increased 360.7%, from 8.9% (37/414) in 2005 to 32.1% (226/705) in 2017. The average patient age increased from 24.3 years in 2005 to 27.4 in 2017. The main diagnosis for admission of ACHD is heart failure, arrhythmia and Fontan-related complications. The annual ICU admission percentage was around 5% and mean length of intensive care unit (ICU) stay was 8.4 ± 14.6 days. Mean personal hospital charges by admission of ACHD increased to around two times from 2005 to 2017. (from $2578.1 to$3697.0). Total annual hospital charges by ACHD markedly increased ten times (from $95,389.7 to$831,834.2). The number of hospital cares for ACHD dramatically increased more than five times from 2005 to 2017. We need preparations for efficient healthcare for adults with CHD such as a multi-dimensional approach, effective communication, and professional training

Radiofrequency Ablation of Benign Thyroid Nodules and Recurrent Thyroid Cancers: Consensus Statement and Recommendations

Thermal ablation using radiofrequency is a new, minimally invasive modality employed as an alternative to surgery in patients with benign thyroid nodules and recurrent thyroid cancers. The Task Force Committee of the Korean Society of Thyroid Radiology has developed recommendations for the optimal use of radiofrequency ablation for thyroid nodules. These recommendations are based on a comprehensive analysis of the current literature, the results of multicenter studies, and expert consensus
