Objectives This study was carried out to find out the anti-osteoarthritic effects of Mahwangbujaseshin- tang (Mahuangfuzixixintang ) on the monosodium iodoacetate (MIA)-induced osteoarthritis rats. Methods Osteoarthritis was induced by injecting MIA ($50{\mu}l$) into the knee joint of rats. Rats were divided into a 3 groups (n=7). The injection did not fit the normal group. A week later, after the injection of MIA, while control group took normal saline 2 ml, the extract of Mahwangbujaseshin-tang (Mahuangfuzixixintang ) (MBST) (200 mg/kg) was injected to treated group. After that, we examined hind paw weight bearing ability, functions of liver and kidney, serum TNF-$\alpha$, IL-$1{\beta}$, IL-6, $PGE_2$, $LTB_4$, TIMP-1, MMP-9 and hematology. Volume of cartilage was measured by micro CT arthrography. Injury of synovial tissue was measured by H & E, Safranin-O immunofluorescence. Results 1) DPPH and ABTS free radical scavenging activity of MBST was increased according to concentration of MBST and total phenolic contents were in high level. 2) In RAW 264.7 cells, ROS production was significantly decreased in MBST (at 10, $100{\mu}g/ml$) and NO was also decreased but meaningless in MBST (at $100{\mu}g/ml$). 3) In RAW 264.7 cells, IL-6 production was significantly decreased in MBST (at $100{\mu}g/ml$) and TNF-$\alpha$ and IL-$1{\beta}$ production were also decreased but meaningless in MBST (at $100{\mu}g/ml$). 4) In hind legs weight-bearing measurement, level of weight-bearing was increased. 5) Functions of liver and kidney were not affected. 6) TNF-$\alpha$, IL-$1{\beta}$, IL-6, $PGE_2$, $LTB_4$, MMP-9 and TIMP-1 production were significantly decreased. 7) In hematology, the levels of neutrophils, monocytes were significantly decreased and the levels of white blood cells, lymphocytes were also decreased but meaningless. 8) In micro CT-arthrography, cartilage volume was significantly increased. 9) Histopathologically, injury on cartilage and synovial membrane of MBST group was decreased. Conclusions Based on all results mentioned above, Mahwangbujaseshin-tang (Mahuangfuzixixintang) is believed to be meaningful for suppressing the progress of osteoarthritis. And it is related to inhibiting the activity of inflammatory cytokine and injury of volume in cartilage.

Background: Prolonged usage of extracorporeal membrane oxygenation (ECMO) may induce multi-organ failure. This study is aimed to evaluate prognostic factors in the patients with ECMO. Also, the prognosis of ECMO with Kidney Injury Network Scoring system is studied. Materials and Methods: From May 2005 to July 2011, 172 cases of ECMO were performed. The cases of perioperative use of ECMO were excluded. Renal failure patient and younger than 15 years old one were also excluded. As a result, 26 cases were enrolled in this study. Male patients were 15 (57.7%), and mean age was $56.57{\pm}17.03$ years old. Demographic data, ECMO parameters, weaning from ECMO, and application of continuous renal replacement therapy are collected and Acute Kidney Injury Network (AKIN) scores were evaluated just before ECMO and day 1, day 2 during application of ECMO. Results: Venoarterial ECMO was applied in 22 cases (84.6%). The reasons for applications of ECMO were cardiac origin in 21 (80.8%), acute respiratory distress syndrome in 4, and septic shock in 1 case. Successful weaning from ECMO was achieved in 15 cases (57.7%), and survival discharge rate was 9 cases (34.6%). Mean duration of application of ECMO was $111.39{\pm}54.06$ hours. In univariate analysis, myocarditis was independent risk factors on weaning failure. Using the receiver operating characteristic curve, level of hemoglobin on 24 hours after ECMO, and base excess on 48 hours after ECMO were showed more than 0.7. AKIN score was not matched the prognosis of the patients with ECMO. Conclusion: In our study, the prognosis of the patients with myocarditis was poor. Hemoglobin level at first 24 hours, and degree of acidosis at 48 hours were useful methods in relating with prognosis of ECMO. AKIN scoring system was not related with the prognosis of the patients. Further study for prognosis and organ injury during application ECMO may be needed.

After researching on infantile diseases in Hyungsang medicine, the writer got the conclusions as follows. The infants who are excess of the Yang energy need to nourish the Eum- blood. The main causes of the infantile disorders are congenital defect and malfunction of internal organs by nature, as results of these they suffer from mental disorders or being undergrown. And after birth they get ill from internal injury or external affections, mainly epilepsy by retention of undigested food, fever, cough, asthma, nasal obstruction, dermatopathia, and affection by cold, etc. In Hyungsang medicine Dam-body is apt to get ill from deficiency of Eum-blood and bangkwang-body from deficiency of Yang-energy. And infants are hare to be moderate in food, so they become to diseases of the Spleen and stomach, especially infants with Yangmyung type get to epilepsy, cough, skin disorders, and obese for the reasonof overeating. Among main infantile symptoms congenital defects, infantile mental disorders, and convulsive diseases come from congenital defect and malfunciton of internal organs, so it must be treated the symptoms following the reasons. Above all infantile mental disorders are treated not to separate the spirit from the body. And fever, cough and asthma, affection by cold, skin diseases, poor appetite, and obese come from deficiency of Kidney or the deficiency and excess of the Spleen and stomach. In order to prevent from infantile diseases right antenatal training, taking medicine rightly, exercise and eating good habits are needed to give guidance. Seeing through the clinical cases in Hyungsang medicine, we come to know that the infantile mental disorders come out primarily for the reasons of the congenital defect, and the infantile epilepsy come from malfunction of internal organs, and the nasal obstruction and skin diseases come from deficiency of Kidney or the deficiency and excess of the Spleen and stomach.

Objectives The aim of this study was to investigate the effects of Cannabis Fructus on exercise capacity and cognitive function in chronic hypoperfusion induced vascular dementia rat model. Methods Vascular dementia rat models were induced by chronic cerebral hypoperfusion through bilateral common carotid arteries occlusion (BCCAO). All rats were randomly divided into 4 groups: normal group; control group; CF I group (feeding Cannabis Fructus 100 mg/kg); CF II group (feeding Cannabis Fructus 300 mg/kg). In order to study the effects of oral administration of Cannabis Fructus on vascular dementia rat models, corner turn test, hole board test, radial arm maze test, passive avoidance test were taken and Acetylcholine (ACh) activity, Acetylcholinesterase (AChE) activity, serum of Vascular endothelial growth factor (VEGF) protein level were measured. Also histological findings of the liver, kidney, brain and the change of Tau immunoreactive neurons in hippocampus were observed. Results CF I and CF II showed significant improvement in corner turn test, hole board test, radial arm maze test, passive avoidance test, Acetylcholine (ACh) activity, Acetylcholinesterase (AChE) activity, the serum of Vascular endothelial growth factor (VEGF) protein level and the change of Tau immunoreactive neurons in hippocampus. CF I showed more significant effect than CF II in these tests. However in histological observations of the liver and kidney both CF I and CF II showed glomerular injury and hepatotoxicity. Conclusions These results suggest that Cannabis Fructus was helpful in improving exercise capacity and cognitive function on Chronic hypoperfusion induced Vascular Dementia rats. However Cannabis Fructus affects the liver and kidney, therefore suggest that this is an area for further study.

To investigate the potential therapeutic effects of polyphenols in treating Pb induced renal dysfunction and intoxication and to explore the detailed underlying mechanisms. Wistar rats were divided into four groups: control groups (CT), Pb exposure groups (Pb), Pb plus Polyphenols groups (Pb+PP) and Polyphenols groups (PP). Animals were kept for 60 days and sacrificed for tests of urea, serum blood urea nitrogen (BUN) and creatinine. Histological evaluations were then performed. In vitro studies were performed using primary kidney mesangial cells to reveal detailed mechanisms. Cell counting kit-8 (CCK-8) was used to evaluate cell viability. Pb induced cell apoptosis was measured by flow cytometry. Reactive oxygen species (ROS) generation and scavenging were tested by DCFH-DA. Expression level of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-1-${\beta}$ (IL-1-${\beta}$) and IL-6 were assayed by ELISA. Western blot and qPCR were used to measure the expression of ERK1/2, JNK1/2 and p38. Polyphenols have obvious protective effects on Pb induced renal dysfunction and intoxication both in vivo and in vitro. Polyphenols reduced Pb concentration and accumulation in kidney. Polyphenols also protected kidney mesangial cells from Pb induced apoptosis. Polyphenols scavenged Pb induced ROS generation and suppressed ROS-mediated ERK/JNK/p38 pathway. Downstream pro-inflammatory cytokines were inhibited in consistency. Polyphenol is protective in Pb induced renal intoxication and inflammatory responses. The underlying mechanisms lie on the antioxidant activity and ROS scavenging activity of polyphenols.

Objective: To investigate imaging biomarkers of microperfusion in contrast-induced nephropathy (CIN) using contrast-enhanced ultrasound (CEUS). Materials and Methods: The CIN model was fabricated by administering indomethacin (10 mg/kg), L-NAME (15 mg/kg), and iopamidol (10 mL/kg) to Sprague-Dawley rats. After 24 hours, CEUS was performed on CIN (n = 6) and control (n = 6) rats with sulphur hexafluoride microbubbles (SonoVue). From time-intensity curves obtained from the kidney arriving time (AT), acceleration time (AC), time to peak (TTP), and peak enhancement (PE) were measured and compared between the groups. After CEUS, the rats were sacrificed, and cell apoptosis markers were evaluated to confirm the development of CIN. Results: Among CEUS parameters, AT (7.8 ± 1.6 vs. 4.2 ± 0.5 s, p = 0.002), AC (4.7 ± 1.4 vs. 2.0 ± 0.4 s, p = 0.002), and TTP (12.5 ± 2.9 vs. 6.2 ± 0.6 s, p = 0.002) were significantly prolonged in the CIN group compared to controls. PE was significantly higher in the control group than in the CIN group (17.1 ± 1.9 vs. 12.2 ± 2.0 dB, p = 0.004). In kidney tissue, mRNA and protein levels of the apoptotic makers were significantly higher in the CIN group than in the control group (p = 0.003 and p = 0.002). Conclusion: CEUS parameters can be used as imaging biomarkers for microperfusion in CIN. In rats with CIN, AT, AC, and TTP were significantly prolonged, while PE was significantly lower compared to controls.
