In Vivo and In vitro antispasmodic effects of Jun-Si-Baek-Chul-San, a Traditional Korean Polyherbal Medicineconsisted of 7 types of herbs were observed in the present study. To clarify the effects of Jun-Si-Baek-Chul-San, on accelerating small intestinal movement induced by the stimulation of cholinergic neurotransmission, we evaluated the effects of Jun-Si-Baek-Chul-San on In vivo carbachol (an acetylcholinergic agent)-accelerated mice small intestinal transit and on In vitro contractions induced by low-frequency electrostimulation, KCl, histamine or acetylcholine using isolated guinea pig ileum. To induce the acceleration of mice small intestinal transit, Carbachol 1 mg/kg was once subcutaneously dosed 15min before last administration of the test drugs. In the present study, Jun-Si-Baek-Chul-San 500, 250 and 125 mg/kg or domperidone 20 mg/kg were orally pretreated on the carbachol-accelerated mice small intestinal transit once a day for 7 days and the small intestinal transit rateof activated charcoal powder were monitored. In vitro assays, Jun-Si-Baek-Chul-San1, 0.1, 0.01 and 0.001 mg/ml or domperidone $2{\times}10^{-5}M$ were treated 10min before ileal contraction was induced by filed stimulation, acetylcholine, KCl and histamine, and the % changes of contractions were observed compared to the treatment of inducer alone. In spontaneous contraction, the % changes of contractions were observed compared to treatment of vehicle alone at 10min after Jun-Si-Baek-Chul-San or domperidone treatment. The efficacy of Jun-Si-Baek-Chul-San was compared to those of domperidone. High concentration, 1 mg/ml of Jun-Si-Baek-Chul-San was found to decrease the spontaneous contraction of the isolated guinea-pig ileum. In addition, Jun-Si-Baek-Chul-San decrease contractions induced by electrostimulation, acetylcholine, histamine and KCl in the isolated guinea-pig ileum. In addition, Jun-Si-Baek-Chul-San effectively inhibited the accelerated small intestinal movement induced by carbachol stimulation of cholinergic neurotransmission in In vivo. Based on the results, although the exact molecular or action mechanism and which herbs or compound in Jun-Si-Baek-Chul-San are responsible for actions, it was concluded that Jun-Si-Baek-Chul-San normalization in the accelerated intestinal motility might be interfere with a variety of muscarinic, adrenergic and histaminic receptor activities or with the mobilization of calcium ions required for smooth muscle contraction non-specificly. Therefore, it is expected that Jun-Si-Baek-Chul-San will be promising as a prescription of clinical treatment of digestive tract disorders such as accelerated the motility of intestine, diarrhea or intestinal painful contractions.

<P>Tetanus toxin (TeT) is an exotoxin and has a capacity for neuronal binding and internalization. In the present study, we compared changes in the immunoreactivities and protein levels of interleukin (IL-) 2 as a pro-inflammatory cytokine and IL-4 as an anti-inflammatory cytokine in the hippocampus proper (HP) and dentate gyrus (DG) after systemic treatment of 10 or 100?ng/kg TeT into mice. In this study, we could not find any neuronal damage or loss in any subregions of the hippocampus after TeT treatment. In the control groups, strong IL-2 immunoreactivity was shown in the stratum pyramidal (SP) of the HP and in the granule cell layer (GCL) of the DG. At 6?h post-treatment, IL-2 immunoreactivity was hardly detected in the SP and GCL; however, strong IL-2 immunoreactivity was shown in the stratum oriens of the HP in both the groups. Thereafter, intermediate IL-2 immunoreactivity was shown in the SP and GCL. On the other hand, intermediate IL-4 immunoreactivity was detected in the SP and GCL of the control groups. At 6?h post-treatment, IL-4 immunoreactivity in the SP and GCL was apparently increased. Thereafter, IL-4 immunoreactivity was lower than that at 6?h post-treatment. In brief, IL-2 and 4 immunoreactivities were easily detected in SP and GCL in the controls and dramatically decreased and increased at 6?h post-treatment, respectively.</P>

<P>Chung-pae (CP) inhalation therapy is a method frequently used in Korea to treat lung disease, especially chronic obstructive pulmonary disease (COPD). This study investigated the effects of CP inhalation on a COPD animal model. C57BL/6 mice received porcine pancreatic elastase (PPE) and lipopolysaccharide (LPS) alternately three times for 3 weeks to induce COPD. Then, CP (5 or 20 mg/kg) was administered every 2 h after the final LPS administration. The effect of CP was evaluated by bronchoalveolar lavage (BAL) fluid analysis, histological analysis of lung tissue, and reverse transcription polymerase chain reaction analysis of mRNA of interleukin- (IL-) 1<I>β</I>, tumor necrosis factor- (TNF-) <I>α</I>, IL-6, and tumor growth factor- (TGF-) <I>β</I>. Intratracheal CP administration reduced the number of leukocytes and neutrophils in BAL fluid, inhibited the histological appearance of lung damage, and decreased the mRNA levels of the proinflammatory cytokines IL-1<I>β</I>, TNF-<I>α</I>, IL-6, and TGF-<I>β</I>. Intratracheal CP administration effectively decreased the chronic inflammation and pathological changes in a PPE- and LPS-induced COPD mouse model. Therefore, we suggest that CP is a promising strategy for COPD.</P>

Objectives : Taraxacum coreanum (TC) have been used as a traditional medicine to treat inflammatory diseases and anti-oxidant effect in Korea. However, the anti-inflammatory effect of TC water extract on lipopolysaccharide (LPS)-induced inflammation is not well-known. Therefore, this study was performed to identify the anti-inflammatory effect of TC on LPS induced inflammatory. Methods : RAW 264.7 cells were treated with 500 ng/mL of LPS. Water extracts of TC (0.1, 0.25, 0.5 mg/ml) was treated 1 h prior to LPS. Cell viability was measured by MTT assay. Levels of nitric oxide (NO) were measured with Griess reagent and pro-inflammatory cytokines were measured by enzyme-linked immunosorbent assay (ELISA) and real-time polymerase chain reaction (real-time PCR). We also examined molecular mechanisms such as mitogen-activated protein kinases (MAPKs) and nuclear factor-B (NF-κB) activation by western blot. Results : Water Extract from TC itself did not have any cytotoxic effect in RAW 264.7 cells. TC treatment inhibited the production of NO production, and pro-inflamamtory cytokines such as interleukin (IL)-6 and IL-1β on protein and mRNA levels. In addition, TC treatment inhibited the LPS-induced activation of MAPKs such as extracellular signal-regulated kinase1/2 (ERK1/2), p38 kinases (p38), c-Jun NH2-terminal kinase (JNK) and NF-κB. Conclusions : In summary, our result suggest that treatment of TC could reduce the LPS-induced inflammation. Thereby, TC could be used as a protective agent against inflammation. Also, this study could give a clinical basis that TC could be a drug or agent to prevent inflammation.

A novel synthetic process for polyimide(PI)/polymethylsilsesquioxane(PMSSQ) hybrid films has been studied by using supercritical CO_2 media. At the first, PI precursors were synthesized by a reaction of dianhydrides and diisocyanates instead of the reaction of dianhydrides and diamines. Coupling agents, aminopropylethoxysilanes(APMS) modified the end groups of PI precursors for the hybrid reaction of PI precursors for the hybrid reaction of PI precursor and methyltriethoxysilans(MTES). Inorganic monomer, MTES could also react with another MTES via sol-gel process and became PMSSQ which consisted of a network structure. Hybrid solution was spum on a silicone wafer substrate. The PI precursor parts in the hybrid films were imidized by varying the temperature and the pressure of supercritical CO_2.We confirmed the bybridization through the FT-IR. There were intrenal multi-pores which could be classified by two deferent size, micrometer size and nanometer size in the cross-setional morphology of PI/PMSSQ hybrid films. Micro-pores were developed by removal of by-product, CO_2 during the supercritical imidization reaction and nano-pores were generated by sol-gel reaction and supercritical extraction.

Objectives : Cinnamomi Ramulus (CR), the young twing of Cinnamomi loureirii nees, has been used for treating symptoms related to pain. rheumatic arthritis and inflammation in Korean herb medicine. This study was carried out to investigate the anti-inflammatory effect of CR in vivo and in vitro. Methods : Extracts of CR were prepared and the chemical components of the extracts were examined by gas chromatography-mass spectrometry (GC-MS). The extracts were administrated to the rat paw edema model induced by carrageenan to evaluate the anti-inflammatory effect of CR. The expressions of nitric oxide (NO). prostaglandin E2(PGE2), inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 were also quantified in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages to survey the effect of CR in vitro. The main components were cinnamaldechyde and coumarin. Results : We examined the anti-inflammatory activity of the 80% ethanol extract of Cinnamomi Ramulus in vivo by using carrageenan-induced rat paw edema model. Maximum inhibition of 54.9% was noted at the dose of 1000㎎/㎏ after 2 hours of drug administration in carrageenan-induced rat paw edema and this showed a potent anti-inflammatory effect. Conclusions : The results showed that Cinnamomi Ramulus suppressed dose-dependently LPS-induced NO production in RAW 264.7 macrophages and also decreased iNOS protein expression. Cinnamomi Ramulus also showed a significant inhibitory effect in LPS-induced PGE2 production and COX-2 expression.

( Ho Young Lee ),( Hye Kyung Ha ),( Jun Kyoung Lee ),( Sang Joon Park ),( Seung Il Jeong ),( Hyeun Kyoo Shin ) 한국응용약물학회 2014 Biomolecules & Therapeutics(구 응용약물학회지) Vol.22 No.5

Broussonetia kazinoki Siebold. (B. kazinoki) has long been used in the manufacture of paper in Asian countries. Although B. kazinoki leaves (BK) have been employed in dermatological therapy, use of BK has not been tested in patients with atopic dermatitis (AD). Using Nc/Nga mice, which are genetically predisposed to develop AD-like skin lesions, we confirmed the efficacy of BK in AD treatment. BK extract was applied topically to Dermatophagoides farinae-induced AD-like lesions in Nc/Nga mice, and the effects were assessed both clinically and by measuring skin thickness on the back and ears. We measured the effects of BK extract on plasma levels of IgE and IL-4. We also measured the ability of BK extract to inhibit the secretion of hTARC in HaCaT cells after stimulation by TNF-α and IFN-γ. We found that BK extract significantly reduced ear and dorsal skin thickness and the clinical signs of AD, as well as significantly down-regulating the plasma levels of IgE and IL-4 (p<0.01 for each comparison). Moreover, 500 μg/ mL of BK extract inhibited hTARC secretion in HaCaT cells by activated TNF-α/IFN-γ by about 87%. These findings suggest that topical application of BK extract has excellent potential in the treatment of AD.

Brugada syndrome is characterized by right bundle branch block morphology and ST segment elevation in the right precordial leads and a propensity to develop ventricular arrhythmias. Mutations in a cardiac sodium channel gene have been linked to this syndrome, and the ionic mechanisms responsible for the electrocardiographic phenotype are temperature-dependent. This case report describes a patient in whom a typical Brugada ECG pattern developed during fever and returned normal ECG after fever was subsided.
