Chronic tic disorder or Tourette syndrome is known to be a chronic neuro-behavioral disease for which cognitive behavioral therapy (CBT) strategies have recently been introduced. Here, we report the effectiveness of CBT in a case of childhood chronic tic disorder, which is very common in clinical settings. The DSM-IV clinical diagnosis was applied by a child psychiatrist. The Yale Global Tic Severity Scale, Kovac's children's depression inventory, Spielberger State-Trait Anxiety Inventory, Abbreviated Conners' Rating Scales, and the Dupaul ADHD Rating Scales were used. This case involved a pharmacological treatment-refractory patient over the previous year. Thus, psychiatric consultation was undertaken. Subsequently, we administered five sessions of CBT for four weeks, consisting of symptom evaluation and planning, habit reversal training, and ventilation training. Following four weeks of CBT administration, there were improvements in the scores of the Yale Global Tic Severity Scale and the Clinical Global Improvement scale. Our observations indicate that CBT may be effective in the treatment of childhood tic disorder.

Skull-base osteomyelitis is a rare disease affecting the medulla of the temporal, sphenoid, and occipital bones. In general, it occurs due to external ear canal infections caused by malignant external otitis. Skull-base osteomyelitis usually affects elderly diabetic patients. The patient, a 58-year-old man, was referred for evaluation and management of the left jaw. Clinical examination of the patient revealed pain in the left jaw and mouth-opening deflection to the left. The maximum active mouth opening was measured to about 27 mm. Panoramic, CT, and CBCT revealed bone resorption patterns in the left condyle. Through control of diabetes, continued pharmacological treatment, arthrocentesis, and occlusal stabilization appliance therapy were carried out. The extent of active mouth opening was increased to 45 mm, and pain in the left jaw joint was alleviated. This was a case wherein complications caused by failure to control diabetes induced skull-base osteomyelitis. There is a need for continued discussion about the advantages and disadvantages of arthrocentesis with lavage for patients with skull-base osteomyelitis and other treatment options.

Resveratrol (3,4,5-trihydroxy-trans-stilbene), a phytoalexin found in grape skin, grape products, and peanuts as well as red wine, has been reported to have various biological and pharmacological properties. The purpose of this study was to investigate the anti-obesity effect of resveratrol-amplified grape skin extracts on adipocytes. The anti-obesity effects of grape skin extracts were investigated by measuring proliferation and differentiation in 3T3-L1 cells. The effect of grape skin ethanol extracts on cell proliferation was detected by the MTS assay. The morphological changes and degree of adipogenesis of preadipocyte 3T3-L1 cells were measured by Oil Red-O staining assay. Treatment with extracts of resveratrol-amplified grape skin decreased lipid accumulation and glycerol-3-phosphate dehydrogenase activity without affecting 3T3-L1 cell viability. Grape skin extract treatment resulted in significantly attenuated expression of key adipogenic transcription factors, including peroxisome proliferator-activated receptor, CCAAT/enhancer-binding proteins, and their target genes (FAS, aP2, SCD-1, and LPL). These results indicate that resveratrol-amplified grape skin extracts may be useful for preventing obesity by regulating lipid metabolism.

Tyrosinase (TYR) plays a critical role in cellular melanogenesis and, thus, has been the major target of pharmacological approaches for the control of skin pigmentation. This study examined an alternative molecular approach using TYR-small interfering RNA (siRNA) to control melanogenesis in the human melanocytes. Both the mRNA and protein levels of TYR were significantly lowered by TYR-siRNA treatment, whereas TYR-related protein 1 and TYR-related protein 2 displayed no such changes. TYR-siRNA treatment inhibited the cellular melanin synthesis from the externally supplied TYR substrate L-tyrosine. TYR-siRNA also suppressed melanin synthesis and decreased the viability of cells exposed to ultraviolet radiation, supporting a critical role of melanin in protection against ultraviolet radiation. These results suggest that molecular approaches using siRNA targeted to the enzymes of melanogenic pathway may provide a novel strategy for the control of cell pigmentation.

We previously reported that the exogenous administration of cumambrin A, a sesquiterpene lactone from the dried flowers of Chrysanthemum boreale Makino has a pharmacological effect on normalization of blood pressure in the spontaneously hypertensive rats (SHR). In the present study, we further investigated the effect of cumambrin A on the relaxation of phenylephrine-induced precontracted rat aortic artery rings. The potency of cumambrin A was than compared to verapamil, a well known $Ca^{2+}-channel$ blocker. The results demonstrate that the isolated rat aortic arteries are relaxed to basal tension at a concentration of $5{\times}10^{-5}\;M$ cumambrin A treatment. The results also show that the phenylephrine-induced contraction is inhibited by a pretreatment of cumambrin A. Co-treatment of cumambrin A and verapamil showed a strong synergetic effect on the relaxation of rat aortic artery rings. Thus, these data demonstrate that cumambrin A is a potent relaxant of rat aortic smooth muscle and suggest that cumambrin A modulates intracellular or extracellular $Ca^{2+}$ mobilization.

The effects of sodium taurocholate(STC) and sodium deoxycholate(SDC) on cardiac function were examined by using isolated atria of rabbit and guinea pig and heart of anesthetized frog. Also the antiarrythmic action of STC and SDC on atrial arrhythmias induced by epinephrine or ouabain was studied. The results were following. The cholates exhibited a slight decrease in rate and contractile amplitude of the isolated rabbit atria. The cholates abolished partially the spontaneous arrhythmic occurring in isolated rabbit and guinea pig atria but no effect on the atrial arrhythmia induced by ouabain and epinephrine was observed. Concomitant administration of cholates with ouabain produced a marked prolongation of atrial arrhythmia in comparison to that of ouabain alone in both isolated rabbit and guinea pig atria. The cholates exhibited a marked prolongation in ventricular arrhythmia and cardiac arrest time in comparison to that of ouabain treatment. However, the combined treatment with cholates and ouabain produced a slight prolongation in comparison to that of ouabain alone in the heart of anesthetized frog. The above results suggest that cholates have a slight antiarrythmic effect on the heart but this effectiveness is different from those of propranolol that is non-selective antiarrhythmic drug.

Objectives: To systematically review and evaluate the effectiveness of Chuna manual therapy (CMT) on Pediatric Enuresis. Methods: We searched 12 English, Chinese and Korean databases by using relevant search terms up to October 2017. Every randomized controlled trials (RCTs) of CMT for Pediatric Enuresis were considered for inclusion. The methodological quality of RCTs was assessed by the Cochrane risk of bias tool. Results: Eleven RCTs with 1110 participants were included. The meta-analysis of 11 studies revealed that CMT had statistically significant effects for Pediatric Enuresis compared to other medications in terms of effective rate. Safety issues are minor. Conclusions: This systematic review suggests that CMT may have positive effects on Pediatric Enuresis and safe treatment as a non-pharmacological treatment, but evidence is limited. For a better quality review, more and high-quality RCTs with standardized interventions are needed to offer sufficient evidence on the effects of CMT for Pediatric Enuresis.

General pharmacological studies of LB20304a (a mesylate salt form of a new quinolone antibiotic LB20304 following oral administration of 300 mg/kg and 1000 mg/kg, almost maximum tolerance dose in mice and rat, respectively, were performed in terms of effects on general behaviour, central nervous system, gastrointestinal system, and blood coagulation system in mice and rats. With regards to general behaviour of mice, at oral dose of 300 mg/kg, LB20304a reduced muscle tone and locomotor activity. In terms of CNS, at oral treatment of 300 mg/kg, LB20304a showed some analgesic effects in mice, and oral dose of 1000 mg/kg caused drop in normal body temperature of rat, while it enhanced the pentylenetetrazole-induced clonic convulsion to tonic convulsion and/or death in mice at the doses of unto 300 mg/kg. In addition, LB20304a increased hexobarbital-induced sleeping time two and three times in mice at oral doses of 20 mg/kg and 300 mg/kg, respectively. Rota-rod and traction test in mice were not influenced by the dose of 300 mg/kg and 200 mg/kg, respectively. LB20304a reduced gastric secretion of rat at dose of 1000 mg/kg, and increased intestinal motility of mice at dose of 300 mg/kg. In rats, blood coagulation index, such as PT (prothrombin time) and aPTT (activated partial thromboplastin time) were not affected by the treatment of upto 1000 mg/kg of LB 20304a.

Objectives : Recent studies have suggested that Platycodonis Radix has various pharmacological effects such as anti-cancer, antioxidant, anti-asthma, anti-diabetes, anti-obesity, hepatoprotective, and cardiovascular protection effects. The aim of this study was to investigate the role of water extract of Platycodonis Radix (WPR)-induced autophagy in H460 human lung cancer cells. Methods : H460 cells were treated with WPR and cell viability was calculated by an MTT assay. To evaluate changes in apoptosis- and autophagy-related genes, Western blotting was performed. Two kinds of autophagy inhibitors, 3-Methyladenine (3-MA) and bafilomycin A1, were pretreated to confirm the role of WPR-induced autophagy. Results : WPR reduced the viability of H460 cells in a treatment concentration-dependent manner, which was associated with induction of apoptosis. It was also confirmed that WPR induced autophagy based on the formation of specific intracellular vacuoles and changes in the expression of autophagy-related genes. Interestingly, pretreatment with 3-MA and bafilomycin A1 increased WPR-induced cytotoxicity and apoptosis. Conclusions : WPR induced autophagy at low concentrations and early stages of treatment, but promoted apoptosis at high concentrations and late stages. Moreover, WPR-induced autophagy had a cytoprotective role in H460 cells.
