Abstract
BACKGROUND AND OBJECTIVE Global Lung Function Initiative (GLI) 2012 equations were developed to resolve the age-related disparity in interpreting spirometry results. Local validation of the equation is needed, especially in Northeast Asian children. This study evaluated the GLI equation in Korean children. METHODS Spirometry indices (FEV1, FVC, FEV1/FVC, and FEF25%-75%) and clinical information were gathered from three population-based birth cohorts. Predicted GLI reference values and z scores of spirometry results were calculated for 1239 healthy children. The mean, standard deviation of z scores were compared with the expected 0 and 1. Probabilities of falling below the lower limit of normal (LLN) (z score: -1.64) were compared with the expected value 5%. GLI z scores were assessed according to low (<-2), normal (≥-2 and ≤2), and high (>2) BMI z score groups. RESULTS Mean z scores significantly differed from 0 for FEV1/FVC in males (mean [95% confidence interval]: 0.18 [0.08, 0.27]) and forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) in females (-0.23 [-0.31, -0.15] and -0.26 [-0.36, -0.16], respectively). The standard deviation was larger than 1 for all variables in males and FVC and FEV1/FVC in females. The probability of falling below the LLN was significantly larger than 5% for FEV1 (12.13% [9.64, 14.77]), FVC (15.86% [13.06, 18.81]), and forced expiratory flow at 25%-75% of forced vital capacity (FEF25%-75%) (7.31% [5.29, 9.49]) in males and FVC (11.91% [9.40, 14.60]) in females. FEV1 and FVC z scores increased across low to high body mass index (BMI) groups, and FEV1/FVC decreased from low to high BMI groups. CONCLUSION GLI equations marginally differ from real-world values, which should be considered by pulmonologists in practice or research.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Platycodon grandiflorus (Jacq.) A.DC. is a well-known traditional herbal medicine administered for bronchitis and inflammatory diseases. Especially, anti-inflammatory effect of fermented P. grandiflorus (Jacq.) A.DC. extract (FPGE) was higher than that of P. grandiflorus (Jacq.) A.DC. extract. However, toxicological information for FPGE is lacking. AIM OF THE STUDY In this study, we establish a toxicological profile for FPGE by testing genotoxicity, acute and 13-week subchronic toxicity. MATERIALS AND METHODS FPGE was evaluated with bacterial reverse mutation, chromosome aberration, and micronucleus test. For the acute- and 13-week subchronic toxicity tests, FPGE was administered orally at doses of 0, 750, 1500, and 3000 mg/kg in SD rats. RESULTS The results of the genotoxic assays indicated that FPGE induced neither mutagenicity nor clastogenicity. The acute toxicity test showed that FPGE did not affect animal mortality, clinical signs, body weight changes, or microscopic findings at ≤ 3000 mg/kg. The approximate lethal dose (ALD) of FPGE in SD rats was >3000 mg/kg. For the 13-week subchronic toxicity assay, no FPGE dose induced any significant change in mortality, clinical signs, body or organ weight, food consumption, ophthalmology, urinalysis, hematology, serum chemistry, gross findings and histopathologic examination in either SD rat sex. The rat no observed adverse effects level (NOAEL) for FPGE was set to 3000 mg/kg. CONCLUSIONS The present study empirically demonstrated that FPGE has a safe preclinical profile and indicated that it could be safely integrated into health products for atopic dermatitis treatment.

Abstract
Separating the immunosuppressive activity of FK506 (1) from its neurotrophic activity is required to develop FK506 analogues as drugs for the treatment of neuronal diseases. Two new FK506 analogues, 9-deoxo-36,37-dihydro-prolylFK506 (2) and 9-deoxo-31-O-demethyl-36,37-dihydro-prolylFK506 (3) containing a proline moiety instead of the pipecolate ring at C-1 and modifications at the C-9/C-31 and C-36-C-37 positions, respectively, were biosynthesized, and their biological activities were evaluated. The proline substitution in 9-deoxo-36,37-dihydroFK506 and 9-deoxo-31-O-demethyl-36,37-dihydroFK506 reduced immunosuppressive activity by more than 120-fold, as previously observed. Compared with FK506 (1), 2 and 3 exhibited ∼1.2 × 105- and 2.2 × 105-fold reductions in immunosuppressive activity, respectively, whereas they retained almost identical neurite outgrowth activity. Furthermore, these compounds significantly increased the strength of synaptic transmission, confirming that replacement of the pipecolate ring with a proline is critical to reduce the strong immunosuppressive activity of FK506 (1) while enhancing its neurotrophic activity.

Abstract
FK506, also known as tacrolimus, is a clinically important immunosuppressant drug and has promising therapeutic potentials owing to its antifungal, neuroprotective, and neuroregenerative activities. To generate various FK506 derivatives, the structure of FK506 has been modified by chemical methods or biosynthetic pathway engineering. Herein, we describe the mode of the antifungal action of FK506 and the structure-activity relationship of FK506 derivatives in the context of immunosuppressive and antifungal activities. In addition, we discuss the neurotrophic mechanism of FK506 known to date, along with the neurotrophic FK506 derivatives with significantly reduced immunosuppressive activity. This review suggests the possibility to generate novel FK506 derivatives as antifungal as well as neuroregenerative/neuroprotective agents.

Abstract
Purpose Data are lacking on the association between the allergic rhinitis (AR) phenotype and sensitization to specific allergens or bronchial hyperresponsiveness (BHR) in children. We here investigated risk factors and comorbidities, including sensitization to specific allergens and BHR, for the AR phenotype by AR and its Impact on Asthma (ARIA) classification in a general population-based birth cohort study. Methods We enrolled 606 children aged 7 years from the Panel Study of Korean Children. The AR phenotype was assigned in accordance with the ARIA classification in children. Skin prick tests and Provocholine provocation test were performed. Risk factors and comorbidities for AR phenotypes were then analyzed. Results The prevalence of mild and moderate to severe AR in our study cohort was 37.2% and 8.8%, respectively. Recent use of analgesics or antipyretics and current cat ownership were associated with the risk of mild persistent AR. Sensitizations to Dermatophagoides Pteronyssinus (Der p), Japanese hop and cat were associated with moderate to severe persistent AR. Children with moderate to severe AR had a higher risk of current asthma and BHR compared to mild AR cases (adjusted odds ratio [aOR], 5.26; 95% confidence interval [CI], 1.77–15.62). Moderate to severe AR with allergic sensitization was associated with the highest risk of BHR (aOR, 11.77; 95% CI, 3.40–40.74). Conclusions Moderate to severe-persistent AR is more closely related to respiratory comorbidities and sensitizations than mild AR. Stratifying the AR phenotype by ARIA classification may assist in disease management.

Abstract
A reduction in the strong immunosuppressive activity of FK506 (1) is essential for developing this compound as an antifungal agent. Seven new FK506 analogues modified at both the FK506-binding protein 12- and the calcineurin-binding regions were biosynthesized. 9-DeoxoFK520 (7) exhibited a >900-fold reduction in the in vitro immunosuppressive activity but maintained significant antifungal activity, indicating that the C-9 and C-21 positions are critical for separation of immunosuppressive and antifungal activities. 7 exhibited robust synergistic antifungal activity with fluconazole. FK506 (1) is a 23-membered macrolide produced by several Streptomyces species and is used as an immunosuppressive drug to prevent the rejection of transplanted organs. FK506 has also exhibited antifungal, neuroprotective, and neuroregenerative activities. In humans, FK506 binds to FK506-binding protein (FKBP) 12, and the resulting FKBP12-FK506 complex interacts with a Ca2+-calmodulin-dependent phosphatase, calcineurin (CaN). Inactivation of CaN by forming the FKBP12-FK506-CaN ternary complex prevents the activation of nuclear factor of activated T cells (NF-AT), inhibiting the production of interleukin-2 and subsequent T-cell proliferation. This CaN signaling pathway also plays a critical role in the growth and pathogenesis of major fungal pathogens such as Cryptococcus neoformans, Candida albicans, and Aspergillus fumigatus. Therefore, the synthesis of FK506 analogues that can discriminate human FKBP12/CaN from its fungal counterparts may separate antifungal activity from the immunosuppressive activity, thereby allowing the development of a novel antifungal agent.

Abstract
BACKGROUND Sensitization is associated with the exacerbation, severity, and prognosis of allergic diseases in children OBJECTIVE: We characterized the association between sensitization patterns and allergic diseases. METHODS A cohort of 548 children was enrolled from Panel Study of Korean Children (PSKC) study. Skin prick tests (SPTs) for 18 common allergens, blood tests, and methacholine bronchial challenge tests were performed at age 7. The Korean version of International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was used. RESULTS The sensitization rate on SPTs was 46.4%. Sensitization to indoor allergens showed an association with symptoms of asthma (adjusted odds ratio [aOR], 2.39; 95% confidence intervals [95% CIs], 1.10-5.23), allergic rhinitis (AR, aOR 2.08, 95% CIs 1.42-3.06), and atopic dermatitis (AD, aOR 2.36, 95% CIs 1.24-4.50) in the preceding 12 months. In contrast, sensitization to outdoor allergens was associated with AR diagnosis only (aOR 2.40, 95% CIs 1.30-4.41). The number of sensitized allergens was associated with a lifetime diagnosis and symptoms in the preceding 12 months of AR and asthma, but not with AD or BHR. A higher degree of sensitization to indoor allergens was associated with symptoms in the preceding 12 months of asthma, AR, AD, and that for outdoor allergens was associated with symptoms in the prior 12 months of asthma and AR. CONCLUSION The sensitization patterns including allergen type, number, and degree of sensitization are helpful for interpreting the association between sensitization and allergic diseases and identifying the pathophysiologies and diverse phenotypes of allergic diseases.

Abstract
BACKGROUND Although bronchial responsiveness (BR) is usually categorized as normal or hyperresponsive to aid the diagnosis of asthma, it exists on a continuous spectrum, not in a dichotomous manner. We aimed to evaluate the distribution profile of BR in a general population of 7-year-olds. METHODS In 2015, 7-year-old Korean children from a nationwide birth cohort study visited regional study hospitals for skin prick test, standard spirometry, and bronchial provocation to establish reference values for the general population. Their BR degrees were categorized into five ordered groups: hyperresponsive BRs were classified into group 1 (provocative concentration (PC) of methacholine causing a 20% fall in forced expiratory volume in 1 second [FEV1], PC20 of <4 mg/mL) and group 2 (PC20 of ≥4 mg/mL and <16 mg/mL), and nonresponsive BRs were categorized into group 3 (final FEV1 percentage fall after inhaling 16 mg/mL of methacholine [FEV1%fall] of >15% and ≤20%), group 4 (FEV1%fall of >10% and ≤15%), and group 5 (FEV1%fall of ≤10%). RESULTS In total, 559 subjects finished all tests reliably. Groups 1 and 2 comprised 10.0% and 15.7% of the total population, respectively. Groups 3, 4, and 5 comprised 14.7%, 18.4%, and 41.1%, respectively. As the group number increased, the proportion of those with recent wheezing and those with indoor allergen sensitization decreased (P for trend = 0.001 and P for trend < 0.001, respectively), and the baseline FEV1/FVC increased (P for trend < 0.001) CONCLUSION: BR of the 7-year-olds in the general population, while showing a wide distribution across phenotypes, is associated with allergic symptoms, negatively correlated with baseline lung function and positively correlated with indoor allergen sensitization.

Abstract
BACKGROUND Bronchiectasis is a chronic pulmonary disease characterized by progressive and irreversible bronchial dilatation. The aim of the present study was to investigate the etiologies and clinical features of bronchiectasis in Korean children. METHODS We performed a retrospective review of the medical records for children diagnosed with bronchiectasis between 2000 and 2017 at 28 secondary or tertiary hospitals in South Korea. RESULTS A total of 387 cases were enrolled. The mean age at diagnosis was 9.2 ± 5.1 years and 53.5% of the patients were boys. The most common underlying cause of bronchiectasis was preexisting respiratory infection (55.3%), post-infectious bronchiolitis obliterans (14.3%), pulmonary tuberculosis (12.3%), and heart diseases (5.6%). Common initial presenting symptoms included chronic cough (68.0%), recurrent pneumonia (36.4%), fever (31.1%), and dyspnea (19.7%). The most predominantly involved lesions were left lower lobe (53.9%), right lower lobe (47.1%) and right middle lobe (40.2%). No significant difference was observed in the distribution of these involved lesions by etiology. The forced expiratory volume in 1 s (FEV1) levels were lowest in cases with interstitial lung disease-associated bronchiectasis, followed by those with recurrent aspiration and primary immunodeficiency. CONCLUSIONS Bronchiectasis should be strongly considered in children with chronic cough and recurrent pneumonia. Long-term follow-up studies on pediatric bronchiectasis are needed to further clarify the prognosis and reduce the disease burden in these patients.

Abstract
Purpose Adherence is a major component of successful medical treatment. However, non-adherence remains a barrier to effective delivery of healthcare worldwide. Methods Twenty healthcare facilities (secondary or tertiary hospitals) belonging to the Korean Academy of Pediatric Allergy and Respiratory Diseases (KAPARD) participated. Questionnaires were given to patients currently receiving treatment in the form of inhalant useor oral intake or transdermal patch for mild to moderate asthma. Results A total of 1,838 patients responded to the questionnaire. Mean age was 5.98 ± 3.79 years (range: 0-18 years). With help from their caregivers, the percentage of patients that answered “taking as prescribed” was 38.04% for inhalant users, 50.09% for oral medication users and 67.42% for transdermal users. Transdermal patch users had significantly greater adherence compared to the other 2 groups (P < 0.001). The 34.15% of inhalant users, 70.33% of oral medication users and 93.00% of transdermal patch users felt that their medication delivery system was “Easy” or “Very easy” to use (P < 0.001). “Method of administration” was deemed to be the most difficult part of the treatment regimen to follow, and 76.7% of patients preferred once-daily administration (i.e., “Frequency of administration”). Conclusions Asthma medication adherence in young children was found to be better in the transdermal patch group. This may be due to requiring fewer doses and easy to follow instructions. From an adherence point of view, the transdermal patch seems more useful for long-term asthma control in children compared to oral or inhaled medicine.

Abstract
Background A US Food and Drug Administration (FDA)-approved drug methacholine chloride (Provocholine®) was recently introduced to Korea where it is now widely used in clinical practice. We aimed to evaluate the prevalence, risk factors and cutoff value of bronchial hyperresponsiveness (BHR) to Provocholine in 7-year-old children. Methods Six hundred and thirty-three children from the Panel Study on Korean Children who visited 16 regional hospitals were evaluated. Skin prick tests, spirometry and bronchial provocation tests for Provocholine as well as a detailed history and physical examinations were performed. The bronchial provocation test was reliably performed on 559 of these children. Results The prevalence of ever-diagnosed asthma via medical records was 7.7%, and that of current asthma (wheezy episode in the last 12 months + diagnosed asthma by physicians) was 3.2%. The prevalence of BHR to Provocholine was 17.2% and 25.8%, respectively, for a PC20 < 8 and < 16 mg/mL. The risk factors for BHR (PC20 < 16 mg/mL) were atopic dermatitis diagnosis and current dog ownership, whereas those for current asthma were allergy rhinitis diagnosis, a history of bronchiolitis before the age of 3, recent use of analgesics/antipyretics and maternal history of asthma. The BHR prevalence trend showed an increase along with the increased immunoglobulin E (IgE) quartile. The cutoff value of PC20 for the diagnosis of current asthma in children at age 7 was 5.8 mg/mL (sensitivity: 47.1%, specificity: 87.4%). Conclusions BHR to Provocholine (PC20 < 8 mg/mL) was observed in 17.2% of 7-year-olds children from the general population and the cutoff value of PC20 for the diagnosis of current asthma was 5.8 mg/mL in this age group. The risk factors for BHR and current asthma showed discrepancies suggesting different underlying mechanisms. Bronchial provocation testing with Provocholine will be a useful clinical tool in the future.

Abstract
Anthracyclines, such as doxorubicin, are effective anticancer drugs composed of a tetracyclic polyketide aglycone and one or more deoxysugar moieties, which play a critical role in their biological activity. A facile one-pot combinatorial biosynthetic system was developed for the generation of a range of glycosylated derivatives of anthracyclines. Cocultivation of Streptomyces venezuelae mutants producing two anthracycline aglycones with eight different nucleotide deoxysugar-producing S. venezuelae mutants that coexpress a substrate-flexible glycosyltransferase led to the generation of 16 aklavinone or ε-rhodomycinone glycosides containing diverse deoxysugar moieties, seven of which are new. This demonstrates the potential of the one-pot combinatorial biosynthetic system based on cocultivation as a facile biological tool capable of combining diverse aglycones and deoxysugars to generate structurally diverse polyketides carrying engineered sugars for drug discovery and development.

Abstract
This study was performed to investigate the association between maternal lutein intake and lutein concentrations in human milk among exclusive breast-feeding and mixed-feeding groups of lactating mothers in South Korea. From 99 women who were recruited from March to July 2015, dietary data and breast milk samples were obtained. The means of the daily lutein intakes and breast milk lutein concentrations in lactating mothers were 4.04 mg/day and 10.06 μg/dl, respectively, and they did not differ according to the type of breast-feeding. Breast milk lutein concentrations were positively correlated with the dietary lutein intake of lactating mothers after adjustment for the infant's age and supplement use by the lactating women (r=0.3337, P=0.0008). These correlations appeared in both groups. Further research is needed to identify whether breast milk lutein levels influence infant health, especially eye health.European Journal of Clinical Nutrition advance online publication, 25 May 2016; doi:10.1038/ejcn.2016.84.

Abstract
Cytomegalovirus (CMV) is currently the most common cause of congenital infection and the leading infectious cause of brain damage and hearing loss in children. Perinatal CMV infection rarely causes clinical manifestations in normal individuals and usually follows a benign course in immunocompetent infants. However, ~15-25% of infected preterm infants may develop pneumonia, hepatitis or sepsis-like illness, bradycardia, hepatosplenomegaly, distended bowel, anemia, or thrombocytopenia. Bronchiolitis obliterans (BO) is a rare, fibrosing form of chronic obstructive lung disease that follows severe insults to the lower respiratory tract and results in narrowing and/or complete obliteration of the small airways. In non-transplant children, the most common form of BO is a severe lower respiratory tract infection, especially of adenovirus. We experienced a case of a 37-day-old male who was diagnosed as BO on chest computed tomography (CT) after CMV pneumonia. To our best knowledge, this is the first case of BO caused by CMV pneumonia in a healthy infant.

Abstract
Imatinib mesylate is effective for chronic myeloid leukaemia and gastrointestinal tumours. We aimed to evaluate the pharmacokinetics of a 200-mg imatinib tablet compared to 2×100-mg imatinib tablets in order to meet the regulatory requirements for marketing in Korea.An open-label, randomized, single-dose, 2-period, 2-treatment cross-over study was conducted in 28 healthy Korean male volunteers. Subjects were administered a 200-mg imatinib tablet and 2×100-mg imatinib tablets under a fasting state according to a randomly assigned order with a 2-week wash-out period. Serial blood samples were collected up to 72 h post-dose. The pharmacokinetic parameters were calculated using non-compartmental methods.A total of 28 subjects were enrolled and 23 subjects completed the study. There were no serious adverse events during the study. 23 mild to moderate adverse events were reported (11 events with 200-mg imatinib vs. 12 events with 2×100-mg imatinib) and subjects recovered without sequelae. The Cmax value was 922.8±318.8 μg/L at 3.15 h for 200-mg imatinib tablet, and 986.3±266.0 μg/L at 2.91 h for the 2×100-mg imatinib tablet. The AUClast of 200-mg and 2×100-mg tablets were 13 084.3±39.1 and 14 131.7±3 826.2 h · μg/L, respectively. The geometric mean ratios (90% confidence intervals) for Cmax and AUClast were 0.9121 (0.8188, 1.0161) and 0.9558 (0.8685, 1.0519), respectively.A newly developed 200-mg imatinib tablet was bioequivalent to 2×100-mg imatinib tablets in healthy Korean subjects. A single-dose of either of the 2 formulations was generally well tolerated.

Abstract
WHAT IS KNOWN AND OBJECTIVE Sarpogrelate is a selective 5-hydroxytryptamine receptor subtype 2A antagonist that inhibits platelet aggregation and vasoconstriction. The aim of this study was to compare the pharmacokinetics of a sarpogrelate controlled-release formulation (CR) with those of the immediate-release formulation (IR). The effect of food on the pharmacokinetics of CR sarpogrelate was also evaluated. METHODS A randomized, open-label, 3-period, 3-treatment crossover study was conducted in 50 healthy male subjects. Subjects were allocated into one of six sequence groups. In one period, a 100-mg IR formulation was administered three times at 6-h intervals, and in the other two periods, a 300-mg CR formulation was administered once to fasting and once to fed subjects. Each period was separated by a 7-day washout period. Serial blood samples were collected up to 24 h after the first drug administration in each period. The plasma concentrations of sarpogrelate were analysed by liquid chromatography-tandem mass spectrometry. Pharmacokinetic parameters were calculated by non-compartmental methods. RESULTS AND DISCUSSION After the administration of the IR formulation, the plasma concentration reached a peak at 0·48 h and the drug was eliminated with a half-life (t1/2 ) of 0·7 h. After administration of the CR formulation, the plasma concentration reached a peak at 0·5 h and the drug was eliminated with a t1/2 of 3·23 h. The geometric mean ratios (CR/IR) for sarpogrelate area under the plasma concentration-time curve (AUC) and the maximum plasma drug concentration (Cmax) were 1·2040 (90% confidence interval (CI): 1·0992-1·3188) and 0·9462 (90% CI: 0·8504-1·0529). When CR was administered to fed subjects, the time to peak concentration was prolonged to 3·97 h and t1/2 was shortened to 1·45 h. The geometric mean ratios (fasting/fed) for sarpogrelate AUC and Cmax were 0·8573 (90% CI: 0·7687-0·9561) and 0·6452 (90% CI: 0·5671-0·7341). WHAT IS NEW AND CONCLUSION After the administration of CR and IR formulations of the same daily dose of sarpogrelate hydrochloride, the overall systemic exposure was slightly higher for the CR than for the IR formulation, whereas peak concentration was comparable between the two formulations. Food reduced the bioavailability of sarpogrelate CR.

Abstract
PURPOSE We previously reported that asthmatics had lower anti-serotype-specific pneumococcal polysaccharide antibody levels than non-asthmatics, and the T-helper 2 (Th2) immune profile was associated with suboptimal pneumococcal polysaccharide antibody. Our objective was to determine the influence of asthma status on anti-pneumococcal protein antigen antibody levels. METHODS We conducted a cross-sectional study, which enrolled 16 children and adults with asthma and 14 subjects without asthma. Asthma was ascertained by predetermined criteria. Serum IgG antibody levels to pneumococcal surface protein A (PspA), pneumococcal surface protein C (PspC), pneumococcal choline-binding protein A (PcpA), and pneumolysin (PLY) were measured by enzyme-linked immunosorbent assays (ELISA). These antibody levels were compared between asthmatics and non-asthmatics. The Th2 immune profile was determined by IL-5 secretion from PBMCs cultured with house dust mite (HDM) and staphylococcal enterotoxin B (SEB) at day 7. The correlation between the anti-pneumococcal antibody levels and the Th2-HDM and SEB-responsive immune profile was assessed. RESULTS Of the 30 subjects, 16 (53%) were male and the median age was 26 years. There were no significant differences in anti-PspA, anti-PspC, anti-PcpA, and anti-PLY antibody levels between asthmatics and non-asthmatics. The Th2 immune profile was inversely correlated with the anti-PspC antibody levels (r = -0.53, p = 0.003). This correlation was significantly modified by asthma status (r = -0.74, p = 0.001 for asthmatics vs. r = -0.06, p = 0.83 for non-asthmatics). Other pneumococcal protein antibodies were not correlated with the Th2 immune profile. CONCLUSION No significant differences in the anti-pneumococcal protein antigen antibody levels between asthmatics and non-asthmatics were found. Asthma status is an important effect modifier determining the negative influence of the Th2 immune profile on anti-PspC antibody levels.

Abstract
We report an unusual presentation of ganglioneuroblastoma with features of dilated cardiomyopathy in a 22 month old girl. She was admitted with cardiomegaly; during echocardiography a suspicious abdominal mass was detected by chance. Further imaging studies, including abdominal ultrasonography and spiral computed tomography, revealed a solid mass originating in the right adrenal gland. Metabolic studies and pathological findings were compatible with ganglioneuroblastoma. Following tumour removal and supportive therapy for cardiomyopathy, her clinical condition and laboratory findings improved. Although ganglioneuroblastoma with features of dilated cardiomyopathy is rare, because neurogenic tumours may be involved in its development, measurement of catecholamines in children with dilated cardiomyopathy is strongly recommended.

Abstract
SKI 306X is a purified extract from a mixture of three oriental herbal medicines (Clematis mandshurica, Trichosanthes kirilowii and Prunella vulgaris) that have been widely used for the treatment of inflammatory diseases such as lymphadenitis and arthritis in far East Asia. A double-blind, controlled study was performed to evaluate the efficacy and safety of SKI 306X with placebo in 96 patients with classical osteoarthritis of the knee. Patients were randomized to four treatment groups: placebo, 200 mg, 400 mg and 600 mg of SKI 306X t.i.d.. Clinical efficacy and safety were evaluated for 4 weeks continuous treatment. SKI 306X demonstrated its clinical efficacy, as assessed by 100 mm visual analogue scale (VAS), Lequesne index and patients' and investigators opinion of the therapeutic effect compared with placebo (p<0.01). No significant adverse events were observed in patients treated with SKI 306X. This study demonstrated that SKI 306X, a new herbal anti-arthritic agent provided clinical efficacy in patients with osteoarthritis.

Abstract
We investigated the effects of the aqueous extract of Salviae radix root (SRRAE) on immediate allergic reactions. SRRAE inhibited by 72.7% passive cutaneous anaphylaxis activated by anti-dinitrophenyl (DNP) immunoglobulin E (IgE). SRRAE dose dependently inhibited histamine release and tumor necrosis factor-alpha production from the rat peritoneal mast cells (RPMCs) by anti-DNP IgE. However, SRRAE showed no significant inhibitory effect on compound 48/80-induced systemic allergic reaction and histamine release from RPMCs. The level of cAMP in RPMCs, when SRRAE was added, significantly increased compared with that of a normal control. These results indicate that SRRAE may contain compounds with actions that inhibit anti-DNP IgE-induced mast cell degranulation in rats.

Abstract
Nucleoside diphosphate kinases (NDP kinases), products of the nm23 gene, catalyze the transfer of the terminal phosphate group of the nucleoside triphosphate to the corresponding diphosphate and may be involved in tumor metastasis suppression, development, and signal transduction. NDP kinase from various sources including human erythrocytes, rat brain tissue and E. coli strain BL21 transformed with pET3C expression plasmids containing nm23-H1 or nm23-H2, were purified in one step to homogeneity using ATP-sepharose affinity column chromatography. This method was applicable for the purification of various NDP kinases which show the same enzymatic activity and immunodetection, but have various molecular weight and quaternary structures.
