PURPOSE: This study aimed to investigate the characteristics of poisoning drug ingested by younger children, and to compare the clinical outcome by drug forms.METHODS: This was a retrospective analysis based on medical records from the Emergency Department based Injury In-depth Surveillance (EDIIS) registry in Korea from January to December 2015. Patients aged 7 years or younger visiting the emergency department (ED) with drug poisoning were included. We classified the forms of drugs as tablets or syrup, and analyzed the characteristics by size, color, and shape. In addition, clinical outcomes and ED length of stay were compared according to the drug forms.RESULTS: A total of 308 cases were collected, and 202 patients finally were analyzed. Tablets and capsules (TACs) were more common than syrup (67.3% vs. 32.7%). Regarding clinical outcomes, patients who took TACs had higher admission rate (17.6% vs. 7.6%, P = 0.040) without a significant difference in ED length of stay compared to those who took syrups. While commonly ingested drugs in TACs were hormones, sedative and analgesics, frequent drugs in syrup were antihistamines and cold drugs. In 136 case of TACs, median long and short axes were 0.85 cm (interquartile range [IQR], 0.7–1.1 cm) and 0.72 cm (IQR, 0.59–0.82 cm), respectively. Chromatic TACs were 80 cases (58.8%) and more common than achromatic TACs. Round shapes were preferred than angular ones (96.3% vs. 3.7%).CONCLUSION: In younger children poisonings, the TACs showed higher incidence and admission rate compared to syrups. Especially, chromatic TACs and round shapes were preferred. Therefore, drugs with these characteristics need to be stored more carefully.

Mohammad Saydur RAHMAN ; Young Sang KOH
Journal of Bacteriology and Virology 2018;48(3):109-112
Nowadays antibiotic resistance is a worldwide serious problem that mainly affects public health. Omadacycline is a unique antibiotic which has two available dosage forms such as intravenous (IV) and oral that development for community-acquired bacterial infectious disease treatment. It is a modified form of older tetracycline at C-9 aminomethyl substituent of 6-member core ring of tetracycline. Modification form shows its activity against efflux pump and ribosomal protein protection mechanism of tetracycline resistance. Generally, omadacycline is effective against methicillin-resistant S. aureus (MRSA), Streptococcus pneumoniae, vancomycin-resistant Enterococcus (VRE), Legionella and Chlamydia spp. Efficacy, safety and tolerability profile of omadacycline those compares with recent antibiotics shows that omadacycline is less resistant than others. One derivative from tetracycline derivatives is 9-neopentylaminomethylminocycline called omadacycline was discovered and ongoing phase III clinical experiments as a therapy for acute bacterial skin and skin structure infections (ABSSSI) as well as community-acquired bacterial pneumonia (CABP). Omadacycline seems to be a strong drug candidate for future promising new antibacterial agent that is effective against ABSSSI and CABP.

The posaconazole tablet formulation was developed to have improved bioavailability compared to the oral suspension. Here, we compared posaconazole plasma concentration (PPC) with the posaconazole oral suspension versus the tablet in Korean patients undergoing remission induction chemotherapy for hematologic malignancies. PPC was measured at 3, 8, and 15 days of treatment with the oral suspension (174 patients) or the tablet (40 patients). At all time-points, mean PPC was significantly higher with the tablet compared to the oral suspension. Our findings suggest that posaconazole tablets generate an optimal PPC earlier and in more patients than the oral suspension among Korean patients.

Except blank and model group, the other groups were paste ointment for 7 days, and one time a day, matrix control group were pasted isodose blank matrix gel patch. Pain threshold were tested at 30, 60, 90 and 120 min after the last ad-ministration. Hot plate test were performed by injection of 5% formalin for 20 µL on right hindfoot sole after the last administration. The cumulative time of mice licking right rear foot were observed at stage of I and II, and content of IL-1, TNF-α were tested by ELISA method. Differences of weight between right and left ears were measured by ear swelling method and anti-inflammation experiment.
RESULTSIn hot plate test at 90 min, pain threshold in equivalent dosage of Dinggui gel paste group was (24.87 ± 14.67) s and (15.28 ± 8.23) s in model group; (26.33 ± 15.45) s in high dosage of Dinggui gel paste group and (15.31 ± 5.02) s in model group at 120 min in hot plate test, there were no statistical differences between two groups. Pain period at stage I, licking cumulative time in high dosage of Dinggui gel paste group was (66.70 ± 22.83) s and (101.80 ± 33.65) s in model group,and had significant differences between two groups; there were statistical differences in licking cumulative time at stage I of pain period among high dosage of Dinggui gel paste group (51.30 ± 43.60)s, equivalent dosage of Dinggui gel paste group (64.00 ± 47.27) sand model group (109.50 ± 36.78) s. Content of IL-1 in model group was (28.70 ± 8.24) ng/L and (13.33 ± 2.20) ng/L in high dosage of Dinggui gel paste group, there was obvious meaning between two groups; There were significant differences in TNF-α content among model group (93.60 ± 23.65) ng/L,high dosage of Dinggui gel paste group (63.21 ± 10.54)ng/L and equivalent dosage of Dinggui gel paste group (72.69 ± 16.26) ng/L; while there were no statistical meaning in ear swelling degree among model group (5.73 ± 0.80) mg,high dosage of Dinggui gel paste group (5.42 ± 0.68) mg and equivalent dosage of Dinggui gel paste group (4.98 ± 1.52) mg.
CONCLUSIONDinggui gel paste could increase pain threshold, reduce licking accumulative time, and decrease ear swelling degree, and relief pain by regulating level of TNF-α and IL-1.

Bi-yuan-ling granule (BLG) is a traditional Chinese medicine compound composed mainly of baicalin and chlorogenic acid. It has been demonstrated to be clinically effective for various inflammatory diseases such as acute rhinitis, chronic rhinitis, atrophic rhinitis and allergic rhinitis. However, the underlying mechanisms of BLG against these diseases are not fully understood. This study aimed to explore the anti-inflammatory and analgesic activities of BLG, and examine its protective effects on mouse acute lung injury (ALI). The hot plate test and acetic acid-induced writhing assay in Kunming mice were adopted to evaluate the pain-relieving effects of BLG. The anti-inflammatory activities of BLG were determined by examining the effects of BLG on xylene-caused ear swelling in Kunming mice, the cotton pellet-induced granuloma in rats, carrageenan-induced hind paw edema and lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. The results showed that BLG at 15.5 mg/g could significantly relieve the pain by 82.5% (P<0.01) at 1 h after thermal stimulation and 91.2% (P<0.01) at 2 h after thermal stimulation. BLG at doses of 7.75 and 15.5 mg/g reduced the writhing count up to 33.3% (P<0.05) and 53.4% (P<0.01), respectively. Additionally, the xylene-induced edema in mice was markedly restrained by BLG at 7.75 mg/g (P<0.05) and 15.5 mg/g (P<0.01). BLG at 5.35 and 10.7 mg/g significantly reduced paw edema by 34.8% (P<0.05) and 37.9% (P<0.05) at 5 h after carrageenan injection. The granulomatous formation of the cotton pellet was profoundly suppressed by BLG at 2.68, 5.35 and 10.7 mg/g by 15.4%, 38.2% (P<0.01) and 58.9% (P<0.001), respectively. BLG also inhibited lung W/D ratio and the release of prostaglandin E2 (PGE2) in ALI mice. In addition, the median lethal dose (LD50), median effective dose (ED50) and half maximal inhibitory concentration (IC50) of BLG were found to be 42.7, 3.2 and 12.33 mg/g, respectively. All the findings suggest that BLG has significantly anti-inflammatory and analgesic effects and it may help reduce the damage of ALI.

OBJECTIVETo determine the effective dosage and formulation of agkistrodon in collagen-induced arthritis (CIA) rats.
METHODSCIA was induced by injection of collagen in complete/incomplete Freund's adjuvant. Agkistrodon decoction, agkistrodon powder, and agkistrodon wine were administered daily starting from the onset of arthritis. Paw swelling degree was measured by using a volume-measuring instrument every 7 days after primary immunization. Arthritis index was measured and calculated using the "five scoring method" every 7 days. The levels of serum interleukin-1ß (IL-1ß) and type II collagen IgG antibodies were detected by enzyme-linked immunosorbent assay. Finally, all ankles were removed, and X-ray radiography was performed with In-vivo Imaging System FX. Samples were counterstained with hematoxylin and eosin for analysis.
RESULTSAmong the various dosage formulations of agkistrodon, high-dose powder, which was equivalent to an amount of 6 g/day in adults, showed better effects on the inhibition of joint swelling and reduction of arthritis index score. The relatively low levels of serum IL-1 and anti-type II collagen IgG antibodies, as well as the X-ray radiography and pathology results, further proved the superiority of the high-dose powder over the other formulations. The effect of decoction on inhibiting joint swelling was inversely proportional to the dosage. Other effects, such as reduction of arthritis index score and the levels of serum IL-1 and anti-type II collagen IgG antibodies, were directly proportional to the dosage. While the use of large dose agkistrodon wine led to negative effects.
CONCLUSIONThese data highlight the potential function of high-dose agkistrodon powder, which was equivalent to an amount of 6 g/day in adults. The powder can quickly relieve the symptoms of rheumatoid arthritis and prevent aggravation of disease, especially during the early period.

beta-Lapachone has drawn increasing attention as an anti-inflammatory and anti-cancer drug. However, its oral bioavailability has not been yet assessed, which might be useful to develop efficient dosage forms possibly required for non-clinical and clinical studies and future market. The aim of the present study was thus to investigate pharmacokinetic properties of beta-lapachone as well as its first-pass metabolism in the liver, and small and large intestines after oral administration to measure the absolute bioavailability in rats. A sensitive HPLC method was developed to evaluate levels of beta-lapachone in plasma and organ homogenates. The drug degradation profiles were examined in plasma to assess the stability of the drug and in liver and intestinal homogenates to evaluate first-pass metabolism. Pharmacokinetic profiles were obtained after oral and intravenous administration of beta-lapachone at doses of 40 mg/kg and 1.5 mg/kg, respectively. The measured oral bioavailability of beta-lapachone was 15.5%. The considerable degradation of beta-lapachone was seen in the organ homogenates but the drug was quite stable in plasma. In conclusion, we suggest that the fairly low oral bioavailability of beta-lapachone may be resulted from the first-pass metabolic degradation of beta-lapachone in the liver, small and large intestinal tracts and its low aqueous solubility.

PURPOSE: It has been reported in several for factors on the drug compliance of patients, number of drug being taken, symptom, and pharmaceutical dosage form. However, Studies of drug compliance by dosing methodologies of tamsulosin, finasteride combination therapy and symptom relief for benign prostatic hyperplasia has not been performed. Therefore, we studied for symptom and differences in medication adherence in method of administration of tamsulosin, finasteride combination therapy. MATERIALS AND METHODS: The groups were consisted in need of combination therapy of tamsulosin, finasteride on benign prostatic hyperplasia, one had packaged both drugs together (Group A, n=30) and the other were individually packaged both agents (Group B, n=30). International Prostatic Symptom Score (IPSS) were checked on first, 4weeks, and 8weeks. The evaluation was carried out of medicine compliance by checking the number of drugs 4weeks-interval. which was every 4weeks during 8weeks. RESULTS: The properties other than the PSA in both groups, there was no statistically significant differences between patients. In first 4weeks, drug compliance of each Group A and B had tamsulosin 82.6%, 93.3% (p=0.033), finasteride 80.1%, 93.3% (p=0.042), and last 4weeks tamsulosin 80.6%, 93.7% (p=0.013), finasteride 79.5%, 93.7% (p=0.002) were checked. Group C, D had 81.4%, 96.4% (p=0.021) on 4weeks, 80.6%, 97.2% (p=0.011) on 8weeks. CONCLUSIONS: For co-administration of finasteride and tamsulosin are required in patients with benign prostatic hyperplasia, in order to enhance drug compliance, both tablets have to prescript together in one package to be taken at one time is useful.

To establish a multi-pretreatment method for the determination of aflatoxin B1, B2, G1, G2 in Chinese patent medicines, aflatoxins were analyzed by high performance liquid chromatography-fluorescence detector with post-column derivatization, after the multi-pretreatment of samples. The results showed that after the samples extracted with MeOH-H2O, dehydrated by anhydrous magnesium sulphate and sodium chloride, and finally purified by neutral alumina, the impurity interference of different sources in Chinese patent medicines matrix can be effectively removed, and the main peak can be nicely separated from the impurity peak. The detection limits were 0.25, 0.25, 0.50, 0.25 μg x L(-1) for AFB1, AFB2, AFG1, AFG2, respectively. The quantification limits were 1.00, 0.50, 1.00, 0.50 μg x L(-1), respectively. Aflatoxin B1, G1 showed a good linear relationship at a range of 1.0-50 μg x L(-1), aflatoxin B2, G2 at a range of 0.5-12.5 μg x L(-1) (R2 > 0.99). The average recovery was 80.40% - 108.6%. The present method is simple, reproducible with the reasonable recoveries and can be applied for the determination of aflatoxins in Chinese patent medicines.
