This study was attempted to clarify sociopsychiatric characteristics according to the class of psychoactive substances which were classified into 8 groups such and methamphetamin, cocaine, inhalants(bond/gas), dextromethorphan(Romilar), sedatives marijuana, analgesics and etc. The data of the study were collected from 134 psychoactive substance abusers(89men, 45women), who had admitted to SNMH during past 5 years. The results were as follows ; 1) The mean age of patients was 26.5±9.6 years and according to the class of psychoactive substance, inhalant and dextromethorphan abusers were significantly younger than sedatives and analgesics abusers(P〈0.01). 2) 43.1% of patients were grown up in broken family until puberty and 27.9% of married patients showed unstable marital state such as a divorce or seperation. 3) 41.4% of patients had past history of delinquent behavior and especially, inhalants and dextromethorphan abusers had more past history of delinquent behavior than sedatives and analgesics abusers(P〈0.01). 4) The main motive of mitiation of psychoactive substance was peer pressure, relief of psysical symptoms, curiosity in that order. 75% of inhalants abusers were itiated by peer pressure, but most of sedatives and analygesics abusers used it for the purpose of relieving of physical symptoms, and methamphetamine abusers used it mainly due to peer pressure or for the purpose of increasing sexual plesure(P〈0.01). 5) 57.5% of patients reported the experience of unwanted response such as unpleasant hallucinatory state, loss of control, and psychotic state after use of psychoactive substances. Especially the unwanted respose was reported more frequently in methamphetamin and inhalants abusers. 6) 38.5% of patients abused more than two classes of psychoactive substances, and their significant combination types were not found but inhalant-dextromethorphan, analygesics-sedatives and methamphetamine-marijuana combination types were relatively common.

The present study aims to explore the effects of applying spheroid-combined stimulating therapy on body composition. For this aim. 20 persons were selected as subjects and 10 of them each were assigned to the experimental group and control group, respectively. The experimental group was applied a 12-week combined stimulating therapy and changes in physical constitution of the members were measured before application and 4, 8 and 12 weeks after application. From the study, following conclusions could be drawn: First, body weights of the experimental group decreased from 59.9kgs before application of the spheroid-combined stimulating therapy to 57.2kgs 12 weeks after application, no significant but 4.51% change. Second, body fats of the experimental group changed from 18.8kgs before application to 16.4kgs 12 weeks after application, no significant but 12.77% reduction. Third, % fats of the experimental group decreased from 31.2% before application to 28.6% 12 weeks after application, no significant change but 8.33% reduction. Fourth, body mass index(BMI) of the experimental group decreased from 23.23 kg/㎡ before application of the therapy to 21.43kg/㎡ after application, no significant but 8.03% reduction. As seen above, the 12-week application of the spheroid-combined stimulating therapy produced no significant changes in physical constitution as physical exercise did, but improved physical constitution by reducing certain amount of boy weight, body fat, % fat and BMI. In order to detect more positive and significant changes in physical constitutions, continued studies and clinical experiments should be performed to more diverse subjects using technically reinforced equipment for spheroid-combined stimulating therapy.

Background: Colorectal polyps are the most common cause of isolated hematochezia in children, which requires a colonoscopy for diagnosis. We aimed to investigate the potential utility of fecal calprotectin (FC) in assessing colorectal polyps detected by colonoscopy among children presenting with isolated hematochezia. Methods: Pediatric patients of the age of < 18 years who had undergone both colonoscopy and FC tests for isolated hematochezia from June 2016 to May 2020 were included in the present multicenter, retrospective, cross-sectional study. Comparative analysis was conducted between major causes of isolated hematochezia and FC cut-offs for discriminating colorectal polyps were explored. Results: A total 127 patients were included. Thirty-five patients (27.6%) had colorectal polyps, followed by anal fissure (14.2%), ulcerative colitis (UC; 12.6%), and others. A significant difference in FC levels was observed between patients with colorectal polyps (median, 278.7 mg/kg), anal fissures (median, 42.2 mg/kg), and UC (median, 981 mg/ kg) (P < 0.001). According to receiver operating characteristic curve analysis, among patients diagnosed with colorectal polyp or anal fissure, the most accurate FC cut-off for discriminating colorectal polyps from anal fissures on colonoscopy was 225 mg/kg (sensitivity, 59.4%; specificity, 94.4%; positive predictive value [PPV], 95.0%; negative predictive value [NPV], 56.7%; area under the curve [AUC], 0.8; 95% confidence interval [CI], 0.678–0.923; P < 0.001), while among patients diagnosed with colorectal polyp or UC, the most accurate FC cut-off for discriminating colorectal polyps from UC on colonoscopy was 879 mg/kg (sensitivity, 81.2%; specificity, 56.2%; PPV, 78.8%; NPV, 60.0%; AUC, 0.687; 95% CI, 0.521–0.852; P < 0.001). Conclusion: FC may assist in assessing the cause of lower gastrointestinal tract bleeding in children who present with isolated hematochezia.

Eu Suk Kim,Bum Sik Chin,강창경,Nam Joong Kim,Yu Min Kang,Jae-Phil Choi,Dong Hyun Oh,Jeong-Han Kim,Boram Koh,Seong Eun Kim,Na Ra Yun,Jae Hoon Lee,Jin Yong Kim,Yeonjae Kim,Ji Hwan Bang,송경호,Hong Bin Kim,Ki- 대한의학회 2020 Journal of Korean medical science Vol.35 No.13

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected pneumonia emerged in Wuhan, China in December 2019. In this retrospective multicenter study, we investigated the clinical course and outcomes of novel coronavirus disease 2019 (COVID-19) from early cases in Republic of Korea. Methods: All of the cases confirmed by real time polymerase chain reaction were enrolled from the 1st to the 28th patient nationwide. Clinical data were collected and analyzed for changes in clinical severity including laboratory, radiological, and virologic dynamics during the progression of illness. Results: The median age was 40 years (range, 20–73 years) and 15 (53.6%) patients were male. The most common symptoms were cough (28.6%) and sore throat (28.6%), followed by fever (25.0%). Diarrhea was not common (10.7%). Two patients had no symptoms. Initial chest X-ray (CXR) showed infiltration in 46.4% of the patients, but computed tomography scan confirmed pneumonia in 88.9% (16/18) of the patients. Six patients (21.4%) required supplemental oxygen therapy, but no one needed mechanical ventilation. Lymphopenia was more common in severe cases. Higher level of C-reactive protein and worsening of chest radiographic score was observed during the 5–7 day period after symptom onset. Viral shedding was high from day 1 of illness, especially from the upper respiratory tract (URT). Conclusion: The prodromal symptoms of COVID-19 were mild and most patients did not have limitations of daily activity. Viral shedding from URT was high from the prodromal phase. Radiological pneumonia was common from the early days of illness, but it was frequently not evident in simple CXR. These findings could be plausible explanations for the easy and rapid spread of SARS-CoV-2 in the community.

( Yu Bin Kim ),( Shan Randima Nawarathne ),( Hyun Min Cho ),( Jun Seon Hong ),( Jung Min Heo ),( Jiseon Son ) 한국축산학회 2022 한국축산학회지 Vol.64 No.1

The current study was conducted to evaluate the effect of calcium-enriched fatty acid supplementation on the growth performance, blood metabolites, intestinal morphology, carcass traits, and nutrient digestibility of broilers subjected to chronic heat stress. A total of 210 one-day-old broiler chicks (40.12 ± 0.25 g) were randomly allocated to one of five dietary treatments, to obtain six replicates per treatment. Broilers were subjected to chronic heat stress from day 21 to day 35, post-hatching, at 34℃ for 9 h per day. The body weight (BW) and feed intake of the experimental broilers were recorded weekly, and the average daily gain (ADG) and feed conversion ratio (FCR) were calculated accordingly. Rectal temperature was measured to compare the basal body temperatures between individuals, and blood samples were collected on days 21 and 35 to evaluate basal body temperature, serum total cholesterol, and the triglyceride content of the broilers. On days 21 and 35, one broiler from each cage (n=6) was euthanized to measure carcass trait parameters, nutrient digestibility in digesta, and intestinal morphology. On days 14, 28, and 35, the broilers fed 2.0% calcium-enriched fatty acids had higher BW (p < 0.05) than those fed the other diets. However, no differences (p > 0.05) were found in the average daily feed intake (ADFI) between dietary treatments over the 35 experimental days. On the other hand, on day 21, post-hatching, the broilers fed the 2.0% calcium-enriched fatty acid diet had improved (p < 0.05) dietary feed efficiencies compared to the other treatments. On day 28, the broilers fed the 5.0% of calcium-enriched fatty acid diet also had higher (p < 0.05) dietary feed efficiencies than those fed with the other dietary treatments. No effects (p > 0.05) on carcass weight, nutrient digestibility, intestinal morphology, or blood parameters were found between broilers fed with dietary treatments. This study demonstrated that the inclusion of an additive, containing 2.0% calcium-enriched fatty acid, to broiler diet could ameliorate the negative growth performance of broilers; and no interaction (p > 0.05) was observed between the calcium-enriched fatty acid and nutrient digestibility, digestive anatomy, blood metabolism, and carcass traits of broilers subjected to chronic heat stress conditions for 35 days post-hatching.

Kim, Yu Bin,Tang, Chih Lung,Koo, Ja Wook The Korean Pediatric Society 2018 Clinical and Experimental Pediatrics (CEP) Vol.61 No.1

Purpose: To determine the relationship between vaginal reflux (VR) and urinary tract infection (UTI) in female children aged <36 months. Methods: A single center retrospective study was performed for 191 girls aged <36 months, with a diagnosis of febrile UTI, who underwent a voiding cystourethrography (VCUG) for assessment of vesicoureteral reflux (VUR) at Sanggye Paik Hospital. Fifty-one girls, who underwent VCUG for assessment of congenital hydronephrosis or renal pelvis dilatation, without a UTI, formed the control group. The correlation between the presence and grade of VR and UTI was evaluated. Results: The prevalence rate of VR was higher in the UTI (42.9%) than control (13.7%) group (P<0.05), with a higher VR severity grade in the UTI (mean, 0.64) than control (mean, 0.18) group (P<0.05). On subanalysis with age-matching (UTI group: n=126, age, $5.28{\pm}2.13months$; control group: n=22, age, $4.79{\pm}2.40months$; P=0.33), both VR prevalence (43.65% vs. 18.18%, P<0.05) and grade (0.65 vs. 0.22, P<0.05) remained higher in the UTI than control group. Presence and higher grade of VR were associated with UTI recurrence (P<0.05). VR was correlated to urosepsis (P<0.05). The renal defect rate of patients with VR (VR [+]/VUR [+]) was not different from that of patients without VR (74% vs. 52%, P=0.143) in the VUR group; however, it was higher than that of VR (+)/VUR (-) patients (74% vs. 32%, P=0.001). If a child with VR (+)/VUR (+) is exposed to a UTI, the risk of renal defect increases. Conclusion: Occurrence of VR is associated with UTI recurrence and urosepsis in pediatric female patients.

Neutralizing antibodies targeted at the receptor-binding domain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein have been developed and now under evaluation in clinical trials. The US Food and Drug Administration currently issued emergency use authorizations for neutralizing monoclonal antibodies in non-hospitalized patients with mild to moderate coronavirus disease 2019 (COVID-19) who are at high risk for progressing to severe disease and/or hospitalization. In terms of this situation, there is an urgent need to investigate the clinical aspects and to develop strategies to deploy them effectively in clinical practice. Here we provide guidance for the use of anti-SARS-CoV-2 monoclonal antibodies for the treatment of COVID-19 based on the latest evidence.

Cordycepin Accelerates Osteoblast Mineralization and Attenuates Osteoclast Differentiation In Vitro

Yu, Su-Bin,Kim, Hye-Jin,Kang, Hae-Mi,Park, Bong-Soo,Lee, Ji-Hye,Kim, In-Ryoung Hindawi 2018 Evidence-based Complementary and Alternative Medic Vol.2018 No.-

<P>Bone homeostasis destruction is triggered by the uncontrolled activity of osteoblasts and osteoclasts. Targeting both the regulation of bone formation and resorption is a promising strategy for treating bone disorders. Cordycepin is a major component of Chinese caterpillar fungus<I> Cordyceps militaris</I>. It exerts a variety of biological actions in various cells and animal models. However, its function on bone metabolism remains unclear. In the present study, we discovered a dual-action function of cordycepin in murine MC3T3-E1 and RAW264.7 cells. MC3T3-E1 cells were cultured in an osteogenic medium in the presence of 1 <I>μ</I>M cordycepin for up two weeks. Cordycepin was used for effects of osteoblast and osteoclast differentiation. Cell viability was measured using the MTT assay. Osteoblast differentiation was confirmed by alizarin red staining, ALP activity, western blot, and real-time PCR. Osteoclast differentiation and autophagic activity were confirmed via TRAP staining, pit formation assay, confocal microscopy, western blot, and real-time PCR. Cordycepin promoted osteoblast differentiation, matrix mineralization, and induction of osteoblast markers via BMP2/Runx2/Osterix pathway. On the other hand, RAW264.7 cells were differentiated into osteoclast by RANKL treatment for 72 h. 1 <I>μ</I>M cordycepin significantly inhibited RANKL-induced osteoclast formation and resorption activity through disturbing the actin ring-formatted sealing zone and activating cathepsin K and MMP9. These findings indicate that cordycepin might be an innovative dual-action therapeutic agent for bone disease caused by an imbalance of osteoblasts and osteoclasts.</P>
