Objective: To evaluate the effects of maternal body mass index (BMI) and plurality on maternal and umbilical cord serum magnesium levels after antenatal magnesium sulfate treatment. Methods: This was a retrospective cohort analysis of 135 women treated with antenatal magnesium sulfate at less than 32 weeks of gestation between January 2012 and June 2018. Subjects were stratified into groups according to maternal BMI (group I [18.5–22.9 kg/m²], group II [23.0–24.9 kg/m²], and group III [≥25.0 kg/m²]) and plurality (singleton and twin). Univariable and multivariable analyses were performed to compare the umbilical cord serum magnesium levels between the groups. Results: Maternal serum magnesium levels were not significantly different between the maternal BMI groups and singleton and twin pregnancies. Umbilical cord serum magnesium levels were significantly different among the maternal BMI groups (3.3±1.2 mg/dL in group I, 3.3±1.2 mg/dL in group II, and 4.0±1.4 mg/dL in group III, P=0.003). The trend of increase in magnesium levels was statistically significant (P=0.001, Jonckheere-Terpstra test). Umbilical cord serum magnesium levels were not significantly different according to plurality. However, in the multivariable analysis, maternal BMI and plurality were not significantly associated with umbilical cord serum magnesium levels after adjusting for indication and total dose of magnesium sulfate treatment, gestational age at delivery, mode of delivery, neonatal sex, and birth weight. Conclusion Maternal BMI and plurality were not significantly associated with maternal or umbilical cord serum magnesium levels after exposure to antenatal magnesium sulfate treatment.

PURPOSE: The prognostic significance of tumor-infiltrating lymphocytes (TILs) has been determined in breast cancers. Interferons can affect T-cell activity through direct and indirect mechanisms. Myxovirus resistance A (MxA) is an excellent marker of interferon activity. Here,we evaluated TILs and MxA expression in human epidermal growth factor receptor 2 (HER2)–positive breast cancers. MATERIALS AND METHODS: Ninety cases of hormone receptor (HR)+/HER2+ tumors and 78 cases of HR–/HER2+ tumors were included. The TILs level was assessed using hematoxylin and eosin–stained full face sections, and MxA expressionwas evaluated by immunohistochemistrywith a tissue microarray. RESULTS: MxA protein expression was significantly higher in tumors with high histologic grade (p=0.023) and high levels of TILs (p=0.002). High levels of TILs were correlated with high histological grade (p=0.001), negative lymphovascular invasion (p=0.007), negative lymph node metastasis (p=0.007), absence of HR expression (p < 0.001), abundant tertiary lymphoid structures (TLSs) around ductal carcinoma in situ (p=0.018), and abundant TLSs around the invasive component (p < 0.001). High levels of TILs were also associated with improved disease-free survival, particularly in HR–/HER2+ breast cancers. However, MxA was not a prognostic factor. CONCLUSION: High expression of MxA in tumor cells was associated with high levels of TILs in HER2-positive breast cancers. Additionally, a high level of TILs was a prognostic factor for breast cancer, whereas the level of MxA expression had no prognostic value.

OBJECTIVES: This study was conducted in order to investigate characteristics of temperament, depression, anxiety, attention, and impulsivity in adult males with Attention Deficit/Hyperactivity Disorder (ADHD) and internet addiction tendency. METHODS: The survey participants were 181 (121 patients and 60 healthy control subjects) adult males older than 19 years of age in Chung-Ang University Hospital and Gongju National Hospital. Subjects were divided according to ADHD with internet addiction tendency (AI), pure adults with ADHD (AD), and healthy control subjects (HC). All groups completed the Adult ADHD Scale (AADHD), Wender-Utah ADHD Rating Scale (WUADHD), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), the Korean Version of Young Internet Addiction Scale (YIAS-K), Barratt Impulsiveness Scale (BIS) and Temperament Character Inventory-Revised Short version for identification of relationship between ADHD and internet addiction tendency. RESULTS: AI groups were found to have higher AADHD, WUADHD, BDI, YIAS-K, and Novelty Seeking scores, compared to the AD and HC groups. The Cooperativeness score of the AI group was significantly lower than that of the AD group and HC group. The BAI and BIS scores of the AI group and AD group were significantly higher than those of the HC group. The Self-Directedness scores of the AI group and AD group were decreased, compared to the HC group. YIAS-K scores were partially related to BDI scores in the AI group. CONCLUSION: The results of this study indicate an association of higher score of BDI with internet addiction tendency in adult patients with ADHD. Management of temperament characteristics, depression, anxiety, attention, and impulsivity may be important for adults with ADHD and internet addiction tendency.

Intestinal giant-cystic disease (IGCD) of the Israel carp (Cyprinus carpio nudus) has been recognized as one of the most serious diseases afflicting inland farmed fish in the Republic of Korea, and Thelohanellus kitauei has been identified as the causative agent of the disease. Until now, studies concerning IGCD caused by T. kitauei in the Israel carp have been limited to morphological and histopathological examinations. However, these types of diagnostic examinations are relatively time-consuming, and the infection frequently cannot be detected in its early stages. In this study, we cloned the full-length 18S rRNA gene of T. kitauei isolated from diseased Israel carps, and carried out molecular identification by comparing the sequence with those of other myxosporeans. Moreover, conventional PCR and real-time quantitative PCR (qPCR) using oligonucleotide primers for the amplification of 18S rRNA gene fragment were established for further use as methods for rapid diagnosis of IGCD. Our results demonstrated that both the conventional PCR and real-time quantitative PCR systems applied herein are effective for rapid detection of T. kitauei spores in fish tissues and environmental water.

Synovial sarcoma (SS) is a malignant soft tissue tumor comprising 5-10% of all soft tissue sarcomas. This tumor normally occurs in the paraarticular regions of the extremities but is rare in head and neck sites. SS is sometimes difficult to diagnose because it can mimic benign lesions both clinically and radiologically. This paper presents a rare case of a SS of the buccal space of a 25-year old man. The histology examination and immunohistochemistry of the mass led to a diagnosis of synovial sarcoma. The patient was treated primarily with a surgical resection, followed by radiotherapy and chemotherapy. The follow up examination 17-months after surgery showed no signs of tumor relapse or metastasis.

In this study, we observed the alteration of choline signal intensity in hippocampus region of the depressive rat model induced by forced swimming test (FST). The purpose of this study was to evaluate the antidepressant efficacy in the depressive animal model using MR spectroscopy. Fourteen experimentally naive male Sprague-Dawley rats weighting 160~180 g were used as subjects. Drug injection group was exposed to the FST except for control group. The drugs were administered subcutaneously (SC) in a volume equivalent to 2 ml/kg. And three injections were administered 23, 5, and 1 h before beginning the given test. 1H MR spectra were obtained with use of a point resolved spectroscopy (PRESS) localization sequence performed according to the following parameters: repetition time, 2500 ms; echo time, 144 ms; 512 average; 2048 complex data points; voxel dimensions, 1.5x2.5x2.5 mm3; acquisition time, 25 min. There were no differences in NAA/Cr and Cho/Cr ratio between the right and the left hippocampus both normal control rats and antidepressant-injected rats. Also, no differences were observed in NAA/Cr and Cho/Cr ratio between the normal control rats and the antidepressant-injected rats both the right and the left hippocampus. In this study, we found the recovery of choline signals in the depressive animal model similar to normal control groups as injecting desipramine-HCl which was antidepressant causing anti-immobility effects. Thus, we demonstrated that MR spectroscopy was able to aid in evaluating the antidepressant effect of desipramine-HCl.

Hepatitis B virus (HBV) reactivation is the frequent complication after cytotoxic chemotherapy in HBsAg-positive non-Hodgkin's lymphoma (NHL) patients. Pre-chemotherapy viral load may be a risk factor and HBeAg-positive status is associated with increased viral load. The aim of this study was to investigate the long-term treatment outcome of lamivudine in preventing HBV reactivation and its associated morbidity according to HBeAg status. Twenty-four adult HBsAg-positive NHL patients were taken 100mg of lamivudine daily before the initiation of chemotherapy. The median duration of lamivudine therapy was 11.5 months (range: 1-54 months) and the median number of chemotherapy cycles was 6 (range: 1-16 cycles). The steroid containing chemotherapy regimens were used in 18 patients (75%), and the anti-CD20 monoclonal antibody containing chemotherapy regimen was used in 6 patients (25%). Four patients received autologous peripheral blood stem cell transplantation without resultant HBV reactivation. Hepatitis related to HBV reactivation was developed in 1 patient among 14 HBeAg-positive patients and no one among 10 HBeAg-negative. One patient developed HBV reactivation after lamivudine withdrawal, and 4 patients developed the YMDD (tyrosine-methionine-aspartate-aspartate) mutation during lamivudine therapy. There were no statistical differences in HBV reactivation rate during chemotherapy according to the HBeAg status. Our results demonstrate that lamivudine should be considered preemptively before the chemotherapy for all HBsAg-positive NHL patients to prevent HBV reactivation, regardless of pre-chemotherapy HBeAg status. Finally, compared with the chronic hepatitis B patients, similar rate of HBV reactivation after lamivudine withdrawal and development of YMDD mutation was observed in NHL patients.

BACKGROUND: Polycystic ovary syndrome (PCOS) is characterized by chronic anovulation and hyperandrogenism and this malady arises in 5~10% of reproductive women. There may be significant ethnic and racial variations in the clinical presentation of PCOS. The current study is aimed to define the clinical characteristics, including the metabolic features, of Korean women with PCOS. METHODS: We recruited 156 patients with PCOS and 252 healthy regular cycling women as controls between March 2003 and May 2006. The diagnosis of PCOS was made according to the criteria of the European Society of Human Reproduction and Embryology in 2003. The anthropometric measurements including weight, height, waist circumference, and physical examination for the modified Ferriman-Gallwey hirsutism scoring scale were performed. Reproductive hormones, blood lipids and standard 75g oral glucose tolerance tests were done to assess glucose tolerance and insulin sensitivity. RESULTS: Twenty six percent of the women with PCOS were obese and 6.4% of them had hirsutism. One of the 156 women (0.6%) with PCOS was newly diagnosed with diabetes mellitus and 25 of them (16.0%) had impaired glucose tolerance. The triglyceride levels and plasma glucose levels at 0, 30, 60, 90 and 120 minute and the plasma insulin levels at 30, 60, 90 and 120 minutes after initiating the oral glucose tolerance test in women with PCOS were significantly higher compared to those values for the controls. The HOMA-IR was significantly higher in the women with PCOS compared to the controls, even after adjusting for age and the body mass index. CONCLUSIONS: Obesity and clinical hyperandrogenism were not frequent in Korean women with PCOS, but this population did display distinct insulin resistance.

This study was performed to evaluate the efficiency of simplified EM grid vitrification, skipping the step of removing the cryoprotectant (5.5M EG + 1.0M sucrose) droplet on the grid after loading oocytes, compared to conventional cryopreservation protocols for mouse mature oocytes. Firstly, the recovery, survival, fertilization and hatching rates of simplified EM grid vitrification were compared with those of the slow freezing method using 1.5M DMSO. Then, conventional EM grid vitrification was compared with simplified EM grid vitrification. Simplified EM grid vitrification showed higher survival, fertilization and hatching rates than those of the slow freezing method (85.6% vs. 63.2%; 51.0% vs. 22.3%; 38.7% vs. 12.5%, p < 0.01, respectively). Moreover, simplified EM grid vitrification showed higher recovery, survival and fertilization rates than those of conventional EM grid vitrification (100% vs. 95.0%, p=0.024; 90.0% vs. 78.9%, p=0.033; 56.7% vs. 38.7%, p=0.021, respectively). Hatching rate tended to be higher for simplified EM grid vitrification compared to conventional EM grid vitrification (41.1% vs. 24.1%). In conclusion, simplified EM grid vitrification is a convenient and efficient method for cryopreservation of mouse mature oocytes, compared to conventional EM grid vitrification and slow freezing methods.
