Infection-induced acute hepatitis complicated with acute pancreatitis is associated with hepatitis A virus, hepatitis B virus or hepatitis E virus. Although rare, Epstein-Barr virus (EBV) infection should be considered also in the differential diagnosis if the patient has acute hepatitis combined with pancreatitis. We report a case of EBV infection with cholestatic hepatitis and pancreatitis with review of literature. An 11-year-old female was admitted due to 1-day history of abdominal pain and vomiting without any clinical symptoms of infectious mononucleosis. Diagnosis of reactivated EBV infection was made by the positive result of viral capsid antigen (VCA) IgM, VCA IgG, Epstein-Barr nuclear antigen and heterophile antibody test. We performed serologic tests and magnetic resonance cholangiopancreatography to exclude other viral or bacterial infection, autoimmune disorder, and structural problems. The patient's symptoms recovered rapidly and blood chemistry returned to normal with conservative treatment similar to previously reported cases.

The effectiveness of three kinds of enzymes (chitinase, beta-glucuronidase, and lysing enzyme complex), employed as elicitors to enhance the beta-glucan content in the sawdust-based cultivation of cauliflower mushroom (Sparassis latifolia), was examined. The elicitors were applied to the cauliflower mushroom after primordium formation, by spraying the enzyme solutions at three different levels on the sawdust-based medium. Mycelial growth was fully accomplished by the treatments, but the metabolic process during the growth of fruiting bodies was affected. The application of a lysing enzyme resulted in an increase in the beta-glucan concentration by up to 31% compared to that of the control. However, the treatment resulted in a decrease in mushroom yield, which necessitated the need to evaluate its economic efficiency. Although we still need to develop a more efficient way for using elicitors to enhance functional metabolites in mushroom cultivation, the results indicate that the elicitation technique can be applied in the cultivation of medicinal/edible mushrooms.

3.Spore Dispersion of Tricholoma matsutake at a Pinus densiflora Stand in Korea.
Mycobiology 2010;38(3):203-205
The spore of Tricholoma matsutake is considered to be the starting point of the mushroom growth cycle, but the mechanism of mycelial development from the spore stage is not yet clarified. In this study, we tried to measure how far the spores of T. matsutake disperse from a fruiting body located at a Pinus densiflora stand in Korea. We established 16 slide glasses coated with glycerin near a fruiting body in four directions separated by four different distance intervals within a mushroom productive stand after removing all other fruiting bodies from three plots. The number of dispersed spores increased with time from the first day (475 spores/cm2) to the fourth day (836 spores/cm2) after the pileus opened. The number of spores dispersed downward was about 1.5 times greater than that dispersed toward the ridge. The number of dispersed spores decreased exponentially as the distance from each fruiting body increased. More than 95% of the spores dropped within a meter from the fruiting body, with 75% dropping within 0.5 m. Even so, the number of spores dispersed over 5 m from the fruiting body was more than 50 million when considering the total number of spores produced by a fruiting body is about 5 billion.

OBJECTIVES: The aim of this study was to compare differences in perception and knowledge of child abuse and child disciplinary practices according to the history of child abuse victimization. METHODS: A questionnaire survey on child abuse was conducted with 491 adults raising children. We compared the perception and knowledge of child abuse and child disciplinary practices between two groups of adults with and without a history of childhood abuse victimization. RESULTS: The group with a history of childhood abuse had lower levels of knowledge of child abuse (F=6.990, p<0.01) and engaged in more negative disciplinary practices (F=5.974, p<0.05) than those without. However, no differences in the perception of child abuse were observed between the two groups. CONCLUSION: The results suggest that adults with a history of childhood abuse have lower levels of knowledge of child abuse and use more negative disciplinary practices in raising their children. This highlights the need to administer not only educational but also more direct hands-on interventions to vulnerable parents in order to foster healthy parenting and disciplinary practices.

PURPOSE: To identify the brain centers associated with visually evoked sexual arousal in the human brain, and to investigate the neural mechanism for sexual arousal using functional MRI (fMRI). MATERIALS AND METHODS: A total of 20 sexually potent volunteers consisting of 10 males (mean age: 24) and 10 females (mean age: 23) underwent fMRI on a 1.5 T MR scanner (GE Signa Horizon). The fMRI data were obtained from 7 slices (10 mm slice thickness) parallel to the AC-PC (anterior commissure and posterior commissure) line, giving a total of 511 MR images. The sexual stimulation consisted of a 1-minute rest with black screen, followed by a 4-minute stimulation by an erotic video film, and concluded with a 2-minute rest. The brain activation maps and their quantification were analyzed by the statistical parametric mapping (SPM 99) program. RESULTS: The brain activation regions associated with visual sexual arousal in the limbic system are the posterior cingulate gyrus, parahippocampal gyrus, hypothalamus, medial cingulate gyrus, thalamus, amygdala, anterior cingulate gyrus, insula, hippocampus, caudate nucleus, globus pallidus and putamen. Especially, the parahippocampal gyrus, cingulate gyrus, thalamus and hypothalamus were highly activated in comparison with other areas. The overall activities of the limbic lobe, diencephalon, and basal ganglia were 11.8%, 10.5%, and 3.4%, respectively. In the correlation test between brain activity and sexual arousal, the hypothalamus and thalamus showed positive correlation, but the other brain areas showed no correlation. CONCLUSION: The fMRI is useful to quantitatively evaluate the cerebral activation associated with visually evoked, sexual arousal in the human brain. This result may be helpful by providing clinically valuable information on sexual disorder in humans as well as by increasing the understanding of the neuroanatomical correlates of sexual arousal.

Extracellular amylase properties were examined with the mycelium of Tricholoma matsutake isolated from ectomycorrhizal roots of Pinus densiflora. The molecular weights of alpha-amylase and glucoamylase were estimated as 34.2 kD and 11.5 kD, respectively, after eluted through Superdex 75 column. The optimum pH of the purified enzyme was found in a range of pH 5.0~6.0, with a peak at pH 5.0. The activities of these enzymes were stable from 4degrees C to 30degrees C. The alpha-amylase of T. matsutake readily hydrolyzed soluble starch and amylose-B, while it weakly hydrolyzed glycogen, dextrin, amylose and amylose-A. The main products of hydrolysis were confirmed to be glucose, maltose and maltotriose on the basis of the similarities in the thin layer chromatographic mobility.

Trichoderma spp. cause large crop losses of the cultivated shiitake mushroom, Lentinula edodes. We bred several shiitake strains that are resistant to Trichoderma spp. using di-mon mating to establish a useful method for controlling the greenmold disease. We examined the competitive ability of L. edodes against Trichoderma spp. using a dual culture system to select resistant strains. By screening Trichoderma-resistant strains, we found that among 11 parental strains, 4 strains, including KFRI 36, were confirmed resistant strains. They showed especially strong resistance to T. harzianum, which formed deadlock after mycelial contact and then invaded into the territory of T. harzianum. KFRI 171 also showed resistance to T. atroviride strains. Among 13 strains, which were made by hybridization of shiitake strains, 5 were confirmed to be resistant to Trichoderma, including KFRI 58-1. Their resistance was not correlated to the resistant activity of their parents' strains. Two strains lose resistance and two strains acquire resistance compared to their parents' strains. In SEM observation, the mycelium of L. edodes at the interaction zone of Lentinula-Trichoderma was rugged and swollen by T. harzianum.

PURPOSE: The purpose of the study was to develop and evaluate the effect of a metabolic syndrome prevention program using mobile application for university students. METHODS: A pretest-posttest design with content analysis as a triangulation method was used. The participants were 49 university students. Data were analyzed using descriptive statistics, chi2-test, t-test and Fisher's exact test with the SPSS WIN 18.0 program. RESULTS: The application consisted of six main menus as follows: 'basic education', 'nutrition education', 'exercise education', 'meal diary', 'exercise checkup', and 'tips'. The experimental group had higher recognition about metabolic syndrome prevention than the control group (F=7.919, p=.007). Understanding of metabolic syndrome among participants was mostly related to chronic diseases such as obesity, hypertension and diabetes in relation to the importance of eating habits and exercising. CONCLUSION: The results indicate that metabolic syndrome prevention education using mobile application is necessary and would be useful for university students.

OBJECTIVES: The aim of this cross-sectional study was to compare the subjective quality of life in the four groups of antipsychotics according to the risk of weight gain in patients with schizophrenia. METHODS: One hundred and thirty-two patients with schizophrenia that had taken the same antipsychotics for more than 1 year were enrolled in the analyses. Anti-psychotic agents were classified by the risk of weight gain into four groups : serious, common, not unusual, and unusual. The quality of life was measured with the Schizophrenia Quality of Life Scale Korean version, 4th Revision (SQLS-R4K). We analyzed the correlation between the total score of SQLS-R4K and clinical variables. RESULTS: The SQLS-R4K score was significantly different in the four anti-psychotic groups (F=5.200, p=0.002). Gender, type of anti-psychotics (typical, atypical), duration of treatment with current antipsychotics, duration of illness, and Body Mass Index were not significantly correlated with the SQLS-R4K score. CONCLUSION: The subjective quality of life was different according to the risk of weight gain groups of anti-psychotic agents.

Visceral larva migrans (VLM) syndrome is a clinical manifestation of systemic organ involvement by Toxocara species. VLM with involvement of the bladder and liver is a rare finding. A 62-year-old woman presented with diffuse bladder wall thickening and multiple liver masses with peripheral eosinophilia and urinary symptoms. We considered malignancy or eosinophilic cystitis through clinical manifestations and imaging findings. However, no suspicious malignant lesions were observed on cystoscopy and liver mass biopsy revealed the presence of eosinophilic necrotizing granuloma without malignant cells. Anti-Toxocara antibodies were detected by western blotting and the patient was diagnosed with VLM syndrome. After taking prednisolone, urinary symptoms disappeared. On abdominal CT scan taken after three months, the size of multiple liver masses and bladder wall thickening had decreased. VLM syndrome should be suspected in patients with an atypical imaging pattern and peripheral eosinophilia.
