An herbal medicinal product consisting of three kinds of herbal materials, Prunella vulgaris L. (Lamiaceae), Clematis chinensis Osbeck (Ranunculaceae) and Trichosanthes kirilowii Max. (Cucurbitaceae) has been prescribed in the clinic for treating rheumatoid arthritis in Korea. In the present study, we investigated the antidepressive effect of this herbal complex extract (HCE) on lipopolysaccharide (LPS)-induced depression-like behavior. The effects of HCE on LPSinduced depressive-like behaviors were evaluated using a forced swimming test (FST) and splash test. In addition, we also evaluated locomotor activity and anxiety-like behaviors using the open field test and elevated plus-maze (EPM) test.Inflammatory cytokines were evaluated in the cortical regions. HCE attenuated anxiety-like behavior in the EPM test and depressive- and anhedonia-like behaviors induced by LPS in the FST and splash test. In addition, LPS-induced increases in the phosphorylation levels of protein kinase B (Akt) and glycogen synthase kinase 3 beta (GSK-3β) and expression levels of proinflammatory factors in the cortex were normalized by HCE. Moreover, decreases in the level of BDNF in the cortex were attenuated by HCE. These results suggest that HCE attenuates inflammation-induced depression-like behaviors through its normalization of Akt-GSK-3β signaling and proinflammatory factors and its upregulation of BDNF in the cortex and that HCE has therapeutic potential for depressive disorders in inflammatory states.

Purpose:
A near-infrared (NIR) fluorescence imaging is a promising tool for cancer-specific image guided surgery. Human epidermal receptor 2 (HER2) is one of the candidate markers for gastric cancer. In this study, we aimed to synthesize HER2-specific NIR fluorescence probes and evaluate their applicability in cancer-specific image-guided surgeries using an animal model.
Materials and Methods:
An NIR dye emitting light at 800 nm (IRDye800CW; Li-COR) was conjugated to trastuzumab and an HER2-specific affibody using a click mechanism. HER2 affinity was assessed using surface plasmon resonance. Gastric cancer cell lines (NCI-N87 and SNU-601) were subcutaneously implanted into female BALB/c nu (6–8 weeks old) mice.After intravenous injection of the probes, biodistribution and fluorescence signal intensity were measured using Lumina II (Perkin Elmer) and a laparoscopic NIR camera (InTheSmart).
Results:
Trastuzumab-IRDye800CW exhibited high affinity for HER2 (KD =2.093(3) pM).Fluorescence signals in the liver and spleen were the highest at 24 hours post injection, while the signal in HER2-positive tumor cells increased until 72 hours, as assessed using the Lumina II system. The signal corresponding to the tumor was visually identified and clearly differentiated from the liver after 72 hours using a laparoscopic NIR camera. AffibodyIRDye800CW also exhibited high affinity for HER2 (KD =4.71 nM); however, the signal was not identified in the tumor, probably owing to rapid renal clearance.
Conclusions
Trastuzumab-IRDye800CW may be used as a potential NIR probe that can be injected 2–3 days before surgery to obtain high HER2-specific signal and contrast. Affibodybased NIR probes may require modifications to enhance mobilization to the tumor site.

BACKGROUND: There has been no practical guidelines for the management of patients with central nervous system (CNS) tumors in Korea for many years. Thus, the Korean Society for Neuro-Oncology (KSNO), a multidisciplinary academic society, started to prepare guidelines for CNS tumors from February 2018. METHODS: The Working Group was composed of 35 multidisciplinary medical experts in Korea. References were identified through searches of PubMed, MEDLINE, EMBASE, and Cochrane CENTRAL using specific and sensitive keywords as well as combinations of keywords. RESULTS: First, the maximal safe resection if feasible is recommended. After the diagnosis of a glioblastoma with neurosurgical intervention, patients aged ≤70 years with good performance should be treated by concurrent chemoradiotherapy with temozolomide followed by adjuvant temozolomide chemotherapy (Stupp's protocol) or standard brain radiotherapy alone. However, those with poor performance should be treated by hypofractionated brain radiotherapy (preferred)±concurrent or adjuvant temozolomide, temozolomide alone (Level III), or supportive treatment. Alternatively, patients aged >70 years with good performance should be treated by hypofractionated brain radiotherapy+concurrent and adjuvant temozolomide or Stupp's protocol or hypofractionated brain radiotherapy alone, while those with poor performance should be treated by hypofractionated brain radiotherapy alone or temozolomide chemotherapy if the patient has methylated MGMT gene promoter (Level III), or supportive treatment. CONCLUSION: The KSNO's guideline recommends that glioblastomas should be treated by maximal safe resection, if feasible, followed by radiotherapy and/or chemotherapy according to the individual comprehensive condition of the patient.

BACKGROUND: There was no practical guideline for the management of patients with central nervous system tumor in Korea for many years. Thus, the Korean Society for Neuro-Oncology (KSNO), a multidisciplinary academic society, has developed the guideline for glioblastoma. Subsequently, the KSNO guideline for World Health Organization (WHO) grade II cerebral glioma in adults is established. METHODS: The Working Group was composed of 35 multidisciplinary medical experts in Korea. References were identified by searching PubMed, MEDLINE, EMBASE, and Cochrane CENTRAL databases using specific and sensitive keywords as well as combinations of keywords regarding diffuse astrocytoma and oligodendroglioma of brain in adults. RESULTS: Whenever radiological feature suggests lower grade glioma, the maximal safe resection if feasible is recommended globally. After molecular and histological examinations, patients with diffuse astrocytoma, isocitrate dehydrogenase (IDH)-wildtype without molecular feature of glioblastoma should be primarily treated by standard brain radiotherapy and adjuvant temozolomide chemotherapy (Level III) while those with molecular feature of glioblastoma should be treated following the protocol for glioblastomas. In terms of patients with diffuse astrocytoma, IDH-mutant and oligodendroglioma (IDH-mutant and 1p19q codeletion), standard brain radiotherapy and adjuvant PCV (procarbazine+lomustine+vincristine) combination chemotherapy should be considered primarily for the high-risk group while observation with regular follow up should be considered for the low-risk group. CONCLUSION: The KSNO's guideline recommends that WHO grade II gliomas should be treated by maximal safe resection, if feasible, followed by radiotherapy and/or chemotherapy according to molecular and histological features of tumors and clinical characteristics of patients.

BACKGROUND: There was no practical guideline for the management of patients with central nervous system tumor in Korea in the past. Thus, the Korean Society for Neuro-Oncology (KSNO), a multidisciplinary academic society, developed the guideline for glioblastoma successfully and published it in Brain Tumor Research and Treatment, the official journal of KSNO, in April 2019. Recently, the KSNO guideline for World Health Organization (WHO) grade III cerebral glioma in adults has been established. METHODS: The Working Group was composed of 35 multidisciplinary medical experts in Korea. References were identified by searches in PubMed, MEDLINE, EMBASE, and Cochrane CENTRAL databases using specific and sensitive keywords as well as combinations of keywords. Scope of the disease was confined to cerebral anaplastic astrocytoma and oligodendroglioma in adults. RESULTS: Whenever radiological feature suggests high grade glioma, maximal safe resection if feasible is globally recommended. After molecular and histological examinations, patients with anaplastic astrocytoma, isocitrate dehydrogenase (IDH)-mutant should be primary treated by standard brain radiotherapy and adjuvant temozolomide chemotherapy whereas those with anaplastic astrocytoma, NOS, and anaplastic astrocytoma, IDH-wildtype should be treated following the protocol for glioblastomas. In terms of anaplastic oligodendroglioma, IDH-mutant and 1p19q-codeletion, and anaplastic oligodendroglioma, NOS should be primary treated by standard brain radiotherapy and neoadjuvant or adjuvant PCV (procarbazine, lomustine, and vincristine) combination chemotherapy. CONCLUSION: The KSNO's guideline recommends that WHO grade III cerebral glioma of adults should be treated by maximal safe resection if feasible, followed by radiotherapy and/or chemotherapy according to molecular and histological features of tumors.

BACKGROUND: After initial radioactive iodine (RAI) treatment in differentiated thyroid cancer patients, we sometimes observe a star-shaped region of intense uptake of 131I on whole body scans (WBSs), called a ‘star artifact.’ We evaluated the clinical implications of star artifacts on the success rate of remnant ablation and long-term prognosis. METHODS: Total 636 patients who received 131I dose of 1.1 GBq for the initial RAI therapy and who did not show distant metastasis at the time of diagnosis were retrospectively evaluated. A negative second WBS was used for evaluating the ablation efficacy of the RAI therapy. Among them, 235 patients (36.9%) showed a star artifact on their first WBS. RESULTS: In patients with first stimulated thyroglobulin (sTg) levels ≤2 ng/mL, patients with star artifacts had a higher rate of negative second WBS compared with those without star artifacts (77.8% vs. 63.9%, P=0.044), and showed significantly higher recurrence-free survival (P=0.043) during the median 8.0 years (range, 1.0 to 10.0) of follow-up. The 5- and 10-year recurrence rates (5YRR, 10YRR) were also significantly lower in patients with star artifacts compared with those without (0% vs. 4.9%, respectively, P=0.006 for 5YRR; 0% vs. 6.4%, respectively, P=0.005 for 10YRR). However, ablation success rate or recurrence-free survival was not different among patients whose first sTg levels >2 ng/mL regardless of star artifacts. CONCLUSION: Therefore, star artifacts at initial RAI therapy imply a good ablation efficacy or a favorable long-term prognosis in patients with sTg levels ≤2 ng/mL.

Allergic rhinitis (AR) is one of the most common chronic allergic respiratory diseases worldwide. Various practical guidelines for AR have been developed and updated to improve the care of AR patients; however, up to 40% patients remain symptomatic. The unmet need for AR care is one of the greatest public health problems in the world. The gaps between guideline and real-world practice, and differences according to the region, culture, and medical environments may be the causes of unmet needs for AR care. Because there is no evidence-based AR practical guideline reflecting the Korean particularity, various needs are increasing. The purpose of the study was to evaluate whether existing guidelines are sufficient for AR patient management in real practice and whether development of regional guidelines to reflect regional differences is needed in Korea. A total of 99 primary physicians comprising internists, pediatricians, and otolaryngologists (n=33 for each) were surveyed by a questionnaire relating to unmet needs for AR care between June 2 and June 16 of 2014. Among 39 question items, participants strongly agreed on 15 items that existing guidelines were highly insufficient and needed new guidelines. However, there was some disagreement according to specialties for another 24 items. In conclusion, the survey results demonstrated that many physicians did not agree with the current AR guideline, and a new guideline reflecting Korean particularity was needed.

PURPOSE: The prevalence of allergic rhinitis is rapidly increasing and results in relatively high socio-economic burden on their family and community. However, studies on the economic burden of pediatric allergic rhinitis in Korea are limited. Therefore, we conducted this study to investigate the impact of pediatric allergic rhinitis on economic burden. METHODS: Two hundred sixty two children with allergic rhinitis were enrolled in 6 secondary or tertiary medical centers in Seoul from July to September, 2008. We collected data of the economic burden of allergic rhinitis (direct medical costs, direct nonmedical costs, and indirect costs) by face to face questionnaire survey. We compared the economic burden according to the severity and the duration of allergic rhinitis. RESULTS: The mean age of subjects was 6.54 years, and male were 174 (66.4%). Direct medical costs (10,000 Korean Won/yr) were 177.75, and direct nonmedical costs were 57.92. Although, there was no statistical significance, direct medical costs showed increasing trends in severe allergic rhinitis.(P=0.053) In addition, direct medical costs were positively correlated with duration of allergic rhinitis.(R=0.195, P=0.002). About 17% of the parents who care the allergic rhinitis children experienced the work absence due to their child's illness. CONCLUSION: The economic burdens of allergic rhinitis were positively correlated with the severity and duration of illness. Particularly costs for alternative medicine including oriental medicine were related with severity and duration allergic rhinitis. Therefore, special efforts for education with evidence based treatment strategy are necessary to decrease the economic burden of allergic rhinitis.

PURPOSE: Recent studies suggest that oral probiotic administration might be useful in the management of atopic dermatitis. Probiotics are known to promote the maturation of gut- associated lymphoid tissue (GALT) and control inflammatory responses. The purpose of this study was to evaluate clinical and anti-inflammatory effects on children's atopic dermatitis with Lactobacillus casei (L. casei), a kind of probiotic, supplementations. METHODS: Forty four patients with atopic dermatitis who visited the Pediatric Allergy Clinic in Soonchunhyang University Hospital from December 2004 to April 2005 were enrolled. We evaluated the SCORAD scores. Then, fresh stools were collected and cultured to count colony numbers of L. casei, and blood were samples were taken to measure IFN-gamma, total IgE, specific IgE (house dust mites, milk, egg white, dog hair, soy bean), peripheral blood eosinophil percent, and ECP. We divided patients by two groups randomly. L. casei containing yoghurt was ingested by one group but not by the other group for 16 weeks. After that period, SCORAD scores, stool cultures and blood samples were reevaluated. RESULTS: Most patients who received L. casei experienced improvement of atopic dermatitis, but changes in SCORAD scores were not so significant compared with the other group. Just forty patients had their blood tested again (L. casei group was 21), and there were no statistical significances. There were also no significant changes of specific IgE, eosinophil percent, ECP, total IgE, and IFN-gamma levels, before and after. The colony counts of L. casei in stool which were cultured after investigation, were relatively high in the group with L. casei supplements. (P=0.03) Conclusion: The administration of L. casei in children with atopic dermatitis might be helpful to improve the colony counts of L. casei in intestines, and these increased L. casei are expected to act as a down-regulator of allergic inflammation, but more investigations should be conducted to reveal the precise mechanisms and possible complications.
