The etiology of the cleft lip and palate can be explained with a multifarious theory. According to articles, there are some relationships between congenital toxoplasmosis and the cleft lip&palate, but the direct relationships is not obvious. Therefore, this research aims to find the difference of the serum toxoplasma antibody titer between 172 cleft patients who have been treated at National Medical Center and their mother group of 81 cases, healthy control group of 150 cases. The antibody titer was identified by the indirect fluorescent antibody test(>16)and the enzyme-linked immunosorbent assay(>0.3). The results are as follow : 1. By ELISA, the positive rate of the cleft patients(8.1%, 14cases)and that of the mother group(9.9%, 8cases)is higher than the healthy control group(2.7%, 4cases)(p<0.05). 2. By IFAT, the positive rate of the cleft patients(10.5%, 18cases)is higher than the healthy control group(5.3%, 8cases), but the difference is not significant(p>0.05). And the positive rate of the mother group(13.6%, 11cases)is higher than the healthy control group(5.3%, 8cases)(p<0.05). 3. By ELISA and IFAT, the positive rate of the mother group is higher than the cleft patient but the difference is not significant. 4. By ELISA and IFAT, the positive rate of the cleft patients according to the clincal group is not significant. 5. By ELISA and IFAT, the positive rate of the chronic disease group(17.3% & 27.7%)is higher than the healthy control group(2.7% & 5.3%)(p<0.05).

Background/Aims: The overall age-matched incidence of gastroduodenal ulcers was considerably higher in cirrhotic patients compared to the general population. There are several possible underlying mechanisms which may explain the ulcerogenic factors in cirrhotic patients. Recently, Helicobacter pylori (H. pylori) was proven as the cause of peptic ulcer disease in the general population. But the role of H. pylori infection in the pathogenesis of peptic ulcers of cirrhotic patients has not been clearly elucidated. The purpose of this study was to determine the role of H. pylori infection in cirrhotic patients with peptic ulcers. Methods: From 1995 to 1997, 105 patients with histologically or radiologically proven liver cirrhosis (LC) who received panendoscopic examination due to presence of any upper gastrointestinal symptoms were studied. During endoscopic examination, a CLO (campylobacter like organism) test or gastric antral mucosal biopsy was performed in all patients. The severity of LC assessed by Child's criteria revealed that 31 patients had Child's A, 26 patients Child's B, and the remain 48 patients, Child's C. Child B or C was classified as decompensated LC. An esophageal varix was present in 73 patients or absent in 32. Results: There was no statistical difference in the H. pylori prevalance between the ulcer group and non-ulcer group (67% vs 52%). In Child A group, the H. pylori prevalence was significantly higher in the ulcer group when compared with the non-ulcer group (87% vs 50%, p<0.05). In contrast, in the Child B or C group, there was no statistical difference between the ulcer group and non-ulcer group. In the abscence of esophageal varix, the ulcer group showed significantly higher prevalence of H. pylori than the non-ulcer group (87% vs 59%, p<0.05). But in the esophageal variceal group, there was no significant difference in the H. pylori prevalence between the ulcer and non-ulcer group (60% vs 40%). Conclusions: These observations suggest that H. pylori infection may play a role in the phogenesis of peptic ulcer in compensated cirrhotic patients. However, in cirrhotic patients with decompensation or an esophageal varix, the association between H. pylori infection and peptic ulcers was weak, so other factors (portal hypertension etc.) should be considered as more potent etiology of peptic ulcers in cases of decompensated cirrhosis.

肝吸蟲症의 化學豫防에 關한 硏究 : 第 3 報 Hexachlorophen 및 1,4-Bis-trichloromethylbenzol (Hetol)의 肝吸蟲感染 初期에 있어서의 殺幼蟲效果 Report 3. The larvicidal effects of Hexachlorophene and 1, 4-Bis-trichloromethylbenzol (Hetol) in the early stage of Clonorchis sinensis infection

In this study, using 26 experimental rabbits, proper doses of Hexachlorophene or 1,4-Bis-trichloromethylbenzol ere administered to the rabbits from 1st day of the infection with 500 metacercariae of Clonorchis sinensis. The larvicidal effects of the drugs were judged by the results of examination of Clonorchis eggs in feces and detection status of the adult worms from the liver at autopsy. And the following results were obtained. 1) In the control group, the detection rate of adult worm was 42.4%. 2) In the group of 10 times administration of Hexachlorophene 40mg(20mg/kg dody weight) in every day dose from 1st day of Clonorchis infection, there was no good larvicidal effect observed and the detection rate of adult worm was 19.0%. 3) In the group of 1,4-Bis-trichloromethylbenzol administration from 1st day of Clonorchis infection, there were no obvious larvicidal effects observed, and the detection rates of adult worm were 46.6%, 29.6% and 43.8% respectively in each of 10 times administration of the drug 100mg(50mg/kg body weight) in every day dose, 5 time administration of the drug 200mg(100mg/kg) in every day dose and 3 times administration of the drug 600mg(300mg/kg) in every other day dose.

Jeong, Hyun-Ja,Na, Ho-Jeong,Kim, Su-Jin,Rim, Hong-Kun,Myung, Noh-Yil,Moon, Phil-Dong,Han, Na-Ra,Seo, Jae-Uk,Kang, Tae-Hee,Kim, Jae-Joong,Choi, Youngjin,Kang, In-Cheol,Hong, Seung-Heon,Kim, You-Ah,Seo, Pharmaceutical Society of Japan 2009 BIOLOGICAL & PHARMACEUTICAL BULLETIN Vol.32 No.6

<P>In the present study, we extracted <I>Corydalis heterocarpa</I> with various solvents in order to find the bioactive constituents that demonstrated anti-inflammatory effects. We isolated the active compound, Columbianetin. Anti-inflammatory effect of Columbianetin has been reported but the precise effects of Columbianetin in experimental models have remained unknown. In the present study, we investigate the effect of Columbianetin on the production of histamine, interleukin (IL)-1β, IL-6, IL-8, and tumor necrosis factor (TNF)-α and expression of cyclooxygenase-2 (COX-2) by using the human mast cell line (HMC-1). Various concentrations of Columbianetin were treated before the activation of HMC-1 cells with phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore, A23187. PMA plus A23187 significantly increased IL-1β, IL-6, IL-8, and TNF-α production compared with media control (<I>p</I><0.05). We also show that the increased cytokines IL-1β, IL-6, IL-8, and TNF-α level was significantly inhibited by Columbianetin in a dose-dependent manner (<I>p</I><0.05). Maximal inhibition rates of IL-1β, IL-6, IL-8, and TNF-α production by Columbianetin were about 102.6%, 101.1%, 95.8%, and 103.9%, respectively. Columbianetin inhibited expression of COX-2. In addition, the effect of Columbianetin was investigated on the histamine release from HMC-1 stimulated by substance P, which promotes histamine release. Columbianetin also inhibited the histamine release by substance P. In conclusion, these results indicate that Columbianetin may be helpful in regulating mast cell-mediated allergic inflammatory responses.</P>

Purpose: The first Korean national population- based cancer registry using nationwide hospital-based recording system and the regional cancer registries provided the source to obtain national cancer incidences for the period 1999∼2001.Materials and Methods: The incidence of cancer in Korea was calculated based on the Korea Central Cancer Registry database, data from additional medical record review survey, the Regional Cancer Registry databases, site-specific cancer registry databases, and cancer mortality data from the Korea National Statistical Office. Crude and age-standardized rates were calculated by sex for 18 age groups.Results: The overall crude incidence rates (CR) were 247.3 and 188.3 per 100,000 for men and women and the overall age-standardized incidence rates (ASR) were281.2 and 160.3 per 100,000, respectively. Among men, five leading primary cancer sites werestomach (CR 58.6, ASR 65.6), lung (CR 42.1, ASR 50.9), liver (CR 41.9, ASR44.9), colon and rectum (CR 24.2, ASR 27.3) and bladder (CR 7.7, ASR 9.2). Among women, the most common cancers were stomach (CR 30.8, ASR 25.8), breast (CR25.7, ASR 21.7), colon and rectum (CR 19.6, ASR 16.7), uterine cervix (CR 18.4, ASR 15.5), and lung cancer (CR 15.1, ASR 12.4). In 0∼14 age group, leukemia was mostcommon for both sexes. For men, stomach cancer was most common in 15∼64 age group, but lung cancer was more frequent for over 65 age group. For women, thyroidcancer in 15∼34 age group, breast cancer in 35∼64 age group, and stomach cancer in over 65 age group were most common for each age group. The proportions ofdeath certificate only were 7.5% for men and 7.4% for women.Conclusion: This is the first attempt to determine the national cancer incidence and this data will be useful to plan for research and national cancer control in Korea.

Seung-Rim Han,Chul Seung Lee,Jung Hoon Bae,Hyo Jin Lee,Mi Ran Yoon,Do Sang Lee,Yoon Suk Lee,Abdullah Al-Sawat,Jung-Woo Shim,Sang-Hyun Hong,In Kyu Lee 대한외과학회 2021 Annals of Surgical Treatment and Research(ASRT) Vol.101 No.4

Purpose: Intrathecal analgesia (ITA) and transverse abdominis plane block (TAPB) are effective pain control methods in abdominal surgery. However, there is still no gold standard for postoperative pain control in minimally invasive colorectal surgery. This study aimed to investigate whether the analgesic effect could be increased when TAPB, which can further reduce wound somatic pain, was administered in low-dose morphine ITA patients. Methods: Patients undergoing elective colorectal surgery were randomized into an ITA with TAPB group or an ITA group. Patients were evaluated for pain 0, 8, 16, 24, and 48 hours after surgery. The primary outcome was the total morphine milligram equivalents administered 24 hours after surgery. The secondary outcomes were pain scores, ambulatory variables, inflammation markers, hospital stay duration, and complications within 48 hours after surgery. Results: A total of 64 patients were recruited, and 55 were compared. There was no significant difference in morphine use over the 24 hours after surgery in the 2 groups (ITA with TAPB, 15.3 mg vs. ITA, 10.2 mg; P = 0.270). Also, there was no significant difference in pain scores. In both groups, the average pain score at 24 and 48 hours was 2 points or less, showing effective pain control. Conclusion: ITA for pain control in patients with colorectal surgery is an effective pain method, and additional TAPB was not effective.

본 연구에서는 충북대학교 조류질병학실험실에 2009년 한 해동안 의뢰된 산란계의 혈청 검사 결과에 대해 분석하여, 산란계의 주요 질병에 대한 국내 산란계의 면역 상태 및 질병 감염 실태를 파악하였다. 검사 대상 질병은 AI, ND, IB, aMPV, EDS'76, IBD, CIA이었으며, 산란계의 성장 단계에 따라 주령 구간을 나누어 분석하였다. AI, ND, IB는 모체이행항체가 감소한 후 산란 기간에 걸쳐 혈청 역가가 안정적으로 형성되는 특징을 보여 주었다. 그러나 AI는 모든 주령 구간에 걸쳐 음성인 계군이 존재하는 반면, ND는 3~10주령 구간의 한 음성 계군을 제외하고 전 주령에 걸쳐 100%의 계군 양성률을 보이고, ND의 평균 GMT가 AI의 평균 GMT보다 높았는데, 이는 두 질병의 백신 정책의 차이에 기인한 것이다. IB의 산란기의 안정적인 역가는 백신 역가에 산란기 전반에 걸친 야외 감염 개체의 존재로 인한 야외감염 역가가 더해진 것으로 판단된다. aMPV는 2009년에 백신을 실시하지 않았던 질병이므로, 양성 역가를 통해 aMPV의 야외 감염을 추적할 수 있었으며, GMT 변화 및 계군 내양성 개체율의 증가 경향을 통해 일령이 증가할수록 야외감염률이 증가하는 양상을 파악할 수 있었다. EDS'76은 산란 기간에 걸쳐 높은 양성률과 낮은 변이계수를 보여 야외감염이 아닌 백신에 의한 역가 형성이 대부분임을 알 수 있었다. IBD의 모체이행항체는 높은 수준으로 이행되는 것을 확인하였으며, CIA는 백신을 적용하지 않은 계군에서 양성과 음성 계군이 모두 존재하였으며, 그 차이는 차단 방역에 기인하는 것으로 판단되었다. 본 연구를 통하여 국내 산란계에서의 혈청 역가 분포를 파악하는데 많은 정보를 얻을 수 있었으나, 향후 지속적인 야외 계군의 혈청학적 모니터링이 되어야 할 것으로 판단된다. Serological evaluation for the poultry is important for various reasons, such as designing and assessing the vaccination program and diagnosing diseases and for this reason, serologic tests for the layer flocks have been conducted on a regular basis. Moreover, the nationwide serological survey and analysis are essential to understand the epidemiological status of national poultry industry. In this sense, the study was conducted to evaluate the immune status of the layer flocks with the sera submitted to Avian Disease Laboratory, Chungbuk National University in 2009, and several important viral diseases were selected for evaluation including low pathogenic avian influenza (LPAI), Newcastle disease (ND), infectious bronchitis (IB) and avian metapneumovirus (aMPV). For LPAI and ND, the age-related patterns of geometric mean titer (GMT) changes were similar but there were differences in the flock positive rate and the level of GMT due to the different vaccination policy. In the case of IB, the values of GMT showed that the field infection was more prevalent than expected. For aMPV, positive birds in a flock increased as the layers got older, which reflected the course of field infection because vaccination against aMPV was not allowed in 2009. From this study, the immune status for the main viral diseases in layers became more clarified but this information was limited because of only one year study. Therefore, serological survey needs to be conducted on a yearly basis and furthermore include broilers and breeders for a better understanding of the health status in the national poultry industry.

The cutaneous synthesis of vitamin D in response to ultraviolet radiation exposure is the most important factor in maintaining vitamin D balance in Man. The skin is not only the site of vitamin D synthesis, but also a target organ for calcitriol(1, 25-dihydroxy-vitamin D) which is naturally occuriag, hormonally active form of vitamin E. It is now known that calcitriol inhibits the proliferation of epidermal cells and induces her differentiation. In this study, epidermal keratinocytes and melanocytes were isilated from the neonatal foreskin, and were culturod using a MCDB 153 and modified TIC media, respectively. And then various concentratioris of calcipotriol(MC 903), a synthetic aralogue of calcitriol, were added to each culture. The effects of calcipotriol on the growth of human keratinocytes and melanocytes were investigated. The results were as follows : 1. The addition of calopotriol to human keratinocyte and melalocyte cultures inhibited their proliferation in a dosdependent manner. 2. Calcipotriol had no effects on the melanization process of the melanocyte. 3. Calcipotriol was found to inhibit the proliferation, however it induced the terminal differentiation of cultured keratinocytes, as judged by morphologicai changes. The decreased density of kerationcytes, The formation of cornified cells, and the cellular destruction in a concentration of 10 M of calcipotriol were observed. 4. By using the light atid the electron microscope, we observed that the epidermal thickness was decreased and terminal differentiation was facilitateir. Living Skin Equivalent (LSE) according to the increasing concentration of calcipotriol. A]i)parent cytotoxic effects were observed in 10 M, 10 M of calcipotriol. In summary, the above results indicate that the addition of calcipotriol to the in vitro culture system of human keratinocyte and melanocyte induces the biologic process of terminal differentiation of keratinocytes and inhibits proliferation of keratinoytes and melanocytes in a dose-dependent manner.

Kim, Su-Jin,Lee, Gi-Tak,Lee, Bo-Ra,Jeon, Kwon-Su,Rim, Hong-Kun,Bang, Jun-Ho,Kim, Yang-Gwi,Myung, No-Yil,Moon, Phil-Dong,Kim, Na-Hyung,Choi, In-Young,Choi, Young-Jin,Kang, In-Cheol,Um, Jae-Young,Hong, Kyung Hee Oriental Medicine Research Center 2009 Oriental pharmacy and experimental medicine Vol.9 No.2

Eriocaulon sieboldianum (ES) is used in traditional oriental medicine for various medicinal purposes including headache, toothache, and inflammation. However, the anti-cancer effect of the ES is still not fully understood. In the present study, the human leukemia cell line HL-60 was used to characterize the apoptotic effects of ES. ES induced cytotoxicity of HL-60 cells in a dose- and time-dependent manner. ES induced the generation of reactive oxygen species, and the release of cytochrome c in a dose-dependent manner. In addition, we showed that ES-induced apoptosis was accompanied by activation of caspase-3. Taken together, our results demonstrate that ES possesses anti-cancer activity in HL-60 cells.
