  • Our work in this study was made in the microsomal fraction to evaluate the lipid peroxidation by measuring superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and malondialdehyde (MDA) and to elucidate the preventive role of CS in the $CCl_4$-induced oxidative stress. The excessive lipid peroxidation by free radicals derived from $CCl_4$ leads to the condition of oxidative stress which results in the accumulation of MDA. MDA is one of the end-products in the lipid peroxidation process and oxidative stress. MDA, lipid peroxide, produced in this oxidative stress causes various diseases related to aging and hepatotoxicity, etc. Normal cells have a number of enzymatic and nonenzymatic endogenous defense systems to protect themselves from reactive species. The enzymes in the defense systems, for example, are SOD, CAT, and GPx. They quickly eliminate reactive oxygen species (ROS) such as superoxide anion free radicalㆍO$^{[-10]}$ $_2$, hydrogen peroxide $H_2O$$_2$ and hydroxyl free radicalㆍOH. CS inhibited the accumulation of MDA and the deactivation of SOD, CAT and GPx in the dose-dependent and preventive manner. Our study suggests that CS might be a potential scavenger of free radicals in the oxidative stress originated from the lipid peroxidation of the liver cells of $CCl_4$-treated rats.

  • Purpose: This study was performed to evaluate anti-inflammatory effects of Jogantanggagambang(JGTG). Methods: In the study of anti-oxidant activities, JGTG was investigated by DPPH radical scavenger activity, superoxide dismutase activity and superoxide anion radical scavenger activity. In the study of anti-inflammatory effects, JGTG was investigated using cultured cells and murine models. As for the parameters of inflammation, levels of several inflammatory cytokines and chemical mediators which are known to be related to inflammation were measured in mouse lung fibroblast cells(mLFCs) and RAW264.7 cells. Results: 1. JGTG showed a safety in cytotoxicity and toxicity of liver. 2. JGTG effected scavenging activity on DPPH free radical, superoxide dismutase and superoxide anion radical. 3. JGTG in RAW 264.7 cell decreased IL-$1{\beta}$ mRNA expression, IL-6 mRNA expression, TNF-${\alpha}$ mRNA expression at 50, $100{\mu}g/m{\ell}$ and also decreased NOS-II mRNA expression at $100{\mu}g/m{\ell}$, and decreased COX-2 mRNA expression at 10, 50, $100{\mu}g/m{\ell}$. 4. JGTG in RAW 264.7 cell decreased significantly IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ at 50, $100{\mu}g/m{\ell}$. 5. JGTG inhibited significantly IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ production in serum of acute inflammation-induced mice. 6. JGTG decreased significantly IL-$1{\beta}$ mRNA production in spleen tissue. Conclusion: These results suggest that JGTG can be used for treating diverse female diseases caused by inflammation

  • This study aims to furnish basic data about prevention and infection control of Hepatitis B Virus(HBV) for those who, working in dental offices, are particularly exposed to a high risk of HBV infection. A survey was conducted to 310 students including freshmen, sophomores and juniors enrolled in the dental hygiene department in order to examine their knowledge about infection routes of HBV, clinical history of their family members and their own health. The outcomes of the survey showed following facts; 1. Students were found to lack knowledge about the present conditions of their HBsAg and HBsAb of HBV(PF0.05), conduct of preventive vaccination(PE0.05), completion of 3 required vaccinations(PF0.05) and formation of antibody(PF0.05). 2. Students named "blood"(88.6%) and "infected needles"(82.5%) as most likely infection routes of HBV(PE0.05 and PE0.01). These replies came mostly from sophomores(65.6% and 92.1%), followed by juniors(89.2%, 82.5%) and freshmen(81.1%, 73.0%). Least knowledge about infection routes of HBV was sensed with the reply "infection through breast-feeding of positive mother(27.9%)"(PE0.05). Generally, sophomores seemed to have much knowledge about infection routes, followed by juniors and freshmen in order. 3. As to clinical history of family members, 10 students(3.5%) replied that any of their family members is suffering from HBV now, 8(2.6%) revealed that some of their family members once suffered from it and 10(3.2%) reported cases of death of their family members from liver diseases. 4. Ninety-four point seven percent of respondents believed their health to be better than normal.

  • Objectives: With the aging of the population, the incidence of a variety of diseases is increasing. Cerebrovascular disease is a major cause of mortality worldwide and therefore requires timely treatment and management. We aimed to evaluate the clinical effectiveness of herbal medicines in treating cerebrovascular disease by screening the most frequently prescribed herbal medicines and analyzing the clinical data of patients with cerebrovascular disease taking these medicines. Methods: In this retrospective study, we analyzed the electronic medical records of patients with cerebrovascular disease who received herbal medication at the Pusan National University Korean Medical Hospital from 10 March 2010 to 31 March 2017. The inclusion criteria were as follows: diagnosis of cerebrovascular disease, use of frequently prescribed herbal medicines, available records of laboratory tests and functional evaluation that was conducted within two weeks before and after admission and discharge, and herbal medicine usage exceeding half the period of hospitalization. Results: Of the total patients with cerebrovascular disease, the number of patients analyzed in this study was 49. There were some changes in the various variables examined after frequently used herbal medicines had been taken, such as complete blood count, liver function test, lipid test, and functional evaluation. No serious adverse events related to herbal medicine were found in this study. Conclusions: We concluded that herbal medicines frequently used for cerebrovascular disease may have some clinical effectiveness. However, because of the retrospective nature of this study and only one hospital involved, the generalizability of our findings is limited.

  • Obtaining an available information on health concerns of parents of school-age children and furthermore developing the sound policy for the public on health education, this study was conducted during Nov.-Dec. 1985 in the four selected areas; Seoul, large, middle and small city, and farming and fishery villages for 3,337 parents of schoolchildren in Korea. In this study, parents complected a questionnaire containing 34 items related to health concerns(e.g. drinking alcohol, air pollution, cancer, etc. see Table 4 and Fig. 2). For each health items, respondents were asked to indicate a choice between three levels of concern; 'Very high concern,' 'Moderate concern,' 'Little concern', and 'No opinion'. An analysis of responses indicated that most of the top ten health concerns identified by parents as cancer, abortions among high school students, medical malpractice, water pollution, traffic accidents, air pollution, suicide of parents and homicide of offspring, heart disease, venereal diseases, and high blood pressure in that order. Those health problems about which respondents were least concerned were more closely related to the individual, such as drinking alcohol, smoking, tooth decay, gum disease, underweight, overweight. Of greater concern were more such as water pollution, abortions among high school students, air pollution, accidents, medical malpractice. For cancer, heart disease, high blood pressure, various accidents, environmental pollution, parents showed high concern, however, for health issues which contributed as causative influences such as lung cancer from smoking and liver cirrhosis and traffic accidents from drinking alcohol showed less concern. Relationship between parent's residential areas, educational level and sex distribution and health concern showed little difference, however, for these issues parents identified as relatively high concern. Most parents stowed more concern in sex-related of family-related health issues such as abortions among high school students, suicide of parents and homicide of offspring.

  • A grower broiler experiment (from 14 to 35 days of age) was conducted to study the effect of using two commercial mixtures of organic acids (Galliacid$^{(R)}$ and Biacid$^{(R)}$) to substitute antibiotic growth promoter (Eneramycin$^{(R)}$) on performance, carcass characteristics and intestinal microflora. 400 (Ross 308) broiler chicks were used. A basal corn-soybean meal diet were formulated and served as a control treatment. The control diet was supplemented with either 0.06% Galliacid, 0.1% Biacid or 0.02% Eneramycin. Birds fed the Galliacid-supplemented diet had 16% (p<0.001) more gain than the control, while those fed the Biacid- or Enramycinsupplemented diets recorded 3 and 5.5% more gain, respectively. Organic acids mixtures and Enramycin supplementation significantly (p<0.001) improved feed conversion ratio. These results indicated that birds fed either organic acid mixtures or Enramycinsupplemented diets utilized feed more efficiently than those fed the control diet. Galliacid significantly (p<0.01) increased dressing percentage and bursa weight (% body weight). No significant differences were detected on liver, spleen and thymus (% body weight) among treatments. Galliacid or Biacid significantly (p<0.001) decreased intestinal Escherichia coli and Salmonella compared to the control and Enramycin-supplemented diets. Dietary Enramycin significantly (p<0.001) decreased Escherichia coli, but had no effect on Salmonella counts. In conclusion, organic acid mixtures are more efficient than antibiotic growth promoter (Enramycin) in improving broiler performance and decreasing intestinal Escherichia coli and Salmonella spp., and could be successfully used to substitute antibiotic growth promoters in broiler diets. However, not all of the organic acid mixtures gave the same effect either on performance or intestinal bacterial counts.

  • Background: Dermatoscopy can be applied to diagnose pigmented skin lesions. The aim of the present study was to compare dermatoscopic and histopathologic results in basal cell carcinoma (BCC) and melanocytic nevus of theface. Materials and Methods: In an analytical-descriptive study, 61 patients suspected of BCC or melanocytic nevi of face were randomly selected. The skin lesions of patients were evaluated with dermatoscopic method from February 2012 to February 2014 and results were compared with pathological features of samples. Results: In this study, mean age of patients was $49.5{\pm}18.9$. Some 25 (41%) were men and 36 (59%) were women. In 27 cases (44.3%) there was diagnosis of melanocytic nevus, in 28 cases (45.9%) diagnosis of BCC, and in 3 cases (4.9%) there was mixed diagnosis. The relationship between patients' gender and dermatoscopic diagnosis of the patients was statistically significant (P=0.001). For BCC the sensitivity and specificity of dermatoscopic method were 100% and 97% respectively and for melanocytic nevi 96.4% and 97%. Conclusions: Dermatoscopic study not only can be helpful in improving clinical diagnosis while guiding missed malignant lesions to pathologic evaluations, but also could be useful in evaluating further suspicious or recurrent cases.

  • Background: Survival rates after resection of advanced gastric cancer are extremely poor. An increasing number of patients with gastric carcinomas (GC) are therefore being treated with preoperative chemotherapy. We evaluated 36 month survival rate of GC patients that were treated by adding a neoadjuvant chemoradiotherapy before gastrostomy.Materials and Methods: Patients with stage II or III gastric adenocarcinomas were enrolled. The patients divided into two groups: (A) Neoadjuvant group that received concurrent chemoradiation before surgery (4500cGy of radiation at 180cGy per day plus chemotherapy with cisplatin and 5-fluorouracil, in the first and the end four days of radiotherapy). Resection was attempted 5 to 6 weeks after end of chemoradiotherapy. (B) Adjuvant group that received concurrent chemo-radiation after surgical resection. Results: Two (16.7%) patients out of 12 patients treated with neoadjuvant chemo-radiotherapy and 5 (38.5%) out of 13 in the surgery group survived after 36 months. These rates were not significantly different with per protocol and intention-to-treat analysis. The median survival time of patients in group A and B were 13.4 and 21.6 months, respectively, again not significantly different. Survival was significantly greater in patients with well differentiated adenocarcinoma in group B than in group A (p<0.004). Conclusions: According to this study we suggest surgery then chemoradiotherapy for patients with well differentiated gastric adenocarcinoma rather than other approaches. Additional studies with greater sample size and accurate matching relying on cancer molecular behavior are recommended.

  • Background: Tetracycline is an antibiotic widely used for the treatment of Helicobacter pylori infection, but its effectiveness is decreasing due to increasing bacterial resistance. The aim of this study was to investigate the occurrence of 16S rRNA mutations associated with resistance or reduced susceptibility to tetracycline ofHelicobacter pylori by real-time PCR (RT-PCR) assays from culture. Materials and Methods: Tetracycline susceptibility and minimal inhibition concentration (MIC) was determined by the Epsilometer test (Etest) method. A LightCycler assay developed to detect these mutations was applied to DNA extracted from culture. The 16S rRNA of these isolates was sequenced and resistance-associated mutations were identified. From 104 isolates of H. pylori examined, 11 showed resistance to tetracycline. Results: LightCycler assay was applied to DNA extracted from 11 tetracycline-susceptible and 11 tetracycline resistance H. pylori isolates. In our study the sequencing of the H. pylori wild types in 16 s rRNA gene were AGA 926-928 with MIC (0.016 to $0.5{\mu}g/ml$), while the sequencing and MIC for resistant were GGA and AGC, (0.75 to $1.5{\mu}g/ml$), respectively. Also we found a novel mutation in 2 strains with $84^{\circ}C$ as their melting temperatures and exhibition of an A939C mutation. Conclusions: We conclude that real-time PCR is an excellent method for determination of H. pylori tetracycline resistance related mutations that could be used directly on biopsy specimens.
