본 연구는 목초액의 섭취가 훈련된 흰쥐의 항산화방어기전에 미치는 영향을 알아보기 위하여 수행되었다. 실험대상으로는 Sprague-Dawley계 수컷 흰쥐를 사용하였는데 실험그룹은 비운동 대조군과 운동 대조군, 목초액 섭취 비 운동 대조군, 목초액 섭취 운동 대조군으로 나누어 수행하였는데 체중과 혈중성분 변화, 글리코겐 함량, SOD 활성 수준, MDA 함량에 관한 분석을 하였다. 체중과 체지방(장간막, 복막후, 부고환)은 각 그룹 간에 유의한 차이가 없었고, TG와 FFA 농도도 목초액 섭취로 인한 차이는 없었다. Glucose 농도는 대조군 보다 운동군에서 유의한 차이를 나타내었으나 목초액 섭취로 인한 차이는 없었다. 목초액 투여 운동군에서의 SOD 활성은 다른 그룹보다 유의하게 높았다. 운동 대조군에서의 MDA 함량은 비운동 대조군보다 유의하게 낮게 나타났으나 대조군과 목초액 투여군 간의 차이는 없었다. 결론적으로 운동과 목초액 섭취는 산화적 스트레스의 감소에 긍정적인 영향을 줄 것으로 예상된다.

Purpose: To investigate the caustic ingestion in children among different continents according to demographic characteristics (core purpose), main symptoms, common caustic agents, signs and symptoms, management, treatment and complications. Methods: This systematic review was performed by searching the databases Science Direct, ProQuest, Google Scholar, and PubMed, electronically and manually. We included studies that were published from 1980 to 2013, at University of Medical Sciences of Tabriz, Iran. A strategic search was performed with keywords including caustic, corrosive, ingestion and children, and was limited to articles in English and Persian. Statistical analysis was performed by SPSS ver. 18. Results: Of 63 selected articles of caustic ingestion with 9,888 samples, the proportion of Africa was 3 articles (4.8%) and 95 samples (1%), America 9 articles (14.3%) and 305 sample (3%), Asia 29 articles (46%) and 2,780 samples (28.1%), Europe 17 articles (27%) and 3,002 samples (30.4%), and Oceania 5 articles (7.9%) and 3,706 samples (37.5%). The average age was in the Africa $3.07{\pm}2.02years$, America $3.17{\pm}1.83years$, Asia $3.34{\pm}1.58years$, Europe $3.58{\pm}2.09years$ and Oceania $3.52{\pm}2.02years$. Sex distribution was in Africa 76 males (0.91%) and 19 females (0.23%), America 49 males (0.58%) and 41 females (0.49%), Asia 1,575 males (18.76%) and 1,087 females (12.95%), Europe 1,018 males (12.13%) and 823 females (9.8%), and Oceania 1,918 males (22.85%) and 1,788 females (21.3%). Statistical analysis of the data indicated higher consumption in Europe and Oceania in the boys with higher average age of years. Conclusion: The comparison of caustic ingestion indicated that the cause substances of caustic ingestion in children are different among continents, therefore prevention strategy and different treatment guidelines among continents will be needed.

Purpose: Alcohol is one of the most commonly co-ingested agents in deliberate self-poisoning (DSP) cases presenting at the emergency department (ED). The increased impulsivity, aggressiveness, and disinhibition caused by alcohol ingestion may have different clinical features and outcomes in cases of DSP. This study investigates whether alcohol co-ingestion affects the clinical features and outcomes of DSP patients in the ED. Methods: This was a single-center retrospective study. We investigated DSP cases who visited our ED from January 2010 to December 2016. Patients were classified into two groups: with (ALC+) or without (ALC-) alcohol co-ingestion. The clinical features of DSP were compared by considering the co-ingestion of alcohol, and the factors related to discharge against medical advice (AMA) of DSP were analyzed. Results: A total of 689 patients were included in the study, with 272 (39.5%) in the ALC+ group. Majority of the ALC+ group patients were middle-aged males (45-54 years old) and arrived at the ED at night. The rate of discharge AMA from ED was significantly higher in the ALC+ group (130; 47.8%) compared to the ALC- group (p=0.001). No significant differences were obtained in the poisoning severity scores between the two groups (p=0.223). Multivariate analysis revealed that alcohol co-ingestion (odds ratio [OR]=1.42; 95% confidence interval [CI], 1.01-1.98), alert mental status (OR=1.65; 95% CI, 1.17-2.32), past psychiatric history (OR=0.04; 95% CI, 0.01-0.28), age >65 years (OR=0.42; 95% CI, 0.23-0.78), and time from event to ED arrival >6 hrs (OR=0.57; 95% CI, 0.37-0.88) were independent predictive factors of discharge AMA (p=0.043, p=0.004, p=0.001, p=0.006, and p=0.010, respectively). Conclusion: Our results determined a high association between alcohol co-ingestion and the outcome of discharge AMA in DSP patients. Emergency physicians should, therefore, be aware that DSP patients who have co-ingested alcohol may be uncooperative and at high risk of discharge AMA.

The present study was developed in order to evaluate the effect of five essential oils on the workers of the leaf-cutting ants; Atta sexdens rubropilosa and Acromyrmex subterraneus molestans by contact with a treated surface and ingestion with a treated leaves.. The essential oils of cinnamon, clove and mustard had generally more effective with 5, 10 and 15% concentrations after 24, 48, 72 and 96 h against workers of A. sexdens rubropilosa and A. subterraneus molestans in contact bioassay, but mustard was the most effective in ingestion bioassay on both species. On the other hand, there was no significant difference among the essential oils with 1% concentration and control after 24, 48 and 72 h of treatment in contact and ingestion bioassays against workers of A. sexdens rubropilosa . However, Andiroba oil had less efficiency values in all concentrations been used. Therefore, the essential oils of mustard, cinnamon and clove have contact and ingestion effects on workers of A. sexdens rubropilosa and A. subterraneus molestans, and may be promising on the leaf-cutting ant control.

A risk assessment of environmental media was performed for the inhabitants in the area of the abandoned Nokdong metal mine. Soil, groundwater, and crop samples were collected from September to October 2008 around the mine. After pretreatment of these samples, metal concentrations were measured, and a risk assessment was performed using the Korean soil-contamination risk assessment guidelines. Lead (Pb) and arsenic (As) intake rates were the highest for inhalation of soil dust. The cancer risks from ingestion of As-contaminated groundwater, inhalation of As-, Cd-, and Pb-contaminated soils, and contact of As-contaminated soils exceeded the acceptable risk. The sum of all carcinogenic risks was $9.29{\times}10^{-3}$. The non-carcinogenic risk was highest for ingestion of As-contaminated water (11.0), followed, in descending order, by inhalation of Hg-contaminated soil and ingestion of Pb-contaminated water. Most of the risks were associated with As, Cd, Pb, and Hg contamination, and therefore, these metals were considered to be potential toxic carcinogens and non-carcinogens for humans in this area. In this study, the non-carcinogenic risks of ingestion of contaminated water or crops, as well as those associated with the inhalation of soil dust were observed.

This study assessed the stabilization of fluorine (F)-contaminated soil using calcium hydroxide (Ca(OH)₂) and the consequent changes in human health risk. The bioavailable F decreased to 3.5%, (i.e., 57.9 ± 1.27 mg/kg in 6% Ca(OH)₂-treated soil sample) from 43.0%, (i.e., 711 ± 23.4 mg/kg in control soil sample). This resulted from the conversion of water-soluble F to stable calcium fluoride, which was confirmed by XRD spectrometry. Soil ingestion, inhalation of fugitive dust from soil, and water ingestion were selected as exposure pathways for human health risk assessment. Non-carcinogenic risks of F in soils reduced to less than 1.0 after stabilization, ranging from 4.2 to 0.34 for child and from 3.0 to 0.25 for adult. Contaminated water ingestion owing to the leaching of F from soil to groundwater was considered as a major exposure pathway. The risks through soil ingestion and inhalation of fugitive dust from soil were insignificant both before and after stabilization, although F concentration exceeded the Korean soil regulatory level before stabilization. Our data suggested that substantial risk to human health owing to various potential exposure pathways could be addressed by managing F present in soil.

The purpose of this study is to investigate the preference for purchase and ingestion of Korean traditional food Kimchi among the different age groups in order to find a way to increase Kimchi consumption. The result of a questionnaire is from 51 male respondents(14.6%) and 299 female ones(85%). This indicates that most of the female respondents buy Kimchi. Second, 61.7% of the respondents have experience purchasing ready-made Kimchi. Third, the most preferred purchase place of Kimchi is a big mart or a department store. Fourth, the important factors of purchasing come nutrition, price, brand, color or package in that order. Also, 60.9% of respondents show that they "should eat Kimchi". Fifth, the reason of eating Kimchi is taste in the age groups under 20s and 30s and above 50s. Lastly, the analysis on the importance of ingestion shows as follows: respondents in their 20s are 57 persons(16.3%), 30s 59(16.9%), 40s 162(46.3%), and 50s 72(20.6%), showing 40s the highest among them.

Anisakis is a parasite with life cycles involving fish and marine mammals. Human infection, anisakiasis, occurs with the ingestion of raw infected seafood and usually presents with acute or chronic gastrointestinal symptoms from esophageal or gastric invasion. We report a rare caseinvolving the oral cavity. A 39-year-old male presented with oral and sub-sternal pain of one day duration after eating raw cuttlefish. Physical examination revealed areas of erythema and edema with a central white foreign particle on the labial and buccal mucosa. With microscopic field we could remove the foreign material from the lesions. The foreign material was confirmed to be Anisakis. Anisakis was also removed from the esophagus by esophagogastroduodenoscopy. The patient was discharged the following day without complication. Anisakiasis is frequently reported in Korea and Japan, countries where raw seafood ingestion is popular. The symptoms of acute anisakiasis include pain, nausea, and vomiting and usually begin 2-12 hours after ingestion. The differential diagnosis includes food poisoning, acute gastritis, and acute pancreatitis. A history of raw seafood ingestion is important to the diagnosis of anisakiasis. Treatment is complete removal of the Anisakis to relieve acute symptoms and prevent chronic granulomatous inflammation.

In 30 rats divided into salt, ethanol and salt plus ethanol groups, the effect of ethanol on the course of hypertension induction with the salt ingestion was studied. The results obtained from the present study are as follows. 1) In salt group mean arterial blood pressure elevated to plateau (about 140 mmHg) in two weeks and the increased blood pressure was well maintained throughout entire experimental period. 2) By four weeks after ethanol ingestion, mean arterial blood pressure of ethanol group was slightly decreased followed thereafter by slow restoration to control value. And it was believed that decline of blood pressure observed in this case probably was not resulted from cardiac depression. 3) As mean arterial pressure in salt plus ethanol group remained rather low compared with that of salt group, it was suggested that ethanol may have a dose reduction effect in the course of hypertension induction by excessive salt ingestion. It was, however, not possible from the result of present study to decide that low blood Pressure in this group was resulted whether from enhanced sodium excretion activity of ethanol or from effect on blood pressure of ethanol itself.
