  • In the sequence of carbon tetrachloride hepatotoxicity, increased serum levels of a number of enzymes have been demonstrated in experimental animals. These observations, therefore, have served to help in detecting hepatic injury. The serological influence of chlorpromazine (CPZ) and iproniazid on the acute $CCl_4$ poisoning was executed in this investigation taking use of 6 albino rabbits (around 2 kg b.w.) in each group. By measuring of blood sugar level (Nelson-Somogyi method), S-GOT and S-GPT activities (Reitman-Frankel method), the pharmacological effects of the drugs was evaluated setting pretreated groups against the control. The results obtained were summarized as follows: 1. The intramuscular injection of $CCl_4$ led to increase the blood sugar level in first 3 hours and, after that, to decrease reasonably. But CPZ-pretreated group showed a tendency of increasing in compare with the control, and iproniazid-pretreated group inhibited evidently. 2. In S-GOT activity, the increased level was induced by $CCl_4$ in control. And CPZ-pretreated group showed a increased level until first day and decreased rapidly. But this property inhibited inhibited significantly by pretreating with iproniazid. 3. Although a single dose of $CCl_4$ increased the S-GPT activity, the more increasing trend was observed in CPZ-pretreated group. But these tendencies depressed remarkably in the iproniazid-pretreated group. It seemed to be attributed not to defend the $CCl_4$ toxicity but to be suppressed the enzyme systems in the liver by iproniazid that the blood sugar level and serum transaminase activities was decreased significantly in pretreating with iproniazid.

  • Purpose: The purpose of this study was to compare prescription patterns and clinical features according to clinical departments in sedative-hypnotic intoxication. Methods: This was a retrospective study of histories, substances of poisoning, acquisition routes, clinical courses, and outcomes of patients treated for acute intoxication in a single emergency medical center from January, 2011 to December, 2013. Results: A total of 769 patients were treated for acute intoxication, 281 patients ingested sedative hypnotics during the study period. Among 281 patients, 155 patients were prescribed by psychiatric department and 80 patients were prescribed by non-psychiatric department. Benzodiazepines were more likely to be prescribed by psychiatrists, and zolpidem was preferred by non-psychiatrists (p<0.001). Non-psychiatrists were more likely to prescribe short acting benzodiazepines than psychiatrists (p<0.001). However, there was no statistically significant difference in the clinical outcomes, including prevalence of admission to ICU, ventilator care, and length of stay in ICU. In patients prescribed by non-psychiatrists, there were more patients prescribed without psychiatric diagnosis and diagnosed as major depression disorder after hospitalization. Conclusion: To promote rational prescribing of sedative hypnotics, proper psychiatric evaluation should be performed before prescribing, and educational programs including the contents of interactions and side effects of sedative hypnotics are needed.

  • In order to know the morphological changes of liver in nitrate poisoning, the ultrastructural studies were carried out on the rabbit liver after potassium nitrate was administered orally at lethal dose, in single treatment, as acute case and at two different levels. 1.0 and 0.5g/kg of body weight daily for 43 and 60 days as chronic case, respectively, The results were summarized as followings: 1. In the hepatic cells of acute case, mitochondria were swollen, disappearance of cristae and variable in shape. Dilatation of rough endoplasmic reticulum and vacuoles containing degenerated cell organells were observed. Glyogen particles were decreased in number. Degenerated Kupffer cells were often seen in acute case. 2. In the hepatic cells of chronic case, there were increase of smooth endoplasmic reticulum, marked enlargement of rough endcplasmic reticulum, detachment of membrane bound ribosome and some rough endoplasmic reticulum changed into smooth endoplasmic reticulum. Secondary lysosome, abundant glycogen paricles and myelin-figure structures were also observed in the cytoplasm of the hepatic cells. The endothelial cells were proliferated in the area of the necrotic cells.

  • 본 연구는 강원도 일부 고랭지 농업 농민을 대상으로 농약 노출 실태와 농약 노출로 인한 급성 중독 증상 경험을 비교하기 위하여 농약 노출력과 급성 중독증상에 대한 설문을 강원도 강릉시 왕산면 대기리의 고랭지 농업지역 농민을 대상으로 면접식 설문을 실시하였다. 연구결과 농약 노출과 농약 사용 기간은 두 집단간에 차이가 없었으나 연간 살충제 사용 일수는 고랭지 농업 농민이 1년에 평균 35.9일로 일반 농업 농민의 14.4일보다 더 많이 사용하였다. 일일 살충제 사용 시간도 고랭지 농업 농민이 하루 6.7시간으로 일반 농업 농민의 2.8시간 보다 길었다. 농약 노출에 의한 급성 중독 점수도 고랭지 농업 농민에서 유의하게 높았다. 회귀분석 결과 급성 중독 증상은 제초제 노출과는 통계적으로 유의한 상관성이 없었으며 살충제 노출과는 밀접한 연관관계가 있었다. 또한 중독 증상으로는 '피부가 따갑고 가렵다', '머리가 어지럽거나 아프다', '온 몸에 힘이 빠진다', '눈이 따갑다', '구역질이 난다' 의 5개 문항에 있어서 고랭지 농업 농민이 더 많이 경험을 하였으며 '눈 앞이 흐려졌다', '의식을 잃고 쓰러진다', '전신이 마비되었다'. '말이 나오지 않았다'의 4개 문항은 양 군간에 차이를 보이지 않았다. 증상의 경험률은 전체적으로 52.9%였으며 농업 형태별로 보면 일반 농업지역은 51.1%, 67.9%로 매우 높은 편이었다. 증상별로 보면 두통의 경우 전체적으로는 40.7%였으나 고랭지 농업의 경우는 73.7%, 일반 농업의 경우는 35.3%였으며 피부증상의 경우에는 전체적으로 22.9%, 고랭지 농업 농민은 57.9%, 일반 농업 농민은 17.2%였다. 이상의 연구결과를 볼 때, 고랭지 농업 농민은 일반 농업 농민보다 농약 노출이 많은 것을 알 수 있으며 추후 고랭지 농업 농민들의 농약 노출에 대한 건강영향 평가 및 농약 노출을 감소시켜 건강장해를 예방하기 위한 다양한 연구 및 행정적 노력이 필요할 것으로 사료된다.

  • Tetramine toxicity due to sea snail ingestion is generally mild and has a good prognosis. Tetramine toxicity acts on the acetylcholine receptor, affecting the neuromuscular junction and autonomic nervous system. A 78-year-old female patient visited the emergency room with vomiting and dyspnea after eating sea snails. At the time of admission, the vital signs recorded were 140/80 mmHg-105/min-24/min-36.5℃, and 90% oxygen saturation. Arterial blood test revealed hypercapnia (pCO2 58.2 mmHg) and respiratory acidosis (pH 7.213, HCO3- 22.5 mmol/L), whereas other blood tests showed no specific findings. Due to decreased consciousness and hypoxia, endotracheal intubation and mechanical ventilation were administered to the patient. Successful weaning was accomplished after 12 hrs, and the patient was discharged without any further complications. Although tetramine toxicity rarely results in acute respiratory failure due to paralysis of the respiratory muscle, caution is required whilst treating the patient.

  • Three German Shepherd dogs (5 years old, 30 kg, male; 4 years old, 23 kg, female; 4 years old, 24 kg, female) with history of acute vomiting, hemorrhagic diarrhea, anorexia and dullness were admitted to veterinary clinic in the military working dogs training corp (MWDTC). All of them showed same symptoms after ingestion the $'PREVNTIC^{(R)}'$ collar to control ecto-parasites infection in field. One dog was operated by gastrotomy and the $5{\sim}6$ pieces of the $'PREVNTIC^{(R)}'$ collar were removed. The dog was completely cured by intensive care within 2 hours after $'PREVNTIC^{(R)}'$ collar ingestion. However, two dogs were operated by gastrotomy and intensive care over 24 hours after $'PREVNTIC^{(R)}'$ collar ingestion but died. In autopsy, the $5{\sim}6$ pieces of hard materials were found in the stomach, and severe thickness, congestion hemorrhage and swelling of the stomach walls and mucous membrane were observed. In these cases, it was suggested that the first aid of treatment such as gastrotomy within two hours after $'PREVNTIC^{(R)}'$ collar ingestion as soon as possible was helpful for attenuating of toxicosis.

  • A 9-month-old, intact female mixed dog was referred to Veterinary Medical Teaching Hospital of Gyeongsang National University with symmetrically enlarged and protruded upper jaw. The patient was diagnosed as acute renal failure due to ethylene glycol poisoning and was treated for 1 month in a local animal hospital. In spite of treatment, the patient proceeded to chronic renal failure. Also, the patient's upper jaw begun to enlarge continuously. To evaluate this upper jaw, radiographic examination was performed. Skull radiographs revealed thickening of maxilla, decreased bone opacity, cortical thinning, loss of lamina dura and periodontal space in the maxilla. Diagnosis of rubber jaw syndrome is based on clinicial signs, radiographic findings and laboratory evidence of chronic renal failure due to ethylene glycol poisoning.

  • Green tobacco sickness is an illness caused by dermal exposure to nicotine. The common symptoms of the disease include dizziness, headache, nausea, vomiting, severe general weakness, fluctuations of blood pressure or heartbeat, abdominal cramping, chills, increased sweating, salivation, and difficulty breathing. A 79-year-old female arrived at the emergency room for an evaluation of sudden onset dizziness. Magnetic resonance imaging and angiography of the brain did not show any relevant abnormal findings. Four days later, with supportive care, she said that she had harvested green tobacco for six hours on the day of admission and the tobacco harvest was the first time in her life. She sweated excessively during the hot and humid weather and the tobacco leaves were wet from rain the night before. The serum cotinine tested at five days of admission was 16ng/ml. She was diagnosed with acute nicotine poisoning by her clinical symptoms and the half-life of cotinine in the blood.

  • Methemoglobin is generated by the oxidation of ferrous iron to ferric iron within a hemoglobin molecule. Methemoglobin is unable to bind and transport oxygen, resulting in methemoglobinemia, which can lead to fatal tissue hypoxia. The most common cause of methemoglobinemia is poisoning by oxidizing agents such as dapsone, benzocaine, and primaquine. However, methemoglobinemia can also be caused by normal dietary sources. We present two cases of methemoglobinemia that developed after a normal diet in two male patients. In this case report, the patients suddenly developed dyspnea and cyanosis after eating the same meal. They had no history of suspected poisoning, such as the use of drugs, exposure to chemicals, or gas inhalation. Their symptoms did not improve even after a high dose of oxygen was administered; further, an abnormal 'oxygen saturation gap' was observed. Because of CO-oximetry, the methemoglobin levels of the patients were 50.0% and 46.6%, respectively. We administered methylene blue (1 mg/kg), and the patients recovered completely without any complications. Emergency physicians should, therefore, be aware that methemoglobinemia can also be caused by normal dietary sources. In addition, if the source and route of contamination are unclear, an epidemiological investigation should be conducted.
