현재 국내 인체 이식용 전자 의료기의 이식건수는 매년 약 1800 여건으로 해마다 증가하고 있으며 그 연령대도 다양한 작업환경에 노출되는 청장년층으로 급속히 확대되어 가고 있다. 이러한 이식용 의료기는 인공 심장 박동기, 이식형 제세동기, 진통억제를 위한 이식형 전기 펄스 발생기, 이식형 약물주입기 등을 포함한다. 그러한 기기들은 미세한 생체 신호에 따라 반응하기 때문에 생체 신호이외의 잡음에 의한 오동작은 절대적으로 피해져야 하며 경우에 따라 생명위협과도 직결된다. 본 논문에서는 현재사용 중인 이식형 전자의료기들의 구조와 동작원리, 다양한 작업 환경 하에서 잡음의 영향을 고찰하고, 잡음에 의한 오동작의 방지 방안을 고찰함으로써 전자의료기 인체 삽입자의 작업환경에 따른 안전문제를 제고하고자 한다.

Toxoplasmosis is an important cause of foodborne, inflammatory illnesses, as well as congenital abnormalities. Currently available therapies are ineffective for persistent chronic disease and congenital toxoplasmosis or have severe side effects which may result in life-threatening complications. There is an urgent need for safe and effective therapies to eliminate or treat this cosmopolitan infectious disease. The aim of this study was to investigate the in vitro anti-Toxoplasma activities of Suaeda maritime, one of the halophytes, using tachyzoit of T. gondii RH strain infected HeLa cells. As the results, the selectivity of Suaeda maritime extract was 6.63, which was higher than Sulfadiazine selectivity (2.06). Also, we perfomed the cell proliferation inhibition test and the morphological study to evaluate the anti-T. gondii activity of Suaeda maritime extract with HeLa cells. As the results, the inhibition rate of the Suaeda maritime extract was high inhibition rate. This indicates that the Suaeda maritime extract may be used for new anti-T. gondii agent.

1944년 임상적으로 사용되기 시작한 스트렙토마이신은 전세계 결핵환자의 치료약제로 널리 사용되고 있다. 그러나 스트렙토마이신의 알레르기성 과민반응의 경우 그 발생빈도가 대단히 낮고 그로인한 사망률도 극히 낮은 안전한 약제임에도 불구하고, 오히려 그 부작용이 과장되게 알려져 있어 사용하기를 꺼리는 경향이 있다. 임상증세로는 주로 피부, 호흡기, 순환기, 소화기의 장기와 관련되어 발생한다. 초회 주사시의 쇼크는 자신도 모르는 사이에 이미 감작되었을 가능성이 있으며 주사를 계속 맞다가 발생하는 수도 있다. 무엇보다도 예방이 가장 중요하며 혼자의 과거 알레르기반응의 유무 및 약물 사용력을 정확히 파악한 후 사용하여야 한다

Objectives : Considering the impact of depressive illness on physical and mental health of both mother and fetus, specification of a treatment algorithm for depressive disorder during pregnancy is legitimated. This article provides a systemic review of treatments for depressive disorder during pregnancy and lactation. Methods : According to the search strategy of the Clinical Research Center for Depression of Korean Health 21 R & D Project, PubMed and EMBASE were searched using terms with regard to the treatment of depressive disorders during pregnancy and lactation. Reference lists of related reviews and studies were searched. In addition, relevant practice guidelines were searched using the PubMed. All identified clinical literatures were reviewed and summarized in a narrative manner. Results : Pharmacotherapy during pregnancy and lactation requires a comprehensive assessment of the risks and benefits of treatment for both mother and fetus or neonate. Recently, there is growing evidence that the use of tricyclic and selective serotonin reuptake inhibitors during pregnancy and lactation does not result in increased risks of teratogenicity. Treatment strategies are described according to the point of time of pregnancy or lactation. FDA categories for antidepressants during pregnancy and lactation are described. In addition, issues regarding to the electroconvulsive therapy and psychosocial treatment are discussed. Conclusion : The treatment option for depressive disorders during pregnancy and lactation depends on the severity of depressive illnesses of the individual patient. For mild to moderate depression, the non-pharmacological treatment should be considered first. For moderate to severe depression, pharmacotherapy should be administered in addition to the psychosocial treatment. ECT is recommended for depressive disorder of severe intensity. As the research knowledge is limited, the recommendations should based on the best judgement of psychiatrists.

Objectives : To investigate the clinical features of drug-induced liver injury (DILI) and traditional Korean medicine (TKM) -based management. Methods : A female patient diagnosed with DILI caused by Western drugs had been treated with Oriental therapies, then the subjective clinical outcome and biochemical parameters were monitored. Results : A 73-year-old female had taken Western drugs (nonsteroidal anti-inflammatory and skeletal muscle relaxants) for about 3 months, and complained of severe abdominal discomfort and tiredness. Her RUCAM score was 9, which met the criteria for DILI (AST 90 IU/L, ALT 100 IU/L, ALP 191 IU/L, and GGT 614 IU/L). She was treated with herbal drugs, moxibustion, and acupuncture, and her symptoms completely resolved, with normalized hepatic enzymes within two weeks. Conclusions : This case report provides a clinical characteristic for a typical DILI caused by Western medicine, and shows an example of a TKM-based application.

Alzheimer's disease (AD) is the most common cause of dementia, showing progressive neurodegeneration. Although oral medications for symptomatic improvement still take a huge part of treatment, there are several limitations caused by pharmacology-based real world clinic. In this respect, non-pharmacologic treatment for AD is rising to prominence. Transcranial direct current stimulation (tDCS) is a one of the non-invasive neuromodulation technique, using low-voltage direct current. In terms of safety, tDCS already has been proven through numerous previous reports. This review focused on behavioral, neurophysiologic and histopathologic improvement by applying tDCS in AD rodent models, thereby suggesting reliable background evidence for human-based tDCS study.

Recently, the interest in the extension of human life and personal health has been increased. Accordingly, many researchers in a pharmacy and a medical world have been making efforts to improve the sustained drug release property and the stability of drug release property in a body. Many biological researches have demonstrated that chitosan derivatives are effective, safe absorption enhancers that can improve the delivery efficiency of drug and vaccine, and they are suitable for controlled drug release because they have good stability, bio-compatibility, and biodegradability. In this study the experiment was performed in vivo by utilizing chitosan nanoparticles as a biopolymer to control drug delivery rate at an optimal temperature, pH, and concentration. It was observed that nanoparticles containing insulin could effectively control the blood glucose at a low level.

Drug delivery technologies are patent protected formulation technologies that modify drug release profile, absorption, distribution, and elimination for the benefit of improving product efficacy and safety, as well as patient convenience and compliance. The most commonly used transdermal system is the skin patch using various types of technologies. Compared with other method of dosage, it is possible to use for a long term. It is also possible to stop the drug dosage are stop if the drug dosage lead to side effect. Polysaccharide, such as karaya gum and locust bean gum(LBG)/water-soluble chitosan oligomer(WSCO) were selected as base materials of TDS. Also, these polymers were characterized in terms of enhancers, tacrine contents. Among these polysaccharide, the permeation rate of karaya gum matrix was fastest in tacrine such as lipophilic drug in vitro. We used glycerin, PEG 400, and PEG 800 as enhancers. Therefore, transdermal absorption of tacrine could be improved by changing vehicle composition or by using penetration enhancers. Especially it would be anticipated that the high permeation efficacy could be obtained by using vehicle that has enhancing effect for itself and by adding enhancers to it.

Biological compounds (caffeic acid, rosemarinic acid, and chlorogenic acid) from mulberry leaf extracts were administered to mice in order to confirm their stability. All male and female mice survived upon a 4,000 mg/g dose in an acute toxicity test, and they also survived after injection of 2,000 mg/kg for 13 weeks repeatedly. Therefore, the level of toxicity was not high. In a comparison of the control and test groups, there were no significant differences upon naked eye inspection, and the weights of stomachs infected by Helicobacter pylori were not significantly different. Regarding the effects on immune cells, NO of macrophages decreased more than that of control when medicine was administered. The spleens of the female mice group proliferated slightly in LPS and Con A within 48 hr, whereas the other test group showed a similar level and the cell toxicity of natural killing cells decreased. Therefore, we concluded that caffeic acid, rosemarinic acid, and chlorogenic acid from mulberry leaf extracts are not harmful for the treatment of infected patients the development as a healthy functional food.
