Sleep quality among university students is important, especially for their physical and psychosocial wellbeing. This study was conducted to investigate the level of smartphone addiction and stress among university students, and to estimate the effects of those variables on sleep quality. Data were collected from August 1st to 14th, 2018 using an online self-report survey to measure demographics including daily activity and indulgence foods, smartphone addiction, perceived stress scale, and the Pittsburgh Sleep Quality Index (Korean version). Collected data were analyzed by independent t-tests, ANOVA, Pearson's correlation coefficients, and multiple regression. The results showed that smartphone addiction, stress, and sleep quality had positive correlation in each relation. Multiple regression analysis showed that the predictors of sleep quality were smartphone addiction (${\beta}=0.041$, p=.001) and stress level (${\beta}=0.177$, p=.001), and the regression equation explained 24.9% of sleep quality. Therefore, higher levels of smartphone addiction and stress were associated with lower sleep quality. Based on these results, it is necessary to reduce unnecessary use of smartphone usage, as well as to develop and apply programs for university students to improve their sleep quality.

Alcoholics increased susceptibility to microbial infection that is associated with decreased immunity. but there has been little experimental evidence to support alcoholics-induced increase of microbial infection directly in non-specific immunity. Therefore, we were used the method of phagocytic-plaque including all the stimulating factors for the phagocytosis, subtypes of lymphocytes and T-lymphocyte proliferation. The experimental groups were divided into 3 groups: (1) alcoholics who were hospitalized less than 1 week (newly hospitalized alcoholics), (2) alcoholics who were hospitalized more than 2 weeks (old hospitalized alcoholics), (3) healthy blood donors. We have studied 98 alcoholics and 35 healthy blood donors and control groups. A physician has checked the biological markers and diagnosed the body-condition alcoholics. The immunity and non-specific immunity on the alcoholics were analyzed by using the simultest kit and flow cytometry. Proliferation of the lymphocytes was analyzed by the phytohemmagglutinine mitogen. Phagocytosis and migration properties of leukocytes were identified on the layer formed by Staphylococcus aureus Cowan I strain. Biological markers of alcoholics and control groups, by such as blood glucose, ${\gamma}$-glutamyl transpeptidase and mean corpuscular volumes of red blood cells, were determined by biochemical and hematological methods. Compared with control groups, cluster of differentiation (CD)3+, CD8+ and CD19+ in alcoholic were more decreased except CD4+/CD8+ ratio. Proliferation of the T-lymphocytes, phagocytosis and migration properties of the leukocytes in alcoholics were decreased compared with those of control groups. According to the results observed in our experiment, they can be summerized as follows: 1, Cellular, humoral and non-specific immunities, are markedly decreased in alcoholics than those in control groups. 2. It is inferred that Phagocytic plaque formation is a very useful method to evaluate phagocytosis and migration properties of the alcoholic leukocytes 3. It is thought that the subtypes of lymphocytes, especially CD4+/CD8+ ratio, are essential methods to analyzed the alcoholic immunity. 4. Specific and non-specific immunity on the old hospitalized alcoholics was slightly increased, which depends upon the alcoholic medication.

Narcolepsy is a sleep disorder, which is characterized by excessive daytime sleepiness (EDS) that is typically associated with cataplexy, sleep fragmentation and other REM sleep-related phenomenon such as sleep paralysis and hypnagogic hallucination. Narcoleptic symptoms can be developed from various medical or neurological disorders. A 17-year-old male patient admitted for the evaluation of EDS which started three-month ago. He slept more than 18 hours a day with cataplexy and hypnagogic hallucination. He was obese with body mass index (BMI) of 30.4 kg/$m^2$. After admission he was newly diagnosed to the thyrotoxicosis. T3 391.2 ng/dL (60-181), free T4 4.38 ng/dL (0.89-1.76), TSH <0.01 ${\mu}IU$/mL (0.35-5.5) were measured. His pulse rate ranged 70-90 beats per minute and blood pressure ranged 150/100-120/70 mmHg. Polysomnography revealed many fragmentations in sleep with many positional changes (81 times/h). Sleep onset latency was 33.5 min, sleep efficiency was 47.9%, and REM latency from sleep onset was delayed to 153.6 min. REM sleep percent was increased to 27.1%. Periodic limb movement index was 13.4/h. In the multiple sleep latency test (MSLT), average sleep latency was 0.4 min and there were noted 3 SOREMPs (Sleep Onset REM sleep period) on 5 trials. We couldn't discriminate the obvious sleep-wake pattern in the actigraph and his HLA DQB1 $^*0602$ type was negative. His thyroid function improved following treatment with methimazole and propranolol. Vital sign maintained within normal range. Cataplexy was controlled with venlafaxine 75 mg. Subjective night sleep continuity and PLMS were improved with clonazepam 0.5 mg, but the EDS were partially improved with modafinil 200-400 mg. Thyrotoxicosis might give confounding role when we were evaluating the EDS, though sleep fragmentation was one of the major symptoms of narcolepsy, but enormous amount of it made us think of the influence of thyroid hormone. The loss of sleep-wake cycle, limited improvement of EDS to the stimulant treatmen, and the cataplexy not supported by HLA DQB1 $^*0602$ should be answered further. We still should rule out idiopathic hypersomnia and measuring CSF hypocretin level would be helpful.

Respiratory failure is the most serious manifestation and usual cause of death in acute organophosphate poisoning, and is common in acute cholinergic crisis. But the respiratory failure may appear suddenly in a patient who is recovering from the cholinergic crisis, even while receiving conventional therapy. These are case report of 37 years old male and 24 years old female with intermediate syndrome in organophosphate poisoning. The two patients ingested organophosphate(fenthion and mixture of DDVP with chlorpyrifos respectively) incidentally and in a sucide attempt respectively. After apparent recovery from the cholinergic crisis with a conventional therapy but before the expected onset of delayed polyneuropathy, the respiratory failure appeared suddenly with a muscular weakness, affecting predominantly the proximal limb muscles, neck flexors, territories of several motor cranial nerves. The two patients needed mechanical ventilatory support and recovery from the intermediate syndrome was complete in both patients, although one subsequently developed hypoxic encephalopathy. The clinical manifestation and electrophysiologic study support the clinical diagnosis of intermediate syndrome. The syndrome carries a risk of death. because of respiratory paralysis, if not recognized early and treated adequatedly. Prompt endotrachial intubation and mechanical ventilatory support is the cornerstone of treatment of the intermediate syndrome. Therefore, all patient should be observed in a hospital for up to 5 days after poisoning.

2000년도 노벨 의학상은 스웨덴의 아비스 칼슨 박사 등 3명 이 수상했다. 그들은 신경전달 물질(neurotransmitter) 중 도파민 (dopamine)과 시냅스(synapse)에 관한 연구로 항 우울제 치료제인 프로작 (prozac)을 개발하여 신경, 정신질환 치료제 개발에 기여한 공로였다. 도파민과 GABA는 신경전달 물질 중의 하나로 도파민은 운동, 정서, 행동, 희노애락 등을 조절하는 것으로 이상 분비될 때 파킨스씨병, 정신분열증, 우울증 등을 유발시킨다. GABA는 억제성 신경전달물질로 이상 분비시 간질 등을 유발시킨다. 도파민과 GABA의 분비는 시냅스 후(postsynapse) 수용체에서 그 기능이 조절된다. 그러나 마약성인 코카인, 헤로인, 몰핀, 암페타민 등 중 독성약물뿐만 아니라 일상 생활에서 흔히 접할 수 있는 흡연, 술 등에 의해서도 그 분비 이상을 초래한다. 따라서 본 논단에서는 최근 뇌신경생물 실험실에서 진행되고 있는 신경전달 물질 중에 도파민 및 GABA 분비에 대 한 연구결과를 바탕으로 소개 하고자 한다.
