국내에서 서구화된 생활습관으로 인해 대사증후군 환자가 매년 증가되고 있는 추세이다. 대사증후군은 다양한 심혈관 및 간질환 그리고 당뇨와 같은 질환으로 위험성 높으며, 여러 합병증을 유발 할 수 있다. 이러한 질환을 진단하는데 임상적인 진단지표가 많이 활용되고 있으나 최근 생활습관정보를 기반으로 분석하여 자가진단 및 예방에 중점을 둔 연구가 활발하게 진행되고 있다. 그러나 임상에서 생활습관정보를 기반으로 질환진단에 활용하는데 미흡한 실정이다. 따라서 본 연구에서는 대사증후군 관련 환자를 대상으로 반복적으로 생활습관과 정확한 운동습관 정보를 수집하여 관리를 할 수 있는 시스템을 제안하고자 한다. 이를 위해 기족 생활습관관련 설문지 조사 방법은 반복적인 설문방법을 채택하여 앱상에서 수집하고 운동습관 정보는 웨어러블 디바이스를 이용하여 정확한 운동관련 정보를 수집할 수 있도록 하였다. 제안한 시스템을 이용하여 비만 및 대사증후군 환자의 생활습관 개선에 따른 지속적인 관리를 통해 예방에 도움이 될 것으로 기대하며, 향후 수집한 생활습관과 운동습관정보를 분석하여 임상에 활용할 수 있는 예측 모델을 개발하고자 한다.

The body composition and arterial compliance with advanced age increase the risks of cardiovascular diseases, but the elderly can perform rhythm exercise easily, which may positively influence their body composition and arterial compliance. Therefore, this study examined the effects of rhythm exercise training on the body composition and arterial compliance in elderly females. The subjects (n=20) were assigned randomly to either an exercise group (n=10, EX) or non-exercise control group (n=10, CON). The rhythm exercise training for 12 weeks consisted of 3 sessions per week with 60 minutes per session. In addition, the intensity was set to 11-14 of the Borg scale (6-20). The body composition and arterial compliance (pulse wave velocity (PWV)) were measured before and after training. The skeletal muscle mass in the EX was increased significantly (p=0.04) and the right (p=0.002) and left side (p=0.02) of the PWV in the EX were decreased significantly, but the skeletal muscle and both sides of the PWV in the CON were not changed. Elderly females could easily perform rhythm exercise training, which resulted in improvements of the skeletal muscle mass and arterial compliance. Therefore, rhythm exercise training may prevent or delay sarcopenia and reduce the risk of cardiovascular diseases.

This study was conducted to investigate the effects of plasma homocysteine concentration on the brachial-ankle pulse wave velocity between the normal homocysteine group and the asymptomatic high homocysteine group. 435 subjects who visited the general health examination center from April 1 to October 31, 2016, as well as to compare the direct correlation of the brachial-ankle pulse wave velocity, which indirectly reflects the homocysteine test and arterial stiffness, as a predictor of future cardiovascular outcome. As a result of the study, age, waist circumference, BUN, and plasma creatinine were significantly higher, and HDL was significantly lower in the high homocysteine group (> $15{\mu}mol/L$) than in the normal homocysteine group (< $15{\mu}mol/L$) (p=0.05). In addition, homocysteinemia was associated with smoking and drinking (p<0.001) and was significantly higher in males (p<0.001). The right and left brachial-to-ankle pulse wave velocities were significantly higher in the high homocysteine group (right p<0.001, left p=0.003) before calibrating the relevant variables. There was no significant difference between right and left brachial-to-ankle pulse wave velocities after calibrating the relevant variables. Therefore, further studies on the independent association of lowering homocysteine concentration and prevention of cardiovascular disease and the relationship between homocysteine and renal function are needed.

Soybean (Glycine max), as one of the foods with high plant proteins, contains a large amount of bioactive compounds and known to be effective in cardiovascular disease and obesity as well as in improving skin condition. The purpose of this study was to investigate the anti-photoaging effects of soybean fermented with Lactobacillus Rhamnosus ($Bio-Peptone^{(R)}$) by assessment of cytotoxicity against UVB, collagen synthesis after UVB-irradiation, tyrosinase activity, and melanin synthesis. Results showed that $Bio-Peptone^{(R)}$ protected skin fibroblasts against UVB-induced cytotoxicity and increased type I collagen synthesis. Furthermore, $Bio-Peptone^{(R)}$ significantly inhibited tyrosinase activity and reduced melanin contents. This study suggests that $Bio-Peptone^{(R)}$ has protective effects against UVB-induced skin damage. Thus, it is concluded that $Bio-Peptone^{(R)}$ is able to prevent skin damage against UVB and thus acts as anti-photoaging materials by protecting skin forming wrinkles and skin pigments.

To develop new high valuable Gugija (Lycium chinensis), biofunctionalities of Gugija standard species and its hybrids were investigated and compared with each water extracts and methanol extracts from Lycii Fructus, Lycii Folium and buds and Lycii Cortex Radicis. Among various biofunctionalities of Gugija standard species, antioxidant activity was showed the highest in methanol extracts from buds of Cheongwoon species (93%) and antihypertensive angiotensin I-converting enzyme (ACE) inhibitory activity was 84.1% in the water extracts from Lycii Cortex Radicis of Cheongyang NO.7. Futhermore, methanol extracts from Lycii Cortex Radicis of Myungan A-2 hybrid showed 93.1% of antioxidant activity and 96.9% of ACE inhibitory activity was also showed in the methanol extracts from Lycii Fructus of DO148-72(A11) hybrid. However, fibrinolytic activity and anticholesteromia HMG-CoA reductase inhibitory activity were weak or not detected in almost of Gugija standard species and its hybrids. Therefore, we finally selected Cheongwoon Gugija standard species (buds) and Myungan A-2 hybrid (Lycii Cortex Radicis) as good antioxidant sources and also DO148-72 (A11) hybrid (Lycii Fructus) as excellent antihypertensive ACE inhibitior sources for manufacturing functional food product.

The regulation of platelet aggregation is crucial for maintaining normal hemostasis, but abnormal or excessive platelet aggregation can contribute to cardiovascular disorders such as stroke, atherosclerosis, and thrombosis. Therefore, identifying substances that can control or suppress platelet aggregation is a promising approach for the prevention and treatment of these conditions. Artemisinin, a compound derived from Artemisia or Scopolia plants, has shown potential in various areas such as anticancer and Alzheimer's disease research. However, the specific role and mechanisms by which artemisinin influences platelet activation and thrombus formation are not yet fully understood. This study investigated the effects of artemisinin on platelet activation and thrombus formation. As a result, cAMP production were increased significantly by artemisinin, as well as phosphorylated VASP and IP₃R which are substrates to cAMP-dependent kinase by artemisinin in a significant manner. The Ca²⁺ normally mobilized from the dense tubular system was inhibited due to IP₃R phosphorylation from artemisinin, and phosphorylated VASP by artemisinin aided in inhibiting platelet activity via αIIb/β3 platelet membrane inactivation and inhibiting fibrinogen binding. Finally, artemisinin inhibited thrombin-induced thrombus formation. Therefore, we suggest that artemisinin has importance with cardiovascular diseases stemming from the abnormal platelets activation and thrombus formation by acting as an effective prophylactic and therapeutic agent.

Objective: This study was a preliminary study for the prevention programs for farmers' occupational diseases. It selected the priorities recognized by farmers, such as occupational diseases, and also identifies the effectiveness and feasibility of prevention programs among diseases recognized by farmers. Therefore, we plan to use it as basis data for future farmer safety and health programs. Method: The subjects of the study were farmers living in the region, selected through a snowball recruitment method, and a total of 671 people were targeted. The priority selection method was the Basic Priority Rating System (BPRS) method, and among the occupational diseases, programs to prevent musculoskeletal diseases, cardiovascular and respiratory diseases, and pesticide poisoning were surveyed on the effectiveness and feasibility of farmers. Results: Among occupational diseases, the highest priority was musculo-skeletal disease, followed by respiratory disease and pesticide poisoning. Among the programs for musculoskeletal disease, 'use of agricultural work convenience equipment and auxiliary tools' had the highest perceived effectiveness and feasibility. Among the five programs for pesticide poisoning, 'equipment of protective equipment such as pesticide protective clothing/glove' had the highest effectiveness at 67.4%, and 'compliance with pesticide use instructions' had the highest level of feasibility at 64.3%. Among the four programs to prevent respiratory diseases, 'wearing a dust mask or gas mask' was the highest at 65.5% in terms of both effectiveness and feasibility. Conclusion: When carrying out safety and health programs for farmers, the priorities recognized by farmers should be taken into consideration, and the program contents should also be developed taking into account the size of effect and feasibility recognized by farmers.

Many clinical trials have demonstrated the beneficial effects of garlic (Allium sativum) on general cardiovascular health. Aged garlic extract (AGE) is known to display diverse biological activities such as in antioxidant, anti-inflammatory and anticancer activities. However, few studies have been directed on the effect of AGE on cardiovascular function. In this study, we aimed to investigate the effect of AGE and its components on platelet activation, a key contributor in thrombotic diseases. In freshly isolated rat platelets, AGE and its components have shown inhibitory activities on thrombin-induced platelet aggregation. These in vitro results were further confirmed in an in vivo platelet aggregation measurement where tail vein injection of garlic oil and S-Allylmercapto-cysteine (SAMC) significantly reduced thrombin and ADP-induced platelet aggregation. Potential active components for antiplatelet effects of AGE were identified to be SAMC and diallyl sulphide through agonist-induced platelet aggregation assay. These results indicate that aged garlic extract can be a novel dietary supplement for the prevention of cardiovascular risks and the improvement of blood circulation.

Omega-3 fatty acids have been major research interests in medical and nutritional science relating to life sciences since after the epidemiologic data on Green3and Eskimos reported by several researchers clearly showed fewer per capita deaths from heart diseases and a lower incidence of adult diseases. Linolenic acid(LNA) is an essential fatty acid for human beings as well as linoleic acid(LA) due to the fact that vertebrates lack an enzyme required to incorporate a double bond beyond carbon 9 in the chain. In addition the ratio of omega-6 and 3 fatty acids seems to be important in terms of alleviation of heart diseases since LA and LNA competes for the metabolic pathways of eicosanoids synthesis. High consumption of omega-3 fatty acids in seafoods may control heart diseases by reducing blood cholesterol, triglyceride, VLDL, LDL and increasing HDL and by inhibiting plaque development through the formation of antiaggregatory substances like PGI$_2$, PGI$_3$ and TXA$_3$ metabolized from LNA. Omega 3 fatty acids also play an important role in neuronal developments and visual functioning, in turn influence learning behaviors. Current dietary sources of omega-3 fatty acids are limited mostly to seafoods, leafy vegetables, marine and some seed oils and the most appropriate way to provide omega-3 fatty acids is as a part of the normal dietary regimen. The efforts to enhance the intake of omega-3 fatty acids due to several beneficial effects have been made nowadays by way of food processing technology. Two different ways can be applied: one is add Purified and concentrated omega-3 fatty acids into foods and the other is to produce foods with high amounts of omega-3 fatty acids by raising animals with specially formulated feed best for the transfer of omega-3 fatty acids. Recently, items of manufactured and marketed omega-3 fatty acids fortified foodstuffs are pork, milk, cheese, egg, formula milk and ham. In domestic food market, many of them are distributed already, but problem is that nutritional informations on the amounts of omega-3 fatty acids are not presented on the labeling, which might cause distrust of consumers on those products, result in lower sales volumes. It would be very much wise if we consume natural products, result in lower sales volumes. It would be very much wise if we consume natural products high in omega-3 fatty acids to Promote health related to many types of adult diseases rather than processed foods fortified with omega-3 fatty acids.

Delirium is a syndrome characterized by impairement of consciousness, disorientation, disturbance of sleep-wake cycle, memory impairement, disturbance of perception. It is induced by many causes, which are CNS diseases(head trauma, vascular disease, brain tumor, etc), medical diseases(metabolic disorder, endocrine disturbance, cardiovascular disease) and drugs(anticholinergics, anticonvulsant, antipsychotics, cimetidine etc). Transdermal scopolamine which is usually used to prevent motion sickness has anticholinergic property, and so it can induce delirium. The authors report two cases of delirium induced by transdermal scopolamine. The cases shared common characteristics which were as follows : 1. All of two patients were elderly women. 2. Delirium symptom was abruptly occurred during trip after attaching scopolamine patches. 3. Delirium symptom was rapidly improved within 2-3 days. It is important to educate for both users and managers about directions for transdermal scopolamine patch usage to prevent delirium. And careful history taking is needed to diagnose delirium induced by transdermal scopolamine accurately.
