Quality stability of the herb pill coated with edible oils containing rosemary was investigated. Herb pills were made of herb powders such as Panax ginseng, Cinnamomum cassia, Lycium chinense, Zyzyphus jujuba and Zingiber officinale. Rapeseed oil and lubriol were used as edible coating oil. After herb pills coated with edible oils with or without rosemary were stored at 40℃ for 180 days, the microbial viable cell counts and peroxide values(POV) of the herb pill were investigated. After 180 day storage, POVs of herb pills with only rapeseed oil or lubriol were 0.51 and 0.49 meq/kg, respectively. However, when rosemary was added in herb pills the POVs were decreased to 0.30 and 0.39 meq/kg, respectively. The addition of rosemary to the rapeseed oil and lubriol tended to decrease the microbial viable cell counts of the herb pill. The microbial viable cell counts of rapeseed oil and lubriol were 940 and 820CFU/g, respectively after 180 days of storage. However, these levels were suppressed to 720 and 640CFU/g by the resemary addition. on the other hand, the ginseng saponin content of herb pills was not affected by the rosemary addition during storage.

Anti-hyperlipidemic Effects of Red Ginseng Acidic Polysaccharide from Korean Red Ginseng
Kwak, Yi-Seong,Kyung, Jong-Soo,Kim, Jong Soo,Cho, Jae Youl,Rhee, Man-Hee Pharmaceutical Society of Japan 2010 Biological & pharmaceutical bulletin Vol.33 No.3
<P>It has been reported that red ginseng acidic polysaccharide (RGAP), isolated from Korean red ginseng, displays immunostimulatory and anti-tumor activities. In a follow-up study, we have carried out a study on the anti-hyperlipidemic effects of RGAP using hyperlipidemic rats acutely induced by Triton WR1339 or corn oil intravenously injected. Oral administration of RGAP (100 to 1000 mg/kg) dose-dependently reduced the serum levels of triglyceride (TG) up-regulated by Triton WR1339, an inducer of endogenous model hyperlipidemia. Moreover, RGAP treatment was shown to significantly decrease the levels of non-esterified fatty acid (NEFA) concomitant with TG reduction. However, such reduction effects were not observed in cases of total cholesterol (TC) and phospholipid levels increased under the same conditions, although there was an inhibitory tendency. Similar suppressive patterns were also seen in hepatic parameters (total lipids and TG) under the same conditions. The exogenous hyperlipidemic rat condition triggered by corn oil also supported the anti-hyperlipidemic activity of RGAP in serum and hepatic parameters of TG and NEFA. Interestingly, RGAP significantly enhanced the serum activity of lipoprotein lipase, a key hydrolytic enzyme of lipid molecules in lipoprotein, in a dose-dependent manner up to 80%, implying potential involvement of this enzyme in lowering TG and NEFA by RGAP. Therefore, our data suggest that RGAP may play an additional role in reducing hyperlipidemic conditions, which can be used as a valuable neutraceutical application for the treatment of hyperlipidemia.</P>

The rationales of brain function development by ketone body
Yi-Sub Kwak 한국운동재활학회 2018 한국운동재활학회 학술대회 Vol.2018 No.10
Brain development is a complex process, and stimuli during this development period may modulate the functional maturation of the brain. It has been shown that environmental stimuli, such as physical activity habits, have a beneficial effect on brain development. Many human and animal studies have shown that environmental stimuli, such as physical activity habits, have a beneficial effect on brain development. Exercise has many functions not only in the developmental period of the brain but also in adulthood. Exercise is known to have many beneficial effects on brain function and energy metabolism. In the present study, we discussed on two main topics: “exercise and BDNF” and “exercise and energy restriction”. Endurance exercise and prolonged fasting state are known to improve brain function including cognition. The exact mechanisms of exercise on improving brain function are still unknown. However, it can be considered that energy restriction and stressful challenge induced by long-lasting physical exercise might cause direct effect on brain function. Up-regulation of brain-derived neurotrophic factor (BDNF) and ketone body caused by exercise might be considered as the mechanism of exercise on brain function. It is well known that long-term endurance exercise and fasting state improve brain function. Although the precise mechanisms for brain function improvement have not yet been elucidated, ketone body and BDNF have been suggested as the main substances of this action.

The Review of Environment, Food and Exercise on Allergy Anaphylaxis
Yi-Sub Kwak(곽이섭),Young-Ho Baek(백영호),Seung-Hyun Kim(김승현),Young-Il Kim(김영일),Byung-In Yoo(유병민) 한국생명과학회 2010 생명과학회지 Vol.20 No.1
규칙적인 운동이 면역력 증가에 도움을 주는 것이 일반적인 사실이지만 차고 건조한 환경에서의 격렬한 운동은 호흡기 질환의 일종인 운동 유발성 천식과 운동 유발성 알레르기 질환을 야기하고, 상기도 감염 등을 유발하기도 한다. 이는 수행되는 운동의 종류나 방법 등에 따라서 다르게 나타나며 운동 수행의 경험과 운동 환경 등에 따라서 상이하게 나타난다. 따라서 운동하는 환경이 야외에서 이루어지며 오존이나 먼지 등을 많이 접하면서 수행되는 운동과 동계 스포츠인 스키, 스노우보드, 스케이트 및 아이스하키와 같은 운동 수행으로 운동 시 폐가 차갑고 건조한 공기에 장시간 노출됨에 따라 운동 유발성 천식과 운동유발성 알레르기 반응이 초래된다. 이러한 반응은 음식 알레르기와도 함께 나타나는데, 음식 알레르기가 있는 사람은 운동 시 더욱 알레르기 반응이 증가하게 되고, 음식 알레르기가 나타나지 않은 사람도 특정 음식 섭취 후 격렬한 운동 시 운동 유발성 알레르기가 나타나기도 한다. 이는 일반적으로 소화된 음식물이 장으로 지나갈 때, 혈액의 IgA가 덜 소화된 단백질을 혈액으로 들어오는 것을 방어해 주지만, 결렬한 운동이나 스트레스 상황에서는 IgA가 감소하게 되고, 이러한 상황에서 음식 유발성 알레르기 질환이 나타나게 되는데, 운동 시 이러한 반응이 더욱 심화되며 운동 유발성 알레르기 아나플락시스로 나타나기도 한다. 운동 유발성 알레르기 질환은 운동의 방법, 종류 및 수행되는 운동시간 등에 따라 깊은 관련이 있으며, 임상적인 징후로는 심한 기침, 가슴의 답답함, 호흡 곤란, 쌕쌕거림의 현상, 피부두드러기 및 혈관부종, 심할 경우 혈관파괴 등의 현상이 나타나고, 돌연사의 원인이 되기도 한다. 격렬한 운동은 과 호흡을 유발시키고, 이로 인해 폐의 비만세포가 증가하게 되며, 증가된 비만세포에서 나오는 히스타민이 알레르기 반응을 유발한다. 운동 유발성 두드러기나 아나필락시스 진단에 있어 가장 중요한 사항은 가족력과 병력에 대한 사항이며, 이외에도 메타콜린 피부 반응검사 등이 있다. 치료는 일상생활에서 활동의 수준과 범위를 수정하는 하는 것이 핵심이며, 이를 위해서는 전문가를 통한 환자 교육이 매우 중요하며, 식후에는 시간을 두고 운동해야 한다. 그리고 운동전 알레르기를 유발하는 음식물의 섭취를 제한해야 한다. 본 연구자는 운동 알레르기와 관련된 인자를 크게 운동 시의 환경과 음식물로 구분하고, 여러 문헌을 고찰하여, 운동 시 일어날 수 있는 알레르기 반응을 미연에 방지하고, 운동을 수행하는 엘리트 운동선수 및 동호인, 운동을 지도하는 지도자, 스포츠 산업에 종사하는 사람들에게 기초자료를 제공하고자 한다. Exercise-induced anaphylaxis (EIA) is a physical allergy, sometimes severe, triggered by exertion following specific food intake. It was defined for the first time in 1980. EIA is associated with different kinds of exercise. The clinical manifestations progress from itching, erythema and urticaria to some combination of cutaneous angioedema and vascular collapse. Mast cell participation in the pathogenesis of this syndrome has been proved by the findings of an elevated serum histamine level during exhaustive exercise. As predisposing factors of EIA, a specific or even nonspecific sensitivity to food has been reported. Food-dependent exercise-induced anaphylaxis (FDEIA) is a distinct form of food allergy induced by physical exercise. It is typified by the onset of anaphylaxis during exercise which was preceded by the ingestion of the causal food allergens. The diagnosis of FDEIA is heavily dependent on clinical history. Allergy tests may need to be performed using a broad panel of food and food additives. As with food allergies, FDEIA diagnosis is based on interview, biological test and skin test. Prophylaxis aims to prevent a recurrence; the patient should be given an emergency kit to deal with any recurrent episodes. After the food allergen has been identified, it should be avoided for at least 4 to 5 hours before any exercise. Two cases of EIA are presented (EIA to circumstances; FDEIA) in this paper, The diagnosis, pathophysiology and therapy of FDEIA are also reviewed.
