The objective of this paper is to verify clinical effects of Lyu's Soyosan(柳氏逍遙散) and Lyu's Kwipithang(柳氏歸脾湯). They were prescribed to the enperimental student group suffering from mental stress and annoyed by psychological instability. From the biochemical examination before and after medication, we measure the amount of hormonal variation in thyroid hormone(TSH, $T_4$) and adrenocortical hormone(ACTH, cortisol) The results are as follows. 1. The average of self-rating anxiety scale(SAS) in test group is $41.00\;{\pm}\;7.84$. This value is statistical significant and higher than one of normal person(age 20-39). The average of a global assesment of recent stress(GARS) scale is $28.62\;{\pm}9.00$. There is statistical correlation coefficient between SAS and GARS (p < 0.001). 2. Both Lyu's Soyosan(柳氏逍遙散) and Lyu.s Kwipithang (柳氏歸脾湯) groups show statistically significant reduction of total cholesterol and triglyceride level in serum lipid after ten day medication. 3. It is observed that Lyu's Soyisan(柳氏逍遙散) and Luy's Kwipithang (柳氏歸脾湯) groups have increasing tendency of TSH. The statistically significant reduction of $T_4$ was found in two groups after ten day medicaton. 4. It is observed that Lyu's Soyosan(柳氏逍遙散) and Lyu's kwipithang (柳氏歸脾湯) group have statistically significant reduction of serum cortisol level after ten day medication, Both groups have statistically significant reduction of plasma ACTH level after twenty day medication. From these results, it is verified that both Lyu's Soyosan(柳氏逍遙散) and Lyu's Kwipithang (柳氏歸脾湯) have anti-stress effects against psychological instability and mental stress. The Lyu's Soyosn(柳氏逍遙散) shows special effectiveness in depression of liver-energy(肝氣鬱結) and the Lyu's Kwipitang (柳氏歸脾湯) is also effective in deficiency heart-blood(心血不足).

이 연구의 목적은 신체활동이 마이오카인 발현에 미치는 영향을 보고자 문헌고찰을 하였다. 신체적인 활동은 제2형 당뇨, 심혈관질환, 대장암, 치매 및 우울증과 같은 질환을 예방하는 역할을 하고 있다. 그리고 마이오카인(myokine)은 운동 훈련에 의해 분비되는 호르몬으로 뇌성장이나 알츠하이머 같은 질환 예방에 도움을 준다. 운동수행과정에서 수축하는 근육으로부터 분비되는 항염증 마이오카인의 생성과 대사 조절에 필요한 분비 활성화가 건강증진에 중요한 요인으로 보고 있다. 인체 골격근에서 분비되는 마이오카인 가운데 IL-4, IL-6, IL-7, IL-8, IL-15 등은 근육비대(hypertrophy)와 세포(myogenesis) 및 혈관생성(angiogenesis) 등의 조절에 관여한다. IL-6는 AMPK 활성화로 인한 대사중 지방 산화를 촉진시키는 작용을 하고, IL-1Ra, IL-10 과 sTNF-R 는 염증성 싸이토카인 $TNF-{\alpha}$의 분비를 억제한다. IL-15는 저항 운동시 근수축을 통한 발현량이 증가하어 근육 성장의 중요 합성요인으로 작용한다. 한편 IL-7 및 IL-8도 신호 전달 수용체 C-X-C를 통해 혈관신생을 촉진시킨다.

We investigate the solar cycle variation of microwave and extreme ultraviolet (EUV) intensity in latitude to compare microwave polar brightening (MPB) with the EUV polar coronal hole (CH). For this study, we used the full-sun images observed in 17 GHz of the Nobeyama Radioheliograph from 1992 July to 2016 November and in two EUV channels of the Atmospheric Imaging Assembly (AIA) $193{\AA}$ and $171{\AA}$ on the Solar Dynamics Observatory (SDO) from 2011 January to 2016 November. As a result, we found that the polar intensity in EUV is anti-correlated with the polar intensity in microwave. Since the depression of EUV intensity in the pole is mostly owing to the CH appearance and continuation there, the anti-correlation in the intensity implies the intimate association between the polar CH and the MPB. Considering the report of Gopalswamy et al. (1999) that the enhanced microwave brightness in the CH is seen above the enhanced photospheric magnetic field, we suggest that the pole area during the solar minimum has a stronger magnetic field than the quiet sun level and such a strong field in the pole results in the formation of the polar CH. The emission mechanism of the MPB and the physical link with the polar CH are not still fully understood. It is necessary to investigate the MPB using high resolution microwave imaging data, which can be obtained by the high performance large-array radio observatories such as the ALMA project.

The water extract of Gamidaebo-Tang depressed the lethal toxicity of cis-platin$(45{\mu}M/kg,\;s.c.)$, and mitomycin C (6mg/kg, s.c.). Significant depression of renal toxicity(indicated by an increased blood urea nitrogen value and creatinine value) of cis-platin $(35{\mu}M/kg)\;s.c.)$, was observed in mice treated with Gamidaebo-Tang. In rats treated with mitomycin C and Gamidaebo-Tang, the increased LDH activity and reduced total protein and albumin contents by mitomycin C were significantly depressed. The number of WBC was significantly increased in rats treated with mitomycin C but in the rats treated with mitomycin C and Gamidaebo-Tang, the number of WBC was increased and the hematocrit value and the number of RBC and Hgb were significantly increased in the dose-dependent manner. Therefore, bone marrow toxicity of mitomycin C in the rats treated with Gamidaebo-Tang was depressed. In the end, alleviative effects of the side actions of cis-platin and mitomycin C were acknowledged by combined usage of Gamidaebo-Tang and these anti-neoplastic drugs.

Silibinin, a natural flavonoid antioxidant isolated from extracts of the milk thistle herb, has recently been identified as having anti-hepatotoxic and anticancer properties. In this paper, we investigated the effects of silibinin on behavior and neuroplasticity in mice subjected to chronic unpredictable mild stress (CUMS). After 5 consecutive weeks of CUMS, the mice were treated with silibinin (100 mg/kg, 200 mg/kg and 400 mg/kg by oral gavage) for 3 consecutive weeks. The results showed that silibinin administration significantly alleviated the CUMS-induced depressive-like behavior, including the total number of squares crossed and the frequency of rearing in the open field test, the immobility time in the tail suspension test and the forced swimming test. Furthermore, silibinin treatment increased the levels of brain-derived neurotrophic factor (BDNF), serotonin (5-HT) and norepinephrine (NE) in the prefrontal cortex and hippocampus. Our study provides new insight into the protective effects of silibinin on the depressive status of CUMS mice, specifically by improving neuroplasticity and neurotransmission.

Breastfeeding is highly recommended due to its benefits for both the infant and mother; however, most mothers predominantly use formula feed. Breastfeeding affords protection against a wide variety of medical conditions that may emerge at different time points over the lifespan, including hospital admissions for respiratory infections and neonatal fever, offspring childhood obesity, and cancer as well as cardiovascular disease, hyperlipidemia, hypertension, and diabetes. Moreover, breastfeeding is expected to decrease the risk of adolescent depression and other psychopathologies. It is also important for the development of the gut, gut-brain axis, and immune system, and night-time breast milk is likely to have higher antioxidant, anti-inflammatory, and immune regulatory effects due to the impact of breast milk melatonin on the infant's developing microbiome and gut permeability. Melatonin can be added to a night-time-specific formula feed; however, it is not included in the Korean Food Additive Codex.

Five puppies, 14 days old in the same litter showed acute symptoms such as painful crying, anorexia, abdominal pain and depression with fatal terminations. Necropsy of a puppy revealed hemorrhagic and necrotic foci in the lungs and kidney. The histological lesions were characterized with fibro-necrotizing foci in the lungs, nonsuppurative encephalitis and intranuclear inclusions of liver cells. A cytopathogenic agent was isolated from the thoracic fluid of a dead puppy by cell culture with primary dog kidney cells. The puppies inoculated with the field isolate showed the same clinical signs and lesions as those of the spontaneous cases. Viral particles were observed in suspension of the isolated agent by electron microscopy. The primary dog kidney cells infected with the field isolate showed fluorescent foci against anti-CHV monoclonal antibody after FA stain. On these findings of the disease it was diagnosed as CHV infection. The report signifies the first description of an epizootic of CHV infection in Korea.
