Objective; Antistress effect of Korean red ginseng (RG) on postmenopausal women with severe climacteric syndrome (CS) were evaluated from the viewpoint of traditional KAMPO-medicine and Western medicine. Methods; All patients with CS were treated with daily oral administration of 6g RG for 30 days. Nine patients with CS were evaluated with the use of diagnostic scores for KI-deficiency (deficiency of vital energy) and OKETSU (blood stagnation) syndrome from the viewpoint of KAMPa-medicine. In the same patients with CS, peripheral blood levels of $\beta$-endorphin and total plasminogen activator inhibitor-1 (t-PAI-1) were measured before and after treatment with RG. In another group, 12 patients with CS, psychological test using CMI, STAI and SDS were performed from the viewpoint of Western medicine. Stress related hormones, such as ACTH, cortisol and DHEA-S in those 12 patients with CS were also measured before and after treatment with RG. Results; KI-deficiency score and OKETSU score in patients with CS were significantly (p<0.001) higher than those in patients without CS. After treatment with RG, both scores were markedly (p<0.001) decreased compared to before treatment with RG. ${\beta}-endorphin$ levels in patients with CS were significantly (p<0.05) higher than those in patients without CS. Total PAI-I levels in patients with CS were increased before treatment with RG. No significant difference, however, were observed between patients with and without CS. After treatment with RG, both levels of ${\beta}-endorphin$ and total PAI-l in patients with CS were significantly (p<0.01 and p<0.05, respectively) decreased compared to before treatment with RG. CMI and STAI scores in patients with CS were significantly (p<0.05) higher than those in patients without CS. SDS scores in patients with CS were also markedly (p<0.001) higher than in those without CS. After treatment with RG, all scores decreased within normal range. DHEA-S levels in patients with CS were about a half of those without CS. Consequently, cortisol/DHEA-S (C/D) ratio was significantly (p<0.001) higher in patients with CS than in those without CS. Although the decreased DHEA-S levels were not restored to the levels in patients without CS, the C/D ratio decreased significantly (p<0.05) after treatment with RG. Conclusion; Reinforcement of vital energy and improvement of stagnant blood circulations by oral administration of RG were elucidated from the viewpoint of traditional KAMPO-medicine. From the viewpoint of Western medicine, effect of RG on postmenopausal women with CS seemed to be brought about in part by not only an improvement of psychoneuroendocrine dysfunctions but also an amelioration of blood coagulation systems.

The purpose of this study was to determine the effects of photoperiod and light intensity on milk production, milk composition, hormones levels and blood metabolites indices of Korean Holstein dairy cows in automatic milking system (AMS). A total of 24 Holstein dairy cows were selected and used to four subsequent treatments for the experimental periods of 60 days. The light programs consisted of (1) Control: the natural photoperiod with 14.2 h of the light period and 9.4 h of the dark period (below 10 Lux); (2) T1: 16 h of the long day photoperiod (LDPP) with 50 Lux of light; (3) T2: 16 h of LDPP with 100 Lux of light; and (4) T3: 16 h of LDPP with 200 Lux of light, respectively. Importantly, there was a significant difference in the thurl activity of dairy cows between the different light intensity programs (p < 0.05). Milk yield was higher in T1 and T2 (40.80 ± 1.71 and 39.90 ± 2.02 kg/d, respectively) than those of Control and T3 (32.18 ± 1.51 and 35.76 ± 2.80 kg/d, respectively) (p < 0.05), but DMI was lower in T1, T2, and T3 compared to Control (p < 0.05). Also, milk fat percentage, the contents of milk fat and total solids were higher in T2 than those in the others (p < 0.05). The average daily melatonin level in milk was high to T3 (28.20 ± 0.43 pg/mL), T2 (24.62 ± 0.32 pg/mL), T1 (19.78 ± 0.35 pg/mL), and Control (19.36 ± 0.45 pg/mL) in order (p < 0.05). Also, the cortisol levels in milk and blood were lower in treatment groups than in Control (p < 0.05). The results of this study showed that it will be effective to improve the milk yield and milk composition, and to reduce the stress of dairy cows when the light conditions regulate to extend the photoperiod to 16 h at a light emitting diode (LED) intensity of 100 Lux under the AMS in dairy farm.

BACKGROUND/OBJECTIVES: Premenstrual syndrome (PMS) is a disorder characterized by repeated emotional, behavioral, and physical symptoms before menstruation, and the exact cause and mechanism are uncertain. Hyperprolactinemia interferes with the normal production of estrogen and progesterone, leading to PMS symptoms. Thus, we judged that the inhibition of prolactin hypersecretion could mitigate PMS symptoms. MATERIALS/METHODS: Hordeum vulgare L. extract (HVE), Chrysanthemum zawadskii var. latilobum extract (CZE), and Lomens-P0 the mixture of these extracts were tested in subsequent experiments. The effect of extracts on prolactin secretion at the in vitro level was measured in GH3 cells. Nitric oxide and pro-inflammatory mediator expression were measured in RAW 264.7 cells to confirm the anti-inflammatory effect. Also, the hyperprolactinemic Institute for Cancer Research (ICR) mice model was used to measure extract effects on prolactin and hormone secretion and uterine inflammation. RESULTS: Anti-inflammatory effects of and prolactin secretion suppress by HVE and CZE were confirmed through in vitro experiments (P < 0.05). Treatment with Lomens-P0 inhibited prolactin secretion (P < 0.05) and restored normal sex hormone secretion in the hyperprolactinemia mice model. In addition, extracts significantly inhibited the expression of pro-inflammatory biomarkers, including interleukin-1𝛽, and -6, tumor necrosis factor-𝛼, inducible nitric oxide synthase, and cyclooxygenase-2 (P < 0.01). We used high-performance liquid chromatography analyses to identify tricin and chlorogenic acid as the respective components of HVE and CZE that inhibit prolactin secretion. The Lomens-P0, which includes tricin and chlorogenic acid, is expected to be effective in improving PMS symptoms in the human body. CONCLUSIONS: The Lomens-P0 suppressed the prolactin secretion in hyperprolactinemia mice, normalized the sex hormone imbalance, and significantly suppressed the expression of inflammatory markers in uterine tissue. This study suggests that Lomens-P0 may have the potential to prevent or remedy materials to PMS symptoms.

Purpose: Triple-positive breast cancer is defined by estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2) positivity. Several systemic breast cancer therapies target hormonal and HER2 responsiveness. We compared clinical outcomes of triple-positive disease with those of HER2-enriched and luminal HER2-negative disease and investigated the clinical efficacy of anti-HER2 therapy for triple-positive disease. Methods: We retrospectively compared overall and recurrence-free survival among cases included in the Korean Breast Cancer Society (KBCS) and Seoul St. Mary's Hospital breast cancer registries and the therapeutic efficacy of trastuzumab for triple-positive and HER2-enriched cases. Results: KBCS registry data (2006-2010; median follow-up, 76 months) indicated that patients with triple-positive breast cancer had intermediate survival between those with luminal A and HER2-enriched subtypes (p<0.001). Trastuzumab did not improve overall survival among patients with triple-positive breast cancer (p=0.899) in contrast to the HER2-enriched subtype (p=0.018). Seoul St. Mary's Hospital registry data indicated similar recurrence-free survival outcomes (p<0.001) and a lack of improvement with trastuzumab among patients with triple-positive breast cancer (median follow-up, 33 months; p=0.800). Multivariate analysis revealed that patients with triple-positive breast cancer had better overall survival than those with HER2-enriched disease and similar survival as those with the luminal A subtype (triple-positive: hazard ratio, 1.258, p=0.118; HER2-enriched: hazard ratio, 2.377, p<0.001). Conclusion: Our findings showed that anti-HER2 therapy was less beneficial for treatment of triple-positive breast cancer than for HER2-enriched subtypes of breast cancer, and the triple-positive subtype had a distinct prognosis.

천남성과에 속한 칼라는 생육 조건에 따라 두 종류로 구분이 가능한데 그 중 꽃 모양과 화색이 다양한 유색 칼라는 절화로서 인기가 매우 높다. 그러나 유색 칼라는 자연 번식률이 매우 낮고 개화구근을 얻기 까지 오랜 시간이 소요되어 우량 품종의 대량 번식 체계 확립이 시급하다. 따라서 본 연구에서는 칼라 기내 식물체의 생육을 향상시키고자 다양한 식물 성장 호르몬을 처리하여 실험을 진행하였다. 뿌리 발생은 기본 MS 배지에서 81.5 %로 가장 높았고 신초 및 다신초 발생률은 BA 2.0 mg/L와 IBA 1.0 mg/L 혼용 처리구에서 100.0 %와 36.4 %로 가장 높았다. 또한 생체중에서는 BA 2.0 mg/L 단일 처리구에서 11.2배가 증가하여 모든 처리구중 가장 높은 증가율을 보였다. Auxin과 cytokinin 혼용 처리 실험은 이전 연구에서도 많이 이용되고 있고 칼라 식물 생장에도 긍정적인 효과를 줌으로써 미소대량증식체계 확립에 도움을 줄 것이라고 판단된다.

충청남도 부여군 석성면 양송이 재배 농가에서 양송이 수확 후 배지로부터 토양을 채취하여 auxin(IAA) 생성능이 뛰어난 세균 Yangsong-1 균주를 분리하였다. TLC 및 HPLC 분석을 통해 분리균이 생성한 IAA 농도를 확인한 결과, 0.2% L-tryptophan를 함유한 pH 7.0의 R2A broth 배지에 $35^{\circ}C$, 48시간 배양 시 최대 생성농도는 $126.33mg\;L^{-1}$이었다. 생리적 특성 및 계통학적특성 분석을 통해 분리균은 Gram 음성 간균인 Arthrobacter enclensis Yangsong-1로 동정되었다. 배양조건별 IAA의 생산능 비교 시, IAA 농도의 증가가 배양액의 pH 산성화에 기인함으로서 IAA 생성량과 pH 변화에는 부의 상관성이 있는 것으로 관측되었다. IAA 생성을 위한 전구물질로 알려진 L-tryptophan의 첨가효과는 0.2% 첨가 시 균 생육 및 IAA 생성량이 최대이었으며, 0.4% 이상 고농도 첨가 배지에서는 오히려 IAA의 생성이 저해되었다. 또한 분리균에 의한 식물생육촉진효과를 조사하기 위하여 수경재배 및 pot 재배를 통한 녹두발근 생검법과 상추발근 생검법을 수행한 결과, A. enclensis Yangsong-1의 배양액 접종 시 녹두발근 생검법에서는 대조구에 비해 발근수와 뿌리길이에서 약 1.5배의 뿌리신장효과를 보였고, 상추발근 생검법에서는 대조구에 비해 뿌리길이와 무게에서 약 1.9배의 뿌리신장효과를 보였다.
