This study was conducted to investigate the effects of black raspberry wine which was administered per os on estrogen levels in Splague-Dawley(SD) rats. Black raspberry wine containing 13% alcohol(v/v) was prepared from ripe fruits of Rubus coreanus fermented with Saccharomyces cervisiae. The rats were divided into 2 groups(A and B): The group A received black raspberry wine and the group B received saline for 7 weeks. All animals were bi weekly monitored for estrogen levels by radioimmunoassay using $125^I$ labeled anti-estrogen monospecific antibody. There was a significant(2.02 fold) increase in estrogen levels in the group A with a peak at the 7th week post administration of black raspberry wine. There was no significant change in estrogen levels of the rats in the group B. These data point to uncharacterized phytoestrogenic bioactivity of black raspberry wine that appears to be a useful phytoestrogenic herbal remedy for human health.

Objectives: The purpose of this study was to investigate the effects of modified fasting therapy on the changes of body compositions. Methods: We analyzed the medical records of 33 patients, who carried out modified fasting therapy at Dunsan Korean Medicine Hospital of Daejeon University from January 1st, 2011 to December 30th, 2015. They went through reducing food intakes period (7 days), fasting period (14 days) and refeeding period (14 days). Body compositions (weight, body mass index, skeletal muscle mass, percent body fat, basal metabolic rate, waist-hip ratio, visceral fat area) were reviewed at each state. And then the data was analyzed. Results: The body composition values (weight, body mass index [BMI], skeletal muscle mass, percent body fat, basal metabolic rate, waist-hip ratio, visceral fat area) decreased during the fasting therapy period, as a whole. The weight, BMI, percent body fat and visceral fat area decreased during the reducing food intakes period, the fasting period and the refeeding period. The skeletal muscle mass and basal metabolic rate significantly decreased during the reducing food intakes period and the fasting period, and insignificantly increased during the refeeding period. Conclusions: Results from this investigation showed that modified fasting therapy using fermented herbal medicine have positive effects on changes of body compositions.

Although antioxidant activities of Korean traditional fermented foods were reported by many researchers, study on antioxidant activity of microorganism originated from Korean traditional fermented foods was little. Therefore, we improved condition for antioxidant production by a bacterium isolated from home-made Chungkookjang. We selected a bacterial strain, which showed the highest antioxidative activity, from Chungkookjang and then named GJ. The selected GJ strain was identified as Bacillus methylotrophicus by alignment data of 16S rRNA gene nucleotide sequences. Improved medium compositions for DPPH radical scavenging activity were 0.25% sucrose, 1% peptone, 0.01% $MgSO_4{\cdot}7H_2O$ and initial pH 6.5, respectively. Optimal culture conditions were $30^{\circ}C$, 200 rpm and 4% inoculum volume, respectively. In improved conditions, DPPH radical scavenging activity of GJ reached to 91% in a short time. The strain GJ also possessed ACE inhibition and other antioxidative activities; ACE inhibition activity (49.4%), ABTS radical scavenging activity (99.8%), metal chelating activity (67.9%), SOD-like activity (36.5%) and reducing power ($A_{700}$ = 5.982) were observed, respectively. Therefore, our results suggest that B. methylotrophicus GJ strain may be potential candidate for functional foods, cosmetic products for anti-aging and medicine for diseases caused by oxidative stress.

Scutellaria baicalensis (SB) has widely used in the treatment for various brain diseases in the field of Oriental medicine. Biofermantation of SB can make major chemical constituents of SB to pass blood-brain barrier easily and to have more potent anti-oxidant ability. There is a little information about the contribution of fermented SB (FSB) to the formation or maintenance of the neural plasticity in the hippocampus. The purpose of this study was to evaluate effects of FSB extract on hydrogen peroxide (H₂O₂) - induced impairments of the induction and maintenance of long-term potentiation (LTP), an electrophysiological marker for the neural plasticity in the hippocampus. From hippocampal slices of rats, the field excitatory postsynaptic potentials (fEPSPs) were evoked by the electrical stimulation to the Schaffer collaterals - commissural fibers in the CA1 areas and LTP by theta-burst stimulation by using 64 - channels in vitro multi-extracellular recording system. In order to induce oxidative stress to hippocampal slices two different concentrations (200, 400 μM) of H₂O₂ were given to the perfused aCSF before and after the LTP induction, respectively. The ethanol extract of FBS with concentration of 25 ㎍/ml, 50 ㎍/ml was diluted in perfused aCSF that had 200 μM H₂O₂, respectively. Oxidative stress by the treatment of H₂O₂ resulted in decrease of the induction rate of LTP in the CA1 area with a dose - dependent manner. However, the ethanol extract of FSB prevented the reduction of the induction rate of LTP caused by H₂O₂ - induced oxidative stress with a dose - dependent manner. These results may support a potential application of FSB to ameliorate impairments of hippocampal dependent neural plasticity or memory caused by oxidative stress.

저 용량 Streptozotocin(STZ)으로 유도한 제l형 당뇨 모델 생쥐에서 건조 구아바 잎과 발효 구아바 잎 에탄올 추출물의 혈당에 미치는 영향을 비교하였다. STZ로 유도된 쥐에서 발효 구아바 잎 추출물(500 mg/kg/day)은 투여 4주후에도 공복 혈당이 유의적으로 감소하였으며 내당능 장애도 개선되었음을 보여 주었다. 한편 건조 구아바 잎 추출물은 투여 후 2주 동안 공복 혈당이 낮게 나타났으며 내당능 장애도 개선되었지만 3주후부터 고혈당으로 약화되었다. 각 실험군에서 적출한 췌장 조직과 인슐린의 면역 조직 화학 분석 결과, 발효 구아바 잎 추출물은 STZ로 유도된 췌장섬 세포의 손상을 억제하는 것이 관찰되었으나 건조 구아바 잎 추출물은 베타 세포의 손상에 영향을 주지 못하였다. 본 연구 결과는 STZ로 유도된 당뇨 모델 생쥐에서 발효 구아바 잎 추출물이 췌장 베타 세포의 손상을 보호함으로서 혈당 개선 효과를 나타냄을 보여준다.

호장근 발효 추출물을 대상으로 피부노화 억제활성을 살펴보고자 발효 전후의 호장근 추출물을 대상으로 피부 홍반도, 유수분 함량, 형태학 조직병리학적 검사, GSH, TBARS 그리고 XO, SOD, CAT 등의 항산화 효소활성을 측정하였다. 피부 홍반도에 있어서는 대조군에 비해 호장근 발효 추출물 처리군에서 뛰어난 홍반 감소 효과를 확인할 수 있었으며, 유수분 함량에 있어서도 FR-1000군이 유분함량은 $21.75{\pm}0.72$, 수분함량은 $55.13{\pm}1.07$로 CO군에 비해 유의하게 높은 함량을 보였다. 또한 형태학적으로는 FR을 처리한 실험군에서 피부의 주름이 현저하게 감소되었으며, 조직병리학적 검사에서도 표피 및 진피의 화농과 염증의 치료에 상당한 효과가 있음을 확인하였다. 또한 호장근 발효 추출물의 농도가 증가할수록 GSH는 증가하고 TBARS와 XO의 활성은 감소하였으며, 항산화 효소인 SOD, CAT 활성은 농도 의존적으로 증가함을 확인할 수 있었다. 이러한 결과들을 종합하여 볼 때 UVB 조사로 노화가 유발된 hairless mouse에서 호장근 발효 추출물의 도포가 노화된 피부에 염증반응을 약화시키며 유수분 함량을 증가시켜 피부장벽의 손상을 방지하며, 항산화 효소 및 resveratrol과 같은 항산화 물질을 증가시켜 항노화 기능성을 가지는 것으로 판단된다. 이로써 호장근 발효 추출물은 피부노화 예방 및 기능성 화장품 원료로서의 사용 가능성을 제시하는 바이다.
