Atypical hemolytic uremic syndrome (HUS) in adults is a life-threatening disorder characterized by microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure, which is not related to Escherichia coli. This disease occurs under the condition of certain stresses, including pregnancy related disease like as preeclampsia, placental abruption, and amniotic fluid embolism. Heparin and plasma exchange has proven to be an effective treatment for HUS and it has decreased the mortality of this illness. We experienced a case of 34 weeks` pregnant woman with preeclampsia who presented with hematuria, oliguria, hemolytic anemia and thrombocytopenia. We performed emergency cesarean section due to fetal distress. After operation, she was treated with transfusion of packed red blood cell, parenteral albumin, and anticoagulant. After seven days from the operation, the sign of hematuria disappeared and her renal function partially recovered. We describe this case with a brief review of the literature.

사람의 피부는 자외선, 오염된 공기, 화학제품 등 환경에 끊임없이 노출된다. 특히 자외선은 피부에 다양한 형태로 영향을 주어 주름, 잔주름, 피부거침, 피부건조와 같은 현상을 발생시켜 피부노화를 유발시킨다. 본 연구에서는 전 세계적으로 향나무과의 일종인 다년생 수목인 노간주나무(Juniperus rigida Sieb.) 추출물의 주름개선 효과에 대하여 검증하였다. 주름개선 효과 측정으로 elastase 저해활성을 측정한 결과 노간주나무 열수 추출물 1,000 μg/ml에서 10% 이하의 낮은 저해활성을 나타낸 반면에 노간주나무 에탄올 추출물의 1,000 μg/ml에서 68.5%의 저해활성을 나타내었으며, collagenase 저해활성을 측정한 결과 1,000 μg/ml에서 열수 및 에탄올 추출물은 44.9%, 97.2%로 에탄올 추출물의 경우 ascorbic acid (99.6%)와 유사한 효과로 높은 저해활성을 나타내었다. 또한 섬유아 세포를 이용한 collagen 생합성량을 측정한 결과 노간주나무 에탄올 추출물 50 μg/ml에서 151.52%의 생합성 촉진 효과를 나타내어 노간주나무 에탄올 추출물의 주름개선 효과가 우수하다는 것을 확인할 수 있었다. UVA에 의해 발현이 증가되는 MMP-1에 노간주나무 에탄올 추출물이 미치는 영향을 알아본 결과 노간주나무 에탄올 추출물은 100 μg/ml에서 67.1%의 MMP-1 발현 저해효과를 나타내었다. 노간 주나무 에탄올 추출물의 MMP-1의 단백질 및 mRNA의 발현은 50 μg/ml의 농도에서 각각 35%, 39%의 저해율을 나타냄에 따라 노간주나무 에탄올 추출물은 collagen을 분해하는 효소인 MMP-1의 발현을 억제하고 광노화에 의한 주름생성 억제 활성을 보이는 것을 확인하였다. Human skin is constantly exposed to environmental conditions such as UV rays, polluted air, and chemical products. UV rays, in particular, affect skin in many ways causing wrinkles, fine wrinkles, rough skin, and xeroderma through a skin aging process. The purpose of this study was to investigate the anti-wrinkling effect of Juniperus rigida Sieb., derived from a common cedar tree found the world over. Measuring the elastase to investigate wrinkling efficacy, it was shown that at a concentration level of 1,000 μg/ml of the two extracts, the water extract exhibited a lower than 10% inhibition activity, while the ethanol extract exhibited a 68.5% inhibition activity. Collagenase inhibition activity in the water extract and ethanol extract were 44.9% in the former and 97.2% in the latter extract, which in the case of the ethanol extract, is similar to ascorbic acid (99.6%). Moreover, measuring the biosynthesis of collagen by fibroblast, a concentration level of 50 μg/ml of ethanol extract produced 151.52% of biosynthetic promotion, proving that the ethanol extract acts as a superb anti-wrinkling agent. The result of an investigation conducted on the influence of the ethanol extract on MMP-1 caused by UVA showed that at a concentration level of 100 μg/ml of the ethanol extract of J. rigida Sieb a 67.1% inhibition activity was noted. At a concentration level of 50 μg/ml of the ethanol extract of J. rigida Sieb a 35% and 39% inhibition ratio to MMP-1 protein and mRNA were observed respectively, thereby restraining the appearance of the collagen breakdown enzyme MMP-1 and wrinkle creation by skin photo-aging.

사람의 피부는 자외선, 오염된 공기, 화학제품 등 환경에 끊임없이 노출된다. 특히 자외선은 피부에 다양한 형태로 영향을 주어 주름, 잔주름, 피부거침, 피부건조와 같은 현상을 발생시켜 피부노화를 유발시킨다. 미백효과를 확인하기 위하여 tyrosinase 저해활성을 측정한 결과 열수 추출물에서 49.4%, 에탄올 추출물에서 80.0%의 효과를 나타내어 열수 추출물에 비해 에탄올 추출물의 효과가 높게 나타났으며, 노간주나무 에탄올 추출물이 B16F10 흑세포종에 대하여 멜라닌 색소 생성 억제 및 tyrosinase, MITF, TRP-1, TRP-2의 억제 효과를 가지고 있는 것을 확인하였다. 이와 같은 결과로 미루어 보아 열수 추출물보다 에탄올 추출물이 더 높은 효과를 나타냄을 확인할 수 있었으며, 노간주나무 추출물의 미백효과를 이용하여 기능성 화장품 소재로서의 가능성을 확인할 수 있었다. Human skin is constantly exposed to ultraviolet (UV) radiation, polluted air, and chemical products. UV rays, in particular, will affect the skin in a variety of ways, including causing wrinkles, fine lines, rough skin, and xeroderma, thereby resulting in skin aging. This study aimed to investigate the whitening effects of Juniperus rigida Sieb., which is a cedar tree that is found throughout the world. The whitening efficacy that was measured by tyrosinase inhibition revealed 49.4% efficacy in water extract and 80.0% efficacy in ethanol extract. Among the B16F10 black cells, the effect of the ethanol extract was higher than the effect of the water extract in the restrain creation of melanin pigment, tyrosinase, microphthalmia-associated transcription factor (MITF), tyrosinase related protein-1 (TRP-1), and tyrosinase related protein-2 (TRP-2). Thus, the results of these studies demonstrated that the ethanol extract had greater efficacy than the water extract and Juniperus rigida Sieb. Ethanol extracts could be utilized as materials for functional cosmetics, such as whitening products.

본 연구는 진범의 in-vitro 생리활성과 진범 향이 신경생리학적으로 뇌파에 미치는 영향을 비교 분석하였다. 그 결과 진범 향 및 재조합 향 흡입 시 흡입 전에 비해 뇌파지표 absolute alpha power spectrum (AA)와 absolute theta power spectrum (AT)가 유의미하게 감소하였으며(p<0.05), 진범과 진범 재조합 향 흡입 시 출현한 파형의 유발 부위가 각각 조금씩 다른 양상을 나타내기는 하였지만, 동일하게 alpha와 theta파가 나타났으며, 증가율 역시 향 흡입 시 감소하는 동일 양상을 나타내어 뇌에 각성효과를 일으킨 것으로 판단된다. 진범의 생리활성검증 결과 수렴효과를 제외한 DPPH, collagenase, nitric oxide 저해활성 검증에서 진범 에탄올 추출물의 활성이 열수 추출물에 비해 우수하였으며, 특히 collagenase저해활성에서 진범 에탄올 추출물 500 ppm에서 80%의 저해활성을 나타내었으며, 또한 nitric oxide 저해활성에서 진범 열수 및 에탄올 추출물 100 ppm에서 50% 이상의 NO저해활성을 나타내었다. 이러한 결과로부터 진범은 화장품 및 향료 개발의 천연소재로 사용이 가능할 것으로 판단된다. This study analyzed the in vitro physiological activity of Aconitum pseudolaeve var erectum Nakai (AP) and its effect on perfume on an electroencephalogram (EEG). The results indicated that the absolute alpha power spectrum (AA) and the absolute theta power spectrum (AT) decreased significantly during more than before the inhalation of the AP perfume and its reconstruction perfume. Although there were a little different pattern in the induced part of the wave generated by the inhalation of the AP perfume and its reconstruction perfume, alpha- and theta- were shown equally. In addition, there was the same pattern in which the rate of increase reduced. The results suggest that the perfume of the AP and its reconstruction perfume have a stimulating effect on the brain. In terms of the physiological activity of AP, the activity of AP ethanol extract was significantly higher than that of water extract in DPPH, collagenase, and nitric oxide, except for an astringent effect. The AP ethanol extract was about 80% at 500 ppm in collagenase inhibition activity. In addition, the AP water and ethanol extracts were 50% at 100 ppm in the NO inhibition activity. Based on these results, we conclude that this natural substance could be used in cosmetics and in the development of perfumes.

The physico-chemical properties of broccoli sprouts cultivated in a plant factory system with different lighting conditions were investigated. We reported that there were significant differences among the chemical and nutritional properties of the broccoli sprouts grown under different light sources. Two kinds of sugars (glucose and fructose) were detected in the plants. The amount of glucose was 2.94~3.12% and that of fructose was 1.54~2.04 %. Total chlorophyll was 1,157±0.004 mg% and chlorophyll-a 777±0.01 mg%. All over the test materials, 2 kinds of organic acids (citric acid and malic acid) were detected. The level of citric acid was 908~1,136 mg% and its highest level was under the (Blue LED) light source. The level of malic acid was 514~834 mg% and its highest level was under the (Red LED) light source. Seven different minerals were also analyzed. The amount of K was 518 mg% and its amount was significantly higher than that of Mg or Na. There were also negligible amounts of Zn, Fe and Cu. The amounts of vitamin A, C and E under the Red LED were, 860.62±0.02 μgRE, 134.570±0.14 mg% and 1.44±0.1 IU. The amounts under the Blue LED were, 432.48±0.05 μgRE, 137.05±0.1 mg% and 1.11±0.12 IU. The amounts under both Red and Blue LEDs were, 667.33±0.11 μgRE, 118.50±0.09 mg% and 1.47±0.1 IU. And finally, the amounts under a White LED were, 640.25±0.08 μgRE, 119.87±0.07 mg% and 1.31±0.15 IU. In this study, significant changes were shown in the chemical and nutritional properties of the broccoli sprouts. These findings indicate that LED light sources stimulated germination of the plants.
