Propolis possesses antimicrobial, anti-inflammatory, anaesthetic and immunostimulating activities. The aim of this study was to evaluated chemical composition and in vitro anti-Helicobacter pylori activity of eight propolis ethanolic extracts form different region in Korea. The chemical composition of eight Korean propolis was investicated by absorption spectrophotomety and UHPLC. Total penolic and total flavonoids content ranged between $21{\pm}1.5$ and $31{\pm}1.8$ gallic acid g/100 g and $7.2{\pm}0.9$ and $24.4{\pm}1.9$ quercetin g/100 g, respectively. The p-coumaric acid as standard components content ranged between $0.29{\pm}0.00$ and $2.34{\pm}0.02mg/g$ using UHPLC. Cinnamic acid content between $0.43{\pm}0.00$ and $1.33{\pm}0.01mg/g$. 80% ethanolic extract of propolis against H. pylori was evaluated by using the disc diffusion method. Ethanol was used as a control. Mean diameters of H. pylori growth inhibition using $10{\mu}g/mL$, $50{\mu}g/mL$ or $100{\mu}g/mL$ ethanol propolis per disc were 0, ranging from 0.9 to 2.1 mm and from 1.9 to 3.5 mm, respectively. In conclusion, variation in the chemical composition of Korean propolis were mainly due to the difference in the preferred regional plants visited by honeybees. Also Korean propolis possesses considerable antibacterial activity against H. pylori. There was not confirmed a correlation between the chemical composion contens and anti-H. pylori effect. The potential of propolis in the prevention or treatment of H. pylori infection is worth further extensive evaluation.

호박벌 일벌독의 성분과 생리활성을 규명하기 위하여 단백질 성분분석과 암세포 생육 저해 효능, 항균력을 검토하였다. 이차원단백질 분석을 통해 호박별의 일벌독은 63개의 단백질이 존재하는 것으로 확인되었으며, 가장 많은 함량을 보이는 3개의 단백질을 염기서열 분석하였다. 그러나 이들 성분은 아직 밝혀지지 않은 성분으로 판단되었다. 호박벌 일벌독의 암세포 (간암; Hep3B, 폐암; A549, 유방암; BT-20, 위암; AGS) 에 대한 생육 저해능은 시료 농도가 증가함에 따라 증가하는 경향을 보이며 100ng/ml에서 간암세포 (Hep3B) 에 대한 생육 저해능이 55%로 가장 높았다. 항균활성에 E. faecium 과 S. sonnei에 대하여 최소발육억제농도와 최소살균농도 모두 각각 0.256ug/ml 로 강한 항균활성을 나타내었으며, 그 외의 피검균에 대해서도 비교적 높은 활성을 보였다. 이상의 결과로부터 호박벌 일벌독의 성분은 다른 벌의 독성분과는 차이를 보이며, 그 생리활성에 있어 약리학적 이용이 가능할 것으로 판단되었다. Pure Bombus ignitus venom samples were submitted to two-dimensional gel electrophoresis. A total of 64 excised spots were analyzed by mass spectrometry. Three main proteins resulted in the identification have not been described in other bee venoms before. Dose-dependence against human carcinoma (Hep3B, BT-20, A549 and AGS) were observed from 1ng/ml to 100ng/ml. Expecially, the treatment of 100ng/ml B. ignitus venoms showed the highest cytotoxicity with 55% against hepatocellular carcinoma (Hep3B). The B. ignitus venoms showed strong antimicrobial activities against Enterococcus faecium and Shigella sonnei, and practically antimicrobial activity against the other microorganisms tested. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of E. faecium and S. sonnei, were 0.256ug/ml, respectively.

Purified bee venom was collected from colonies of honeybees (Apis mellifera L.) using a bee venom collector under sterile conditions and then purified under strict laboratory conditions. Purified bee venom contained 63.9±5.4% melittin, 10.9±1.6% phospholipase A2, and 2.3±0.3% apamin. Purified bee venom has various anti-bacterial, anti-inflammatory and immunostimulating effects. In this study, we evaluated purified bee venom which are mammary gland cells, MAC-T cells are used to increase the synthesis of milk protein. Purified bee venom promoted the proliferation of MAC-T cells at concentrations below 1 μg/mL, but cytotoxicity at 10 μg/mL and above. As a result of the increase in the synthesis of β-casein, a milk protein after treatment with MAC-T cells at a concentration of the bee venom without cytotoxicity, the β-casein content in the cell culture was increased when treated at a concentration of 1 ng/mL or more. In addition, it was confirmed that purified bee venom significantly increased the expression of bovine β-casein (bCSNB) mRNA, a β-casein synthesis gene, at a concentration of 1 ng/mL or more. These results suggest that purified bee venom can be used to increase the production of livestock by ultimately increasing the expression of milk protein

도토리화분의 총 폴리페놀함량은 화분배지에 뽕나무버섯(Armillaria mellea) 배양한 발아액에서 가장 높았으며, 표고(Lentinula edodes) 발아액에서 가장 낮았다. 뽕나무버섯을 배양한 발아액 중에서 동결건조 화분의 발아액이 정제화분과 저온초미분쇄화분의 발아액보다 총 폴리페놀함량이 많았다. 또한 동결건조 화분의 뽕나무버섯 발아액은 물추출액보다 총 폴리페놀함량이 1.4배 높았다. 도토리화분의 DPPH radical 소거능은 뽕나무버섯 발아액에서 가장 높았으며, 표고 발아액에서 가장 낮았다. 동결건조 화분의 뽕나무버섯 발아액은 DPPH radical 소거능이 물추출보다 2~4배 높았다. 수집된 꿀벌화분은 알갱이 형태이며, 꿀벌의 분비물을 제거한 순수 화분은 분말형태로 크기는 0.1~0.003 mm 정도이다. 화분의 전자현미경 구조는 도토리화분은 단립이며 모양은 장구형(prolate)이고 극면상은 난형이다. 발아구는 3구형이며 비교적 짧고 곧은 주름이 있다. 표면은 과립상(verrucate) 또는 미립상(scabrate)으로 불규칙한 돌기가 있다. 저온초미분쇄한 화분은 세포벽이 파쇄 또는 절단되었으며, 동결건조한 화분에서는 세포벽이 파열되어 세포질이 나출되는 양상을 보였다. 표고를 접종한 도토리 화분의 세포 발아 형태는 공구(pore) 주변에 외피가 없는 다량의 발아세포가 형성되었으며, 뽕나무버섯을 접종한 화분배지에서의 세포 발아 형태는 화분에서 균사속과 유사한 발아관이 형성되고 그 끝에 발아세포가 형성되었다. In this study, we measured antioxidant activity as DPPH radical scavenging and the total polyphenol content of pulverized and lyophilized oak pollens inoculated with fungi to confirm the husk removal effect. The total polyphenol content of oak pollen was highest in lyophilized pollen medium inoculated with Armillaria mellea, and was lowest in pollen inoculated with Lentinula edodes. Total polyphenol content of the lyophilized pollen was higher than that of the refined pollen and the pulverized pollen in oak pollen germinated with A. mellea. The total polyphenol content of the lyophilized oak pollen germinated with A. mellea was 1.4-fold higher than that extracted with water. Measurement of antioxidant activity using the DPPH (2, 2 diphenyl-1- picrylhydrazyl) free radical scavenging method showed that the lyophilized oak pollen germinated with A. mellea had the highest and that germinated with L. edodes was lowest in antioxidant activities. The lyophilized oak pollen germinated with A. mellea was 2 to 4 times higher than that extracted with water in the antioxidant activity of DPPH free radical scavenging. Many germinated cells were formed around pore of acorn pollen inoculated with L. edodes, while those were formed at the end of hyphae derived from oak pollen inoculated with A. mellea.
