This study aimed to determine the effects of vitamin C and propolis-supplemented feeds on some blood parameters, lipid peroxidation, and activities of some antioxidant enzymes in broilers exposed to oxidative stress. 360 three-day-old broiler chicks (Ross 308) were randomly divided into four treatment groups each containing 90 animals, including six replicate groups for each treatment. The experimental groups were designated for a 3-42 days period as follows: no supplement to basal ration (Control-Group I); supplement of 500 ppm vitamin C and 200 ppm lead (as lead acetate) to basal ration (Group II); supplement of 1 g/kg propolis and 200 ppm lead (as lead acetate) to basal ration (Group III); and supplement of 200 ppm lead (as lead acetate) to basal ration (Group IV). The highest TG level (86.83 mg/dl) was observed in the lead supplemented group; however, the lowest aspartate aminotransferase (SGOT) level (90.71 IU/L) was observed in the control group (p<0.05). The addition of lead increased the plasma malondialdehyde (MDA) level (p<0.01) compared to other treatments. However, the addition of vitamin C and propolis decreased the plasma MDA level close to control levels. The highest erythrocyte superoxide dismutase (SOD) activity was observed in the lead addition group (p<0.01) while no significant differences were observed for SOD activities of the control, vitamin C +lead, and propolis+lead groups. The plasma reduced glutathione (GSH) activity of the control ($2.30{\mu}mol$/ml) was significantly lower than the lead administered group ($6.20{\mu}mol$/ml) (p<0.01); while this parameter was determined to be similar to other groups. No significant differences were observed between groups for liver GSH activity, but heart GSH activity of the control was significantly higher in comparison to other treatments (p<0.05). To obtain similar antioxidant effects, it is recommend that using propolis (1 g/kg) and vitamin C (500 mg/kg) supplementation in broiler diets may overcome the adverse effects of oxidative stress originating from dietary lead.

Propolis is a resinous substance that is collected by Apis mellifera from plant sources and is used in traditional medicine. To study the phytochemical constituents and apoptotic potential of Jordanian propolis extract against different cancer cell lines, propolis was extracted using methanol, hexane, and ethyl acetate and was fractionated using chromatographic methods. Cytotoxicity was assessed using MTT and LDH assays. The apoptotic potential was investigated using florescence microscopy, multicaspase assay, Annexin-V and dead cell assay, and cell cycle assay. The phytochemical constituents were analyzed using GC-MS. The methanol extract of propolis exhibited cytotoxic potential against all cell lines tested. The IC₅₀ values of the methanol extract were 47.4, 77.8, 91.2, and 145.0 ㎍/ml for HepG2, LoVo, MDAMB231, and MCF7 cell lines, respectively. The IC₅₀ values of the F1 fraction were 31.6 (MDAMB231), 38.9 (HepG2), 36.7 (LoVo) and 75.5 (MCF7) ㎍/ml. On further purification using thin-layer chromatography, the IC₅₀ values of the F1-3 fraction were found to be 84.31(HepG2), 79.2 (MCF7), 70.4 (LoVo), and 68.9 (MDAMB231) ㎍/ml, respectively. The anticancer potential of the F1 fraction was confirmed through the induction of apoptosis and cell cycle arrest at the G0/G1 phase. The GC-MS analysis of the F1 fraction revealed the presence of 3-methyl-4-isopropylphenol (29.44%) as a major constituent. These findings indicate the potential of propolis extract as a cancer therapy. However, further investigation is required to assess the acute and subacute toxicity of the most active fraction.

We investigated the effects of dietary supplementation of two types (powder or liquid) of propolis on innate immunity and disease resistance of olive flounder Paralichthys olivaceus against Edwerdsiella tarda. A total of 600 fish averaging 30 g were randomly distributed into 24 tanks in groups of 25. Three tanks were assigned to each of eight experimental diets: 0 (Control), 0.25, 0.5, 0.75 and 1 % propolis in powder form and 0.25, 0.5 and 1 % propolis in liquid form (PP0.25, PP0.5, PP0.75, PP1, LP0.25, LP0.5 and LP1, respectively). Fish were fed each experimental diet twice daily for four weeks to apparent satiation. At the end of the feeding trial, lysozyme and myeloperoxidase activities and total immunoglobulin level were significantly higher in fish fed the PP1 and LP0.5 diets compared to those fed the control diet. The PP1 diet was also associated with a significant increase in anti-protease activity compared to the control diet. After challenge with E. tarda, fish fed the LP0.5 diet showed numerically higher survival compared to the other groups. This study indicates that non-specific immune responses of olive flounder can be enhanced by dietary supplementation with powder and liquid forms of propolis, and that the optimal level would be 1% in powder form or 0.5% in liquid form. It seemed that growth performance and feed utilization are not affected by the propolis supplementation in diets for olive flounder.

Propolis는 꿀벌들이 나무로부터 수집한 천연물로서 항산화, 항염증, 항암 효과를 가지고 있어 전통의학에서 사용되고 있으며, 이러한 생리활성은 여러 가지 유용성분들이 혼합된 것과 관련이 있다. 난소암은 우리나라 여성에서 두 번째로 발병률이 높은 암이다. 대부분의 난소암 환자들은 초기에 수술적 기법과 항암요법에 우수하게 반응하지만, 항암제 내성에 의한 재발이 발생하게 되면 항암요법제에 의한 반응률이 매우 저조하여 높은 사망률을 보인다. 따라서, 난소암의 높은 치사율을 극복하기 위한 새로운 치료제 및 항암보조제의 개발이 필요하다. 본 연구에서는 인체 상피성 난소암 세포주인 A2780를 이용하여 Austalian propolis의 항암 효과와 활성기전을 조사하였다. Propolis 추출물은 농도 의존적으로 난소암 세포의 증식을 억제했으며. Flow cytometric 분석을 통해 G0/G1기에서 세포 주기 억제와 apoptosis 유도 효과를 확인하였다. 이러한 결과는 Austalian propolis의 인간 난소암에 대한 예방과 치료를 위한 보조제로서의 가능성을 제시한다.

본 연구는 프로폴리스가 방사선에 조사된 랫드의 여러 조직에 미치는 방사선 방어 효과를 조사하였다. 혈장성분 중 백혈구의 수는 방사선 조사 20일 경과 후에 방사선만 조사한 실험군보다 프로폴리스 섭식 실험군에서 높은 증가를 나타냈으며, 혈장 성분 중 GOT의 활성도는 GPT에 비해 낮아지고 있다. 간 조직 내 미량원소 중 Mg, Fe, Ca, Mn, Cu, Mo, Ni, As의 함량은 대조 군에 비해서는 증가하였으나 방사선만 조사한 실험군에 비해서는 낮은 수준을 유지하고 있다. 즉 프로폴리스는 백혈구 수의 회복에 효과적이며 방사선으로 인한 간세포의 손상을 보호해 줌으로서 미량원소의 방출을 억제하고 GOT의 활성을 낮춰주는 것으로 생각된다. 조직학적으로 방사선조사 전에 프로폴리스를 섭식하면 정소에서는 훼손된 미분화 세포의 수가 감소하였고, 소장에서도 손상된 배상세포와 점막근판 조직의 형태가 부분적으로 정상적인 형태를 갖추는 것으로 관찰되었다. 따라서 프로폴리스의 섭식은 방사선으로부터 직접적으로 조직을 보호하거나 훼손된 세포의 회복에 영향을 미치는 것으로 조사되었다.

In the present study, we carried out quantitative analysis of chrysin and pinocembrin in Korean propolis by ultra performance liquid chromatography (UPLC) equipped with diode array detector. The separation was done using BEH C18 ($2.1{\times}50mm$, $1.7{\mu}m$) column with a mobile phase consisting of MeCN and 0.1% $H_3PO_4$ at 280 nm. The chromatographic method was validated for specificity, limit of detection, limit of quantification, linearity, precision, and accuracy. A quantitative analysis exhibited that the contents of the two compounds in Korean propolis collected from 8 inland areas except Jeju-do ranged from 3.1-46.0 mg/g. These results will be valuable as basic data for standardization of Korean propolis.

We have found out the relationship of nanoemulsion containing nano vitamin C, E and propolis and gingival disease. We've confirmed effect of nanoemulsion through the experiment of in vivo and in vitro. We tested cell viability of gingival fibroblast cells by MTT assay and mRNA appearance of interleukin-$1{\beta}$, using mouse that was guided inflammation. Anti-microbacterial activity for Antibacterial effect's experiment was carried out by using S.aureus and E.coli. In addition, inflammation tissue has been observed with scanning electrical microscopy. In this study, expression of interleukin-$1{\beta}$ was decreased after adding nanoemulsion containing nanovitamin C, E and propolis. We've also obtained good results from the test of Antibacterial effect against S.aureus and E.coli. Also, swelling of inflammation tissues observed by scanning electrical microscopy has gone down. In conclusion, we have gained confidence that nanoemulsion containing nano vitamin C, E and propolis has very high Antibacterial effect against bacteria in oral. And it made us guess that inflammation of gingival reduces after decreasing interleukin-$1{\beta}$. Thus, we expect that nanoemulsion containing nano vitamin C, E and propolis gives good effects to patient having gingival disease.
