Total anthocyanins of spices (Syzygium aromaticum L., Coriadrum sativum L., Cuminum cyminum L., Zingiber officinale rosc., Elettaria cardamomum, Curcuma longa, rhus coriaria L., Cinnamomum zeylanicum Blume, Foeniculum vulgare Mill and Laurus nobilis L.) were determined using acidified (1% HCl) solvents (methanol, ethanol and acetone) at three temperatures (20℃, 40℃ and 60℃). Also phenolic acids were separated and identified by rP-HPLC. results showed that sumac and cinnamon had the highest levels of anthocyanins, while for the acetone the cinnamon indicated the highest amount of anthocyanins when methanol and ethanol were used as extracting solvents at 20℃. At 40℃ using ethanol, sumac showed the highest level of anthocyanins whereas acetone solvent yielded the highest anthocyanin contents for cinnamon. At 60℃, cinnamon showed the highest level of anthocyanins when methanol and acetone were the solvents, while sumac had the highest anthocyanins level using ethanol as solvent. HPLC results showed ten phenolic acids found in those spices and varied in their concentrations. Gallic acid had the highest level (1642.3 mg/100g) (cloves). Gentisic acid had the lowest level (1.2 mg/100g) in ginger. Also sumac showed the highest level of chlorogenic acid (1528.7 mg/100g). Some acids were not found in some spices, for instance, benzoic acid was not found in coriander, cumin, ginger, green cardamom, cinnamon and sweet laurel.

Ten spices marketed in jordan, (Syzygium aromaticum L., Coriadrum sativum L., Cuminum cyminum L.,Zingiber officinale rosc., Elettaria cardamomum, Curcuma longa, rhus coriaria L., Cinnamomum zeylanicum Blume, Foeniculum vulgare Mill and Laurus nobilis L.) were investigated for their phenolic compounds and antioxidant activity. The influence of different extractants (methanol, ethanol and acetone) at different temperatures (20, 40 and 60°C) was examined. results showed at 60°C using methanol, cloves had the highest level of total phenolics (781.0 mg GAE/100g using acetone). At 40°C, sumac and cloves had the highest amounts of total phenolics (343.9 mg/100g and 342 mg GAE/100g respectively). At 20°C, cloves continued to have the highest amount of total phenolics (394.7 mg/100g) using methanol as extactant. Ethanol as extractant, cloves gave the highest level of phenolics (548 mg GAE/100g, 493.4 mg GAE/100g) at 60°C, while at 20°C cloves and sumac showed the highest concentrations of phenolics (350.8 mg GAE/100g and 342.8 mg GAE/100g respectively). Acetone as extractant at 60°C, cloves had the highest levels of phenolics (781 mg GAE/100g) while at 40°C and at 20°C, sumac contributed the highest levels of total phenolics (583.2 mg GAE/100g and 754.5 mg GAE/100g). The total phenolics concentration varied significantly among the spices. Their values varied according to the extractant and extracting temperature. IC50 (radical scavenging activity) reflecting the antioxidant activity was presented. results showed that cloves had the highest antioxidant activity while the cinnamon, turmeric and sumac had a appreciable level of antioxidant activity. Green cardamom and coriander had the lowest antioxidant activity. Antioxidant activity was positively correlated with total phenolic compounds content of the investigated spices.

The present study showed significant initial microbial load, as well nutritional value of ten spices used widely across the world in food preparation. The microbiological tests demonstrated that sumac and cloves had the highest antimicrobial activity with respect to total plate counting and spore forming count. results showed that chemical composition of the spices and herbs varied significantly. Dry matter content ranged between 83.6% and 92.4%. The highest ash content 10.4% was found in sweet cumin, protein 21.2% in cumin, fat 19.7% in sumac, fiber 59.2% in turmeric and carbohydrates 27.3% in sumac. These spices were also differing in their minerals content. Substantial amounts of Ca, Na, K and Mg were found, while Cu, Fe, P, Mn and Zn were present in trace amounts in all investigated spices.

世界核心医学期刊文摘（儿科学分册） 2005年第5期1卷 58-58页

作者： Merei j. M. 肖莉 Department of Pediatric Surgery Faculty of Medicine Jordan Univ. of Sci. and Technology Irbid Jordan

Background/Purpose The covering of the sutured surgical wound with a sterile d ressing is usually considered a routine conclusion to an aseptic operation. The wound is usually left dressed for a minimum of 3 to 5 days. The main purpose of dressing is protection of the wound against bacterial contamination that remains a significant source of postoperative morbidity. The aim of this study was to c ompare the infectious local risk when the clean pediatric surgical wounds were d ressed or left exposed without dressing after the completion of wound closure. M ethods Four hundred fifty-one patients with clean surgical wounds were randomiz ed prospectively to receive dressing (n = 216) or have their wounds left exposed without any dressing (n = 235) after the completion of wound closure. results I n the group that received wound dressing, wound infection developed in 3 patient s (1.4%), whereas in the group that had wounds exposed without any dressing, 4 patients (1.7%) developed wound infection. Conclusions In children, there was no significant difference in terms of wound infection after applying dressing o r leaving the clean surgical wounds exposed without any dressing after completio n of wound closure. Dressing clean surgical wounds may be unnecessary.

高龄、糖尿病(DM)和慢性肾脏疾病(CKD)不仅会增加慢性冠状动脉综合征(CCS)患者缺血事件的风险,还会增加其接受抗血小板治疗期间的出血风险。此类特殊人群可能需要调整治疗方案,尤其是亚洲的特殊人群,往往表现出与西方人群不同的临床特征。关于亚洲人群CCS高风险的分类和急性冠状动脉综合征(ACS)后使用新一代强效P2Y12受体抑制剂(如替格瑞洛和普拉格雷)的国际指南已相继发表。本共识总结了在特殊人群中使用强效P2Y12受体抑制剂的相关证据,提出了在冠状动脉疾病(CAD)特殊人群中应用标准疗程双联抗血小板治疗(DAPT)、短期DAPT和单一抗血小板治疗的推荐意见。本共识的特殊人群包括从ACS过渡至CCS,老年,或患有CKD、DM、多血管CAD和治疗期间发生出血并发症等特征的患者。
