LOWER POSTPRANDIAL PLASMA GLUCOSE AND INSULIN AFTER ADDITION OF ACACIA CORIACEA FLOUR TO WHEAT BREAD

Many Australian Aboriginal bushfoods contain slowly digested carbohydrate which elicit low postprandial blood glucose and insulin responses compared to Western foods, such as wheat bread. This study has shown that incorporation of flour made from a slowly digested seed, Acacia coriacea , into wheat bread (18 g/82 g wheat flour) significantly reduces the initial rise in plasma glucose levels ( p < 0.05) and the area under the plasma glucose curve ( p < 0.005) in six healthy subjects. Insulin values were also lowered at 60 minutes ( p < 0.025) and 90 minutes ( p < 0.05). Our findings suggest that Acacia flour, when used to dilute wheat flour in the manufacture of breads, produces a very palatable food which could be useful in the diets of diabetic individuals.

Essential oils of Salvia bracteata and Salvia rubifolia from Lebanon: Chemical composition,antimicrobial activity and inhibitory effect on human melanoma cells

Aim of the study

Salvia bracteata Banks et Sol. and Salvia rubifolia Boiss. are known in folk medicine of Lebanon for the treatment of microbial infections, cancer, urinary and pulmonary problems. In the present study the chemical composition and antimicrobial activity of essential oils from aerial parts of Salvia bracteata and Salvia rubifolia collected in Lebanon were evaluated. The oils were also tested for their potential antiproliferative effects against M14 human melanoma cells.

Material and methods

The oils were studied by GC and GC–MS and their antibacterial activity (MIC and MBC) was tested against ten bacteria species using the broth dilution method. The inhibitory effect on human melanoma cells (measurement of cell vitality, cell membrane integrity and genomic DNA fragmentation) was studied using MTT assay, calculation of LDH release and COMET assay.

Results

The oils showed a good antibacterial activity (MIC = 50 μg/ml) against Gram+ bacteria. They besides exhibited an inhibitory effect on the human cancer cells examined inducing also apoptotic cell death, but the oil of Salvia rubifolia was significantly (p < 0.001) more active as compared to the oil of Salvia bracteata.

Conclusion

The results on the pharmacological activities of these Salvia species provide an in vitro scientific support for the use of these plants in traditional herbal preparations.     

放射性125I粒子组织间植入或联合放化疗治疗复发直肠癌

目的探讨超声或CT引导下放射性125I粒子组织间植入治疗复发直肠癌的技术可行性、近期疗效和副反应.方法 15例直肠癌术后盆腔复发患者,女4例,男11例.硬膜外麻醉,2例经阴道超声引导,13例CT引导,行放射性125I粒子植入术.肿瘤匹配周边剂量为90～110 Gy,每颗粒子活度为0.50～0.70 mCi,植入33～70颗.术后24～48 h拍胸、盆腔X线片了解粒子是否发生移位.术后6例加三维适形放疗,4～6野/次,200～300 cGy/次,5次/周,总剂量为4 500～5 000 cGy,间隔4周.2例粒子治疗后加草酸铂、5-氟尿嘧啶和四氢叶酸化疗1个周期,随访3～15个月,根据CT扫描结果判断肿瘤大小. 结果术后平均7天疼痛缓解,其中12例完全缓解,2例部分缓解,1例无变化,有效率93%(14/15).9例肿瘤完全缓解,2例部分缓解,4例局部进展,局部控制率73%(11/15).2例术后6个月和12个月时死于肺转移.1例1颗粒子移位至盆壁,随访12个月无症状.无治疗相关并发症和副作用发生. 结论经超声或CT引导放射性125I粒子植入治疗复发直肠癌具有安全、微创、并发症发生率低和疗效肯定等优势,粒子治疗后应配合外放疗和全身化疗,有望进一步提高疗效.     

参附注射液对大鼠胰腺移植受体小肠肠粘膜屏障的保护作用

目的探讨参附注射液（SF）对大鼠胰腺移植受体肠粘膜屏障的保护作用及机制。方法24只糖尿病大鼠随机分为缺血再灌注组（IR组。n=12），参附注射液预处理组（SF组．n=12），12只正常大鼠为对照组，IR组和SF组大鼠均接受胰腺移植，再灌注后5d检测小肠通透性和吸收功能，检测血清TNF-α、NO、SOD和淀粉酶活性，取受体空肠粘膜组织检测小肠粘膜粘膜湿重、微绒毛高度及宽度、MDA含量及MPO活性，同时取肠系膜静脉血、肠系膜淋巴结、肝及脾组织进行细菌培养，观察细菌易位情况。结果再灌注后SF组血清TNF—α含量（P〈0．01）、淀粉酶活性（P〈0．01）、MDA含量（P〈0．01）、MPO活性（P〈0．01）、小肠通透性（P〈0．01）、细菌易位率（P〈0．01）和小肠粘膜损伤程度均低于IR组；血清NO和SOD含量、小肠吸收功能均高于IR组（P〈0．01）。结论SF预处理可保护大鼠胰腺移植受体小肠肠粘膜屏障，降低细菌易位率，机制可能与降低胰酶活性、减少TNF—α生成、减轻PMNs粘附与聚集、增加NO和SOD含量有关。     

参附注射液对实验性急性坏死性胰腺炎肠道细菌移位的影响

目的：研究参附注射液对实验性急性坏死性胰腺炎（ANP）时肠道细菌移位的影响。方法：ANP大鼠制模方法采用胰腺被膜下注射牛磺胆酸钠。假手术组、对照组经皮下注射生理盐水，实验组同法给予等量参附注射液。取标本（下腔静脉血、腹水、肠系膜淋巴结及大肠内容物）进行细菌培养，计数菌落数及鉴定细菌种类。结果：标本中生长的细菌与大肠内容物培养细菌种类相同，实验组标本的菌落数少于对照组（P〈0.01）。结论：实验性ANP大鼠合并感染的细菌来源于肠道，参附注射液可以减少肠道细菌移位。
