Breast cancer is the most common cancer in women in Middle East countries. Despite the continuous efforts to increase the public awareness of breast cancer via campaigns and public screening programs, breast cancer screening rate remains low. The participation of community pharmacists in the communication and dissemination of breast cancer screening information should have a significant positive impact. The objectives of this study were to assess the degree of community pharmacists’ participation in breast cancer health promotion activities in United Arab Emirates (UAE), to evaluate their attitudes towards the involvement in breast cancer health promotion and receiving breast cancer continuous education. The study objectives were addressed in a cross-sectional survey distributed to community pharmacists in Sharjah, Dubai and Ajman Emirates (UAE). The survey measured the extent of community pharmacists’ participation in breast cancer health promotion activities, their interest and comfort in providing breast cancer health promotion, and their perceived barriers for integrating breast cancer health promotion activities into their daily practice. Over a 24-week period, we collected 275 surveys out of 335 pharmacists approached (82% response rate). Ninety-six percent indicated that they never invited healthcare professionals to provide breast cancer education in the pharmacy, 67% said that they never distributed breast cancer educational materials and 47% reported that they never counseled patients about breast cancer. Nevertheless, more than 75% were highly interested in being engaged in breast cancer health promotion activities. In addition, 87% believed that discussing breast cancer awareness with female patients in the pharmacy was beneficial to patients. Yet pharmacists perceived many barriers for integrating breast cancer health promotion into their daily practice including lack of educational materials (87%) and lack of enough time (74%). Moreover, their breast cancer knowledge mean score was 51% with 87% expressing a high interest in receiving breast cancer continuous education. Despite their low participation in breast cancer health promotion, the mainstream of pharmacists was interested in educating patients about breast cancer. However, low breast cancer knowledge and other barriers can prevent actualizing this role.
乳腺癌是中东国家女性中最常见的癌症。尽管通过宣传活动和公众筛查项目不断努力提高公众对乳腺癌的认识,但乳腺癌筛查率仍然很低。社区药师参与乳腺癌筛查信息的沟通和传播应会产生显著的积极影响。本研究的目的是评估阿拉伯联合酋长国社区药师参与乳腺癌健康促进活动的程度,评估他们对参与乳腺癌健康促进和接受乳腺癌继续教育的态度。研究目标在沙迦、迪拜和阿治曼酋长国(阿联酋)的社区药剂师中进行了横断面调查。该调查测量了社区药剂师参与乳腺癌健康促进活动的程度,他们对提供乳腺癌健康促进的兴趣和舒适度,以及他们认为将乳腺癌健康促进活动纳入日常实践的障碍。在24周的时间里,我们收集了335名药剂师的275份调查(82%的回复率)。96%的受访者表示,他们从未邀请医疗保健专业人员在药房提供乳腺癌教育,67%的受访者表示,他们从未分发乳腺癌教材,47%的受访者表示,他们从未就乳腺癌问题向患者提供咨询。然而,超过75%的人对参与促进乳腺癌健康的活动非常感兴趣。87%的人认为在药房与女性患者讨论乳腺癌意识对患者有益。然而,药剂师认为将乳腺癌健康促进纳入其日常实践存在许多障碍,包括缺乏教育材料(87%)和缺乏足够的时间(74%)。此外,她们的乳腺癌知识平均得分为51%,其中87%表示对接受乳腺癌继续教育有很高的兴趣。尽管他们在促进乳腺癌健康方面的参与度很低,但主流药剂师对教育患者了解乳腺癌很感兴趣。然而,低乳腺癌知识和其他障碍可以阻止实现这一作用。

The present study was directed to evaluate the toxic effects of orally administered titanium dioxide naonparticles (TiO2) on liver of male albino rats and to evaluate the ameliorative effects of N-acetylcysteine (NAC). Forty adult male albino rats were divided into 4 groups; control group, NAC group, TiO2 group and TiO2/ NAC group. Rats were administered either TiO2 (1200 mg kg-1 BW) or NAC (100 mg kg-1 BW) alone or together for 9 months. Blood was taken to evaluate serum changes in GPT, GOT and MDA levels. Liver tissues were examined for changes in MDA, GSH and changes in liver histopathology. Administration of TiO2 increased serum GPT, GOT and decreased MDA levels. Co-treatment of rats with NAC and TiO2 improved such significant changes induced by TiO2 alone. Moreover, significant time dependent increase in MDA and decrease in GSH levels in liver tissues were recorded. Liver histopathology showed vacuolar, hydropic degeneration and cell death of some hepatic cells. In conclusion, results confirmed the protective effect of NAC in amelioration of the biohazard effects induced by TiO2 in rats.
本研究旨在评价口服二氧化钛纳米颗粒(TiO2)对雄性白化大鼠肝脏的毒性作用,并评价n -乙酰半胱氨酸(NAC)的改善作用。40只成年雄性白化大鼠分为4组;对照组、NAC组、TiO2组和TiO2/ NAC组。给大鼠单独或联合给予TiO2 (1200 mg kg-1 BW)或NAC (100 mg kg-1 BW) 9个月。取血评估血清GPT、GOT和MDA水平的变化。检测肝组织丙二醛、谷胱甘肽的变化及肝组织病理学变化。TiO2可提高血清GPT、GOT水平,降低MDA水平。NAC和TiO2共处理大鼠,改善了单独TiO2诱导的这种显著变化。此外,肝组织中MDA升高和GSH降低的时间依赖性显著。肝组织病理学表现为部分肝细胞空泡、水变性及细胞死亡。综上所述,NAC具有改善TiO2对大鼠生物危害的保护作用。

The present study aimed to evaluate the potential e fficiency of Deferasirox (DFX) and Desfferioxamine (DFO) as chelating agents in removing lead from rats as a biological model. Two different doses of lead (II) chloride (40 and 80 mg kg -1 body weight) were used for 45 days. After this per iod, all rats showed toxicity symptoms through loss of hair, greenish mottling on the live r, appearance of red dots around eyes and weakness. After lead administration, chelation therapy was done in removing the toxic metal from the biological system . The abilities of DFX and DFO chelators in removal of le ad from the body were studied for 10 days. Lead and iron concentrations in different tissues were measured b y Flame Atomic Absorption Spectroscopy (FAAS). Our results showed that two chelators can be more effec tive as combined therapy than as single therapy in removing lead from the body and also, toxicity symp toms are decreased. It could be concluded that DFX and DFO chelators could be used for the treatment of co mplication of lead intoxication symptoms.

Antimicrobial activity and chemical composition of the essential oil of Juniperus communis (L.), originated from east part of Kosova, was investigated. The ess ential oil from berries of J. communis (L.), obtained by hydro-distillation was analyzed by GC and GC-MS. Antimicrobial properties of the essential oil of J. communis (L.) are investigated and results are submitted fo r their activities against Staphylococcus aureus , Escherichia coli , Hafnia alvei and Pseudomonas aeruginosa . Applying the agar disc diffusion technique, we measured diameters of the inhibition zone around discs, which are previously wetted with DMF soluti on of the essential oil with three different concentra tions, 1, 3 and 5 mg mL -1 . Analysis of the oil resulted in the identification of 41 peaks, representing 96% of the oil. Berry essential oil composed mainly of monoterpenoids which amounted to 83%, of which 69.4% was monoterpene hydrocarbons. The main monoterpene hydrocarbons were α-pinene (36.2%) and β-myrcene (21.1%). The sesquiterpene accounted for about 13.4% of the total oil composition. Germa crene D (2.2%), α-cadinol (1.6%), α-humulene (1.5%), spathulenol (1.4%), epi-α-bisabolol (1.3%) and germacrene B (1.1%) were the main constituents of the sesquiterpenes. The inhibition zone depends from co ncentrations and also from sort of bacteria. The inhibition zones differ from 0-39 mm. The present work presents the chemical composition of the hydrodistilled oil of J. communis (L.) from East part of Kosova and the results are compared to those reported in the literature. This study demonstrates the occurrence of α-pinene chemotype of J. communis (L.) from east part of Kosova. The essential oil of J. communis (L.) growing wild in Kosova, showed moderate to high activities against Staphylococcus aureus , Escherichia coli , Hafnia alvei . Pseudomonas aeruginosa is resistant to the essential oil of J. communis (L.) growing wild in east part of Kosova.
对原产于科索沃东部的杜松(Juniperus communis, L.)精油的抑菌活性和化学成分进行了研究。采用气相色谱和气相色谱-质谱联用技术对水蒸馏法提取的小檗(J. communis (L.))果实中挥发油进行了分析。研究了金丝桃精油的抑菌活性,并报道了其对金黄色葡萄球菌、大肠杆菌、肺泡Hafnia和铜绿假单胞菌的抑菌活性。应用琼脂圆盘扩散技术,我们测量了圆盘周围抑制区的直径,圆盘之前用三种不同浓度的精油DMF溶液湿润,分别为1、3和5 mg mL -1。对油进行分析,鉴定出41个峰,占油的96%。浆果精油主要成分为单萜类化合物,占总成分的83%,其中单萜类化合物占69.4%。单萜烃主要为α-蒎烯(36.2%)和β-月桂烯(21.1%)。倍半萜约占总油成分的13.4%。倍半萜的主要成分为日耳曼烯D(2.2%)、α-二酚(1.6%)、α-葎草烯(1.5%)、spathulenol(1.4%)、epi-α-双abolol(1.3%)和日耳曼烯B(1.1%)。抑制区取决于浓度,也取决于细菌种类。抑制带在0 ~ 39 mm之间。本工作介绍了科索沃东部的J. communis (L.)的水蒸馏油的化学成分,并将结果与文献报道的结果进行了比较。本研究证实了科索沃东部地区的J. communis (L.)存在α-蒎烯化学型。在科索沃野生生长的金针叶挥发油对金黄色葡萄球菌、大肠杆菌、肺泡Hafnia有中高活性。铜绿假单胞菌对生长在科索沃东部的野生金丝桃精油具有抗性。

Mature cell release takes place through the hypothetical barrier- the bone marrow-blood barrier. It consists of blood vessels and cells that surround them. Such cells are, among others, megakaryocytes. They are involved in the release of platelets or other cellular components of blood. The amount and the development of megakaryocytes and thus the maturity of barrier depends on many factors. One of them is IL-6, which gene is located on the short arm of chromosome 7 (7p15-p21). The study was performed on wild-type mice (C57B4/6J) and on mice lacking the gene encoding IL-6 (IL-6 KO-C57B4/6J IL-6tm1 Kopf-/-). Bone marrow of all animals in both groups has been collected, fixed and stained. Megakaryocytes were identified in each microscopic specimen using immunohistochemical reaction with the CD61 antibody. Then all specimens were subjected to histomorphometric analysis. Statistically significant differences in the total number and size of magakariocytes was noted, which affects bone marrow-blood barrier functions. This could be used in the conventional treatment of cancer, respiratory diseases and coagulation disorders and in the treatment using nanoparticles.
成熟细胞通过假定的屏障——骨髓-血液屏障释放。它由血管和周围的细胞组成。这些细胞包括巨核细胞。它们参与血小板或其他血液细胞成分的释放。巨核细胞的数量和发育以及屏障的成熟取决于许多因素。其中之一是IL-6,该基因位于7号染色体短臂上(7p15-p21)。研究对象为野生型小鼠(C57B4/6J)和缺乏IL-6编码基因(IL-6 KO-C57B4/6J IL-6tm1 Kopf-/-)的小鼠。两组动物均采集骨髓,固定并染色。利用CD61抗体免疫组化反应在每个显微镜标本中鉴定巨核细胞。然后对所有标本进行组织形态学分析。在影响骨髓-血液屏障功能的magakariocytes的总数和大小上有统计学上的显著差异。这可以用于癌症、呼吸系统疾病和凝血功能障碍的常规治疗,也可以用于纳米颗粒的治疗。

To establish the wound healing activity of aqueous and ethanolic extract of roots of Morus alba. Two models were performed to evaluate the wound healing activity i.e., Incision and Excision model. In incision model the parameter which was carried out was breaking strength of wounded skin. In excision model percentage wound contraction and period of epithelialization was established for both the extracts. Reference standard drug was Aloe vera ointment for comparison with other groups. From the observation in both the models, Aq. extract of Morus alba was found to have greater wound healing activity in terms of breaking strength in incision model and percentage wound contraction, period of epithelialization was highest in excision model compared with other groups. In conclusion, our findings suggest that aq. extract of Morus alba possess better healing ability than the ethanolic extract.
目的:建立桑根水提液和乙醇提液的创面愈合活性。采用切口和切除两种模型评价创面愈合活性。在切口模型中,计算的参数为损伤皮肤的断裂强度。在切除模型中,测定两种提取物的创面收缩率和上皮化时间。对照标准药物为芦荟软膏,与其他组进行比较。从两组模型的观察来看,桑叶提取物在切口模型的破断强度和切除模型的创面收缩率、上皮化时间等方面均较其他组具有更大的创面愈合活性。综上所述,我们的研究结果表明,桑叶提取物比乙醇提取物具有更好的愈合能力。

Gastric ulcer healing is a complex process that is regulated by several promoting factors including COX-2 and iNOS. Diabetes mellitus is usually associated with delayed gastric ulcer healing. Hence, the current study was designed to investigate the effect of sitagliptin (dipeptidyl peptidase-4 inhibitor) on gastric ulcer healing and expression of iNOS and COX-2 in rat stomach.The study was conducted on 30 rats divided into three equal groups. Group 1 served as normal control group. Gastric ulcer was induced, by serosal application of acetic acid, in group 2 (ulcer model group) and group 3 (sitagliptin-treated group). Sitagliptin was administrated from day 3 to day 10 in group 3. All rats were sacrificed on day 10 and stomachs were removed for pathological examination and immunohistochemical assessment of COX-2 and iNOS expression. Pathological examination revealed that gastric ulcer healing was significantly impaired in the sitagliptin-treated group as evidenced by the significantly larger ulcerated area and ulcer base maturation impairment.COX-2 and iNOS expression as well as mean MVD were significantly diminished in the sitagliptin-treated group as compared to the ulcer model group. A significant positive correlation was found between COX-2 and iNOS implying their synergistic action. We conclude that sitagliptin significantly impairs gastric ulcer healing in rats possibly through inhibition of iNOS and COX-2 expression. Our results raise the question of whether sitagliptin is advisable in diabetic patients with pre-existing gastric ulcer. Our preliminary experimental findings need to be substantiated by future human studies.
胃溃疡愈合是一个复杂的过程,受COX-2和iNOS等多种促进因子的调控。糖尿病通常与胃溃疡延迟愈合有关。因此,本研究旨在探讨西格列汀(二肽基肽酶-4抑制剂)对大鼠胃溃疡愈合及胃内iNOS和COX-2表达的影响。研究人员将30只大鼠分成三组。第1组为正常对照组。2组(溃疡模型组)和3组(西格列汀治疗组)采用乙酸浆液涂敷法诱导胃溃疡。第三组从第3天至第10天给予西格列汀。第10天处死大鼠,取胃进行病理检查,免疫组化检测COX-2和iNOS的表达。病理检查显示西格列汀治疗组胃溃疡愈合明显受损,溃疡面积明显增大,溃疡基底成熟损伤。与溃疡模型组相比,西格列汀治疗组COX-2和iNOS的表达以及平均MVD均显著降低。COX-2与iNOS呈显著正相关,表明二者具有协同作用。我们得出结论,西格列汀可能通过抑制iNOS和COX-2的表达而显著损害大鼠胃溃疡愈合。我们的结果提出了西格列汀是否适合糖尿病患者既往胃溃疡的问题。我们的初步实验结果需要通过未来的人体研究来证实。
