Acacia nilotica, Ocimum sanctum, and Alpinia nigra are used traditionally in different ailments in rural settings of Bangladesh. These medicinal plants were studied for their total phenolic and total flavonoid contents as a partial approach to rationalizing the use of them. Antioxidant activity was also determined to measure ferric reducing power assay and 1,1 ’ -diphenyl-1-picrylhydrazyl radical (DPPH) scavenging activity. A. nilotica showed the highest total phenolic content while O. sanctum showed highest flavonoid contents among the studied three plants. Similarly, IC50 values of the extracts of A. nilotica, O. sanctum and A. nigra against DPPH were 39.62, 48.81, 70.85 μg/ml, respectively. The reducing power of the extract was found to beconcentration dependent and O. sanctum showed the highest reducing power followed by A. nilotica. The reducing power of these two plants was fairly close to the positive control of ascorbic acid. Further studies are suggested such as in-vivo testing and elucidation of the mechanism of action of inherited bioactive compounds to support its folkloric use in the treatment of diseases.
在孟加拉国的农村环境中,Acacia nilotica、Ocimum sanctum和Alpinia nigra传统上用于治疗不同的疾病。对这些药用植物的总酚和总黄酮含量进行了研究,作为合理使用它们的部分方法。还测定了抗氧化活性,以测定铁还原力测定法和1,1'-二苯基-1-双芳基肼基(DPPH)清除活性。在所研究的三种植物中,尼罗霉的总酚含量最高,而桑椹的黄酮含量最高。同样,尼罗霉、桑椹和黑曲霉提取物对DPPH的IC50值分别为39.62、48.81和70.85μg/ml。提取物的还原力呈浓度依赖性,桑椹的还原力最高,其次是尼罗霉。这两种植物的还原力与抗坏血酸的阳性对照相当接近。建议进行进一步的研究,如体内测试和阐明遗传生物活性化合物的作用机制,以支持其在治疗疾病中的民俗用途。

Excessive salt consumption is one of the hypertension factor leads to kidney disease, while telmisartan is one of antihypertensive drugs used in the therapy. Telmisartan not only blocks angiotensin receptor leads to the decrease of blood pressure, but it also activates peroxisome proliferator activated receptor gamma (PPAR-γ), inhibits transforming growth expression factor of beta-1 (TGFβ-1) and increases bone morphogenetic protein-7 (BMP-7). Whether telmisartan increases BMP-7 expression of excessive NaCl–induced Wistar rats are studied in this experiment. Twenty five male Wistars 2.5-3 months of age and 100-150 g BW rats were used in this research. They were grouped into 5, each consists of 5 rats. Group I (G I) as first negative control did not receive NaCl and telmisartan. G II as second negative control received NaCl but not telmisartan. G III, IV and V received NaCl and telmisartan 3, 6 and 12 mg/kg BW. The treatments were given every day within 8 weeks. At the day of 56 all rats were sacrificed by mean of neck dislocation and operated to take the kidney. The expression of BMP-7 was measured by immunohistochemistry technic. Data were expressed as mean ± standard deviation. They were analyzed by parametric (ANOVA) or nonparametric (Kruskal-Wallis) test. A value of p<0.05 was considered statistically significant. The results showed that intraglomerular and extraglomerular BMP-7 protein expression were higher in telmisartan-treated Wistar rats group than negative control group (p<0.05). In conclusion, intraglomerular and extraglomerular BMP-7 protein expression were higher in 8% sodium chloride-induced and telmisartan-treated male Wistar rats than the items of negative control group.
过量食盐摄入是导致肾脏疾病的高血压因素之一,替米沙坦是治疗中使用的降压药物之一。替米沙坦不仅阻断血管紧张素受体导致血压下降,还激活过氧化物酶体增殖物激活受体γ(PPAR-γ),抑制β-1转化生长表达因子(TGFβ-1),增加骨形态发生蛋白-7(BMP-7)。本实验研究了替米沙坦是否增加过量NaCl诱导的Wistar大鼠BMP-7的表达。本研究使用25只2.5-3个月大的雄性Wistar和100-150g BW大鼠。它们被分成5组,每组由5只大鼠组成。作为第一阴性对照的I组(G I)不接受NaCl和替米沙坦。作为第二阴性对照的G II接受NaCl,但不接受替米沙坦。G III、IV和V分别接受NaCl和替米沙坦3、6和12 mg/kg BW,8周内每天给药。在第56天,通过颈部脱位处死所有大鼠,并手术取肾。用免疫组织化学方法检测BMP-7的表达。数据表示为平均值±标准差。通过参数(ANOVA)或非参数(Kruskal-Wallis)检验对其进行分析。p<0.05的值被认为具有统计学意义。结果表明,替米沙坦组大鼠肾小球内和肾小球外BMP-7蛋白表达均高于阴性对照组(p<0.05)。

Asthma is a chronic inflammatory disease with multifactorial disorder of the airways, and was associated with T helper type 2 (TH2) cells. It is considered the results of complicated interactions between innate cells and structural cells, including dendritic cells (DCs), epithelial cells, mast cells (MCs), basophils, eosinophils and group 2 innate lymphoid cells (ILC2s), which finally sustains Th2 immunity in the pathogenesis of asthma. In this narrative review the details of roles of important innate cells against asthma are discussed to facilitate the future study of asthma.
哮喘是一种气道多因素紊乱的慢性炎症性疾病,与T辅助型2(TH2)细胞有关。它被认为是先天细胞和结构细胞之间复杂相互作用的结果,包括树突状细胞(DC)、上皮细胞、肥大细胞(MC)、嗜碱性粒细胞、嗜酸性粒细胞和第2组先天淋巴细胞(ILC2),后者最终在哮喘的发病机制中维持Th2免疫。在这篇叙述性综述中,讨论了重要的先天细胞对哮喘的作用细节,以促进未来对哮喘的研究。

The aim of the study is to analyze the reasons for the significant increase in terms of fixation of bone fragments when transferring patients to outpatient treatment. In 512 patients with closed fractures of the bones of the lower leg during Ilizarov's treatment under stationary conditions, the period of fixation of fragments was 59 ± 0.4 days, which is 42% less than in outpatient treatment (64 people). In both groups, the microscopic mobility of bone fragments was determined tensometrically in patients with limb functional loading. With the help of the SF-36 test, the quality of life was examined, and the state of autoregulation of the centers of the brain was assessed in terms of the range of changes in the rate of blood flow along the middle cerebral arteries in cases of muscle grasping. Discovered that the combination of medical and functional rehabilitation during the transition to outpatient mode with 3-weeks of treatment in patients of mature age reduced quality of life and increases the duration of the period of fixation of the bone, impairs auto-regulation of cerebral blood flow in functional muscle test.
本研究的目的是分析在将患者转到门诊治疗时,骨碎片固定方面显著增加的原因。在Ilizarov固定条件下治疗的512例小腿闭合性骨折患者中,碎片固定时间为59±0.4天,比门诊治疗(64例)缩短42%。在两组中,在肢体功能负荷患者中,骨碎片的显微活动性都是用张力法测定的。在SF-36测试的帮助下,研究人员检查了生活质量,并根据肌肉抓取时大脑中动脉血流速率的变化范围来评估大脑中心的自动调节状态。发现老年患者在向门诊模式过渡的3周治疗过程中,医学与功能康复相结合降低了患者的生活质量,增加了骨固定时间,损害了功能性肌肉试验中脑血流量的自动调节。

Background: Male infertility appears to be a major clinical problem among men of reproductive age in all societies. Idiopathic male infertility is considered to be a multifactorial disorder affected by genetic, environmental, and hormonal factors. Oxidative stress seems to stand out as one of the underlying mechanisms. In this context, we aimed to evaluate seminal plasma antioxidants SOD (superoxide dismutase), GPx (glutathione peroxidase), CAT (catalase) and zinc levels, hormone levels, and semen parameters in fertile donors and patients with unbalanced chromosomal abnormalities.Methods: Semen samples from 119 patients with unbalanced chromosomal abnormalities and 30 fertile men were analyzed according to World Health Organization guidelines (2010). All patients underwent a measurement of testosterone (T), follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Seminal plasma antioxidants activities of SOD, GPx, CAT and zinc concentration were measured using colorimetric methods.Results and conclusion: Hormonal analysis showed statistically significant increase of FSH and LH levels in all patients (p<0.001). However, a significant decrease of serum testosterone level was observed in patients compared to fertile group (p<0.05). Seminal antioxidant system evaluation revealed a significant decrease of CAT, GPx, SOD and zinc activities in infertile group compared to fertile group (p<0.05). Our study showed that patients with unbalanced chromosomal abnormalities had significant alterations of antioxidant system and a significant perturbation of hormonal levels which interfere with fertility. These alterations may be due to a loss or derangement of chromosomal segments containing genes involved in the regulation of these systems.
背景:男性不育似乎是所有社会育龄男性的主要临床问题。特发性男性不育症被认为是一种受遗传、环境和激素因素影响的多因素疾病。氧化应激似乎是其中一个潜在的机制。在此背景下,我们旨在评估精液中抗氧化剂SOD(超氧化物歧化酶)、GPx(谷胱甘肽过氧化物酶)、CAT(过氧化氢酶)和锌水平、激素水平和精液参数在可育供者和不平衡染色体异常患者中的含量。方法:根据世界卫生组织2010年指南,对119例不平衡染色体异常患者和30例可生育男性的精液样本进行分析。所有患者均接受睾酮(T)、促卵泡激素(FSH)和黄体生成素(LH)的测量。用比色法测定精浆中SOD、GPx、CAT的抗氧化活性和锌浓度。结果与结论:激素分析显示,所有患者FSH和LH水平均有统计学意义升高(p<0.001)。但与生育组相比,患者血清睾酮水平明显降低(p<0.05)。精液抗氧化系统评价显示,不育组CAT、GPx、SOD和锌活性显著低于可育组(p<0.05)。我们的研究表明,患有不平衡染色体异常的患者具有显著的抗氧化系统改变和显著的激素水平扰动,从而干扰生育。这些改变可能是由于包含参与这些系统调节的基因的染色体片段的丢失或紊乱。

Siddha Makardhwaja (SMD) is a classical Ayurvedic formulation markedly used as a traditional medicine in the rural population for various purposes, such as a stimulant, tonic, and rejuvenator. The present study was conducted to evaluate the effect of conventionally prepared SMD on different lipid-profi le parameters in experimental animals, for providing scientifi c database for its logical use in clinical practice. Acute toxicity tests were conducted to determine the LD50 of the drug. To fi nd out the effect of chronic administration of SMD on serum lipid profi le, it was administered chronically to the male Sprague-Dawley rats at a dose of 40 mg/kg for 28 days. During the lipid profi le study, we found out the following: There is a statistically signifi cant (p = 5 0.042) decrease in the triglyceride content of the serum of the male rat [21.71% decrease]. There is a [21.65%] increase in the LDL level of the serum of the male rat; the increase, though not signifi - cant, was prominent (p = 5 0.122). There is a statistically signifi cant (p = 5 0.042) decrease in the VLDL level of the serum of the male rat [21.71% decrease]. There is a statistically signifi cant (p 5 0.016) decrease in the HDL level of the serum of the male rat [20.36% decrease]. There is a statistically signifi cant (p = 5 0.041) increase in the Cardiac Risk Ratio [(CRR) 5 Total cholesterol/HDL ratio] of the male rat [23.45% increase]. There is a statistically signifi cant (p 5 0.026) increase in the Castelli’s Risk Index II [(CRI II 5 LDL/HDL ratio] of the male rat [51.50% increase]. There is a statistically signifi cant (p = 5 0.041) increase in the Atherogenic Coeffi cient (AC) of the male rat [40.39% increase].
Siddha Makardhwaja (SMD)是一种经典的阿育吠陀配方,在农村人口中作为一种传统药物,用于各种目的,如兴奋剂,滋补品和恢复活力。本研究旨在评价常规制备的SMD对实验动物不同血脂参数的影响,为其在临床的合理应用提供科学依据。进行了急性毒性试验,以确定药物的LD50。为了研究慢性给药SMD对雄性Sprague-Dawley大鼠血脂的影响,我们以40 mg/kg的剂量长期给药28天。在脂质谱研究中,我们发现:雄性大鼠血清甘油三酯含量下降有统计学意义(p = 5 0.042)[下降21.71%]。雄性大鼠血清LDL水平升高[21.65%];虽然增加不显著,但明显(p = 5 0.122)。雄性大鼠血清VLDL水平降低,差异有统计学意义(p = 5 0.042)[降低21.71%]。雄性大鼠血清HDL水平降低,差异有统计学意义(p 5 0.016)[降低20.36%]。雄性大鼠心脏危险比(CRR) 5总胆固醇/高密度脂蛋白比值[增高23.45%],差异有统计学意义(p = 5 0.041)。男性大鼠Castelli’s Risk Index II [(CRIⅱ5 LDL/HDL比值]升高51.50%,差异有统计学意义(p 5 0.026)。雄性大鼠的动脉粥样硬化系数(Atherogenic coefficient, AC)升高有统计学意义(p = 5 0.041)[升高40.39%]。

Background: Uterine rupture is an obstetrics complication which is still both clinical dilemma and broader public health problem in developing countries.Objectives: This study is aimed to establish the magnitude of uterine rupture, predisposing factors, maternal and fetal outcomes, and surgical options of management of uterine rupture at Nekemte referral hospital which is located in western Ethiopia.Methods: Case control study was conducted on 54 mothers with uterine rupture and 108 mothers for whom cesarean section was done for mechanical reasons or previous scar who were managed in the Obstetrics and Gynecologic ward of the hospital from July 2015 to July 2016. Data were collected from two groups by accessing medical records. Statistical Package for Social Sciences windows version 20 was used for data analysis. The association between uterine rupture and different variables were assessed by using odds ratio (OR) along with 95%CI.Results: A total of 3,808 deliveries were conducted during the study period. There were 3206 vaginal deliveries, 548 cesarean deliveries and 54 uterine rupture cases. This makes 1 uterine rupture to happen in 70.5 deliveries. Majority, 87%, of uterine rupture occurred in unscarred uterus. The predisposing factors for uterine rupture were parity ≥ 5 (OR=4.37, 95% CI: 1.05, 18.23), lack of antenatal care (OR=7, 95% CI: 1.81, 27.02), lack of formal education (OR=2.38, 95% CI: 1.08, 5.26), household income less than 100 United States’ Dollar OR=14.08, 95% CI: 3.25, 62.5), previous home delivery (OR=9.10, 95% CI: 3.92, 21.11), and intrapartal follow up at health center or private clinics (OR=24.14, 95% CI: 5.60, 104.15). Uterine rupture caries more maternal (1.85% vs. 0%) and neonatal mortalities (96.3% vs. 3.7%) when compared to mothers delivered by cesarean section.Conclusion: Magnitude of uterine rupture was high in the study area. It carries more maternal and perinatal complications. There were numerous modifiable predisposing factors.
背景:子宫破裂是一种产科并发症,在发展中国家仍然是临床难题和广泛的公共卫生问题。目的:本研究旨在确定位于埃塞俄比亚西部的Nekemte转诊医院子宫破裂的程度、易感因素、母体和胎儿结局以及子宫破裂的手术选择。方法:对2015年7月至2016年7月在该院妇产科病房就诊的54例子宫破裂产妇和108例因机械原因或既往疤痕行剖宫产的产妇进行病例对照研究。通过查阅医疗记录从两组中收集数据。使用Statistical Package for Social Sciences windows version 20进行数据分析。采用比值比(OR)和95%CI评价子宫破裂与不同因素的相关性。结果:研究期间共分娩3,808例。阴道分娩3206例,剖宫产548例,子宫破裂54例。这使得70.5次分娩中有1次发生子宫破裂。大多数(87%)子宫破裂发生在无瘢痕子宫。子宫破裂的易感因素为胎次≥5次(OR=4.37, 95% CI: 1.05, 18.23)、缺乏产前护理(OR=7, 95% CI: 1.81, 27.02)、缺乏正规教育(OR=2.38, 95% CI: 1.08, 5.26)、家庭收入低于100美元(OR= 14.08, 95% CI: 3.25, 62.5)、以前在家分娩(OR=9.10, 95% CI: 3.92, 21.11)、以及在保健中心或私人诊所进行产前随访(OR=24.14, 95% CI: 5.60, 104.15)。与剖宫产分娩的母亲相比,子宫破裂导致的产妇死亡率(1.85%比0%)和新生儿死亡率(96.3%比3.7%)更高。结论:研究区子宫破裂程度高。它携带更多的产妇和围产期并发症。有许多可改变的诱发因素。

Background: Substance usage among youths is becoming a great problem worldwide, particularly in college and university students. Khat is one of the most frequently used substances among these groups of population. Khat chewing has serious health, social and economic consequences. However, in our setting the magnitude, pattern and factors contributing to the use of Khat is not well addressed. Therefore, this study was conducted to assess the prevalence, pattern and associated factors of Khat chewing among Debre Berhan University students in Ethiopia.Methods: This cross-sectional study was design to quantify the mastication of khat and identify socio demographic, behavioral and social factors among undergraduate students. Data was collected through structured, self-administered and pre-tested questionnaire. Stratified random sampling was used to recruit 406 students. Bivariable and multivariable logistic regression analyses were fitted via SPSS statistical software package to identify associated factors of khat chewing.Results: The life time and current prevalence of khat chewing were estimated to be 20.1% and 12.2%, respectively. Out of ever chewers, 68 (84%) were in the age group of 18-24 years and 62 (76.5%) were male. The most common reasons to chew khat were for examination preparation (41.9%) followed by socialization (38.3%). Significant association was observed between khat chewing and family members chewing khat (AOR = 6.26; 95% CI: 2.67, 14.72), friends chewing khat (AOR = 6.89; 95% CI: 3.71, 14.80) and use of alcohol (AOR = 2.50; 95% CI: 1.36, 4.60).Conclusion: The prevalence of khat chewing in this study was significantly higher when compared to some previous studies done in Addis Ababa University. The pattern of khat chewing among university students was not restricted by social regulation mechanisms, and even, it seems a social norm. Therefore, teachers in high schools, colleges and instructors in university should follow their students’ substance use behavior including khat and need to counsel those students who are at risk of substance use. Moreover, families ought to be a role model for their children by avoiding risk behaviors.
背景:青少年的药物使用正在成为一个世界性的大问题,特别是在大学生中。阿拉伯茶是这些人群中最常用的物质之一。咀嚼阿拉伯茶具有严重的健康、社会和经济后果。然而,在我们的设定中,影响阿拉伯茶使用的幅度、模式和因素并没有得到很好的解决。因此,本研究旨在评估埃塞俄比亚Debre Berhan大学学生咀嚼阿拉伯茶的患病率、模式和相关因素。方法:采用横断面研究的方法,对大学生咀嚼阿拉伯茶的情况进行定量分析,并对影响大学生咀嚼阿拉伯茶的社会人口学、行为和社会因素进行分析。数据通过结构化、自我管理和预先测试的问卷收集。采用分层随机抽样方法,共招收406名学生。采用SPSS统计软件包进行双变量和多变量logistic回归分析,确定咀嚼阿拉伯茶的相关因素。结果:咀嚼阿拉伯茶的寿命和当前流行率分别为20.1%和12.2%。在所有咀嚼者中,68人(84%)年龄在18-24岁之间,62人(76.5%)为男性。咀嚼阿拉伯茶最常见的原因是考试准备(41.9%),其次是社交(38.3%)。咀嚼阿拉伯茶与家庭成员咀嚼阿拉伯茶有显著相关性(AOR = 6.26;95% CI: 2.67, 14.72),朋友咀嚼阿拉伯茶(AOR = 6.89;95% CI: 3.71, 14.80)和酒精使用(AOR = 2.50;95% ci: 1.36, 4.60)。结论:与之前在亚的斯亚贝巴大学进行的一些研究相比,本研究中阿拉伯茶咀嚼的患病率明显更高。大学生咀嚼阿拉伯茶的模式不受社会调节机制的限制,甚至似乎是一种社会规范。因此,高中教师、大学教师和大学教师都应该关注学生的物质使用行为,包括阿拉伯茶,并对有物质使用风险的学生进行咨询。此外,家庭应该通过避免危险行为成为孩子的榜样。
