Cadmium, a deleterious heavy metal that pervades the environment, has the potential to accumulate in the body and cause health complications. In the domain of traditional medicine, medicinal plants have been employed to combat the toxicity of heavy metals and treating of many diseases in traditional medicine. Aim: To access the protective impact of Annona muricata seed extract on cadmium-triggered neurotoxicity in the cerebellum of albino wistarrat. Place of Study: Department of Anatomy, Faculty of Basic Medical Sciences Olabisi Onabanjo University, Ogun State between June 2022 and June 2023 METHODOLOGY: After a period of 14 days of acclimatization, 40 healthy male wistar rats were randomly allocated to four groups, group1(2ml/kg of distilled water), group2 cadmium only(2g/kg SC), group3 (2g/kg cadmium + 100mg/kg extract of Annona muricata) and group4(2g/kg cadmium + 200mg/kg extract of Annona muricata) The rats were subjected to cadmium subcutaneously followed by the oral administration of aqueous seed extract of Annona Muricata for fifteen consecutive days. Results: The impact of the extract on antioxidant enzymes activities of the cerebellum, cerebellar weight, as well as the histology of the cerebellum were scrutinized. The data revealed that the aqueous seed extract of Annona muricata, in a dose-dependent manner, augmented the levels of superoxide dismutase (SOD) (P=0.005) and catalase (CAT) (P=0.027) in contrast to the cadmium-only group. The relative weight of the cerebellum exhibited a significant increasein the treated groups compared to the cadmium-only group. The histology of the cerebellum delineated pathological changes arising from the exposure to cadmium, while Annona muricata brought about regenerative changes. Conclusion:  In summary, the study posits that owing to the presence of phytochemicals in Annona muricata aqueous seed extract, it was efficacious in mitigating the neurotoxicity induced by cadmium in the cerebellum of male rats.
镉是一种弥漫于环境中的有害重金属,有可能在人体内蓄积并引起健康并发症。在传统医学领域,药用植物被用来对抗重金属的毒性和治疗多种疾病。研究目的:了解鼠尾草种子提取物对镉引发的白化疣猪小脑神经毒性的保护作用。研究地点奥贡州奥拉比西-奥纳班乔大学基础医学院解剖学系,2022 年 6 月至 2023 年 6 月:经过 14 天的适应期后,40 只健康雄性 Wistar 大鼠被随机分配到四组,第一组(2 毫升/千克蒸馏水)、第二组(仅镉,2 克/千克 SC)、第三组(2 克/千克镉 + 100 毫克/千克鼠李子提取物)和第四组(2 克/千克镉 + 200 毫克/千克鼠李子提取物)。研究结果研究了提取物对小脑抗氧化酶活性、小脑重量以及小脑组织学的影响。数据显示,与纯镉组相比,鼠尾草种子水提取物以剂量依赖的方式提高了超氧化物歧化酶(SOD)(P=0.005)和过氧化氢酶(CAT)(P=0.027)的水平。与纯镉组相比,治疗组的小脑相对重量显著增加。小脑组织学显示,镉暴露引起了病理变化,而鼠李子则带来了再生变化。结论 综上所述,该研究认为,由于鼠李子水提取物中含有植物化学物质,因此能有效减轻镉对雄性大鼠小脑造成的神经毒性。

Background: Deficiencies of micronutrients (especially vitamins C, A, and E) during intra-uterine life have been linked with the possibility of increased risk of some diseases (e.g. cardiovascular disease and type 2 diabetes) in adulthood. Aims: Therefore, it becomes expedient that persistent and vigorous attention be paid to maternal vitamin status during gestation. Methodology: This is a cross-sectional comparative study carried out at maternity centres in Osogbo Local Government. Forty women who were at least 29 weeks of gestation and 40 apparently healthy women, age-matched, non-pregnant constituted the test and control groups respectively. Blood was obtained through an ante-cubital vein, centrifuged and used for vitamin estimations (High-Performance Liquid Chromatography). Birth weight and neonatal mortality ratio were the birth outcomes that were obtained. Data analysis was by Student’s t-test and Pearson’s correlation coefficient. P≤0.05 was considered significant. Results: Serum status of vitamins A (2.68±3.88 µg/dL); C (0.95±0.44 mg/dL); and E (0.67±0.04 mg/dL) were significantly lower at third trimester compared with the corresponding values of 6.98±1.26 µg/dL; 2.99±0.11 mg/dL; and 1.66±0.08 mg/dL among non-pregnant control. There were significant adverse pregnancy outcomes as signified by 10% stillbirths. In addition, low birth weight (1.5-2.4 kg) was observed among approximately 50% of the babies but no correlation was observed except between vitamins C and E. Conclusions: The results of this study revealed that among Nigerian pregnant women, there are risks of abnormal birth outcomes and low levels of vitamin A, C, and E. Aside depletions in vitamin C and E, the results of the study (r= .376; p= .020) suggest possible metabolic interaction between both.
背景:宫内缺乏微量营养素(尤其是维生素 C、A 和 E)可能会增加成年后罹患某些疾病(如心血管疾病和 2 型糖尿病)的风险。目的:因此,有必要对妊娠期母体的维生素状况给予持续而有力的关注。研究方法这是一项横断面比较研究,在奥索博地方政府的产科中心进行。40 名至少妊娠 29 周的妇女和 40 名明显健康、年龄匹配的非孕妇分别组成试验组和对照组。通过胫前静脉采集血液,离心后用于维生素估算(高效液相色谱法)。出生体重和新生儿死亡率是得出的出生结果。数据分析采用学生 t 检验和皮尔逊相关系数。P≤0.05 为差异显著。结果血清中维生素 A(2.68±3.88 µg/dL)、维生素 C(0.95±0.44 mg/dL)和维生素 E(0.67±0.04 mg/dL)的含量在妊娠三个月时明显低于非妊娠对照组的相应值:6.98±1.26 µg/dL;2.99±0.11 mg/dL;1.66±0.08 mg/dL。10%的死胎率表明存在严重的不良妊娠结局。此外,约 50%的婴儿出生体重偏低(1.5-2.4 千克),但除维生素 C 和 E 外,未发现其他相关性:除了维生素 C 和 E 的消耗外,研究结果(r= 0.376;p= 0.020)表明两者之间可能存在新陈代谢相互作用。

Aim: Artemether is the main component of the artemisinin-based combination therapy (ACT), used in the management of malaria infection caused by Plasmodium falciparum. Hence, its stability and conformation to pharmacopeia standards are necessary for use. The study aimed to review the first-order derivative spectrophotometric method for simultaneous estimation of artemether and its derivatives in pure and combined formulations, and their stability profiles, then develop a simple, precise, and fast technique for their rapid physicochemical analysis. Methodology: Thin-layer chromatographic (TLC) Fingerprinting principles were used in the analysis. Artemether and its derivatives were spotted on the TLC chromatograms after adding 25 mL of the suspension to a mixture of 100 mL of distilled water and 4 mL of NaOH, extracting the mixture with 60 mL of dichloromethane (DCM), drying, and sonicating the residue with 20 mL of the solvent. It was centrifuged, and the clear supernatant was spotted on the TLC plates. Results: The color test results revealed the presence of the artemether compound in the reference standard as well as the six brands of suspensions (A, B, C, D, E, and F) utilized in the study. Artemether melting point was obtained between 86 - 89 °C; within the International Pharmacopeia specified range. The chromatograms of Artemether and derivatives showed Rf values of 0.25 (impurity A), 0.3 (artenimol impurity B), 0.35 (impurity C), 0.4 (α-artemether: impurity D), and 0.55 (artemether). Conclusion: The devised method can be applied to the routine quality control analysis of artemether-lumefantrine suspension in addition to existing analytical techniques.
目的:蒿甲醚是青蒿素类复方疗法(ACT)的主要成分,用于治疗由恶性疟原虫引起的疟疾感染。因此,其稳定性和符合药典标准是使用的必要条件。本研究旨在回顾一阶导数分光光度法,用于同时估算纯制剂和复方制剂中的蒿甲醚及其衍生物,以及它们的稳定性曲线,然后开发一种简单、精确、快速的理化分析技术。 方法:采用薄层色谱(TLC)指纹图谱原理进行分析。在 100 毫升蒸馏水和 4 毫升 NaOH 的混合物中加入 25 毫升蒿甲醚及其衍生物悬浮液,用 60 毫升二氯甲烷(DCM)萃取混合物,干燥,用 20 毫升溶剂超声处理残留物,然后在 TLC 色谱图上点样。离心,将透明上清液点在 TLC 板上。 结果:颜色测试结果表明,在标准品和研究中使用的六种品牌悬浮液(A、B、C、D、E 和 F)中都含有蒿甲醚化合物。蒿甲醚的熔点在 86 - 89 °C 之间,在国际药典规定的范围内。蒿甲醚及其衍生物的色谱图显示 Rf 值分别为 0.25(杂质 A)、0.3(蒿甲醚杂质 B)、0.35(杂质 C)、0.4(α-蒿甲醚:杂质 D)和 0.55(蒿甲醚)。 结论除现有的分析技术外,所设计的方法还可用于蒿甲醚-本芴醇混悬液的常规质量控制分析。

Background: Chronic illnesses often affect grown-ups over 60 years of age, leading to inadequate and impecunious medication adherence, which increases the risk of bleakness, hospitalization, and mortality, despite the irrefutably factual benefits of certain medications.Aim and Objectives: To appraise the degree of drug intricacy in older patients with chronic diseases and to break down the factors impacting drug adherence among them.Methodology: A 10-month study involving 676 patients was carried out at the general medicine department of a tertiary hospital. Information was gathered for the study using the Morisky Medication Adherence Scale (MMAS) and the Medicine Regimen Complexity Index (MRCI).Results: A sample size of 676 on the whole, with 393 male patients surmounting 283 female patients. The level of intricacy was higher for the larger part of prescriptions. On the off chance that around 645 patients were prescribed more than 5 drugs. The greater part of the populace has shown good adherence (59%), trailed by moderate adherence (23%), and ultimately low adherence (18%). The intricacy of the prescription was recognized as the essential driver of non-adherence in 314 patients, and upon analyzing the responses from MRCI and MMAS scores, it was found that 156 patients on less complicated regimens exhibited moderate and 399 patients had great adherence among the total populace.Conclusion: To further develop drug adherence in more seasoned adults, doctors ought to consider medicine class numbers, high-risk prescriptions, and multi-layered systems, including age-related, natural, and social variables.
背景:慢性疾病经常影响 60 岁以上的老年人,导致他们服药不充分和不严格,从而增加了凄凉、住院和死亡的风险,尽管某些药物的益处是无可辩驳的事实:评估老年慢性病患者的用药复杂程度,并分析影响他们坚持用药的因素:一家三级医院的全科医学科开展了一项为期 10 个月的研究,共有 676 名患者参与。研究采用莫里斯基用药依从性量表(MMAS)和用药方案复杂性指数(MRCI)收集信息:总体样本量为 676 人,其中男性患者 393 人,女性患者 283 人。大部分处方的复杂程度较高。约有 645 名患者处方的药物超过 5 种。大部分人的用药依从性良好(59%),其次是中等依从性(23%),最后是低依从性(18%)。处方的复杂性被认为是导致 314 名患者不坚持用药的主要原因,在对 MRCI 和 MMAS 评分的反应进行分析后发现,在所有患者中,156 名接受较不复杂治疗方案的患者表现出中度依从性,399 名患者表现出高度依从性:结论:为了进一步提高老年人的用药依从性,医生应该考虑药品等级数量、高风险处方以及多层次系统,包括与年龄相关的、自然的和社会的变量。

Aims: Coula edulis Baill., (Olacaceae) is a non-lignified forest product not well known and widely used in sub-Saharan Africa as a phytomedicine or food additive. However, the toxicity of this plant remains unknown. This study aimed to assess the safety of the ethanolic extract of C. edulis stem bark (CEE). Study Design:  Pharmacological study. Place and Duration of Study: Laboratory of Nutrition and Nutritional Biochemistry, Department of Biochemistry, University of Yaounde 1 (Cameroon), between June 2018 and July 2022. Methodology: Studies on the assessment of acute and subchronic toxicity were carried out by guidelines 423 of the Organization for Economic Co-operation and Development (OECD). Subacute toxicity of the sample was assessed over 28 days using repeated doses by OECD Guideline 407. Results: No cases of death and clinical signs of toxicity were observed in the treated rats, suggesting that the LD50 of C. edulis ethanolic extract is greater than 2000 mg/kg bw. Regarding the subacute toxicity study, the administration of CEE also did not result in any changes in the course of body weight. Only a significant decrease in the relative weight of the ovaries in females at the highest dose of 600 mg/kg was observed. In males and females, CEE did not affect lipid profile markers or transaminase levels (AST, ALT). In addition, a small but non-significant (p> 0.05) increase in creatinine was observed without kidney dysfunction. In males, CEE induced an increase in mean corpuscular volume number at 600 mg/kg, while at the same time, mean corpuscular hemoglobin concentration decreased at the 300 mg/kg dose. In females, a significant increase in the number of monocytes, red blood cells, and hemoglobin level were observed. No difference in the levels of urea, glucose, and lipid markers was observed nor histological changes in the organs studied. Conclusion: As would be expected, exposure to CEE did not cause significant toxic effects in treated rats. Therefore, this plant extract can be safely recommended for therapeutic use.
目的:库拉·埃利斯·贝尔。(Olacaceae)是一种非木质化的森林产品,在撒哈拉以南非洲不为人所知,但被广泛用作植物药或食品添加剂。然而,这种植物的毒性仍然未知。本研究旨在评价毛竹茎皮乙醇提取物(CEE)的安全性。研究设计:药理学研究。学习地点和时间:喀麦隆雅温得第一大学生物化学系营养与营养生物化学实验室,2018年6月至2022年7月。方法:关于急性和亚慢性毒性评估的研究是根据经济合作与发展组织(经合组织)准则423进行的。根据经合组织指南407,在28天内使用重复剂量评估了样品的亚急性毒性。结果:治疗大鼠未见死亡及临床毒性症状,提示毛竹醇提物LD50 > 2000 mg/kg bw。在亚急性毒性研究中,施用CEE也没有导致体重过程的任何变化。在最高剂量为600 mg/kg时,只观察到雌性卵巢的相对重量有显著下降。在男性和女性中,CEE不影响血脂标记物或转氨酶水平(AST, ALT)。此外,肌酸酐虽有小幅升高,但不显著(p> 0.05),未见肾功能不全。在雄性小鼠中,CEE在600 mg/kg剂量下引起平均红细胞体积数增加,同时在300 mg/kg剂量下引起平均红细胞血红蛋白浓度下降。在女性中,观察到单核细胞数量、红细胞数量和血红蛋白水平显著增加。尿素、葡萄糖和脂质标志物的水平没有差异,所研究的器官也没有组织学变化。结论:正如预期的那样,暴露于CEE并没有对治疗大鼠造成明显的毒性作用。因此,这种植物提取物可以安全地推荐用于治疗用途。

Subacute toxicity of the sample was assessed over 28 days using repeated doses by OECD Guideline 407. \u0000Results: No cases of death and clinical signs of toxicity were observed in the treated rats, suggesting that the LD50 of C. edulis ethanolic extract is greater than 2000 mg/kg bw. Regarding the subacute toxicity study, the administration of CEE also did not result in any changes in the course of body weight. Only a significant decrease in the relative weight of the ovaries in females at the highest dose of 600 mg/kg was observed. In males and females, CEE did not affect lipid profile markers or transaminase levels (AST, ALT). In addition, a small but non-significant (p> 0.05) increase in creatinine was observed without kidney dysfunction. In males, CEE induced an increase in mean corpuscular volume number at 600 mg/kg, while at the same time, mean corpuscular hemoglobin concentration decreased at the 300 mg/kg dose. In females, a significant increase in the number of monocytes, red blood cells, and hemoglobin level were observed. No difference in the levels of urea, glucose, and lipid markers was observed nor histological changes in the organs studied. \u0000Conclusion: As would be expected, exposure to CEE did not cause significant toxic effects in treated rats. Therefore, this plant extract can be safely recommended for therapeutic use.","PeriodicalId":8536,"journal":{"name":"Asian Journal of Research in Medical and Pharmaceutical Sciences","volume":"125 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138599230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aims: The aim of this research is to study the efficacy of intranasal administration of 0.9% saline solution in patients with acute viral rhinitis and a history of Rhinitis medicamentosa. Materials and Methods: The study included 96 patients with a confirmed diagnosis of acute viral rhinitis and a history of Rhinitis medicamentosa. All patients were equally randomized to two groups. In both groups, patients were treated according to the European Position Paper on Rhinosinusitis and Nasal Polyps with nasal decongestants (oxymetazoline), but in Group 2, the treatment regimen was supplemented with topical use of 0.9% saline solution. Local TNF-α and IL-1β levels were determined in all patients on Days 1, 5, and 10. In addition, on the next day after oxymetazoline withdrawal, a Nasal airway resistance was measured in all patients using active posterior rhinomanometry. Results: The duration of rhinorrhea and nasal congestion and, respectively, the duration of oxymetazoline administration significantly differed between the groups (p<0.001) and was 7.9±1.1 days for Group 1 and 4.7±0.9 days for Group 2. In general, the dynamics of changes in local TNF-α and IL-1β levels in both groups was similar. Throughout the study, there was a progressive decrease in both inflammatory mediators, with faster changes occurring in Group 2. A strong positive correlation (rs=0.89; p<0.001) between TNF-α and IL-1β levels was established. According to the results of active posterior rhinomanometry on the day following oxymetazoline withdrawal, Nasal airway resistance was significantly higher in Group 1 (p<0.001), which indicates the presence of difficulty breathing in patients of this group. In addition, patient examination showed that manifestations of Rhinitis medicamentosa occurred in 3 (6.25%) patients of Group 1 and in 17 (35.42%) patients of Group 2. Differences between the groups were significant (p<0.01). Conclusion: The use of topical nasal decongestants, in particular oxymetazoline, in patients with acute viral rhinitis and a history of Rhinitis medicamentosa for more than 7 days has a potential risk of development of a recurrence of Rhinitis medicamentosa. Supplementing the treatment regimen for acute viral rhinitis with the topical use of 0.9% saline solution reduces the duration of treatment and the use of topical decongestants, and therefore prevents the recurrence of Rhinitis medicamentosa.
目的:本研究旨在探讨急性病毒性鼻炎和药物性鼻炎患者鼻内注射 0.9% 生理盐水的疗效。 材料与方法:研究对象包括 96 名确诊为急性病毒性鼻炎并有药物性鼻炎病史的患者。所有患者随机分为两组。两组患者均按照《欧洲鼻炎和鼻息肉立场文件》使用鼻腔减充血剂(奥美沙唑啉)进行治疗,但在第 2 组中,治疗方案辅以局部使用 0.9% 生理盐水溶液。在第 1、5 和 10 天测定所有患者的局部 TNF-α 和 IL-1β 水平。此外,在停用羟甲唑啉后的第二天,使用主动后鼻哮喘测量仪测量了所有患者的鼻气道阻力。 结果显示总体而言,两组患者局部 TNF-α 和 IL-1β 水平的变化动态相似。在整个研究过程中,这两种炎症介质都在逐渐减少,而第 2 组的变化更快。TNF-α和IL-1β水平之间存在很强的正相关性(rs=0.89;p<0.001)。根据停用羟甲唑啉次日的活动后鼻测量结果,第 1 组患者的鼻气道阻力明显增大(p<0.001),这表明该组患者存在呼吸困难。此外,患者检查显示,第 1 组有 3 例(6.25%)患者出现药物性鼻炎,第 2 组有 17 例(35.42%)患者出现药物性鼻炎。组间差异显著(P<0.01)。 结论急性病毒性鼻炎和药物性鼻炎病史超过 7 天的患者使用局部鼻腔减充血剂,尤其是奥美沙唑啉,有可能导致药物性鼻炎复发。在急性病毒性鼻炎的治疗方案中辅以局部使用 0.9%生理盐水溶液,可以缩短治疗时间,减少局部减充血剂的使用,从而防止药物性鼻炎复发。

Generalities: Cola lateritia (C. lateritia) is an under-valorized (neglected and unutilized) plant traditionally used in certain Cameroonian villages as medicine to manage certain diseases. The present work aimed to assess the phytochemical composition and the antioxidant potential of different parts of C. lateritia fruits. Methods: The fresh fruits of C. lateritia were purchased in October 2022 at Mfoundi-Market (Yaoundé 5, Centre Region of Cameroon), washed, sliced, dried, and powdered before being extracted with distilled water for the aqueous extract (AE) and ethanol/distilled water (70:30, v/v) for the hydro ethanolic extract (HEE). The bioactive compounds (polyphenols, saponins, tannins, flavonoids, and alkaloids) of the different extracts of fruit were quantified using standard methods. The Antioxidant potential of the different extracts was assessed using various methods [scavenging of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals, Total Antioxidant Capacity (TAC), and Ferric Reducing Antioxidant Power (FRAP)]. Results: The results indicated that the different extracts of C. lateritia fruit contain phytochemicals [polyphenols, flavonoids, tannins, saponins and alkaloids]. The AE of the skin (AE-sCLf) presented the highest contents (590.33 µg CaE/g DM, 191.73 µg QE/g DM and 945.33 µg  SaE/g DM) for polyphenols, flavonoids and saponins respectively while, the AE of pulp  (AE-PCLf) showed the highest content in alkaloids (121.59 µg QiE/g DM). The lowest tannin content was also reported in the AE of pulp (2.02 µg CaE/g DM). The extracts of C. lateritia exhibited a good radical scavenging activity of DPPH (with an inhibition percentage of 74.084 and 69.40% respectively for HEE-SCLf and AE-sCLf at 4 mg/mL). It’s reducing power towards molybdate and iron was concentration-dependent with values ranging from 0.116 to 2.393 μg AAE/g DM for TAC and from 0.0015 to 0.0032 μg AAE/g DM for FRAP, respectively. The highest iron-reducing activity of 941.410 µg AAE/g DM was observed with AE-sCLf at 4 mg/mL. The principal component analysis (PCA) showed a strong positive correlation between Bioactive and antioxidant activities. Conclusion: The C. lateritia fruit extracts (AE and HEE) contain various bioactive compounds, which exhibit good antioxidant activities through different mechanisms. It suggests C. lateritia as a potential nutritious food as well as functional food useful for the prevention of management of cardiometabolic diseases.
概况红叶高良姜(C. lateritia)是一种未被充分利用(被忽视和未被利用)的植物,喀麦隆的一些村庄传统上将其用作治疗某些疾病的药物。本研究旨在评估红叶高良姜果实不同部位的植物化学成分和抗氧化潜力。研究方法2022年10月在Mfoundi-Market(喀麦隆中部大区雅温得5区)购买了红叶石楠的新鲜果实,将其洗净、切片、烘干并制成粉末,然后用蒸馏水提取水提取物(AE),用乙醇/蒸馏水(70:30, v/v)提取水乙醇提取物(HEE)。采用标准方法对水果不同提取物中的生物活性化合物(多酚、皂苷、单宁、黄酮类和生物碱)进行了定量。采用多种方法评估了不同提取物的抗氧化潜力[清除 2,2-二苯基-1-苦基肼(DPPH)自由基、总抗氧化能力(TAC)和铁还原抗氧化能力(FRAP)]。结果表明结果表明,C. lateritia 果实的不同提取物含有植物化学物质 [多酚、类黄酮、单宁、皂苷和生物碱]。果皮提取物(AE-sCLf)的多酚、类黄酮和皂苷含量最高(分别为 590.33 µg CaE/g DM、191.73 µg QE/g DM 和 945.33 µg SaE/g DM),而果肉提取物(AE-PCLf)的生物碱含量最高(121.59 µg QiE/g DM)。果肉 AE 中的单宁含量也最低(2.02 µg CaE/g DM)。C. lateritia 的提取物具有良好的 DPPH 自由基清除活性(在 4 毫克/毫升的浓度下,HEE-SCLf 和 AE-sCLf 的抑制率分别为 74.084% 和 69.40%)。它对钼酸盐和铁的还原力与浓度有关,对 TAC 的还原力值为 0.116 至 2.393 μg AAE/g DM,对 FRAP 的还原力值为 0.0015 至 0.0032 μg AAE/g DM。浓度为 4 mg/mL 的 AE-sCLf 的铁还原活性最高,达到 941.410 µg AAE/g DM。主成分分析(PCA)显示,生物活性和抗氧化活性之间存在很强的正相关性。结论C. lateritia 果实提取物(AE 和 HEE)含有多种生物活性化合物,它们通过不同的机制表现出良好的抗氧化活性。这表明红叶石蒜是一种潜在的营养食品和功能食品,可用于预防和治疗心脏代谢疾病。

The objective of the present study is to evaluate anti-biofilm effect of the water soluble plant extracts such Coccinia grandis, Terminalia arjuna, Centella asiatica against Salmonella enterica and Staphylococcus aureus biofilm. Crude water soluble extracts of respective plants with different concentration was evaluated against biofilm adopting glass tube. Then washed with crystal violet dye and PBS buffer for observing the ring formation. Biofilm inhibition study revealed water soluble plant extracts inhibited biofilm formation. In our experiment we found that the plant extracts Coccinia grandis, Terminalia arjuna & Centella asiatica gave excellent result for the reduction of biofilm of Salmonella enteric & Staphylococcus aureus. Water soluble Coccinia grandis extract is very effective for biofilm reduction than alcoholic C. grandis extracts. We measured the antiplantonic effect of these extracts by including the extracts into the nutrient agar media that containing respective organism by creating the hole into the plate then observed the result after 24-hour incubation. We also measured minimum inhibition concentration of these extracts through spectrophotometer with the help of the nutrient broth media. Bacterial motality was tested in petri plates with semi-solid medium (LB+0.4% agar) containing plant extracts and culture were inoculated in the center of the plate. This research will be very beneficial for us to reduce the pathogenic S, aureus & S. enterica biofilm by natural source especially plant extracts.

Aim: To assess the push and pull factors associated with the retention of health workers in a district in Ghana. Study Design: This study was an analytical cross-sectional study using quantitative methods in the collection of data. Place and Duration of Study: Komenda-Edina-Eguafo-Abirem District of the Central Region of Ghana in October 2022. Methodology: A structured self-administered questionnaire was used to obtain data from 282 health workers who were consecutively selected from various health facilities in the study. The data collected was cleaned and analyzed using the statistical software STATA version 15. Descriptive statistics were presented in tables and graphs. A Chi-square test and multiple logistic regression analysis were used to assess the association between dependent and independent variables. The significance of association was set at P<0.05 at a 95% confidence interval. Results: Overall, 22.0% of the health workers intended to stay at their current organization. Logistic regression analysis predicted that age more than 35 years (AOR: 3.4, CI: 1.025 -11.283, P = .046) and sex - females (AOR: 0.56, CI: 0.016 - 0.223, P = .001) were significantly associated with retention. Institutional factors like lack of supervision of work (AOR: 0.508, CI: 0.176 – 1.472, P = .021), lack of in-service training (AOR:0.045, CI: 0.010 - 0.193, P = .001), inadequate management support (AOR: 0.288, CI: 0.109 – 0.764, P = .012), and poor career progression (AOR: 0.472, CI: 0.019 - 1.873, P = .028) significantly reduced the likelihood of staying. Community factors like the absence of family (AOR: 0.138, CI: 0.051 – 0.376, P = .001) and the absence of alternative jobs (AOR: 0.051, CI: 0.006 – 0.459, P = .008) also negatively predicted retention. Conclusion: Only a small proportion of health workers in the district intended to stay. Factors related to retention were predominantly organizational like career progression, management support, and incentives.
目的:评估与加纳某地区卫生工作者留用相关的推拉因素。 研究设计:本研究是一项采用定量方法收集数据的分析性横断面研究。 学习地点和时间:2022年10月加纳中部地区komenda - edna - eguafo - abirem地区。 方法:采用一份结构化的自我管理问卷,从282名卫生工作者那里获得数据,这些卫生工作者是在研究中连续从不同的卫生设施中选出的。使用统计软件STATA version 15对收集的数据进行清理和分析。描述性统计以表格和图表的形式呈现。采用卡方检验和多元逻辑回归分析来评估因变量和自变量之间的相关性。在95%的置信区间内,关联的显著性设置为P<0.05。& # x0D;结果:总体而言,22.0%的卫生工作者打算留在目前的机构。Logistic回归分析预测年龄大于35岁(AOR: 3.4, CI: 1.025 ~ 11.283, P = 0.046)和性别女性(AOR: 0.56, CI: 0.016 ~ 0.223, P = 0.001)与潴留显著相关。缺乏工作监督(AOR: 0.508, CI: 0.176 ~ 1.472, P = 0.021)、缺乏在职培训(AOR:0.045, CI: 0.010 ~ 0.193, P = 0.001)、管理支持不足(AOR: 0.288, CI: 0.109 ~ 0.764, P = 0.012)、职业发展不佳(AOR: 0.472, CI: 0.019 ~ 1.873, P = 0.028)等制度因素显著降低了员工留下来的可能性。社区因素如家庭缺失(AOR: 0.138, CI: 0.051 ~ 0.376, P = 0.001)和缺乏替代工作(AOR: 0.051, CI: 0.006 ~ 0.459, P = 0.008)对留任也有负相关预测。& # x0D;结论:该地区只有一小部分卫生工作者打算留下来。与留存率相关的因素主要是组织方面的,比如职业发展、管理支持和激励。

Logistic regression analysis predicted that age more than 35 years (AOR: 3.4, CI: 1.025 -11.283, P = .046) and sex - females (AOR: 0.56, CI: 0.016 - 0.223, P = .001) were significantly associated with retention. Institutional factors like lack of supervision of work (AOR: 0.508, CI: 0.176 – 1.472, P = .021), lack of in-service training (AOR:0.045, CI: 0.010 - 0.193, P = .001), inadequate management support (AOR: 0.288, CI: 0.109 – 0.764, P = .012), and poor career progression (AOR: 0.472, CI: 0.019 - 1.873, P = .028) significantly reduced the likelihood of staying. Community factors like the absence of family (AOR: 0.138, CI: 0.051 – 0.376, P = .001) and the absence of alternative jobs (AOR: 0.051, CI: 0.006 – 0.459, P = .008) also negatively predicted retention. &#x0D; Conclusion: Only a small proportion of health workers in the district intended to stay. Factors related to retention were predominantly organizational like career progression, management support, and incentives.","PeriodicalId":8536,"journal":{"name":"Asian Journal of Research in Medical and Pharmaceutical Sciences","volume":"31 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135820215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction: Neck imaging has always been a diagnostic challenge. High-resolution sonography being inexpensive and safe has become the initial investigation of choice for neck pathologies; it provides information regarding the origin and extent of the lesion. Computed tomography (CT) has a unique capacity for displaying soft tissue, bone and airway details and provides critical anatomical information about lesions involving the neck. This study aims to determine the role of USG and CT in neck masses for pre-operative characterization based on location, extent, morphological characteristics and enhancement pattern and to compare USG and CT findings with histopathological diagnosis. Material and Methods: A total number of 60 adult patients with suspected neck masses were studied in the department of Radiodiagnosis, SSIMS&RC, Davanagere and inputs from Dr. B. R. Ambedkar Medical College, Bengaluru over a period of 24 months. Ultrasound was done using GE Voluson E6 machine & Contrast enhanced CT was done using GE Revolution Multidetector CT scan machine. Post processing techniques (like volume rendered techniques) were applied wherever useful. Results: The findings on USG and CT were conclusive in nearly 90% of cases. Enhancement patterns and presence/absence of bony invasion were found to be more specific in differentiating benign/malignant nature. Conclusion: High-resolution sonography can be used as the first-line modality for evaluating cervical soft tissue masses, it helps the clinicians to characterize the lesion. Multi-detector computed tomography is a sensitive diagnostic tool for diagnosing neck masses and differentiating between benign and malignant lesions with high accuracy. The extent of pathology with local/ contiguous spread predicted by CT examination was conclusive. The overall findings suggest that MDCT and Ultrasound, when used in conjunction with pathological correlation, can be effective tools for accurately characterizing and diagnosing the neck masses.
颈部影像学诊断一直是一个挑战。高分辨率超声检查价格低廉且安全,已成为颈部病变的首选检查方法;它提供了关于病变的起源和范围的信息。计算机断层扫描(CT)具有显示软组织、骨骼和气道细节的独特能力,并提供涉及颈部病变的关键解剖学信息。本研究旨在根据颈部肿块的位置、范围、形态学特征和增强模式,确定USG和CT在术前诊断中的作用,并将USG和CT表现与组织病理学诊断进行比较。 材料和方法:在Davanagere SSIMS&RC放射诊断部和班加罗尔Dr. B. R. Ambedkar医学院,共研究了60例疑似颈部肿块的成年患者,为期24个月。超声采用GE Voluson E6超声仪;采用GE Revolution多层螺旋CT增强扫描机。后期处理技术(如体积渲染技术)被应用到任何有用的地方。 结果:近90%的病例超声和CT表现均为结论性。增强模式和有无骨侵犯在鉴别良/恶性方面更为特异。 结论:高分辨率超声可作为评价颈部软组织肿块的一线手段,有助于临床医生对病变的特征进行鉴别。多探测器计算机断层扫描是诊断颈部肿块和鉴别良恶性病变的灵敏诊断工具,准确度高。CT检查预测局部/连续扩散的病理程度是结论性的。总体结果表明,MDCT和超声,当结合病理相关性时,可以有效地准确描述和诊断颈部肿块。
