The entomofauna vector of rice yellow mottle virus was studied from June to September 2023 in the rainfed rice ecosystem of Maroua and in the main irrigated rice ecosystems of Yagoua and Maga in the Far North Region, Cameroon . Insect vector sampling was conducted in rainfed and irrigated rice fields every two weeks using a sweep net and a D-Vac (vacuum trap). From the samples obtained in the different rice-growing sites, the dominant structure of insect vectors of rice yellow mottle as well as their natural enemies was analyzed according to the phenology of rice. It appears from the inventory of insects in irrigated rice (Maga, Yagoua) and rainfed rice (Maroua) that this crop harbors many vectors of the rice yellow mottle virus. In the different rice-growing sites, we have numbers of vector insect individuals captured of 267, 286 and 385 respectively in Maroua (rainfed rice), Maga and Yagoua (irrigated rice). The vector insects captured are distributed as follows, eight species of vector insects in irrigated rice in Maga belonging to five families divided into three orders: Chnootriba similis (Coleoptera: Coccinellidae), Chaetocnema pulla (Coleoptera: Chrysomelidae), Locris rubra ( Hemiptera: Cicadellidae), Nephotettix nigropictus (Hemiptera: Cicadellidae), Sogatella furcifera (Hemiptera: Delphacidae), Cofana spectra (Hemiptera: Cicadellidae), Niparvata lugens (Hemiptera: Delphacidae) and Diopsis thoracica (Diptera: Diopsidae). In irrigated rice in Yagoua, eleven species of vector insects belonging to seven families divided into three orders were collected: Chnootriba similis (Coleoptera: Coccinellidae), Chaetocnema pulla (Coleoptera: Chrysomelidae), Locris rubra (Hemiptera: Cicadellidae), Nephotettix nigropictus (Hemiptera: Cicadellidae), Sogatella furcifera (Hemiptera: Delphacidae), Cofana spectra (Hemiptera: Cicadellidae), Recilia dorsalis (Hemiptera: Cicadellidae), Niparvata lugens (Hemiptera: Delphacidae), Leptocorisa oratorius (Hemiptera: Alydidae), Diploxys spp. (Hemiptera: Pentatomidae) and Diopsis thoracica (Diptera: Diopsidae). As for rainfed rice in Maroua, thirteen vector insect species belonging to seven families and three orders were collected: Chnootriba similis (Coleoptera: Coccinellidae), Chaetocnema pulla (Coleoptera: Chrysomelidae), Trichispa sericea (Coleoptera: Chrysomelidae), Locris rubra (Hemiptera: Cicadellidae), Nephotettix nigropictus (Hemiptera: Cicadellidae), Sogatella furcifera (Hemiptera: Delphacidae), Cofana spectra (Hemiptera: Cicadellidae), Recilia dorsalis (Hemiptera: Cicadellidae), Niparvata lugens (Hemiptera: Delphacidae) and Diopsis thoracica (Diptera: Diopsidae). These species proved to be particularly important by the size of their populations at the tillering stage of rice. The irrigated rice ecosystems of Yagoua and Maga are the most infested by insect vectors of rice yellow mottle virus and among these insect vectors Nephotettix nigropictus (Hemiptera: Cicadellidae) is the abundant species with 87 and 90
2023 年 6 月至 9 月,研究人员在喀麦隆远北地区马鲁阿的雨水灌溉水稻生态系统以及亚古阿和马加的主要灌溉水稻生态系统中研究了水稻黄斑病病毒的虫媒。每两周使用扫网和 D-Vac(真空诱捕器)在雨养和灌溉稻田进行一次虫媒采样。从不同水稻种植地获得的样本中,根据水稻的物候学分析了水稻黄斑病虫害昆虫媒介及其天敌的优势结构。从灌溉水稻(Maga、Yagoua)和雨水灌溉水稻(Maroua)的昆虫清单中可以看出,水稻黄斑病菌的传播媒介很多。在不同的水稻种植地,我们在马鲁阿(雨浇稻)、马加和亚古阿(灌溉稻)分别捕获了 267、286 和 385 头媒介昆虫。捕获的病媒昆虫分布如下:马加灌溉水稻中的病媒昆虫有 8 种,隶属于 5 个科,分为 3 个目:Chnootriba similis (Coleoptera: Coccinellidae)、Chaetocnema pulla (Coleoptera: Chrysomelidae)、Locris rubra (Hemiptera: Cicadellidae)、Nephotettix nigropictus (Hemiptera:(半翅目:蝉科)、Nephotettus nigropictus (半翅目:蝉科)、Sogatella furcifera (半翅目:双翅目)、Cofana spectra (半翅目:蝉科)、Niparvata lugens (半翅目:双翅目)和 Diopsis thoracica (双翅目:双翅目)。在 Yagoua 的灌溉水稻中,共收集到 11 种病媒昆虫,隶属于三个目中的七个科:Chnootriba similis (Coleoptera: Coccinellidae)、Chaetocnema pulla (Coleoptera: Chrysomelidae)、Locris rubra (Hemiptera: Cicadellidae)、Nephotettix nigropictus (Hemiptera: Cicadellidae)、Sogatella furcifera (Hemiptera. Delphacidae)、Coficia nigropictus (Hemiptera: Cicadellidae):Delphacidae), Cofana spectra (Hemiptera: Cicadellidae), Recilia dorsalis (Hemiptera: Cicadellidae), Niparvata lugens (Hemiptera: Delphacidae), Leptocorisa oratorius (Hemiptera: Alydidae), Diploxys spp.(半翅目:Pentatomidae) 和 Diopsis thoracica (双翅目:Diopsidae)。至于马鲁阿的雨养水稻,共收集到 13 种媒介昆虫,隶属于 7 科 3 目:Chnootriba similis (Coleoptera: Coccinellidae)、Chaetocnema pulla (Coleoptera: Chrysomelidae)、Trichispa sericea (Coleoptera: Chrysomelidae)、Locris rubra (Hemiptera: Cicadellidae)、Nephotettix nigropictus (Hemiptera:这些物种被证明尤为重要,其中包括:"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠"、"蝙蝠 "和 "蝙蝠"。这些物种在水稻分蘖期的种群规模证明了它们的重要性。Yagoua 和 Maga 的灌溉水稻生态系统受水稻黄斑病菌昆虫载体的侵扰最为严重,在这些昆虫载体中,Nephotettix nigropictus(半翅目:蝉科)是数量最多的物种,在 Maga 和 Yagoua 分别采集到 87 和 90 个个体。Nephotettix nigropictus(半翅目:蝉科)在水稻分蘖期被大量采集到。至于稻田中的天敌和寄生虫,有蜘蛛 Araneus sp.(鹤形目:Araneidae)、Tetragnatha sp.(鹤形目:Tetragnatidae)、Pardosa injucunda(鹤形目:Lyconidae)和瓢虫 Xanthadalia effusa(鞘翅目:Coccinellidae)作为天敌,Hydrellia griseola(双翅目:Ephydridae)、Bracon sp.(Hymenoptera: Braconidae), Xiphosomella sp. (Hymenoptera: Braconidae), Platygaster sp. (Hymenoptera: Platygasteridae) 为寄生虫。寄生种 Hydrellia griseola(双翅目:Ephydridae)和捕食种 Araneus sp.(鹤形目:Araneidae)是极北地区水稻生态系统中最丰富的天敌。

Introduction: Due to the very marked disparity in the adoption of continuous rotation and its perceived lack of use in developing countries, the present study aims to determine the factors preventing the adoption of continuous rotation in endodontic practice in Madagascar. Methods: This is a retrospective cross-sectional descriptive study conducted from November 2022 to October 2023, on 45 Odontostomatologists from the Haute Matsiatra region, selected on an exhaustive basis. Results: The study reported that no practitioner in the region practiced continuous rotation, mainly due to the high cost of equipment (63.6%), lack of practitioner training (63.6%) and limited knowledge of the technique (48.9%), the unavailability of equipment (50%), frequent power cuts (22.7%), the unprofitability of the technique (18.2%) and practitioners' lack of dexterity (4.5%). Conclusion: An in-depth study throughout Madagascar would be desirable to determine the prevalence of its use and assess the factors behind its inaccessibility.
引言:由于发展中国家在采用连续旋转方面存在着非常明显的差异,而且人们认为连续旋转在发展中国家缺乏应用,因此本研究旨在确定阻碍马达加斯加牙髓病学实践中采用连续旋转的因素。方法:这是一项回顾性横断面描述性研究,研究时间为 2022 年 11 月至 2023 年 10 月,研究对象是上马齐亚特拉(Haute Matsiatra)地区的 45 名牙髓科医生,他们都是经过严格筛选的。研究结果研究报告显示,该地区没有从业人员实行连续轮转,主要原因是设备价格昂贵(63.6%)、缺乏从业人员培训(63.6%)和技术知识有限(48.9%)、设备不可用(50%)、经常停电(22.7%)、技术无利可图(18.2%)和从业人员缺乏灵活性(4.5%)。结论最好在马达加斯加全国范围内进行深入研究,以确定该技术的使用普及率,并评估无法获得该技术背后的因素。

Musculoskeletal disorder (MSD) is a group of periarticular conditions affecting the soft and bony tissues of the limbs and back. Its prevalence is high among odontostomatologists, ranging from 60 to 90.3%. It is therefore a real source of concern and a public health problem. The aim of this study was therefore to describe the impacts and prevention of this disorder among odontostomatologists. This is a literature review study following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) method. The documentary search on scientific databases was carried out using the keywords TMS, odontostomatologists, ergonomics, prevention. The study included all articles on the impacts and prevention of MSDs among odontostomatologists published over the past 10 years from 2013 to 2023 written in French or English without restriction as to article type. Incomplete, irrelevant articles published in scientific conferences were excluded . The study analyzed 32 articles and showed that the main impacts of MSDs were pain (56.5%), self-medication (17.4%), reduced quality of work and working hours (17.4%), absenteeism and early retirement (13.0%). Prevention was based on the practice of good ergonomics (73.3%), the use of magnifying glasses (33.3%) and the practice of physical exercise after work (20%). Given these results, ongoing training in MSD prevention is essential to reduce or avoid its occurrence.
肌肉骨骼疾病(MSD)是一组影响四肢和背部软骨组织的关节周围疾病。它在口腔科医生中的发病率很高,从 60% 到 90.3% 不等。因此,这确实是一个令人担忧的公共卫生问题。因此,本研究的目的是描述这种疾病在口腔骨科医生中的影响和预防。这是一项文献综述研究,遵循 PRISMA(系统综述和元分析首选报告项目)方法。使用关键词 TMS、口腔医师、人体工程学、预防在科学数据库中进行了文献检索。该研究包括2013年至2023年过去10年间发表的所有有关口腔医师MSDs的影响和预防的法文或英文文章,文章类型不限。在科学会议上发表的不完整、不相关的文章被排除在外。研究分析了32篇文章,结果显示,MSDs的主要影响是疼痛(56.5%)、自行用药(17.4%)、工作质量和工作时间下降(17.4%)、旷工和提前退休(13.0%)。预防措施主要是采用良好的人体工程学(73.3%)、使用放大镜(33.3%)和下班后进行体育锻炼(20%)。鉴于这些结果,持续进行 MSD 预防培训对于减少或避免其发生至关重要。

This research was carried out to determine the formation brittleness and textural attributes of an Axx-Field in the Niger Delta Basin. Data available for this study were obtained from three wells (A11, A22 and A33). They were analyzed using Microsoft Excel after spurious values were removed. Two techniques (John Fuller and Plumb Bradford) were used to determine static young's modulus but only one is reported because after statistical analysis on both, the one reported was adequate for accurate outcomes although both approaches have low variance. The results indicates that the highest values of static and dynamic young's modulus are 2.05 x 1025N/m2 and 1.93 x 1010N/m2 respectively. The lowest values are 1.1 x 1024N/m2 and 8.5 x 109N/m2 respectively for well A11. The average values are 1.024 x 1025N/m2 and 5.25 x 1023N/m2 for this well. For well A22, the highest and lowest values of dynamic young’s modulus are 1.5848 x 1010N/m2 and 1.5726 x 1010N/m2 while those of static are correspondingly 1.47 x 1025N/m2 and 9.01 x 1014N/m2. Their average values are 1.5787 x 1010N/m2 and 7.35 x 1024N/m2 for dynamic and static young's moduli respectively. Also, for well A33, dynamic has the lowest value as 3.28 x 1010 N/m2; static has 8.36 x 1014N/m2 and their highest correspond to 2.04 x 1010N/m2 and 7.08 x 1025N/m2. The average value for this well are 2.66 x 1010N/m2 and 3.54 x 1025 N/m2 for dynamic and static respectively. The static Young's modulus results define the formation as brittle, whose environment is extremely poorly sorted, very fine skewed and very leptokurtic with low energy for well A11, very poorly sorted, fine skewed and platykurtic for well A22, extremely poorly sorted, very fine skewed and mesokurtic for well A33.
本研究旨在确定尼日尔三角洲盆地 Axx 油田的地层脆性和纹理属性。本研究的数据来自三口油井(A11、A22 和 A33)。在去除虚假值后,使用 Microsoft Excel 对数据进行了分析。使用了两种技术(John Fuller 和 Plumb Bradford)来确定静态青年模量,但只报告了其中一种,因为在对两种技术进行统计分析后,尽管两种方法的方差都很小,但报告的一种技术足以获得准确的结果。结果表明,静态和动态杨氏模量的最高值分别为 2.05 x 1025N/m2 和 1.93 x 1010N/m2。A11 井的最低值分别为 1.1 x 1024N/m2 和 8.5 x 109N/m2。该井的平均值分别为 1.024 x 1025N/m2 和 5.25 x 1023N/m2。在 A22 井中,动态青年模量的最高值和最低值分别为 1.5848 x 1010N/m2 和 1.5726 x 1010N/m2,而静态青年模量的最高值和最低值分别为 1.47 x 1025N/m2 和 9.01 x 1014N/m2。它们的平均值分别为 1.5787 x 1010N/m2 和 7.35 x 1024N/m2。此外,在 A33 井中,动态值最低,为 3.28 x 1010 N/m2;静态值为 8.36 x 1014 N/m2,它们的最高值分别为 2.04 x 1010 N/m2 和 7.08 x 1025N/m2。这口井的动态和静态平均值分别为 2.66 x 1010N/m2 和 3.54 x 1025N/m2。静态杨氏模量结果表明地层为脆性地层,A11 井的地层环境为极差分选、极细斜和低能量的极左曲地层;A22 井的地层环境为极差分选、细斜和板状曲地层;A33 井的地层环境为极差分选、极细斜和中曲地层。

Purpose: The purpose of this study was to investigate the feasibility of using the Winston-Lutz (WL) interchangeability with a Machine Performance Check-enhanced couch for pretreatment quality assurance (QA) of stereotactic radiotherapy (SRS) and stereotactic body radiation therapy (SBRT). The study employed the MPC with an electronic portal imaging device (EPID) to carry out geometric checks and verify the radiation isocenter. The isocenter size was assessed using the MultiMet cube and the MPC-enhanced couch module for SRS/SBRT pretreatment QA. Methods: The isocenter size of the MPC-enhanced couch module was compared to the WL measurements of the MultiMet cube. Measurements were taken at various gantry, collimator, and couch angles over a period of one month. The data from the cube were evaluated using PIPSRO and MultiMet (MMWL), including the offset targets. Various statistical tests were performed to evaluate the agreement, normality, separability, sensitivity, and specificity between the two methods. Results: The results showed isocenter sizes of 0.273 ± 0.065 mm, 0.293 ± 0.010 mm, and 0.209 ± 0.070 mm for PIPSPRO, MPC, and MMWL, respectively. The average bias was -0.0639 ± 0.1061 mm between MMWL and PIPSPRO, -0.0837 ± 0.0688 mm between MMWL and MPC, and 0.0198 ± 0.0696 mm between MPC and PIPSPRO. A Shapiro-Wilk test revealed no significant departure from normality for all tests and showed satisfactory discrimination through the area under the curve (AUC). A paired t-test analysis revealed a statistically significant difference between the mean isocenter size of the MPC and WL (MMPWL: t = 5.654, df = 29, p < 0.001; PIPSPRO: t = -1.483, DF = 29, p = 0.1488), and there was no significant difference within the WL test (t = 3.008, DF = 29, p = 0.0054). Conclusion: Despite the statistical test results, there was agreement between the MPC and WL radiation isocenter size that was within the requirement of the AAPM TG 142 tolerance (±1.0 mm). The MPC proved to be accurate, reproducible, and consistent throughout the measurements, making it an appropriate and effective pretreatment QA tool for SRS/SBRT.
目的:本研究旨在探讨将温斯顿-鲁兹(WL)互换性与机器性能检查增强型床用于立体定向放射治疗(SRS)和立体定向体放射治疗(SBRT)预处理质量保证(QA)的可行性。该研究使用带有电子门成像装置(EPID)的 MPC 来进行几何检查和验证辐射等中心。使用MultiMet立方体和MPC增强沙发模块对SRS/SBRT预处理质量保证的等中心尺寸进行评估。方法:将 MPC 增强沙发模块的等中心尺寸与 MultiMet 立方体的 WL 测量值进行比较。在一个月的时间内,以不同的龙门架、准直器和坐榻角度进行了测量。使用 PIPSRO 和 MultiMet (MMWL) 评估了立方体的数据,包括偏移目标。对两种方法的一致性、正态性、可分离性、灵敏度和特异性进行了各种统计检验。结果显示结果显示,PIPSPRO、MPC 和 MMWL 的等中心尺寸分别为 0.273 ± 0.065 毫米、0.293 ± 0.010 毫米和 0.209 ± 0.070 毫米。MMWL 和 PIPSPRO 之间的平均偏差为 -0.0639 ± 0.1061 毫米,MMWL 和 MPC 之间的平均偏差为 -0.0837 ± 0.0688 毫米,MPC 和 PIPSPRO 之间的平均偏差为 0.0198 ± 0.0696 毫米。Shapiro-Wilk 检验表明,所有测试均未明显偏离正态性,曲线下面积 (AUC) 显示出令人满意的分辨力。配对 t 检验分析表明,MPC 和 WL 的平均等中心尺寸之间存在显著差异(MMPWL:t = 5.654,df = 29,p < 0.001;PIPSPRO:t = -1.483,DF = 29,p = 0.1488),而 WL 检验没有显著差异(t = 3.008,DF = 29,p = 0.0054)。结论尽管统计测试结果存在差异,但 MPC 和 WL 辐射等中心尺寸之间的一致性符合 AAPM TG 142 公差要求(±1.0 毫米)。事实证明,MPC 在整个测量过程中都是准确、可重复和一致的,是 SRS/SBRT 适当而有效的预处理质量保证工具。

The present study evaluates the efficiency of the dry biomass of the microalgae Spirogyra porticalis and Nannochloropsis oculata for the removal of fenamiphos, imidacloprid, and oxamyl pesticides from water. The influence of incubation time, pesticide concentration, and algal biomass concentration on the degradation of pesticides were considered in the study. A rapid UV-Vis spectrophotometry method was developed and validated for the analysis and quantification of pesticides in the context of bioremediation with microalgae. The optimum conditions were obtained at 15 min, 50 mg/L pesticide concentration and 900 mg/L algal biomass with the response of 67.27% and 68.67 for fenamiphos by S. porticalis and N. oculata, respectively. For Imidacloprid, the optimum conditions were obtained at 15 min, 50 mg/L pesticide concentration and 900 mg/L algal biomass with the response of 28.20% and 35.55 for fenamiphos by S. porticalis and N. oculata, respectively. With the same, previse conditions the response of 65.71 and 81.31% for oxamyl by S. porticalis and N. oculata, respectively. This study confirmed that removing pesticides by the microalgae S. porticalis and N. oculata are both active and biomass of algae dependent. Consequently, these algae biomass exhibited a potential reduction of pesticides in contaminated water samples.​

The second section of manuscript should contain Abstract and Keywords. Abstract should be informative, self-explanatory and easy to understand. Plant parts have continued to attract attention in the global search for the treatment of many diseases affecting humans. Dennetia tripetala (mmimi) is a well-known spicy indigenous forest fruit from the family annonacea and has been found to contain lots of minerals, vitamins, alkaloids and trace elements which are of medicinal importance. This study investigated the effect of topical ripe and unripe Dennetia tripetala seed extracts on the intraocular pressure of albino Wistar rats. Fifteen healthy male albino Wistar rats were used for the study. The rats were randomly divided into 3 groups (A, B, C), each group consisting of 5 rats. Group A rats were treated with one drop of ripe seed extract in their right eye and one drop of Timolol eye drop in their left eye. Group B rats received one drop of unripe seed extract in their right eye and one drop of Timolol eye drop in their left eye. Group C rats served as control (received one drop of water in OD). The I0P of each rat was measured pre and post instillation of one drop volume of the solutions at 30 mins interval for 120 minutes. The findings showed peak reduction of IOP after 60 mins (6.02 mmHg, representing 31.2 % reduction) of instillation one drop volume of ripe D. tripetala seed extract and reverted towards baseline (19.16 mmhg). The peak effect of ripe D. tripetala was found to be statistically significant (P =4.558). Unlike ripe D. tripetala seed extract, the unripe extract induced consistent IOP reduction till 120 minutes (5 % after 30 minutes, 16.5 % after 60minutes and 17.9 % after 120 minutes) from the baseline (18.84 mmHg). The reduction in IOP after 60 minutes (P = .4145) and 120 minutes was statistically significant (P= 2.5448). When compared with Timolol, Timolol produced steady and highest IOP reduction (15 %, 23.5 %, and 33.3 % from the baseline) 30 minutes, 60 minutes and 120 minutes post instillation respectively. Topical administration of aqueous extract of ripe D. tripetala seed significantly reduced intraocular pressure in albino Wistar rats, suggesting anti-glaucoma effect of the extract.
第二部分稿件应包含摘要和关键词。摘要应该内容翔实,不言自明,易于理解。在全球寻求治疗影响人类的许多疾病的过程中,植物部分继续引起人们的注意。三瓣丹是番荔枝科的一种著名的本土辛辣森林水果,含有丰富的矿物质、维生素、生物碱和微量元素,具有重要的药用价值。研究了外用成熟和未成熟三瓣丹籽提取物对白化Wistar大鼠眼压的影响。15只健康雄性白化Wistar大鼠被用于研究。将大鼠随机分为A、B、C 3组,每组5只。A组大鼠右眼滴入成熟种子提取物1滴,左眼滴入替马洛尔滴眼液1滴。B组大鼠右眼滴生籽提取物1滴,左眼滴替莫洛尔滴眼液1滴。C组大鼠作为对照(OD滴1滴水)。每只大鼠滴注1滴体积的溶液前后,间隔30分钟测定I0P,持续120分钟。结果显示,滴注1滴成熟三瓣花种子提取物60分钟后IOP峰值降低(6.02 mmHg,降低31.2%),并恢复到基线水平(19.16 mmHg)。成熟三蹄草的峰值效应有统计学意义(P =4.558)。与成熟的三瓣花种子提取物不同,未成熟的提取物诱导的IOP从基线(18.84 mmHg)持续降低至120分钟(30分钟后降低5%,60分钟后降低16.5%,120分钟后降低17.9%)。60分钟后IOP降低(P= 0.4145), 120分钟后IOP降低有统计学意义(P= 2.5448)。与替莫洛尔相比,替莫洛尔在滴注后30分钟、60分钟和120分钟分别产生稳定和最高的IOP降低(比基线降低15%、23.5%和33.3%)。白化Wistar大鼠眼压明显降低,提示其具有抗青光眼作用。

Abstract should be informative, self-explanatory and easy to understand. Plant parts have continued to attract attention in the global search for the treatment of many diseases affecting humans. Dennetia tripetala (mmimi) is a well-known spicy indigenous forest fruit from the family annonacea and has been found to contain lots of minerals, vitamins, alkaloids and trace elements which are of medicinal importance. This study investigated the effect of topical ripe and unripe Dennetia tripetala seed extracts on the intraocular pressure of albino Wistar rats. Fifteen healthy male albino Wistar rats were used for the study. The rats were randomly divided into 3 groups (A, B, C), each group consisting of 5 rats. Group A rats were treated with one drop of ripe seed extract in their right eye and one drop of Timolol eye drop in their left eye. Group B rats received one drop of unripe seed extract in their right eye and one drop of Timolol eye drop in their left eye. Group C rats served as control (received one drop of water in OD). The I0P of each rat was measured pre and post instillation of one drop volume of the solutions at 30 mins interval for 120 minutes. The findings showed peak reduction of IOP after 60 mins (6.02 mmHg, representing 31.2 % reduction) of instillation one drop volume of ripe D. tripetala seed extract and reverted towards baseline (19.16 mmhg). The peak effect of ripe D. tripetala was found to be statistically significant (P =4.558). Unlike ripe D. tripetala seed extract, the unripe extract induced consistent IOP reduction till 120 minutes (5 % after 30 minutes, 16.5 % after 60minutes and 17.9 % after 120 minutes) from the baseline (18.84 mmHg). The reduction in IOP after 60 minutes (P = .4145) and 120 minutes was statistically significant (P= 2.5448). When compared with Timolol, Timolol produced steady and highest IOP reduction (15 %, 23.5 %, and 33.3 % from the baseline) 30 minutes, 60 minutes and 120 minutes post instillation respectively.
