This study was conducted in 2021 to study the impact of planting date on maize inbred lines and determine their accumulated growing degree units (GDU).The experiment was held at three agriculture research stations (Gemmeiza, Ismaelia and Sids) with RCBD of four replications. It was planned to provide also some insights to optimize maize production and mitigate the impact of climatic changes to all researchers in the scientific community. Three planting dates i.e. April 20th (early), May20th (optimal) and June 20th (moderately late) were applied to investigate their effect on number of days to 50% tasselling and silking, plant height and grain yield of 16 Egyptian yellow maize inbred lines. In addition, to determine accumulated growing degree units (GDU) from planting to 50% silking. Results revealed highly significant differences among tested inbreds for all studied traits at the three planting dates indicating presence of genetic diversity among tested inbreds. Also, the same trend was found for differences among locations and inbreds x location indicating climatic variability among the three testing locations and that inbreds behaved differently at different locations due to differences in climatic conditions among locations and also genetic diversity among inbreds. Number of days to 50% tasselling and silking was reduced from April to June planting as a result of increased temperatures during plant development. Longest plant heights were obtained in April planting as a result of prolonged vegetative growth due to cool - moderate temperatures prevailing at early vegetative growth. Grain yield of all tested inbreds was reduced, with few exceptions, in June 20th planting as a result of high temperatures prevailing at time of tasselling and silking which resulted in pollen, stigma or fertilization abortion and caused poor seed setting. Highest yield of studied inbreds was obtained at Gemmeize location in April 20th planting and it is recommended as a suitable production location for inbreds. Inbred Sakha 3 was the best performing under variable planting dates. Also, inbreds Sakha 1, Sakha 11, Gz 639 and Gm 1021 performed well on certain planting dates. Determination of accumulated growing degree units for tested inbreds revealed big variation among them as a result of genetic diversity of inbreds and matched well with variation present in their silking dates and specified earliness or lateness of tested inbreds. Results of GDU would help in expectation of timing for many agricultural practices such beginning of detasselling process and harvest time in hybrid breeding programs.
本研究于2021年进行,旨在研究播种日期对玉米自交系的影响,并确定其累积生长度单位(GDU)。试验在三个农业研究站(Gemmeiza、Ismaelia和Sids)进行,RCBD为4个重复。它还计划为科学界的所有研究人员提供一些优化玉米生产和减轻气候变化影响的见解。采用4月20日(早)、5月20日(最佳)和6月20日(中晚)3个种植日期,研究了不同种植日期对16个埃及黄玉米自交系抽雄吐丝至50%天数、株高和产量的影响。此外,测定了从种植到50%吐丝的累积生长度单位(GDU)。结果表明,各自交系在三个播种期的所有性状差异极显著,表明自交系间存在遗传多样性。不同地点和自交系x位置的差异也有相同的趋势,这表明三个测试地点的气候差异,自交系在不同地点的表现不同,这是由于地点气候条件的差异和自交系遗传多样性的差异。由于植株发育过程中温度升高,4 ~ 6月播种时抽雄和吐丝达到50%的天数减少。在4月种植时,植株高度最长,这是由于营养生长较长时间的结果,因为在营养生长早期普遍存在中冷温度。6月20日播种时,由于抽雄吐丝期的高温,导致花粉、柱头或受精流产,结实率低,除少数外,所有自交系的籽粒产量均有所下降。本研究的自交系在4月20日种植时产量最高,推荐作为自交系的适宜生产地点。自交系萨哈3号在变播期条件下表现最好。此外,自交系萨哈1号、萨哈11号、Gz 639和Gm 1021在某些种植日期表现良好。自交系累积生长度单位的测定结果表明,自交系间存在较大的遗传多样性差异,且与自交系吐丝日期的差异和自交系早、晚的差异吻合较好。GDU的结果将有助于许多农业实践的预期时间,如杂交育种计划中脱销过程的开始和收获时间。

Aim: The purpose of the present study was to evaluate four different types of OXIS contact areas (open [O], point [X], straight [I], and curved [S]) in primary teeth using cone beam computed tomography (CBCT) among 3- to 9-year-old children. Methods: A retrospective cohort study was performed using cone-beam computed tomography images of children, available from January 1, 2022, to July 31, 2023 in Mathura district showing the presence of caries-free contact area between primary right maxillary and mandibular 1st and 2nd molar. In this study, 65 selected contacts using OXIS criteria from the occluso-cervical and axial view at coronal level using CBCT. Result: Based on the shapes observed, the results showed four distinct types of contact regions between the primary molars, namely, O type, X type, I type, and S type; hence, the suggested categorization is known as OXIS. I type was the most prevalent pattern in the maxilla (47.06%), while O type was the most prevalent pattern in the mandible (50%). Conclusion: There are four types of intact interproximal contact areas between primary molars, which can be evaluated in three dimensions. These types are O, X, I and S. In maxilla, pattern was I > O > X > S whereas in mandible pattern was O > X > I = S.

Aims: The purpose of this study was to evaluate whether there are any significant toxic effects of the widely exposed metals on different organs (gill, liver, kidney, and muscle) of some commercially important marine fish species (Herpodon nehereus, Pampus chinensis and Hilsa ilisha). Study Design: The collection of the samples was done from January to March 2018 from Bay of Bengal near Chattogram city of Bangladesh. The study is based on randomly collected samples from the intended sampling sites (Randomized Block Design) to ensure the evenness and unbiases of the collected samples. Methodology: Analyses were performed for metals such as arsenic (As), lead (Pb) and chromium (Cr) using Atomic Absorption Spectrophotometer (AAS). During each month, five individuals each with three replications from the three targeted species were collected, with a total of 135 (45*3) fishes in the study period. Results: The concentrations of the metals found in the fishes varied in the following ranges: As: 0.029-0.071 ppm, Pb: 0.008-0.083 ppm and Cr: 0.0001-0.03 ppm. The obtained result revealed the highest concentrations of all three metals were recorded in H.nehereus fish. The organ wise lead concentration was recorded highest in kidneys and gills of examined fishes with significant variation in muscles and liver. The scenario depicted quite differently in case of chromium where concentration in gills was found to be the highest with insignificant variation in accumulation in other three organs. In case of Arsenic, kidneys and livers were the most exposed two organs in comparison to significant exposure to muscles and gills. The obtained values of arsenic accumulation were considered critical for human consumption as it was higher than the recommended values stated by WHO and FAO; but the concentration of lead and chromium were found to be safe for human consumption. The values recorded for lead were increasingly approached to the safety values. Conclusion: So, crucial steps should be taken regarding safety and environmentally friendly discharge of arsenic and lead; high levels of pollution will not only affect aquatic life but will also invite socio-economic disasters.
目的:本研究的目的是评估广泛暴露的金属对一些重要商业海洋鱼类(Herpodon nehereus、Pampus chinensis和Hilsa ilisha)的不同器官(鳃、肝、肾和肌肉)是否有显著的毒性作用。研究设计:2018年1月至3月在孟加拉国Chattogram市附近的孟加拉湾收集样本。本研究基于从预定的采样点随机收集的样本(随机区组设计),以确保所收集样本的均匀性和无偏倚。方法:采用原子吸收分光光度计(AAS)对砷(as)、铅(Pb)、铬(Cr)等金属进行分析。每个月采集3个目标鱼种的5条鱼,每条鱼3个重复,研究期间共采集了135条(45*3)鱼。结果:鱼类体内金属的浓度变化范围为:As: 0.029-0.071 ppm, Pb: 0.008-0.083 ppm, Cr: 0.0001-0.03 ppm。所得的结果显示,这三种金属的最高浓度记录在H.nehereus鱼。被检查鱼类的肾脏和鳃的器官铅浓度最高,肌肉和肝脏的铅浓度有显著变化。在铬的情况下,所描述的情况完全不同,在鳃中的浓度被发现是最高的,而在其他三个器官中的积累变化微不足道。就砷而言,肾脏和肝脏是暴露最多的两个器官,而肌肉和鳃则暴露最多。所获得的砷积累值被认为对人类消费至关重要,因为它高于世卫组织和粮农组织提出的建议值;但铅和铬的浓度被发现对人类消费是安全的。铅的记录值越来越接近安全值。结论:应采取关键措施,实现砷、铅的安全环保排放;高水平的污染不仅会影响水生生物,还会引发社会经济灾难。

A total of twelve pregnant Wistar rats were used, and randomly divided into three groups (n=4). Group A (negative control), not exposed to noise stress), group B (1mL/kg of distilled water + 4h /15 days noise stress), group C (0.04 mg/kg) of selenium-yeast + 4 h/15 days noise stress). On day 18 and 19 of gestation cognitive tests were conducted using Y-maze and Novel Object Recognition Test. A significant increase (P ˂ 0.05) was observed in the percentage alternation and discrimination index in group A compared with group B. However, the percentage alternation and DI were significantly (P ˂ 0.05) decreased in group C compared with group B. In conclusion, noise stress induces cognitive deficit, this deficit can be mitigated with the administration of selenium-yeast.
选用妊娠Wistar大鼠12只,随机分为3组(n=4)。A组(阴性对照),未受噪声胁迫),B组(1mL/kg蒸馏水+ 4h /15天噪声胁迫),C组(0.04 mg/kg酵母硒+ 4h /15天噪声胁迫)。妊娠第18天和第19天采用y形迷宫和新物体识别测验进行认知测试。与b组相比,A组的交替百分比和识别指数显著升高(P小于0.05),而C组的交替百分比和DI显著降低(P小于0.05)。由此可见,噪声应激可引起认知缺陷,酵母硒可减轻这种缺陷。

Aim: Vegetables form a major component of the human diet; however, some agricultural practices may put consumers at risk of parasitic infections. There is high consumption of   bitter leaf (Onugbu) in the rural part of Nigeria. They are eaten raw as medicinal herbs by some people. The culture of inadequate or poor washing of vegetables could pose significant and major health threats to the consumers. The aim of the study was to identify some of the parasites that may be attached to the locally consumed edible vegetable Vernonia amygdalina called Onugbu amongst Igbo speaking dialect in south eastern Nigeria. Study Design: This study is a survey that evaluated the parasitic contamination of bitter leaf grown in selected farms in Nimo in Njikoka Local Government Area of Anambra State, Nigeria.  Duration: The study lasted for six months.  Methodology: V. amygdalina leaf samples were bought directly from the farmers at 300 Naira per rap. The examination of sample was carried out using sedimentation method. Samples weighing 50g were gently washed in normal saline water.  The water used in washing was filtered and centrifuged at 300g to concentrate the parasitic stages and also to avoid damages. The sediments obtained were transferred unto labelled clean slides and examined under the light microscope at x 40 objective lens. Results: Parasites were detected in all samples collected from the farm. The commonest parasite was Entamoeba histolytica (cyst 45.5%); other parasites seen are Entamoeba coli (cyst 13.6%), B. coli (trophozoite 27.3%), Ascaris lumbricoides (ova 9.1%) and Strongyloides stercolaris (larva 4. 6%). Conclusion and Recommendations: The results provide evidence of contamination of bitter leaves from farms in Nimo in Njikoka Local Government Area of Anambra State, Nigeria with parasites of public health importance.  To avoid infection, humans should wash the leaves of this vegetable with running water or salt and water before it is eating raw.
目的:蔬菜是人类饮食的主要组成部分;然而,一些农业做法可能使消费者面临寄生虫感染的风险。在尼日利亚的农村地区,苦叶(Onugbu)的消费量很高。有些人把它们当作药材生吃。蔬菜清洗不充分或不良的文化可能对消费者的健康构成重大威胁。这项研究的目的是识别一些寄生虫,这些寄生虫可能附着在尼日利亚东南部伊博语方言中当地食用的可食用蔬菜Vernonia amygdalina上,这种蔬菜被称为Onugbu。研究设计:本研究是一项调查,旨在评估尼日利亚阿南布拉州Njikoka地方政府区Nimo选定农场种植的苦叶的寄生虫污染情况。持续时间:研究持续6个月。方法:以每袋300奈拉的价格直接从农民手中购买苦杏仁叶样品。采用沉降法对样品进行检验。用生理盐水轻轻洗涤重量为50g的样品。洗涤用的水经过过滤,离心300g,以浓缩寄生阶段,也避免损坏。将获得的沉积物转移到标记干净的载玻片上,在x40物镜下光镜下检查。结果:所有标本均检出寄生虫。最常见的寄生虫为溶组织内阿米巴原虫(囊肿占45.5%);其他寄生虫有大肠内阿米巴(囊肿13.6%)、大肠杆菌(滋养体27.3%)、类蚓蛔虫(虫卵9.1%)和粪圆线虫(幼虫4%)。6%)。结论和建议:结果提供了证据,证明尼日利亚阿南布拉州Njikoka地方政府区Nimo农场的苦叶受到具有公共卫生重要性的寄生虫污染。为了避免感染,人类在生吃之前应该用自来水或盐水清洗这种蔬菜的叶子。

Aims: To evaluate the antioxidant activities of vitamin C and bicarbonate buffers on hormones secretion and serum metabolites of heat-stressed rabbit buck. Methodology: A total of twenty-five (25) Adult rabbit bucks (New Zealand White crosses) of 12 months old were used in this study. The rabbits were randomly allotted into the experimental treatments of five treatment groups with five (5) rabbits per treatment in a Completely Randomized Design (CRD). The treatment groups consisted of Control, Sodium Bicarbonate (Na2HCO3) and Potassium bicarbonate (KNO3), Vitamin C, and baobab fruit pulp meal (BFPM) as supplements respectively. The experiment lasted for 9 weeks. Temperature humidity of the pen house and thermoregulatory condition of the rabbits were evaluated. Blood samples (5 ml) were collected from the ear vein at 10.00 h from four rabbits chosen randomly from each group of rabbits respectively before and the end of the experiment for serum metabolite, thyroxine and testosterone hormones evaluation. Results: It was found that Vitamin C and BFPM significantly (P<0.05) reduced thermoregulatory parameters and increased hormonal secretions. The pattern of secretion of serum metabolites was not significantly (P<0.05) consistent. Conclusion: It was concluded that Vitamin antioxidants were more effective to ameliorate heat stress than bicarbonate buffers.

Aims: The objectives of the research work were to evaluate the effects of mulching on soil water content, maize performance and weed growth in dry land area of Bangladesh Study Design: The experiment was laid out in a randomized complete block design (RCBD) with three replications Place and Duration of Study: Central research field of Sher-e-Bangla Agricultural University, Dhaka-1207 during November 2019 to April 2020. Methodology: The experimental field is divided into 3 blocks to represent 3 replications. There are 6 unit plots (each unit plot consists of 3m ´ 2m area) in the experimental farm. Distances of 1 m and 0.5 m are maintained between replication to replication and plots to plots, respectively. Plant to plant and row to row distances are considered to be 0.25 m and 0.75 m, respectively. The treatments are assigned in random plots. The land is ploughed four times followed by laddering to have fine tilth of the soil. The maize cultivars Shuvra and KS-510 are used as plant materials. Fig. 1 represents the six mulch treatments are imposed on the plants: Control (without mulch, CK), water hyacinth dry (10 t/ha, WH), rice straw dry (10 t/ha, RS), black polythene (4m ´ 3m, BP), white polythene (4m ´ 3m, WP), and transparent polythene (4m ´ 3m, TP) (S2). The mulches are applied as per treatment in each plot just after sowing to maintaining an equal thickness throughout the plot. Dried and cleaned mulches are used before applying to the experiment. The significance of the difference among the treatment means were estimated by the MSTAT-C package programme at 5% level of probability. Results: It is found in the experimental results that the soil water content of the no-mulching treatment is lower as compared to that of the other treatments from 0-10 cm, 10-20 cm and 20-30 cm soil depths. It is also observed that the RS mulching provides the highest soil water content, leaf area index (LAI), chlorophyll contents, and total biomass. Significant enhancement of maize yield (20.55 ton/ha) is recorded for the rice straw mulching. In contrast, the weed dry weight of 7.45g/m2 is observed in the RS mulching, which is lower than the other treatments. Conclusions: Therefore, it can be concluded that the RS mulching, compared to other mulching, would be more efficient for maximum utilization of limited water resources, weed suppression as well as to increase the maize yield. The present research approach would be applicable to manage the soil water for enhancing the maize production in dry land area.
研究目的:评估覆盖对孟加拉国旱地土壤含水量、玉米生产性能和杂草生长的影响。研究设计:试验采用随机完全区设计(RCBD), 3个重复。研究地点和时间:2019年11月至2020年4月,孟加拉国Sher-e-Bangla农业大学中心研究区达卡1207。方法:将实验场分为3块,代表3个重复。试验农场共有6个小区,每个小区面积为3m × 2m。复制与复制之间的距离为1 m,地块与地块之间的距离为0.5 m。植株与植株之间和行与行之间的距离分别为0.25 m和0.75 m。这些处理是随机分配的。这片土地翻了四遍,然后用梯子把土壤磨成细土。选用玉米品种Shuvra和KS-510作为植物材料。图1显示了对植株施加的六种覆盖处理:对照(无覆盖,CK)、水信子干(10吨/公顷,WH)、稻秆干(10吨/公顷,RS)、黑色聚乙烯(4m´3m, BP)、白色聚乙烯(4m´3m, WP)和透明聚乙烯(4m´3m, TP) (S2)。在每个地块播种后按处理方式施用地膜,以保持整个地块的厚度相等。在试验前使用干燥和清洁的地膜。通过MSTAT-C包程序在5%的概率水平上估计处理方法之间差异的显著性。结果:在0 ~ 10 cm、10 ~ 20 cm和20 ~ 30 cm土壤深度,不覆盖处理的土壤含水量低于其他处理。土壤含水量、叶面积指数(LAI)、叶绿素含量和总生物量均以RS覆盖最高。水稻秸秆覆盖显著提高玉米产量(20.55吨/公顷)。相比之下,RS覆盖的杂草干重为7.45g/m2,低于其他处理。结论:与其他覆膜方式相比,RS覆膜在最大限度地利用有限的水资源、抑制杂草和提高玉米产量方面更有效。该方法可用于旱地玉米土壤水分管理,提高玉米产量。

Aims: Present study aims to highlight an accidental death of a male Dwarf Sperm Whale scientifically known as Kogia sima which found to be as Least Concern (LC) as per IUCN Red List data. Kogia sima represents important higher trophics of marine ecosystem which faced the several threats and conservation need in Gulf of Mannar, India.  Study Design: The study undertaken during extensive coral reef monitoring survey was carried out in Gulf of Mannar under the CRAM Project of National Centre for Coastal Research (NCCR). The present report emphasize the Morphometric observation of the dead Kogia sima and try to find out possible cause of death by examining in situ investigation. Place and Duration of Study: The field study was taken in Vedalai Sea shore (N09°15.626’, E79°04.977’) under the Mandapam Union of Ramnathapuram District of Tamil Nadu. The male whale specimen was found on 5th May, 2019 lying dead on the sandy seashore. Methodology: Animal was photographed and morphological attributes were measured to identify the specimen. Several injuries have been highlighted in the paper which helps in investigating the cause of death. Results: The Dwarf Sperm Whale was infant and has mild damage on the mouth parts including scuff off skin from the body and severe blood clotting at major part of the right side near to pectoral fin. Death of this infant is not clear but it is assumed that the male infant has lost from his parents and came to the inshore area of Mandapam where it gets stuck with running boat or boulder rocks as this immature whale limits its diving capabilities. The necessary morphological characters and measures have been listed in Table 1. Conclusion: This unfortunate death clearly indicated that acute information on ecological behavior of Dwarf Sperm Whale is still under data collection stage in India and that previous conservation efforts in country must be reviewed in terms of role of local authorities, live stranded cetaceans and hunting or incidental killing which in future can build a road map for effective action plans to save this marine mammal.
目的:目前的研究旨在强调一头雄性矮抹香鲸的意外死亡,科学上称为Kogia sima,根据IUCN红色名录数据,它被发现是最不受关注的(LC)。在印度马纳尔湾,海螺是重要的高营养性海洋生态系统,面临着多种威胁和保护需求。研究设计:在国家海岸研究中心(NCCR)的CRAM项目下,在马纳尔湾进行了广泛的珊瑚礁监测调查。本报告强调对死亡的古马进行形态学观察,并试图通过现场检查找出可能的死亡原因。研究地点和时间:实地研究在泰米尔纳德邦Ramnathapuram区的Mandapam Union下的Vedalai Sea shore (N09°15.626 ',E79°04.977 ')进行。2019年5月5日,这只雄性鲸鱼被发现死在沙滩上。方法:对动物进行拍照和形态特征测定,鉴定标本。论文中强调了几处伤害,这有助于调查死因。结果:矮抹香鲸是婴儿和轻微损坏的嘴部件包括损害了人体的皮肤并严重凝血主要右侧接近胸鳍的一部分。死亡的婴儿还不清楚但它假定男性婴儿失去了他的父母,来到Mandapam那里卡住的近海区域运行船或砾岩石不成熟的鲸鱼限制其潜水能力。必要的形态特征和措施已列于表1。结论:这一不幸的死亡清楚地表明,关于侏儒抹香鲸生态行为的急性信息在印度仍处于数据收集阶段,必须从地方当局的作用、活的搁浅鲸类和狩猎或偶然杀戮等方面审查该国以前的保护工作,以便将来为有效的行动计划制定路线图,以拯救这种海洋哺乳动物。

Polymorphisms in genes that are responsible for encoding cytokines and receptors involved in the immune response, such as Toll-like Receptor (TLR) 2 in leprosy, are of great interest for immunogenetic studies. This work aimed to analyze the possible association of single nucleotide polymorphism (SNP), synonymous, rs3804100 of the TLR2 gene with leprosy. The study was conducted in Bacteriology and Mycology section of Evandro Chagas Institute, Brazil between August 2020 and July 2021.The scope of the study consisted of 122 subjects from cities of Goianésia, Rondon, Curionópolis, Altamira, Parauapebas and Redenção of the State of Pará, Brazil. Genotyping was performed by conventional PCR and sequencing in the ABI 3130 Genetic Analyzer (Applied Biosystems®) using primer nucleotides designed by the Primer3Plus program from the genomic region “Homo sapiens toll like receptor 2 (TLR2) transcript variant X6, mRNA”, deposited in GenBank with reference XM_011532216.2. The analyzes were performed based on Fisher's exact test. It was managed in accordance with Helsinki Declaration and the Brazilian National Health Council and with approval of the ethics committee at Evandro Chagas Institute, under opinion number: 3.950.570. No associations between gender and leprosy were possible (P> 0.05). However, associations were observed between age groups, which were significant between those over 46 years old (P=0.004) and the 2nd dose of BCG as a more protective agent between the groups analyzed (P=0.004). For the subjects with the typed genotypes, 68 contacts had T/T genotype and only 4 T/C genotypes, while in multibacillary (MB) group only 1 T/C genotype was found and none in paucibacillary (PB) (P> 0.05). We conclude that there is no association between the TLR2 SNP rs3804100 and leprosy in the Pará population, which still indicates the need for new immunogenetic studies with other genes involved in the immune response and a greater number of polymorphisms.
负责编码参与免疫反应的细胞因子和受体的基因多态性,如麻风病中的toll样受体(TLR) 2,对免疫遗传学研究具有很大的兴趣。这项工作旨在分析TLR2基因的单核苷酸多态性(SNP),同义,rs3804100与麻风病的可能关联。该研究于2020年8月至2021年7月在巴西Evandro Chagas研究所细菌学和真菌学部门进行。研究范围包括122名来自巴西帕尔帕州goiansamsia、Rondon、Curionópolis、Altamira、Parauapebas和reden o等城市的研究对象。在ABI 3130遗传分析仪(Applied Biosystems®)中,使用由Primer3Plus程序设计的引物核苷酸进行基因分型和测序,引物核苷酸来自基因组区域“Homo sapiens toll like receptor 2 (TLR2) transcript variant X6, mRNA”,保存在GenBank中,参考号为XM_011532216.2。分析是根据费雪的精确检验进行的。按照《赫尔辛基宣言》和巴西国家卫生委员会的规定进行管理,并得到了埃文德罗·查加斯研究所伦理委员会的批准,意见号:3.950.570。性别与麻风无相关性(P> 0.05)。然而,不同年龄组之间存在相关性,46岁以上年龄组之间存在显著相关性(P=0.004),第二剂卡介苗在各组之间具有更强的保护作用(P=0.004)。分型接触者T/T基因型68例,T/C基因型4例,多菌(MB)组T/C基因型1例,少菌(PB)组T/C基因型1例(P> 0.05)。我们的结论是,在par人群中,TLR2 SNP rs3804100与麻风病之间没有关联,这仍然表明需要对参与免疫反应的其他基因和更多的多态性进行新的免疫遗传学研究。

Aim: This study sought to investigate its effect on hepatic and renal biomarkers of female pregnant rats. Place and Duration: This work was carried out in the Department of Medical Biochemistry and Department of Science Laboratory Technology, Ekiti State University, Ado Ekiti between January and June 2021. Methodology: Locust bean seeds were purchased from an open market in Ado Ekiti, Nigeria and were processed using standard method. Fifteen female pregnant rats were divided into three groups of five each. Animals in group A were exposed to standard animal feed only. This served as the control group. Those in group B were exposed to animal feed mixed with locust beans + 0.3 mg/kg body weight of dexamethasone, while those in group C were exposed to animal feed mixed with locust beans only. At the end of the eight days treatment, animals were sacrificed and blood sample, liver and kidney were collected. Results: Exposure of pregnant rats to dexamethasone was observed to significantly (p<0.05) increased the activities of plasma aspartate amino transaminase (AST) and alanine amino transferase (ALT) as well as the concentrations of plasma total protein, bilirubin, creatinine and urea when compared with those in animals in the control as well as those treated with P. biglobosa only. The results further showed that administration of P. biglobosa only had no significant effect on plasma hepatic and renal biomarkers except urea which was significantly lower than those in the control group as well as those treated with dexamethasone. The results obtained from liver and kidney homogenate respectively are similar to those observed in the plasma. Conclusion: Exposure of animals to dexamethasone adversely unhinged hepatic and renal biomarkers investigated in the study. The study also revealed that P. biglobosa seed is beneficial to the health of the liver and kidney of pregnant female rats.
目的:探讨其对雌性妊娠大鼠肝脏和肾脏生物标志物的影响。地点和时间:这项工作于2021年1月至6月在Ado Ekiti Ekiti州立大学医学生物化学系和科学实验室技术系进行。方法:刺槐豆种子购自尼日利亚Ado Ekiti的一个公开市场,并采用标准方法进行加工。15只怀孕的雌性大鼠被分成三组,每组5只。A组仅饲喂标准饲料。这是对照组。B组饲喂混合刺槐豆的饲料+ 0.3 mg/kg体重地塞米松,C组饲喂只混合刺槐豆的饲料。8天治疗结束后,处死动物,取血、肝、肾。结果:妊娠期大鼠暴露于地塞米松后,血浆天冬氨酸转氨酶(AST)和丙氨酸转氨酶(ALT)活性以及血浆总蛋白、胆红素、肌酐和尿素浓度均明显高于对照组和单独暴露于地塞米松的妊娠期大鼠(p<0.05)。结果进一步表明,除尿素显著低于对照组和地塞米松组外,大鼠血浆肝脏和肾脏生物标志物均无显著影响。从肝脏和肾脏匀浆中分别得到的结果与在血浆中观察到的结果相似。结论:动物暴露于地塞米松对肝脏和肾脏生物标志物有不良影响。本研究还发现,大黄籽对怀孕雌性大鼠的肝肾健康有益。

Fifteen female pregnant rats were divided into three groups of five each. Animals in group A were exposed to standard animal feed only. This served as the control group. Those in group B were exposed to animal feed mixed with locust beans + 0.3 mg/kg body weight of dexamethasone, while those in group C were exposed to animal feed mixed with locust beans only. At the end of the eight days treatment, animals were sacrificed and blood sample, liver and kidney were collected. \u0000Results: Exposure of pregnant rats to dexamethasone was observed to significantly (p<0.05) increased the activities of plasma aspartate amino transaminase (AST) and alanine amino transferase (ALT) as well as the concentrations of plasma total protein, bilirubin, creatinine and urea when compared with those in animals in the control as well as those treated with P. biglobosa only. The results further showed that administration of P. biglobosa only had no significant effect on plasma hepatic and renal biomarkers except urea which was significantly lower than those in the control group as well as those treated with dexamethasone. The results obtained from liver and kidney homogenate respectively are similar to those observed in the plasma. \u0000Conclusion: Exposure of animals to dexamethasone adversely unhinged hepatic and renal biomarkers investigated in the study. The study also revealed that P. biglobosa seed is beneficial to the health of the liver and kidney of pregnant female rats.","PeriodicalId":8230,"journal":{"name":"Annual research & review in biology","volume":"105 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74340858","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}
