Due to extensive use of chemical fertilisers, pesticides and hormone injections our food is becoming poisonous and to eliminate such poisons from our body natural products can prove to be very effective. The therapeutic use of cow urine has a long history in India. And recently being considered as potent bio pesticide, the cow urine has been considered in the present study to evaluate its ameliorative potential against the oxidative stress and genotoxicity induced in the brain tissue of rat by intoxication of chlorpyrifos (CPF). Chlorpyrifos is a broad spectrum conventional organophosphate agrochemical used to control a variety of pests in agriculture and for domestic purposes. For the experiment the antioxidant potential of cow urine was measured by DPPH assay. Further in present inquisition ratswere divided into two groups, one exposed to1/8 th , 1/4 th and 1/2 of LD 50 of CPF and other group of rats were treated with cow urine consecutively for ten days prior to exposure of CPF. Brain tissue was collected after 24hrs, 48hrs and 72hrs of treatment. Symbolic elevation in %tail DNA, tail moment and MDA levels while reduction in SOD, CAT and GST activities was noted in chlorpyrifos treated groups as compared to control groups. The effect of dose was also ascertained for all parameters. On the other hand, pre-treatment with cow urine significantly abridged the effect of CPF intoxication. Thus, it appears from the study that cow urine ameliorates pesticide induced cancer insurgence in rat because of its high antioxidant levels and can be used as a viable potential substitute for anti-cancer therapy.
由于化肥、杀虫剂和激素注射的广泛使用,我们的食物正变得有毒,要从我们的身体中消除这些毒素,天然产品被证明是非常有效的。在印度,牛尿的治疗用途有着悠久的历史。近年来,牛尿被认为是一种有效的生物农药,本研究评价了牛尿对毒死蜱中毒大鼠脑组织氧化应激和遗传毒性的改善潜力。毒死蜱是一种广谱的常规有机磷农药,用于控制农业和家庭中的各种害虫。本实验采用DPPH法测定奶牛尿液的抗氧化电位。在本研究中,将大鼠分为两组,一组暴露于CPF的1/8、1/4和1/2的ld50,另一组在CPF暴露前连续十天用牛尿处理。分别于治疗24小时、48小时和72小时采集脑组织。与对照组相比,毒死蜱处理组尾DNA、尾时刻和MDA水平显著升高,SOD、CAT和GST活性显著降低。确定了剂量对各参数的影响。另一方面,用牛尿预处理可显著缩短CPF中毒的影响。因此,从研究中可以看出,由于牛尿具有较高的抗氧化水平,可以改善农药诱导的大鼠癌症的发生,可以作为抗癌治疗的可行的潜在替代品。

Before the Industrial Revolution, the concentration of CO2 in the atmosphere was 280 ppm and in time increasing fossil fuels use increased CO2 concentration up to 416 ppm in a preset time. Meanwhile, increasing population growth (around 8 billion) has also started to put serious pressure on soil ecosystem for more food production demand. With the demand for more food production, intensive chemical inputs and soil cultivation practices applied to the soil has increased the amount of CO2 released to the atmosphere. Increasing CO2 concentration in the atmosphere triggers global warming and climate change which is negatively affect plant growth and consequently food security. In order to ensure food security under climate change conditions, it seems that the need to re-enact nature's own mechanisms has arisen. In this context, it is aimed to reduce the effect of climate changes by keeping more carbon as a sink by operating the effects of plant root mechanisms on the soil health according to ecological principles. Under long term filed conditions the effects of different soil-plant managements, especially mycorrhiza fungi, were investigated. Since 1996, several researches have been carried out under long-term field studies to see the effect of mycorrhizal fungi and other microorganisms on carbon sequestration, as well as the emission of CO2 from the greenhouse gases to the atmosphere. Regularly CO2 flux, emissions, photosynthesis rate, C, N sequestration and yield parameters are measured. Data are yearly evaluated. Results revealed that under long-term field conditions, organic fertilizers application and mycorrhizal inoculation sequestered more carbon in soil profile. It has been shown that, using animal manure, compost, biochar, nitrogen-fixing bacteria and mycorrhizal fungi significantly kept more carbon in plant tissue and soil. It is determined that there is an increase of 1.5 ppm CO2 concentration in atmosphere per year. It has been determined that especially long-term addition of organic matter and management of natural mycorrhizae increase soil organic carbon and accordingly soil quality and productivity increase. As the effect of climate change and population growth have significant negative impact on food security, definitely a new agriculture revelation is needed to overcome of climate and food security problem. Soil and plant management must be managed according to low-input ecological principles.
在工业革命之前,大气中的二氧化碳浓度为280 ppm,随着化石燃料使用的增加,二氧化碳浓度在预设时间内增加到416 ppm。与此同时,不断增长的人口(约80亿)也开始对土壤生态系统造成严重压力,以满足更多的粮食生产需求。随着对更多粮食生产的需求,对土壤进行的集约化化学投入和土壤耕作增加了向大气释放的二氧化碳量。大气中二氧化碳浓度的增加引发全球变暖和气候变化,对植物生长产生负面影响,从而影响粮食安全。为了确保气候变化条件下的粮食安全,似乎有必要重新制定大自然自身的机制。在此背景下,其目的是根据生态学原理,通过操作植物根系机制对土壤健康的影响,保持更多的碳作为汇,从而减少气候变化的影响。在长期田间条件下,研究了不同土壤-植物管理方式,特别是菌根真菌的影响。自1996年以来,在长期的实地研究中开展了几项研究,以了解菌根真菌和其他微生物对固碳的影响,以及温室气体中二氧化碳的排放到大气中。定期测量CO2通量、排放量、光合速率、C、N固存和产量参数。数据每年评估一次。结果表明,在长期田间条件下,施用有机肥和接种菌根对土壤剖面碳的固碳作用更大。动物粪便、堆肥、生物炭、固氮菌和菌根真菌能显著提高植物组织和土壤中的碳含量。经确定,大气中CO2浓度每年增加1.5 ppm。特别是长期添加有机质和管理天然菌根可以增加土壤有机碳,从而提高土壤质量和生产力。由于气候变化和人口增长对粮食安全产生了显著的负面影响,克服气候和粮食安全问题需要新的农业启示。土壤和植物管理必须按照低投入的生态原则进行管理。

Bugesera is among the district located in Eastern Province of Rwanda where drought is a limiting factor for agriculture. Innovation and adoption of new technologies in agriculture is one of the keys that should reduce poverty in that area. The general objective of this study was to assess the level of the adoption of organic peppers production practices among smallholder farmers in Rwanda. A case study of Bugesera district. This study employed a cross-sectional survey design and a multi-stage sampling technique to select a sample of 150 respondents was used. The findings of logit regression analysis indicated that four factors such as education level, land size, farming experience, gender and enhanced soil fertility had positive and significant influence on adoption of organic pepper production practices. The demand for organic products creates new export opportunities. The market returns from organic agriculture can potentially contribute to local food security by increasing family incomes. The findings showed that the most common constraints to adoption of organic pepper production practices were lack of stable irrigation system, lack stable and reliable market, unreliable climate, high cost of inputs, lack of extension services, and inadequate capital respectively. Based on these findings, it was recommended that provision of training and technical advice on organic farming practices through agricultural extension services and developing information networks among farmers is vital, input subsidy, harvest(yield) insurance, financial inclusion (accessing affordable loans) is more crucial for stallholder farmers. Government should made effort in stable and durable irrigation systems, improvement of extension services through field visits and more effort in marketing of cash crops especially vegetables because are more perishable.
Bugesera是卢旺达东部省份干旱是农业限制因素的地区之一。农业领域的创新和采用新技术是减少该地区贫困的关键之一。本研究的总体目标是评估卢旺达小农采用有机辣椒生产做法的程度。以Bugesera地区为例。本研究采用横断面调查设计,采用多阶段抽样技术,选取150名调查对象。logit回归分析结果表明,教育程度、土地面积、农作经验、性别和土壤肥力等4个因素对辣椒有机生产方式的采用有显著的正向影响。对有机产品的需求创造了新的出口机会。有机农业的市场回报可以通过增加家庭收入来促进当地的粮食安全。研究结果表明,制约有机辣椒生产的主要因素分别为:缺乏稳定的灌溉系统、缺乏稳定可靠的市场、气候不稳定、投入成本高、缺乏推广服务和资金不足。基于这些发现,建议通过农业推广服务和发展农民之间的信息网络提供有机农业实践培训和技术咨询至关重要,投入补贴、收获(产量)保险、金融包容性(获得负担得起的贷款)对摊主农民更为重要。政府应努力建立稳定和持久的灌溉系统,通过实地考察改善推广服务,并更努力销售经济作物,特别是蔬菜,因为它们更容易腐烂。

Investigation about the lipid composition of some freshwater fishes. 一些淡水鱼类脂质组成的研究。
Pub Date : 2022-06-20 DOI: 10.52804/ijaas2022.3121
B. Kumar, A. Jha
In this work we were study about the lipid composition of some fresh water fishes collected from Darbhanga locality. Fish is consumed in this Gangetic plain mainly for protein and lipids. Fishes contain unsaturated fatty acids as lipid-component. Accordingly, the study was conducted by selecting two river stretches of Darbhanga District. These included stretches of river Kamala located in village Pokharam and stretches of river Balan located in village Pohaddi. Fish collections was done with bag nets of standardized dimensions with several mesh-sizes. There is selection of Labeo rohita (Rohu), Labeo calbasu and Catla catla a plankton feeder, phytoplankton and detritus feeder respectively in water column. The health clues hidden in fish flesh consumption encountered through popular dailies and reviews (The Times of India, Sunday review, July.18 Aug.8 and Aug.22 and Dec.18, 2001) attracted the present attention on this particular problem. According to fat extraction by Soxhlet extraction method; fat content of Labeo rohita varied between 23-30% while the iodine value was in range of 90-102. The level of triglyceride could be measured between 402-410 mgm (%). The saponification value was recorded between 101-171.2 and acid value between 8.81and 9.21. Whereas, the fat contents of Catla catla was recorded between 24.6-26.7%, Iodine value in the range of 96-97, saponification value between 152.4-158.7 and acid value between 7.8-8.61. These values in L. calbasu were recorded as: fat content 25.6 - 27.1%; Iodine value 96-98; Saponification value 133.4-140.3 and acid value 6.93-7.6. The findings suggest that the total fat content in all the major carps were comparable to each other. The study also suggests that in general the fat content of fish increases during winter season probably on account of availability of quality food. However, with regard to  6 and  3 profile the Labeo rohita and Labeo calbasu the phytoplankton and detritus feeders respectively shows a better range of  3 fatty acids than Catla catla , a zooplankton feeder which appears to be rich in  6 fatty acids.
本文对采自达尔邦加地区的一些淡水鱼的脂质组成进行了研究。恒河平原食用鱼主要是为了获取蛋白质和脂质。鱼类含有不饱和脂肪酸作为脂质成分。因此,研究是通过选择达尔班加地区的两个河段进行的。其中包括位于Pokharam村的Kamala河和位于Pohaddi村的Balan河。鱼的采集是用几种网目尺寸标准化的袋网进行的。水柱中分别有浮游动物、浮游植物和碎屑动物的选择,有罗虎鱼(Labeo rohita)、卡拉贝鱼(Labeo calbasu)和卡拉贝鱼(Catla Catla)。通过流行的日报和评论(《印度时报》,2001年7月18日、8月8日、8月22日和12月18日星期日评论)发现的食用鱼肉中隐藏的健康线索引起了人们对这一特殊问题的关注。根据脂肪提取采用索氏提取法;脂肪含量为23 ~ 30%,碘含量为90 ~ 102。甘油三酯的水平可以在402-410毫克(%)之间测量。皂化值在101 ~ 171.2之间,酸值在8.81 ~ 9.21之间。脂肪含量为24.6 ~ 26.7%,碘值为96 ~ 97,皂化值为152.4 ~ 158.7,酸值为7.8 ~ 8.61。这些值分别为:脂肪含量25.6 ~ 27.1%;碘值96 ~ 98;皂化值133.4 ~ 140.3,酸值6.93 ~ 7.6。研究结果表明,所有主要鲤鱼的总脂肪含量是相似的。研究还表明,一般来说,鱼类的脂肪含量在冬季增加,这可能是由于优质食物的供应。然而,在6和3剖面上,浮游植物和碎屑食性动物Labeo rohita和Labeo calbasu分别显示出较好的3脂肪酸范围,浮游动物食性动物Catla Catla似乎富含6脂肪酸。

Prevalence Occupational Hazards among Dentists of Uttarakhand: A Descriptive Study 北阿坎德邦牙医职业危害患病率:一项描述性研究
Pub Date : 2022-06-20 DOI: 10.52804/ijaas2022.3115
G. Pant, D. Vinay
Dentists are known to have occupational health issues, including dental threats of a physical, environmental, chemical and psychosocial type. The poor medical outcomes with occupational health issues include musculoskeletal disorders (MSDs), eye injuries, vibration neuropathy and neurological problems. Problems such as contact dermatitis, hearing loss and irritation from dental products were also observed. Dental workers in the dental school and functional sector have a number of challenges including a range of occupational health threats as well as hazards such as the reactions of infectious diseases, pollution and vibration, as well as allergies to dental products. This study was conducted to assess occupational hazards among the dental surgeons of Uttarakhand. Among the study group of 80 dentists, 54 were males and 26 were females. Descriptive cross-sectional survey was conducted using a self-administrated questionnaire. The study reveals that mean percentage scores were found maximum in the area of ‘psychological hazards (90 %), followed by 72.70 per cent in the area of ergonomic hazard, 45.93 per cent in accidental hazard and only 1.67 per cent in the area of ‘physical hazard’. The chances of occupational hazards are more common in dentists. Almost all the private dental practitioners were suffering from the occupational hazards. Back problems were common. Regular training and workshops can help lower such problems.
众所周知,牙医存在职业健康问题,包括身体、环境、化学和心理社会类型的牙科威胁。与职业健康问题相关的不良医疗结果包括肌肉骨骼疾病(MSDs)、眼部损伤、振动神经病和神经问题。还观察到接触性皮炎、听力损失和牙科产品刺激等问题。牙科学校和职能部门的牙科工作者面临许多挑战,包括一系列职业健康威胁和危害,如传染病的反应、污染和振动,以及对牙科产品的过敏。本研究旨在评估北阿坎德邦牙科外科医生的职业危害。在80名牙医中,54名为男性,26名为女性。描述性横断面调查采用自填问卷进行。研究表明,心理危害领域的平均百分比得分最高(90%),其次是人体工程学危害领域的72.70%,意外危害领域的45.93%,而物理危害领域的平均百分比得分仅为1.67%。职业危害的机会在牙医中更为常见。私家牙科从业人员几乎都存在职业危害。背部问题很常见。定期的培训和研讨会可以帮助减少这些问题。

Effect of Vehicular Pollution on Avenue Trees of NH-31 from Naugachhia to Begusarai. 机动车污染对NH-31 Naugachhia至Begusarai行道树的影响
Pub Date : 2022-06-20 DOI: 10.52804/ijaas2022.3122
S. Kumari
The major pollutant emitted from vehicles are Carbon monoxide, Nitrogen oxide, Hydrocarbons, Sulphur dioxide and Sulphur trioxides, tetraethyl lead and tetramethyl lead, etc. These pollutants directly affect the Avenue trees by reducing their Chlorophyll content, increasing Ascorbic acid and closing Stomata. To evaluate the effect of vehicular pollution on avenue trees of NH-31 from Naugachhia to Begusarai (Distance 113 Km) APTI of 10 plants were calculated. APTI ranged in between 7.067 to 13.755. The minimum was of Aegle marmelos and maximum of Acacia arabica followed by Ficus benghalensis, Ficus religiosa, Azadirachta indica and Saraca indica.
车辆排放的主要污染物有一氧化碳、氮氧化物、碳氢化合物、二氧化硫和三氧化硫、四乙基铅和四甲基铅等。这些污染物通过降低林荫道乔木的叶绿素含量、增加抗坏血酸和关闭气孔来直接影响林荫道乔木。为了评价机动车污染对NH-31从Naugachhia到Begusarai(距离113 Km)行道树的影响,计算了10株树木的APTI。APTI指数在7.067到13.755之间。甜瓜最低,阿拉比卡最高,其次是榕树、榕、印楝和印度树。

Various land systems show various soil properties and understanding the variation in soil properties within farmland use is essential. Thus, the study was conducted from July 2019 to September 2019 in Padampur, Chitwan of Nepal to examine the soil nutrient conditions of various land use systems by designing in Randomized Complete Block Design. Different land use systems silvipasture, forest land, fodder land, low land, upland and grass land were taken to conduct a study and each land system was replicated four times in different fields. Different land systems showed very low, low and medium total nitrogen content, high and very high available phosphorus, low and high potassium content, very low organic matter and neutral to alkaline pH. Among various land use systems, grass land had the highest total nitrogen percentage (0.11%) and fodder land recorded the highest available phosphorus (120.10 kg/ha). Further, the highest potassium content (134.59 kg/ha) was obtained in low land, forest land recorded the highest soil organic matter (0.31%) and the highest pH (7.94) was obtained in silvipasture.
