The present study was carried out to investigate the effectiveness of Catharanthus roseus extracts in modulating the hyperglycemia and oxidative stress (OS) of alloxan-induced diabetic rats. Treatment of rats with alloxan caused a significant (p≤0.05) increased in serum glucose concentration by the ratio of 273.61% compared to normal control group. Supplementation of the rat diets with 300, 400 and 500 mg/kg of ethanolic Catharanthus roseus stems extract (CRSE) and ethanolic Catharanthus roseus leaves extract (CRLE) decreased this value which recorded 184.72, 113.47 and 76.39%, and 139.86, 112.91 and 57.36%, respectively. The rate of attenuation exhibited a dose dependent increase with both extracts consumption. Also, CRLE is more effective in the attenuation process than CRSE. The same behavior was recorded for the biomarkers of OS levels in serum i.e. malonaldehyde (MDA). In contrary, significant (P≤0.05) improving in different antioxidant defense systems in both serum (glutathione fractions, GSH), and RBC's (antioxidant enzymes including glutathione peroxidase, GSH-Px, glutathione reductase, GSH-Rd and catalases, CAT) were recorded. Such biochemical changes observed in the present study were confirmed by the histopathological examination results. In conclusion, Catharanthus roseus possess a variety of beneficial activities and have the potential to impart therapeutic effect holistically in complicated disorders like diabetes and its complications.
本研究旨在探讨花楸提取物对四氧嘧啶诱导的糖尿病大鼠高血糖和氧化应激的调节作用。四氧嘧啶组大鼠血清葡萄糖浓度较正常对照组显著升高(p≤0.05),升高幅度为273.61%。在饲粮中添加300、400和500 mg/kg的乙醇花楸茎提取物(CRSE)和乙醇花楸叶提取物(CRLE)使该值降低,分别为184.72、113.47和76.39%,139.86、112.91和57.36%。随着两种提取物的消耗,衰减率呈剂量依赖性增加。在衰减过程中,CRLE比CRSE更有效。血清中OS水平的生物标志物(即丙二醛(MDA))也记录了相同的行为。相反,血清(谷胱甘肽组分,GSH)和红细胞(抗氧化酶,谷胱甘肽过氧化物酶,谷胱甘肽- px,谷胱甘肽还原酶,谷胱甘肽- rd和过氧化氢酶,CAT)的不同抗氧化防御系统均有显著(P≤0.05)改善。本研究观察到的这些生化变化为组织病理学检查结果所证实。综上所述,长春花具有多种有益活性,对糖尿病及其并发症等复杂疾病具有整体治疗作用。

Microbiological quality, targeting contamination with Escherichia coli, of ready-to-eat spicy meat product, “Suya” retailed in Ogbete Main Market (Location 1) and Oye Emene Market (Location 2), in Enugu, Nigeria was evaluated. Forty-eight samples of the “suya,” in forms of beef, liver, intestine, and chicken, were homogenized and serially diluted with sterile distilled water and plated into Eosin Methylene Blue agar using Pour Plate Technique. Identification of isolates were based on cultural characteristics, Gram stain reaction and Biochemical (IMViC) test, and confirmed by molecular test using 16S rRNA gene. Result showed that E coli were isolated from all the samples. Total colony counts (TCC) of all E.coli isolates were at inoculums much greater than the known infective dose for the Enteropathogenic strains. Least TCC in the April-August 2015 test samples from Locations 1/2 were: 5.6 x10/6.0 x 10, respectively; and 4.4 ×10/3.2 x 10, respectively in Locations1/2 in the SeptemberNovember 2016 test. The four highest TCC were from the cow intestine suya. In conclusion, “suya” sold to the public are contaminated, probably of faecal origin; therefore not fit for human consumption. This study also underscores the need for improved surveillance system on suya products, to enforce good food hygiene practices.
对尼日利亚埃努古Ogbete主要市场(地点1)和Oye Emene市场(地点2)零售的“Suya”即食辛辣肉制品的微生物质量进行了评估,以大肠杆菌污染为目标。48份牛肉、肝脏、肠道和鸡肉的“suya”样品均质,用无菌蒸馏水连续稀释,并使用倒盘技术镀入伊红亚甲基蓝琼脂中。根据培养特性、革兰氏染色反应和生化(IMViC)试验对分离菌株进行鉴定,并采用16S rRNA基因进行分子鉴定。结果表明,所有样品均分离到大肠杆菌。在接种时,所有大肠杆菌分离株的总菌落计数(TCC)远高于已知的肠致病性菌株的感染剂量。地点1/2 2015年4 - 8月检测样品TCC最小值分别为:5.6 × 10/6.0 × 10;和4.4 ×10/3.2 x 10,分别在2016年9月和11月的Locations1/2测试中。TCC最高的4种为牛肠素。综上所述,出售给公众的“苏亚”都是被污染的,可能是粪便来源;因此不适合人类食用。该研究还强调需要改进suya产品的监测系统,以加强良好的食品卫生规范。

The seeds of pistachio Citrullus mucosopermus Fursa much used in the diet in Côte d’Ivoire, were studied to determine their chemical composition and their nutritional potential. The biochemical parameters of the seeds of Citrullus mucosopermus Fursa characterized are dry matter, ash content, moisture content, carbohydrates, fiber, protein, amino and fatty acids. The proximate analysis of the seeds showed dry matter contents 93.6 ± 2.82 %, moisture 6.40 ± 0.14 %, ash 5.18 ± 0.06 %, carbohydrates 24.94 ± 0.18 % , fibre 9.93 ± % and crude protein 28.46 ± 0.04 %. These proteins have two of the essential amino acids with a high level of lysine whereas serine was the limiting essential amino acid. The extraction yield of the lipids (crude fat) of the seeds was 31.49 ± 0.62 %. Unsaturated fatty acids: oleic acid (1.041 ± 0.002 %), linoleic acid (0.998 ± 0.001 %) and arachidonic acid (0.881 ± 0.001) were measured. Results revealed the seeds of pistachio Citrullus mucosopermus to have great nutritional potentials with regard to their chemical composition therefore, their consumption could contribute to fulfill some food deficiencies in Côte d’Ivoire.

The high nutritional value of Hibiscus sabdariffa L calyxes is now known almost worldwide. The multiple benefits of Hibiscus juice on human health explain the new consumer demands on the preservation techniques of the nutritional qualities of Hibiscus juice. The instability of anthocyanins, the molecules responsible for the red colouring of Hibiscus sabdariffa calyxes, remains a problem despite the numerous stabilisation techniques on the subject. Platinum electrode oxygen reduction is a new athermal technique using a two-compartment electrolysis cell separated by a cationic membrane. The fruit juice is stabilised by the passage of the reduction current for a specified time. Cyclic voltammetry was used to characterise the electroactive element, the reduction peak, which is dissolved oxygen. The electroreduced Hibiscus juice was then stored at 37°C for 30 days with an untreated control. After one month of storage, determination of the anthocyanin concentration of the electroreduced extracts and the control made it possible to retain the 30mn/-6mA couple presenting a significant difference compared to the control for the stabilisation of the juices. Bubbling with nitrogen gas not only justified the negative impact of dissolved oxygen in the Hibiscus sabdariffa juice but also confirmed that oxygen is the electroactive element in the extract. The result obtained on bubbling also reveals that it is necessary to bubble for 2 hours to obtain an anthocyanin concentration of 279.21 mg/l after storage at 37°C for 30 days, whereas 282.66 mg/l is obtained for the same extract treated electrochemically (30mn/-6mA) and stored under the same conditions; both concentrations are significantly different from the control 263.37 mg/l. The electrochemical treatment with the time/intensity couple of 30min/-6mA for 500ml of Hibiscus sabdariffa juice on platinum/ECS electrode allowed to keep more than 10% of anthocyanins at 25°C and 37°C after 30 days of storage, significant compared to the control.
木槿花萼的高营养价值现在几乎全世界都知道了。木槿汁对人体健康的多重益处解释了消费者对木槿汁营养品质保存技术的新要求。花青素是导致芙蓉花萼呈红色的分子,尽管有许多稳定技术,但它的不稳定性仍然是一个问题。铂电极氧还原是一种新型的非热还原技术,它使用由阳离子膜隔开的双室电解池。通过还原电流使果汁稳定一段时间。循环伏安法用来表征电活性元素,还原峰,这是溶解氧。将电还原的木槿汁与未处理的对照组一起在37℃下保存30天。储存一个月后,测定电还原提取物和对照的花青素浓度,可以保留30mn/-6mA对,与对照相比,在果汁的稳定性方面存在显着差异。用氮气冒泡不仅证明了芙蓉汁中溶解氧的负面影响,而且证实了氧是提取物中的电活性元素。泡制结果也表明,在37℃条件下保存30天,泡制2小时可得到279.21 mg/l的花青素浓度,而在相同条件下电化学处理(30mn/-6mA)的花青素浓度为282.66 mg/l;两种浓度均与对照263.37 mg/l有显著差异。在铂/ECS电极上对500ml芙蓉汁进行30min/-6mA的电化学处理,在25°C和37°C的条件下,保存30天后,花青素含量保持在10%以上,与对照组相比具有显著性。

The millet flour sale is a very common activity in the markets of Daloa city. Despite its great consumption and its many uses by the Ivorian populations, this millet flour is produced in an artisanal or semi-artisanal way in an uncontrolled environment. This leads to various microbial contaminations thus impacting this flour quality. Our study aimed to assess the microbial contamination of millet flour sold in public markets in Daloa city. A production survey was carried out in order to obtain information on the personal hygiene of the saleswomen as well as the sale conditions. During this study, some physico-chemical and microbiological parameters of 45 flour samples (9 samples per market) were analyzed. The results revealed that the millet flour sale is exclusively carried out by young women (54.5%). In the majority of cases, these women are illiterate (72%) and have inadequate personal hygiene (55%) and an unacceptable sales environment (79%). The millet flour samples are highly contaminated and have a poor microbiological quality. In addition, certain pathogenic species such as coagulase positive Staphylococcus aureus, Escherichia coli and Bacillus cereus have been identified in the flour sold in the Daloa markets. Additionally, pH and humidity varied from sample to sample and from market to market. The presence of these germs would reflect a lack of good millet manufacturing practices, which would represent a danger for consumers. The millet flour sold in the markets would represent a danger for the population consuming millet flour in Daloa city.
在达洛阿市的市场上,卖小米粉是一项很常见的活动。尽管它的消费量很大,科特迪瓦人民也有很多用途,但这种小米粉是在不受控制的环境中以手工或半手工的方式生产的。这会导致各种微生物污染,从而影响面粉的质量。本研究旨在评估达洛亚市公共市场销售的小米粉的微生物污染情况。为了获得关于女售货员的个人卫生和销售条件的信息,进行了一次生产调查。本研究对45份面粉样品(每个市场9份)的理化和微生物学参数进行了分析。调查结果显示,销售小米粉的全部是年轻女性(54.5%)。在大多数情况下,这些妇女是文盲(72%),个人卫生不佳(55%),销售环境令人难以接受(79%)。小米粉样品污染严重,微生物质量差。此外,在达罗亚市场出售的面粉中,检出若干致病物种,例如凝固酶阳性金黄色葡萄球菌、大肠杆菌和蜡样芽孢杆菌。此外,pH值和湿度因样品和市场而异。这些细菌的存在将反映出小米缺乏良好的生产规范,这将对消费者构成危险。市场上出售的小米粉对达洛亚市食用小米粉的人来说是一种危险。

Beng-tigre is a variety of Vigna radiata, a legume of the Fabaceae’s family newly introduced in Burkina Faso for its resilience to the effects of climate change, its high nutritional value and its potential to reduce the prevalence of chronic diseases in the population. The objective of this study was to raise awareness of the nutritional and therapeutic qualities of Beng-tigre seeds among the Burkinabe population. A legume that matures between 55 and 70 days, Beng-tigre has a high nutritional value influenced by processing methods such as germination, fermentation and cooking time. Well consumed in Asia for its high protein (23.50g), fibre (16.80g), and carbohydrate (62.75g) content, as well as its high vitamin and mineral content, Beng-tigre is used as a supplement in the preparation of weaning foods and contributes to the fight against malnutrition in infants and young children. Rich in polyphenols, polysaccharides and peptides, Beng-tigre is a functional food that can contribute to the prevention and management of certain degenerative diseases. Several in vitro studies and studies on laboratory animals have shown the anti-cancer, anti-diabetic and anti-hypertensive effect of Beng-tigre. It also acts as a prebiotic to maintain the homeostasis and functions of the intestinal microbiota. A functional food with multiple virtues, Beng-tigre can be of great use in preventive medicine in developing countries where chronic non-communicable diseases are rampant. Further studies are needed at the local level to better understand the synergistic effects of the multiple components of Beng-tigre and to ensure therapeutic convenience for the population.
bengi -tigre是一种豆科植物Vigna radiata的变种,由于其对气候变化的适应能力、高营养价值和降低人口中慢性病患病率的潜力,布基纳法索新近引进了这种豆科植物。这项研究的目的是提高布基纳法索人民对孟加拉虎种子营养和治疗品质的认识。一种成熟55至70天的豆科植物,受到发芽、发酵和烹饪时间等加工方法的影响,具有很高的营养价值。由于其高蛋白质(23.50克)、高纤维(16.80克)、高碳水化合物(62.75克)含量以及高维生素和矿物质含量,本虎在亚洲很受欢迎,被用作断奶食品的补充剂,有助于对抗婴儿和幼儿的营养不良。虎牙富含多酚、多糖和多肽,是一种有助于预防和治疗某些退行性疾病的功能性食品。多项体外及实验动物实验均显示出虎牙的抗癌、降糖、降压作用。它也作为一种益生元来维持肠道微生物群的稳态和功能。虎牙是一种具有多种优点的功能性食品,在慢性非传染性疾病猖獗的发展中国家,它可以在预防医学中发挥很大作用。为了更好地了解bengg -tigre多种成分的协同作用,并确保为人群提供治疗便利,需要在地方层面进行进一步的研究。

Complementary food from blends of orange flesh sweet potatoes (Ipomea batata) (OFSP) starch, soybean (Glycine max) and groundnut (Arachis hypogea) flour was formulated and evaluated for physicochemical, functional and pasting properties. The blends of OFSP starch, soybean and groundnut flour were in the ratios of (OFSP:SB:GN): 90:5:5, 85:10:5, 80:15:5, 75:20:5, 70:25:5, 65:30:5, 60:35:5, 55:40:5, 50:45:5 for PSB1 – PSB9, while 100 % OFSP served as control. Standard analytical methods were used for all analysis. pH (4.60 – 5.69), sugar (0.71 - 3.63 %) and amylopectin (70.28 - 85.34 %) increased significantly (P≤0.05) while starch (69.09 - 87.53 %) and amylose (29.97 - 14.65) decreased with increase in soybean flour addition. Carotenoid content (11.08 – 44.60 mg/kg) will meet >200% of recommended Vitamin A requirement for infants. Bulk density, water absorption capacity, swelling power, solubility index and dispersibility ranged respectively from 0.71 - 0.83 g/ml, 0.59 - 1.35, 9.12 - 14.48, 5.57 - 9.45 and 76.00 – 80.00 %. The peak, trough, breakdown, final and setback viscosities varied significantly (P≤0.05) from 127.5 - 7291.0, 95.3 - 4332.0, 32.3 - 2959.0, 129.0 -6159.0 and 33.79 - 1827.0 RVU respectively. Increase in pH and sugar, decrease in starch, bulk density and reduction in viscosities of the complementary food with increase in soybean flour addition is very important in achieving a near neutral and high nutrient dense gruel yet thin enough for infant feeding.
以橙肉甘薯(Ipomea batata) (OFSP)淀粉、大豆(Glycine max)和花生(arachhis hypogea)粉为原料配制了辅食,并对其理化、功能和糊化性能进行了评价。对PSB1 - PSB9分别以(OFSP:SB:GN): 90:5:5、85:10:5、80:15:5、75:20:5、70:25:5、65:30:5、60:35:5、55:40:5、50:45:5和100% OFSP为对照。所有分析均采用标准分析方法。随着豆粉添加量的增加,pH(4.60 ~ 5.69)、糖(0.71 ~ 3.63%)和支链淀粉(70.28 ~ 85.34%)显著升高(P≤0.05),淀粉(69.09 ~ 87.53%)和直链淀粉(29.97 ~ 14.65)显著降低(P≤0.05)。类胡萝卜素含量(11.08 - 44.60 mg/kg)将满足婴儿维生素A推荐需求量的200%以上。容重、吸水量、溶解度、分散性分别为0.71 ~ 0.83 g/ml、0.59 ~ 1.35、9.12 ~ 14.48、5.57 ~ 9.45和76.00 ~ 80.00 %。峰值、低谷、击穿、最终和挫折粘度分别在127.5 ~ 7291.0、95.3 ~ 4332.0、32.3 ~ 2959.0、129.0 ~ 6159.0和33.79 ~ 1827.0 RVU范围内变化显著(P≤0.05)。随着豆粉添加量的增加,辅食的pH值和糖的增加,淀粉的减少,体积密度和粘度的降低对于获得接近中性和高营养密度的粥而又足够稀薄的婴儿喂养是非常重要的。

The present study was undertaken to assess the system of broiler production under contractual agreement of feed mill with the small scale broiler producer in different locations of Netrokona district in Bangladesh. The study also explored the causes why broiler farmers entering in this contractual system. The study evaluates the profitability of small scale broiler producers as well as the feed mills who were engaged in contract with the farmer. The present study was based on the primary data which were collected from five feed mills who are utilizing contacts and 60 contract broiler producers using stratified random sampling. Descriptive statistical techniques were used to estimate cost and returns of broiler farming. The study revealed that on an average, total cost of raising broiler per farm per year and per bird per batch were Tk. 10,90,389 and Tk. 175 respectively. The gross return from broiler production per farm per year and per bird per batch was Tk. 13,44,737 and Tk. 208 respectively. Net returns of broiler production per farm per year and per bird per batch were estimated at Tk. 2,54,348 and Tk. 33 respectively. Moreover, it is evident from the study that the benefit cost ratio of broiler farms was 1.23. So, it is clear from the study that production of broiler under contractual system was profitable and the contract farmers were getting benefit. On the other side, feed mill sales center who are engaged in contracts were also benefitted by keeping extra profit in all credited inputs of broiler production by practicing the system. Cobb-Douglas production function analysis was used to determine the major factors namely age, education, family size, feed cost, day old chick cost, labor cost, medicare and additives cost and training of the producer affecting the gross return of broiler production. But the main influencing factors for broiler production were feed cost, day old chick cost, medicine and vaccine cost, education and training of the broiler farmer. The study also identified some problems related to contractual system and, production and marketing system of broiler production. Finally on the basis of the findings, some recommendations were made for the development of poultry production in Bangladesh. It may concluded that with effective management, contract farming system of feed mill’s can be a means to develop production of broiler farming and marketing the output in a way that is profitable for the both farmer and the feed mill.
本研究是根据饲料加工厂与孟加拉国Netrokona地区不同地点的小规模肉鸡生产商的合同协议,对肉鸡生产系统进行评估。研究还探讨了肉鸡养殖户进入这种承包制的原因。该研究评估了小规模肉鸡生产者以及与农民签订合同的饲料加工厂的盈利能力。本研究采用分层随机抽样的方法,从5家使用联系人的饲料厂和60家合同肉鸡生产商收集了初步数据。采用描述性统计技术估算肉鸡养殖的成本和收益。研究表明,平均每个农场每年饲养肉鸡和每批鸡的总成本分别为10.10塔卡、90389塔卡和175塔卡。每个农场每年和每批鸡生产的总收益分别为1.13塔卡、4.47 737塔卡和208塔卡。估计每个农场每年肉鸡生产的净收益和每批次每只鸡的净收益分别为2.52、54,348和33塔卡。此外,从研究中可以看出,肉鸡养殖场的效益成本比为1.23。因此,研究表明,承包制肉鸡生产是有利可图的,承包制肉鸡养殖户获得了利益。另一方面,从事合同的饲料厂销售中心也通过实行该制度,在肉鸡生产的所有信用投入中保持了额外的利润。采用Cobb-Douglas生产函数分析确定了影响肉鸡生产总收益的主要因素,即年龄、受教育程度、家庭规模、饲料成本、日龄鸡成本、人工成本、医疗保险和添加剂成本以及生产者培训。但影响肉鸡生产的主要因素是饲料成本、日龄鸡成本、药品和疫苗成本以及肉鸡养殖户的教育和培训。研究还发现了与肉鸡生产合同制度和产销制度有关的一些问题。最后,根据调查结果,对孟加拉国家禽生产的发展提出了一些建议。由此可以得出结论,通过有效的管理,饲料厂的合同养殖制度可以成为发展肉鸡养殖生产的一种手段,并以一种对农民和饲料厂都有利的方式销售产品。
