A total of 456 day-old Isa brown pullet chicks were allotted to four dietary treatments in six replicates in a completely randomized design experiment. Aqueous extracts of bitter leaf and water leaf were used as test dietary treatments for the birds. In treatment 1, a commercial multivitamin (vitalyte) was given in water (1g/L) to the birds to serve as the control. In treatments 2 and 3 aqueous extracts of bitter leaf and waterleaf were given at 100ml/L of water, while in treatment 4 mixed bitter leaf and water leaf aqueous extract (50% each in composition) was given. On the last day of the feeding trial, blood samples were collected from the birds for vitamins and minerals analysis. The observed results showed that dietary treatments significantly affected the blood serum parameters. Vitamin A was significantly higher (P < 0.05) in the vitalyte birds. The values ranged from 0.27iu in the bitter leaf birds to 0.37iu in the vitalyte. Vitamin C was more abundant (1.84iu) in the bitter leaf treated pullets and was significantly reduced (1.21iu) in the vitalyte. Vitamin D was significantly (P < 0.05) higher (0.35 iu) in the water leaf as well as vitamin E (10.14iu) while they were highly reduced considerably in the vitalyte administered birds, 0.16 and 4.83iu respectively.

However, in doing so, it is important to ensure that such plant materials are not deleterious to the animals. This research therefore examines the effect of bush buck (Gongronema latifolia) leaf extracts as dietary supplements on haematological and serum biochemical parameters of broiler chickens. Fresh leaves (6kg) of bush buck (Gongronema latifolia) were after rinsing with de-ionized water air-dried for ten (10) days under room temperature and were ground in a hammer mill to pass through 0.5mm sieve. It was thereafter dissolved in de-ionized warm water (40oC) at 1kg per 5 litres of water and was left to settle for 1 hour before decanting the supernatant. One hundred and ninety-two (192) broiler chicks, after brooding for two weeks were divided into six (6) dietary treatment groups of thirty two (32) birds each. Birds on dietary treatment 1, had no vitamin/mineral supplement in water, while dietary treatment 2 birds had supplemental commercial vitamin/mineral premix (vitalyte extra). Dietary treatments 3, 4, 5 and 6 had Gongronema latifolia leaf warm water extract in the following ratios; 25, 50, 75, and 100ml/litre of water respectively. The vitalyte extra was administered (5g/l) once a week while the birds had access to feed and water/GLLE ad libitum. On the last day of the experiment, blood samples were collected from the birds for haematological analysis. All the assayed parameters such as packed cell volume (PCV), white blood cell (WBC), red blood cell (RBC), heterophil (H), lymphocyte (L), monocyte (M), eosinophil (E), basophil (B), haemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular haemoglobin concentration (MCHC) and mean corpuscular haemoglobin (MCH) were significantly (P<0.05) influenced by the dietary treatments. The analyzed serum biochemical indices such as total protein, albumin, globulin, creatinine, uric acid, aspartate aminotransferase, alanine aminotransferase, sodium and potassium were generally better in the 25ml/l GLLE. Glucose was significantly reduced in the vitalyte treatment while total cholesterol, high and low density lipoprotein were least in the 50ml/l GLLE treatment. In conclusion, the results above revealed that the Gongronema latifolia leaf warm (40oC) water extract of 50ml/l was safer and supported better health and wellbeing of the broiler chickens. This shows that Gongronema latifolia leaf warm (40oC) water extract could be used to wholly replace the conventional vitamins and minerals (vitalyte extra) in broiler diets without any adverse effect on growth and health performance of the birds.","PeriodicalId":219819,"journal":{"name":"Haya: The Saudi Journal of Life Sciences","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122380583","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}

Moringa oleifera is very rich in nutrition but has undesirable taste and flavor. However, addition of ginger takes the edge off the bitter spinachy taste of Moringa oleifera leaves. Lactic acid bacteria (LAB) are important microbes that have long been used in both traditional and modern industrial food fermentation. Lactic acid bacteria can be used for production of food due to their ability to coax microorganisms into producing In the process of food fermentation; microorganisms produce enzymes to break down complex compounds to simple bio-molecules for several biological activities such as proteinase, amylase, mannase, cellulase, and catalase. The aim of this research work is to determine the effect of Lactic acid bacteria (LAB) fermentation on the quality attributes of tea-like beverage produced from blends of Moringa oleifera leaves and Ginger(Zingiber officinale). The results showed that The phenotypic and biochemical characteristic of Blends of Drumstick leaves (Moringa oleifera) and Ginger (Zingiber officinale) reveals that the isolates were presumptively categorized to belong to the genus Lactobacillus, the isolates are gram positive, cocci, rod shaped, either, short rod or long rods, non-sporulating, ferments carbohydrate, non-motile and catalase negative. Technological properties of isolates are the properties that indicate the quality of the isolate to be used as a starter culture in the course of fermentation. A total of 35 colonies were isolated from the blend samples. Of them, 3 colonies were identified as Lactobacillus species, through observation of phenotypic characters, and identification, It was found that L. plantarum had tolerance under acid conditions, as its viable cell count remained at pH 2.0 and under 1.0 % bile salt condition, after 72 h incubation time.

This was done in order gauge the impact of anthropogenic inputs such as pesticides, fertilizers, oil spillage and other industrial and anthropogenic wastes disposal, especially at the coastal parts of the region on bottom sediments. Three sampling Stations were chosen for the purpose of this research. Station 1 (Buo-Ama Creek) was established close to the entrance of Buo-Ama creek, in the Nun River estuary. Station 2 (Erewei- Kongho) was established along one of the tributaries of the Nun River estuary around Erewei- Kongho. Station 3 was established in Ogbokiri. Sediment samples were collected with the aid of a soil auger and a galvanized metal core cylinder from the three (3) sampling stations along a transect running from the low intertidal level (LIL), through the mid intertidal level (MIL) to the high intertidal level (HIL). Sediment samples were analysed in the laboratory using the method of Atomic Absorption Spectrophotometer (AAS). Means and standard deviations were calculated for all the measured parameters. A one-way ANOVA was employed at the 95% confidence limit to test for differences across stations in the heavy metals. Turkey HSD post HOC test was also employed to separate means and identify where variability and similarities exist. This was aided by the SPSS 20.0 statistical tool kit. The result shows that Pb has the highest concentration, followed by Zn, Ni, Cd, and Mn respectively. The lowest values of all metals were observed at station 2, while the highest concentrations of metals were recorded at sampling stations 1. The results show that the value of Pb was highest in station 1(1.347±0.001), followed by Station 3 (1.24±0.001). Station 2 had the least mean value of Pb (0.884±0.001). Cd showed similar patterns across the three sampling stations 1, 2 and 3, with the values 0.068±0.002, 0.046±0.001, and 0.054±0.002 respectively. Ni also presented slight difference across the three sampling stations. Concentration of Zn were higher in station 1 and 2 (1.265±0.002 and 1.038±0.002), than in station 3 (0.725±0.001). All metal concentration was however lower than the international permissible limited. The concentrations of Mn were also observed to present a similar pattern across the sampling stations. There is a significant difference (P<0.05) in all heavy metal parameters across all stations. Heavy Metal Concentrations were found to decrease with increasing distance from the river mouth, suggesting that anthropogenic inputs, related to agricultural and domestic discharge into the river, are the major sources of heavy metals in the river sediments. Land based activities therefore have a profound effect on aquatic ecosystem stability and health.","PeriodicalId":219819,"journal":{"name":"Haya: The Saudi Journal of Life Sciences","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125494188","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}

Rajalakshmi, Mary Shamya","doi":"10.36348/sjls.2022.v07i07.004","DOIUrl":"https://doi.org/10.36348/sjls.2022.v07i07.004","url":null,"abstract":"Developing wound infection in type Ⅰ or Ⅱ diabetic people had risk complications like gangrene. Although there are enough antibiotic ointments or creams, still it needs physician dressing and continuous monitoring of wound. So, to make it simple and more effective, a combination of transdermal drug delivery route with herbal usage contribute in controlled release of medication with minimum undesirable side effects. And also help to treat wound infections by self-medication. This work is focused, to formulate wound healing transdermal patch for diabetics with Momordica cymbalaria tuber extract. A sequence of techniques was performed to analyse antioxidant content then Starch assay was performed In vitro to evaluate its healing efficacy, determine cytotoxicity using zebra fish embryos and artemia salina using hexane extract of tuber. Optimized combination is used to prepare Patch by solvent evaporation method then evaluated the patch by organoleptic and physico-chemical properties. The result proofs, the tuber extract had Strong Antioxidant activity whereas weak cytotoxicity showed in two concentration (25 and 50µg/ml) towards brine shrimp lethality assay and fish embryo toxicity. High migration rate found in 25µg/ml and 50µg/ml in scratch assay using Human Epidermal Keratinocytes. Evaluated the patch for its organoleptic and physico-chemical properties, it shows good result. As a final observation of the study, bio compounds present in tuber extract proved to enhance wound healing and could pave way as alternate to the synthetic wound healing patches owing to its ecofriendly, economical and herbal nature be natural replacement to hasten wound healing especially in diabetic patients.","PeriodicalId":219819,"journal":{"name":"Haya: The Saudi Journal of Life Sciences","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126762991","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}
