Effect of Fermented Lagenaria (Adenopus breviflorus) Fruit Extract on the Heamatological and Serum Biochemical Indices of Broiler Chickens

The experiment involved 126 day old broiler chicks (Arbor acre plus) which lasted for six weeks after two weeks of acclimatization. The project was carried out in a completely randomized block design to evaluate the haematological and serum biochemical parameters of broilers served fermented lagenaria fruit extract (FLFE) at three days interval. The birds were weighed and randomly distributed into six dietary treatment group. Birds in treatment A (control) were given vaccine and drugs only, birds in treatment B were given vaccine only, birds in treatment C were given drugs only, but birds in treatments D, E and F were served (100, 200 and 300)ml of FLFE in 250ml of water, respectively. Each treatment was replicated three times with seven birds per replicate. The birds were maintained on starter and finisher marsh for starter and finisher phase, respectively. Feeds and water were served ad libitum. Data collected were subjected to Analysis of Variance (ANOVA) and comparisons were made using Duncan’s Multiple Range Test and significance was accepted at (P<0.05). The parameters tested were packed cell volume (PCV), haemoglobin (Hb), red blood cell (RBC), white blood cell (WBC), platelet (P), mean cell volume (MCV), mean cell haemoglobin (MCH), mean cell haemoglobin concentration(MCHC), lymphocyte (LYM), heterocytes (HET), monocytes (Mn), eosinophils for haematological indices and total serum protein (TSP), albumin(Al), globumin (Gb), creatinine (Cr), alanine amino transminase (ALT), aspatate amino transminase (AST), alkaline phosphate (ALP), blood urea nitrogen (BUN) and cholesterol (CH) for serum biochemistry. The results showed significant (P<0.05) effects of the parameters studied across the treatment groups. The PCV was highest (40.00%) on the birds placed in control, and least on the birds served 100-300ml FLFE (29.50-33.00%). Similar scenario was observed for the birds in control for the Hb (13.20%) compared to those served 100-300ml FLFE (9.40-10.70%). The birds in treatments C (drugs only), D (100ml FLFE) and those in F (300ml FLFE) had the highest concentration of white blood cells which were 1.92, 2.12 and 1.87x104/ml, respectively. The birds served 100-300ml FLFE had reduced concentration of Hb of 21.25% compared to control, and they had elevated concentration of WBC of 25.82% compared to control. The birds placed on vaccines only and drugs only had elevated WBC of 26.00 and 34.50%, respectively compared to control. The FLFE of 100-200ml had elevated platelet (353.00-314.50x103/ml) with reference to control. The FLFE had no significant (P<0.05) effect on TSP, GB, AL, ALP and BUN. However, concentration of CH increased with increased concentration of FLFE as the bird offered 100ml had CH of 42.50mg/dl, compared to those on 200ml and 300ml whose value were 68.50 and 89.00mg/dl, respectively. Broiler chicken can tolerate 100-300ml FLFE for improved blood formation. Keywords: Lagenaria, Hematology, Serum biochemistry, Broiler, Vaccin

Mapping local patterns of childhood overweight and wasting in low- and middle-income countries between 2000 and 2017

A double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low- and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall across LMICs between 2000 and 2017, from 8.4 (62.3 (55.1�70.8) million) to 6.4 (58.3 (47.6�70.7) million), but is predicted to remain above the World Health Organization�s Global Nutrition Target of <5 in over half of LMICs by 2025. Prevalence of overweight increased from 5.2 (30 (22.8�38.5) million) in 2000 to 6.0 (55.5 (44.8�67.9) million) children aged under 5 years in 2017. Areas most affected by double burden of malnutrition were located in Indonesia, Thailand, southeastern China, Botswana, Cameroon and central Nigeria. Our estimates provide a new perspective to researchers, policy makers and public health agencies in their efforts to address this global childhood syndemic. © 2020, The Author(s)

Diabetogenic potential of dexamethasone and effect Annona muricata methanolic bark extract as post-exposure therapy in albino rats

Diabetes mellitus (DM) is a metabolic disorder leading to high level of morbidity and mortality in human population and it has been identified as the leading cause of death from non- nfectious diseases. The use of dexamethasone has been on the increase due to widearray of therapeutic effects it&nbsp; has and the use has mostly been without prescription, since it is a non- prescription drug. Therefore, the potential of dexamethasone to induce DM&nbsp; was studied. Some of the drugs currently used in the treatment of diabetes have their own problematic effects and also expensive, Annona muricata methanolic bark extract (AMMBE) was used in the treatment of dexamethasone-induced diabetes in rats. The research was carried out on albino rats in Federal College of Animal Health and Production Technology, Ibadan and lasted for twenty-eight (28) days. The rats were allotted into four groups (A, B, C and D). Group B, C and D were induced with glucocorticoid (Dexamethasone) (2mgkg-1) daily for seven (7) days intraperitoneally,&nbsp; while group A which was the positive control were given distilled water throughout without induction with glucocorticoid. Group B (the negative control) was induced with glucocorticoid with no AMMBE administration. Group C, was induced and treated with AMMBE at 400 mgkg-1for 14 days. While Group D, was induced with glucocorticoid and were treated with the standard drug (glibenclamide) at 2.5mgkg-1body weight of the rats daily&nbsp; for 14 days. Organ samples of liver, kidney and pancreas were collected for histopathological lesions Evaluation. The result showed that&nbsp; dexamethasone induced diabetes after seven (7) days of intraperitoneal administration of 2 mgkg-1 body weights with the glucometer readings in most of the albino rats up to and above 129 mgdL-1. The average blood sugar levels in induced groups (B, C and D) were 132.0±4.05, 129.0±1.41&nbsp; and130.0±2.93, respectively which were not statistically significant (P&gt;0.05). After administration of AMMBE, the average blood sugar level for group B (126.0±1.41) was significantly different (P&lt;0.05) from C (91.0±1.72) and D (87.0±2.97). Clinical signs of alopecia, dehydration, writhing, paw-licking were observed. There were massive losses of pancreatic cell mass grossly after induction with dexamethasone. Histopathological lesions observed&nbsp; ranges from no visible lesion in the control and glibenclamide treated groups to accentuation of hepatocytes in the AMMBE treated rats, and marked vacuolar degeneration of hepatocytes in periportal areas to centrilobular area with Kidney degeneration and multifocal coagulation&nbsp; necrosis of tubular epithelium in group induced with dexamethasone but untreated (group B) degeneration, multifoci coagulation and necrosis. The blood sugar levels post exposure to AMMBE and Glibenclamide showed reduction in the sugar levels. It could be concluded that dexamethasone has the potential of inducing diabetes when its use is prolonged and AMMBE has antidiabetic effect which could be fully explored.
