The parasitic fauna of freshwater fishes the Warri River, Delta State, Nigeria, with reference to their prevalence, intensity and differences in metazoan parasites between fish sexes, was investigated. A total 85 samples comprising 21 Tilapia zillii (Cichlidae: Perciformes), 23 Synodontis clarias (Mochokidae: Siluriformes), Chrysichthys nigrodigitatus (Claroteidae: 16 Hepsetus odoe (Hepsetidae: Characiformes) 2 Clarias anguillaris (Clariidae: Siluriformes) collected from were subjected...

The fruit extract of Dacryodes edulis (D. edulis), the African pear or plum, a tree indigenous to humid tropics has been used for managing wounds, skin diseases, sickle cell anaemia, dysentery and fever in some nations. In South Eastern Nigeria, 'herbal doctors' include its marshed decoctions administered diabetic patients. However no scientific substantiation their claim use exist literature. Hence, need evaluate antidiabetic hypolipidaemic activity hexane extracts D. alloxanised animal...

The survival of land snails in an adverse environmental condition depends on the integral physiological, morphological and behavioural adaptations. These adaptations are essential understanding species-specific habitat requirements predicting their responses. In this study, monthly periodic patterns eco-physiological adaptation snail, Achatina achatina Nsukka tropical agro-ecosystem were assessed from December 2012 to July 2013. Standard methods employed sampling snail determination water...

Phytochemical screening of the methanolic fruit extract Solanum macrocarpon was performed using standard method. Eighteen male albino mice, assigned into six groups (n=3) were used to determine acute toxicity (LD50) extract. Haematological effect determined forty eight adult rats four (A-D; n=12). The treatment received daily oral administration at doses 400, 800 and 1600 mg/kg body weight (bw) respectively for 21 days. phytochemical revealed presence flavonoids, saponins, alkaloids,...

The proximate composition, functional and physical properties, as well sensory evaluation of breads based on blends wheat &lsquo;orarudi&rsquo; (Vigna sp) flour were investigated. Batches separately put in a container subjected to natural lactic acid fermentation deionized water ratio 1:3 (w/v) at 28 &plusmn; 2&deg;C for 24 h. fermented samples manually dehulled the cotyledons dried 55 drought&nbsp; air oven, hammer milled into (500 &micro;m mesh screen) stored refrigerator (5 2&deg;C)....

Abstract In this study, African Catfish (also known as Sharptooth Catfish) Clarias gariepinus were exposed to sublethal concentrations of fenthion 2.0, 4.0, and 8.0 mg/L for 21 d allowed recover 7 investigate the potential hematological changes. Whole blood was sampled on days 1, 7, 14, postexposure after a 7-d recovery period. During exposure, caused reduction in red cell counts, hemoglobin concentration, packed volume. There an increase white counts but no significant difference mean...

The bacteriological quality and levels of essential mineral elements organic acids were evaluated in 33 randomly selected bottled/packaged water samples produced marketed Southeastern Nigeria. microbiological assay, determined using American Public Health Association (APHA) standard methods. distinguishing characteristics the microorganisms identified their psychotropic growth capabilities, motility at 37&deg;C, air, negative phenylalanine, deaminase, positive urease, catalase, oxidase...

SUMMARYChromosomes from the bone marrow of Mabuya affinis, M. maculila-bris maculilabris (Grey) and quinquetaeniata sharica (Sternfield) were studied several male female animals. All species have same chromosome number 2n = 32. The first five chromosomes in three account for almost 70% genome (by lenght), appear characteristic to skinks generally. It is suggested that variation arose by centromeric fissions fusions, including pericentric inversions.

Apoptosis is the process of programmed cell death (PCD) which usually occurs in multicellular organisms.In this case, biochemical events leads to morphological changes and death.Some these are blebbing, shrinkage, nuclear fragmentation, chromatin condensation chromosomal Deoxyribonucleic Acid (DNA) fragmentation.Apoptosis however distinct from necrosis a form traumatic that results acute cellular injury.Apoptosis generally confers advantages during an organism's life cycle.One can be seen...

Seasonal histological features of the testis and epididymis were studied in male A. agama from July l990 to June, 1992 at Ile-Ife, Nigeria.  Testis weights showed no significant difference (P > 0.05) dry rainy seasons, but generally low August January. Whereas seminiferous tubule diameter epithelia heights seasonal variation (p 0.05), epididymal varied seasonally < 0.001). Although males full breeding condition caught all through months, such more prevalent April July. Females with eggs or...

Dichlorvos is an organophosphate pesticide used for the control of pests in crops and stored products, while primextra a commercial herbicide formulation generally agriculture weed control.

In this era of climate change, some biological conservationists' concerns are based on seasonal studies that highlight how wild birds' physiological fitness interconnected with the immediate environment to avoid population decline. We investigated biometrics correlated stress parameters adult Village Weavers (

Mucuna sloanei is an annual leguminous plant widely used among the various ethnic groups in Nigeria. The effects of aqueous M. seed extract on body weight and some biochemical parameters 48 normal male Rattus novergicus (albino rats) were investigated for 28 days. rats divided into control group (A) which received distilled water treatment (B, C D) that oral administration 100, 200 400 mg/kg extract, respectively.
