Reproductive Inhibition Effects Of Azadirachta Indica A. Juss And Ricinus Communis Linn. Seed Oils In Albino Female Mice
ABSTRACTRodents are the greatest vertebrate pest problem in developing countries causing substantial damage to structures, food, crops, industrial and domestic property. They also act as reservoirs and vectors of zoonotic diseases. The current method for controlling rodents is the use of rodenticides which are toxic to non target organisms, pollutants to environment and trigger resistance. In an effort to find eco-friendly alternatives to synthetic rodenticides, reproductive inhibition of Ric...
Effectiveness Of Pomegranate Punica Granatum L. Fruit Extract On The Sexual Function In Rats.
ABSTRACTThe worldwide prevalence of erectile dysfunction (ED) in 1995 was estimated to be 152 million males, and the figure is expected to rise to 322 million by the year 2025. The inability to achieve or sustain an erection and/or an inability to ejaculate is common among men over 40 years, where about 5% will experience ED and rates increase with age. Pomegranate (Punica granatum L.) has traditionally been believed to be of importance in male sexual disorder management. This investigation w...
Effect Of Different Management Systems On Haematological Parameters In Layer Chickens
ABSTRACTA study was conducted at the Department of Animal Science and Production, Sokoine University of Agriculture. The aim was to study the effect of different management systems on haematological parameters in layer chickens. Three management systems which are battery cage, deep litter and semi- intensive were involved. Ninety layer chickens, Rhode Island Red, eight weeks old were used. Thirty chickens were placed in each of the three systems. Seven chickens from each management system wer...
Assessment Of Anticholinesterase Contaminants In Ruvu River Using Cholinesterase Biomarker In African Sharptooth Catfish
ABSTRACTA cross sectional study was conducted to assess the extent of exposure of anticholinesterase contaminants in Ruvu river using cholinesterase biomarker in African Sharptooth Catfish. Questionnaire interviews were used to collect sociological data from 200 respondents, also Ellman‟s method and 5, 5‟-dithiobis-2-nitrobenzoic acid chromophore was used to establish cholinesterase activities in plasma and brain of 40 Claria gariepinus. The sociological findings showed that all responden...
Expression Of Tryp Anotolerant Quantitative Trait Loci In A Boran .•R~Sed Backcross Under Natural Tsetse Challenge
AbstractAfrican animal trypanosomosis (AAT) or Nagana is a transboundary disease with immensenegative impact in Agricultural development across 37 African countries, with 60M livestockat risk. Utilization of trypanotolerant breeds as a form of control may offer a viable andsustainable option following recent identification of nine trypanotolerant quantitative traitloci (QTL) with positive effects in an F2 cattle population ofN'DamaJ Kenyan Beran, undera challenge of 1180 clone of Tcongolence....
IMPACT OF GINGER (Zingiber official) on the intestinal, caeca microbial load and growth performance of broilers.
AbstractA study using ninety-nine day old Marshal Broiler chicks was conducted to investigate the effect of ginger root meal on growth, carcass and microbial population of broiler birds. The birds were randomly assigned to three treatments replicated three times in a Completely Randomized Design (CRD). Each treatment consisted of 33 birds with 11 birds per replicate. The birds were fed ginger root meals supplemented at 0%, 1.5% and 3.0% representing diets 1, 2 and 3 respec...
RENAL TISSUE AND SERUM IMMUNOGLOBULIN G OF HYPERTHYROID RATS
ABSTRACT There are several interactions between thyroid and kidney functions in health and disease states. Thyroid hormones affect renal development and physiology. Thyroid hormones have pre-renal and intrinsic renal effects by which they increase the renal blood flow and the glomerular filtration rate (GFR). Hyperthyroidism results in increase GFR as well as increased renin-angiotensin-aldosterone activation. This study was carried out to investigate changes in renal tissue and...
Comparative Nephroprotective Effects of Extracts of Buchholzia coriacea on some Biochemical Parameters in Carbon Tetrachloride-induced Toxicity in Rattus novergicus
Buchholzia coriacea (wonderful kola) is a medicinal plant that has been used worldwide as an alternative medication to promote human health. Comparative nephroprotective effects of crude seed powder, aqueous and methanolic extracts of B. coriacea in hepatotoxic rats was investigated for 56 days. The crude powder (BCCP), aqueous extract (BCAE) and methanolic extract (BCME) significantly reduced (p
Hypoglycaemic and Hypolipidemic Effects of Black Brand of Lipton Tea (Camellia sinensis) on Normal Male Albino Rats
Recently, considerable attention has been focused on dietary supplements that possess hypoglycaemic and hypolipidemic properties in lieu of the synergistically synthesized drugs like statins and metiform which have been proven to have adverse effects. This present work was carried out to study the potential effects of Lipton tea aqueous extract (LTAE) on normal male albino rats. 36 six male Wistar rats weighing 115 - 150g were assigned into four main groups; each group was divi...
CHANGES IN SOME HEMATOLOGICAL PARAMETERS IN DIABETIC RATS TREATED WITH LEAF EXTRACT OF TERMINALIA CATAPPA (INDIAN ALMOND) AND NON-STEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs)
AbstractThe changes in some haematological parameters in alloxan-induced diabetic rats treated with Terminalia catappa leaves extract and Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) was studied. 54 male albino wister rats were selected into nine (9) groups of six (6) rats each. Diabetes was induced intraperitoneally to the test groups with 150mg/kg BW of alloxan monohydrate and the experiment lasted for 14 days. Group 1 was control which received 1mg/kg of deionized water, group 2 was extr...
Effects of Organic Turmeric on Liver Integrity and Oxidative Stress of the Brain in Rabbits Exposed to Ultraviolet Radiation
This project investigated the effects of organic turmeric on the liver and oxidative stress of the brain in rabbit acutely exposed to ultraviolet radiation. Thirty five weaned rabbits between 8-10 weeks of age, randomly allocated to control (A) and five (5) treatments: B, C, D, E and F were used for this experiment. Treatment A: fed organic feed without turmeric inclusion and not radiated, Treatment B: fed diet supplemented with 2% turmeric as its constituen...
Sampling for Insects
Insects are the most successful and enduring life form on earth and are known to have existed for over 400 million years. They are the most dominant multicellular life form on earth and are represented all over, from the poles to the equator, from the sea surface to the highest peaks and from the deserts to rain forests. It is estimated that insects comprise about half of the earth’s 1.5 million known species (Chapman, 2013; McGavin, 2007). Gullan and Cranston (2014) stated that ...

INTRODUCTIONThere has been world wide explosion of infectious diseases with emerging diseases such as HIV/AIDS pandemic as well as old diseases like cholera, tuberculosis, dengue, or malaria. These infectious diseases are on a sudden increase due to many factors amongst which; climate change, transformation of ecosystems, socio-economic problems and Public health systems deterioration in many countries in the world. Generally, numerous diseases have emerged and re-emerged (Sanjeev et al., 201...
EFFECTS OF STAGE OF LACTATION AND PARITY ON BLOOD VOLUME AND MILK YIELD IN WEST AFRICAN DWARF SHEEP
ABSTRACTA study on the effects of stage of lactation and parity on blood volume and milk yield in West African Dwarf sheep was carried out using (12) lactating West African Dwarf sheep for twelve (12) weeks of lactation. In the second week of the experiment, the dams were weighed using pocket balance scale. Evans blue dye solution was injected into the animal through the jugular vein and waited for 10-15 minutes before bleeding the animal through the same media. The milk yield were measured i...
