Effect of Nutrition on the Birth Weight and Multiple Births of Trypanosome Infected Female Rattus Norevegicus

Effect of Nutrition on the Birth Weight and Multiple Births of Trypanosome Infected Female Rattus Norevegicus

Nutritional status of female reproducing animals before and during gestation affects the offspring. Carbohydrate, protein and micronutrients deficiencies in female either before conception or in early pregnancy have been implicated in causing low birth weight in offspring (Galloway et al., 1994).

Consumer Preference for Swine Offals and Its Health Implications in Kumasi, Ghana

Consumer Preference for Swine Offals and Its Health Implications in Kumasi, Ghana

Global meat consumption rate had doubled in most countries over the last five decades. In Ghana, total animal production has also increased over the last decade with consumption of pork and its offals becoming prominent. Therefore this study aims to evaluate factors that influence consumer preference for pig offals and the associated public health risks. One hundred (100) respondents in the Kumasi Metropolis were randomly selected through structured questionnaires and samples of offals randomly collected, sectioned, processed and examined for any histopathological indicators. Data collected were analyzed through the use of descriptive statistical tools. The results showed that edible offal preferential consumption exist within the increasing demand and value supply chain with the liver (32%) and stomach (23%) being the most preferred offal. Factors such as nutritional value, delicacy, availability, cost and level of education are noted to influence the purchasing power and preference of consumers. The consumers are less conscious regarding the risks stemming from the common zoonotic diseases and health concerns. Histological assessment of the most preferred offals (liver) showed no remarkable histopathological changes. Based on this, the preference for pig livers may not be associated with considerate health risk.

An Expository on Malaria Diagnostic Techniques in the Tropics

An Expository on Malaria Diagnostic Techniques in the Tropics

Other available methods include:- Fluorescence microscopy, which has improved the sensitivity, but not the specificity of diagnosis, Polymerase Chain Reaction (PCR) diagnosis, which is sensitive for all four species of human Plasmodium spp. and can be expected to exceed the sensitivity of microscopy; but poses time and technical problems, Immunochromatographic dipsticks that offer the possibility of more rapid, non-microscopic methods for malaria diagnosis, thereby saving on training, time and Self-diagnosis. Kits for self-diagnosis by travellers in remote areas has been developed.

In Vivo and in Vitro Evaluation of the Inhibitory Effect of Some Medicinal Plant Extracts on Haemozoin Concentration

In Vivo and in Vitro Evaluation of the Inhibitory Effect of Some Medicinal Plant Extracts on Haemozoin Concentration

The plant extracts similarly exerted significant reduction in the haemozoin concentration. Nevertheless, Alstonia boonei extract was the most effective in haemozoin reduction at 0.00 significant level (p<0.05). Of all the therapeutants (chemical and plant extracts) tested, Alstonia boonei stem back extract most significantly reduced haemozoin production (p<0.05), indicating its potential for use in novel anti-plasmodium and antimalaria drug formulation.

Clinical Chemistry and Haematological Assessment of Quail Egg-Pretreated Acetaminophen-Induced Hepatotoxicity in Rats

Clinical Chemistry and Haematological Assessment of Quail Egg-Pretreated Acetaminophen-Induced Hepatotoxicity in Rats

This study investigated the possible hepatoprotective effect of quail egg solution on acetaminophen intoxicated rats. Thirty adult rats of mixed sexes were assigned into five groups of six per group. The rats in groups 2, 3, and 4 were pretreated with 30, 15, 7.5 mg/ml ad lib respectively of quail egg solution for 7 days before intoxication with 2000 mg/kg acetaminophen. Rats in group 5 were not pretreated but intoxicated with 2000 mg/kg acetaminophen (negative control) while the group 1 rats were neither pretreated nor intoxicated and served as positive control. Fourty eight hours post induction, blood for some biochemical and haematological analysis was collected and the remaining rats treated until 14th day when the rats were humanely sacrificed and vital organs (liver and kidney) collected for histopathology. The results showed that the ALT activity of 30 mg/ml pretreated rats were significantly (p<0.05) lower than those of the negative control rats. Significant (p<0.05) increases were seen in the RBC, WBC, PCV and Hb levels of quail egg pretreated rats when compared with the negative control. However no significant (p>0.05) changes were seen in AST activity, MCHC and MCH levels of both the test groups and the controls. Histomorphometry examination revealed less severe vacuolar degenerative changes in the liver of 30 mg/ml pretreated rats when compared to the rats of other intoxicated groups. It was concluded that quail egg at the concentration of 30 mg/ml ameliorated hepatotoxicity and improved haematologic indices of acetaminophen-induced toxicity in rats.

Effect of  Meloidogyne Incognita  (Root- Knot Nematode) on the Development of Abelmoschus Esculentus (Okra)

Effect of Meloidogyne Incognita (Root- Knot Nematode) on the Development of Abelmoschus Esculentus (Okra)

ABSTRACT: Seedlings of Okra Abelmoschus esculentus were inoculated with different numbers of egg masses (0, 4 8 and 12) of Meloidogyne incognita. The different inoculums elicited varied reactions on the Okra plants. Root galls increased progressively and significantly with increased levels of inoculum. At 0 (zero) inoculum level no root gall was observed. At low inoculum levels, 4 and 8 egg masses, the plants performed seemingly better than the control (in terms o plant dry weight, f ower and fruit production). At high inoculum levels very low mean yields of the above parameters were recoded when compared to the control. The implications of enhanced per ormance observed at low inoculum levels on experimental crops are discoursed.

Optimum Dietary Protein Requirement of Genetically Male Tilapia (Oreochromis Niloticus) Cultured in Floating Hapa System

Optimum Dietary Protein Requirement of Genetically Male Tilapia (Oreochromis Niloticus) Cultured in Floating Hapa System

The study was conducted to investigate the optimum dietary protein level needed for growing genetically male tilapia, Oreochromis niloticus. Diets containing crude protein levels 40, 42.5, 45, 47.5 and 50% were formulated and tried in triplicates. Test diets were fed to 20 fish/1m3 floating hapa at 5% of fish body weight daily for 24 weeks. Survival of fish was not affected by dietary protein levels. Growth rate varied inversely with dietary protein levels to a maximum at 40%. Protein utilization and turnover decreased with increasing protein levels in diets. Quadratic regression analysis of growth indices against protein inclusion levels indicated that the optimum dietary protein required for maximum growth was 40%.This result also paralleled the least values of protein and calorie deposited for 40% protein level whereas the other levels were significantly (p<0.05) higher. The study concludes that 47.5% and 50% protein levels may depress tilapia growth and feed utilization, while 40% protein gave optimum growth.
