Oxidative status and spermatozoa kinetics of rooster semen in citrus juice-based diluent.

Poultry spermatozoa are prone to oxidative damage and adversely affect their fertility. Bioactive constituents of citrus fruit confer antioxidant enrichment on its juice and are candidates to combat oxidative load in poultry semen. Computer-assisted semen analyser and oxidative status were used to evaluate the potency of two tropical citrus varieties (sweet orange and tangerine) as natural diluents for rooster semen. Fresh and ripe sweet orange and tangerine fruits were obtained and processed into juices using a standard protocol and included in dextrose saline at 0%, 10%, 20%, 30%, 40%, 50% and 60% as semen diluent. Semen pool from 30 breeder roosters of 35-40 weeks of age was allotted randomly in triplicates to the different fruit juice-dextrose at 1:2 dilution rate and evaluated for 5 h at room temperature. Diluted semen, according to treatments, was evaluated for sperm kinetics using a computer-assisted sperm analyser, and seminal plasma was assayed for lipid peroxidation and total antioxidant activity. The result obtained shows that tangerine and sweet orange juice inclusion significantly (p < 0.05) enhance progressive spermatozoa motility and semen kinetics compared favourably with undiluted semen. The diluents had a proportionate increase in antioxidant activity with juice inclusion at 0 h and the antioxidant activity of 40%, 50% and 60% fruit juice-based diluents was higher than undiluted semen at 5 h. There was a reduced lipid peroxidation in juice inclusive diluents and increase lipid peroxidation rate in undiluted semen and 0% juice inclusion. In conclusion, tangerine and sweet orange juice inhibit lipid peroxidation in rooster semen and enhance progressive spermatozoa motility and maintain rooster semen kinetics.

Nutraceutical Effects of Justicia carnea Leaf Powder Supplementations on Performance, Blood Indices, Heat Shock Protein 70, Oxidative Deoxyribonucleic Acid Damage Biomarkers and Intestinal Microbes of Broiler Chickens, Under Tropical Condition.

The main reason preventing broiler chickens from reaching their genetic potential and hurting their performance in the tropics is heat stress. This study aimed to ascertain how Justicia carnea leaf powder (JLP) supplementation affects broiler chickens' performance, blood indices, antioxidant status, and gut microflora in tropical environments. A completely randomized method was used to assign 240 Cobb 500 broiler chicks to the experimental diets (6 replicates per diet, 10 birds per replication). Diet 1 included no supplement (negative control), diet 2 included 200 mg/kg vitamin C (positive control), diet 3 included 2,500 mg/kg JLP, and diet 4 included 5,000 mg/kg JLP. On day 42, the body weight gain (BWG) of the birds fed on diet 4 was significantly higher than those on diet 1. The packed cell volume, red blood cell count, and hemoglobin concentration of the birds fed on diets 3 and 4 were significantly higher than those of the control (P<0.05). The serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and cholesterol were lower in birds fed on diets 3 and 4, compared to those on diet 1 (P<0.05). The serum heat shock protein 70 (HSP 70) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were lower in birds fed on diets 3 and 4, compared to those on diet 1 (P<0.05). The lactic acid-producing bacteria (LAB) population was higher in birds fed on diets 3 and 4, compared to those on diet 1(P<0.05). However, the Coliform bacteria population was reduced in birds fed on diets 3 and 4, compared to those on diet 1. The 2,500 and 5,000 mg/kg JLP dietary supplementations enhanced BWG, improved erythrogram indices, and reduced blood AST, ALT, cholesterol, HSP 70, 8-OHdG, and caeca Coliform population but increased the caeca LAB population.

Indications and outcome of tracheostomy in Ilorin, North Central Nigeria: 10 years review.

BACKGROUND: The study aims to highlight common indications as well as outcome of treatment among patients with tracheostomy in Ilorin, North-Central Nigeria. METHODS: A review of clinical records of all patients with tracheostomy over a period of ten years (2002-2011), using the Theatre, Ward, ICU and the emergency register after approval from the ethical review committee. Data retrieved included; demographic profile, primary diagnosis, indication for tracheostomy, surgical technique, hospital admission and care outcome of management. All information retrieved input and analysed using an SPSS version 17.0 and data analyzed descriptively. RESULTS: Seventy-six patients had complete data for analysis, age range from 1-89yrs, and mean age of 41.9yrs. There are 48males and 28 females with M:F ratio of 1.6:1. Majority of the patients were in the 3rd-5th decade. About 47.4% had temporary tracheostomy. The commonest indication for tracheostomy is upper airway obstruction secondary to aerodigestive tract tumors in 60.5%, then trauma in 26.3%. The complications are higher among the under tens'. Out of the 36 temporary tracheostomy only 18 were successfully decannulated. The mean hospital stay was 22±2days. Overall 15% mortality was recorded. CONCLUSION: Common reason for tracheostomy is essentially same earlier documentation in developing countries, common among males, emergency type still most common, neoplasm, prolonged intubation and trauma are the commonest indications, its complication is still high among the under tens'. The outcome is good with 15% mortality due to the primary disease and not from tracheostomy.

Clinical Presentation and Outcome of Sinonasal Tumors in a Nigerian Tertiary Hospital - 6-year Review.

BACKGROUND: Sinonasal tumor is an uncommon tumor in Nigeria, but the burden of the disease in terms of morbidity and mortality is on the increase. The aim of this study is to evaluate the pattern of presentation and outcome of sinonasal tumor in our center. METHODOLOGY: This was a retrospective review of all the patients with sinonasal cancer seen in Ear, Nose, and Throat Department of the hospital between January 2008 and December 2013. The patients' biodata, clinical presentation, stage of the disease at presentation, identifiable risk factors, histopathological findings, and outcome were presented. RESULTS: A total of 22 patients were diagnosed with sinonasal cancer out of 71 patients (31%) with head/neck cancers during the period of study. There were 12 males (54.5%) and 10 females (45.5%) with a mean age of 51 ± 2.1 years. Epistaxis, nasal blockage, and discharge were seen in all patients though 41% of patients presented first to the ophthalmologist due to proptosis. Identifiable risk factors were exposure to wood dust (29%) and petrochemical products in (11%). Most patients presented first at advanced stages of the disease (82%). Histologically, well-differentiated squamous cell carcinoma was the most common (54.6%) followed by nonintestinal well-differentiated adenocarcinoma in 18.2% and plasmacytoma (9.1%). Chemoradiation was the mainstay of management in (38%) though 13.6% had total maxillectomy with postsurgical chemoradiation and 50.4% defaulted due to cost of management. CONCLUSION: Health education on early presentation and efforts at early detection of the disease are needed to achieve cure. Exposure to the identifiable risk factors should be reduced by protective measures. Easy access to radiotherapy at affordable price will surely improve the outcome of this disease.
