ANNONA MURICATA LINN. ETHANOLIC LEAF EXTRACT AMELIORATES REPRODUCTIVE COMPLICATIONS IN STREPTOZOTOCIN-INDUCED DIABETIC WISTAR RATS

Diabetes mellitus is an endocrine and metabolic disorder of humans and animals characterized by hyperglycemia and low blood insulin levels or insensitivity of target organs to insulin and it’s a major health problem affecting patient’s quality of life due to its many complications. Infertility is one of the major secondary complications in diabetes. Although numerous drugs have been used for intervention studies on diabetes-induced infertility worldwide, there are currently no treatments for diabetes associated infertility in humans. This study was performed to investigate the effects of Annona muricata ethanolic leaf extract (AMELE) on fertility of male diabetic rats and levels of blood glucose. Twenty male Wistar rats (150-200g) were randomly distributed into 4 groups (n=5) treated thus: CTRL (control), DNT, DT1 and DT2 (diabetic, single intraperitoneal injection, streptozotocin, 60 mg/kg). Group DT1 and DT2 received AMELE orally at 100 mg/kg and 200 mg/kg respectively daily for fourteen days. Data were analysed using ANOVA at α0.05. The animals were sacrificed after 2 weeks via thiopental injection and testicular weights were recorded. Fasting blood glucose was determined using a digital glucometer. Sperm count, motility, viability and morphology were assessed microscopically. Testes were histologically evaluated. The results showed that oral administration of AMELE at 100 mg/kg and 200 mg/kg to diabetic male rats for fourteen days significantly decreased blood glucose level and also ameliorated diabetes-induced decreases in sperm functions in streptozotocin-induced diabetic male rats.   &nbsp

Physicians’ Knowledge of the Glasgow Coma Scale in a Nigerian University Hospital: Is the Simple GCS Still Too Complex?

Objective: The Glasgow Coma Scale, GCS, is a universal clinical means of quantifying the level of impaired consciousness. Although physicians usually receive undergraduate and postgraduate training in the use of this scale in our university hospital we are aware of studies suggesting that the working knowledge of the GCS among practising physicians might not be adequate. Methods: We carried out a questionnaire-based survey across all specialties and levels of training of physicians in active patient care in a Nigerian university hospital. Results: Of the 100 physicians sampled, 98 correctly spelled out what the three-letter abbreviation, GCS, stands for. Ninety-three percent also conceded it to be an important clinical rating scale. However, only 55–89% of the participants correctly identified the three respective clinical variables, (eye opening, verbal response, and motor response), of the GCS. More particularly, the participants’ ability to itemize and correctly score all the respective components of each of the three clinical variables ranged from 0 to 35% across specialties and levels of training. Performance was best for the four-item eye opening variable and, worst for the six-item motor response variable. Conclusion: In our university hospital, practising physicians’ working knowledge of the GCS is inadequate and is dependent on the degree of the complexity of each of the three clinical variables of the scale

PLASMA LIPID PROFILE AND SOME BIOCHEMICAL INDICES IN DOMESTICATED GREATER CANE RAT (Thryonomys swinderianus temminck)

Some serum biochemical parameters and lipid profile indices were determined in eight male adult greater cane rats Thryonomys swinderianus Temminck, raised under intensive management system. Activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) in plasma were assayed spectrophotometrically, following venopuncture-blood collection and subsequent separation of plasma. Glucose, total protein, albumin and bilirubin as well as lipid profile indices such as total cholesterol, HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol, triglycerides and phospholipids concentration were also determined. In comparison with data from previous studies on wild and captive cane rats, our results indicate lower lipid profile indices and total protein. Activities of hepatic enzymes (AST and ALT) were also lower, while plasma glucose concentration was higher in this third generation greater cane rats. It is concluded that certain aspects of management system in domestication may have a profound influence on biochemical parameters most especially the lower LDL-cholesterol that reduces the risk of atherosclerosis (cardiac disease). This study, therefore offers baseline data for third generation intensively raised greater cane rats.Â

Antispermatogenic Activity Of Morinda Morindoides Root Bark Extract In Male Wistar Rats

To investigate the effect of the aqueous extract of the root bark of Morinda morindoides (Rubiaceae) on the reproductive activity of male Wistar rats, three groups (A, B and C) of six rats each were treated with 400,800 and 1600 mg/kg/day of Morinda morindoides root bark extract respectively for 28 days while 5mls/kg of distilled water was given to the control group D. At the end of the experimental period, animals were sacrificed and sperm characteristics, histology of the testes and epididymis were assessed. Morinda morindoides root bark extract caused a significant reduction (p<0.05) in sperm motility, a significant dose dependent reduction in the sperm count and a significant (p<0.05) dose dependent increase in morphological abnormalities of the spermatozoa of the treated rats. Histopathological evaluation of the testis and epididymis revealed varying degrees of degeneration and necrosis of the germinal epithelia cell of the seminiferous tubules and spermiostasis. Morinda morindoides root bark extract has significant anti-spermatogenic effects on adult male Wistar rats which could impair reproductive activities in these male Wistar rats. &nbsp

Bethune round table 2012: 12th annual conference: filling the gap

Background: Our aim was to highlight the impact of collaboration between 2 linked tertiary hospitals in Nigeria and India. Methods: We conducted a review of a collaboration between the Amrita Institute of Medical Sciences and Research Centre (AIMS), Kochi, India, and the University of Ilorin Teaching Hospital (UITH), Ilorin, Nigeria, to exchange personnel for the purpose of further training from August 2007 and December 2011. Results: One neurosurgeon, 2 pediatric surgeons and 1 orthopedic surgeon had additional exposure at AIMS for periods of 3 months to 1 year. Four neurosurgery and 3 pediatric surgery perioperative nurses have also been trained at AIMS for periods of 3 months. A pediatric surgeon was invited as faculty for laparoscopic training at Ilorin in 2010. The collaboration has resulted in exposure to surgical procedures not usually done in our centre. Our pediatric surgery unit has commenced laparoscopic surgery and pyeloplasty for pelvic ureteric junction obstruction in children. The orthopedic surgeon has commenced interlocking nailing and joint replacement. The neurosurgeon has successful done endoscopic third ventriculostomy and microscopic resection of brain tumour. Conclusion: This international collaboration has led to capacity building with significant impact on surgical services at UITH. An international collaboration and exchange program is a feasible and desirable strategy for technology transfer between technology-advanced settings and resource-constrained centres

SCREENING OF CRUDE EXTRACTS OF TWELVE MEDICINAL PLANTS AND “WONDER-CURE” CONCOCTION USED IN NIGERIA UNORTHODOX MEDICINE FOR ACTIVITY AGAINST MYCOBACTERIUM TUBERCULOSIS ISOLATED FROM TUBERCULOSIS PATIENTS SPUTUM

The antimicrobial activity of extracts of twelve Nigerian medicinal plant species and a “wonder cure” concoction [Epa –Ijebu]; used in traditional medicine for the treatment of tuberculosis and cough were screened for activity against Mycobacterium tuberculosis isolated from tuberculosis patient sputum and the control strains of M. tuberculosis (H37RV). Both ethanolic and aqueous solution of the extract of Allium ascalonicum, Terminalia glaucescens, Allium cepa and Securidaca longepedunculata (ethanolic extract only) at 0.05g/ml as well as aqueous solution of “wonder cure” concoction at same concentration inhibited the growth of M. tuberculosis. However at lower concentration of 0.2 µg/ml (critical proportion level of the control drug (isoniazide), M. tuberculosis was resistant to both aqueous and ethanolic extracts of the plants as well as the aqueous solution of the wonder-cure concoction. The phytochemical analysis of the plant extract and the Epa-Ijebu showed the presence of bioactive compounds: tannin, flavonoid, alkaloids, phlobatannin, anthocyanin, reducing sugar, saponin and anthraquinone. Our results offer a scientific basis for the traditional use of aqueous and ethanolic extracts of Allium ascalonicum, Terminalia glaucescens, Allium cepa, Securidaca longepeducunlata (ethanolic extract only) and aqueous solution of the “wonder cure” concoction at higher concentration against M. tuberculosis. However local herbs such as Nicotiana tabacum, Allium sativum, Aframomum melegueta, Aprus precatorius, Xylopia aethiopica, Tetrapleura tetraptera, Crinium jagus, and Garcinia kola were ineffective

Effects of palm kernel cake supplement on fatty acid profile and milk composition of lactating wad goats fed grass silage

The scarcity of quality feed and cost-effective supplements necessitates verifiable concentrate as a supplement for goat milk production. Palm Kernel Cake (PKC), an oil palm by-product rich in protein and energy, gradually replaced Prepared Concentrate (PC) in this study. This replacement's impact on milk composition and fatty acid profile in lactating WAD goats fed grass silage basal diet was assessed. Five supplement concentrates with varying PC: PKC ratios (100:0, 75:25, 50:50, 25:75, 0:100) were fed to 25 lactating WAD goats in a randomized setting of 5 animals per group. The replacement significantly affected (p<0.05) milk fat, protein, specific gravity, ash, and fat-corrected milk. The highest milk fat (2.17%) came from 100% PKC supplementation, while the lowest (0.77%) came from 25% PKC. Total solid fat values were not significantly affected. Fat Corrected Milk results mirrored the milk fat trend. The 100% PKC group had the highest crude protein (8.22%), while 25% and 75%PKC were not different (p<0.05). Fatty acid profile, expressed as total Fatty Acid Methyl Esters (FAMEs) g/kg, showed increased medium and long-chain fatty acids as PC was replaced. In conclusion, 100% PKC supplementation enhanced milk fat, while 50% PC replacement increased long-chain polyunsaturated fatty acids in goat mil

Agile manufacturing practices: the role of big data and business analytics with multiple case studies

The purpose of this study was to examine the role of big data and business analytics (BDBA) in agile manufacturing practices. Literature has discussed the benefits and challenges related to the deployment of big data within operations and supply chains, but there has not been a study of the facilitating roles of BDBA in achieving an enhanced level of agile manufacturing practices. As a response to this gap, and drawing upon multiple qualitative case studies undertaken among four U.K. organizations, we present and validate a framework for the role of BDBA within agile manufacturing. The findings show that market turbulence has negative universal effects and that agile manufacturing enablers are being progressively deployed and aided by BDBA to yield better competitive and business performance objectives. Further, the level of intervention was found to differ across companies depending on the extent of deployment of BDBA, which accounts for variations in outcomes

Interventions to reduce pesticide exposure from the agricultural sector in Africa: a workshop report

Despite the fact that several cases of unsafe pesticide use among farmers in different parts of Africa have been documented, there is limited evidence regarding which specific interventions are effective in reducing pesticide exposure and associated risks to human health and ecology. The overall goal of the African Pesticide Intervention Project (APsent) study is to better understand ongoing research and public health activities related to interventions in Africa through the implementation of suitable target-specific situations or use contexts. A systematic review of the scientific literature on pesticide intervention studies with a focus on Africa was conducted. This was followed by a qualitative survey among stakeholders involved in pesticide research or management in the African region to learn about barriers to and promoters of successful interventions. The project was concluded with an international workshop in November 2021, where a broad range of topics relevant to occupational and environmental health risks were discussed such as acute poisoning, street pesticides, switching to alternatives, or disposal of empty pesticide containers. Key areas of improvement identified were training on pesticide usage techniques, research on the effectiveness of interventions targeted at exposure reduction and/or behavioral changes, awareness raising, implementation of adequate policies, and enforcement of regulations and processes
