Toxicological Effects of Overdose of Some Herbal Bitters Commonly Consumed in South Southern Nigeria

Abstract: Aim: The aim of this study was to evaluate the toxicological effects of overdose of Action Bitters and Goko Cleanser on hepatic, renal and haematological indices. Methodology: Thirty-five (35) male albino wistar rats were divided into seven groups of five rats each. The six treatment groups were given the herbal extracts for four weeks while the control group was given distilled water. The study was carried in the Department of Medical Laboratory Science, Rivers State University, Port Harcourt, between June and August, 2019. Biochemical parameters were assayed using Mindray biochemistry analyzer while haematological parameters were assayed using Sysmex analyzer. Original Research Article Elechi-Amadi et al.; AJMPCP, 3(2): 35-39, 2020; Article no.AJMPCP.55420 36 Results: There were significant increases in hepatic parameters (AST, ALT and ALP), renal parameters (Urea and Creatinine) and significant decreases in haematological indices (PCV and HB) in the treated groups, except for the normal dose weekly treatment group. Conclusion: Long-term use or overdose of the herbal mixtures can lead to alterations in hepatic, renal and haematological indices.

Theoretical modeling of horizontal-vertical loading of circular foundation in the offshore Niger Delta of Nigeria

Abstract: Theoretical modeling on the performance of offshore circular foundation installed on clay and subjected to combined horizontal-vertical load in the Niger Delta has been attempted. Analytical methods of Skempton, Brinch Hanson, and Vesic were used to evaluate concentric vertical loads on offshore piles. Horizontal forces, H were evaluated for varying wave heights on circular piles of 1.0 to 2.0 m diameters using available meteorological and oceanographic offshore records. The results revealed that sliding failure commenced when the ratio of vertical load to footing area and undrained shear strength, V/Asu assumed negative values (i.e. at H > 0.082 Asu). The maximum mean vertical load is 6.107 Asu, and to guide against the occurrence of bearing capacity failure by sliding, V > 0.75H for cases where the ratio of footing depth to breadth ratio is lesser than one, (D/B 0.70H when footing depth to breadth ratio is greater than one (D/B > 1.0).

Symptomatic Hypernatraemia Secondary to Ingestion of Poorly Constituted Oral Rehydration Solution – A Case Report

Abstract: Aim: Hypernatremia is a recognized complication of poorly constituted Oral Rehydration Solution (ORS) use that can cause neurological manifestations which require careful but often challenging management to prevent morbidity and mortality. Herein we report a case of symptomatic hypernatremia in a 2-year-old boy following ingestion of poorly constituted Oral Rehydration Solution (ORS) and highlight challenges in management. Presentation of Case: This is a case report of a 2-year-old male who presented with a four-day history of vomiting and fever. He received four litres of hyper-concentrated ORS (1 packet of ORS to 0.7 l of water) prior to presentation. At presentation, he was lethargic and subsequently lapsed into unconsciousness. He also developed focal and generalized seizures. Serial serum electrolytes testing showed hypernatremia which ranged from 157-161 mmol/L in the first 48 hours of admission for which appropriate intravenous fluids were given. Serum sodium levels gradually returned to normal (140-142 mmol/L) with treatment. He subsequently regained full consciousness after four days in a coma and was discharged home in satisfactory clinical condition. Conclusion: This case is being reported to highlight the important role of proper history taking, careful fluid and electrolyte monitoring in the diagnosis and care of this condition and emphasise on adequate education of caregivers by clinicians and the mass media on appropriate preparation of ORS.

Back-navigation string matching algorithm (bsma)

Abstract: This research took a comparative analysis on string matching algorithms. The study focused on developing an efficient algorithm (Back-navigation String matching algorithm) which will be used for large documents. The algorithm whilst compared to the existing system introduced a pattern of search which was done backwardly, from the last character to the first. The existing system considered more number of shifts which was slow and has a bad character shift. The research aimed at developing an efficient string matching for large documents sorting. The research methodology adopted for this project research is the verification and validation methodology which perform its test in a reverse manner so the software developer can at each stage review its step. The proposed system was executed and produced a result which compared with the existing system was termed efficiency. The system introduces a faster means of searching which starts form the last character to the first. The developed system which is the efficient string matching algorithm was analyzed and displayed a faster means of searching documents and is termed efficient because of its computing speed of 2 milliseconds while the naive algorithm which ran with the computing speed of 154 milliseconds for a total number of 5000 characters.

Recent trends in field crop pest management in Nigeria – A review

Abstract: With the avalanche of insecticides and their misuse especially in developing countries, it has become important to review all methods of insect pest management used in Nigeria, starting from the era of polyculture-crop diversity and to the present day intensive agricultural practices geared towards improving increased agricultural productivity, the great diversity of crops has attracted new and important pest problems. Recent trends in agricultural field pest management in Nigeria cover the use of chemicals, plant extracts, improved plant varieties, cultural control methods and the use of biological agents. Initially the predominant use of insecticides in the Nigerian agriculture was in the control of insect pest of tree crops such as cocoa and kola so much so that by the mid 1950s the use of sprayers and gama - HCH was well established in control of insect pests of major crops.
