ABSTRACT
Daucus carota (carrot) seed is used medicinally in the treatment and management of diabetes mellitus, in whichoxidative stress and hyperlipidemia are associated complications. The study evaluated the antioxidant andantihyperlipidemic effects of aqueous seed extract of D. carota aqueous extract (AQEDCS) in triton ×100-inducedhyperlipidemic mice. The in vitro antioxidant activities of the extract (0.2–1.0 mg/ml) were evaluated using totalantioxidant capacity, 2,2-diphenyl-1-picrylhydrazyl, nitric oxide, and ferric ion scavenging. In vivo antioxidantand antihyperlipidemic properties of AQEDCS extract were evaluated using triton ×100-induced oxidative stressand hyperlipidemia in mice. AQEDCS contains alkaloids, tannins, phenols, and produced significant antioxidanteffects in vitro compared to Vitamin C. AQEDCS significantly (P < 0.05) decreased levels of plasma cholesterol,triacylglycerol, low-density lipoprotein, coronary artery, cardiac, and atherogenic indices and increased circulatinghigh-density lipoprotein levels when compared to untreated hyperlipidemic mice. AQEDCS significantly (P < 0.05)decreased the level of malondialdehyde compared to untreated hyperlipidemic mice. AQEDCS and simvastatindecreased (P < 0.05) reduced glutathione concentration in plasma, with no difference (P > 0.05) in the liver of micecompared to untreated hyperlipidemic mice. Similarly, no significant difference (P > 0.05) was observed in plasmanitrite levels, superoxide dismutase, and glutathione S-transferase except in AQEDCS mice that received 100 mg/kgbody weight dose of AQEDCS extract when compared with non-induced control. The results indicated that AQEDCSpossesses antioxidant and antihyperlipidemic effects, and could complement antioxidant defense system in vivoduring oxidative stress as well as prevent further complications that could arise from hyperlipidemia during its usagefor diabetes mellitus treatments.
ABSTRACT
Background: Amputation is one of the oldest known surgical procedures. It has been one of the modalities of applying judgment and treatment. Its method and indications has evolved over time. Modern amputation is regarded as a part of treatment rather than failure of treatment. Amputation is the removal of a limb or part of a limb through on or more bone. When through a joint is referred to as disarticulation. Data on the profile and pattern of amputation in Liberia will add to the body of knowledge. Aim and Objectives: Is to describe the pattern of limb of amputations in Liberia. Also to describe the anatomical variations of limb amputations in Liberia. Patients and Method: A retrospective study of all patients that underwent limb amputation surgeries in the John F Kennedy Memorial (JFK M), Hospital , Monrovia Liberia between January 2010 to December 2015. Results: 100 patients had limb amputations between 2010 and 2015. Males(73) to female(27) ratio were 2.4:1. The age range was 9 - 91 years. Mean age was 42.9 years. The indications for amputations were Trauma 24%, Diabetes 29%, Gangrene (6%), Chronic ulcer (25%), Tumour (5%). Below knee(47%), Above Knee(45%), Below elbow(2%), Above Elbow(2%), Knee Disarticulation(2%), and Big Toe Disarticulation(2%). Conclusion: The profile of Limb amputation in Liberia is not very different from what is obtaining in the region. However the limitations of histology and other investigative procedure have affected the accurate diagnosis of certain conditions like tumours

Background: Correct estimation of intravascular volume is crucial in critically ill and traumatized patients. Measurement of the central venous pressure (CVP) is invasive and time consuming. Studies have shown that inferior vena cava diameter (IVCD) correlates with CVP. Sonographic assessment of IVCD and its respirophasic changes (collapsibility index; CI) is a non-invasive, quick and reliable means of estimating CVP and hence, intravascular fluid volume. Data on such studies are scanty among adult Nigerians. Aim: To establish normograms of IVCD and CI for healthy adults in Benin City, Nigeria as well as determine the relationship of IVCD and CI with height, weight, body mass index (BMI), age and gender. Method: Four hundred apparently healthy adult volunteers were prospectively studied by means of ultrasound. Demographic data and BMI were obtained. The IVCD was measured during inspiration, expiration and sniff. The CI was subsequently calculated for each subject. Statistical Package for the Social Sciences (SPSS) version 17.0 was used for data analysis including tests of significance. Probability values less than or equal to 0.05 were considered significant. Results: The mean IVCD in this study was 6.1±2.2mm and 13.0±4.0 mm for inspiration and expiration respectively. The mean CI was 49.7±0.5%. There was no statistically significant correlation between IVCD and CI with height and BMI. Conclusion: This study has determined normal IVCD and CI reference range for healthy Nigerian adults. The CI is independent of height, weight, BMI and gender. Since the CI is not dependent on physical attributes and gender, it may serve as an objective tool for monitoring the fluid status of patient
