Abstract

Heavy metals are naturally occurring metallic elements that have a relatively high density compared to water. In most of the continent including Africa, the lack of food quality usually stand to be one of the major problem in which most of the food items are laden with lots of pollutants from heavy metals. Soil is said to be the reservoir of nutrients as well as pollutants. These pollutants have been implicated in causing lots of Health issues on human and Animals. Agricultural soil plays major role in food safety, food scarcity and food security, consumption of contaminated foods has serious implication on Human and Animals health. Heavy metals are potential environmental pollutants which are toxic to the human health. When present in an Arable land, they have the ability to bio-accumulate in the soil then to crops and eventually get to humans through food consumption. This study is able to evaluate the effect of heavy metals and risk analysis of arable farmlands in some selected local government areas of southern Taraba state (Donga, Wukari and Takum). All samples were processed, and heavy metals (Pb, Cd, Cr, Hg, and As) concentration were assayed using Atomic Absorption Spectrophotometry (AAS). The results showed that Chromium had a high concentration across all the studied areas with values ranging from 1.40 mg/kg to 2.25 mg/kg. However, Cadmium followed with values ranging from 0.04 mg/kg to 0.07 mg/kg and Arsenic with values ranging from 0.03 mg/kg to 0.06 mg/kg while Lead and Mercury had the lowest concentration of less than 0.03 mg/kg across the three LGAs. Ecological Risk Assessments parameters; Target Cancer Risk, Hazard Index (HI) and Estimated Daily Intake (EDI) were determined to assess the non-carcinogenic health risk. Takum recorded the highest levels of HM having the highest health risk followed by Wukari, whereas Donga had the lowest. Consistent use of crops harvested from the sampled location may pose a serious health challenge; bio-accumulation of toxicants in the soil across the studied areas may pose a health risk due to high concentration of heavy metals which are known to generate free radicals that may lead to oxidative stress and other cellular damages in humans.

Abstract

Hyperlipidemia is one of the principal factors underlying the risk for cardiovascular disease. Confirmatory evidence from animal, clinical, and epidemiological studies has clearly established the positive correlation. Allopathic antihyperlipidemic drugs are available but the side effects and contraindications. However, this study was designed to determine the haematological and antihyperlipidemic effect of ethanol leaf ex­tract of triherbal formulation (Mucuna pruriens, Phyllantus amarus, Securidaca longipeduculata) in wistar rat as a cheaper and readily available alternative. 46rats were grouped into normal, diseased, standard drug controls and test groups with seven rats each. quantitative phytochemical, haematological and antihyperlipidemic analysis were carried out according to standard methods. Results revealed presence of saponin, alkaloids, tannin, flavonoids, cardiac glycosides, phenolic with Total phenol exhibiting the highest values haematological results showed improving activities of the formulation on the erythrocytes, heamoglobins, lymphocytes and neutrophiles, this confers good effect on heamatological and immonological parameters especially at higher dose. In antihyperlipidemic activities, triherbal formulation significantly (p≤0.05) decrease the level of TC, TAG, LDL and improve upon HDL in both serum and liver homogenate effects thought to be via inhibition of cholesterol biosynthesis, absorption modification of lypogenic and lipolitic enzymes. Conclusively, the studies indicated triherbal formulation contain bioactive compounds with diverse biological activities such as immunomodulatory, inflammatory, heamatological and lipid profile regulating activities.

Abstract

In this study ALT and AST levels of experimental rats were significantly (p<0.05) increased from 11.91 ± 0.20 and 11.83 ± 0.40 to 57.23 ± 0.24 and 59.29 ± 0.50 respectively due to intoxication with aluminum chloride. When rats were treated with ethanol and aqueous extracts of Moringa oleifera at 100 mg/kg the levels of ALT dropped down to 11.62 ± 0.40 and 11.61 ± 0.17 respectively and the AST levels dropped to 11.39 ± 0.25 and 11.42 ± 0.15 respectively. A further increase in the concentrations of both extracts to 400 mg/kg resulted to a significant elevation of ALT 11.93 ± 0.17 (ethanol) and 11.94 ± 0.07 (aqueous) and AST 11.77 ± 0.25 (ethanol) and 11.78 ± 0.15 (aqueous). AST and ALT are common liver enzymes because of their higher concentrations in hepatocytes, but only ALT is remarkably specific for liver function. Therefore, an elevation in serum concentration of ALT is an indication of liver damage. The preliminary phytochemical screening for seed extracts of Moringa oleifera revealed that flavonoids, terpenoids, phenols, alkaloids, steroids and reducing sugars tannins were present in both the ethanol and aqueous extracts. Saponins and tannins were only found in the aqueous and ethanol extracts respectively. Experiments to observe for lethal conditions or changes in behavior showed no lethality or behavioral change at doses of 10, 100, 1000, 1600 and 2900 mg/kg bw. Weakness and drowsiness was exhibited at a dosage of 5000 mg/kg bw but no death occurred within 24 hrs. of administration.

Abstract

Determination of Malondialdehyde, MDA in blood plasma or tissue homogenates is one of the useful methods to predict the oxidative stress levels. The current study investigates the ameliorative effects of the seed extracts of Moringa oleifera on 35 albino rats induced with AlCl3 toxicity. Biomarkers of oxidative stress (Superoxide Dismutase, SOD; Catalase, CAT; Glutathione Peroxidase, GPx and Malondialdehyde, MDA were assayed. The plant seed extracts were shown to reduce the levels of MDA increased by AlCl3. AlCl3 caused decrease in (glutathione peroxidase) GPx levels as it causes MDA to significantly get elevated. The results showed that GPx decreased from 9.48 ± 0.86 to 6.68 ± 1.73 but upon treatments with 100 mg/kg bw of M. oleifera, GPx levels increased to 8.84 ± 0.86 (ethanol) and 8.96 ± 0.86 (aqueous). Increasing the concentrations of the extracts further increased the GPx levels while MDA were reduced.

Abstract

Background and Objective: Soil plays a major role in food safety and security. A major problem in most developing nations is a lack of food security and safety. The soil environment is a reservoir of nutrients as well as pollutants. This study eval_uated the health risk and heavy metals speciation of arable farmlands in Ardo-Kola, Zing and Yorro, Local Government Areas of Taraba State, Nigeria. Methodology: Three different soil samples from three Local Government Areas of Taraba State (Ardo-Kola, Zing and Yorro) were collected using sterile glass sample collection bottles measured at 5 cm depth. The collected soil samples were freed from unwanted materials by hand picking and air-dried for 5 days to remove excess moisture. The dried soil samples were crushed in with mortar and a pestle, the crushed soil sample was sieved through a 2 mm sieve made of stainless steel the sieved soil sample was further pulverized to a fine powder and passed through a 0.5-mm sieve. Heavy metals (Pb, Cd, Cr, Hg and As) concentrations were assayed using Atomic Absorption Spectrophotometry (AAS). Results: The results showed that Chromium had a high concentration with values ranging from 1.83 mg/kg to 2.62 mg/kg. While Lead and Mercury had the lowest concentration of less than 0.03 mg/kg across the studied areas. For ecological risk assessment parameters; target cancer risk, hazard index (HI) estimated daily intake (EDI) were all determined to assess the non-carcinogenic health risk. Ardo-Kola recorded the highest levels of HM, followed by Yorro, whereas Zing had the lowest concentration. Consumption of crops harvested from the sampled location may pose a serious health challenge; bio-accumulation of toxicants in the soil across the studied areas may pose a health risk due to high concentration of heavy metals which are known to generate free radicals that may lead to oxidative stress and other cellular damages in humans. Conclusion: Although most of the studied heavy metals were significantly present in all the analyzed soil except lead and mercury, their concentration in various soil samples across the studied areas exceeded the permissible levels as recommended by WHO except for Lead and mercury.

Abstract

Herbal combinations are widely used for the treatment of various diseases in the developing countries. Their ability in boosting the immune system is a function of Mineral constituents present. Currently available drugs have been associated with number of side effects. Herbal Combinations have often been used in traditional medicine systems like Ayurveda, unani, African, Chinese Medicine, and Western herbalism. Combination of herbs is superior with increased therapeutic efficacy to individual herb. Triherbal combinations consisting of (Mucuna pruriens, Phyllantus amarus and Securidaca longipedunculata) 1:1:1 ratio W/W. The study was aimed at investigating the phytochemical profile, in-vivo antioxidant activities, The quantitative Phytochemical result revealed present of Alkaloids, Flavonoids, Terpenoids, Saponins and glycosides with Total phenol having the highest values (111.67±0.23mg/GAE/g) followed by (92.50±0.14mg/GAE/g). Chemical profiling analysis showed two prominent compounds chlorogenic acid (78.2 %) and Caffeic acid (21.8%.).The results of Mineral compositions clearly indicated that triherbal fromulation is a rich sources of minerals indicating the presence of the following: Sodium(Na), Potassium(k), Magnesium(Mg), Calcium(Ca), Iron(Fe), Phosphporus (P), and Zinc(Zn) with Magnesium having the highest value of (830.5±0.0) and the least value zinc (9.8±0.14). Conclusively, These findings indicate that these triherbal formulations contain the essential minerals and bioactive compounds consequently exhibiting diverse biochemical activities, through multiple mechanism that could probably boost the immune system, making this formulation a potential therapeutic interventions for preventing liver damage and maintaining overall health.
