Background: Plants like herbs has been extensively used for different kinds of nutritional and medicinal purposes, however, scientific studies has shown that these medicinal plants may have deleterious effects on some vital organs of the body if not taken at the recommended doses. Thus, there is a need for safety evaluation of these plants to ascertain their actions on organ’s physiological functions. This present study evaluates the effects of ethanol seed extract of Picralima nitida on the haematological examines and some enzymes activities in the serum of albino rats. Twenty-five rats were equally randomized into five groups. Group A (control) received distilled water while graded doses (50, 100, 150 and 200 mg/kg body weight) of ethanol seed extract of Picralima nitida were administered to rats in groups B, C, D and E respectively for 14 days. Haematological studies were carried out on the rats’ blood samples while concentrations of total protein, albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea, and creatinine were measured in the serum. Results: Result obtained revealed that treatment of rats with various graded doses of ethanol seed extract of Picralima nitida caused marked increase in urea and creatine compared to the control. Rats treated with 150 and 200mg/kg bw of the extract showed marked elevation in serum levels of the enzymes suggesting that the extract may have adverse effects at this dose. There was also a marked elevation in serum electrolytes of rats treated with 150 and 200mg/kg bw of the extract. Rats treated with low concentrations (50 and 100 mg/kg bw) of the extract demonstrated no marked differences or alteration in haematological parameters, protein profile and enzyme activities in the serum. Conclusion: The results of this study indicated that consumption of ethanol seed extract of Picralima nitida as a therapeutic treatment is nontoxic at lower dose. However, if taken at high doses, the extract might be detrimental to some vital organs and systems.

AbstractThe prevalence of type 2 diabetes mellitus (T2DM) is expected to increase rapidly in the next decades, posing a major challenge to societies worldwide. The emerging era of precision medicine calls for the discovery of biomarkers of clinical value for prediction of disease onset, where causal biomarkers can furthermore provide actionable targets. Blood-based factors like serum proteins are in contact with every organ in the body to mediate global homeostasis and may thus directly regulate complex processes such as aging and the development of common chronic diseases. We applied a data-driven proteomics approach measuring serum levels of 4,137 proteins in 5,438 Icelanders to discover novel biomarkers for incident T2DM and describe the serum protein profile of prevalent T2DM. We identified 536 proteins associated with incident or prevalent T2DM. Through LASSO penalized logistic regression analysis combined with bootstrap resampling, a panel of 20 protein biomarkers that accurately predicted incident T2DM was identified with a significant incremental improvement over traditional risk factors. Finally, a Mendelian randomization analysis provided support for a causal role of 48 proteins in the development of T2DM, which could be of particular interest as novel therapeutic targets.

The toxic effect of diclofenac (DCF) sodium and Ciprofloxacin (CIP) on gene expression of cytochrome P450 oxidase (CYPs) and the histology of liver and kidney of male albino rat has been evaluated in this study. DCF and CIP were chosen since they are inhibitors for specific CYP enzymes. Thirty-five adult male albino rats were divided into 7 groups of 5 animals each (A, B, C, D, E, F and G) and were treated orally with drugs for 21 consecutive days. Group A served as the control while B and C were treated with 5.3, 10.6 mg/kg body weight (bw) DCF sodium and groups D and E were treated with 40 and 80 mg/kg bw CIP, respectively. Groups F and G were treated with a mixture of the low and the high doses of both drugs, respectively. Both drugs significantly downregulated the mRNA expression of CYP1a2, CYP3a4 and CYP2c9. They caused hepatorenal histological changes. In the liver, massive fibrosis, necrosis, inflammatory cell infiltration with hemorrhages and hydrophilic degeneration have been observed. A massive tissue injury with glomerular and tubular damages due to sever necrosis, degeneration of concomitant inflammatory cells and blood vessels congestion have been shown in renal tissues. Although DCF and CIP are still used as therapeutic drugs, their use should be limited as their chronic administration induces a toxic effect on human health.

The concurrent use of tramadol and diclofenac may increase hepatotoxic risk due to their individual hepatotoxic effects. This study assessed the hepatotoxic effect of tramadol-diclofenac administration in albino rats. Twenty-four adult male albino rats (200-220g) randomized into four groups were orally administered with tramadol (12mg/kg/day), diclofenac (6mg/kg/day) and tramadol-diclofenac for 14 days respectively. The rats were anesthetized, blood samples were collected and evaluated for serum liver function and lipid parameters. Liver samples were weighed and evaluated for biochemical parameters and histology. The effects of tramadol-diclofenac on the body and liver weights did not differ significantly (p>0.05) when compared to control. Also, effects were not significant (p>0.05) on blood glucose, and serum cholesterol, triglyceride, low and high density lipoprotein cholesterol levels when compared to control. Liver and serum levels of aminotransferases, alkaline phosphatase, lactate dehydrogenase, gamma–glutamyl transferase, conjugated bilirubin and total bilirubin increased significantly in rats treated with tramadol (p<0.05), diclofenac (p<0.01) and tramadol-diclofenac (p<0.001) when compared to control. Furthermore, significant decreases in liver catalase, glutathione, superoxide dismutase, glutathione peroxidase levels with significant increases in malondialdehyde levels occurred in rats treated with tramadol (p<0.05), diclofenac (p<0.01) and tramadol-diclofenac (p<0.001) when compared to control. Hepatocyte necrosis was observed in rats treated with tramadol-diclofenac. Tramadol-diclofenac may increase hepatotoxic risk at doses used for this study.

Safety evaluation of Waltheria indica Linn. root was carried out in Wistar rats. Twenty adult male Wistar rats were randomly divided into four groups (n=5); A–D. Group A served as control group while groups B, C and D were administered with 200, 400 and 800 mg/Kg of crude ethanol extract of Waltheria indica Linn. root. After 28 days of administration, the rats were sacrificed and blood samples were collected and serum prepared. Haematological and biochemical parameters, as well as serum electrolyte were determined according to standard procedures. The 200 mg/Kg of Waltheria indica Linn. root caused the highest percentage increase in body weight. The kidney was also significantly increased at 400 mg/kg. The total WBC and lymphocytes counts were significantly increased at 400 mg/kg. The serum levels of ALT and chloride were significantly increased at 800 mg/kg. Waltheria indica Linn. root also caused hepatic necrosis and renal tubular degeneration in Wistar rats. Therefore, Waltheria indica Linn. root should be used with caution especially at higher dose despite its therapeutic potentials.

Background. Organochlorine pesticides (OCP) are persistent organic pollutants that have been implicated in causing several deleterious effects in humans. These are known neurotoxins in high doses, but the role of environmentally acquired OCPs in the body to induce seizures in children has not been investigated yet. Objectives. To assess the serum levels of OCPs in children aged 2–12 with idiopathic seizure and to find out any association between the two are our objectives. Methods. It was a cross-sectional pilot study. Twenty developmentally normal children aged 2–12, presenting with idiopathic generalized seizures, were recruited. Twenty age-matched controls without any history of seizures were also taken. Their serum levels of α, β, and γ hexachlorocyclohexane (HCH); and aldrin; dieldrin; p,p-dichlorodiphenyltrichloroethane (DDT), o,p-DDT, and p,p dichlorodiphenyldichloroethylene (DDE); and α and β endosulfan were analysed using gas chromatography (GC). Mann-Whitney U test was used to compare OCP levels between the groups. Spearman correlation was used to find the correlation between individual pesticide levels with age and seizure duration. Results. Levels of β, γ, and total HCH were significantly higher among cases as compared to the control group (P≤0.05). Conclusion. There exists a possible association between idiopathic seizures and high serum levels of OCPs, especially HCH.

African trypanosomiasis is a parasitic disease that affects both humans and animals. This study investigated the antitrypanosomal activities of crude and an alkaloidal fraction of Diospyros mespiliformis in Trypanosoma evansi – infected rats. A total of twenty-one (21) albino rats were infected with Trypanosoma evansi and grouped into seven (A-G) of 3 rats each. Group A serve as normal control, groups B and C were given 0.2 ml normal saline/kg BW and 3.5 mg/kg BW diminazene aceturate respectively, groups D and E were treated with 100 and 200 mg/kg BW alkaloidal while groups E and F received crude extract at 200 and 400 mg/kg respectively for twelve days. Results revealed that both crude and an alkaloidal fraction of D. mespiliformis exhibited significant (p<0.05) dose-dependent antitrypanosomal activities. The crude extract exhibited 54.55±3.04 % (200 mg/kg BW) and 66.02±5.03 (200 mg/kg BW) curative effect while the alkaloidal fraction exhibited better antitrypanosomal activities with 68.68±2.34 % and 70.87±2.93 curative effect at 100 and 200 mg/kg respectively. Furthermore, the crude extract prolonged the survival of the animals to 19.02±2.06 (200 mg/kg BW) and 22.90±3.78 (400 mg/kg BW) while the alkaloidal fraction at 100 and 200 mg/kg prolonged the survival of the mice to 23.45±1.24 and 29.34±3.45 days respectively and improved the body weight gain of the animals when compared with the non-treated control (13.24±1.33 days). In conclusion, the leaves of Diospyros mespiliformis could be employed for the treatment of T. evansi infection as an alternative to conventional medicines that are besieged with undesirable properties

Ethanolic Leaf Extract

Cadmium is a well-known environmental pollutant that has been proven to be nephrotoxic and hepatotoxic in the body. In this study, the effect of ethanolic leaf extract of Irvingia gabonensis (O’Rorke) Baill (IG) against cadmium-induced nephrotoxicity and hepatotoxicity in Wistar albino rats was investigated. 30 female wistar rats of weights between 98-153g were grouped into 6 groups of 5 animals each. Group 1 served as the control and was placed on rat feed and water. Groups 2, 3, and 4 were administered 10mg/Kg body weight (mg/kgbw) of cadmium chloride (CdCl2) only,10mg/Kgbw CdCl2 and 200mg/kgbw extract, 10mg/Kgbw CdCl2 and 400mg/kgbw extract, respectively. Groups 5 and 6 were given 200mg/kgbw and 400mg/kgbw of IG extract respectively and the treatments lasted for 28 days. Results obtained revealed significant (p<0.05) increases in the serum levels of all renal and liver function biomarkers in group 2 (CdCl2 only) as compared with the control. There were however significant (p<0.05) decreases in the serum levels of the assayed parameters when groups 3 and 4 were respectively compared with group 2. It can therefore be concluded that ethanolic leaf extract of Irvingia gabonensis (O’Rorke) Baill enhances the integrity of the kidneys and liver of cadmium-induced wistar albino rats.

Endocrine Disrupting chemicals including bisphenols have contaminated the environment significantly and is known to damage spermatogenesis via increase in oxidative stress. The anti-oxidant properties of naturally occurring substances like curcumin have been well established. Objectives: To evaluate the protective effects of curcumin against bisphenol-A induced testicular damage. Study Design: Experimental Study. Setting: Department of Anatomy, University of Health Sciences, Lahore. Period: From March 2015 to December 2015. Material & Methods: Thirty six rats were divided into four groups A, B, C and D of 9 animals each. Group A (control) was given 5ml/kg/day of corn oil orally for 10 days. Group B (Bisphenol-A) was given 100mg/kg/day of Bisphenol-A dissolved in corn oil orally for 10 days. Group C (recovery) was given 100mg/kg/day of BPA dissolved in corn oil orally for 10 days and left untreated for 10 days. Group D (Curcumin + BPA) was given 100mg/kg/day of BPA and 100mg/kg/day of Curcumin, dissolved in corn oil orally for 10 days. Rats of group A, B and D were sacrificed on day 11 and those of group C on day 21. After weighing the euthanized rats, testes were removed, processed and tissue sections were stained with H&E for Johnson scoring and with PAS stain for assessment of basement membrane integrity. Results: Bisphenol-A administration caused a significant decrease in weight of animals, a significantly low Johnson score of seminiferous tubules and high frequency of disrupted basement membranes of the tubules in Group B as compared to control. The weight gain of animals improved in the with-drawl group C while no self-recovery was observed in other parameters. Curcumin co-administration improved the body weight gain of animals, increased the Johnson scoring of tubules significantly and partially restored the basement membrane integrity in group D, comparable to the control group. Conclusion: The results of this study indicate that co-administration of a potent antioxidant curcumin causes a significant antagonism of the histo-toxicity of testis produced by Bisphenol-A in albino rats.
