Aqueous extract of Bambusa vulgaris L. leaves at 250 and 500 mg/kg body weight was investigated for toxic effects in pregnant rabbits. Apparently healthy, female rabbits (Dutch) weighing between 1.62 and 1.70 kg as previously used in our abortifacient study were paired overnight with male rabbits in ratio 2:1 and those that became pregnant were completely randomized into three groups (A-C). Group A (the control), received orally 1.85 mL/kg body weight (3 mL) of distilled water thrice daily on days 1-9 of pregnancy while groups B and C were treated orally with the same volume corresponding to 250 and 500 mg/kg body weight of the extract. Clinical signs of toxicity were not observed in all the animals during the study. The extract did not significantly alter (p > .05) the serum follicle stimulating hormone and total protein content of the pregnant rabbits throughout the exposure period whereas, the concentrations of luteinizing hormone, progesterone, albumin, globulin, urea and calcium decreased in the serum of the rabbits. At 250 mg/kg body weight, the extract increased kidney alkaline phosphatase (ALP) activity whereas at 500 mg/kg body weight of the extract, the ALP level was similar to the control group. Liver ALP at all doses, as well as the activity of gamma glutamyl transferase (GGT) at 500 mg/kg body weight was reduced. This reduction was accompanied by an increase in serum ALP and GGT at these doses. At 250 mg/kg, the extract increased kidney GGT. Conversely, at 500 mg/ kg, kidney GGT activity decreased. Liver and serum GGT were not altered by the 250 mg/kg. The extract also increased the serum levels of creatinine, uric acid, sodium, potassium and bicarbonate ions as well as total and conjugated bilirubin. In the hepatocytes of extract-treated animals, there was no evidence of necrosis, inflammation, fibrosis and degenerative changes in the central vein and radiating hepatic cords, while the glomerulus and the tubules of the nephrons also remained intact. The alterations in biochemical parameters by the aqueous extract of B. vulgaris leaves suggests adverse effect on the synthetic, secretory, reabsorptive and excretory functions of liver and kidney of the animals. Therefore, the absence of histopathological lesions in the hepatocytes and nephrons implies that histopathological changes are not a sensitive assay for the assessment of tissue damage by the extract.

The present study investigated the effect of leaf extract of Gangronema latifolium (G. latifolium) on acetaminophen (APAP) - induced liver injury in Wistar albino rats. In this study, sixty (60) male Wistar albino rats were divided into five (5) groups of twelve (12) rats each. Animals in group 1 served as control group and received a placebo of 0.9% saline solution. Group 2 served as APAP control group, administered with 800 mg/kg body weight of APAP only. Groups 3, 4 and 5 served as the experimental groups and received oral dosage of 800 mg/kg body weight of APAP plus 150 mg/kg, 200 mg/kg and 250 mg/kg body weight of G. latifolium respectively. The results showed that the enzymatic activities of alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) in the serum were decreased significantly (p ≤ 0.05) in the experimental groups dosed with 150 mg/kg, 200mg/kg and 250 mg/kg of G. latifolium respectively. For 150 mg/kg G. latifolium treated group, ALT decreased from 23.3 ± 7.31 to 9.00 ± 1.52 IU/L, while AST and ALP decreased from 17.6 ± 2.66 to 15.00 ± 1.00 IU/L and 92.8 ± 2.34 to 83.8 ± 7.94 IU/L respectively. In conclusion, the results showed that aqueous extract of G. latifolium has a protective effect on rat liver induced with APAP injury.

 Objective: The current study was designed to estimate the potential protective role of the aqueous extract of rosemary (AER) (Rosmarinus officinalis) against trichloroacetic acid (TCA)-created hepatotoxicity in male albino rats.Methods: Forty male albino rats were separated into four groups of ten: Group I served as control; Group II was given AER (200 mg/kg/day) by gavage; Group III received TCA at the dose 50 mg/kg/day, and Group V was treated with AER (200 mg/kg/day) and received TCA (50 mg/kg/day). The experiment was carried out for 2 months.Results: The toxicity of TCA for rats was revealed by an elevation in liver marker enzymes activities (gamma-glutamyl transferase [GGT], alkaline phosphatase [ALP], aspartate transaminase [AST], alanine aminotransferase [ALT]) and conjugated bilirubin (CB) level, and a decrease in albumin and total protein (TP) levels. The TCA administration also caused a significant increase in the activities of catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD), and also malondialdehyde (MDA) level in liver tissues. These biochemical effects were accompanied by histological indicators of liver damage. Treatment with ARE recovered the liver damage instigated by TCA, as showed by perfection of liver enzyme markers (GGT, ALT, AST, ALP), CB, TP and albumin; as well as antioxidant parameters (CAT, SOD, GPx) and lipid peroxidation (MDA) and amelioration of histopathology changes in the liver tissues.Conclusion: It could be concluded that AER supplementation for 2 months in TCA-induced toxicity in rats benefited hepatic antioxidant status and improved liver injury and damage in male albino rats exposed to TCA.

Abstract The main objective of current study was to investigate the chemopreventive and chemotherapeutic activity of Artemisia vulgaris extract on diethylnitrosoamine induced hepatocarcinogenesis in Balb C mice. Diethylnitrosoamine (DEN: 0.9%) was prepared to induce hepatocarcinoma in Balb C mice. The extract Artemisia vulgaris (AV) was prepared by maceration technique. Mice were classified into four groups as follows: Group 1 a control group (N=7) received saline solution (3.5 μl/mg), group 2 (N=14) received diethylnitrosoamine (3.5 μl/mg) intraperitoneally once in a week for eight consecutive weeks, group 3 (N=7) received only plant extract (AV: 150 mg/kg (Body weight) once in a week, while group 4 (N=7) was given in combination of diethylnitrosoamine (3.5 μl/mg) and plant extract (AV: 150 mg/kg (body weight). After eight weeks of DEN administration, mice of group 2 were divided into two subgroups containing seven mice each; subgroup 1 was sacrificed while subgroup 2 was treated with plant extract only (150 mg/kg (body weight)) once in a week for eight consecutive weeks. The DEN injected mice significant decline in levels of albumin with concomitant significant elevations such as aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, alpha feto protein, gamma glutamyl transferase, 5 nucleotidase, glucose-6-phosphate dehydrogenase and bilirubin. The administration of A. vulgaris significantly decreased the DEN induced hepatotoxicity. Present study revealed the potential anti-cancerous nature of Artemisia vulgaris, both in case of chemopreventive and post-treatment of A. vulgaris. Further studies are needed to explore the mechanism of prevention and therapy.

Pregnancy ketosis has been recognized as one of the common metabolic disease affecting goat’s meat and milk production. For the present study, sixteen (n=16) individuals of pregnant does at day 80 of pregnancy had been used. A total of 8 does were categorized as control group (healthy pregnant goats), were fed on Napier grass and goat concentrate with water ad libitum, and another 8 does were considered as treatment group which categorized as ketosis based on the clinical signs and presence of ketone body in urine. Blood sample were collected from all goats for biochemical profiles analysis which were glucose, Beta-hydroxybutyrate (BHBA), free fatty acid (FFA), calcium, electrolytes (sodium, potassium, chloride), liver enzyme and hormonal levels (cortisol and insulin). Three does from each group were slaughtered and liver samples were collected for fatty acid profiles study. In this study, the BHBA, FFA, calcium, amino aspartate transferase (AST), gamma glutamyl transferase (GGT) and cortisol hormone were significantly higher in pregnancy ketosis goats as compared to control group. Meanwhile, the concentration of glucose, sodium, potassium, chloride and insulin hormones were lower in pregnancy ketosis goats as compared to control. Furthermore, the fatty acid composition in blood plasma of pregnant goat with ketosis showed higher level of palmitic, stearic and oleic acid, while in liver, palmitic, oleic and linoleic acid was found higher.

Background: Garcinia kola seed is consumed indiscriminately in Nigeria without recourse to its potential toxicity. Therefore, this study was aimed at assessing the toxicity of the aqueous extract of G. kola seeds on selected tissues of male rats. Methods: Thirty male rats (215.00 ± 18.58 g) were assigned into four groups: A, B, C and D which received 0.5 ml of distilled water, 25, 50 and 100 mg/kg body weight of the extract respectively, once daily for 7 days. Biochemical indices of organ damage and toxicity were determined using standard methods. Results: The extract significantly (P<0.05) increased the testes-body weight ratio, activities of testicular alkaline phosphatase (ALP), heart, testes and serum gamma glutamyl transferase (GGT) activity, serum concentrations of uric acid, K+, creatinine and PO43-. The liver-body weight ratio, activities of kidney and serum ALP, liver, heart and serum alanine and aspartate aminotransferases (ALT and AST), serum and testicular acid phosphatase (ACP), concentrations of serum albumin, globulin, urea, Na+ , HCO3-, conjugated and total bilirubin were reduced. The heart- and kidney-body weight ratios and liver ALP were not significantly (P>0.05) altered. Conclusion: The treatment related alterations in the present study indicates that the aqueous extract of G. kola seeds at the doses of 25, 50 and 100 mg/kg body weight caused functional toxicity to the organs of the animals and thus not safe as an oral remedy.

BackgroundNeonatal sepsis is a leading cause of neonatal death during the first-week postfoaling. Despite recent advancements in the diagnosis and treatment of sepsis in the newborn foal, the non-specific clinical signs and subtle nature of this disease may result in delayed diagnosis until severe progression of the disease; thus, early detection of sepsis remains critical for a favourable outcome. This study aimed to identify early blood markers as predictive of sepsis on foals.MethodsThirty-five foals were allocated into three groups: healthy control foals (n=7) and foals born from mares with placentitis: septic foals (n=9) and non-septic foals (n=19). Blood samples were obtained immediately after foaling and at 12, 24 and 48 hours. All samples were assessed for glucose, lactate, triglycerides, total cholesterol, urea, creatinine, total solids, fibrinogen, gamma-glutamyl transferase (GGT), serum amyloid A (SAA) and alpha-fetoprotein (AFP) concentrations.ResultsAt foaling, glucose and GGT concentrations were lower in septic foals (P<0.001). Of interest, SAA, AFP, creatinine and total cholesterol were higher in septic foals at parturition (P<0.05). At 12 hours, lactate, triglycerides and total cholesterol concentrations were higher in septic foals. When evaluated at 24 and 48 hours, higher concentrations of SAA and AFP were found in placentitis foals than in the control group.ConclusionsTotal cholesterol and lactate appear to be suitable markers for sepsis during the first 24 hours postpartum. Septic foals displayed altered energy metabolisms as determined by increased triglycerides and cholesterol concentrations, hypoglycaemia at birth and reduced activity of the GGT and increased lactate and urea concentrations. Sepsis was associated with high concentrations of SAA and AFP.

The mode of cellular toxicity of aqueous extract of Fadogia agrestis stem in male rats was investigated. Rats were grouped into four: A, B, C and D where A (the control) received orally 1 mL of distilled water; B, C and D (test groups) received orally 18, 50 and 100 mg/kg body weight of the extract, respectively, for 28 days. Infrared spectroscopy indicated the presence of hydroxyl (OH) and primary amine (CONH). Clinical toxicity symptoms such as respiratory distress, epistasis, salivation, hypo- and hyperactivity were not observed at any period of the experiment. No mortality was also recorded. Extract administration significantly reduced (p < .05) the activities of alkaline phosphatase, lactate dehydrogenase and gamma glutamyl transferase in the liver and kidney with corresponding increases in the serum. Serum malondialdehyde also increased significantly in all the extract-treated groups. The liver and kidney body weight ratios of the extract-treated animals compared well (P > .05) with their controls throughout the experimental period. The extract did not cause any swelling, atrophy or hypertrophy of the organs. The other evidence in this study suggests disruption of the ordered lipid bilayer of the plasma membranes of the hepatocytes and nephrons. This might have resulted from peroxidation of the polyunsaturated fatty acids on the membranes of the hepatocytes and nephrons made possible by the functional groups or the product of metabolism of the extract. This may be responsible for the compromise of the integrity of the plasma membranes of the hepatocytes and nephrons.

Abstract Background The cytotoxic properties of nanoparticles have attracted a great deal of attention in the field of nanoscience and nanotechnology due to their small size and ability to penetrate cellular membranes. Methods The silver nanoparticles were synthesized using Elaeodendron croceum stem bark and characterized. The oral acute toxicity studies were carried out by administration of 500, 1000, 2000 mg/kg body weight to Wister rats in respective groups. An in vitro cytotoxicity assay was evaluated in MDA-MB-231 breast cancer cells using the WST-1 Cell Proliferation assay. The percentage of cell viability after treatment with aqueous extracts of Elaeodendron croceum (ECE) and Elaeodendron croceum silver nanoparticles (ECAgNPs) was compared with that of paclitaxel. Results The in vivo studies revealed that the LD50 was higher than 2000 mg/kg and there was no significant difference (p>0.05) between the treatment groups compared with the control group for mean organ-to-body weight ratio except in the liver and in all hematological parameters except WBC and hematocrit. Similarly, there was no significant difference (p>0.05) for serum electrolytes (Na+, Mg2+ K+, Cl−, and Ca2+), total protein, urea, ɣ-glutamyl transferase (GGT), Aspartate aminotransferase (AST), Alkaline phosphatase (ALP), Alanine aminotransferase (ALT), albumin, total and conjugated bilirubin between the treatment and the control group. However, there were changes in creatinine, urea, and cholesterol. In the in vitro assays, ECE and ECAgNPs showed IC50 values of 70.87±2.99 and 138.8±3.98 µg/mL respectively against MDA-MB-231 cells compared to paclitaxel, which showed an IC50 value of 80 ng/mL. Conclusion The results showed that the LD50 of the ECE and ECAgNPs in Wister rats was determined to be greater than 2000 mg/kg body weight. The aqueous extract also showed more cytotoxic than the ECAgNPs suggesting that the toxic compounds in aqueous extract were involved in the capping of the AgNPs.

Cysteine-stabilised peptide fraction of the aqueous extract of Morinda lucida leaf has been reported to exert diverse biological activities, but its effects on the liver have not been evaluated. This study was carried out to evaluate the effects of cysteine-stabilised peptide fraction (CSPF) of aqueous extract of Morinda lucida leaf on selected liver function indices in mice. Sixty mice were randomly divided into six groups of ten mice each. Mice in group A (control) were orally administered 5% DMSO while mice in groups B, C, D, E and F were orally administered 31.25, 62.5, 125, 250 and 500 mg/kg body weight of CSPF respectively. Half of the mice in the groups received the respective doses of CSPF for 7 days while the other half received them for 28 days, after which selected liver function indices in the serum and liver of the mice were determined. The results revealed that plasma alkaline phosphatase, gamma glutamyl transferase and glutamate dehydrogenase activities and plasma albumin, globulin, total bilirubin and conjugated bilirubin concentrations were not significantly (P>0.05) altered after 7 and 28 days of CSPF administration at all doses compared to controls. However, liver alanine aminotransferase (ALT) activity was significantly reduced (p<0.05) at doses of CSPF higher than 125 mg/kg body weight, with no corresponding alteration in serum ALT activity after 28 days of administration compared to controls. Thus, prolonged administration of high doses of CSPF may adversely affect the glucose-alanine cycle in the liver which is very important for glucose homeostasis during fasting.
