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.

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.

 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.

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.

This study aimed to investigate the prophylactic effect of turmeric (Curcuma longa) Rhizome Ethanolic extract (CLRE) at 250 mg/kg as antioxidant effects against penconazole induced sub-acute toxicity. Hepatic, renal and testicular pathological changes caused by oxidative damage induced by penconazole in rats were biochemically and histologically evaluated. Male rats were treated with penconazole, via oral route, at doses of 0.5 mg/ kg body weight (b.w.; acute reference dose, ARfD), 25 mg/kg b.w. (no observed adverse effects level, NOAEL) and 100 mg/ kg b.w. (1/20 lethal dose [LD50]) for 28 consecutive days. Penconazole treatments had significant (p < 0.05) and gradual reductions in body and relative testicular weight accompanied by significant elevation in the relative liver and kidney weights. Significant increase serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dhydrogenase(LDH), gamma-glutamyl transferase (GGT), creatinine (Cre), uric acid and blood glucose was observed due to penconazole treatments. However, total protein and testosterone hormone were significantly decreased. Exposure to penconazole caused increase in lipid peroxidation (LPO) and decreased of liver and kidney antioxidant enzymes activity as catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx). Histopathological studies confirmed the ameliorative beneficial effects of turmeric biochemical parameters. On the basis of this study, the use of tumeric rhizomes as a functional food or as a nutraceutical product could be a useful approach to protect individuals who are regularly exposed to penconazole.

The adverse effect of cypermethrin on the liver and kidney of weanling female rats and the protective effect of ethanolic extract of grape pomace were investigated in the present study. Weanling female rats were given cypermethrin oral at a dose of 25 mg kg−1body weight for 28 consecutive days. An additional two Cyp-trated groups received extract at a dose of 100 and 200 mg kg−1body weight, respectively, throughout the experimental duration. Three groups more served as extract and control groups. Administration of Cyp resulted in a significant increase in serum marker enzymes, for example, aminotransferases (AST and ALT), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT), and increases the level of urea nitrogen and creatinine. In contrast, Cyp caused significant decrease in levels of total protein and albumin and caused histopathological alterations in liver and kidneys of female rats. Coadministration of the extract to Cyp-treated female rats restored most of these biochemical parameters to within normal levels especially at high dose of extract. However, extract administration to Cyp-treated rats resulted in overall improvement in liver and kidney damage. This study demonstrated the adverse biohistological effects of Cyp on the liver and kidney of weanling female rats. The grape pomace extract administration prevented the toxic effect of Cyp on the above serum parameters. The present study concludes that grape pomace extract has significant antioxidant and hepatorenal protective activity.

The aqueous extract of the leaves of Leonotis leonurus (L.) R. Br. at the doses of 125, 250 and 500 mg/kg body weight was investigated for toxicity in male rats following administration on daily basis for 21 days. The extract did not significantly (p > .05) alter the levels of haemoglobin, packed cell volume, mean corpuscular volume, red cell distribution width, basophils, total protein, phosphorus, calcium and chloride ions of the animals. Whereas the levels of lymphocytes, eosinophils, monocytes, triacylglycerol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, atherogenic index, albumin as well as alkaline phosphatase and gamma glutamyl transferase activity were decreased by the extract, those of neutrophil, magnesium, total and conjugated bilirubin, alanine and aspartate aminotransferase as well as liver and kidney body weight ratios increased. There was decrease in the mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration and cholesterol only at the 500 mg/kg body weight of the extract, whereas the large unstained cells, sodium ions, white blood cells and uric acid increased only at 250 and 500 mg/kg body weight of the extract, respectively. The urea, creatinine and potassium increased only at 125 mg/kg body weight of the extract while the globulin content was elevated only at 500 mg/kg body weight of the extract. The doses did not produce any definite pattern of effect on the red blood cells and platelets. These alterations by the aqueous extract of L. leonurus leaves on the haematological together with the liver and kidney functional indices suggests parameter and dose-selective effects of the extract and will have consequential effects on the normal functioning of the blood system, kidney and liver of the animals. The extract is also unlikely to predispose the animals to cardiovascular risk when repeatedly consumed on daily basis at the doses investigated for 21 days. Therefore, the aqueous extract of L. leonurus leaves may not be ‘safe’ as oral remedy in male rats.

Background: This study evaluated the effects of 1:1 mixture of aqueous root bark extracts of Anogeissus leiocarpus (DC) Guill & Perr (Combretaceae) and Terminalia avicennioides Guill & Perr (Combretaceae) in male rats. Methods: Male rats were orally administered a 1:1 mixture of both extracts (250, 500 and 1000 mg/kg body weight) for seven days. Liver and kidney function indices, haematological parameters and the levels of malondialdehyde were evaluated in the animals at 7 days post-administration of the mixture of the extracts. Results: Administration of mixture of the extract significantly (p<0.05) increased the activities of liver and kidney alkaline phosphatase and reduced the serum alkaline phosphatase, liver and serum aspartate aminotransferase, alanine aminotransferase and gamma glutamyl transferase activities. The mixture also decreased the levels of serum chloride ions, liver and kidney malondialdehyde. Furthermore mixture significantly (p<0.05) increased the serum total protein concentrations whereas the levels of serum albumin, creatinine, urea, potassium, sodium and bicarbonate ions, red blood cells, white blood cells and their related indices were not significantly (p>0.05) altered. Conclusions: The present study revealed that the mixture caused functional toxicity of the liver and kidney of male rats without any evidence of haematotoxicity. The consumption of the 1:1 mixture of the plant extracts at 250, 500 and 1000 mg/kg body weight has some toxic implications in male rats.

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.

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.

Background: The use of herbal medicines for treating ailments is rampant in recent years, and the toxicity implications of various plant preparations are sparingly reported. We investigated the potential effect of daily administration of aqueous extract of stem-bark of cashew tree on the liver and kidney status of rats. Methods: Rats were divided into 4 groups as follows: control rats received 1 mL of distilled water, G1 received 100 mg/kg, G2 received 200 mg/kg, while G3 received 400 mg/kg body weight of the extract for 28 consecutive days. The tissue homogenate supernatants were analysed for liver enzymes-alanine aminotransferase (ALT), alkaline phosphatase (ALP), aspartate aminotransferase (AST) and gamma glutamyl transferase (GGT) and kidney function indices- urea and creatinine. Results: In comparison to control, total protein increased significantly (P< 0.05) at 400 mg/kg extract, whereas albumin level significantly decreased (P<0.05) in rats treated with extract. .Activities of AST, ALP and GGT increased markedly (P< 0.05) at 400 mg/kg, whereas a significant decrease was observed in bilirubin level when compared with the control. Levels of urea and creatinine in kidney tissue were significantly higher in extract-treated rats compared to control. Conclusion: The findings suggest that the extract dose at 400 mg/kg may cause alterations with toxic implications in the liver and kidney of rats.
