Throughout the history of man, traditional and herbal method of treatment of diseases has been used without considering the dose effect. Therefore, this present study is an attempt on investigating the effect of different doses of Annona squamosa methanolic leaf extract on male wistar Rats especially the delicate organs. The work involves oral administration of different doses (10, 100, 1000, 1600, 2900, 5000 mg/kg body weight) of the extract to groups of rats according to Lorkes method. The animals were monitored for 30 days at every 24 hours interval in order to find the median lethal dose (LD50) of the extract. Internal organ-body weight ratios (OBR) of animals in the test groups were determined and compared with those of the control group. LD50 was found to be greater than 5000mg/kg body weight without any significant decrease (p>0.05) in body weight. Biochemical analysis of Aspartate amino transferase (AST), Alanine amino transferase (ALT), Albumin and globulin of animals administered with extract showed no significant difference compared to the control groups (p>0.05) but concentration of Alkaline Phosphatase (ALP) indicated obvious changes in the treated groups compared to the control groups (p<0.05). Histopathology of the kidney revealed some inflammation at 1000, 1600, and 5000 mg/kg body weight. The implications of using this extract within safe doses in traditional medicine is hereby discussed

Gongronema latifolium is highly medicinal in nature. The fundamental ingredients used for medicinal purposes are stored in the various parts of the plant such as the fruits, seeds, leaves, root and stem. This present study is aimed to evaluate the hepatotoxicity effect of methanolic leaf extract of Gongronema latifolium on albino rats. This study was divided into five groups normal control groups: received commercial rat feed and water, group 2: received 1000 mg/kg b.w. of leaf extract of Gongronema latifolium, group 3: received 500 mg/kg b.w of leaf extract of G. latifolium, group 4; received 250 mg/kg of leaf extract of Gongronema latifolium, and group 5: received 125mg/kg of leaf extract of Gongronema latifolium. The result shows a significant (p<0.05) increase in serum levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total and conjugate bilirubin when compared to the normal control not giving the extract. Administration graded dosage of 1000mg/kg and 500mg/kg body weight significantly (p<0.05) increased the liver damage marker enzymes when compared with groups that received low dosage of 250mg/kg and 125mg/kg body weight and the normal control groups. The histopathological study revealed severe portal inflammation without steatosis and moderate portal inflammation in groups that received 1000mg/kg and 500mg/kg. Therefore, these results suggested that methanol leaf extracts of Gongronema latifolium possess hepatotoxic properties and strict caution must be observed when using the plant extract as a natural remedy of any disease.

Abstract Background Spondias purpurea is a flowering plant of the cashew family commonly found in South Western Nigeria. The plant is used in folk medicine for treatment of gastric disorders and diarrhoea. The purpose of the study was to investigate the haematological and histopathological effects of aqueous and ethanol leaf extract of S. purpurea (red plum) in rats. Methods Female wistar rats weighing (121.5 ± 30.41 g) were administered 500, 1000 and 1500 mg/kg body weight of aqueous and ethanol extracts of S. purpurea leaf (orally) daily for 14 days, while the control group was administered 0.5 ml of normal saline (vehicle). At the end of the study, the rats were euthanized; blood samples were collected for haematological parameters. The liver, kidney and spleen were harvested from the rats for photomicrographic examination. Result The result of the acute toxicity test revealed no death with dose up to 5000 mg/kg body weight. The administration of the extracts showed no significant difference (p > 0.05) in the hematologic parameters of the animals. The liver sections showed congestion, mononuclear infiltration, widened sinusoidal space and congestions with hemosiderin. Similar changes were observed in the kidney showing slight necrosis of renal tubular epithelium, widened Bowman’s space, and collapsed renal tubules and adhesion of the parietal layer of glomerulus to the Bowman’s space. The spleen showed congestion, lymphocyte proliferation at the germinal centre. Conclusions The result of this study showed that the alterations observed in the organs intensified with increase in the doses of the extracts administered. It can be inferred that the prolonged consumption of S. purpurea leaf maybe associated with significant tissue damage of some vital organs.

AbstractIn this study, we attempt to verify the claim that the leaf-extract of Telfairia occidentalis can remedy oxidative damage condition as well as assess its phytochemical content. Fifteen male albino rats weighing 180 g to 240 g were randomly divided into three groups of five rats each. Group A was designated the control group while group B and C were both induced with 40 mg/kg body weight 2,4-dinitrophenyl hydrazine. Group C was subsequently treated with 200 mg/kg body weight of ethanol extract of T. occidentalis leaf for 21 days. At the end of the treatment, the animals were sacrificed, and serum of the samples were subjected to relevant tests. Result shows that the plant leaf contained saponin, tannins, alkaloids, flavonoids and phenols whereas, terpenes, steroids and anthraquinones were not detected. The serum enzymes alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were significantly elevated from 17.43 u/L and 28.40 u/L to 21.60 u/L and 34.27 u/L respectively. These were significantly lowered in the group C to 18.37 u/L and 29.23 u/L respectively for ALT and ALP. Also, a significant lowering of superoxide dismutase (SOD) activity was observed in the treated group (54.33 u/mg) from 79.40 u/mg recorded in the intoxicated group. Similarly, a significant decrease in malondialdehyde was observed in the treated group (25.80 u/mg) relative to the intoxicated group (35.87 u/mg). Moreover, catalase activity in the treated group (7.43 u/mg) was significantly lower compared with the intoxicated group. Our observation confirmed that ethanolic leaf extract of T. occidentalis reversed the oxidative damage condition in albino rats. The result confirms the ethnomedicinal use of the plant in the management of oxidative stress related diseases.

Aim: To investigate whether the aqueous extract of avocado leaves can be used in alternative medicine for the remediation or treatment of lead poisoning in the brain. Study Design: Pure Experiment, using animal models. Place and Duration of Study: Department of Anatomy, College of Medicine and Health Sciences, Abia State University, Uturu, Nigeria; between January 2019 and June 2019. Methodology: Twenty albino Wistar rats including both male and female, and weighing around 155 g were randomly assigned to four groups (designated as A,B,C and D), with each group consisting of five animals. While group A served as the control, group B was administered a daily dose of 500 mg/kg body weight of avocado leaf extract, group C received 150 mg/kg body weight per day of lead acetate, and group D was given 150 mg/kg body weight per day of lead acetate and immediately followed with 500 mg/kg body weight/day of the avocado leaf extract. Treatments were given once daily through the oral route using a syringe with attached micropipette tube for 15 days, while the animals had access to water and chow ad libitum. The rats were euthanized on the 16th day by cervical dislocation and the cranial cavity was carefully exposed in order to dissect the brain and to obtain tissue samples from the cerebellum, which were then prepared for microscopic examination using routine histological techniques, with hematoxylin and eosin (H&E) stains. Results: The findings showed the extract to be ameliorative by reducing histomorphological distortions of lead acetate toxicity in the brain, and thus caused moderate regeneration of the cerebellar tissue. Conclusion: The outcome of this research therefore indicates that the avocado leaf extract has medicinal potentials and could serve as an herbal remedy in the alternative treatment of lead poisoning.

Toxicological evaluation of aqueous leaf extract of Spondias mombin using albino rat was carried out. Twenty-five albino rats were grouped into five groups of five rats each. Group 1 served as the control, while groups 2-5 served as the test groups. The test groups were placed on different doses of the studied leaf extract after the lethal dose was determined. The studied extractconsists mainly of flavonoids, saponins, alkaloid, tannins and cyanogenic glycosides, which have considerable therapeutic values, and reduced body weight considerably in test rats against the control. Levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP)in test rats reduced significantly (p<0.05) when compared to the control. However, the observed histopathological changes associated with the kidney and liver of test rats against those of the control may suggest that the toxicity of the extract could be dose dependent. This study has shown the toxicological evaluation of aqueous leaf extract of S. mombin using albino rat.

This study was designed to evaluate the Lithotriptic potentials of Phyllantus fraternus methanol leaf extract on ethylene glycol-induced kidney calculi in albino rats. Ethylene glycol (1% v/v) was administered in their drinking water for a period of 28 days. The Treatment was done with the extract at 200 mg/kg, 400 mg/kg and 600 mg/kg body weights. Cystone® at 500 mg/kg body weight was also given for a period of 21 days to the standard control group. The serum parameters such as calcium, phosphates, magnesium and albumin were measured and evaluated. The results for the Lithotriptic activity, where the kidney homogenates were analyzed are described as thus, the phosphate concentrations when compared were significant (p<0.05) between the groups’ 600 mg/kg body weight (9.61 ± 1.17) and the normal control (5.67 ± 0.70). Significant differences (p<0.05) for phosphates were also observed between 600 mg/kg (9.61 ± 1.17) and 200 mg/kg body weights (12.06 ± 0.51); 400 mg/kg (7.64 ± 0.44) and 200 mg/kg body weights (12.06 ± 0.51) and the 200 mg/kg and standard control groups Cystone® (7.96 ± 0.56) respectively. Significant differences (p<0.05) were also observed for phosphates concentration, when the normal control (5.67 ± 0.70) was compared to the 400 mg/kg body weight (7.64 ± 0.44) and the standard control group Cystone® (7.96 ± 0.56). From this study, it can be deduced that, the presented data indicated that, the administration of Phyllanthus fraternus methanol leaf extract to rats with ethylene glycol-induced kidney calculi, reduced and prevented the growth of kidney calculi, supporting the folklore claim regarding its Lithotriptic activity.

Background and Objectives: Nephrotoxicity is one of the limiting factors for using doxorubicin as an anticancer chemotherapeutic. Reactive oxygen species and cytokines have been implicated in the nephrotoxicity induced by doxorubicin. The main objective of the present study is to identify and compare the histomorphological features in kidneys of albino rats and gross morphological features such as weight of rats and weight of the kidneys due to administration of doxorubicin. Materials and Methods: In the study, albino rats were taken as the animal model. Sixty animals were taken as the sample size. They were divided into two equal groups: experimental (n=30) and control (n=30). Rats of experimental group were treated with anticancer drug doxorubicin at a single intraperitoneal dose of 10 mg/kg body weight while the Control group of rats received a similar volume of 0.9% normal saline. The ethical clearance was taken prior to the research from IERB committee BPKIHS Dharan.  Results: Our results showed that there was high effect of drug in experimental groups of rats. It was seen that there was significant decrease in the body weight and weight of kidneys. The final body weight and kidney weight between experimental and control group showed the significant difference. Similarly there were no significant differences in the normal architecture between the male and female rats. The normal renal histological features were seen on the kidneys in the control group whereas the rats intervened with the drug had some disrupted histological features which reveal the toxicity of the drugs in the kidneys. Conclusion: The study showed toxicity of the drug in the kidneys of experimental groups of rats irrespective of gender and suggest that doxorubicin causes significant loss of the body weight and weight of kidneys and causes the disruption in the normal histological features.

Abstract Background:Polyethylene glycol losenatide (PEX-168) is a new antidiabetic drug; as such, there are not yet any reports on its weight loss effect. Therefore, this trial was designed to investigate the effect of PEX-168 on simple obese mice.Methods:Thirty healthy male C57BL/6 mice were randomly selected and divided into a control group (NC) and an obesity model group. The high-fat diet-induced simple obesity mice were divided into a model control group (HF) and three intervention groups. The intervention groups were injected with different doses of PEX-168 intraperitoneally once a week for 12 weeks (low (LD), medium (MD) and high (HD)). Fasting blood glucose (FBG), body weight and food intake were measured from 1 to 12 weeks after PEX-168 injection. The serum insulin (INS), C-reactive protein (CRP), chemerin and omentin levels were measured after 12 weeks.Results:Compared with the HF group, the low dose of PEX-168 reduced the body weight of the mice in a short period of time (8 weeks), and the mice in the LDand HD groups showed a significant decrease in body weight (P < 0.05). The low dose of PEX-168 could effectively improve the blood glucose and insulin resistance index (Homa-IR) of the mice (FBG P < 0.05 INS, Homa-IR P < 0.001), but there was no significant difference between different doses (P > 0.05). CRP levels in the HD and LD groups were significantly improved (P < 0.05). The levels of serum chemerin and omentin in the intervention groups were also significantly improved (P < 0.01), but there was no significant difference between the different doses (P > 0.05).Conclusion:PEX-168 significantly reduced the body weight of simple obese mice and prevented the development of diabetes. PEX-168 may regulate the expression of chemerin and omentin mainly through its hypoglycaemic effect, and the weight-reducing effect of PEX-168 is unlikely to be the reason for the changes in both.

Introduction: Citrus aurantifolia (Christm) is a plant used for the treatment of various ailments including malaria. This study aimed to evaluate the in vivo antiplasmodial efficacy of methanol leaf extract of C. aurantifolia in Swiss albino mice. Methods: The median lethal dose (LD50) was determined by intraperitoneal administration of different doses of the extract (100–4000 mg/kg) to 6 groups of 3 mice each and the animals were observed for 24 hours for physical signs of toxicity. To evaluate the antiplasmodial activity of the extract, three models were used: suppressive, curative and repository. Doses of the extract used were 320, 640 and 960 mg/kg/d in mice, with Chloroquine (5 mg/kg/d) as standard drug. Pyrimethamine (1.2 mg/kg/d) was used as the standard drug for the repository test and distilled water (10 mL/kg/d) as control in all models. Results: In all models, the low dose (320 mg/kg) of the extract produced the highest chemosuppressive effects in all models (P < 0.001). Mice treated with extract lived longer than those in the control group (P < 0.001). Phytochemical screening revealed the presence of alkaloids, flavonoids, saponins, tannins and cardiac glycosides and the LD50 of 3280 mg/kg ± 0.01 shows that the extract has low toxicity. Conclusion: The result of this study shows that C. aurantifolia has antiplasmodial properties which support its use in ethnomedicine in the treatment of malaria.
