Ethnopharmacological relevance: The dry leaf of Alchornea cordifolia (AC) is used, in traditional medicine in the S Nigeria, for the preparation of blood tonic, remedies for urinary, respiratory, liver and gas intestinal disorders. Aim of the study: This study investigated the protective property of AC leaf against liver damage in animals with a view to exploring its use for the treatment of hepatotoxicity in humans. Material and methods:  Ethanol extract of A. cordifolia was used to study the hepatoprotective activity in acetaminophen-induced Albino rats (150-200g). Animals in Group 1 served as vehicle control, Group 2 served as hepatotoxin (Acetaminophen 2g/kg treated) group, Groups 3 and 4 served as positive control (Vitamin E and Curcumin 100 mg/kg bw respectively) groups, and Groups 5-8 served as (200-500mg/kg bw) AC leaf extract treated groups while Group 9 served as normal group (AC extract only 300 mg/kg bw). Results: The hepatotoxic group showed hepatocytic necrosis, cellular infiltration and inflammation in the liver. The treatment group restored the liver cells to their normal lobular architecture in a dose dependent manner. The protection offered by the plant extract compared well with the standard antioxidant agents (Curcumin and Vitamin E). Tannins, flavonoids, alkaloids and saponins were detected in the phytochemical screening. Conclusion: Our findings suggest Alchornea cordifolia ethanol leaf extract as promising herpatoprotective herb and give credence to the folkloric use of this plant for the treatment of liver problems.DOI: http://dx.doi.org/10.3126/ijasbt.v2i2.10473Int J Appl Sci Biotechnol, Vol. 2(2): 217-221

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.

Achillea Fragrantissima

Objective: Achillea fragrantissima L. (Asteraceae) is a traditionally used medicinal herb in the rural communities of Jordan. Methods: The present study evaluated the efficacy of the ethanol extract of this species on angiogenesis in both, ex vivo using rat aortic ring assay and in vivo using rat excision wound model. Results: In concentrations of 50 and 100 µg/ml, the ethanol extract showed angiogenic stimulatory effect and significantly increased length of capillary protrusions around aorta rings of about 60% in comparison to those of untreated aorta rings. In MCF-7 cells, the ethanol extract of A. fragrantissima stimulates the production of VEGF in a dose-dependent manner. 1% and 5% of ethanol extract of A. fragrantissima containing vaseline based ointment was applied on rat excision wounds for six days and was found to be effective in wound healing and maturation of the scar. Both preparations resulted in better wound healing when compared to the untreated control group and vaseline-treated group. This effect was comparable to that induced by MEBO, the positive control. Conclusion: The results indicate that A. fragrantissima has a pro-angiogenic effect, which may act through the VEGF signaling pathway.

Objective: To isolate and evaluate the hepatoprotective activity of the crude ethanolic leaf extract of Averrhoa bilimbi Methods: The leaves of Averrhoa bilimbi were extracted by cold maceration using ethanol as a solvent, and the solvent fractions were obtained with petroleum ether and ethyl acetate. Preliminary phytochemical tests were performed for the presence or absence of secondary metabolites. Plant chemical constituents were isolated using column chromatography and characterized by IR,1HNMR,13CNMR and mass spectroscopic values. Albino rats were treated with the vehicles (distilled water or 2% Tween 80), three different doses (100, 200 and 400 mg/kg) of the crude ethanol extract and the standard drug (silymarin 100 mg/kg), and the hepatotoxicant paracetamol. Then, the levels of biomarkers of liver injury – such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) – and liver function such as bilirubin were measured along with histopathological examination. Results: Preliminary phytochemical studies shown the presence of n-docosanoic acid and beta sitosterol from petroleum extract and from ethyl acetate a flavonoid apigenin.The ethanol extract suppressed the plasma levels of AST, ALT and ALP (P=0.05) in the aforementioned doses. Maximum hepatoprotective activity was observed at the dose of 400 mg/kg body weight. Conclusion: Averrhoa bilimbi is endowed with hepatoprotective activity, probably with the presence its chemical constituents like sterols,flavonoids and terpenoids.

Background: Traditionally, the bark of Pavetta Indica Linn., in decoction or pulverized, is administered, especially to children, to correct visceral obstructions. The decocted leaves are used externally to alleviate the pains caused by hemorrhoids. The root, pulverized and mixed with the ginger and rice-water, is given in dropsy. A local fomentation with the leaves is useful in relieving the pain of piles. Paracetamol (PCM) toxicity generates free radicals and raised serum enzyme levels-SGPT, SGOT, Alkaline Phosphatase and S. Albumin. It causes necrosis, congested vessels, multifocal area of fatty changes nuclear disintegration, sinusoidal dilation, kuffer cell hyperplasia. The reverse is considered as the index of hepatoprotective activity. The present study is being taken up to screen hepatoprotective action of P. Indica Linn.Methods: The acute liver damage in albino rats was induced by per oral administration of a single dose of 2000mg/kg b.w. PCM suspension in 0.5% Carboxy methyl cellulose (CMC) and chronic liver damage by giving the same dose of PCM on the 7th day. The hepatoprotective activity was monitored biochemically by estimating S. transaminase, S. bilirubin and S. Protein on the 8th day of experiment.Results: Ethanol extract of P. Indica inhibited PCM induced liver toxicity in albino rats at 100mg/kg and 200mg/kg b.w as assessed by the biochemical values.Conclusions: Ethanol extract of “P. Indica” exhibited significant hepatoprotective activity.

<p>The aim of this study was to evaluate diuretic activity of aqueous methanolic extract of <em>Euphorbia granulate</em> in rats. Albino rats were divided into five groups. Group I served as reference, Group II as standard and Group III, IV and V served as test. The three doses of extract (30, 50 and 100 mg/kg) were given to rats (i.p) in acute diuretic model. Furosemide (10 mg/kg i.p) was used as standard drug. The extract induced diuretic effects and induced electrolytes excretion in a dose-dependent manner when compared with control. The extract (100 and 50 mg/kg) significantly (p&lt;0.01) increased the volume of urine in comparison to control group. Similarly, the excretion of potassium and sodium were also significantly (p&lt;0.05) increased following extract administration. However, there was no significant change in the pH of urine samples of the extract-treated group compared with control. The result of this study thus offers support to the traditional folker use of this plant as a diuretic agent.</p><p> </p>

Leaves of I. batatas have been implicated in both the hematopoietic process and in the management of hyperlipidemia in man. The current study evaluated the hematopoietic potentials and the lipid profile stabilizing potential of ethanol leaf extract of I. batatas in albino rats. The study was carried out at the Department of Biochemistry and Molecular Biology of the Nasarawa State University, Keffi, between March 2019 and October 2019. The determination of the phytochemical composition of the leaves was carried out. Sixteen albino rats weighing between 100-150g were randomly distributed into 4 groups of 4 rats each. Animals in group 1 served as the control while animals in groups 2, 3, and 4 served as the test groups and were administered 200, 300 and 400g/kg body weight respectively of ethanol leaf extract of I batata for fourteen days following standard procedures. The extract contained terpenoids in high amount, flavonoids and alkaloids in moderate amounts, while glycosides, phenolic, and steroids were present in low amounts. WBC counts increased significantly across the test groups compared to the control. PLT decreased significantly (P = 0.05) in all the test groups when compared to the control group. MCV increased significantly (P = 0.05) in all the test groups when compared to the control group. MCH increased significantly (P = 0.05) in group 2 but decreased significantly in groups 3 and 4 when compared to the control group. The lipid profile parameters; triglycerides (TAG), total cholesterol (TC), low density lipoprotein (LDL-C) showed no significant changes but HDL-C decreased significantly in group 4 compared to the control. The outcome of this study revealed that the ethanol leaves extract of I. batatas may possess a hematopoietic effect but may not be effective in the management of hyperlipidemia.

Anthocleista vogelii was investigated for the acclaimed fertility enhancing properties especially in females. The phyto-chemistry of the ethanolic leave extract of Anthocleista vogelii was determined prior to it being administered orally for 14 days to Wister albino rats. Micronor (norethisterone) or N-acetylcysteine (NAC) was given orally to induce temporary infertility in the female rats for seven (7) days prior to other treatment. The Blood samples from experimental animal groups were collected through cardiac puncture when the rats were sacrificed after the completion of fourteen (14) days extract administration. The vitamin E analysis was performed using HPLC. The hematological parameters were performed using the Sysmex® Automated Hematology Analyzer KX-21N. Biochemical evaluation of glutamic pyruvate transaminase ALT, alkaline phosphatase ALP, glutamic oxaloacetate transaminase AST, total cholesterol and total triacylglycerol was done using randox biochemical kits. The extract was found to possess Anthraquinones, Terpenoids, Flavonoids, Saponins, Alkaloids, Phenols and Phytosterols. The hematological parameters showed a significant increase (P<0.05) in absolute middle cells (basophils, eosinophils and monocytes) count. It also showed a significant reduction in the ALP, ASP, AST, TAG and cholesterol level (p<0.05). The obtained results showed a significant increase of vitamin E concentration in the female rats in the control group compared to extract treated group. The result also suggest that Anthocleista vogelii may have a role in creating the environment required for enhancing pregnancy with the Vitamin E concentration production that support the claims on the traditional use of Anthocliesta vogelii to enhance fertility in female.

Background: Liver damage can be occurred due to prolonged use of higher doses of some drugs, exposure to some chemicals or infectious agents. But liver protective drugs are not available in modern medicine. Some hepatoprotective herbal medicines are often used in the treatment of liver damage. Objective: This experimental study was carried out to observe the hepatoprotective effect of Oyster mushroom (Pleurotus florida) against paracetamol induced liver damage in Wistar albino rats. Method: This experimental study was carried out in the Department of Physiology, Sir Salimullah Medical College (SSMC), Dhaka from 1st July 2009 to 30th June 2010. A total number of 34 Wistar albino rats, age ranged from 90 to 120 days, weighing between 150 to 210 grams were selected for the study. After acclimatization for 14 days, they were divided into two groups, control group (Group A) and experimental group (Group B- mushroom pretreated and paracetamol treated group). Control group again subdivided into group A1 (baseline control) and group A2 (paracetamol treated control group). All groups of animals received basal diet for 30 consecutive days. Group A1 consisted of 10 rats, received propylene glycol (2 ml/kg bw, orally) only on 30th day. Group A2 consisted of 14 rats, received single dose of paracetamol suspension (750 mg/ kg bw, orally) only on 30th day. Group B consisted of 10 rats, received mushroom extract (200 mg/ kg bw, orally) for 30 consecutive days and paracetamol suspension (750 mg/ kg bw, orally) only on 30th day. All the animals were sacrificed on 31st day. Then blood and liver samples were collected. Initial body weight, final body weight and liver weight were measured. Then measurement of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in serum and assessment of malondialdehyde (MDA) concentration in liver tissue homogenate were done by using standard laboratory kits. The statistical analysis was done by one way ANOVA and Bonferroni test as applicable. Result: The mean serum AST, ALT levels and in the liver tissue MDA concentration were significantly (p<0.001) higher in paracetamol treated group in comparison to those of baseline control group. Again, the mean serum AST (p<0.05), ALT (p<0.05) levels and in the liver tissue homogenate MDA concentration (p<0.001) were significantly lower in mushroom pretreated and paracetamol treated group (experimental group) when compared to those of only paracetamol treated group (control). Conclusion: This study reveals that Oyster mushroom (Pleurotus florida) which is excellently edible and nutritious, may have some hepatoprotective role.

Backgroud: Liver is an important metabolic organ. It has wide range of functions including detoxification, storage of glycogen, vitamins A, D and B12, production of several coagulation factors, growth factors such as insulin-like growth factor-1 (IGF-1), angiotensinogen, and biochemicals necessary for digestion (bile). Its damage occurs due to its multidimensional functions, various xenobiotics and oxidative stress leading to distortion of all of its functions. Oyster mushroom which is excellently edible and nutritious has got free radical scavenging activity, and so may be considered as a hepatoprotective agent. Objective: To observe the hepatoprotective effect of Oyster mushroom (Pleurotus florida) against paracetamol induced liver damage in Wistar albino rats. Materials and Methods: This experimental study was carried out in the Department of Physiology, Sir Salimullah Medical College (SSMC), Dhaka from 1st July 2009 to 30th June 2010. Thirty four Wistar albino rats, aged 90 to 120 days, weighing between 150 to 210 grams were used for the study. After acclimatization for 14 days, they were divided into two groups –– control group (Group A) and experimental group (Group B, mushroom-pretreated and paracetamol-treated group). Control group was again subdivided into Group A1 (baseline control group) and Group A2 (paracetamol-treated control group). Animals of all groups received basal diet for 30 consecutive days. In addition, Group A1 rats received propylene glycol (2 mL/kg body weight orally) only on 30th day, Group A2 rats received single dose of paracetamol suspension (750 mg/kg body weight orally) only on 30th day and Group B rats received mushroom extract (200 mg/kg body weight orally) for 30 consecutive days and paracetamol suspension (750 mg/kg body weight orally) only on 30th day. All the animals were sacrificed on 31st day. Then liver specimens were collected. Histology of liver was done by using standard laboratory procedure. Statistical analysis was done by one way ANOVA test by using SPSS version 15.0. Result: In this study, histological examination of liver reveals abnormal histological findings in 100% of rats in paracetamol-treated group (Group A2), almost normal structure in 80% of rats and mild histological changes in 20% rats in mushroom-pretreated and paracetamol-treated group (Group B). Conclusion: The present study reveals the hepatoprotective effect of Oyster mushroom (Pleurotus florida) against paracetamol induced liver damage in Wistar albino rats.

The present study was designed to assess the possible hepatoprotective activity of the leaf ethanolic extract of coded plant (Code No. 222**) against carbon tetrachloride (CCl4)-induced hepatic injury in Wistar albino rats. The animals were divided into different groups and treated with 222 leaf ethanolic extract at different concentrations for five days. Silymarin, the known hepatoprotective standard compound (100 mg/kg) was administered for five days. Hepatotoxicity was induced by the subcutaneous administration of a single dose of CCl4: Olive oil (2 mL/kg) on days 2 and 3. The administration of CCl4 resulted in marked increase in serum hepatic enzymes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST) and serum bilirubin levels. CCl4 intoxication also resulted in a significant (P=0.05) increase in malondialdehyde (MDA), which is a common marker of lipid peroxidation. The other biochemical parameters such as cholesterol, triglycerides, creatinine, urea and uric acid levels were also increased significantly (P=0.05) compared to normal control group. Changes in serum hepatic enzymes, biochemical parameters and MDA levels induced by CCl4 were reversed by the leaf ethanolic extract of 222 (125 mg/kg) dose. The standard drug silymarin treated group also reversed CCl4-induced changes in biomarkers of liver function and MDA levels. Histopathological studies of the liver samples confirmed the hepatoprotective property of the coded drug 222. It was seen that histopathological damage induced by CCl4 were improved in rat liver, treated with 222 extract. The results of the present study suggested that coded plant (222) leaf ethanolic extract may be used as a hepatoprotective agent against toxic effects caused carbon tetrachloride in the liver.
