ABSTRACTObjective: To assess the anticonvulsant activity of ethanolic extract of Citrus maximus (EECM) leaves of maximal electroshock seizure (MES) andpentylenetetrazol (PTZ)-induced seizure models on albino (Wistar strain) rats and mice.Methods: Anticonvulsant activity was carried out by MES model and PTZ-induced clonic convulsions model; in each model, albino rats (Wistar strain)of either sex were taken and divided into five groups, each consisting of 6 rats. One group was used as control (3% w/v gum acacia), one as standard(phenytoin), and three groups for the test drug of EECM leaves (doses of 50, 100, and 200 mg/kg) treatment. The reduction in time or abolition of tonicextensor phase of MES-convulsions was recorded for all the animals. In PTZ model, either delay or complete abolition of convulsions in rats treatedwith diazepam and EECM leaves was noted for all the animals.Result: EECM leaves reduced the extensor phase of convulsion in MES in a dose-dependent manner and decrease in the duration of convulsions in PTZmodel with increasing dose. Anticonvulsant activity was seen maximum at the dose of 200 mg/kg.Conclusions: Thus, from the above two seizure models of MES and PTZ, it can be concluded that EECM leaves have got an anticonvulsant effect in anincreasing dose-dependent manner.Keywords: Anticonvulsant, Citrus maximus, Maximal electroshock seizure, Pentylenetetrazol.

AbstractThe present study was designed to look at the hematological disorders in gentamicin nephrotoxicity model, as kidney is considered as one of the hemopoietic organs. In a previous study, novel and classical kidney injury biomarkers were utilized to evaluate the nephroprotective potential of Carica papaya leaf extract (CPLE) in the same model in albino rats. Gentamicin (100 mg/kg, subcutaneously, for 21 consecutive days) resulted in significant decreases in red blood cell (RBC) count, hemoglobin concentration (HGB), and packed cell volume (PCV) value, with minimal alterations in erythrocytic indices. Leucogram showed leukocytosis, granulocytosis, and thrombocytopenia. Erythropoietin (EPO) levels were also drastically decreased by the end of the experimental course. Serum iron, unsaturated iron-binding capacity (UIBC), total iron binding capacity (TIBC), transferrin saturation %, and serum transferrin concentration values were significantly decreased in contrast to ferritin, which was increased. When concurrently administered with gentamicin, CPLE (150 and 300 mg/kg, orally via gastric tube, for 21 days) significantly protected against the drastic effects of the former on the blood profile with improving potentials on erythrogram, leukogram, thrombocytes, EPO, iron and its indices, in a dose-dependent manner. These data may suggest CPLE as an appreciated blood homeostatic and nephroprotective agent from a natural source that could be a good remedy in conditions associated with blood disorders.

Abstract The present study investigates the hepatoprotective and nephroprotective potentials of Mucuna pruriens leaf extract with a view to providing a potent alternative in the management of liver and kidney diseases. Forty male albino rats were randomly placed into eight groups comprising five animals each. Animals in group I were administered with the distilled water, while groups II and VI were exposed to CCl4 and rifampicin respectively. Animals in groups III and IV were initially exposed CCl4 and treated with 50 and 100 mg/kg bw M. pruriens respectively. Similarly, groups VII and VIII animals were exposed to rifampicin and treated with 50 and 100 mg/kg bw M. pruriens respectively. Animals in group V were treated with 100 mg/kg bw silymarin by oral gavage after an initial exposure to CCl4. Selected biomarkers of liver and kidney damage were determined in the serum and organs homogenate. Liver and kidney slices of experimental animals were also stained for histopathological examination. Exposure to CCl4 and rifampicin respectively resulted in marked distortion in lipid profile, inhibition of antioxidant enzymes and a surge in ALT, AST, ALP, urea, uric acid, bilirubin and creatine kinase. Treatment with M. pruriens extract reversed all deranged biochemical and histopathological parameters in a dose-dependent manner. Restoration of both biochemical and histopathological alterations established the fact that M. pruriens is a potent hepatoprotective and nephroprotective plant, thereby giving credence to the potential usefulness of its leaf extract in the management of liver and kidney diseases.

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

Tissue Samples

The present study is aimed at utilization of novel and classical kidney function biomarkers to evaluate the nephroprotective potential of Carica papaya leaf extract (CPLE) in gentamicin nephrotoxicity model in albino rats. The used classical biomarkers were urea and creatinine; while the new biomarkers were Kidney injury molecule-1 (KIM-1) and Clusterin. Forty-five male albino rats were assigned into five groups and subjected to different treatments for nine consecutive days (vehicles; gentamicin, 100 mg/kg, subcutaneously; ascorbic acid, 200 mg/kg, orally; CPLE, 150 and 300 mg/kg b wt., orally). Three rats/group were killed on days 3, 6, and 9 for blood and tissue samples for renal and oxidation markers. Gentamicin resulted in significant increase in urea and creatinine only by the end of the experimental course; while the novel biomarkers were evident as early as 3 days upon gentamicin injection. When concurrently administered with gentamicin, CPLE significantly protected kidney tissues against gentamicin nephrotoxic effects indicated by decrement of both the novel and the classical standard biomarkers, in a dose-dependent manner. CPLE-mediated protection was attributed to its antioxidant potential indicated by significant inhibition of malondialdehyde (MDA) levels in both serum and kidney homogenates. The results were further supported by histopathological examination that revealed considerable amelioration of the pathological microscopic alterations induced by repeated gentamicin injection. Phytochemical analysis of CPLE indicated presence of tannins and flavonoids. These data may suggest CPLE, based on improvement of both classical and novel renal markers, as a highly potent nephroprotective and antioxidant from natural source that could be a good remedy in conditions associated with renal disorders.

Background: Lavana is used as medicine as well as Ahara since ancient times. In Caraka Samhita it has been mentioned that three Dravyas viz. Pippali, Kshara (alkali) and Lavana (salt) can be used as emergency medicine, but they should not be consumed in excess (Ati Upayunjita). Hence in the present study Lavana has been evaluated in experimental animals in two different phases’ viz. Acute administration at graded doses as part of acute toxicity study and Sub-Acute administration at fixed dose level, as part of toxic Sub-Acute toxicity study, to assess the possible adverse effects. Materials andamp; Methods: Wistar strain albino rats of either sex weighing between 150 - 200g. body weights were used, The experiment was carried out in accordance with the direction of the Institutional animal ethics committee (IAEC) after obtaining its permission (Approval number IAEC – 138/k/2018). Results: Results were drawn based on histopathological reports and biochemical reports of each group of toxicity study. Acute toxicity study has been carried out in albino rats receiving the 2 dose level maximum at up to 10 times higher (855mg/kg) then the therapeutic equivalent dose (427.5mg/kg). In Sub-Chronic toxicity: dose given was five times higher than therapeutic equivalent dose and ten times the equivalent to human therapeutic dose for duration of 30 days. Discussion: Toxicity is not found in Acute study and in Sub-Acute study moderate to high toxicity is found.

Background: Tulsi (Ocimum sanctum L.) common household plant, a potent adaptogen has been used for its medicinal property for many years. It is known in Ayurveda as Incomparable one, Mother of medicine of Nature and The Queen of Herbs. The present study evaluated the stress induced anti-ulcer effect of tulsi leaves in albino rats.Methods: Albino rats were randomly, allocated to different experimental groups and aqueous leaf extract of Tulsi (Ocimum sanctum) is given for 7 days. Gastric ulcers were induced by cold restrain methods and results were compared with control using distilled water and standard drug Ranitidine.Results: The Anti-ulcer effect of aqueous extract of Tulsi was significant in a dose dependent manner with cold restraint model. The percentage of ulcer protection of Tulsi leaf extract at dose 100mg/kg is 68.85% and at dose of 200mg/kg showed 65.66% and the standard drug Ranitidine showed 78.23% ulcer protection which is significant (p <0.05).Conclusions: The study showed that when Tulsi (Ocimum sanctum) is given at dose 100-200mg/kg for 7 days i.e., pre-treatment in rats for anti-ulcer effect, it caused a significant reduction in the ulcer scores and ulcer index when compared with control group, as evidenced by the gross appearance and histological findings of gastric mucosa in rats. There were few signs of mucosal injury and the percentage of damage was less compared to control group. Serosal surface revealed very few dilated blood vessels and petechial hemorrhages and mucosal surface had few ulcers of varying sizes.

Anti Inflammatory

AbstractThe leaves of Piliostigma thonningii are used in traditional medicine in Benin to treat inflammatory skin diseases and infections. So far, pharmacological studies of the anti-inflammatory and anti-infective effects of phytochemically characterized extracts of P. thonningii have been very limited. Therefore, we investigated the in vitro anti-inflammatory and antimicrobial effect of P. thonningii leaf extracts and analyzed the phytochemical composition of extracts of different polarities (water, 50% ethanol, and n-hexane). Quercetin-3-O-rhamnoside was confirmed as the main flavonoid in the polar extracts. GC-MS analysis identified 20 constituents of the aqueous extract and 28 lipophilic compounds of the n-hexane extract by comparison with authentic standards and spectral library data. The aqueous P. thonningii leaf extract inhibited the IL-8 and IL-6 secretion in TNF-α-stimulated HaCaT cells in a concentration-dependent manner with IC50 values of 74 µg/mL for IL-8 and 89 µg/mL for IL-6. However, an inhibitory effect of the identified quercetin-3-O-rhamnoside and its aglycone, quercetin, on the release of IL-8 and IL-6 could not be demonstrated. In the antimicrobial screening, inhibition zones for a 50% EtOH leaf extract of P. thonningii were found for Staphylococcus epidermidis, Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, and Escherichia coli. For none of the microbial strains, however, the MIC was below 500 µg/mL, so that the antibacterial activity must be classified as low. As a result, our investigations primarily support the ethnomedical use of P. thonningii leaf extracts in topical inflammatory conditions. Further studies are required to identify the compounds responsible for the in vitro anti-inflammatory effects.

The main purpose of this study is to investigate the role of citrus leaf extract in carbon tetrachloride-induced hepatic injury and its potential molecular mechanism. Carbon tetrachloride was used to construct hepatic injury animal model. To this end, rats were randomly divided into 4 groups: control, carbon tetrachloride-treated, and two carbon tetrachloride + citrus leaf extract-treated groups. The results show that citrus leaf extract treatment significantly reversed the effects of carbon tetrachloride on the body weight changes and liver index. Besides, treatment with citrus leaf extract also reduced the levels of serum liver enzymes and oxidative stress in a dose-dependent manner. H&E staining and western blotting suggested that citrus leaf extract could repair liver histological damage by regulating AMPK and Nrf-2.
