Multidrug-resistant Pseudomonas aeruginosa is one of the pathogenic bacteria associated with wound infections. \u0000Aim: This study isolated and identified multidrug-resistant Pseudomonas aeruginosa from infected wounds and determine the antibacterial activity of Lawsonia inermis leaf extracts against it. \u0000Design: This is a Clinical and laboratory-based study involving patients with defined cases of wound infections. \u0000Place and Duration of Study: This study was conducted in the Microbiology (Bacteriology) laboratory of Specialist Hospital, Bauchi, Nigeria, from February to November 2021. \u0000Methods: Twenty-eight (28) Pseudomonas aeruginosa isolates were recovered from 179 wound swabs using standard laboratory procedures and were screened for multidrug-resistant patterns according to the Kirby-Bauer disc diffusion method. Antibacterial efficacy of the aqueous, ethanolic, and methanolic leaf extracts of Lawsonia inermis was tested against the multidrug-resistant isolates using agar well diffusion techniques. The zone of inhibition was measured and the differences between means were statistically analyzed (p<0.05). \u0000Results: A total of twenty-eight (28) multidrug-resistant Pseudomonas aeruginosa were confirmed, showing resistance to Amoxicillin (64.3%), Ceftazidime (85.71%), and Cefotaxime (78.57%) but sensitivity to Imipenem (95.5%). The phytochemical screening revealed the presence of flavonoids, glycosides, saponins, steroids, and tannins among others. MDR P. aeruginosa was inhibited at varied concentrations of the extracts with the diameter mean zone of inhibition increasing as the concentration increased. The Methanol extracts showed the highest antibacterial activity against MDR P. aeruginosa with a mean zone of inhibition of 9.500±0.288mm at 400mg/ml. \u0000Conclusion: These results indicated that Lawsonia inermis leaf extracts possess antibacterial activities on Multidrug-resistant Pseudomonas aeruginosa which could be a good source for the production of plant-based antibacterial drugs., although somewhat less than the synthetic standard drugs (Imipenem) having a mean of 13.83±0.288mm.","PeriodicalId":11969,"journal":{"name":"European journal of medicinal plants","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77193122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Obesity contributes to the emergence of several diseases such as type-2 diabetes mellitus, hypertension, cardiovascular disorders, cancer, and non-alcoholic fatty liver. A number of studies report that natural ingredients have the potential to be used as a treatment for obesity while reducing a fatty liver. The aim of this research is to evaluate the activity of red spinach ethanol extract in reducing the accumulation of fatty liver in diet-induced obese zebrafish based on its histopathological profile. \u0000Methodology: Zebrafish must be adapted for 2 weeks. After 2 weeks, the zebrafish were divided into 6 groups which included:  the normal group (or negative control); the obesity group (positive control group); the standard drug (orlistat with dose 4.5 µg/ml); the EERS group (dose of 50 µg/ml); the EERS group (dose of 100 µg/ml); and the EERS group (dose of 200 µg/ml). For a period of 4 weeks, the normal group received a standard diet. A positive control group received Artemia. The treated group received Artemia which was combined with the administration of red spinach (preventive method). The obese group and extract-treated group were given 60 mg/group/fish in the experimental diet. \u0000Results: The results showed that EERS at a dose of 100 µg/ml did not show any fatty liver based on their histopathological profile. The EERS dose of 200 µg/ml is more effective in reducing fatty liver when compared to doses of 50 µg/ml and 100 µg/ml on obese zebrafish. \u0000Conclusion: Based on the results of the study, it can be concluded that EERS is very prospective for further research and development as a drug for treating obesity and reducing fatty liver.","PeriodicalId":11969,"journal":{"name":"European journal of medicinal plants","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87390542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, the assays of polyphenols and flavonoids were carried out in order to quantify the contents of these two compounds in each extract. Finally, the antioxidant activity of the extracts was evaluated by three methods: the CUPRAC method, the trapping of the 2,2-diphenyl-1-picryl-hydrazyl radical (DPPH•) and the trapping of the ABTS•+ radical-cation (2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid)). The best antioxidant activities were obtained with the ABTS•+ radical scavenging with IC50 of 0.13 mg/mL for the aqueous extract and 0.19 mg/mL for the isopropanol extract.

More glaring is the paucity of information on the histomorphological effect of the plant’s aqueous leaf extract hence the need to determine possible alteration of tissue structures in reproductive organs of adult Wistar rats  which may affect their functions. \u0000This study aimed at determining the effect of Momordica charantia aqueous leaf extract (MCALE) on the reproductive organs of experimental adult Wistar rats. \u0000Materials and Methods: Twenty five rats (male and female) weighing 180-200g were randomly divided into five (5) groups of five rats each.  The experimental groups, A to D were fed on standard diet and administered with 100, 200, 400 and 800 mg/kg body weight /day of MCE orally using gavage for 30 days.  Rats in the control groups were fed on standard diet and physiological saline orally. Organs were harvested, fixed in 10% neutral buffered formalin (ovaries) and Bouin’s fluid (testes), embedded in molten paraffin wax, sectioned with a rotary microtome and stained with the haematoxylin and eosin technique.  Stained slides were examined using the Olympus microscope.  \u0000Results: Sections of ovaries administered 100 mg/kg of the extract showed vesicular spaces in corpus luteum and enlarged blood vessels.  Sections treated with 200 mg/kg revealed follicular cyst and mild vacuolation of zona granulosa. Sections of the ovaries administered 400 mg/kg revealed degenerative changes, follicular cyst, mild vacuolation and reduction of zona granulosa layer while those treated with 800 mg/kg showed severe vacuolation of the zona granulosa layer.  \u0000Conclusion: Momordica charantia caused histomorphological changes in ovaries of Wistar rats which could cause hormonal imbalance and infertility in females. No histomorphological changes were observed in male testes.","PeriodicalId":11969,"journal":{"name":"European journal of medicinal plants","volume":"353 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82606489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
