The analytic method modified from a standard method was validated for linearity, coefficient of variation, intra-day and inter-day precision, and recovery rate. The retention time of rifampicin was reduced from 18.3 to 3.1 minutes after the method was modified. To validate the method, the coefficient of determination was determined for the linearity to be between 0.975 and 0.998, the coefficient of variation ranged between 2.8% to 15.5% for both intra-day and inter-day precision. Recovery rates ranged between 87% and 125%. The results indicated that the analytical method developed was valid, precise and feasible, and could be useful for quantitatively determining rifampicin plasma drug concentration in TB patients.","PeriodicalId":194477,"journal":{"name":"Journal of Pharmacy & Bioresources","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139316732","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}

Numerous conventional medications are available for the management of RA. However, their usage is limited due to the associated side effects. Spondias mombin is a member of the Anacardiaceae family known for its anti-arthritic effects. This study aimed to evaluate the anti-arthritic activity of S. mombin (L.) stem bark in RA. Radical scavenging activity was determined using DPPH assay. The anti-inflammatory effect was determined using protease inhibition and formaldehyde-induced arthritis models. S. mombin aqueous fraction (SMAF) exhibited a significant (p<0.0001) radical scavenging effect (IC50 of 57.87 µg/mL) over the S. mombin methanol extract (SMME) and S. mombin chloroform fraction (SMCF) when compared to the sham control. SMAF at 500 µg/mL significantly (p<0.05) inhibited (56.89 ± 2.02%) the effect of protease when compared to the sham control. SMME significantly (p<0.001) reduced inflammation in rat paws when compared to the control with peak effects seen at the dose of 50 mg/kg body weight.

This study investigated the toxicity profile of hydroethanolic extract of E. tremula (HEET) in Wistar rats. Acute and sub-acute (28 days at doses of 250, 500 and 1000 mg/kg per oral) toxicity tests were conducted using OECD 425 and 407 guidelines respectively. Limit test at 5,000 mg/kg was conducted to ascertain the midpoint lethal dose (LD50). The LD50 of HEET was above 5000 mg/kg per oral and no significant alterations in haematological parameters and tissue morphology were observed. In the sub-acute study, no death was recorded. There were no changes in food intake, organ/body weight, lipid profile, liver and renal function indices. However, histology of the kidneys showed slight tubular adhesion and glomerular necrosis. HEET was practically safe after acute administration with no practical deleterious effect at 250 mg/kg after prolonged administration in rats. However, 28 days administration of high doses caused slight kidney injury.","PeriodicalId":194477,"journal":{"name":"Journal of Pharmacy & Bioresources","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139316758","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}

Drosophila melanogaster aged 3-5 days old were exposed to different concentrations (5-1000 mg/ 5 g diet) of isoniazid, and extract for 7 days to determine the lethal concentration (LC50). A 14-day survival assay was performed to evaluate the effect of isoniazid and the herbal extract on the survival rate of Drosophila melanogaster. The antioxidant activity of the herbal extract on the stable 2,2- diphenyl-1- picrylhydrazyl (DPPH) was also evaluated. The result showed an antioxidant activity greater than that of a standard, silymarin. An increase in survival rate of the fruit flies was observed at the lowest dose of the extract, when compared to those fed diet only. In conclusion, this study provided valuable insights into the antioxidant properties of the herbal extract, highlighting its potential benefits, while further research to elucidate the effects of phytochemicals especially at high doses is necessary.

The phytochemical screening revealed the presence of flavonoids, steroid, triterpenes and saponins.

The extract exhibited highest percentage inhibition of writhing (99.24%) at a dose of 1000 mg/kg. However, the extract showed no central analgesic activity.

Groups C, D, and E were given varying doses of vitamin C, and Groups F, G, and H received alcohol followed by vitamin C treatments. After twenty-one days, blood samples were collected and analyzed for various markers. Rats receiving alcohol only showed increased white blood cell count (WBC), platelet count (PLT), neutrophil to lymphocyte ratio (NLR), and platelet to lymphocyte ratio (PLR), along with decreased antioxidant enzyme activity. However, rats receiving vitamin C alone or in combination with alcohol exhibited reduced inflammatory markers and increased antioxidant activity compared to the alcohol-only group. The study demonstrated that commercial-grade vitamin C at doses of 100 mg/kg, 200 mg/kg, and 300 mg/kg effectively reduced chronic low-grade inflammation.
