OBJECTIVETo evaluate the cytotoxicity and hepatoprotective potentials of extracts, fractions or isolated compound from the leaves of Feronia limonia (F. limonia).

METHODSQualitative phytochemical analysis of extracts, fractions or compound was performed by means of thin layer chromatography and spectroscopic assays. The % purity of compound was measured by analytical HPLC. Extracts, fractions or compound have been individually evaluated for their cytotoxicity effects (10, 20, 100, 250, 500, 750 and 1 000 µg/mL). Based on the inhibitory concentration (IC50) obtained from the cell viability assay, graded concentrations of extracts, fractions or isolated compound were assessed (10, 20, 50, 100, 200 µg/mL) for its hepatoprotective potential against CCl4-induced hepatotoxicity by monitoring activity levels of serum glutamatic pyruvatic transaminase (SGPT) and serum glutamic oxaloacetic transaminase (SGOT).

RESULTSResults indicated that the methanol extract of F. limonia was non-toxic and hepatoprotective in nature as compared with the petroleum ether extract. The acetone fraction of methanolic extract also showed similar properties but the subsequent two fractions were cytotoxic. However, the pure compound isolated from the penultimate fraction of methanolic extract was non-toxic and hepatoprotective in nature. Biochemical investigations (SGOT, SGPT) further corroborated these cytological observations.

CONCLUSIONSIt can be concluded from this study that F. limonia methanol extract, some fractions and pure isolated compound herein exhibit hepatoprotective activity. However, cytotoxicity recorded in the penultimate fraction and investigation of structural details of pure compound warrants further study.

Introduction: Osteoarthritis (OA) is estimated to be the fourth leading cause of disability in the general population. It probably is the most common disease of joints in adults throughout the world. Knee OA accounts for more than 80% of the disease’s total burden and as per an estimate in US population, it affects at least 19% of adults aged 45 years and older. This was a randomised study aimed to evaluate the efficacy of platelet rich plasma (PRP) as a treatment modality for osteoarthritis knee in comparison to arthroscopic management. Materials and methods: This study was conducted from 2018 to 2020 at a tertiary care teaching hospital, under reference number ELMC&H/RCELL2019/39. A total of 70 patients of osteoarthritis knee with grade 2-3 according to the Kellgren-Lawrence classification were selected using computer generated random number among them 35 patients were subjected to arthroscopy (Group II) and 35 were administered platelet rich plasma injection (Group I) and evaluated at 3, 6 and 9 months of follow-up. Both the groups were assessed and scored with the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Visual Analog Pain Scale (VAS) to compare pre-treatment and post-treatment values. As all the patients in the sample was followed-up, resulting into no loss of subjects. Result: Overall, percentage reduction in VAS score at 3 months, 6 months, and 9 months was 24.45±9.09, 18.45±11.60 and 8.29±14.19%, respectively in Group I and 18.96±5.85, 7.33±8.60 and 3.20±7.39%, respectively in Group II. A statistically significant difference between two groups was observed at 3- and 6-months’ time intervals only (p<0.05). Overall, percentage reduction in WOMAC score at 3 months, 6 months and 9 months was 24.03±11.41, 17.45±9.24, and 9.49±9.80%, respectively in Group I and 11.27±5.73, 5.70±4.78, and -0.13±5.06%, respectively in Group II. At all the three-time intervals, the difference between two groups was significant statistically (p<0.001). Conclusion: This study suggested that both PRP as well as arthroscopy provide a reduction in WOMAC and VAS scores for pain among cases of knee osteoarthritis. Most effective reduction is observed at three months follow-up which thereafter tends to diminish. Of the two modalities, PRP seemed to have an edge over arthroscopic debridement, however, this efficacy was more pronounced for KellgrenLawrence Grade 2 as compared to Grade 3.
