Abstract

This research aimed to know the antibacterial activities of bidara leaf extract against Staphylococcus aureus isolated from mastitis cases. The isolate was identified before the antibacterial test. This study was done by five times repetitions on Mueller Hinton Agar. The concentrations used in this study were 30%, 40%, and 50% of bidara leaf extract then a blank disc was dipped into each concentration. Tetracycline disc was used as a positive control and aquadest was used as a negative control. The diameter of the clear zone was measured using calipers after incubation for 24 hours at 37℃. The results showed significant differences (p<0.05) between the positive control (K+), negative control K (-), and the concentration group. However, each concentration of bidara leaf extract showed insignificant differences in the diameter of the clear zone. It could be concluded that bidara leaf extract has antibacterial activities against Staphylococcus aureus isolated from mastitis cases.

Abstract

Kidney damage caused by high-dose paracetamol leads to elevated Blood Urea Nitrogen (BUN) and creatinine levels as indicators of impaired renal function. This study aimed to evaluate the dose-dependent nephroprotective effects of ethanolic Carica papaya seed extract on BUN and creatinine levels in paracetamol-induced albino rats. A posttest-only control group design was applied using 25 male Wistar rats divided into five groups: negative control (1% CMC-Na), positive control (paracetamol 1000 mg/kgBW), and three treatment groups receiving Carica papaya seed extract at doses of 100, 200, and 400 mg/kgBW. The extract was administered orally for seven consecutive days before paracetamol induction on day 8 and continued until day 11. Blood samples were collected on day 11, and serum was stored at -20 °C before BUN and creatinine concentrations were analyzed spectrophotometrically. Data were statistically analyzed using one-way ANOVA followed by Duncan’s Multiple Range Test (DMRT) at a significance level of p < 0.05. The results showed a significant and dose-dependent reduction in both parameters in all treated groups compared to the positive control, with the 400 mg/kgBW dose showing the strongest effect and restoring values close to physiological levels. The nephroprotective activity was associated with the antioxidant and anti-inflammatory mechanisms of the bioactive compounds that counteract oxidative stress and preserve renal cellular integrity. In conclusion, the ethanolic extract of Carica papaya seeds demonstrates significant dose-dependent nephroprotection against paracetamol-induced kidney injury in rats.
