Abstract

Nigella sativa (NS) has been used for many years as an anti-bacterial herbal treatment, such as Methicillin-resistant Staphylococcus aureus, but the mechanism in bacterial elimination is still unknown. IL-1β is a proinflammatory cytokine that helps the immune system eliminate microbes when it enters the body. The purpose of this study was to prove the immunomodulatory effects of Nigella sativa extract through increased IL-1β in dealing with MRSA infections. The design of this study was post-test only control group design using 25 male Balb-c mice infected with MRSA and randomly divided into five groups. Group K was infected with MRSA without being treated. All treatment groups were given NS extracts in different doses for 7 days before being infected with MRSA. P1 was given N. sativa extract 0.05ml, P2 (was given NS extract 0.25ml, P3 was given 0.5ml NS extract, and P4 was given 0.75ml NS. On the 8th day, blood was taken from the retroorbital plexus for IL-1β level examination using ELISA. Statistical tests were done using the One Way ANOVA test. The results showed the mean of IL-1β levels in group K was 11.65ng/L, P1 was 14.07ng/L, P2 was 16.66ng/L, P3 was 18.54ng/L, and P4 was 19.49ng/L which showed an increase in IL-1β levels along with the addition of black cumin dose although there was no difference between groups (p=0.578: ANOVA test). Nigella sativa extract is not proven effective in increasing IL-1β levels of Balb-c mice infected with MRSA.

Abstract

Antimicrobial resistance in pathogens such as Escherichia coli and Staphylococcus aureus poses an urgent global health challenge. Honeybee propolis is known for its promising antibacterial potential.This study aimed to compare the antibacterial effectiveness of propolis against E. coli (Gram-negative) and S. aureus (Gram-positive) using the in vitro disk diffusion method. Propolis was tested at concentrations of 6.25%, 12.5%, 25%, 50%, and 100% against both bacterial species. Disk diffusion assays were conducted on Mueller Hinton Agar, and inhibition zones were measured using a vernier caliper. Data were analyzed using one-way ANOVA. The results showed the Inhibition zone diameters increased with higher propolis concentrations. At 100% concentration, S. aureus showed a 15 mm inhibition zone, while E. coli showed only 7 mm. One-way ANOVA indicated significant differences (p < 0.05) in both bacteria. These findings indicate that propolis exhibits antibacterial activity against both S. aureus and E. coli, with greater effectiveness against Gram-positive S. aureus. These findings support the potential use of propolis as a natural antibacterial agent, particularly for Gram-positive infections.

Abstract

Introduction and Objective: The characteristics, symptoms, and clinical manifestations of pituitary adenoma in Indonesia have not been widely studied. In 26 patients undergoing pituitary surgery at Dr. Kariadi Hospital, we compared visual acuity pre-operative and post-operative from normal and thin optical coherence tomography (OCT) of the retinal nerve fiber layer (RNFL) and ganglion cell layer-internal plexiform layer (GCL-IPL). Method: A retrospective study of the medical record from January 2020 to December 2022 was done. 21 of the 26 patients had surgery by the transsphenoidal route and the rest by craniotomy. All patients had macroadenoma (tumor size >1cm) and were histologically confirmed. Visual acuity before and after surgery was evaluated along with the patient’s OCT value. Result: The thinner pre-operative RNFL thickness was associated with worse visual acuity (VA). Patients with normal RNFL had a median VA of 20/200 while those with thin RNFL had to count their fingers (CF). The patients with normal pre-operative RNFL had a significant improvement in median VA after surgery, from 20/200 to 20/32 (p=0.022), whereas the patients with thin RNFL did not improve (CF to CF, p=0.026). The patients with normal pre-operative GCL-IPL had non-significant improvement in median VA after surgery from CF to 20/20 (p=0.505), also the patients with thin GCL-IPL from CF to 20/200 (p=0.151). Conclusion: The visual recovery after pituitary adenoma surgery is likely to be predicted by pre-operative OCT RNFL. Patients with normal RNFL thickness show an increased tendency in visual recovery after surgery. Keywords: Optical coherence tomography , visual acuity, pituitary adenoma
