Objective: This study’s aim was to assess the efficacy of topical Binahong (Anredera cordifolia (Ten.) Steenis) leaf ethanolic extract administration on serum transforming growth factor-beta 1 (TGF-β1) in infected wounds. Methods: An experimental study, in vivo, was conducted in the Biotechnology Laboratory and Animal House, Faculty of Medicine, Universitas Sriwijaya, Palembang, from July to September 2020. There were 30 male Wistar rats aged 10–12 weeks with excisional wounds infected with Staphylococcus aureus ATCC 25923. The rats were divided into five groups and received three concentrations of Binahong leaf extracts (2.5%, 5%, and 10%), salve base, and povidone iodine 10% topically twice daily for 14 days. Serum was obtained before treatment and after 14 days of treatment. Wound area and bacterial count were also recorded and analyzed. Data analysis was performed using computer software. Results: Wound size and bacterial count were significantly decreased in treatment groups receiving topical Binahong leaf ethanolic extract. No significant increase in serum TGF-β1 was observed in all treatment groups. Conclusion: Topical administration of Binahong leaf ethanolic extract on rats with infected wounds for 14 days did not significantly increase serum TGF-β1.

Polymorphisms of the progesterone receptor gene alter the expressions of two receptor isoforms involved in the regulation of progesterone's antiproliferative effect in endometriotic tissue. This study aims to identify the +331G/A polymorphism of the progesterone receptor gene in endometriosis patients in Palembang, South Sumatra. Identification of +331G/A single-nucleotide polymorphism (SNP) was conducted on 42 endometriosis patients through polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). In this study, twenty-six (61.9%) subjects had heterozygous mutant genotype for the +331G/A SNP. No subject with homozygous mutant genotype for the +331G/A polymorphism was identified. The frequencies of polymorphic alleles for the +331G/A polymorphism was 30.9%. In conclusion, the +331G/A progesterone receptor gene polymorphism was present in endometriosis patients in Palembang, South Sumatra. This finding may warrant further studies to determine whether this polymorphism play a role in the development of endometriosis in the Indonesian population.
