Abstract

BACKGROUND AND OBJECTIVES

Diabetes is a metabolic disorder characterized by elevated glucose levels, leading to complications such as infections and impaired wound healing. Diabetic wounds are prone to bacterial infections, with common pathogens including and Coelomic fluid of (CFEF) exhibits antimicrobial properties, making it a potential alternative to traditional antibiotics. This study aims to evaluate the in vitro antibacterial effects of CFEF on diabetic wound pathogens, alongside analyzing its protein content and antioxidant activities.

MATERIALS AND METHODS

This study used bacterial strains ATCC 25923, ATCC 25922, ATCC 19659, and ATCC 27853. CFEF was extracted using warm water and electric shock methods. Protein concentration was determined using the Bradford method, and protein analysis was conducted via Tricine SDS-PAGE. Antioxidant activities were evaluated using DPPH, FRAP, superoxide dismutase, and catalase assays. Antibacterial activities were tested by disc diffusion, MIC, and MBC methods.

RESULTS

The study showed that CFEF exhibited significant antibacterial and antioxidant activities against common bacteria found in diabetic wound infections. The warm water shock method yielded superior results compared to the electric shock method.

CONCLUSION

CFEF demonstrates promising antibacterial and antioxidant properties, suggesting its potential as a natural alternative for treating diabetic wound infections. Further research is needed to evaluate its clinical application and safety.

摘要

背景与目的

糖尿病是一种以血糖水平升高为特征的代谢紊乱疾病,可导致感染和伤口愈合受损等并发症。糖尿病伤口易发生细菌感染,常见病原体包括[具体病原体1]和[具体病原体2]。[生物名称]的体腔液(CFEF)具有抗菌特性,使其成为传统抗生素的潜在替代品。本研究旨在评估CFEF对糖尿病伤口病原体的体外抗菌作用,并分析其蛋白质含量和抗氧化活性。

材料与方法

本研究使用了细菌菌株[菌株1名称]ATCC 25923、[菌株2名称]ATCC 25922、[菌株3名称]ATCC 19659和[菌株4名称]ATCC 27853。采用温水法和电击法提取CFEF。使用Bradford法测定蛋白质浓度,并通过Tricine SDS-PAGE进行蛋白质分析。使用DPPH、FRAP、超氧化物歧化酶和过氧化氢酶测定法评估抗氧化活性。通过纸片扩散法、MIC和MBC法测试抗菌活性。

结果

研究表明,CFEF对糖尿病伤口感染中常见细菌具有显著的抗菌和抗氧化活性。与电击法相比,温水冲击法产生了更好的结果。

结论

CFEF显示出有前景的抗菌和抗氧化特性,表明其作为治疗糖尿病伤口感染的天然替代品的潜力。需要进一步研究以评估其临床应用和安全性。
