Antibiotics are one of the great advances in medicine. But overusing them has led to resistant bacteria (bacteria that are harder to treat). The current study foresees better non-toxic antimicrobial substances (conventional antibiotics) that insist to consider medicinal plants and animal-derived products, which have better antibiotics without any side effects. The goal of this in-vitro study was to evaluate the antimicrobial activity of cotton balls incorporated with and chitosan.
, chitosan, and gentamicin-reinforced cotton balls were considered in three groups namely Group 1, Group 2, and Group 3, which tested against the strains of , and. For the present study, pre-sterilized cotton balls were taken and then soaked with Banana peel extract and soluble chitosan solution at different concentrations of 500 μg/ml, 250 μg/ml, 100 μg/ml, and 50 μg/ml under aseptic conditions and were dried at 50° overnight. The same incorporation method was followed for a 10mg/ml concentration of gentamicin, which was used as a positive control group.
In this current study, the banana peel extract, soluble chitosan, and gentamicin exhibited antimicrobial activity against all the tested microorganisms. In the well diffusion method, at the concentration of 500 μg/ml and 250 μg/ml, chitosan and banana peel extract were comparatively better than the positive control group (gentamicin) at a higher concentration of 10 mg/ml.
From the results of the present study, a lower concentration of the testing group (soluble chitosan and banana peel extract) exhibited a better effect when compared to a higher concentration of gentamicin. Hence, chitosan and banana peel extract impregnated cotton could be preferred for routine clinical scenarios like wounds, extractions sockets, and during any short intraoperative surgical procedures periodontal surgery, where it can provide maximal antimicrobial effects without the side effects of antibiotics.
抗生素是医学领域的重大进展之一。但过度使用抗生素已导致产生耐药细菌(更难治疗的细菌)。当前研究期望能找到更好的无毒抗菌物质(传统抗生素),并坚持考虑药用植物和动物源产品,这些产品具有更好的抗生素且无任何副作用。本体外研究的目的是评估含有香蕉皮提取物和壳聚糖的棉球的抗菌活性。
将含有香蕉皮提取物、壳聚糖和庆大霉素的棉球分为三组,即第1组、第2组和第3组,分别针对金黄色葡萄球菌、大肠杆菌和白色念珠菌菌株进行测试。在本研究中,取预先灭菌的棉球,然后在无菌条件下用不同浓度(500μg/ml、250μg/ml、100μg/ml和50μg/ml)的香蕉皮提取物和可溶性壳聚糖溶液浸泡,并在50℃下过夜干燥。对于浓度为10mg/ml的庆大霉素,采用相同的掺入方法,将其用作阳性对照组。
在本研究中,香蕉皮提取物、可溶性壳聚糖和庆大霉素对所有测试微生物均表现出抗菌活性。在纸片扩散法中,在500μg/ml和250μg/ml浓度下,壳聚糖和香蕉皮提取物比浓度为10mg/ml的阳性对照组(庆大霉素)效果更好。
从本研究结果来看,与高浓度的庆大霉素相比,测试组(可溶性壳聚糖和香蕉皮提取物)较低浓度时效果更好。因此,在伤口、拔牙创口以及牙周手术等任何短时间的术中手术操作等常规临床场景中,含壳聚糖和香蕉皮提取物的棉球可能更受青睐,因为它能在不产生抗生素副作用的情况下提供最大抗菌效果。
