Several studies have shown anti-inflammatory, anti-microbial, antifungal, and antioxidant effects from -peel essential oil (Cl-PEO). Cl-PEO can be developed as topical drugs for oral ulceration because of its potential active components. There have been no studies on the topical application of Cl-PEO inducing type IV hypersensitivity reaction.
To investigate the potential of Cl-PEO from Batu City to induce type IV hypersensitivity reactions based on clinical changes, lymphocytes, macrophages, IFNγ, andIL10 expression.
This study was adapted from a guinea pig maximization-test method in Indonesia and the guidance of ISO 10,993-10:2010, and conducted on 20 guinea pigs () divided into a control group and a treatment group. The treatment group was given Cl-PEO and the control group CMC-Na. Clinical changes were observed, then tissue specimens taken for hematoxylin-eosin and immunohistochemistry staining.
There were no clinical changes after exposure. Lymphocyte and macrophage numbers and IFNγ and IL10 expression increased in the treatment group compared to the control group (=0).
Cl-PEO can induce type IV hypersensitivity reactions in guinea pigs based on cellular and molecular cytokines, but there are no clinical changes after topical application.
多项研究表明,-果皮精油(Cl-PEO)具有抗炎、抗菌、抗真菌和抗氧化作用。由于其潜在的活性成分,Cl-PEO可开发为治疗口腔溃疡的局部用药。目前尚无关于Cl-PEO局部应用诱导IV型超敏反应的研究。
基于临床变化、淋巴细胞、巨噬细胞、IFNγ和IL10表达,研究峇都市的Cl-PEO诱导IV型超敏反应的潜力。
本研究采用印度尼西亚豚鼠最大化试验方法并遵循ISO 10,993-10:2010的指导,对20只豚鼠()进行实验,分为对照组和治疗组。治疗组给予Cl-PEO,对照组给予羧甲基纤维素钠(CMC-Na)。观察临床变化,然后采集组织标本进行苏木精-伊红染色和免疫组织化学染色。
暴露后无临床变化。与对照组相比,治疗组的淋巴细胞和巨噬细胞数量以及IFNγ和IL10表达增加(=0)。
基于细胞和分子细胞因子,Cl-PEO可在豚鼠中诱导IV型超敏反应,但局部应用后无临床变化。
