To estimate and compare the level of serum immunoglobulin A in patients of oral submucous fibrosis (OSMF), leukoplakia, and control group.
OSMF is a well-recognized potentially malignant condition in the oral cavity, and a transformation rate as high as 7.6% over a period of 10 years has been reported from India. Leukoplakia has evolved as a clinico-pathologic concept over many years, with the current clinical designation being accepted worldwide.
Quantia IgA is a turbidometric immunoassay for the detection of IgA in human serum and is based on the principle of agglutination reaction. The test specimen is mixed with the activation buffer (R1) and then with antihuman IgA reagent (R2) and allowed to react. For the estimation of serum IgA, 500 μl of Quantia IgA activation buffer R1 is taken in a clean test tube. Serum sample is diluted in the ratio of 1:5 with normal saline. Ten microliters of diluted serum sample are added to R1. After incubation for 10 min, 50 μl of R2 is added, which is Quantia IgA antihuman IgA reagent to the sample, and the reading is recorded at wavelength 340 nm at 37°C. The level of IgA will be estimated by a semi-automatic biochemical analyzer machine and then data analysis will be done.
The immunologic alterations observed by us in OSMF and leukoplakia are almost similar or nearer to the alterations observed in oral cancer, so it is reasonable to assume that OSMF and leukoplakia can be an intermediate stage in the transformation process of a normal cell to oral malignancy.
Prevention and early detection is the best way to reduce the incidence and mortality of premalignant disorders and oral cancer. There are many ways and methods of early detection of premalignant disorders and oral cancer, and the immunological method is one of them.
评估并比较口腔黏膜下纤维化(OSMF)患者、白斑患者及对照组的血清免疫球蛋白A水平。
OSMF是口腔中一种公认的潜在恶性疾病,印度报道其在10年期间的恶变率高达7.6%。白斑多年来已发展成为一个临床病理概念,目前的临床命名已被全球接受。
Quantia IgA是一种用于检测人血清中IgA的比浊免疫分析方法,基于凝集反应原理。将测试样本与激活缓冲液(R1)混合,然后与抗人IgA试剂(R2)混合并使其反应。为了评估血清IgA,在干净的试管中加入500μl Quantia IgA激活缓冲液R1。血清样本用生理盐水按1:5的比例稀释。将10μl稀释后的血清样本加入R1中。孵育10分钟后,加入50μl R2,即Quantia IgA抗人IgA试剂到样本中,并在37°C下于波长340nm处记录读数。IgA水平将通过半自动生化分析仪进行评估,然后进行数据分析。
我们在OSMF和白斑中观察到的免疫改变几乎与口腔癌中观察到的改变相似或更接近,因此有理由假设OSMF和白斑可能是正常细胞向口腔恶性肿瘤转变过程中的中间阶段。
预防和早期检测是降低癌前疾病和口腔癌发病率及死亡率的最佳方法。早期检测癌前疾病和口腔癌有多种途径和方法,免疫方法是其中之一。
