Kawasaki disease is far more frequent in children than in adults. The pathogenesis of Kawasaki disease is unknown, but it involves changes to the coronary artery and other diverse clinical manifestations. There are currently no specific laboratory diagnostic indexes, and especially since the disease is rare in adults, so it is extremely easy to misdiagnose or to overlook entirely. Our retrospective analysis of an diagnosis of and treatment for Kawasaki disease in an adult provides a guide to clinical doctors in terms of understanding Kawasaki disease, early diagnosis of it, and improved prognosis.

OBJECTIVETo investigate the mechanism of lemon peel essential oil (LPE) on the cariogenicity of Streptococcus sobrinus (Ss).

METHODSLPE was extracted by the authors, and the minimum inhibition concentration (MIC) was measured by disc diffusion method. The LPE was used as the experimental group with concentrations ranging from 2.250 g/L to 0.281 g/L prepared with trypticase peptone yeast (TPY) culture medium, and TPY culture medium was used as the control group. Ss at the concentration of 10(8) CFU/ml was added to each group, and cultured for 6, 18, 24, 48 hours. Neson-Somogyi method was used to measure the content of reducing sugar, and glucosyltransferase (GTF) activity. The activity of lactate dehydrogenase (LDH) was measured by lactic acid and pyruvic acid continuous monitoring method. The content of water insoluble glucan (WIG) was measured by anthrone method, and the pH value of the culture solution was detected. The value of pH before the experiment and the time difference was alculated as ΔpH.

RESULTSAt the same time point, the activity of GTF and LDH and the concentration of WIG and the value ΔpH decreased gradually with the increase of concentration of LPE. There were significant differences between each experimental group and control group (P < 0.01). The control group had the maximum value, GTF: (6.71 ± 0.61) mIU, LDH: (135.8 ± 1.7) U/L, WIG: (47.15 ± 5.12) mg/L, ΔpH: (2.67 ± 0.01). The highest drug concentration group had the minimum value: GTF: (0.39 ± 0.07) mIU, LDH: (95.0 ± 5.4) U/L, WIG: (2.44 ± 0.38) mg/L, ΔpH: (0.61 ± 0.01).

CONCLUSIONSThe LPE below the MIC could still inhibit the GTF, LDH activity and lead to the decrease of WIG and the acid production.
