Condylar hyperplasia: An updated review of the literature
Luis Eduardo Almeida,Joseph Zacharias,Sean Pierce 대한치과교정학회 2015 대한치과교정학회지 Vol.45 No.6
Condylar hyperplasia (CH) is a rare disorder characterized by excessive bone growth that almost always presents unilaterally, resulting in facial asymmetry. Classification of the different types of CH can differ depending on the authors. Correct diagnosis is critical in determining the proper treatments and timing. This paper is a review of the recent literature on the epidemiology, etiology, diagnosis, classification, and surgical treatments of CH.

<P>Phytochemical study on an EtOAc-soluble extract of the root bark of <I>Erythrina mildbraedii</I> resulted in the isolation of six prenylated flavonoids 1—6. Based on physicochemical and spectroscopic analyses, their structures were determined to be new natural products licoflavanone-4′-<I>O</I>-methyl ether (1), 2′,7-dihydroxy-4′-methoxy-5′-(3-methylbut-2-enyl)isoflavone (2), and (3<I>R</I>)-2′,7-dihydroxy-3′-(3-methylbut-2-enyl)-2‴,2‴-dimethylpyrano[5‴,6‴ :4′,5′]isoflavan (3), along with three known compounds erythrinin B (4), abyssinin II (5), and parvisoflavone B (6). All the isolates, except for compound 4, inhibited PTP1B activity <I>in vitro</I> with IC<SUB>50</SUB> values ranging from 5.3 to 42.6 μ<SMALL>M</SMALL>. This result further suggests that the prenyl group on the B ring of flavonoids plays an important role in suppressing the enzyme PTP1B.</P>
