Purpose: The purpose of this study was to clarify the panoramic image differences of cleft alveolus patients with or without a cleft palate, with emphases on the visibility of the line formed by the junction between the nasal septum and nasal floor (the upper line) and the appearances of the maxillary lateral incisor. Materials and Methods: Panoramic radiographs of 238 patients with cleft alveolus were analyzed for the visibility of the upper line, including clear, obscure or invisible, and the appearances of the maxillary lateral incisor, regarding congenital absence, incomplete growth, delayed eruption and medial inclination. Differences in the distribution ratio of these visibility and appearances were verified between the patients with and without a cleft palate using the chi- square test. Results: There was a significant difference in the visibility distribution of the upper line between the patients with and without a cleft palate (p<0.05). In most of the patients with a cleft palate, the upper line was not observed. In the unilateral cleft alveolus patients, the medial inclination of the maxillary lateral incisor was more frequently observed in patients with a cleft palate than in patients without a cleft palate. Conclusion: Two differences were identified in panoramic appearances. The first was the disappearance (invisible appearance) of the upper line in patients with a cleft palate, and the second was a change in the medial inclination on the affected side maxillary lateral incisor in unilateral cleft alveolus patients with a cleft palate.

Review : Prostaglandin D2 and TH2 Inflammation in the Pathogenesis of Bronchial Asthma
( Masafumi Arima ),( Takeshi Fukuda ) 대한내과학회 2011 The Korean Journal of Internal Medicine Vol.26 No.1
Prostaglandin D2 (PGD2) is a major prostanoid, produced mainly by mast cells, in allergic diseases, including bronchial asthma. PGD2-induced vasodilatation and increased permeability are well-known classical effects that may be involved in allergic inflammation. Recently, novel functions of PGD2 have been identified. To date, D prostanoid receptor (DP) and chemoattractant receptor homologous molecule expressed on T(H)2 cells (CRT(H)2) have been shown to be major PGD2-related receptors. These two receptors have pivotal roles mediating allergic diseases by regulating the functions of various cell types, such as T(H)2 cells, eosinophils, basophils, mast cells, dendritic cells, and epithelial cells. This review will focus on the current understanding of the roles of PGD2 and its metabolites in T(H)2 inflammation and the pathogenesis of bronchial asthma. (Korean J Intern Med 2011;26:8-18)

<P><B>ABSTRACT</B></P><P><I>Cryptosporidium andersoni</I> and <I>Cryptosporidium muris</I> infections have been found in the mice and/or cattle. The oocysts of <I>C. andersoni</I> and <I>C. muris</I> have been sporadically detected in human feces, but the infectious capacity and features have been unknown, because of the scarcity of reports involving human infections. To assess the infectivity and the clinical and pathological features of <I>C. andersoni</I> and <I>C. muris</I> in primates, an experimental infectious study was conducted using cynomolgus monkeys. The monkeys were orally inoculated with oocysts of two different <I>C. andersoni</I> Kawatabi types and <I>C. muris</I> RN-66 under normal and immunosuppressive conditions. The feces of the monkeys were monitored for about 40 days after the administration of oocysts using the flotation method, but no shedding oocysts were observed under either both normal or immunosuppressive conditions. Gross and histopathological examinations were performed on the immunosuppressive monkeys, but these revealed no evidence of <I>Cryptosporidium</I> infections, even though the monkeys were subjected to immunosuppressive conditions. It is hypothesized that <I>C. andersoni</I> and <I>C. muris</I> pose little danger of infection in primates even under immunosuppressive conditions.</P>
