PURPOSE: The purpose of this study was to evaluate Cardiopulmonary Resuscitation ability and level of knowledge among certain dental hygienists in Seoul and Gyeonggi-do. METHODS: We surveyed ability and knowledge of CPR among dental hygienists working at dental offices and dental hospitals located in Soul and Gyeonggi-do from September 18, 2010 to October 16, 2010. Data acquired from dental hygienists who had completed the questionnaire that we designed were used in the analysis. Uni- and bi-variate analysis and Chi-square test were performed using SAS 9.2. RESULTS: According to our findings, among respondents, approximately 14.29% of dental hygienists had a CPR license. Their CPR licenses are affected by working period, job position, and level of education (p<.05). Factors including working period, type of CPR license, and CPR license renewal were indicators of CPR knowledge level (p<.05). Significant differences were observed among dental hygienists with regard to subjective CPR abilities, which is dependent on obtaining a CPR license, CPR knowledge level, and education channel for CPR (p<.05). CONCLUSION: CPR ability and knowledge level among dental hygienists were not sufficient to save emergency people in the dental clinic. In order to save emergency patients patients, implementation of a CPR education and renewal program for dental hygienists is recommended.

Atopic dermatitis is a common chronic inflammatory skin disease, associated with marked inflammatory cells (of mast cells and eosinophils) and severe itching, which leads to clinical problems in the pediatric population. This study was designed to investigate the inhibitory effects of luteolin liposome solution, that is entrapped the hydrophobic luteolin (one of the flavonoids) into ethosome to improve its stability, by using hapten-induced atopic dermatitis animal model (NC/Nga mice).The luteolin liposome treated mice showed anti-inflammatory effect as evidenced by the lowering of erythema and edema in clinical observation, reduction of inflammatory cell infiltration and epidermal thickness in histopathological examination, when compared with TNCB induced controls. Luteolin liposome solution also reduced the serum IgE level which played important roles in the atopic dermatitis model. These results suggest that luteolin liposome solution has some merit in this formulation showing inhibitory effects for the atopic dermatitis.

Anatomy must be known not only by medical students but also by health science students. Furthermore, common people had better know anatomy because anatomy helps them keep their own health and dig up their own curiosity of body. It is desirable that common people learn morphology and function of the human body using easy, familiar, and interesting anatomy cartoon. But we could not find such a Korean anatomy cartoon, so that we tried to make anatomy cartoon for common people as follows. For anatomy cartoon, anatomist decided anatomy contents to write sentences. Based on the sententces, raw illustrations of anatomy cartoon were drawn on the paper with a pencil. Final illustrations of anatomy cartoon (931 cuts) were drawn on Adobe Illustrator of the personal computer. In addition, anatomy comic cartoon composed of four cuts (100 episodes) were drawn. Anatomy term explanations, anatomy photographs, and anatomy movies were created and hyperlinked with the anatomy cartoon, all of which were distributed through homepage (anatomy.co.kr), CD title, and book. The anatomy cartoon will be helpful not only to anatomy study of the common people and health science students but also to preliminary anatomy study of the medical students.

The review of normal intravenous pyelography can give us important criteria of the diseases of the urinary system and the adjacent organs. Authors analyzed 200 cases of intravenous pyelography of normal Korean adults and measured the following points; the length of kidneys, the distance from midline to both poles, the slope degree of longitudinal axis, the ureteral length and width, the shortest distance from midline to abdominal ureters, the longest distance form midline to pelvic ureters, and configuration of urinary bladder. The results were obtained as follows; 1. The average length of kidneys in adult male was 12.53±0.78 cm on right, 12.83±0.82cm on left; in adult female, 12.08±0.72cm on right, 12.46±0.73cm on left. In the age distribution, the length gradually became shorter by getting old. In 20% of cases, right kidney was longer than left. 2. The average distance from both the renal poles to midline was longer in male compared to female. The distance from upper pole to the midline was longer in left side than right in male, but in the lower pole, there was no difference in both sexes. 3. The slope degree of the renal longitudinal axis was larger in male than in female, and lager in right kidney compared to left. 4. The length of ureter was longer on left, but there was no remarkable difference between both sexes. 5.The short set distance from midline to abdominal ureter, there was no remarkable difference between both sexes and also between right and left side. But concerning the longest distance from midline to pelvic ureter, it was longer in female; and especially in female, right side was shorter than left. 6. The longitudinal diameter of urinary bladder was longer in male, but horizontal diameter was longer in female.

The present study assessed the effects of Rapid Maxillary Expansion on head posture and hyoid bone position. For this study, 32 Angle's class III patients - hellman 3c ~ adult stage, mean age 12y9m ? were selected divided into two group, A,B according to craniocervical angulation. Craniocervical angulation Increased in Group A and decreased in Group B after the therapy. And 23 Angle's class I persons ~ same hellman stage, mean age 12y7m ~ were selected for the control group. Cephalometric analysis of skeletal pattern, pharyngeal space, head posture, hyoid bone position was performed. The result were as follows, 1. Comparison of skeletal pattern and pharyngeal space 1) All two group(A,B) had Mandibular plane inclined inferiorly and no pharyngeal space change was observed after RME therapy. 2) Skeletal pattern and pharyngeal space of Group A, B were normal before and after treatment. 2. Comparison of head posture 1) Craniocervical angulation of Group A was increased after treatment. That of Group B was decreased and mandibular plane was inclined inferiorly after treatment. 2) Before treatment, craniocervical inclination was normal in Group A but larger than normal in Group B. After treatment, all two groups(A, B) had normal craniocervical angulation. 3. Comparison of hyoid bone position 1) After treatment, long axis of hyoid in Group A, B was not changed. Antero- posteriorly, hyoid position was changed posteriorly in Group A but no change was founded in Group B after treatment. Vertically, hyoid bone position were not changed in two group except increase in APHFH in Group A after treatment. 2) Long axis of hyoid bone was normal in Group A, B before and after treatment. Anteroposteriorly, hyoid bone position was more anterior than Group B, C before treatment but all the position of two groups had normal position after treatment. Vertical position of hyoid bone was normal in all two groups before and after treatment.

PURPOSE: Protein tyrosine kinase(PTK), protein kinase C(PKC), oxidase, as a mediator, have been known to take a role in signal transduction pathway of angiogenesis. The authors confirmed that PKC is the most noticeable mediator for abnormal proliferation of vascular endothelial cells through in vitro study model using the inhibitors, targeting the formation of three co-enzymes. In this study, we would investigate which isoform of PKC play an important role in abnormal angiogenesis of vascular endothelial cell. METHODS: In 96 well plates, 10(4) HUVECs(human umbilical vein endothelial cells) were evenly distributed. Two groups were established; the control group without administration of DMH(1,2-dimethylhydrazine) and the DMH group with administration of 7.5x10(-9)M DMH. RNA was extracted from vascular endothelial cell of each group and expression of the PKC isoform was analyzed by RT-PCR(reverse transcriptase-polymerase chain reaction) method. RESULTS: RT-PCR analysis showed that PKCalpha, -betaI, -betaII, -eta, -micron and -zeta were expressed in vascular endothelial cells of each group. DMH incresed the expression of PKCalpha and PKCmicron, and decreased PKCbetaI, PKCbetaII expression dominantly. CONCLUSION: Based on the result of this study, it was suggested that PKCalpha and PKCmicron may have significant role in abnormal proliferation of vascular endothelial cell.
