4.Bilateral cleft lip nose deformity correction withouter table calvarial bone graft and suspension suture method.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 1998;25(6):1017-1025
The purpose of this study is to introduce the patients with bilateral cleft lip nose have lots of distinctive anatomical features such as short columella, inferior displacement of the medial crura of alar cartilage, lowering of the alar dome, flattened tip of the nose, widened nostril sill and prominent vestibular skin web. Although millard, Kaplan and Wray have introduced columellar lengthening by fork flap, it was difficult to achieve satisfying results without reconstructing the nasal skeletal framework of the cleft lip nose deformity for their anatomical distinctiveness. We have performed rhinoplasty on 7 patients with bilateral cleft lip nose from January. 1995 to August. 1997, using onlay calvarial bone graft and suture suspension technique. Operation was performed on basic anatomical structure, skeletal framework using outer table of calvarial bone pushed into the nasal tip area and suspension suture was applied to the framework with anteroinferior projection of nasal tip projection vector by cantilever effect of the calvarial bone which carried out nearly normal anatomical nasal structure. We have obtained satisfying results without complication in all seven cases. In conclusion the method which authors have used shows several advantages. First, it was possible to obtain the substantial skin lengthening in anterior and inferior direction by "Tent-Pole effect" in which creating bony structure projected into nasal tip and traction suturing of the deformed alar cartilages. Secondly, columellar lengthening and close to normal nostril shape was obtained and thirdly, re-deformation of corrected structure was prevented. An expected problem in above method is resorption of grafted calvarial bone which expected to maintain its position under influence of alternation and reformation by reaction between chondroblast and chondroclast results in fibrous tissue replacement, yet long term follow up is necessary for futher evaluation.

As an attempt to evaluate any possible effects of dimethylsulfoxide (DMSO) on the phenomena of membrane transport, effects on the short-circuit current (SCC) and potential difference (PD) across the isolated frog skin were studied under the conditions of various bathing medium, Changes of SCC and PD were measured by the method described by Ussing and Zerahn. Addition of DMSO to the inside bathing medium resulted in an initial increase in SCC followed by a secondary decline to pre-DMSO level, while DMSO at outside medium was without effect. Dose-responses(SCC) relationship revealed a linear one from 30 to 60 mM. Substitution of chloride by sulfate ion from bathing medium caused no alteration in the basic pattern and magnitude of response, thus indicating the specificity of DMSO action on the Na transport. Hypertonic solutions of DMSO added to either outer or inner bathing medium evoked a prompt fall in SCC and PD consistently. By isotopic measurement of sodium fluxes with Na24, it was evident that increased sodium influx was entirely responsible for the initial increase in SCC induced by DMSO. Of various parameters concerned with transepithelial Na transport, outer membrane permeability to Na (PoNa) was shown to be the onIy parameter which was significantly elevated by DMSO administration. From these findings, it was postulated that DMSO-induced increment in sodium influx was mediated by its stimulating action on the sodium penctration through the outer permeability barricr after binding to a receptor site different from that for the antidiuretic hormone (ADH.)

10.Use of Behavioral Analysis in Animal Models for Schizophrenia Research.

Animal models are useful tools to study the molecular basis of schizophrenia pathophysiology and efficacy of potential therapeutic agents. Schizophrenia animal models can be subdivided into three classes ; drug-induced models, genetic models, and environmental models and each model is designed based on specific traits corresponding to the characteristic symptoms of human schizophrenia patients. Psychomotor agitation and sensitivity to psychotomimetic drugs are often thought to reflect positive symptoms. Social interaction deficits and affective impairments are known to correspond to negative symptoms. Also, cognitive symptoms have been linked to the working memory impairments, attention deficits and related cognitive deficits in animals. To analyze such components in quantifiable manners, various behavioral paradigms have been developed and utilized. Here, we overview these animal models, focusing on underlying rationales for their use in the context of schizophrenia research.
