This study was conducted for the first time based on the evidence that cadaver practice is not easy in the university without medical school where cadaver dissection is not easy to look for. The purpose of this study was to evaluate the effect of osteology practice at human anatomy course for students at the freshman stage in college of health science without medical school. Both self report questionnaires and evaluation paper were analyzed depending on the course of higher education and gender. As a result of analysis, most students thought that osteology practice was interesting and it helped to understand of anatomy lecture. But students from liberal arts had poor understanding of bone's direction compared with students from natural sciences. And most students wanted to do cadaver dissectionafter osteology practice. In conclusion, osteology practice was recommended to student's expectation as well as education of gross anatomy in department of biomedical laboratory science, collage of health science without medical school. This study suggested that practice of gross anatomy should run parallel with lecture.

To enhance the in vitro permeation of lovastatin through excised hairless mouse and human cadaver skins, solubility was determined in various hydrophilic and lipophilic vehicles, and the effects of vehicles and penetration enhancers on the skin permeation from solution formulations were investigated. Solubility of lovastatin was highest in N-methyl-2-pyrrolidone (NMP) ($278.2{\pm}10.1$ mg/ml) and dimethyl sulfoxide (DMSO) ($162.2{\pm}9.7$ mg/ml). Among different pure vehicles used, NMP, DMSO, propylene glycol and isopropyl myristate provided some drug permeation ($6.9{\pm}1.1$, $5.9{\pm}1.6$, $3.0{\pm}0.5$ and $2.2{\pm}0.3{\mu}g/cm^2$ at 24 hr, respectively) through hairless mouse skin. The addition of oleic acid, linoleic acid and oleyl alcohol to DMSO showed the maximum permeation at around 5 v/v%, however, capric acid and caprylic acid had no enhancing effect. The increase of enhancer concentrations showed bell-shaped permeation rate, suggesting the presence of optimal concentration in lovastatin penetration. Increasing donor concentration from 10 mg/ml to 80 mg/ml in DMSO and a cosolvent of DMSO, NMP and DGME (3 : 3 : 4 v/v) did not show significant dose dependent permeation in both hairless mouse and human cadaver skins. The maximum lovastatin flux through human cadaver skin was found to be $0.87{\pm}0.46{\mu}g/cm^2$/hr with 5 v/v% linoleic acid and donor dose of 4 mg/0.64 $cm^2$ in the cosolvent. These results suggest that transdermal delivery of lovastatin would be feasible by establishing the optimal concentrations of donor dose and unsaturated fatty acids in appropriate vehicles.

In order to obtain optimum mixing conditions with animal cadaver residue and sawdust for composting using rendering treatment method for agricultural recycling, changes of chemical characteristics and compost quality after composting were investigated. Initial mixing ratios with animal cadaver residue and sawdust were adjusted 100 : 0, 50 : 50 and 30 : 70. Temperature, pH, contents of ammonia and carbon dioxide were rapidly increased in 3 days and then decreased with time. Organic matter content was similar in all conditions. In mixing ratio of 50 : 50, the compost quality was satisfied with compost depending on official standard for product fertilizer. Thus, the optimum mixing ratio of animal cadaver residue and sawdust were 50 : 50.

For medical students and doctors, knowledge of the three-dimensional (3D) structure of brain is very important in diagnosis and treatment of brain diseases. Two-dimensional (2D) tools (ex: anatomy book) or traditional 3D tools (ex: plastic model) are not sufficient to understand the complex structures of the brain. However, it is not always guaranteed to dissect the brain of cadaver when it is necessary. To overcome this problem, the virtual dissection programs of the brain have been developed. However, most programs include only 2D images that do not permit free dissection and free rotation. Many programs are made of radiographs that are not as realistic as sectioned cadaver because radiographs do not reveal true color and have limited resolution. It is also necessary to make the virtual dissection programs of each race and ethnic group. We attempted to make a virtual dissection program using a 3D image of the brain from a Korean cadaver. The purpose of this study is to present an educational tool for those interested in the anatomy of the brain. The procedures to make this program were as follows. A brain extracted from a 58-years old male Korean cadaver was embedded with gelatin solution, and serially sectioned into 1.4 mm-thickness using a meat slicer. 130 sectioned specimens were inputted to the computer using a scanner ($420\times456$ resolution, true color), and the 2D images were aligned on the alignment program composed using IDL language. Outlines of the brain components (cerebrum, cerebellum, brain stem, lentiform nucleus, caudate nucleus, thalamus, optic nerve, fornix, cerebral artery, and ventricle) were manually drawn from the 2D images on the CorelDRAW program. Multimedia data, including text and voice comments, were inputted to help the user to learn about the brain components. 3D images of the brain were reconstructed through the volume-based rendering of the 2D images. Using the 3D image of the brain as the main feature, virtual dissection program was composed using IDL language. Various dissection functions, such as dissecting 3D image of the brain at free angle to show its plane, presenting multimedia data of brain components, and rotating 3D image of the whole brain or selected brain components at free angle were established. This virtual dissection program is expected to become more advanced, and to be used widely through Internet or CD-title as an educational tool for medical students and doctors.

Purpose: It is to verify learning effect of the instructional media on anatomy classes at a nursing college and to develop an alternative instructional media instead of cadaver. Method: Four groups pretest-posttest experimental design were used. One hundred twenty students who attended an Anatomy lecture in September, 2009 were selected After attending the anatomy lecture, the subjects were divided into four group (30 for each group) conveniently. The heart anatomy knowledge level were measured by a self evaluation questionnaire and quiz before and after a different instructional media being applied for each group including making heart shape using colored clay, taking picture of a real heart, sketching the heart model with color pencil and drawing heart presented in the anatomy textbook. Data was analyzed by t-test, ANNOVA test using the SPSS/PC WIN 12 version. Result: A statistically significant differences in the level of heart anatomy knowledge acquirement was noted after four different instructional media being applied, and four different instructional media was effective to the anatomy practice education. However, no difference in statistical post test results was noted among the four groups. Conclusion: It is recommended that further comparative studies on the learning effect between human cadaver practice and different instructional media is necessary.

We present a case of angiographically confirmed transection of the cisternal segment of the anterior choroidal artery (AChA) associated with a severe head trauma in a 15-year old boy. The initial brain computed tomography scan revealed a diffuse subarachnoid hemorrhage (SAH) and pneumocephalus with multiple skull fractures. Subsequent cerebral angiography clearly demonstrated a complete transection of the AChA at its origin with a massive extravasation of contrast medium as a jet trajectory creating a plume. We speculate that severe blunt traumatic force stretched and tore the left AChA between the internal carotid artery and the optic tract. In a simulation of the patient's brain using a fresh-frozen male cadaver, the AChA is shown to be vulnerable to stretching injury as the ipsilateral optic tract is retracted. We conclude that the arterial injury like an AChA rupture should be considered in the differential diagnosis of severe traumatic SAH.

Axillary arch is relatively common variation of muscle in the axilla. There were several attentions on axillary arch due to its anatomical and surgical importance. During educational dissection, a variant muscle was found in right arm of 68-year-old female cadaver. The variation of muscle originated from the lateral edge of the latissimus dorsi muscle as muscular form. And then, it crossed the axillary artery and median nerve as tendinous form. Finally it became wide as muscular form and inserted into the pectoralis major. We reported this variant muscle and discussed its clinical significances.

Digastric and stylohyoid muscles are located in the suprahyoid region. There have been few studies about the general morphology of stylohyoid muscle and its relationship with digastric muscle. During routine educational dissection, unusual insertion of bilateral stylohyoid muscle was found in the cadaver of a 92-year-old Korean male, whose cause of death was 'aspiration pneumonia'. Stylohyoid muscle arose from the styloid process, and inserted onto the intermediate tendon of digastric muscle and the hyoid bone on both sides. Each digastric muscle normally consists of an anterior belly, intermediate tendon and a posterior belly. In this cadaver, there were two anterior bellies on right side while one anterior belly was found on left side. Stylohyoid muscle ran medial to the intermediate tendon of digastric muscle on both sides. The anatomical relationship between stylohyoid and digastric muscles was reviewed based on morphological and embryological point of view.
