  • Some patients with type 1 and type 2 diabetes mellitus (DM) present with cognitive dysfunctions. The pathophysiology underlying this complication is not well understood. Type 1 DM has been associated with a decrease in the speed of information processing, psychomotor efficiency, attention, mental flexibility, and visual perception. Longitudinal epidemiological studies of type 1 DM have indicated that chronic hyperglycemia and microvascular disease, rather than repeated severe hypoglycemia, are associated with the pathogenesis of DM-related cognitive dysfunction. However, severe hypoglycemic episodes may contribute to cognitive dysfunction in high-risk patients with DM. Type 2 DM has been associated with memory deficits, decreased psychomotor speed, and reduced frontal lobe/executive function. In type 2 DM, chronic hyperglycemia, long duration of DM, presence of vascular risk factors (e.g., hypertension and obesity), and microvascular and macrovascular complications are associated with the increased risk of developing cognitive dysfunction. The pathophysiology of cognitive dysfunction in individuals with DM include the following: (1) role of hyperglycemia, (2) role of vascular disease, (3) role of hypoglycemia, and (4) role of insulin resistance and amyloid. Recently, some investigators have proposed that type 3 DM is correlated to sporadic Alzheimer's disease. The molecular and biochemical consequences of insulin and insulin-like growth factor resistance in the brain compromise neuronal survival, energy production, gene expression, plasticity, and white matter integrity. If patients claim that their performance is worsening or if they ask about the effects of DM on functioning, screening and assessment are recommended.

  • Human cervical spine has to protect the neural components and vascular structures. Also, it must have the flexibility afforded by an extensive range of motion to integrate the head with the body and environment. Because of these two-sided features, human cervical spine has very complicated shapes and their injury mechanisms are not fully understood yet. We have developed analytical model of human CS by using the finite element method. The model has been verified with in vivo and in vitro experimental results. From the qualitative analysis of simulation results, we were able to explain some of the fundamental mechanisms of neck pain. Further more, this FE model of human CS can be used as an analytical tool or biomechanical design of the clinical device and safety restraints.

  • In breast reconstruction with a free flap following mastectomy, the recipient vessels most widely used are in the axillary system, which limits flap movement and flexibility in breast shaping. In addition, scarring and fibrosis can make dissection of the vessels difficult. We have performed 43 breast reconstructions using a free transverse rectus abdominis myocutaneous(TRAM) flap. In 10 cases out of 20 delayed reconstruction, we anastomosed to the internal mammary vessels rather than subscapular system. There has been no flap failure. The surgical techniques, advantages and limitations of the internal mammary system are presented. The internal mammary vessel are compared with the axillary vessels as a recipient vascular system.

  • The purpose of the present study is to investigate the effects of long-term exercise program on exercise capacity and cognitive function (MMSE) in male patients with dementia. 24 male patients were divided into two experimental groups : the exercise group (n=12) and the control group (n=12). The exercise group participated in regular exercise program for 12 months, and their exercise capacity (cardiopulmonary function, muscle strength, muscular endurance, flexibility, balance, agility) and MMSE (Mini-mental state examination) levels were evaluated at baseline (pre), after 6 months (mid) and after 12 months (post). The subjects carried on group-exercise of $VO_{2}max\;30\~60\%$, $30\~60$ minute a day, $2\~3$ times per week. Statistical techniques for data analysis was paired samples t-test. The level of statistical significance was ${\le}.05.$ The results of this study were summarized as follows: In the exercise group, there were significant differences in cardiopulmonary function, muscle strength, muscular endurance and MMSE at the times of pre & mid and pre & post, there were significant differences in balance and agility at the time of pre & post only, whereas there was no significant difference in flexibility following the long-term exercise. In the control group, there were no significant differences in all the times. Based on the results of this particular study, one year exercise program increases on the cognitive function & exercise capacity in male patients with dementia.

  • The preparation of PVA/Chitosan/Fibroin (PCF)-blended sponge sheets and wound healing effects of these sheets in rats were investigated. We excised the skin off rat, including the dermis, approximately 2${\times}$2 cm in size. The wound was coveted with PCF-blended spongy sheets. The spongy sheets absorbed the exudate, and gained flexibility and softness. Histopathological inspection of the wound 12 days later showed the increase of a vascular ingrowth and the absence of inflammatory cells. Regeneration of the skin around the wound was faster than that of the control. We also tested wound healing effects of PVA, Chitosan and Fibroini alone of in various combinations. Wound healing was accelerated in the order of PVA/chitosan/Fibroin (PCF)-blended sponge>Chitosan/Fibroin (CF)-blended sponge$\geq$Fibroin (F) sponge>PVA/Chitosan-blended sponge (PC)>Chitosan (C) sponge.

  • Although drug-eluting stents have reduced the problem of restenosis, such stents exhibit side effects such as inhibition of reendothelialization and inflammatory reactions due to persistent drug reactions and sensitivity of polymers. To solve this problem, suppressing the continuous drug reaction by controlling drug release behavior induce rapid vascular re-endothelization. In this study, we attempted to control drug release from a paclitaxel- and cilostazol-containing stent using ethylene vinyl alcohol (EVOH). We then used a scanning electron microscope and atomic force microscope to observe changes on the surface of the drug-releasing stent following the inclusion of EVOH in comparison with stent without EVOH. There were almost no differences on the surface of the drug-eluting stent due to EVOH. The drug release was initially higher in the EVOH-containing stent compared to the stent without EVOH, and the degradation behavior of the polymer not affected by addition of EVOH. Cytotoxicity of the stent containing EVOH was evaluated. EVOH did not exhibit any cytotoxicity due to the degree of controlled release of the drug. Additionally, mechanical property of stent was confirmed by using EVOH and cellulose acetate butyrate (CAB). Radial force increased in stent with EVOH compared to without EVOH although flexibility was not changed. These results suggest that the application of EVOH to drug-eluting stents does not affect the degradation behavior of the stent surface and polymer, but it could be expected to suppress the sustained and excessive response of the drug by rapid release of the drug.

  • Diagnosis and treatment of the unstable shoulder is one of the more difficult problems in orthopaedic surgery. There is confusion between the normal laxity with translation and subluxation of the humeral head relative to the glenoid and an abnormal amount of laxity, leading to pain and dysfunction. Unfortunately, there is no single treatment that applied to all lesions that cause the instability. It is imperative, therefore, that an accurate diagnosis be made, including the directions and degree of shoulder instability as well as any coexisting problems. Anatomical defects must be defined. Common factors that could most readily compromised instability repair are examined. These include techniques for making an accurate diagnosis with identification of the precise anatomical pathology, and the rationale for appropriate surgical treatment with the avoidance of technical complication such as unnecessary hardware or exposures that might lead to residual instability, arthritis, and nerve or vascular injuries. Additional injuries may be prevented by careful rehabilitation postoperatively to restore shoulder stability, flexibility, and endurance prior to an individual's return to stressful sports or work.
