Hypoplasia of the internal carotid artery is a rare congenital anomaly. Agenesis, aplasia, and hypoplasia of the internal carotid artery [ICA] are frequently associated with cerebral aneurysms in the circle of Willis. Authors report two cases with congenital hypoplasia of the ICA accompanying with the aneurysms. Transfemoral cerebral angiography [TFCA] in one patient identified nonvisualization of the left ICA. Bilateral anterior cerebral artery [ACA] and middle cerebral artery [MCA] were supplied from the right ICA accompanying with two aneurysms at anterior communicating artery [AcoA] and A1 portion of the left ACA. TFCA in another patient demonstrated hypoplastic left ICA and left ACA filled from the right ICA accompanying with AcoA aneurysm. Left MCA was filled from basilar artery via posterior communicating artery [PcoA]. Skull base computed tomography [CT] in two patients showed hypoplastic carotid canal. Authors performed direct aneurysmal neck clipping. Follow up CT angiography [CTA] at one year after surgery did not show regrowth or new development of the aneurysm. In patients with hypoplastic ICA, neurosurgeons should be aware of the possibility of development of the aneurysms, presumably because of hemodynamic process. Direct aneurysmal neck clipping is a good treatment modality. After operation, regular CTA, magnetic resonance angiography [MRA] or TFCA is needed to find progressive lesion and to prevent cerebrovascular attack [CVA].

Pressure sores are an ulceration and necrosis of the skin and underlying tissue usually occur after prolonged or repeated pressure by interruption of blood flow from the small. vessels to the skin and deep tissue. The management of pressure sores is mostly difficult and requires prolonged hospitalization or repeated surgical interventions with a high recurrence rate. In this article we reviewed 14 cases of National Pressure Ulcer Advisory Pannel staging III, IV over the lateral malleolar area of the ankle in 2 years period from January 1999 to October 2001. The pressure over lateral malleolar area was mainly due to unique Korean sitting position with cross legs at flexed hips and knees or supine position of patient with external rotation of low extremity. Male to female ratio was 11: 3 and ages were between 36 and 83 (mean age: 67.1 years). Associated diseases were DM(7 cases), Hemiparesis caused by CVA(2 cases), Liver cirrhosis(2 cases), disarticulation of opposite hip due to squamous cell ca.(1 case), Intertrochanteric Fx.(1 case). Wound cultures reported Staphylococus, Pseudomonas and others. Abnormally elevated ESR and CRP were seen in 6 cases. Operative treatments were irrigation and debridement, direct closure with gravity drainage and skin grafting. The most important aspect of pressure sore treatment is pressure relief of the lateral malleolar area. Pressure-relieving Cast or Brace was helpful for local management and preventing recurrence.

Background: The purpose of this case study was to investigate into the effect of complex exercise program on the postural change, gait and balance ability in elementary school students with forward head posture. Methods: Four patients with forward head posture were recruited. They were evaluated pre-treatment, and after 6weeks, using neck disability index (NDI), numeric pain rating scale (NPRS), balance ability, foot pressure (fore foot/rear foot peak pressure ratio, F/R ratio), gait ability (cadence, toe out angle, stance phase). Results: First, the angle of forward head posture (craniovertebral angle; CVA and cranialrotation angle; CRA) was decreased in all subjects. The NPRS and NDI were decreased in all subjects. Also, The cadence, toe out angle and F/R ratio were increased in all subjects. The stance phase of gait cycle was positively change in all subjects. Lastly, the static balance ability improved in all subjects. Conclusion: According to the results above, the complex exercise program for students with forward head posture can help improve the postural change, gait and balance ability. Also, the complex exercise program was able to select interventions depending on the patient's condition and the desired goal.

The purpose of this study was to investigate the variations in gait parameters according to arm slings used in healthy adults. Twenty healthy adults (9 males, 11 females) participated in this study and walked at self-selected speeds on a GAITRite-instrumented carpet. They were randomly assigned conditions: without an arm sling, a care sling, a Harris hemi arm sling, a CVA sling, and a Rolyan humeral cuff sling. The following gait parameters were analyzed: the temporo-spatial parameters of gait velocity, swing phase, single support, cadence. In the comparison of parameters in each trial, step length was statistically significantly changed(p=.002). The right step length was significantly decreased in the Harris hemi arm sling and increased in the Rolyan humeral cuff sling when compared with no sling. This study found that several different types arm slings varied gait pattern in healthy adults.

Yangkyuksanhoa-tang is frequently used for cerebrovascular accident(CVA). The present study was performed to investigate the effect of Yangkyuksanhoa-tang on the peri vascular immunoreactive nerve fiber of the basilar artery after experimentally induced subarachnoid hemorrhage(SAH). Sprague Dawley rats weighing between 350-400g were used. The SAH induced by injection of the fresh autologus heart blood(0.3-0.4ml) into the cisterna magna through the posterior atlanto-occipital membrane. Sample group was given a $3.3m{\ell}/kg/day$ of Yangkyuksanhoa-tang extracts for 2 days after SAH. The experimental animals divided into 48hrs after SAH. The changes of perivascular immunoreactive nerve fiber was examined by using indirect immunofluorescence method. The meshlike perivascular nerve fiber appeared in the basilar artery of normal rats. In basilar artery of SAH elicitated rat, the distribution of calcitonin gene-related peptide (CGRP)-immunoreactivity(IR) and vasoactive intestinal polypeptide(VIP)-IR of the perivascular nerve fiber were remarkably diminished, also dopamine beta hydroxylase(DBH)-IR, neuropeptide Y(NPY)-IR and serotonin-IR were diminished. In SAH elicitated rat with Yangkyuksanhoa-tang treatment, the CGRP-IR and VIP-IR degree were repaired as well as normal rat's, but DBH-IR, NPY-IR and serotonin-IR had no changes. These results provide the basic data to investigate the effect of Yangkyuksanhoa-tang on the vasospasm after SAH.

For the development of drugs for alzheimer,s disease, the study was done to review the oriental pathology, clinical data, recent trends for research and strategy for future study. The results were as follows: 1. The medical term Chi-dsi implying alzheimer,s disease was referred for the first time in a medical book, Hwatasheneubijeon written by Hwa-Ta and its differentiation and treatment were studied more in Ming or Ching dynasties. Chi-dai can be differentated as weak(虛) syndrome and Shi(實) syndrome. This can be caused by deficiencies of renal Yin, renal Yang, cardiac Yin and hepatic blood, while that by deficiencies of pathological fluid(痰飮) and clotted blood(瘀血). 2. Dementia can be roughly classified as alzheimer's disease and multi-infarct disease. Its causes were known to be cholinergic transmitter, C-peptide, amyloid-${\beta}$, apolipoprotein, APP(amyloid precursor protein), TGF, MMP-9 and free radical. 3. In Korea experimental studies were chiefly done for the elimataion of C-peptide, amyloid-${\beta}$, apolipoprotein, APP for alzheimer's disease, for the development of drug inhibiting degerative change following CVA and loss of memory and also administrative measure was done by support of government. 4. Drugs of dimentia developed so far were Chi-Dai dan, extracts from aloe, mushroom, green tea, Ganoderma and also folic acid, vitamin C, DHEA and silk amino acid were reported to be effective in dimenta. 5. Future strategic research had better be done on dementia-inducing factors such as acetylcholine, C-peptide, amyloid-${\beta}$, apolipoprotein, APP, TGF, MMP-9 and free radical, development of animal model for dimentia, clinical study, epidemiology, nursing and administrative studies and also consortium for dimentia research should be formed so that repeated investment be avoided.

This study was conducted to investigate the use of medical equipment in patients receiving home care service. The subjects of this study were 88 patients cared by seven home care nursed who were registered in the Seoul Nurses Association. Data was collected from Aug. 1, 1998 to Dec. 30, 1998. The findings are as follows. 1. The sample was found to be 55.7% female : 51.7% over 65 years old. 75% with neurologic disease including CVA, brain tumor, ICH, Parkinsonism & Spinal stenosis and 78.4% living in Seoul. The Clinical experience of the home care nurses was greater than five years. 2. Medical equipment which the patients possessed were foley catheters(61.4%), L-tubes(59.1%) and tracheostomy tubes(51.1%). 3. Technical difficulties in use of medical equipment were related to home care ventilators(60.0%), L-tubes(3.8%) and tracheostomy tubes(2.2%). 4. Most of the medical equipment were obtained from the hospital where they had been admitted previously or from medical equipment companies. 5. Complications from the use of this equipment were infection through invasive techniques including wound drainage tubes(50%), and IV injections(22.2%), The complications were resolved through referral to the doctor of the hospital where they were previously admitted or through community health centers. 6. Most of the equipment was disposable, and equipment was disinfected by using various methods including boiling and soaking in antiseptic solutions. These findings suggest that consistant policy on the management of medical equipment is necessary for the safety of home care patients.

Since the importance of teacher knowledge in teaching mathematics has been emphasized, there have been many studies exploring the nature or characteristics of such knowledge. However, there has been lack of research on the tools of investigating teacher knowledge. Given this background, this study explored teachers' knowledge of fraction lessons using classroom video analysis. The analyses of this study showed that knowledge of teaching methods was activated better than that of student thinking or mathematical content. Knowledge of fraction operation was activated better than that of fraction concept. The degree by which teacher knowledge was activated depended on the characteristics of the video clips used in the study. This paper raised some issues about teachers' knowledge of fraction lessons and suggested classroom video analysis as an alternative tool to measure teacher knowledge in the Korean context.
