Purpose: We wanted to evaluate the clinical and radiologic results of acetabular revision using the acetabular reinforcement ring and also the allograft impaction in the acetabulum having deficient bone stock. Material and Methods: Nineteen hips revision arthroplasty were performed in 18 patients (9 males and 9 females) with using an acetabular reinforcement ring and allograft between July 1993 and December 2003. The patients were followed for an average of 64 months (range: 24-153). The mean age at the time of arthroplasty was 59 years old (range: 34-76). The causes of revision were aseptic loosening of the acetabular component in 16 cases, severe progressive osteolysis around the acetabular component in 2 cases and Girdlestone state after infected total hip arthroplasty in one case. The acetabular deficiency was type II in 5 hips, type III in 13 hips, and type IV in one hip according to the AAOS classification. The clinical results were evaluated using the modified Harris hip score, and the radiologic results were evaluated by assessing the preoperative and serial follow-up radiographs. Results: The mean preoperative Harris hip score of 47 was improved to 86 points at the latest follow-up. Periacetabular osteolysis was found in 2 cases, which did not progress at follow-up. The anatomic hip center was restored after revision arthroplasty (p<0.05). Complications were dislocation in 2 cases, breakage of the hook of the Ganz ring in one case, heterotopic ossification in one case and femoral artery injury in one case. All cases showed stable fixation of the acetabular component and good remodelling of the impacted allograft. There was neither recurrence of dislocation nor progression of the acetabular component loosening on the radiographs. Conclusion: Acetabular revision with acetabular reinforcement ring and allograft impaction showed satisfactory clinical and radiologic results with restoration of the hip center and consolidation of the allograft.

BACKGROUND: The purpose of this study is to evaluate what kind of crystalloid solution could function as the best buffer and correct the metabolic acidosis most effectively in rabbits with hemorrhagic shock. METHODS: Twenty eight rabbits were bled until mean arterial pressure(MAP) became 70% of control. Thirty minutes after hemorrhagic shock fluid resuscitation was started with either plasmalyte or Hartmann's solution or 0.9% normal saline until MAP returned to 90% of the control. Hemodynamic and blood gas study, plasma lactate and electrolyte concentration were measured before, during, and 30 minutes after recovery from shock. RESULTS: The amount of shed blood to reduce MAP to 70% of control ranged 76~87 ml. And the volume for fluid resuscitation was 274~324 ml. There was no statistically significant difference among the three groups. The pH decreased during shock in all group and still decreased after resuscitation in Hartmann's solution and normal saline. But it increased significantly after resuscitation in plasmalyte. Lactate was increased in all group during shock and decreased by 22 and 23 mg/dl after resuscitation in plasmalyte and normal saline. But it still increased by 40 mg/dl in Hartmann's solution. Serum potassium level decreased significantly after resuscitation with normal saline. Serum calcium level decreased significantly after resuscitation with plasmalyte and normal saline. CONCLUSION: With the above results the plasmalyte which has pH closer to that of normal blood might be able to avoid the metabolic acidosis and maintain acid-base equilibrium effectively after fluid resuscitation in acute hemorrhagic shock.

Clinical application on composite resin recently draw great concerns in dentistry. Especially due to advantages such as esthetics, adhesiveness, simple clinical procedures, various shapes and kinds of composite resin are widely being applied to prosthodontics, conservative dentistry, and orthodontics. But, clinical problems attributable to the polymerization shrin-kage of composite resin have been proposed, and we have to regard clinical problems such as secondary caries, loss of restoration, fracture of the surrounding tooth structure, marginal discoloration, and tooth sensitivity, and many portions are remained to be over-come. Therefore, this study attempts to analyze stress distribution between resin and tooth structure which is generated during polymerization shrinkage of composite resin using three dimensional finite element method. Three dimensional finite element models with conventional box-shape cavity and ero-sion/abrasion type V-shape lesion cavity in upper central incisor were developed. These cavities were filled with four different types of placement techniques. (bulk filling, horizontal increment filling, oblique occlusal increment filling, oblique gingival increment filling) The stresses generated by polymerization shrinkage of composite resin were calculated. The results analyzed with three dimensional finite element method were as follows : 1. The increment filling technique showed the highest maximum normal stress in both conventional box-shape and V-shape cavities and showed a tendency to decrease after complete polymerization. 2. The bulk filling technique resulted in increased stresses during the curing process in both conventional box-shape and V-shape cavities and the highest maximum normal stress occurred after complete polymerization. 3. The bulk filling resulted in the lowest maximum normal stress in both box-shape and V-shape cavities 4. Regardless of placement method, in conventional box-shape cavity, the maximum normal stress increased in dentin floor, enamel, dentin sequence and in V-shape cavity, the maximum normal stress increased in enamel, dentin sequence.

Eccrine poroma, first described in 1956 by Pinkus, is a fairy common benign skin appendage tumor arising from the poral epitheliurr of the eccrine sweat gland in most regions of the body surface, hairy or nonhairy. generally in persons past the age of 40. The tumor is almost always single, but cases of eccrine poromatosis have been described and is a firm, sometimes lobulated nodule which may be sessile or slight pedunculated. There is often a vascular appearance, and the clinical appearance may suggest pyogenic granuloma. Microscopically, the tumor mass extends from the epidermis downward into the dermis as broad, anastomosing bands. Tumor cells are small, uniform, cuboidal appearance containing round, deeply basophilic nucleus and are connected by intercellular bridges. PAS stain-positive glycogen which diisappears with diastase are irregularly scattered in the tumor cells. A caee of unusual variant of eccrine poroma is reported. 25-year-old male patient has a finger tip sized crusting pedunculated lesion for approximated 12 months on the right postauricular area. The diagnosis was confirmed by clinical and histopathological findings as eccrine poroma and surgical excision was done.

Telomerase is an enzyme that maintains telomeres and prevents telomere shortening, and may be linked with cellular proliferation or the aging process. The purpose was to examine telomerase activity in human chorionic villi from early and term normal pregnancies, and to analyze the correlation of telomerase activity (TA) with MIB-1 & bcl-2. A total of 37 placentae were obtained from 16 early and 21 term pregnancies. TA was assayed by telomeric repeat amplification protocol, and immunohistochemical staining was performed for MIB-1 & bcl-2 expression. TA & MIB-1 expression were strong in early placenta, but bcl-2 was highly expressed in term placentae. Thirteen (81.25%) of 16 early placentae showed TA, but only 2 (9.52%) of 21 term placentae expressed TA (p<0.01). MIB-1 was observed in nuclei of cytotrophoblast, and the expression rate was 16.09% in early placentae and 2.87% in term placentae (p<0.01). bcl-2 was observed only in the cytoplasm of syncytiotrophoblast. Term placenta demonstrated stronger expression of bcl-2 compared to early placentae (p<0.05). These findings suggest that TA, MIB-1 & bcl-2 expression are critically regulated over the course of gestation: cytotrophoblast, main cells of early chorionic villi, may be a common source of telomerase and proliferative activity. The TA showed good correlation with cellular proliferative activity. Syncytiotrophoblast, may be a main source of bcl-2 expression which is stronger in the term placentae.

BACKGROUND: Baroreceptor reflex responds to the decrease in blood pressure caused by drug, dehydration, or severe bleeding. Vagal reflex caused by direct pressure on vagus nerve, the traction, or lung inflation develops bradycardia and severe arrhythmia. Lung inflation elicits a vasodepressor reflex, resulting in stimulation of the vagus nerve which causes a decrease in sympathetic outflow. METHODS: 75 patients who had elective surgery were divided into 3 groups according to the age, such as group I: < or =15 years of age, group II: 16-64 years of age, group III: > or = 65 years of age. Lung inflation test has been performed at 20 cmH2O for 20 seconds. Baroreceptor was stimulated by lowering blood pressure with intravenous infusions of nitroglycerin. Baroreceptor sensitivity was assessed by measuring the decrease in blood pressure. Vagal reflex sensitivity was calculated by the subtraction of G2 (baroreceptor reflex sensitivity after introglycerin infusion) from G1 (heart rate response to lung inflation). RESULTS: Baroreceptor reflex induced by hypotension and vagal reflex originated from lung influe-nced the heart rate inversely when lung inflated. Baroreceptor reflex sensitivity was highest in younger patients and lowest in older patients when nitroglycerin infused. Vagal reflex sensitivity was highest in older patients and lowest in younger patients. CONCLUSIONS: Baroreceptor reflex was most sensitive in younger patients, but vagal reflex was moresensitive in older patients.

Purpose: Genu valgum in Legg-Calve-Perthes disease (LCPD) is not a known complication. We investigated whether this valgus tendency is a complication of femoral varus osteotomy (FVO) or the sequela of the disease process itself, and what are the related factors. Materials and Methods: 35 patients treated by FVO and 38 by abduction orthosis (AO) were selected for this study. Only those patients with unilateral involvement, fragmentation stage, Catterall Group III or IV, and who were followed-up to full skeletal maturity were included in the study. We measured mechanical axis deviation percentage and hip-knee-ankle angle for femorotibial alignment, and mechanical lateral distal femoral angle and medial proximal tibial angle (mMPTA) for knee orientation on teleoroentgenograms and compared the affected and normal limbs. Results: All measurements, excluding the mMPTA, demonstrated a tendency of relative genu valgum versus the opposite normal limbs. This tendency was observed in both groups. There was no statistically significant difference between the two groups. Conclusion: Genu valgum occurred in 66% to 70% of the LCPD patients. Four factors were found to be significantly correlated with valgus shift: increased medial bowing of the femoral neck, decreased acetabulum head index, coxa magna, and limb shortening. Multivariate regression analysis identified limb shortening as the factor most responsible for valgus shift.
