From Feb. 1996 to Feb. 1997. among sixty-four patients of anterior cruciate ligament(ACL) reconstruction using multi-stranded hamstring tendon and EndoButton fixation, twenty-five patients of volunteer, 15 men and 10 women, from 16 to 50 years of age(mean 27.6 years) underwent arthroscopic evaluation. Arthroscopic evaluation was routinely performed one year after surgery along with an examination of stability. The purpose of this study was to arthroscopically evaluate the morphological changes that occurred in hamstring tendon autograft one year after ACL reconstruction. Both of the tendon graft and the adjacent fibrous tissues were observed for gross appearance and physical properties with probing and response to passive anterior translation. Biopsy samples were taken from the surrounding fibrous tissue and the tendon graft. Grossly, we found a well-defined ligamentous structure with good tension tested with a probe. A common finding was that the reconstructed ligaments were embedded in a layer of the synovium, and blood vessels could be seen on the anterior surface of the ligament. The biopsy tissue was placed in formalin solution and subjected to histological preparation by hematoxylin and eosin staining method. The hamstring tendon graft appeared histologically normal under light microscopic finding. There were a few vessels located between existing collagen bundles, and the vessels had an orderly pattern. The surrounding fibrous tissue envelope was covered with synovium. We pleased with preliminary findings in our evaluation.

Single oral administration to SD rats of both sexes were performed to investigate the acute toxicity of two new cough and cold remedies, WHS-1 and WHS-2. WHS-1 is composed of acetaminophen, chlorpheniramine maleate, cloperastine hydrochloride, dl-methylephedrine hydrochloride, caffein anhydrous, thiamine hydrochloride, riboflavin and serratiopeptidase. WHS-2 is composed of similar formula except that thiamine hydrochloride and riboflavin is not added. The results were as follows. $LD_{50}$ values of WHS-1 were 4295.5 mg/kg for males and 4606.3 mg/kg for females, and $LD_{50}$ values of WHS-2 were 3236.7 mg/kg for males and 4360.5 mg/kg for females. Death occurred within 2~3 hours after administration at doses up to 2900 mg/kg in WHS-1 and 2500 mg/kg in WHS-2, the main cause of deaths seemed to be respiratory disturbance. General symptoms included decreased motor activity, salivation and loss of consciousness which were commonly observed in all dead animals treated with WHS-1 and WHS-2. No significant gross finding and body weight changes were observed at any dose level in the groups treated with WHS-1 and WHS-2.

PURPOSE: The aim of this study was to evaluate activation of accessory respiratory muscles using electromyography during chest expansion upper extremity flexion, abduction, and external rotation exercises with an elastic band in children with cerebral palsy. METHODS: The subjects were 10 children with cerebral palsy. The inclusion criterion for participation was a Gross Motor Function Classification System level of I to III. The subjects were instructed to perform upper extremity flexion, abduction, and external rotation exercises with inspiration, and extension, adduction, and internal rotation exercises with expiration while seated on a chair without a backrest. PM (Pectoralis major), SCM (sternocleidomastoid), RA (rectus abdominis), and EO (external oblique) muscle activities were measured using electromyography. RESULTS: All tested muscles showed a statistically significant increase in activity after elastic band exercise. There were significant differences in PM, SCM, RA, and EO results after chest expansion exercise using elastic band. SCM showed the largest increase in activity after use of elastic bands, at $52.37{\pm}45.88$%, followed by the RA ($50.56{\pm}79.31$), EO ($35.42{\pm}35.45$), and PM ($31.72{\pm}25.64$). The increase in the SCM was greatest, followed by increases in the RA, EO, and PM CONCLUSION: These finding suggest that activity of accessory respiratory muscles increases with use of elastic bands during chest expansion exercise in cerebral palsy.

To examine the prevalence and type of lesions in urinary bladder of Korean cattle, a random sampling survey was performed at a Jeonju abattoir in September 2000 and January 2001. Collected urinary bladder were examined grossly and histopathologically and the patterns of disease were investigated with season and sex. Of 735 cattle(99 bulls and 246 cows in September and 141 bulls, 3 steers, and 246 cows in January) surveyed, $26.3\%$ cattle with evident lesions were found. The most common gross finding was urolithiasis of urinary bladder($23.8\%$). Other lesions included hemorrhage($5.9\%$), congestion($4.1\%$), hematuria($2.7\%$), pyuria($0.7\%$), hyperplasia($0.5\%$). Urinary calculi collected in this study contained 80 to $90\%$ of calcium oxalate and 10 to $20\%$ of struvite, with or without $20\%$ of cystine and $10\%$ of uric acid. This study on urolithiasis and pathology of urinary bladder of slaughtered Korean cattle revealed subclinical aspects and management problem in Korean beef product.

CJ-10882, (E)-[(3-Cyclopentyloxy-4-methoxyphenyl)methylene]hydrazine-carboxamide, is a newly developed type IV phosphodiesterase isozyme (PDE IV) inhibitor. To investigate the subacute toxic effects of CJ-10882, it was administered to both male and female dogs at 0, 25, 50, 100 or 200 mg/kg/day orally for up to 2 weeks. During the test period, clinical signs, mortality, body weight, food consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, gross finding, organ weight, and histopathology were evacuated. Several clinical signs were observed in treated dogs at above 25 mg/kg, including salivation and vomiting. A reduction in the body weight was observed in both sexes at above 50 mg/kg. There were no treatment-related effects on mortality, ophthalmoscopy, urinalysis, hematology, sect biochemistry, necropsy findings, and histopathology in any treatment group. The results of this study demonstrate that CJ-10882, a selective Inhibitor of the type IV class of PDE, may cause effects on gastrointestinal tract and salivary glands. Therefore, these organs should be closely examined in studies with other PDE IV inhibitors.

After the first-ever international espresso coffee shop Starbucks Korea opened its first branch near Ewha University in Korea, positioning of divers foreign cultures among us and changes of life style due to the gross income growth have leaded to the growth of the number of needs for espresso coffee shops and, therefore, international espresso shops have been launching their shops in Korea. While the foreign shops have been holding most of the domestic market share, domestic espresso coffee shops like Hollys and Angel-In-Us have been penetrating the market with differentiated marketing strategies that a espresso coffee shop is no longer considered as just a shop, but a cultural product to Korean. Along with the recent changes, customers have started to laying emphasis on interior and each of the domestic coffee shops has been changing its interior designs by establishing own brand identification. Base on the Starbucks' success case, the domestic coffee shops have been adopting emotional marketing which would stimulate and arouse customers' emotions. The purpose of this study is to present systematic data which would be applied in an espresso coffee shop planning by researching applied emotional design elements of the domestic coffee shops interior designs in depth and finding their characteristics.

We report a case of 54 years old male with malignant meningioma originating in the posterior fossa with multiple recurrences, intracranial and extracranial metastases. In spite of gross total removal of tumor and conventional external radiation therapy(CERT), 2 more recurrences, 5 more intracranial metastases and 1 extracranial metastasis to the rib were developed. We tried fractionated stereotactic radiation therapy(FSRT) and CERT to the intracranial metastasis with satisfactory result. Extracranial metastasis to the rib was resected and histological finding was similar to that of original tumor.

This study was conducted to examine how Korean women mange energy metabolism during lactation. Eighteen women recruited were healthy, had normal pregnancies and were required to breast-feed their babies exclusively for at least 12wks. During the study period, all subjects were visited and interviewed five times : 3d, 9d, 4wk, 8wk, and 12wk lactation. Body composition variables were analyzed by a bioelectrical impedance method, energy intakes were assessed by using the inventory-weighing method, energy expenditure were determined by recording daily activities, and milk energy output was investigated from the amount of milk production and the gross energy content of milk. The subjects consumed less energy than current recommended allowance all over the study period, but compatible with fairly adequate lactational performance. They responded the additional energy stress of lactation by enhancing metabolic efficiency, increasing energy intakes, reduction physical activities and mobilizing body reserves. Another finding in this study was that the reduction in body fat-free mass may be the one way that women meet the energy demands of lactation like the reduction in body fat mass. The results from this study suggest that current recommended additional energy need during lactation, 2.09MJ/d(500kcal/d), is too high for healthy Korean women. Our data also indicate that the changes of body composition and energy balance at earlier postpartum are extremely different from those at later periods.

The present study was conducted to investigate the potential subacute toxicity of CJ-10882 by a 4-week repeated oral dose in dogs. The test article was administered once dally by gavage to dogs at dose levels of 0, 2, 10, and 50 mg/kg/day for 4 weeks. During the test period, clinical signs, mortality, body weights, food consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, gross finding, organ weight, and histopathology were evaluated. Several clinical sign were observed in treated dogs at 50 mg/kg, including salivation and vomiting. Increase in the serum level of ALT and albumin observed in the female 50 mg/kg group was considered as a toxic effect related to the test article since the histopathological change in Liver was accompanied. There were no treatment-related effects on mortality, food and water consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, necropsy findings and organ weights in any treatment group. Based on these results, target organ was not observed and the no-observed-adverse-effect level (NOAEL) was 10 mg/kg/day and the absolute toxic dose was 50 mg/kg for both male and female dogs.
