Background: Univent(R) tube was designed to overcome the disadvantages of double lumen endotracheal tube for one lung anesthesia. But overinflation of the blocker cuff of an endobronchial tube can cause pressure damage to the bronchus. The purpose of this study was to evaluate whether the blocker cuff pressure and the duration of ballooning using the Univent(R) tube is correlated with the degree of bronchial mucosal damage (BMD). Methods: A total of 13 men and 7 women intubated with the Univent(R) tube were enrolled for the study. The BMD were evaluated by direct visualization using fiberoptic bronchoscopy prior to intubation and following extubation and the degree of the BMD were scored from 0 to 4 as follows; 0: normal, 1: erythema, 2: swelling, 3: hemorrhage, 4: mucosal wall tearing. Results: No change in bronchial mucosa (score 0) were observed in 11 patients (55%), erythema (score 1) in 5 patients (25%), swelling (score 2) in 3 patients (15%), hemorrhage (score 3) in 1 patient (5%) and mucosal wall tearing (score 4) is none in 20 patients. The bronchial blocker cuff pressure required to "just sealing" the bronchus was 178.1+/-37.4 mmHg with corresponding cuff volume of 6.7+/-1.0 cc. The duration of ballooning was 115.5+/-26.4 min. The correlation coefficient between the blocker cuff pressure and duration of ballooning to the degree of bronchial mucosal damage were 0.125 and 0.137, respectively, which was not statistically significant. Conclusions: The bronchial blocker of Univent(R) tube doesn't cause any severe BMD and the degree of BMD are correlated with neither the bronchial blocker cuff pressure nor duration of ballooning of Univent(R) tube.

Thirty nine cases (38 patient) of acetabular fracture and fracture-dislocation were treated in our hospital during the period 1973 to 1977. The short summary of the observation were as follows; 1. Among 39 cases (24 were male and 15 female), the most common cause of acetabular fracture and fracture-dislocation was traffic accident. 2. The acetabular fractures and fracture-dislocations were treated by conservative measures in 25 cases and by open reduction in 14 cases. The results were as follows; excellent in 12(30%), good in 19(48%), fair in 5 (15%) and poor in 3 cases (7%). 3. Among 3 cases of poor results, secondary traumatic arthritis and limitation of motion were observed in two cases and aseptic necrosis of the femoral head, in one case. 4. The result of conservative treatment was satisfactory if the stability of the hip joint and the congruity of the superior weight bearing dome of the acetabulum was well preserved.

The bone formation of periarticular connective tissue after head injury and total hip arthroplasty is included in the category of heterotopic ossification. Induction of a new bone formation in the soft tissue is related to various materials such as bone morphogenic protein. The alkaline phosphatase and acid phosphatase act as important factors in the formation and absorption of the bone. The acid phospatase has the important function of acting as the control with specific activity of phosphatase in vivo. Cholecalciferol induces absorption of the calcium in the alimentary tract and bone resorption and increment of bone calcification, whereas disodium etidronate inhibits the deposition and dissolution of calcium salt and formation of heterotopic bone. This paper reports on the relationship of alkaline phosphatase and various phosphoaminoacid phosphatase which affect the cellular differentiation and remodelling in the heterotopic ossification, with the effect of cholecalciferol and disodium etidronate on the heterotopic bone induction in rats. The following results were obtained: 1. The contents of the calcium in the implanted bone matrix increased markedly from two to five weeks. There was no changes in the calcium content by cholecalciferol or in the administration of small doses of disodium etidronate (5mg/kg). However, in the administration of large dose of disodium etidronate (25mg/kg), calcium mobilization was totally suppressed for the whole period of the experiment. 2. The protein content in the implanted bone matrix did not much change for the whole period of the experiment and the administratinn of cholecalciferol or disodium etidronate also had no effect on the protein content. 3. The activities of alkaline phosphatase in the implanted bone matrix peaked at two weeks in control or cholecalciferol group, whereas disodium etidronate admninstration caused the highest activity in the third week. 4. The activity of acid phosphatase in the implanted bone matrix increased in first and third weeks by cholecalciferol treatment. Disoidum etidronate inhibited the activity of the acid phosphatase in the first, fourth & sixth weeks of implantation. 5. The activity of phosphoserine phosphatase increased due to cholecalciferol treatment, but was significantly inhibited by disodium etidronate (25mg/kg) treatment. 6. The activity of phosphothreonine phosphatase in the implanted bone matrix slightly increased due to cholecalciferol treatment, whereas the activity decreased significantly for the whole period of the experiment by disodium etidronate (25mg/kg) treatment. 7. The activity of phosphotyrosine phosphatase in the implanted bone matrix was not change much for the whole period of the experiment and the administration of cholecalciferol or disodium etidronate had no effect on the activity of phosphotyrosine phosphatase. In conclusion, the disodium etidronate (25mg/kg) almost completely inhibited the molilization of calcium and the activities of acid phosphatase, phosphoserine and phosphothreonine phosphatases. Therefore, it can be suggested that the above phosphatases are closely related to the action mechanism of disodium etidronate.

Leiomyoma is commonly found in the female genital tract, but occurrence in the urinary bladder is very rare with only 235 cases reported in the literature. These tumors have been classified as intravesical (63%), intramural (7%) and extravesical (30%) depending on the direction of the growth. We report a case of intravesical leiomyoma of the urinary bladder in a 36 year-old woman who exhibited dysuria and urinary retention. The gross and microscopical findings of leiomyoma of the bladder are similar to those of the uterus. Immunohistochemical stains for estrogen receptor (ER) and progesterone receptor (PR) revealed diffuse nuclear staining in smooth muscle cells, supporting the hypothesis of hormonal influence in tumorigenesis.

Granular cell tumor is one of the rare tumorous condition. At present there are estimated 600 reported examples of the tumor in the medical literature. Malignant granular cell tumor is a well established but extremely rare entity that is found in appr- oximately 2 % of all granular cell tumor. Diagnosis should be restricted to neoplasms that are similar in their histological appearance to benign granular cell tumors but can be seperated on the basis of cellular pleomorphism, mitotic activity, and, most importantly, their capacity to produce metastases. The authors had experienced that a 55 years old male patient had two large malignant granular cell tumors at the left thigh and left inguinal area with metastatic lesion.

We analyzed the results of the prostate biopsies of 64 patients with elevated serum PSA (>4ng/ ml) at Kangbuk Samsung Hospital from March 1993 to February 1996. Of 64 patients, 11 patients (17%) had prostate cancer and 53 patients (83%) were diagnosed as benign prostatic hyperplasia. Among the patients with prostate cancer, 1 patient had serum PSA between 4.1 to 10.0ng/ml, 2 patients between 10.1 to 20.0ng/ml and 8 patients above 20ng/ml The detection rates of prostate cancer in each serum PSA levels were 3%, 15% and 36% respectively. Two of 17 patients with both negative DRE and TRUS were diagnosed as prostate cancer Two of 21 patients with positive TRUS and negative DRE had prostate cancer but none of 8 patients with positive DRE and negative TRUS had prostate cancer. Seven of 18 patients with both positive TRUS and DRE had prostate cancer. The sensitivity, specificity, positive predictive value and overall accuracy of DRE and TRUS in patients with elevated PSA (>4ng/m1) were 64%, 64%, 27%, 64% and 82%, 43%, 23%, 50% respectively in patients with elevated serum PSA (>4ng/ml). In conclusion, these results suggest that prostate biopsy in early diagnosis of prostate cancer would be needed for the patients with elevated serum PSA (>4ng/ml) regardless of the results of DRE and TRUS.

We report a case of renal pelvic calcification and ossification simulating a renal pelvic stone. histopathological examination of resected kidney revealed submucosal calcification in the pelvic and ossified foci in the perivascular area. This is the first report in the Korean literature and have been reported 1 case in the English literature till now. This is very rare entity unrelated to amyloidosis.
