This study was designed to investigate the effect of substitution of strontium for calcium on mechanical activity in isolated perfused spontaneously beating rat hearts. The mechanical activity of the hearts of Langendorff's preparation in conditions of low calcium and strontium-substitution for calcium was compared. The effect of norepinephrine and verapamil were also observed in those conditions. The results were as follows: 1. In low calcium, the mechanical activity of the heart preparation was significantly reduced, but when the equimolar strontium was substituted for the reduced calcium, the activity was kept at similar level to the normal condition. 2. When equimolar strontium was substituted for the total calcium in perfusate, the heart preparation stopped its beating, and it was not restored in spite of reperfusion with normal calcium perfusate. 3. Norepinephrine-induced positive inotropic effect was inhibited in low-calcium condition especially with low concentration of norepinephrine, but not in strontium-substitution for calcium. 4. Verapamil reduced the activity of the heart both in low-calcium and strontium-substitution as well as in normal calcium conditions. From above results, it was concluded that strontium served as a substitute of calcium in maintaining mechanical activity and in responsiveness to norepinephrine, and the influx of strontium through cell membrane is inhibited by verapamil as the influx of calcium.

Nitrofurazone is a well known sensitizer and is widely used particularly in surgical department for the treatment of secondary infection, but the reports of all ergic contact dermatitis to nitrofurazone are rare in Korean literature. We experienced a case of allergic eontact dermatitis to 0.2% nitrofurazone in 31-year-old female after dressing the grafted wound on the left index finger with the gauze embedded with 0.2% nitrofurazone olintmnt. The patch test results revealed a strong positve reaction to 0.2% nitrofurazone ointment after 48 hours.

A statistical study was done on 2205 skin tumors filed at Department of Clinical Pathology, Han Kang and Kang Nam Sacred Heart Hospital during last 10 years from 1980 to 1989. The results were summarized as follows : 1. The number of skin tumor surveyed was 2205 among total 67931 biopsy specimens, 2052 benign skin tumors, 153 malignant tumors. 2. The specimens were requested from the Department of Surgery(707 cases, 32.1 %), Dermatology(618 cases, 28.0%), Plastic Surgery(354 cases, 15.79o), and Or thopedic Surgery(223 cases, 10.1% ). 3. Among 2052 benign skin tumors, the frequently observed tumors were epidermal cyst(577 cases, 28.1%), lipoma(398 cases, 19.4%), melanocytic nevus(121 cases, 5.9 %), dermatofibroma(74 cases, 3.6%), cavernous hemangioma(72 cases, 3.5%), ea.ch of pilmatricoma and neurofibroma(63 cases, 3.1% ), granuloma pyogenicum(57 cases, 2.8%), neurilemmoma(53 cases, 2.6%), seborrheic keratosis(45 cases, 2.2%), soft fibroma(45 cases, 2.2%). 4. Among 153 malignant tumors, the frequently observed tumors were squamaus cell carcinoma(50 cases, 32.7%), basal cell carcinoma(45 cases, 29.4%), malignant melanoma(8 cases, 5.2%), Bowens disease(7 cases, 4.6%), metastatic skin tumors(7 cases, 4.6%) in order. Male to female ratio of malignant tumors was 1.6:1 and the peak age incidence was in 6th decade. 5. Male to female ratio of squamous cell carcinoma was 3.2:1 and of basal cell carcinoma 1: 1.3. The peak age incidences of both squamous cell carcinoma and basal cell carcinoma were 6th decade. The predilection sites of squmous cell carcinoma were face, neck and genitalia and those of basal cell carcinoma were face, lower extremities, neck and trunk.

The treatment of intra-articular fractures of distal radius is difficult and has various problems. Maximum recovery of wrist function is dependent on accurate and stable reduction of the radial articular surface. We analysed one hundred and five cases of intra-articular fracture of distal radius followed for more than 6 months at Yonsei University from January 1980 to September 1988 and studied the result according to the type of treatment. The results of this study were as follows; 1. The incidence was high in female who aged over 6th decade, and in male who is active aged. 2. The main cause of this injury was fall down(34.3%). 3. In a group of closed reduction and cast immobilization, the functional result was satisfactory in 45.4%. 4. In a group of closed reduction and percutaneous pinning, the functional result was satisfactory in 50%. 5. In a group of open reduction and internal fixation, the functional result was satisfactory in 83. 3%. 6. In a group of external fixation, the functional result was satisfactory in 33.3%. 7. Overall result was mainly correlated with initial severity of the injury and anatomical reduction of the intra-articular surface.

A neglected Monteggia fracture can pose a significant clinical problem because of decreased range of motion of the elbow, increased cubitus valgus, progressive damage and elbow instability. Factors leading to misdiagnosis include swelling of soft tissue, overlying of bones on radiographs and lack of inclusion of the elbow on the radiograph at the ulnsr fracture. Therefore, a radiograph that includes the elbow at the ulnar fracture should be taken. A line drawn through the shaft and head of the radius into the elbow should align with the capitulum in any projection, thereby assisting in the correct diagnosis. Three cases of neglected Monteggia fracture were treated by open reduction of the radial head with repair or reconstruction of the annular ligament and osteotomy of the ulna, and satisfactory results were obtained.
