This study was to investigate the various parts of the mandible related to inferior alveolar nerve conductive anesthesia in 228 dry skulls of Korean adults. Five morphological variations were observed and four measurements were undertaken. The following results were obtained. 1. The Position of coronoid notch in the anterior border of the ramus of mandible is classified into three types and percentage of each type was as follows : Type I (Coronoid notch in the middle part of the anterior border of the ramus of mandible) : 83.3% Type II (Coronoid notch in the inferior part of the anterior border of the ramus of mandible) : 12.7% Type III (No coronoid notch in the anterior border of the ramps of mandible) : 4.0% 2. The position of the lingula of mandible to the imaginary line of the molar occlusal plane is classified into three types and percentage of each type was as follows : Type I (Above the imaginary line of the mandibular molar occlusal plane) : 87.3% Type II (Coincide with the imaginary line of the mandibular molar occlusal plane) : 8.6% Type III (Below the imaginary of mandibular molar occlusal plane) : 4.3% 3. The position of the lingula of the mandible in the internal oblique line-posterior border of the ramus of mandible dimension is classified into three types and percentage of each type was as follows : Type I (Anterior part in the internal oblique line-posterior border of the ramus of mandible dimension) : 82.9% Type II (Middle part in the internal oblique line-posterior border of the ramus of mandible dimension) : 11. 4% Type III (Posterior part in the internal oblique line-posterior border of the ramus of mandible dimension) : 5.7% 4. The position of the apex of the lingula of mandible to the deepest point of the coronoid notch in the anterior border of the ramus of mandible is classified into three types and percentage of each type was as follows : Type I (Coincide with the deepest point of the coronoid notch) : 82.0% Type II (Above the deepest point of the coronoid notch) : 13.2% Type III (Below the deepest point of the coronoid notch) : 4.8% 5. The position of the apex of the lingula of mandible to the imaginary line of the mandibular molar occlusal plane is classified into three types and percentage of each type was as follows : Type I (Above the 8mm) : 65.7% Type II (Above the 5mm) : 18.6% Type III (Above the 10mm) : 15.7% 6. Angle between the line connecting the apex of the lingula of mandible-1-2 premolars in the contralateral side and median line of the mandible is classified into three types and percentage of each type was as follows : Type I (50°) : 67.2% Type II (45°) 21.4% Type III (55°) : 11.4% 7. The averages of the measurement of the various bony landmarks of the mandible related to inferior alveolar nerve conductive anesthesia were as follows : ① Distance from deepest point of the coronoid notch to internal oblique line : 9.2mm ② Distance from internal oblique line to the apex of the lingula of mandible : 11.6mm ③ Distance from deepest point of the coronoid notch to apex of the lingula of mandible : 19.7mm ④ Height of the lingula of mandible : 9.8mm

From January 1971 to December 1980 the authors observed 165 cases of chronic ulcers of the extrernities in the Department of Dermatology, Chonnam University Hospital. The results obtained can be summarized as follows. 1) During this period, the mean average percent of ulcer patients seen was 0.41 of the yearly total patients. 2) The ages of onset was quite varied with the highest group in the 5th decade. The ratio of men to women was 2.93: 1. 3) The most common predilection site was right lower extremity. 4) Leprosy, especially T-type, was the most comrnon underlying disease.

There have been numerous hypotheses about the pathogenesis of idiopathic scoliosis, but it is still unclear. There are some reports that abnormalities of contractile proteins may play a role in the pathogenesis of idiopathic scoliosis. The purpose of this report is to study the quantitative abnormalities of contractile proteins in muscles and nonactivated and activated platelets, and to determine whether or not the abnormalities in contractile proteins may play a role in the pathogenesis of idiopathic scoliosis. The materials were 21 idiopathic scoliosis patients aged from 13 years to 28 years(average 19.2 years) and 20 persons aged from 17 years to 25 years(average 20.1 years) as a control group. The electrophoretic analysis(SDS-PAGE method) was done on platelets both unstimulated and stimulated with thrombin and also on proteins of paraspinal muscles and gluteus maximus of idiopathic scoliosis patient and paraspinal muscles of control group. The results are as follows. 1. The myosin/actin ratios of triton-insoluble fractions to paraspinal muscles in convex sides of main curvatures of scoliosis patients(1.69±0.81) were significantly decreased compared to those of concave sides(2.55±1.28), gluteus maximus muscles(2.56±1.70) and control group(2.61±1.01). 2. There were no significant differences between scoliosis group and control group in the actin/myosin ratios of triton-insoluble fractions of the platelets both nonactivated and activated by thrombin. In conclusion, abnormalities of contractile protein in paraspinal muscles of convex side may play a role in the pathogenesis of idiopathic scoliosis, rather than abnormalities of systemic contractile protein.

The 6 patients with neglected rupture of the Achilles tendon were treated by end to end anastomosis using the V-Y tendinous flap originated by Abraham in 1975. A tendinous flap was developed over the tendon by making an inverted V incision, which was then repaired in a Y fashion. The postoperative results were satisfactory with no functional disability of the ankle and with recovery of muscle strength for periods of 8 months to 15 months, but slight limited dorsiflexion of the ankle in two cases were noticed. The advantages of this method are: 1. Optimum functional recovery. 2. Recovery of muscle strength and tendon contour. 3. Prevention of late stretching or possible rupture of the healed tendon at the rupture site.

Nine strains (6%) were confirmed as resistant (MIC=20ug/ml) to methicillin (MT) among 150 isolates of staphylococcus aureus. These MT-resistant staphylococcus aureus (MRSA) strains were also turned out to be more less resistant to other antibiotics tested, such as penicillin, chloramphenicol, tetracycline, and gentamicin except for cephaloridine. It was noteworthy, however, that strain MRSA 5 showed a relatively susceptible attitude toward most of the antibiotics tested, while being extremely resistant to MT only. Salt (NaC1) containing (5-3%) media did not have any significant effect on the degree of MT-resistance of MRSA strains. There was, however, such a tendency as that by the addition of salt the degree of MT-resistance was lowered in the highly MT-resistant strains while enhanced in MT-susceptible ones. It was confirmed that penicillinase did not have any effect on the MT-resistance while most of the penicillin- resistant strains produced the enzyme.
