BACKGROUND: Acne, one af the commonest dermatological disorders, is a disease of the pilosebaceous unit, and the primarily involved site is the face, where this structure exists in maximal density. Among the many etiologieal factors of acne, changes in the kinetics of sebum secretion in acne patients have been described, but there is no report to compare follicular density and the sebum excretion rate in different facial regions between normal and acne patients. OBJECTIVES: The purpose of this study was to compare the sebum output and follicular density in different regions of the face in women with and without acne and to evaluate the differences between the two groups. METHODS: We studied 10 normal and 14 acneic women aged 19-27. Follicular density was determined by light microscopy counting pilosebaceous units on cyanoacrylate follicular biopsy specimens. The sebum excretion rate was calculated by an image analyzer with a sebum print on Sebutape. RESULTS: 1. Follicular density was not significantly different between the normal and acne group. The number of follicles decreased from the central to the lateral aspect of the face with the highest value being on the nose tip and the lowest on the lateral forehead. 2. The total sebum excretion rate and the number of actively secreting follicles showed different patterns in the two groups. There was a decreased value in the acne group in some central regions of face. In addition, central to lateral declining pattems, shown in the normd group, were not apparent in the acne group. 3. The follicular sebum excretion rate showed large variations in both groups, without apparent central to lateral declining patterns. The confluence of adjacent follicles seemed to produce falsely low or high values compared with previous studies. CONCLUSION: Sebum production is influenced both by the number of active follicles and their individual capacity to excrete sebum, and the total sebum excretion rate was lower than normal in low grade acne in this study. Obstruction of the outflow of sebum and regression of sebaceous glands due to comnlones may account for it.

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

Despite the technical improvements in Internal flxation of neck fracture were made in recent years, complications, such as non-union of the fracture and avascular necrosis of the femoral head, are not infrequent. Various operative techniques have been proposed to secure the reduced fracture fragment till union, and to restore or improve the circulation in the femoral head. One of them is muscle-pedicle bone graft to the fracture site of neck. It is very important if one can predict the vascularity of the femoral head prior to treatment and also the healing process of the neck fracture during treatment. In the past, there have been considerable investigations to achieve these goal, but no method universally has been accepted as reliable and practical. Among them, Intra-osseous venography (I.O.V.) and sclntimetry utilizing the isotope trace techniques were widely used in recent. Authors adopted a cephalic and trochanteric I.O.V. to observe the fracture healing and to predict viabillty of the femoral head, and also tried a new technique (Indirect cepallc I.O.V.) to perform both techniques of I.O.V. at the same time. With the ald of image Intensifler, a bone marrow needle Is inserted 1 inch below the greater trochanter of femur, and when the tip of the needle is reached 0.5 to 1.0 cm near to fracture line in the marrow cavity, about 25 cc of 75% Urograffin is Injected by speed of 1 cc per second with sereial X-rays taken at 1,3,5 and 15 minutes (trochanteric I.O.V.). Then already inserted puncture needle for trochanteric I.O.V. are more advanced through the fracture line of the neck into the femoral head. About 10 cc of 75% Urograffin Is Injected by speed of 1 cc per second with serial X-rays taken (Indirect cephallc I.O.V.). The merits of this indirect cophalic l.O.V. via trochanteric route is that it is also simple and Practical and there is no significant complication: such as septic arthritis of hlp & thrombophlebitis. Difficulties of inserting the needle through the trochanter and the neck into the head and occasional unwanted hip-arthrogram are listed as the main demerits of this technique. But these demerits can be minimized by the accurate image intensifier control. A positive trochanteric venography is one in which venous drainage is established across the fracture site with opaque contrast medium being spread out diffusely into the head, and eventually draining out into the surrounding soft tissue via draining velns. While positive cephalic venography via trochanteric route is one in which contrast medium is spread out diffusely in the head and trochanteric region via crossing veins. Hereby, we performed internal fixation and an autogenous muscle-bone pedicle graft composed of the quadratus femoris muscle in 4 cases of femoral neck fracture which are confirmed that there are head viability by using of the cephalic I.O.V.. Since then, we checked the both I.O.V. every 6 wks post-operatively. The results seemed to be good in regard to bony union in all 4 cases, and we have also found that cephalic and trochanteric I.O.V. are a useful diagnostic tool in hip fracture.

Subtrochanteric fracture is well known for its difficulty in management, though various devices of rigid fixation have been developed. Each internal fixation device requires a lot of surgical instruments and the surgeon must be skillful in using them. Osteo self-compression plate which was preoperatively bent to fit the contour of the lateral surface of the subtrochanteric region was proved to be technically easy to fix these fractures without causing major complication. Present authors recommend to use this prebent Osteo self-compression device to treat this fracture when the surgical instruments are not fully equipped, and suitable fixation devices are not available, and/or the surgeon has no experience in handling the newly developed surgical instruments for the subtrochanteric fracture.
