BACKGROUND: Arterial blood gas analysis are highly susceptible to preanalytic error due to improper method of obtaining or handling the blood sample before analysis. The error in measurement of blood gas analysis are loss of CO2 by exposure to atmospheric air, effect of anticoagulant itself, temperature difference between the experimental subject and the measuring electrode and metabolic change which occur between blood sampling and measurement. METHOD: To study the effect of the delay in estimation of blood gas and drawn blood on values of blood gas partial pressure and pH. Blood sample were divided into 2 groups according to the method of storage, group I stored at 24~25degrees C(room temperature) under anaerobic condition. ;group II stored at 0~4degrees C(refrigerator) under anaerobic condition. The samples were analyzed by time interval through 180 minutes in each group. RESULTS: The result were as follows: 1) PaO2 decreased significantly after 10 mins in group I, whereas it decreased significantly after 20 mins in group II. 2) PaO2 increased significantly after 20 mins in group I, whereas it increased significantly after 120 mins in group II. 3) pH decreased significantly after 60 mins in group I, whereas it decreased significantly after 120 mins in group II. 4) No significant changes of bicarbonate and SaO2 were noted in each group CONCLUSION: From above results, it would be advisable to analyze the sample in a short period of time or to store in a refrigerator when the measuring will be delayed. So we highly recommend that blood gas analysis should be performed as soon as possible after sampling, especially within 10 minutes.

Conservative or surgical methods have been used for the treatment of fracture of mandibular subcondyle, but consensus has not been reached in regard to the proper management of this injury. Several problems related to the surgical procedure have led many surgeons to avoid surgical management of condylar fractures in favor of closed reduction and intermaxillary fixations. However, luxation of the condyle may lead to various long-term complications such as open bite on the contralateral side, dysfunction, deviation in opening and closing movements, as well as bone apposition leading to ankylosis. As a consequence, open reduction is preferable when the condyle is displaced. Various methods-for example, direct wiring technique, simple bone plating, dynamic compression plating-have been advocated for the treatment of fracture of mandibular subcondyle. Of such methods, a functionally-stable osteosynthesis can be achieved by compression osteosynthesis methods. Lag screw osteosynthesis is essentially a form of compression osteosynthesis in which the bone fragments are bound to one another as a result of traction from the screw. An advantage of compression osteosynthesis is that the end of a fractured bone can be maintained in an opposed position under pressure, and then primary bone healing occurs by direct osteoblastic activity within the fracture. As well, it obviates or reduces the need for maxillomandibular fixation, as well as the morbidity associated with conventional treatment methods such as facial nerve injury and bone resorption due to wide dissection. We have treated 9 cases of displaced subcondylar fractures of the mandible with the lag screw fixation system which is marketed by the Martin corporation. Mobilization and guidance of the jaw was begun from 7 or 10 days postoperatively. The radiologic and clinical evaluations showed good repositioning of the fragments and good occlusion postoperatively The disadvantage is that surgical procedures are relatively compound, and an additional procedure - removal of lag screw - is necessary after complete bone union. Lag screw osteosynthesis can be added as a another valid armament for plastic surgeons in the management of mandibular subcondyle fractures.

The series comprised 424 cutaneous reactions to drugs treated at the department of Dermatology, Medical college of Korea University, during the years 1969-1975. The whole series comprised 211 male(49. 8%) and 213 female(50. 2%) patients. Exanthernatous eruptions are the most frequent of all cutaneous manifestation of drug reactions. Antipyretic analgesics, antibiotics and antibacterial drugs were the three group inducing most drug reactions in the present study, following by herb drugs. Of the antipyretic anaIgesics, acetylsalicylic acid was the ones most of the involved, and sulfonamides were the most frequent cause of skin reactions induced by antibacterial drugs and penicillin and tetracycline were the frequent cause of skin reactions induced by antibiotics.

This study was done on 171 volunteers in order to investigate the present status of cutaneous normal flora of Candida species and the distribution of Candida species on the normal human skin in dermatologic clinic of Korea University Hospital from January, ]984 to December, 1984. Among the 171 volunteers, 115 strains of Candida species were identified by culture on the Sabouraud's dextrose agar media, germ tube test, sugar assimilation test, sugar fermentaion test and culture on corn meal with Tween 80 media, The results were summarized as follows: 1. The incidence of cutaneous normal flora of Candida species was 13, 5,5 (115 species among 855 sites) 2. Candida species were distributed in oral cavity(45 species), 4th interdigital toe web(39 species), groin(12 species), axilla(11 species) and 4th interdigital finger web(8 species) in order of frequency. 3, Of ll5 species, 45 species were cultured in summer, 27 species in autumn, 18 species in winter and 14 species in spring. 4 Of 115 Candida species, C. albicans(88 species), C. parapsilosis(12 species), C, tropicalis(8 species), C. guilliermondii(3 species) and C. stellatoidea(2 species) were identified. Two species could not be identified.

The most frequently used serodiagnostic test for syphilis in Korea is VDRL test, which is one of several flocculation tests utilizing cardiolipin-lecithin as antigen. This test remains popular because it is easily performed, inexpensive, is standard for screening purposes, and is useful for following the serologic response to treatment. A common problem is weakly reactive (or 'rough' result) VDRL test or reactive VDRL in the absence of definite evidence of present or past syphilis; the diagnosis of syphilis in these cases should be confirmed by using the specific treponemal antigen tests. The Fluorescent Treponemal Antibody-Absorption (FTA-ARS) test is the result of continued attempts to improve the original FTA procedures. This test uses virulent T. pallidum (Nichols strain) as antigen and uses fluorescein-tagged antihuman globulin as reaction indicator. The FTA-ABS test is very sensitive in all stage of syphilis, especially in early syphilis. The FTA-ABS test was carried out on 448 persons with reactive and weakly reactive VDRL tests and divided the groups of routine physical check and out patients. (countinued..)

The depth of wound level is as important as the level of the tendon injury itself. And the timing of the operative procedure is an important factor. As a rule, tendons injured outside of the flexor sheath yield much better results than those injured within the sheath. The nutritional supply of the flexor tendons is not completely understood. Many elaborate studies have outilned the vascular anatomy of these tendons, and not all authors are in agreement. It is now clear that synovial fluid within the sheath supplies nutrition to the tendon much as synovial fluid in a joint supports cartilage. With this in mind, the present study was designed to determine the effect of exposing tendons for varying periods of time on the viability of the tendon and sequential morphological changes. The results are as follows: 1. Twelve hours after tendon sheath removal, collagen fibrillar dissociation and irregular surface of the tendon sheath were noted on the chicken flexor tendons by electronmicroscopy. 2. Superficial tenocyte necrosis was created after 24 hours of tendon exposure. 3. At 3 days, inflammatory cell infiltration and thickening of the outer synovial layer were noted. After 7 days, fibrosis of the degenerated tendon started from the exposed surface. 4. The fibrous connective tissue and new blood vessel infiltration into the tendon were progressed after 7 days. From these morphological results, any interference with the synovial environment leads to a regressive change of the flexor tendons immediately. It is suggested that delayed primary wound covering procedure within three days an after exposed tendon injury is ideal, and it should by done at least 7 days after tendon exposure.
