In orthopedic trauma surgery, treatment of intraarticular distal humerus fractures is a challenge. With development of implants and biomechanical studies, surgical strategies with recommendations including preoperative computed tomography images, proper approaches and open reduction and internal fixation with dual plates have emerged. In addition, as an effort to provide stable fixation to permit early elbow motion, different methods of internal fixation, particularly plate configuration, have evolved. Using dual plates, either oriented parallel to each other or orthogonal, stable fixation has been achieved and satisfactory clinical outcomes have been reported. With rationales and advantages/disadvantages of each plate configuration, both techniques are selected according to surgeons' preference, and, in specific cases, one could be preferred over another. The key to successful fixation by either technique is obtaining anatomical reduction with restoration of two stable columns of the distal humerus.

Great strides have been made not only in the research of the endogenous electrical signals,but also in the clinical application on nonunions using exogenous electrical signals. We measured human skin steady state potentials on the anteromedial surface of the twenty-eight left proximal tibiae and investigated intraosseous induced potentials created by a capacitively coupled signal applied on the proximal tibia of ten rabbits' right hind limbs. Following results were observed: 1. Human skin epiphysio-metaphyseal and epiphysio-diaphyseal potential differences in resting state were 116.1±11.7µV, and 120.5±29.4µV, respectively(P> 0.05), while those in full weight bearing were 310.3±169.4µV, and 404.2±154.1µV, respectively (P<0.05). 2. Skin steady state potentials were affected by muscle contraction and load bearing. 3. Thraugh a sequence of applied voltage of 2, 5, 10, 20, and 30 volts peak to peak, linear increase in the intraosseous induced potentials were produced. 4. Intraosseous induced potentials increased, although their increasing rates being decelerated, with increasing frequencies of 2, 20, 60, 120, and 200 KHz. 5. Higher intraosseous induced potentials were produced,as conductive jelly was applied between the capacitor plates and skin.

We report a case of para.psoriasis variegata in a 19 year-old male patient wha has brownish flat scaly papules that are confluent in a retiform pattern characterized by symmetrical distribution on trunk and upper extremities. A skin biopsy specimen showed hyperkeratosis, focaI parakeratosis, hyperpigmentation of basal cell layer, and a mild lymphocytic perivascular infiltrate. No evidence was found for a relationship to lymphoma.

BACKGROUND: The growth of cells is closely related to components in a culture medium. There are many reports about cellular characteristics of melanocytes grown in a PMA-contained medium. However, only a few reports have been studied by using a physiologic mitogens-contained medium. To understand melanocyte in vivo, it is necessary to know the cellular biology of melanocytes grown in a physiologic mitogens-contained medium. OBJECTIVE: To investigate any differences between melanocytes grown in phorbol 12-myristate 13-acetate(PMA)-contained medium and in physiologic mitogens-contained medium. METHOD: We examined morphology, number and melanin contents of cultured human melanocytes grown in a PMA-contained medium and physiologic mitogens-, such as bFGF, ET-1 and a a-MSH contained medium. Result : The results are summarized as follows : 1. There were no significant morphologic differences between cells in PMA-contained medium and in physiologic mitogens-contained medium. 2. The number of melanocytes were significantly more numerous in PMA-contained medium on the 2nd day (p<0.05), but significantly less numerous in the same medium on the 6th day (p<0.05). So, the proliferation rate of melanocytes in PMA-contained medium became lower than in physiologic mitogens-contained medium as time went by. 3. Melanocytes grown in PMA-contained medium had significantly increased melanin contents regardless of the time (p<0.05). Conclusion : The proliferation of melanocytes was better in physiologic mitogens-contained medium, the melanization was higher in melanocytes of PMA-contained medium.

Basta(R) is one of the Phospho-amino acid group herbicide. It consist of glufosinate ammonium (18.5%), alkylether sulfate as surfactant (30%) and some solvents. Although it's WHO classification is Bade III, the intoxicated patient appears an serious clinical findings and have a 20% mortality rate. Nowadays, in Korea the ingestion of herbicidal agents for suicidal attempts is Sequent. The literature for intoxication of bipyridilium (Gramoxon(R)) as herbicide is varied, but the information for Basta(R) is poor even though the use of it tends to increase. Recently, We experienced six cases of Basta(R) intoxication and found that the patient expressed a gradually progressed depression of mentation, recent memory disturbances, convulsions, hypotension, or bradycardia because of CNS or cardiovascular effects of Basta(R) We report these cases with literature review.

The retinoic acid and retinoid(Ro 11-1430) were alternately applied topically on forty patients with acne vulgaris. Therapeutic effects and side reactions of this regimen were compared with our previous studies of the treatment with retinoic acid alone and with retinoid alone. Compared with the treatment with retinoic acid alone, the therapsutic effect of the alternating treatment was relatively superior as indicated by the markedly reduced severity of local side reactions.

We report a case of drug eruption and liver damage due to diaminodiphenyl suIfone(DDS) ingestion in a 17-year-old female. This patient had taken DDS for 20 days, 100mg-200mg daily to treat an unknown skin disease. Thereafter, she had generalized erythematous eruption on whole body, icteric sclera and fever. Liver function test showed abnormality (SGOT 514 unit, SGPT 710 unit, alkarine phosphotase 4. 3 B.U., total biIirubin 7. Oml/dl, direct bilirubin 4. 8mg/dl). The adverse reactiions to DDS are gastrointestinal intolerance, hemolytic, anemia, methemoglobinemia, agranulocytoais, hepatitis, neuritis, psychosis and a skin rash described as a fixed drug eruption, erythema multiforme, exfoliative dermatitis and toxic epidermal necrolysis. In Korea, DDS has been used for the treatment of skin diseases of various types for a long time without prescription, especially in rural areas. This trend is a significant sociomediical problem in Korea.
