Microform cleft lip is a mild form of incomplete cleft lip, also known as a minimal occult, abortive, forme fruste cleft lip. However, it has no definition and few methods have been reported for its correction. A microform cleft lip is characterized as the incomplete union of the superficial portion of the orbicularis oris muscle. It is more prominent during facial expression than in a resting state. We confined microform cleft lip in our study to the absence of philtral skin change and a contracted position on the top of cupid's bow. During the past 5 years, 17 patients of microform cleft lip were operated on. We corrected the defect of the upper vermilion border and nostril sill with minimal incision, and repaired the underlying lip musculature in superficial discontinuity. Reduction of the widened alar base was performed. Deformed alar cartilage was dissected via rim incision, and suspended in a medial and upper direction with pull-out sutures. The most important thing is precise repair of the superficial portion of the separated orbicularis oris muscle via minimal incision, and it is best to operate after 1-year of age for accurate repair. The results were satisfactory and the parents were also satisfied. The advantages of this procedure are as follows: 1. Less visible, minimal scar on upper lip 2. Simultaneous correction of vermillion notching, deformed cupid's bow and nasal deformity. 3. Eversion of philtral ridge due to tenting effect of horizontal mattress suture 4. Philtral elongation effect by reduction of alar base and Z-plasty of cupid's bow.

5.Changes of the Lymphocyte Subset in Major Depressive Disorders and Schizophrenia.
Journal of Korean Neuropsychiatric Association 1997;36(3):444-456
An association between immunity and psychiatric diseases such as depression and schizophrenia has been suggested but has not been consistently demonstrated. In the present study immune status of major depressive disorder and schizophrenia has compared with normal controls by investigating the changes in lymphocyte subpopulation. The number of lymphocyte subpopulation was determined by monoclonal antibody staining in conjunction with flow cytometry, and following surface antigens were determined: CD3+(pan T), CD7+(pan B), CD4+(T helper/inducer) and CD8+(T suppressor/cytotoxic). Fifteen untreated depressive patients and schizophrenic patients were examined along with the control who consisted of sixteen healthy volunteers matched by sex and age. The result showed that in the depression patients, number and percent of CD8+ cells were reduced(p<.05) as compared to control, while in the schizophrenic patients, number of CD8+ cells were increased(p<.05) as compared to control. The result also showed variation between sex where in male depressives, the number of CD8+ cells was reduced % compared with male control, while female patients did not show such correlation. In addition, male depressives showed decrease in the number of B cell, compared with female depressives. In the patient group with positive symptoms as measured by PANSS, number and percentage of T cells decreased(p<.05 respectively) while percentage of B cells increased(p<.05) both as compared to control. Furthermore, in contrast with positive correlation found in depression between percentage of lymphocytes and age, a negative correlation was noted in schizophrenias between BPRS and the percentage of lymphocytes, number of CD8+ cell, and the total number of lymphocytes.

OBJECTIVE: This study was performed to assess the possible involvement of the dopamine D5 receptor gene(DRD5) in the etiology of schizophrenia. METHODS: We identified the distribution of the T978C varient of the dopamine D5 receptor gene in 100 schizophrenics and 100 normal controls in Korean population, and evaluated the association between two groups. RESULTS: There were no significant differences in genotype frequency of T978C variation and genotype prevalence of homozygotes between schizophrenic and control groups. There was no significant difference in T978C allele frequencies between schizophrenic and control groups. CONCLUSION: We present evidence of a lack of allelic association between the exonic common polymorphism of the dopamine D5 receptor gene and Korean schizophrenic patients. The assumption that the T978C varient of the dopamine D5 receptor gene has a genetic role in the development of schizophrenia was not examined by this case-control study. However, because it is considered that DRD5 may act as the expression factor for the symptoms of schizophrenia or affect the difference in an individual's susceptibility to the disease, future studies to investigate the influence of other variations of DRD5 are needed.

Cytokines are produced during the effector phases of natural and specific immunity and serve to mediate and regulate immune and inflammatory responses. In natural immunity,endotoxin directly stimulates mononuclear phagocytes to secrete their cytokines and cytokines which were produced by one cell type often regulate the synthesis of cytokined by other cells. To gain effects on the role of pro-inflammatoy cytokines(TNF, IL-1, IL-6) in the endotoxin induced uveitis, author investigated the cell counts of infilterating inflammatory cells, IL-6 bioassay in aqueous humor, mRNA analysis in the transgenic endotoxin induced uveitic mice(TNF-R(-), IL-1R(-), TNF-R(-)/IL-1R(-)). In this study, there was no significant difference in the number of infiltering cells in TNF-R(-) mice compared to congenic controls, but significant diffetence in the unmber of infiltering cells was found in IL-1R(-) and TNF-R(-)/IL-1R(-) mice. IL-6(-) levels in aqueous humor were reduced in IL-1R(-) and TNF-R(-)/IL-1R(-) mice. TNF-alpha, IL-1alpha, IL-6 mRNA were detected in all experimental mice after endotoxin injection. IL-1alpha and IL-1Ralpha mRNA were detected in noninjected TNR-R(-) mice. IL-1beta mRNA was not detected in all experimental mice without or with endotoxin injection. In conlclusion, IL-1 appears to have a more important role in endotoxin induced uveits than TNF. Though IL-6 is detected in endotoxin induced uveitis, it is not an indicator for the enhenceing inflammation and may not be essential for the endotoxin induced uveitis.

OBJECTIVES: The dopamine-blocking effects and the associated side effects(amenorrhea, lactation, sexual dysfunct of classical antipsychotics in schizophrenic patients have been studied for a long time. The purpose of this study to find out these effects of new antipsychotics(risperidone, olanzapine) in schizophrenic patients treated with clinical relevant doses. METHOD: Plasma levels of both prolactin and testosterone were measured in 91 schizophrenic patients(28 taking haloperidol, 4-20mg/day ; 31 taking risperidone, 2-6mg/day/ 32 taking olanzapine, 5-20mg/day). RESULTS: In male schizophrenic patients, the prolactin levels of risperidone group(76.44+/-38.85ng/ml) and haloperidol group(60.26+/-20.74ng/ml) had no significant difference, but were significantly higher than that of olanzapine(26.90+/-5.36ng/ml). In female, the prolactin level of olanzapine group(36.66+/-17.55) was significantly lower than those of risperidone(121.7+/-.33) and haloperidol group(161.66+/-37.53). And prolactin level of risperdone group was lower than that of haloperidol group. While the testosterone plasma level of risperidone, haloperidol and olanzapine in both male and female schizophrenic patients had no significant difference. CONCLUSIONS: At doses known to be effective in popular clinical setting, prolactin level in patients taking risperidone we higher than that of haloperidol, while olanzapine showed no significant difference in terms of prolactin plasma level haloperidol. New antipsychotics may not influence the testosterone plasma level.

In North East Asians, they have many anatomical characteristics different from Caucasians: thick skin, heavy subcutaneous tissue, relatively weak SMAS and platysma muscle, prominent zygoma and mandible. In addition, Caucasians have lean and narrow face, so facial flap can easily be lifted superiorly and posteriorly, but North East Asians have short and wide face, so facial flap cannot be lifted easily in a three dimensional direction especially superiorly and posteriorly. Recent facial rejuvenation has been improved to solve these problems through various combined adjuvant surgery. We performed facial rejuvenation with following surgical emphases:1. Shaving and infracture of zygomatic prominence and multistaged curved osteotomy of the prominent mandibular angle, body and symphysis 2. Earlier Skin resection before flap dissection protects the skin incision margin 3. Sufficient fat removal by facial liposuction4. Plane of dissection; suborbicularis and submalar fat pad in midface: preplatysmal layer in lower face and neck 5. Excision of lateral part of orbicularis oculi muscle for correction of crow's feet. 6. SMAS plication and platysmal sling. Based on our experiences, we offer these personal techniques for facial rejuvenation of North East Asians.

Fractures of the tibial pilon are the severe injuries to the ankle joint resulted from axial compression, shear and/or rotational forces. The mangement has been notoriously difficult due to the comminution of the distal tibia, articular incongruity and soft tissue trauma. The advocated treatment sequence of fibular reconstruction, restoration of the articular suface, bone grafting of defects and the use of an anterior or medial neutralization plate, early movement and delayed weight bearing, were performed recently and the best results have been obtained. The results of treatment of 18 cases were analysed at the Department of Orthopedic Surgery, Chonbuk National University Hospital and Chong ju Lee Rha Hospital from Mar. 1982 to Aug. 1989. The results were as follows. 1. The most frequent type of fracture was type III according to Ruedi and Allgower's classification. 2. The operative treatment was performed with plates and screws in fourteen cases. 3. The overall good and fair results were 72%.
