The purpose of this study was to investigate the possibility of distraction osteogenesis in membranous onlay bone graft on the mandible and to clarify the histology of bone repair during distraction osteogenesis in the membranous onlay bone in a dog model. Four dogs, 5 months of age at the beginning of the experiment, were used for this study. The zygomatic arch was exposed in the subperiosteal plane and the full-thickness zygomatic arch was harvested to 3 centimeters in length. The lateral surface of the mandibular body was exposed in the subperiosteal plane and the membranous onlay bone graft was performed with firm contact using screws. The osteotomy on the membranous onlay bone graft and underlying mandibular body was carried down week 1 in dog 1, week 2 in dog 2, week 3 in dog 3, and week 4 in dog 4 after membranous onlay bone graft. The external distraction device was applied to the mandibular body. Mandibular distraction was started 7 days after the operation at a rate of 1mm per day for a total of 10 mm distraction over 10 days. After completion of distraction, the distraction device was left in place for 6 weeks bony consolidation of the distracted area. Radiographs were carried out at 2 weeks, 4 weeks and 6 weeks after distraction. New bone between the native underlying mandibular segments was generated in the distracted zone in all dogs. The new bone between the native underlying mandibular segments was generated in the distracted zone in all dogs. The new bone between segments of membranous onlay bone graft was not generated in dog 1, but it was generated in dogs 2, 3 and 4. However, in dog 2 and 3, the new bone between segments of the distracted membranous onlay bone graft presented less firmness with fibrous tissue than that of the native underlying mandibular segment. Histologically, the distracted gap between segments of the membranous onlay bone graft was composed of much fibrous tissue in the central zone while activated osteoblastic cells formed new bone in the margins of the distracted gap in dogs 2 and 3. In dog 4, there were abundant osteoblastic activities in the distracted gap and the new bone appeared as nearly-normal cortical bone. In conclusion, these findings suggested that membranous onlay bone graft had an osteogenic capacity and that distraction osteogenesis was possible in membranous onlay bone graft.

The immunocompetence is important not only to kill the neoplastic cells but also to keep the neoplastic cells from growing further. T lymphocyte is plays the most important role in maintaining the tumor immunity efficiently. T lymphocyte has its specific functions depending in the subset of T lymphocytes. The author analyzed the T lymphocyte subsets in 31 brain tumor patients using anti-CD3, anti-CD4, anti-CD8 monoclonal antibodies and flow cytometry to determine the immunological status of brain tumor patients. All CD3, CD4 and CD8 subsets were reduced in both benign and malignant brain tumor patients but more signigicantly reduced in malignant tumor group. But in benign tumor group, the subtypes of T lymphocytes were not so different from those of normal healthy controls except the pituitary tumor patients, who showed the significant decrease in all the subtypes. In malignant tumor group, each subtype was signigicantly reduced and CD8 subtypes was markedly reduced in metastatic tumor patients, These analyses were considered to have the possibility to be contributable to planning the further immunotherapy and also the possibility to moniter the brain tumor patients clinically.

Speckled lentiginous nevus is a clinical variant of nevus-cell nevus first described by Stewart et al. in 1978. It is characterized by small, dark hyperpigmentated speckles superimposed on a tannish-brown background. The speckled areas show varying histologic patterns ranging from nevus incipiens to junctional or compound nevus. The back ground shows histologic features of Ientigo simplex. Recently, we observed clinical and histological features of 5 cases of speckled lentiginous nevi. The age of onset ranges from birth to infancy, The locations are face, thigh, back and scapula. One has zosteriform distribution in upper extrernity, chest and back. Histologic features of speckles are junctional or compound nevus. We suggest that the origin of dark speckles may be from the tannish-brown background, lentigo simplex.

This study was undertaken to investigate the effects of halothane anesthesia alone on blood glucose metabolism in ten surgical patients by determining plasma growth hormone ,(HGH), insulin and glucose, and to compare these with the effects of halothane anesthesia plus surgery. Each patient was premedicated with diazepam, 5 mg and atropine sulfate, 0. 5mg intramuscu Jarly one hour before the induction of halothane anesthesia. After endotracheal intubatien had been carried out following SCC 30-40mg, anesthesia was mairrtained with halothane and oxygen. The muscle relaxant (gallamine) in divided doses was injected during surgery when needed and ventilation was controlled or assisted intermittently throughout the procedure. A moderate depth of anesthesia was maintained according to clinical judgement, based on signs including blood pressure, pulse rate and somatie reflex responses to the surgical xtimulation. Eight blood samples were obtained from each patient:( I ) at 09.00 a.m. immediately before :induction of anesthesia (this sample served as acoatrol value) (2) the next three were after 15. 30 and 45 minutes of halothane anesthesia but before the start of the operation; (3) further three, 15,30 and 45 minutes, after the start of the operation;(4) in the recovery room after fully awaking. HGH RIAKIT was utilized as a kit for determination of human growth hormoae by radioimmunoassay and also lNSULIN-RIAKlT for insulin levels in the blood, For the determination of blood glucose level, OTB method was utilized. The ratio between male and female pgtients was 5:5, mean age 39. 2+/-12. 1 and average body weights 55. 5+/-8 .5 kg. The mean control plasma growth hormone level(HGH) in 10 surgical patients after premedication, and immediately before induction of anesthesia was 2. 03+/-0. 28ng/ml. The mean yre-surgical concentration of HGH in plasma after 15, 30 and 45 minutes of halothane anesthesia rose to 2.63+/-0.41 ng/ml, 2.76+/-0.35 ng/ml, and 2.95+/-0.42 ng/ml, respectively but these values were not significantly elevated above the control value. The plasma levols significantly increased to 3. 42+/-0. 5 mg/ml (P <0. 05), 6. 64+/-0. 6 mg/ml (p <0.001) and 7.83+/-0,75 ng/ml. (p<0.001) 15 minutes, 30 minutes and 45 minutes respectively after the start of the operation. It decreased to 3. 58+/-0. 68 ng/ml. (p<0. 05) in the recovery room when the patient awoke fully. The mean pre-anesthetic control insulin level in plasma. in 10 surgical patients was 12. 6+/-2. 0 ng/ml which was within the normal range. This level. did not vary appreciably during halothane anesthesia alone, during operation or in the post-operative period. The mean control pre-anesthetic blood glucose level was 78. .7+/-3.9 mg/100ml. It rose to 80. 6+/-2. 9 mg/100ml. 83. 2+/-3. 6mg/100 ml 30minutes, 45minutes and of halothane anesthesia alone and 15 minutes of the start of the operation but these changes were not significant. It increased significanty to 98. 2+/-4. 4 mg/100ml(p<0. 05) and 103. 9+/-4. 0 mg/100ml (p<0. 001) 30 minutes and 45 minutes respectively after the start of the surgery but it rose to 95.7+/-3.1mg/ 100ml (p <0. 01) in the post-operative period. Consequently the plasma HGH level during halothane anesthesia alone for 45 minutes was slightly, increased and rose significantly during operation and in the post-operative period. The peak level was achieved 45 minutes after the start of surgery. Plasma insulin levels did not change appreciably during anesthesia alone or during surgery. Blood glucose levels increased slightly during anesthesia alone but rose significantly during operation and in the post-operative period.

The face and notably the lips are important structures not only of aestheticvalue but also for expression, vibrancy and vitality. Sometimes we are encountered with the functional and aesthtetic lip problems especially in the patients with mandibular prognathism, such as excessive vermilion exposure, lip incompetence and hyperactivity of mentalis muscle. The etiologic factors are usually related to excessive anterior facial height, secondary to the abnormal development of perioral muscle, salivary gland and the swelling of lymphatic gland. Sometimes orthognathic surgery (mandibular setback osteotomy) alone is not accepted regarding to aesthetic value, there is likely to be a corresponding interest in adjunctive procedures such as genioplasty and soft tissue procedures. This article urges the incorporation of reduction cheiloplasty. It is a relatively minor procedure that can be easily reproducible and yields excellent, predictatable results with few complications. We treated two patients who have excessive vermilion exposure and marked abnormal lip eversion using reduction cheiloplasty combined with mandibular setback osteotomy, followed by improved facial harmony and patients were pleased.

Accurate analysis of urinary calculi is fundamental for study of the etiology of stone formation and essential for treatment of urinary stone and its prevention. A total of 600 patients underwent treatments with ESWL for urinary tract calculi between May, 1987 and June, 1989. The stone fragments that were passed with 99 patient's urine and 21 stone calculi required surgical removal, were analyzed by infrared spectrometer. The following results were obtained : 1. Mixed calculus (58.3%) in much more than single calculus (41.7% ), The most common type of calculi is calcium oxalate-calcium phosphate (69 cases-57.5% ). The most common type of components is calcium oxalate (105 cases-87.5%). 2. Uric acid stones are found in acid urine, and most of magnesium ammonium phosphate stones are found in alkaline urine. 3. 17 of 120 cases have bacteriuria on culture and most of them are ureasplitting organisms. 4. 21 calculi of failed ESWL were analyzed and the components were calcium oxalate-calcium phosphate in 14, calcium oxalate in 4, magnesium ammonium phosphate in 2, uric acid in 1. 5. The causes of failed ESWL were stone components in 5 cases, impacted stone in 10 cases and poor stone localization in 6 cases.

The coexistence of the variants of porokeratosis is very rare. We report a case of coexistence of linear porokeratosis with disseminated superficial actinic porokeratosis (DSAP). A 43-year-old wornan first noticed a brownish papule on the left side of groin in early infancy. She developed multiple discrete or confluent keratotic plaques in linear fashion on the left lower extrernity and trunk in childhood. These leaions became pruritic in summer. Two years ago, she developed multiple scattered small annular lesions on the face and forearms. Her family history showed no abnormalities. Biopsy specimene from the groin and trunk showed eornoid lamella.

BACKGROUND: Psoriasis is a chronic skin disease characterized histologically by prominent keratinocyte hyperplasia and an early inflammatory cell infiltrate. However, the pathogenesis is not fully understood yet. Recently, the evidence that T lymphocytes play a key role in the pathogenesis of psoriasis is compelling. OBJECTIVE: The purpose of this study is to evaluate serum soluble E-selectin, MCP-1 and RANTES as severity indices or disease marker. In this study, we investigated a possible correlation between disease activity in psoriasis and serum soluble E-selectin, MCP-1 and RANTES, respectively. METHODS: Fifteen patients with psoriasis and fifteen normal controls were included in this study. The patients were evaluated for the symptoms and signs according to PASI score. We measured soluble E-selectin, MCP-1 and RANTES levels with blood samples drawn from patients and normal controls. RESULTS: 1. Soluble E-selectin serum levels were significantly increased in psoriatic patients compared with normal controls (p<0.05). Moreover, a significant correlation was demonstrated between serum soluble E-selectin values and PASI scores (r=0.54, p<0.05). 2. Serum MCP-1 levels were significantly increased in psoriatic patients compared with normal conrols (p<0.05). However, no significant correlation was observed between MCP-1 values and PASI scores (r=-0.12). 3. Serum RANTES levels were significantly increased in psoriatic patients compared with normal controls (p<0.05). Moreover, a positive correlation was observed between serum RANTES levels and PASI scores (r=0.63, p<0.05). CONCLUSION: These results suggest that serum levels of soluble E-selectin and RANTES could be used as marker of the disease activity in psoriatic patients.
