Authors review the clinical and histopathologic findings of 41 EIenoch-Schonlein purpur.a patients and attempt, to clarify the association between abnorma] urinary findings and anti-streptolysin 0(ASLO) titer and performed the direct immunofluorescence(',E)II) study on skin lesion to investigate the pathogenetic mechanim of renal involvement. The results were summarized as follows : 1. Ag(, distribution was form 3 month to 63 years and mean age was 18.9 years. male to female ratio was 1.2:1(22 males '. 19 females). 2. In he past history, there were preceding upper respora.tory infections in 25(61:o)patients and drug history in 10(24.3%)patients. 3. (linical manifestations in the order of frequency were as follows : arthralgia (60.9%), hematuria or albuminuria(43.8%), abdominal pain(21.9%), and positive occult: blood test(7.3%)in stool examination. 4. In the laboratory fiindings, leukocytosis was cleveloped in 14.6%, anemia in 2.4%, increased eryttrocyte sec1imentation zate in 12.3% increased ASLG titer in 43.9% of patients, and serum IgG was increased in 4 of 20(20.6)patierits, IgA in 4 of 21(19%)patients, IgM in 1fo 19(5.3o)patients. 5. Because correlation between increased A.LO titer ancl ahnoormal urinary findings wa.s high(x-test, p< 0.0,5), increased ASI,O titer may be inclicator of renal involvement. 6. DIF stuc].y was per formed in 34 patients. All showed positive reactiviy. IgG(17%), IgA(29.4% ), Clq(14.6%), C3(12.2% ), fibrinog.n(82.4%) were deposited around the vessel wall in a granular pattern. 7. There was statistically significant increase in mean serum IgG value in patients with abnormal urinary findings( t test, p < 0.05 ).

Surgery for a mid-esophageal lesion requires an open thoracotomy, But authors resected out a stenotic thoracic esphageal lesion with laparoscopic instrument without open thoracotomy. The patient was 50 years old woman with a long history of progressive dyaphagia. A small (3 cm in diameter) smooth ovoid submucosal mass lesion was found at 26 cm distal from incisor on both esophagoscopy and esophagogram. Two 5 mm and two 10 mm trocars were inserted into the right pleural cavity under general anesthesia with double lumen endotracheal tube, An induced pneumothorax by insuffulation of CO2 gas made lung collapse and a good exposure of esophagus. Transorally introduced esophagoscope helped to demonstrate the exact location of lesion and also to give a guide at safe excision of mass with prevention of mucosal perforation. The lesion was found to be a congromeration of an inflammed hilar lympnode and hypertorphic esophageal muscle. The entire lesion was carefully dissected from esphageal mucosa and resected out en bloc. A chest tube was introduced through a trocar site. The lung was reinflated immediately. Post-operatively patient was very comfortable. Laparoscopic surgery is very effective and safe, and it could be applied for the resection of lung bullae, benign pulmonary neoplasm and for an excision of benign esophageal tumor.

n-Hexane and benezene are organic compounds which have been widely used as industrial solvents. However, they are also increasingly recognized as important pollutants in working environment. The purpose of this study is to analyze neurotoxicity of benzene and n-Hexane. In this study, tibial nerve of Sprague-Dawley rats were observed after exposing them to two different concentrations of these compounds (6000 ppm of n-Hexane and 2000 ppm of benezene) which were known to be the levels to cause subacute toxicity for the three different periods; two weeks, four weeks, and sex weeks. The following results were obtained from the analysis of variance, Duncan's multiple comparison test, and regression analysis: 1) Myelin sheath thickness of nerve fiber for two n-Hexane exposed groups (four weeks and six weeks) were both reduced compared with the control group and the benezene exposed group. 2) There were positive relationships between nerve fiber diameter and myelin sheath thickness for both exposed and control groups. 3) There were significant difference in myelin sheath thickness from equal diameter nerve fibers between benzene exposed group and control group, but the greater number of thin myelin sheath were observed for n-Hexane exposed group compared with control group. Thus, it is concluded that n-Hexane tends to reduce the rate of growth of nerve fiber more than the benzene and control group. While these results shed light on understanding the effects of benzene and n-Hexane, the duration of exposure was not long enough to apply these results to real working environments. In addition, to further understand the mechanism of nerve degeneration caused by organic solvents, both epidemiological and biochemical studies should accompanied by this kind of study.

The bone formation of periarticular connective tissue after head injury and total hip arthroplasty is included in the category of heterotopic ossification. Induction of a new bone formation in the soft tissue is related to various materials such as bone morphogenic protein. The alkaline phosphatase and acid phosphatase act as important factors in the formation and absorption of the bone. The acid phospatase has the important function of acting as the control with specific activity of phosphatase in vivo. Cholecalciferol induces absorption of the calcium in the alimentary tract and bone resorption and increment of bone calcification, whereas disodium etidronate inhibits the deposition and dissolution of calcium salt and formation of heterotopic bone. This paper reports on the relationship of alkaline phosphatase and various phosphoaminoacid phosphatase which affect the cellular differentiation and remodelling in the heterotopic ossification, with the effect of cholecalciferol and disodium etidronate on the heterotopic bone induction in rats. The following results were obtained: 1. The contents of the calcium in the implanted bone matrix increased markedly from two to five weeks. There was no changes in the calcium content by cholecalciferol or in the administration of small doses of disodium etidronate (5mg/kg). However, in the administration of large dose of disodium etidronate (25mg/kg), calcium mobilization was totally suppressed for the whole period of the experiment. 2. The protein content in the implanted bone matrix did not much change for the whole period of the experiment and the administratinn of cholecalciferol or disodium etidronate also had no effect on the protein content. 3. The activities of alkaline phosphatase in the implanted bone matrix peaked at two weeks in control or cholecalciferol group, whereas disodium etidronate admninstration caused the highest activity in the third week. 4. The activity of acid phosphatase in the implanted bone matrix increased in first and third weeks by cholecalciferol treatment. Disoidum etidronate inhibited the activity of the acid phosphatase in the first, fourth & sixth weeks of implantation. 5. The activity of phosphoserine phosphatase increased due to cholecalciferol treatment, but was significantly inhibited by disodium etidronate (25mg/kg) treatment. 6. The activity of phosphothreonine phosphatase in the implanted bone matrix slightly increased due to cholecalciferol treatment, whereas the activity decreased significantly for the whole period of the experiment by disodium etidronate (25mg/kg) treatment. 7. The activity of phosphotyrosine phosphatase in the implanted bone matrix was not change much for the whole period of the experiment and the administration of cholecalciferol or disodium etidronate had no effect on the activity of phosphotyrosine phosphatase. In conclusion, the disodium etidronate (25mg/kg) almost completely inhibited the molilization of calcium and the activities of acid phosphatase, phosphoserine and phosphothreonine phosphatases. Therefore, it can be suggested that the above phosphatases are closely related to the action mechanism of disodium etidronate.

PURPOSE: The importance of the deformities in alar - columellar complex has been underestimated in Asian ethnic groups for the last few decades. Fortunately, with increasing familiarity of the open rhinoplasty techniques, the anatomic details of the nasal tip have been pointed up. Definitely, having an interest and demand for improving the sub-normal relationship between the alar rim and columella are indebted for such growing of knowledge about nasal tip anatomy. However, it is true that any single procedure is not settled as versatile and fully confident modality to correct the retracted notching of the alar rim. With this article, I would like to propose another useful option for treating retracted ala. METHODS: The authors have tried to correct alar rim retraction by means of: (1) Triangular onlay septal cartilage graft on the lower lateral cartilage with the medial end fixed to the anterior surface of the lateral crus(Alar extension graft), (2) Inserting lateral end of the alar extension graft to the vestibular skin pocket in the form of a finger-in-groove, (3) using the vestibular skin in the form of an advancement flap, and (4) using the soft shield graft to prevent possible visible step-off of the alar margin. RESULTS: The authors applied an alar extension graft to 16 patients in order to correct a retracted ala for the last 27 months (August 2003-October 2005). The distance from alar rim to long axis of nostril was improved to be within 2mm in all cases, and also the shape of the alar rim changed to a round form. Nostril asymmetry (6%) was observed in one case, temporary palpable step-off (18%) in three cases, temporary visible step-off (6%) in one case, and temporary paresthesia of the tip (25%) in four cases, respectively. CONCLUSION: The alar extension graft is simple and efficacious. It does not need donor sites other than the operative field, and its results are predictable. In particular, since it may give structural intensity to a weak lower lateral cartilage, it may be preferentially used for the correction of a retracted ala that arises from hypoplastic lower lateral cartilage. Moreover intensified lower lateral cartilage also improves the esthetic shape of lobule.
