Chronic complication of diving and working in compressed air is dysbaric osteonecrosis. Dysbaric osteonecrosis could be diagnosed by simple bone x-ray, in the case of exposure history to dysbaric atmosphere. The case is 44 years old man who worked as a shell fish diver for 20 years. He was exposed dysbaric atmosphere during diving. He had bone necrosis in both femur head, both distal femur and proximal tibia. He had multiple attacks of decompression sickness. Other causes of bone necrosis are ruled out. We conclude that diver's bone necrosis is dysbaric osteonecrosis.

The isomorphic response of Koebner is a well-known phenomenon commonly associated with psoriafsis, but it has been also descrilbed in conjunction with a host of other disordered. We described five cases of erythema multiforme showing lesions of easily recognizsble Koebnei phenomena. Traumas to the skin do not cause erythema multiforme, however when a patient is in an active stage of the disease, physieal factor such as traumas occuring in normsl daly-life may contribute to the distribution of skin lesions as have been seen in our patients ; clinicians should aware of this point for better understanding of clinical features in erythema multiforme.

Systemic lupus erythematosus is a systemic disorder which has frequent involvement of gastrointestinal tract. Non specific symptoms such as anorexia, nausea, diarrhea and abdominal pain are well known symptoms when the gastrointestinal tract is involved. The most feared gastrointestinal complication of systemic lupus erythematosus is lupus enteritis. The pathological change in lupus enteritis is usually a result of mesenteric vasculitis. Major complications such as intestinal bleeding and perforation may occur and sometimes result in sugery. Because of high mortality rate in case of major complications, early diagnosis and appropriate treatment is very important. We experienced three patients with lupus enteritis who presented with severe abdominal pain and dirrhea. They were diagnosed by characteristic radiographical findings of small bowel series and barium study. All radiographical findings has been resolved completely with the steroid therapy. Conclusively we can induce complete remission by steroid therapy alone, if we diagnose lupus enteritis in the early period of disease course.

An isolated granulocytic sarcoma (chloroma) of the left ovary occured in the absence of leukemia in a 12-year-old woman. This lesion is defined as a localized tumor mass composed of immature cells of the granulocytic series. Granulocytic sarcomas can occur at extramedullary sites including ovary but, isolated myelosarcoma in the absence of usual manifestations of AML may be rare and has some difficulties in diagnosis. Contrary to findings in other series, granulocytic sarcoma arising in this nonleukemic patient did not progress to acute leukemia during two years she has been followed.

The extensive traumatic wound has posed a serious problem to the surgeon. Various drugs and dressing methods have been used for this kind of wound but there has been no ideal method. The pigskin xenograft was used initially for the treatment of burn wound. The salutary effect of porcine xenograft are the stimulation of growth of healthy granulation tissue, as well as epithelial borders, inhibition of bacterial growth and pain relief. We have performed porcine xenograft in 20 cases having extensive traumatic wound with skin defect from January 1981 to February 1982. The results obtained are as follows: 1. Protect large open wound until autograft are available. 2. Alleviate pain in the wound. 3. Promote granulation tissue growth which is needed for early autograft. 4. Protect the exposed wound areas (bone and tendon) from infection. 5. The healing time of the wound depended upon the severity and the state of underlying tissue in the wound rather than wound size.

BACKGROUND: Phospholipase A2 (PLA2) has been known to be involved in the pathogenesis of acute lung injury (ALI) including ARDS. Since doxycycline has the property of inhibiting secretory group II PLA2, the therapeutic effect of doxycycline hyclate was investigated for gut ischemia/reperfusion (I/R)-induced ALI in Sprague-Dawley rats. METHODS: ALI was induced in Sprague-Dawley rats by clamping of the superior mesenteric artery for 60 min, followed by 120 min of reperfusion. To confirm the pathogenetic mechanisms of this ALI associated with neutrophilic oxidative stress, we measured bronchoalveolar lavage (BAL) protein content and lung MPO, and performed cyto chemical electron microscopy for detection of free radicals, assay of PLA2 activity and cytochrome-c reduction assay. RESULTS: In gut I/R-induced ALI rats, protein leakage, pulmonary neutrophil accumulation, free radical production and lung PLA2 activity were all increased. These effects were reversed by doxycycline hyclate. CONCLUSION: Doxycycline appars to be effective in ameliorating the gut I/R-induced ALI by inhibiting PLA2, thereby decreasing the production of free radicals from neutrophils.
