Background: Inter1eukin-6(IL-6) is known to be produced by osteoblastic cells and to have impartant role in regulation of bone remodelling, Most previous studies indicated that IL-6 bas a major role in stimulating osteoclastic resorption by increasing recruitment and proliferation of preosteoclasts. But its autocrine effect on osteoblastic cells has not been well established yet. Therefore, we studied the effects of IL-6 on messenger RNA (mRNA) expression of proteins that are characteristic of osteoblastic cells in human bone marrow stromal (osteoprogenitor) cells (hRMSC). Methods: The expression of mRNAs for alkaline phosphatase, al(1)-collagen, osteopontin and decorin were studied by northern blot analysis after 3 7 days' treatrnent with IL-6 in the concenttation range of 101,000 U/ml. Results: The mRNA levels for any of the osteoblastic proteins studied did not change significantly by IL-6 treatment up to the concentration of 1,000 U/ml. Conclusion: These results suggest that IL-6 does not have a significant role in differentiatian or activities of human bone rnarrow stromal.

The authors conducted a clinical observation of 13 cases of pulmonary aspergilloma at Yeungnam University Hospital from March 1983 to March 1992, and the following results were observed: 1) The male to female ratio was 1 : 1.2, and the age distribution was ranged 30 to 67 years old. 2) All cases were symptomatic : hemoptysis, cough, sputum and dyspnea. Especially, hemoptysis was the presenting compliant in 10 patients (77%) 3) The underlying lung disease were pulmonary tuberculosis in 9, COPD in 5 and bronchiectasis in 2. 3 cases were without underlying disease. 4) According to radiographic appearance, 8 cases had the typical crescent sign and 5 cases were seen nodular lesion. And the lesions of 11 cases were located in both upper lung. 5) 10 cases were treated with surgical resection. Among these cases, 8 cases were alieved and 2 cases, died. And other 3 cases were treated with conservative treatment. We suggest that these findings would be helpful for the diagnosis and treatment of pulmonary aspergilloma and further study might be needed to evaluate the prognosis of pulmonary aspergilloma.

Isolated angiitis of the central nervous system is characterized by necrotizing vascular inflammation confined to the brain or spinal cord. The present report described a 22 year old female patient who experienced abruptly developing headache, dysarthria, swallowing difficulty, quadriparesis, and mental changes. The laboratory test of her blood, urine, and cerebrospinal fluid are all within normal range. Bliateral multiple small areas of low density were noted in the deep brain, cerebellun, and brainstem on brain C-T scan. There is no specific abnormal finding on the cerebral angiogram. The steroid treatment, 3 days of the 'pulse theraphy' followed by oral administration of prednisolone, dramatically ameliorated almost all symptoms and signs at first, but her symptoms were relapsed during tapering of oral prednisolone soon after. The second trial of the steroid treatment was not effective but there was a good response to the combined treatment of cyclophosphamide (Cytoxan) and prednisolone. The repeated brainstem auditary evoked potentials (BAEP) and somatosensory evoked potentials (SSEP) were helpful to determine the clinical course, as well as fluctuating abnormalities on brain CT scans.

Malignant hyperthermia is a genetically transmitted, catastrophic, hypermetabolic syndrome that is induced by potent volatile anesthetics and/or depolarizing muscle relaxants. It is now well established that the pathophysiology is related to a malfunction of the intracellular calcium homeostasis in skeletal muscle. Morbidity has been correlated to the duration of symptoms. Dantrolene decreased release of calcium from the sarcoplasmic reticulum. We recently encountered a fulminant case during halothane anesthesia. Anesthesia was induced with thiopental and succinylcholine without jaw tightness or stiffness. After induction, tachycardia, arrhythmias, increased end-tidal CO2, and high body temperature were noted. Arterial blood gas analysis showed a severe, mixed acidosis. Intensive treatment with body cooling was immediately initiated. But dantolene could not be available. The patient died of renal failure and disseminated intravascular coagulation 41 hours after induction of anesthesia.

An outbreak of dermatosis occurred in a livestock fodder factory at Kyongju in May 1994. Authors conducted a questionnaire survey on 60 workers in the factory and a dermatologist examined their skin lesion. Authors also collected mites and identified them. The obtained results were summarized as follows; 1. Twentyeight cases of dermatosis were identified with attack rate of 46.7%. Attack rate was not different by department, age, sex, educational level and employment duration. Attack rate was 67.5% in productive worker and 5.0% in clerical workers (p<0.01) but was not significantly different between departments among productive workers (p>0.05). 2. Three cases among 28 dermatosis cases and one subject among 32 non-cases had a history of same dermatosis last year. Only one of dermatosis cases had a history of dermatosis among family members. History of other skin lesion and allergy was very rare in both cases and non-cases. 3. Skin lesions of the cases were rice-sized erythematous papules or vesicles with a central biting point. Onset date of dermatosis was between May 1 and June 10. Duration was from one day to more than 30 days. Skin lesion was most frequent at the back(75.0%). and also observed at the arms(64.3%). abdomen(60.7%), legs(57.1%), chest(32.1%) and neck (25.0%). Skin lesion was aggravated while workers are sweeping the floor(35.7%), working at the workplace(21.4%) and in bed at night(28. 6%). 4. Total l,637 mites were collected and identified into 3 suborder, 7 families and 17 species. Dermafophagoides farinae was most frequent Nnd most of the species identified were blood sucking mites. Authors concluded that the outbreak of dermatosis was brought about by mite-bites and grain beetle parasitizing Acarophenax tribolii was the most suspected species. Further studies to identify the specific species causing dermatosis and route of import are needed.

Scoliosis has been reported in 40 to 60 percent of patients with Marfsn's syndrome. The tensile strength of tissues in which the collagen is a major component has been to be reduced in this disease. An abnormality of cross-linking in the α2(I) peptide chain of collagen is the simplest explanation for this observation. We experienced a case of scolisis with Marfan's syndrome in whom Cotrel-Dubousset instrumentation was csrried out successfully and bilateral pneumothorax was observed in 10 days postoperatively. The occurrence of this complication, which has not been previously reported in the literature, suggests that excessive distractional and rotational force during procedure may be harzsrdous in the patient with intrinsic collagen weakness.

The ovarian hyperstimulation syndrome is a rare but serious complication of ovulation induction therapy with gonadotropin. The clinical manifestations are generalized edema, ascites with pleural effusion and may become life-threatening in severe cases. The pathophysiology is still unknown therefore, the treatment should be symptomatic and conservative. We report a case of severe OHSS with massive right pleural effusion in excess of ten liters after human menopausal gonadotropin therapy because of secondary infertility. Fluid and electrolyte imbalances were corrected and albumin was administered. A right chest tube was placed for a total of sixteen days, draining eleven liters of pleural effusion totally, resulting a dramatic decrease of pleural effusion and improvement of symptoms.

Infective endocarditis is a disease that is characterized by the vegetations. Although cardiac complications remain the leading cause of death, endocarditis is complex, systemic illness with involvement of virtually all the organs. The spectrum and incidence of cardiovasular, neurologic, renal complications also are presented by direct embolism and immune- mediated phenomena. Systemic embolism is the common and serious complications associated with infective endocarditis. Mycotic aneurysm by septic embolization is known complication of bacterial endocarditis, but mycotic aneurysm of superior mesenteric artery is very rare complication and approximately 10 cases has been reported in the literature. Acute hemorrhagic pericarditis is unusual clinical manifestation of bacterial endocarditis and subject to catastrophic hemodynamic compromise secondary to cardiac tamponade. We report a case of bacterial endocarditis in 23 years old male who developed acute hemorrhagic pericarditis and hemoperitoneum due to rupture of mycotic aneurysm in superior mesenteric artery with brief review of lieratures.
