The mechanism of development of pulmonary edema associated with -sympathomimetic agent is still not fully understood. 2-sympathomimetic drugs such as ritodrine, terbutaline, and fenoterol are widely used for the treatment of premature uterine contraction. We describe a case of pulmonary edema that occurred suddenly during Cesarean section in a previously healthy parturient, associated with ritodrine pretreatment for 5 days in an attempt to arrest preterm labor. Pulmonary edema was completely treated with mechanical ventilation and diuretic therapy.

BACKGROUNDS: Antiphospholipid antibodies which are frquently found in systemic lupus erythematosus and primary antiphospholipid syndrome are associated with recurrent abortions and thromboembolism. In this study the authors investigated whether antiphospholipid antibodies are found in Graves disease, a representative organ-specific autoimmune disease and what is the clinical implication of the antiphospholipid antibodies if they appear in Graves disease. METHODS: Anticardiolipin antibody and lupus anticoagulant activity were measured in 57 untreated hyperthyroid Graves patients. 42 euthyroid patients with thyroid nodules served as controls. RESULTS: Eight of the 57 patients with Graves disease had anticardiolipin antibody which was significantly more frequent than in control group. Six of the eight patients who had anticardiolipin antibody had IgM type antibody and two had IgG type antibody. All their antibody activity declined with several months of antithyroid drug therapy and finally disappeared when the patients became euthyroid. Presence of anticardiolipin antibody had no relationship with clinical events such as spontaneous abrtion and thromboembolism. CONCLUSION: Anticardiolipin antibody is frequently found in patients with Graves disease. They seem to appear as an epiphenomenon of autoimmunity and they seem not to have any clinical implications.

BACKGROUNDS: Polyamines are known to be essential for cell growth and differentiation. Recently, possible roles of the polyamine in signal transduction as neurotransmitter, modulator, or second messenger are suggested in many studies. Furthermore, it is widely studied that possible roles of polyamine are involved in the action of hormone. Thus, it was to investigate the effect of polyamines in the cell proliferation and secretion of GH from the GH cells. METHODS: Cells(5*10 cells/mL) were incubated for 3 days in DMEM containing test drugs and labeled with 20pCi/mL of [S]-methionine for 2 hr. Proteins secreted into the medium were separated by 13% SDS-gel electrophoresis, then autoradiography was performed to identify radiolabeled proteins. [S]-methionine labelled GH was identified by radioimmuno-precipitation. Total protein synthesis was determined from the radioactivity of the cell homogenate by liquid scintillation counter. The intracellular polyamine content was determined by HPLC. RESULTS: Externally added polyamines(putrescine, spermidine, spermine) induced cell proliferation in a dose-dependent manner at proper concentrations, specifically 50pM putrescine increased GH secretion, DFMO or MGBG, which is polyamine biosynthetic inhibitor, inhibited GH secretion in a dose-dependent fashion, In the cells treated with 20mM or 0.01mM MGBG, total protein synthesis were decreased only to 90 or 76% of the control levels and cell proliferation was also slightly inhibited. However the secretion of GH was severely blocked to 37% or 35% of the control. Hydrocortisone at 5 pM stimulated the secretion of GH to 153% of basal secretion, also doubled intracellular putrescine content. CONCLUSION: The present data show that externally added polyamines induced cell proliferation and GH secretion. Also, extemally added putrescine stimulated GH secretion significantly. GH secretion was inhibited by polyamine metabolic inhibitor in a dose-dependent manner and polyamine metabolic inhibitors, at proper concentrations, specifically blocked GH secretion without any significant influence on the total protein synthesis. The above results imply the involvement of polyamine in GH secretion.
