    Notes: Abstract Background. Metachronous solitary metastasis of renal cell carcinoma (RCC) to the contralateral adrenal gland is very rare. We assessed the clinocopathological findings of such patients who received adrenalectomy. Methods. We retrospectively reviewed the records of all 495 patients who underwent nephrectomy for RCC; excluding those in stage IV, between 1980 and 1993. Of these patients, 5 who showed metachronous solitary metastasis to the contralateral adrenal gland, and also received adrenalectomy were the subjects of this study. Results. The adrenal metastasis was found between 14 and 132 months (median, 81 months) after nephrectomy. After the solitary adrenalectomy, patient survival ranged from 450 to 2160 days (median, 660 days); 2 patients were alive with no evidence of disease at 660 and 1830 days, respectively, and 3 patients died of this disease, at 450, 480, and 2160 days, respectively, after adrenalectomy. The overall survival rate was 100% at 5 years, 80% at 6 years, 60% at 7 years, and 40% thereafter. The 2 patients with no evidence of disease did not receive steroid supplementation, because they had not received ipsilateral adrenalectomy. No significant difference was observed between survivors and non-survivors in terms of clinicopathological factors such as affected side, location of the tumor, tumor size of primary/metastatic lesion, and stage or grade of primary/metastatic lesion. From the viewpoint of outcome, patients with early recurrence tended to show an unfavorable prognosis compared with prognosis in those with late recurrence. Conclusion. The prediction of outcome in patients with RCC who undergo, adrenalectomy for metachronous solitary metastasis to the contralateral adrenal gland is difficult. Although the factors that affect prognosis are uncertain, long-term observation for unusual metachronous metastasis to the contralateral adrenal gland is mandatory in patients with RCC.

    The effects of S1319, a novel marine sponge-derived β2-adrenoceptor agonist, on IgE-mediated activation of human cultured mast cells (2000)

    Notes: Abstract. Objective: This study aimed to evaluate the abil-ity of S1319 (4-hydroxy-7-[1-(1-hydroxy-2-methylamino) ethyl]-1,3-benzothiazol-2(3H)-one acetate), a novel β 2-adrenoceptor selective agonist derived from marine sponge, to inhibit IgE-mediated activation of human cultured mast cells (HCMC) in vitro.¶Materials and Methods: We examined the effect of S1319 (racemate) on tryptase release and tumor necrosis factor- α (TNF-α) production in HCMC generated from human cord blood cells, after cross-linking of high affinity immunoglobulin E receptors (FcεRI), compared with those of the non-selective β-adrenoceptor agonist, isoproterenol (R-isomer), the selective β 2-adrenoceptor agonist, salbutamol (racemate), and the selective and long-acting β 2-adrenoceptor agonist, formoterol (racemate). We also evaluated the effect of S1319 on the intracellular cAMP level, inositol phosphate production and protein tyrosine phosphorylation in HCMC.¶Results: S1319 and β-adrenoceptor agonists inhibited the IgE-mediated release of tryptase. Approximate IC50 values of S1319, formoterol, isoproterenol and albuterol for the inhibition of tryptase release were 0.51 ± 0.12, 0.15 ± 0.1, 0.80 ± 0.09, and 28 ± 32.4 nM, respectively. S1319 and β-adrenoceptor agonists also inhibited TNF-α production by HCMC in a concentration-dependent manner. Approximate IC50 values of S1319, formoterol and isoproterenol for the inhibition of TNF-α production were 0.19 ± 0.03, 0.28 ± 0.02 and 0.32 ± 0.03 nM, respectively. S1319 caused a concentration-dependent increase in total cell cyclic AMP levels in HCMC. On the other hand, S1319 inhibited the accumulation of inositol 1,4,5-triphosphate and IgE-mediated protein tyrosine phosphorylation of 42-kDa protein, p42 mitogen activated protein (MAP) kinase (ERK-2).¶Conclusion: These results indicate that S1319 and β-adrenoceptor agonists are potent inhibitors of the IgE-mediated release of mediators from HCMC.

    Notes: Abstract We found that a short synthetic peptide corresponding to the “antisense homology box” of Fas ligand induced apoptotic cell death of Fas-expressing human ovarian cancer cell lines. The peptide was deduced from residues 256–265 of human Fas ligand, based on the hypothesis that it should contain a specific binding site to the corresponding Fas. Interestingly, the ovarian cancer cell line NOS4, which was sensitive to anti-Fas antibody induced apoptosis, was not affected by the peptide, whereas another cell line, SKOV-3, which was insensitive to anti-Fas antibody, was killed by the peptide. Thus, this short peptide was shown to have a unique activity to induce apoptosis in human ovarian cancer cells in a manner different from anti-Fas antibody.
