Abstract

Lip swelling developed following the use of a cinnamic aldehyde-containing mouthwash in a woman with allergic rhinitis and asthma. Open application of the mouthwash on the antecubital fossae of the patient and control subjects produced immediate erythematous or urticarial responses in all tested individuals. Subsequent investigation established cinnamic aldehyde as the responsible ingredient. The incidence of positive reactions was shown to depend on site of application, vehicle, concentration, and time of reading. Of several related cinnamates, only cinnamic acid produced easily detectable responses at similar concentrations.

Pathophysiological aspects of cyclophosphamide and ifosfamide induced hemorrhagic cystitis; implication of reactive oxygen and nitrogen species as well as PARP activation.

Cyclophosphamide (CP) and ifosfamide (IF) are widely used antineoplastic agents, but their side-effect of hemorrhagic cystitis (HC) is still encountered as an important problem. Acrolein is the main molecule responsible of this side-effect and mesna (2-mercaptoethane sulfonate) is the commonly used preventive agent. Mesna binds acrolein and prevent its direct contact with uroepithelium. Current knowledge provides information about the pathophysiological mechanism of HC: several transcription factors and cytokines, free radicals and non-radical reactive molecules, as well as poly(adenosine diphosphate-ribose) polymerase (PARP) activation are now known to take part in its pathogenesis. There is no doubt that HC is an inflammatory process, including when caused by CP. Thus, many cytokines such as tumor necrosis factor (TNF) and the interleukin (IL) family and transcription factors such as nuclear factor-kappaB (NF-kappaB) and activator protein-1 (AP-1) also play a role in its pathogenesis. When these molecular factors are taken into account, pathogenesis of CP-induced bladder toxicity can be summarized in three steps: (1) acrolein rapidly enters into the uroepithelial cells; (2) it then activates intracellular reactive oxygen species and nitric oxide production (directly or through NF-kappaB and AP-1) leading to peroxynitrite production; (3) finally, the increased peroxynitrite level damages lipids (lipid peroxidation), proteins (protein oxidation) and DNA (strand breaks) leading to activation of PARP, a DNA repair enzyme. DNA damage causes PARP overactivation, resulting in the depletion of oxidized nicotinamide-adenine dinucleotide and adenosine triphosphate, and consequently in necrotic cell death. For more effective prevention against HC, all pathophysiological mechanisms must be taken into consideration.

GSH-dependent regulation of Fas-mediated caspase-8 activation by acrolein.

Activation of the cysteine protease caspase-8 by the death receptor Fas (CD95/APO-1) in B lymphoblastoid SKW6.4 cells or Jurkat T cells is associated with GSH depletion. Conversely, GSH depletion by the aldehyde acrolein (3-30 microM) was associated with inhibition of Fas-induced caspase-8 activation, although GSH depletion by buthionine sulfoximine (BSO) did not affect caspase-8 activation. In contrast to BSO, acrolein caused a loss of caspase-8 cysteine content in association with direct alkylation of caspase-8. Our findings indicate that inhibition of caspase-8 by thiol-reactive agents such as acrolein is not due to GSH depletion but caused by direct protein thiol modifications.

Indoxyl sulfate-lowering capacity of oral sorbents affects the prognosis of kidney function and oxidative stress in chronic kidney disease.

OBJECTIVES: Indoxyl sulfate shows nephrotoxicity and is a stimulating factor for progression of chronic kidney disease (CKD). This study was conducted to determine (1) whether the indoxyl sulfate-lowering capacity of oral sorbents (Kremezin [AST-120], Kureha Corporation, Tokyo, Japan; Merckmezin, Merck Hoei Ltd., Osaka, Japan) affects the prognosis of kidney function in CKD, and (2) whether oral sorbents reduce the markers of oxidative stress. METHODS: Rats with CKD were produced by 4/5 nephrectomy and were randomized into 3 groups: control rats, Merckmezin-treated rats, and Kremezin-treated rats. Kremezin and Merckmezin were administered to rats at a dose of 4 g/kg with powder chow for 16 weeks, whereas powder chow alone was administered to control rats. RESULTS: Administration of Kremezin significantly decreased serum and urine levels of indoxyl sulfate and serum creatinine and significantly increased creatinine clearance as compared with control values. The change in serum indoxyl sulfate noted from the initial to the final week showed a positive correlation with the change in serum creatinine and a negative correlation with the change in creatinine clearance. Kremezin significantly reduced urine levels of acrolein, a marker of oxidative stress, as compared with control levels. CONCLUSIONS: The indoxyl sulfate-lowering capacity of oral adsorbents affects the prognosis of kidney function in CKD. The more serum indoxyl sulfate is reduced, the better kidney function is preserved. Kremezin alleviates oxidative stress in the kidneys by reducing serum levels of indoxyl sulfate.
