Background: To inves gate the expression of TNF-α, IL-6, IL-10 in the plasma of pa ents with lung cancer who received radia on therapy (RT), and to analyze the correla on between these cytokines and radia on pneumoni s (RP). Materials and Methods: Pa ents with lung cancer who received 3DCRT in our hospital were prospec vely evaluated. Circula ng cytokine levels were measured with ELISA before R...

BACKGROUND Elderly patients are reportedly at higher risk of postoperative cognitive dysfunction (POCD) after inhalational anesthesia with sevoflurane. We hypothesized that the incidence of POCD would be higher in elderly patients undergoing major surgery under inhalational rather than intravenous anesthesia. We also measured plasma S-100β protein concentration as a biomarker of central nervous...

Psoriasis is a T cell mediated inflammatory skin disease. Complex network of cytokine induces and maintain the psoriatic lesion. Study was performed to evaluate the correlation between the level of TNFα and IL-6, in the psoriasis patients with HLA-Cw6. Cytokine levels were assayed by sandwich ELISA and HLA-Cw6 typing was done by microcytoxicity method. Serum TNF-α and IL-6 were significantly (p...

objective(s): the objective of this study was to investigate the hepatoprotective effect of licochalcone b (lcb) in a mice model of carbon tetrachloride (ccl4)-induced liver toxicity. materials and methods: hepatotoxicity was induced in mice by a single subcutaneous injection (sc) of ccl4. the lcb was administered orally once a day for seven days (po) as pretreatment at three doses of 1, 5, and...

objective(s):acute kidney injury (aki), a syndrome characterized by decreased glomerular filtration, occurs in every 1 of 5 hospitalized patients.  renal ischemia-reperfusion, one of the main causes of aki, is of particular importance in the setting of kidney transplantation. materials and methods: sixty male rats were divided into four groups including control, nephrectomy, sham surgery and re...

To define the mechanism(s) responsible for the negative inotropic effects of tumor necrosis factor-alpha (TNF alpha) in the adult heart, we examined the functional effects of TNF alpha in the intact left ventricle and the isolated adult cardiac myocyte. Studies in both the ventricle and the isolated adult cardiac myocyte showed that TNF alpha exerted a concentration- and time-dependent negative...

In Plasmodium-infected mammals, phagocytosis and production of tumor necrosis factor (TNF) by monocytes and macrophages are prominent features. The present work aimed at clarifying the relationship between the maturation of human monocytes to macrophages and their TNF productivity and phagocytic ability in the presence of Plasmodium falciparum-infected erythrocytes. Fresh monocytes produced a s...

OBJECTIVE It has been demonstrated that tumor necrosis factor-alpha (TNF alpha) induces apoptosis in cardiac myocytes. However, its mechanism of action is still not well understood. In the present study, we hypothesized that TNF alpha induces myocardial apoptosis by induction of inducible nitric oxide synthase (iNOS). METHODS Neonatal cardiac myocytes were isolated from iNOS (-/-) mutant and ...

Many actions of the proinflammatory cytokines tumor necrosis factor (TNF) and interleukin-1 (IL-1) on gene expression are mediated by the transcription factor NF-kappaB. Activation of NF-kappaB by TNF and IL-1 is initiated by the phosphorylation of the inhibitory subunit, IkappaB, which targets IkappaB for degradation and leads to the release of active NF-kappaB. The nonsteroidal anti-inflammat...
