RESUMO

Background: In this study, postoperative cardiac functions were observed in patients undergoing coronary artery bypass grafting (CABG) surgery following preoperative administration of the anti-ischemic drug trimetazidine. Materials and Methods: The study included a total of 50 CABG patients; 25 were administered with trimetazidine preoperatively and 25 did not receive trimetazidine. A retrospective evaluation was made of the parameters of age, gender, preoperative echocardiography (ECHO) results, cross-clamping durations, postoperative inotropic requirements, and postoperative 4th-h troponin-I levels and the groups were compared. Results: There was no statistically significant difference determined between the 2 groups in respect of the data of age, gender, comorbidity, preoperative ECHO signs [(ejection fraction (EF), left ventricle end systolic diameter (lvsd), left ventricle end diastolic diameter (lvdd), left atrium diameter (LA), and intraventricular septum thickness (IVS)], inotropic requirements, and postoperative troponin-I levels. In the control group, a positive correlation was determined between postoperative troponin-I levels and DM (r: 0.597, p: 0.002). There was no correlation determined in the trimetazidine group (r:-0.042, p: 0.844). Conclusion: The results of this study demonstrated a positive correlation between postoperative troponin-I levels and DM in the group not administered with trimetazidine. There was no such correlation determined in the group administered with trimetazidine. This result may suggest that DM may increase troponin-I levels in the absence of trimetazidine, and therefore that the drug may be cardioprotective in such cases. Further studies on more extensive patient populations are required to confirm these results.

RESUMO

Background: We aimed in our study to research the role of new cytokines such as IL-35, IL-22, and IL-17 that may form a target for novel treatment approaches. Methods: IL-10, IL-17, TGF-ß, IFN-γ, IL-22, and IL-35 serum levels of allergic rhinitis (AR) patients were measured using ELISA method. Allergic sensitization was demonstrated by the skin prick test. Patients only with olive tree sensitivity were evaluated for seasonal AR (SAR). Patients only with mite sensitivity were included in the study for perennial AR (PAR). AR clinic severity was demonstrated by the nasal symptom scores (NSS). Results: In total, 65 AR patients (patient group), having 31 PAR and 34 SAR patients, and 31 healthy individuals (control group) participated in the study. Cytokine levels between the patient group and the control group were compared; IL-17 (p = 0.038), IL-22 (p = 0.001), and TGF-ß (p = 0.031) were detected as high in the patient group, and IFN-γ (p < 0.001) was detected as low in the patient group. When correlation analysis was made between age, gender, prick test result, NSS, AR duration, and cytokine levels in the patient group, a negative correlation was detected only between IFN-γ (p = 0.032/r = -0.266) level and NSS. Conclusions: Accompanied by the literature information, these results made us think that T cell subgroups and cytokines have an important role in AR immunopathogenesis. It is thought that future studies to be conducted relating to this subject will form new targets in treatment.

RESUMO

OBJECTIVES: In addition to its antimicrobial effects, inhibitory effects of minocycline have been demonstrated, including against inflammation, apoptosis, proteolysis, angiogenesis, and tumor metastasis. In this study, we aimed to determine the beneficial effects of minocycline on lung histology and its antioxidant activity in a murine model of pulmonary fibrosis. MATERIALS AND METHODS: Twenty-eight Swiss albino mice were randomly allocated into four groups of seven animals per group. Group I (control group) received intraperitoneal injection of saline. Group II (methotrexate group) received methotrexate orally 3 mg/kg for 28 days. Group III (minocycline group) received methotrexate orally 3 mg/kg and 15 mg/kg of intraperitoneally injected minocycline for 28 days. Group IV (minocycline group) received 15 mg/kg of intraperitoneally injected minocycline for 28 days. Twenty-eight days later, the animals were euthanized. Thereafter, lung tissue samples were harvested. Histological findings of airways were evaluated by light microscopy. The levels of malondialdehyde (MDA), the product of reactive oxygen in lung tissue, and catalase, an antioxidant enzyme, were also determined. RESULTS: In the light microscopic examination, the lung tissues of the control group showed normal histological features. In the methotrexate group, the degree of lung damage (grade 3 fibrosis) was higher than the control and other groups (p: 0.001). In the minocycline-treated group, improvement in lung tissue was noted (median fibrosis score: 3 (MTX group) vs 1 (MTX plus minocycline group); p: 0.001). Only the minocycline group showed normal histological features. Although minocycline reduced the MDA levels in lung tissue, an increase in catalase activity was detected (p: 0.018 and p: 0.014, respectively). CONCLUSIONS: The administration of minocycline may be effective in MTX-induced lung fibrosis in mice. However, further studies with high-dose and long-term treatments are needed.

RESUMO

AIM: The study is aimed to determine the beneficial effects of methyl palmitate (MP) which has antioxidant and anti-inflammatory effects demonstrated on murine model of acute lung injury induced by lipopolysaccharide (LPS). MATERIALS AND METHODS: Forty male BALB/C mice were randomly allocated into four groups (n=10, each): control group, methyl palmitate group (300 mg/kg), LPS group, and methyl palmitate -treated groups. Methyl palmitate or vehicle was given with an intraperitoneal administration 1 h before an intratracheal instillation of LPS (5 mg/kg). The severity of pulmonary injury was evaluated 6 h after LPS challenge. All experimental procedures complied with the requirements of the Animal Care and Ethics Committee of the Adnan Menderes University. RESULTS: Methyl palmitate pretreatment significantly attenuated LPS-induced pulmonary histopathologic changes, alveolar hemorrhage, and neutrophil infiltration. Methyl palmitate pretreatment also reduced the concentrations of malondialdehyde in lung tissues. CONCLUSIONS: This study indicates that methyl palmitate may have a protective effect against LPS-induced acute lung injury, and the potential mechanism of this action may involve the inhibition of NF-κB. activation.

RESUMO

BACKGROUND: Changes in glomerular filtration rate (GFR) provide a valuable indicator of the progression of diabetic nephropathy (DN). This study was designed to demonstrate the clinical values of serum cystatin C (Cys C) and beta2-microglobulin in the assessment of renal function in type 2 diabetics by comparing them with the GFR, estimated from the uptake phase of 99 m technetium dimetiltriamino pentaacetic acid renogram (GFR-DTPA) and creatinine clearances. MATERIALS AND METHODS: 68 type 2 diabetic patients with (urinary albumin excretions (UAE) 30 - 300 mg/24 h) (n = 39) and without (UAE < 30 mg/24 h) (n = 29) microalbuminuria and 32 controls were enrolled in the study. Serum Cys C, beta2-microglobulin, creatinine, urinary microalbumin levels, creatinine clearances and GFR-DTPA values were determined in all groups. Non-parametric ROC curves, using a cut-off GFR-DTPA of 60 mL/min/1.73 m (2), were obtained for these markers. RESULTS: Serum Cys C, beta2-microglobulin, glucose and HbA1c concentrations were significantly higher in the group with diabetes compared to controls. In the patients with microalbuminuria, serum Cys C and glucose concentrations increased significantly in comparison to patients with normoalbuminuria, while no differences were observed for beta2-microglobulin levels. Serum creatinine concentrations, GFR-DTPA values and creatinine clearances were not different between both diabetic groups and controls. Cys C was positively correlated with beta2-microglobulin and creatinine and negatively with GFR values; beta2-microglobulin was also positively correlated with serum creatinine in microalbuminurics. A significant inverse correlation was found between beta2-microglobulin and GFR values in both microalbuminurics and normoalbuminurics. CONCLUSIONS: Increased Cys C and beta2-microglobulin in diabetics may be early indicators of incipient DN. The diagnostic accuracies of Cys C and beta2-microglobulin are superior to that of serum creatinine in distinguishing between mild and moderately reduced GFR.
