- چکیده انگلیسی: Background and Purpose: Itraconazole therapy has been reported to control asthma in severe therapy-resistant asthma with fungal sensitization. The aim of this study was to investigate the impact of anti-fungal therapy on the treatment of severe asthma, irrespective of sensitization.
Materials and Methods: This active comparator clinical trial was performed on 110 therapy-resistant asthmatic patients who were randomly assigned into two groups of case and control. The patients in the case group were administered 200 mg itraconazole twice a day and the control group received 10 mg prednisolone after breakfast for 4 months. The asthma control test (ACT) which was used as a marker for the global evaluation of treatment effectiveness (GETE) was applied as the primary endpoint parameter. Cough, dyspnea, and sleep disturbance were measured on a scale of 1-4, with 1 representing no symptom and 4 indicating severe exhausting disturbance.
Results: Based on the obtained results, 71% of the itraconazole group demonstrated a marked improvement in the GETE score after a four-month treatment. Itraconazole was able to suppress clinical symptoms, including cough, dyspnea, and night symptoms, and their physical exam was indicative of normalization in 60% of the patients. On the other hand, the patients in the parallel group "prednisolone" were only able to control dyspnea. The ACT score represented a notable improvement with itraconazole (mean: 14 before the trial and >20 after the trial) and spirometry parameters underwent a considerable change from obstructive pattern to normal. Furthermore, adverse effects were only detected in 6% of itraconazole users.
Conclusion: The results of this clinical trial indicted the effectiveness of antifungal therapy for the control of the clinical condition of a subgroup of patients with severe steroid-refractory asthma.- انتشار مقاله: 31-01-1398

- چکیده انگلیسی: Objective: The aims of this study was to determine the effect of Propolis (resinous mixture that honey bees produce by mixing saliva and beeswax) on clinical and physiological findings of moderate persistent asthma.
Materials and Methods: Fifty-two subjects aged 44.6±18.5 years old with moderate asthma and Forced expiratory volume in 1 second (FEV1) 60-79% of predicted, were enrolled in this clinical trial. We randomly allocated subjects to receive either propolis (75 mg three times a day) or a matched placebo for one month. Primary outcome was Asthma control test (ACT) score and secondary outcomes included dyspnea, spirometry, fractional exhaled nitric oxide (FENO) and sputum cytology including inflammatory cell. Sputum induction was done by hypertonic saline and cytology slides were stained by Papanicolaou stain.
Results: Clinical findings significantly improved after the treatment. ACT scores significantly increased by using propolis (12.8±5.5 before and 18.1±4.99 after the trial), which was significantly higher than the placebo group (14.4±6.6 after the trial). The most significant physiological improvements were significant increases in FEV1, FV1/Forced vital capacity and expiratory flows. FENO showed significant decreases in the propolis group but increases in the placebo group. Cytological examination of sputum showed that the pattern of inflammation was eosinophilic in 44% subjects with an average eosinophil of 7.2±1.01%. Eosinophilia significantly decreased (p <0.05) by using propolis (7.2±1.01 and 4.3±3.1%, before and after treatment, respectively), but it significantly increased (p <0.04) in the placebo group (5.5±2.8, and 11.1±6.6%, before and after treatment, respectively).
Conclusion: Propolis improved the clinical and physiological findings of moderate persistent asthma, and it was able to suppress eosinophilic inflammation.- انتشار مقاله: 02-02-1398

- چکیده:
- چکیده انگلیسی: Background: Colorectal cancer (CRC) is widespread across the world. While conventional anticancer treatments
can help the affected patients, cells of vital organs such as the kidney, lungs, bladder and nervous system may
suffer from side effects of chemotherapeutic drugs, so that it is necessary to search for alternatives. From ancient
times, attention has focused on medicinal plants and natural products. In the current work, Camellia sinensis, whose
leaves are used to produce green tea was evaluated for anticancer effects in cell culture. Materials and Methods:
A hydroalcoholic extract of Camellia sinensis young leaves was prepared by percolation and compared with Cisplatin
as a known anticancer drug for effects on two cell lines: Caco-2, colon carcinoma cells, and mouse normal fibroblasts
(L929). Cytotoxicity of 50, 100, 200, 400 and 800 μg/ml of Camellia sinensis extract was evaluated by MTT assay and
aquaporin 5 (AQP5), detected as a biomarker for surviving cells using immunofluorescence microscopy. Results: MTT
assays with hydroalcoholic extract of Camellia sinensis showed considerable inhibition of growth of Caco-2 cells,
significant at 800 μg/ml (P<0.05), with little effect on L929 cells. Levels of aquaporin 5 protein decreased in Caco-2
cell culture following green tea extract treatment. Conclusion: According to the results of the current study, Camellia
sinensis is a medicinal plant with potent anticancer influence which might be specific.- انتشار مقاله: 09-11-1396
