Streszczenie angielskie:
Background: Experimental studies have shown that doxofylline is endowed with a remarkable bronchodilator activity with less extra-respiratory effects than theophylline. This trail was designed to compare the efficacy and safety of doxofylline, theophylline, and placebo in patients with chronic reversible bronchial asthma. Material/Methods: Three hundred forty-six patietns were randomly assigned to a 12-week oral treatment with either doxofylline 400 mg t.i.d. (high dose), doxofylline 200 mg t.i.d. (low dose), theophylline 250 mg t.i.d. (active control) or placebo. Pulmonary function tests (PFTs) were performed biweekly. Patients kept records of peak flow meter (PFM) measurements, asthma attack rate and beta-2-agonist use (albuterol). Results: Changes in FEV1 2 hours after the administration of treatments versus baseline exhibited statistically significant differences between doxofylline 400 mg t.i.d. and placebo and between theophylline and placebo. Similar differences were monitored on the other variables (FVC, PFER, FEF25-75 p.c. Asthma attack rate and use of albuterol decreased remarkably with doxofylline 400 mg t.i.d. and theophylline. There were few statistically significant differences between doxofylline 200 mg t.i.d. and placebo. Significantly more patients had to interrupt treatment because of adverse events under theophylline than under doxofylline 400 mg t.i.d. (p=0.001). With doxofylline 400 mg t.i.d., the number of patietns treated to spare one dropout due to theophylline was 5. Conslusion: This study provides evidence that doxofylline 400 mg t.i.d. is an effective treatment for relieving airway obstruction and displays a better safety profile with respect to theophylline 250 mg t.i.d. with a favorable risk-to-benefit ratio.

Streszczenie angielskie:
Background: A number of molecular changes observed by varied conventional methods, including loss of heterzygosity (LOH) on chromosome 3, have been associated with primary lung cancer. To further define the locus of chromosome 3p allele loss in lung cancer, we performed LOH study by using innovative laser capture microdissection and WAVE DNA Fragment Analysis. Mateiral/Methods: Thirty-eight paired specimens from patients with adenocarcinoma of the lung were used for this study. Formalin-fixed, paraffin-embedded tissue from normal stromal cells or lymphocytes and adenocarcinoma were collected using laser capture microdissection. DNA was extracted and amplified by PCR using six polymorphic DNA markers for chromosome 3. PCR products were analyzed by both gel electrophoresis and WAVE DNA Fragment Analysis. Results: LOH at 3p22-24 was found in tumor cells from twelve out of thirty-eight patients (32 p.c.) when analyzed by WAVE DNA Fragment Analysis and LOH was found in tumor cells from nine out of thirty-eight patients (23 p.c.) when analyzed by gel electrophoresis. LOH was found in normal control from one out of thirty-eight patients. Conclusions: 1. Our results suggest putative tumor suppressor gene(s) is present in a region at 3p22-24, which may play a role in carcinogenesis of lung cancer. 2. Laser capture microdissection is essential tool for defined LOH studies. 3. WAVE DNA Fragment Analysis is an accurate, sensitive and automated tool for analysis of DNA fragments.
