a2-year-old cachectic cross-breed gelding was admitted toveterinary teaching hospital of university of tehran followingthe onset of a marked respiratory distress, coughing and ventraledema. clinical examinations indicated harsh respiratory andexpiratory sounds as well as jugular vein distention. therespiratory and heart rates were 35/min and 60 bpm, respectively.agrade iii/iv pansystolic murmur...

OBJECTIVE To evaluate the short- and mid-term effects of percutaneous mitral balloon valvuloplasty (PMBV) on right ventricular functions in mitral stenosis. METHODS A prospective study was conducted in 61 patients who had mitral stenosis in normal sinus rhythm (68% female, age: 42±11-16 years). Right ventricular functions were measured before, immediately after, and at 3 months and 1 year aft...

Background: Increasing respiratory problems in youngsters, due to lifestyle and eating habits, have raised an alarming situation. To combat such health hazards, interest has peaked in the investigation of body mass index (anthropometric index) and its impact on pulmonary functions. Objectives: Aim of this study was to analyze relationship between pulmonary functions and body mass index (BMI) of...

Pulmonary surfactant is a complex and highly surface active material composed of lipids and proteins which is found in the fluid lining the alveolar surface of the lungs. Surfactant prevents alveolar collapse at low lung volume, and preserves bronchiolar patency during normal and forced respiration (biophysical functions). In addition, it is involved in the protection of the lungs from injuries...

[Purpose] The purpose of this study is to examine changes in pulmonary functions in relation to the sleeping positions of the experimental subjects. [Subjects and Methods] The subjects for this study were twenty randomly selected males and females from K University. Measurements were taken in the supine position at three different pillow heights: 0 cm, 5 cm, and 10 cm. Pulmonary functions (vita...

Background and Aims Thoracic paravertebral block (TPB) is one of the effective methods for management of post-operative pain in thoracic surgeries. The aim of the study was to evaluate effectiveness of addition of dexmedetomidine to paravertebral block with bupivacaine in improving the postoperative pain relief and pulmonary functions in patients undergoing thoracic surgeries. Methods A prosp...

American hantaviruses cause a highly lethal acute pulmonary edema termed hantavirus pulmonary syndrome (HPS). Hantaviruses nonlytically infect endothelial cells and cause dramatic changes in barrier functions of the endothelium without disrupting the endothelium. Instead hantaviruses cause changes in the function of infected endothelial cells that normally regulate fluid barrier functions of ca...

Arachidonic acid metabolites of the cyclooxygenase and lipoxygenase pathways have a variety of important lung functions. Recent observations indicate that cytochrome P-450 (P-450) monooxygenases are also expressed in the lung, localized to specific pulmonary cell types (e.g., epithelium, endothelium, and smooth muscle), and may modulate critical lung functions. This review summarizes recent dat...

conclusions ipah is associated with subclinical hypothyroidism and low patient functional capacity, and is more common in rv failure. results in this research, 84.8% of the participants were women. the mean pap was 51.6 mmhg (31-87) and mean thyroid stimulating hormone (tsh) level was 4.2 miu/ml (0.7 - 10). subclinical hypothyroidism was detected in 26 patients (49.1%). there were significant c...

conclusions we observed acceptable results regarding both efficacy and safety with 62.5 mg of bosentan, twice daily in this group of patients. further clinical trials investigating pah with lower dosages of bosentan may be warranted. results no adverse drug reaction was observed during the follow-up. clinical worsening occurred in six (14%) patients, at least one year after treatment, two of th...
