Bacteriological results from microscopic and cultural examinations of morning and 24 h sputum were compared in an attempt to optimize the diagnosis of bacterial exacerbations of chronic bronchitis. Twelve patients collected sputum randomly on two consecutive days, either fresh morning sputum (3 h sputum) first, followed by 24 h sputum or vice-versa. Sputa were washed three times in 0.9% NaCl an...

Background: Achievement the new biocompatible wound dressing is one of the attractive areas of research. Objective: The present study attempts to examine the healing effects of the alginate - Persian mannaplant extract in the induced rat wounds. Methods: After culturing and detecting of the Pseudomonas aeroginosa strains by phenotyping and genotyping methods, the produced alginate was extra...

Biological approximations, which are universal for diverse species, are well known. With no other experimental data, their invariance to transformations from one species to another yields exact conservation (with respect to biological diversity and evolutionary history) laws, which are inconsistent with known physics and unique for self-organized live systems. The laws predict two and only two ...

INTRODUCTION Atrioventricular node (AVN) contusion usually results in cardiogenic shock and arrhythmia and is a rare but fatal condition. The condition is difficult to diagnose and easily overlooked because it develops rapidly and is asymptomatic. We here report 3 cases that demonstrate blunt chest impact and hemorrhages of the posterior atrioventricular junction, eventually result in death. ...

OBJECTIVES Although it is widely accepted that academic examinations are accompanied by a cortisol increase, some recent studies reported either no effect or even a decline of the cortisol level. To reevaluate these discrepancies, we investigated whether personality traits predict the cortisol response upon academic examinations. SETTING AND DESIGN Nineteen male and female adolescent pupils (...

A test drug (Lipistat) comprising of equal-proportions of extracts of Terminalia arjuna, Inula racemosa Hook, latex of Commiphora mukul, in three different doses (225 mg/kg; 350 mg/kg; 450 mg/kg) were administered orally daily for 6 days a week for 60 days in rats. Thereafter, the rats were subjected to isoproterenol (ISO) induced (85 mg/kg, s.c. for 2 days) myocardial necrosis. Gross and micro...

The present study investigated the structure of the dorsal lingual surface tongue of the toad, Bufo bufo habitat in the west of Iran. The tongue of the toad contains two types of lingual papillae; fungiform papillae and filiform papillae. The fungiform papillae are usually scattered among the filiform papillae and are believed to function in gustation and in the secretion of salivary fluid. Lig...

An 82-year-old woman with type 2 diabetes had been treated with recombinant human insulin for 16 years. She developed large swellings in both sides of her lower abdomen. The masses were soft, painless, and located around her insulin injection sites. Based on the history and clinical features, a diagnosis of insulin-induced lipohypertrophy was made. Total resection revealed that the lesions were...
