OBJECTIVES In this study, we evaluated the efficacy of nebulized bovine pulmonary surfactant on experimentally induced otitis media with effusion (OME) in guinea pigs. METHODS Twenty guinea pigs were divided into three groups. Four untreated animals served as normal controls. Experimental OME was established in both ears of the remaining 16 animals by a transbullar injection of 10 microL of P...

kocho and bula are fermented product of enset (ensete ventricosum). it is the staple food for 20 million people in ethiopia. the aim of study was to isolate, identify and characterize yeast species from fermented kocho and bulla by using biolog micro station. 300 kocho samples were collected from angacha district. 0.1ml of serially diluted samples were streaked on yeast pepton dextrose agar and...

BACKGROUND Coexistence of adenocarcinoma and mantle cell lymphoma in the same or different anatomical sites is extremely rare. We present a case of incidental discovery of primary lung adenocarcinoma and mantle cell lymphoma involving the pleura, during an axillary thoracotomy performed for a benign condition. CASE PRESENTATION A 73-year old male underwent bullectomy and apical pleurectomy fo...

Since the research work of Fischer-Wasels by anatomic methods, we know that in the pathogenesis of so-called idiopathic spontaneous pneumothorax certain bullae, situated on the surface of the lung, play an important part. Later our concept was further extended by pleural endoscopy which made possible not only exact diagnosis, but also effective therapy. We learned by means of biopsy that the bu...

OBJECTIVES We examined histopathologic and anatomical features of the guinea pig temporal bone and evaluated the differences and similarities with respect to the human ear. STUDY DESIGN Seventeen adult guinea pigs were deeply anesthetized with pentobarbital and then decapitated. Each temporal bone was removed and fixed in 10% formaldehyde for a week, then decalcified in 10% formic acid for th...

Introduction The anterior ethmoidal artery (AEA) is one of the main arteries that supply both the nasal mucosa and the ethmoid sinuses. The AEA shows variability regarding its distance from adjacent structures. Several studies have developed techniques to identify the AEA. Objective This study aimed to compare the measurements from the AEA to the ethmoid bulla and to the frontal beak by using c...

PURPOSE To evaluate tympanic bulla healing after experimental ventral osteotomy in cats. METHODS Twenty adult cats were submitted to unilateral ventral bulla osteotomy and divided into two groups: cats of A1 group (n=10) were euthanized at 8 weeks and cats of A2 group (n=10), at 16 weeks postoperative. RESULTS Signs of Horner's syndrome or damage to the inner ear were not found. Open-mouth ...

Common middle ear diseases may affect bone behavior in the middle ear air cell system. To understand this pathologic pneumatization, the normal development of bone in the middle ear should be investigated. The objective of this study was to analyze gene expression of bone-related signaling factors and gene sets in the developing middle ear. Microarray technology was used to identify bone-relate...

Patients with severe emphysema have a higher risk of developing lung cancer, and their surgical risk increases when emphysema is accompanied by a giant bulla. Here, we describe a patient who had an emphysematous giant bulla in the right upper lobe that was treated with an endobronchial valve placement. Subsequently, a cancerous lesion on the contralateral lung was successfully removed by lobect...
