  • The cholesteatoma is usually associated with chronic purulent otitis media and destroys the surrounding structures and may cause dangerous complications. The cholesteatoma with a positive fistula sign may be observed occasionally, if a softened area is formed in the bony capsule over a semicircular canal which exposed the membranous structure of the canal. Recently, the authors have experienced a case of cholesteatoma combined with labyrin thine fistula in a 22-year old male patient. We present this case with a brief review of the literatures.

  • Tolerance of Mycobacterium sp. against organic solvents has been induced for the cholesterol side chain degradation by adding chemicals associated with synthesis of fatty acids or alcohols. Biotin of 300 .mu.g/1 and 0.5% aqueous ethanol solution were optima for the enhancement of ethanol tolerance of the microorganism. The induction of ethanol tolerance by biotin was found to be due to increase of degree of unsaturation of the fatty acids in membranous phospholipid of the cell, especially due to increase of oleic acid content. However when 0.5% of ethanol was added for the ethanol tolerance induction, there was an ambiguous correlation between ethanol tolerance and degree of unsaturation of the fatty acids, in spite of the fact that the induction increased the content of unsaturated fatty acids. Addition of 0.5% of ethanol induced several ethanol shock proteins having molecular weight similar to that of heat shock proteins.

  • Objectives The purpose of this study is to report the effect of oriental demonstration treatment for episodic vertigo of Meniere's disease. Meniere's Disease characterized by recurrent prostrating episodic vertigo, nausea, vomiting, sensory hearing loss, tinnitus, and a feeling of fullness in the ear associated with generalized dilation of the membranous labyrinth (endolymphatic hydrops). The cause of Meniere's disease is unknown, and the pathophysiology is poorly understood. Methods We experienced one case of Meniere's disease treated with Asian medical treatment, acupuncture and herbal medication. 64-year-old female patient was diagnosed with Meniere's disease by western medical doctor. Methods: Saam acupuncture Sojangjungkyuk applied to the patient. Results After treatment her episodic vertigo, nausea, vomiting and endolymphatic hydrops were decreased but the level of tinnitus it was not improved as much as other symptoms. Conclusions Saam Acupuncture of Asian medical treatment could be safe and effective.

  • The esophageal atresia with tracheoesophageal fistula occurs approximately once in 3, 000 live births. In Korea, about 20 cases were reported with five successful surgical corrections. The atresia characteristically occurs at the level of, or just cephalad to, the carina and is associated with a tracheoesophageal fistula. In about 90% of the cases, the upper esophagus ends in a blind pouch, and the lower esophageal segment communicates with the trachea through the membranous posterior wall just above the carina. Many of the Infants with esophageal atresia have other congenital anomalies. The most common of these are congenital cardiac anomalies, imperforate anus, genitourinary malformations, and intestinal atresia. Recently we experienced four cases of esophageal atresia, of which three were Gross type C and one was type A. Two of them were treated by primary repair, and one [type A] was taken cervical esophagostomy and gastrostomy. The another was refused surgery.

  • During epididymal transit, mammalian sperm acquire selected proteins secreted by the epididymis. We previously showed that a disintegrin and metalloprotease (ADAM) 7 is expressed specifically in the epididymis and transferred to the sperm surface during epididymal transit. Here, we show that mouse ADAM7 secreted to the epididymal lumen is associated with membranous vesicles known as epididymosomes. Furthermore, we found that ADAM7 can be transferred directly from epididymal vesicles to sperm and that it is an integral plasma membrane protein in sperm. Thus, our study provides new information regarding the unique mode of secretion and interaction of ADAM7 during the epididymis-to-sperm transfer process.

  • A marine algal species was collected from Sacheonjin, Gangneung located on the eastern coast of Korea during a survey of marine algal flora. This alga shares the generic features of Membranoptera belonging to the subfamily Delesserioideae and is characterized by the presence of combined features of membranous, monostromatic thalli attached by a solid discoid holdfast, blades with a conspicuous terete stipe-like midrib and microscopic lateral veins, entire margins, irregularly alternate to dichotomous branching, and obtuse apices growing apically. In a phylogenetic tree based on rbcL sequences, the Korean alga nests in the same clade with M. alata from the eastern North Atlantic. The genetic distance between both the sequences within the clade was calculated as 0.0%. Based on the morphological and molecular analyses, this Korean species is identified as the generic type, M. alata. This is the first record in the list of Korean marine algal flora.

  • A marine red algal species was collected from Pyengdae-ri, Gujwa in Jeju, Korea during a survey of marine algal flora. This alga shares the generic features of Callophyllis(Gigartinales, Kallymeniaceae), and is characterized by erect and membranous thalli, branches dichotomously or trichotomoulsy divided, margin somewhat undulate or entire and tetrasporangia scattered irregularly in the cortex. In a phylogenetic tree based on rbc L sequences, the Korean alga nests in the same clade as C. mageshimensis originally described from Japan. The genetic distance between both sequences within the clade was 0.0-0.1%. Based on the morphological and molecular data, the alga was identified as Callophyllis mageshimensis. This is the first record of C. mageshimensis in Korean marine algal flora.

  • Atratoxin $B_1$ which was found to inhibit the growth of Candida albicans caused structural and morphological alteration of the cells. Increased accumulation of vesicles and membranous bodies in the cytoplasm, and alterations of the cell membrane and cell wall were most obvious. Sequential lytic events of the cells eventually resulted in complete disintegration of the cytoplasmic structures. These results suggested that atratoxin $B_1$ functioned by either blocking the biosynthetic step during cell wall synthesis, altering cell wall metabolism or dissolution of the cell organelles. These changes caused a progressive destruction of the cell wall leading to cell lysis.

  • The azygos vein sometimes merges abnormally across the right upper lobe of the lung and it hangs at the lower edge of a membranous septum, called the meso-azygos. The septum invaginates the lobe and makes a fissure. The smaller medial part of the right upper lobe is called an azygos lobe. A 16-year-old male patient was diagnosed with right-sided pneumothorax, and a closed thoracostomy was done in the emergency room. During elective wedge resection including the bulla, the meso-azygos, abnormal azygos vein, and azygos lobe were detected. We reviewed the computed tomography images and found that the azygos lobe had re-expanded laterally, not medially, to the meso-azygos after the closed thoracostomy in the emergency room. The patient had been diagnosed with left-sided pneumothorax a year ago, and no one noticed the azygos lobe at that time. We report the intraoperative findings and comparative images of a migratory azygos lobe.
