  • Somatotropes, mammotropes and somatomammotropes of the Korean native goat hypophysis were studied by double immunoelectron microscopy using antisera to growth hormone(GH) and prolactin(PRL), and protein A-gold particles of different sizes. Mammotropes were round or oval in shape, and contained round and electron dense secretory granules. The size of secretory granules was variable from 460nm to 680nm in diameter. Somatotropes were elliptical or triangular in shape and the oval nucei were located eccentrically at the periphery of the cell. Secretory granules of the cell were oval in shape and clearly distinguished from round granules of mammotropes. The size of granules was 320~680nm in diameter, smaller than that of mammotropes. Somatomammotropes contained round or oval secretory granules. The granules had intermediate size between somatotropes and mammotropes. Some of granules contained both GH and PRL, while the others contained only one of them.

  • Nitric oxide (NO) occurs in various types of cells in the central nervous system. We studied the distribution and morphology of neuronal nitric oxide synthase (NOS)-containing neurons in the visual cortex of mouse and rabbit with antibody immunocytochemistry. We also compared this labeling to that of calbindin D28K, calretinin, and parvalbumin. Staining for NOS was seen both in the specific layers and in selective cell types. The densest concentration of intense anti-NOS immunoreactive (IR) neurons was found in layer VI, while the weak anti-NOS-IR neurons were found in layer II/III in both animals. The NOS-IR neurons varied in morphology. The large majority of NOS-IR neurons were round or oval cells with many dendrites coursing in all directions. Two-color immunofluorescence revealed that only 16.7% of the NOS-IR cells were double-labeled with calbindin D28K in the mouse visual cortex, while more than half (51.7%) of the NOS-IR cells were double-labeled with calretinin and 25.0% of the NOS-IR cells were double-labeled with parvalbumin in mouse. By contrast, 92.4% of the NOS-IR neurons expressed calbindin D28K while only 2.5% of the NOS-IR neurons expressed calretinin in the rabbit visual cortex. In contrast with the mouse, none of the NOS-IR cells in the rabbit visual cortex were double-labeled with parvalbumin. The results indicate that neurons in the visual cortex of both animals express NOS in specific layers and cell types, which do not correlate with the expression of calbindin D28K, calretinin or parvalbumin between the two animals.

  • Arterial switch operation for repair of nineteen cases of transposition of the great arteries associated with ventricular septal defect and three cases with double outlet right ventricle with subpulmonary ventricular septal defect[Taussig-Bing type DORV] was performed from November 1987 to September 1990 at the Seoul National University Children`s Hospital. Sixteen of them were under six months of age, and three were under one year of age with body weight ranged from three to fourteen kilograms. Preoperative cardiac catheterization was done in eighteen patients, in which the pressure of the left ventricle was greater than 70% of the right ventricle in all but one. Patent ductus was associated in thirteen cases[68.4%] of TGA+VSD, and atrial septal defect or patent oval foramen was in sixteen cases. Four atrial septostomy, one modified Blalock- Taussig shunt, one pulmonary artery banding, one coarctoplasty using subclavian arterial flap, were perfomed before arterial switch operation. There were five hospital deaths, all in the. patients with transposition of the great arteries with ventricular septal defect[overall mortality rate 22.7%]. Lecompte Maneuver was used in all patients, and in all patient the U-shaped flap of coronary arteries were transposed to V-shaped cleavage created in the neoaorta. Arterial defect in the neopulmonary artery was covered with 0.0625% Glutaraldehyde fixed autogenous pericardium There have been no late deaths, Postoperative cardiac catheterization and angiocardiogram in four patients has revealed no stenosis in the neopulmonary artery or neoaorta with reasonable P[RV/LV], Anatomic correction for transposition and double outlet right ventricle with subpulmonary ventricular septal defect would seem to be a good operative alternative to intraatrial switch procedures, with the advantage of incorporating the left ventricle to systemic circulation.

  • A 7-year-old female Shih Tzu dog with lots of masses in the whole mammary gland was presented to the surgery department of the Veterinary Teaching Hospital in the Cheju National University. After surgical excision, all mammary samples were referred to Pathology Department of Veterinary Medicine. Grossly, masses were measuring up to $6.5{\times}4{\times}1cm$ and on cut surface of masses in right 1st, 3rd, 4th, 5th and left 1st, 3rd, 4th, 5th mammary masses were well delineated and firm, sulphur yellow, solid round to oval shape. Microscopically, most neoplastic sweat glands were severely proliferated in dermis and subcutis. Most tubules were lined by round to oval shaped epithelium with eosinophilic cytoplasm, hyperchromatic nuclei with high mitotic figures and severe central necrosis. The neoplastic epithelium also had PAS-positive diastase-resistant cytoplasmic granules, but negative with Perls iron stain. The left 2nd mass was well delineated, and had several dark brown areas and yellowish white glittered areas. Mass was well circumscribed with dense connective tissue. Neoplastic areas contained irregular sized mammary gland with papillary grown luminal epithelial cells in single or double cells layer with mitotic figures and small amounts of proliferated myoepithelial cells. Proliferated myoepithelial cells also produced slightly basophilic mucinous materials. Based on the gross, histopathologic and special staining characteristics, this dog was diagnosed as 90% of apocrine sweat gland aenocarcinoma and 10% mammary. complex adenomas in mammary masses. In our best knowledge, this is the first report for concurrent occurrence of apocrine sweat gland adenocarcinoma and mammary gland complex adenoma in mammary masses of the same dog.

  • Many antibiotic monographs cite the induction of vaginal infections as a possible side effect. Invariably, this is believed to be due to Candide albicans, and empirical therapy is given. However, recent studies raise the question of the extent to which yeast do infect the host after antibiotic use. A double-blind, randomized, placebo-controlled study was undertaken on female patients to determine how many yeast infections occurred following 10 days antibiotic use. In addition, the study was designed to examine whether oval use of probiotic lactobacilli can reduce the risk of vaginal infection. Twenty four patients diagnosed with respiratory, oval or throat infections received one of several types of antibiotic for 10 days, and two capsules containing 10$^{9}$ dried Lactobacillus rhamnosus GR-1 and L. fermentum RC-14 from the day of commencement of antibiotic therapy for 21 days. The most commonly prescribed antibiotic was biaxin (clarithromycin). All but one patient had lactobacilli in the vagina upon entry to the study, and none developed yeast vaginitis or diarrhea during treatment or 20 days after completion of antibiotics. The mean Nugent score was higher in the placebo than the lactobacilli group (4.1 versus 2.4), and three cases of bacterial vaginosis arose (25 % incidence compared to 0% in the lactobacilli group) in the placebo group (2 receiving cefuroxime, 1 on biaxin). The study suggested that current antibiotic use is not necessarily associated with either diarrhea or yeast infection, as is often surmised. Nevertheless, daily use of probiotics was safe and could potentially reduce the risk of patients developing bacterial vaginosis after antibiotic use.

  • The history of tall buildings begins in 1853with the development of elevators. After the Industrial Revolution of the 18th century, the development of high-rise buildings will be carried out in earnest as a means to efficiently use the limited land of cities. The development, which began around Chicago, extended over a long period of time to Asia, maximizing the high competition. However, in the 2000s, not only was it high due to the development of construction and digital technology, but it also became competitive in eco-friendly elements and unstructured forms. High-rise building plans that have gained elemental and morphological diversity are completed by the interrelationships of various plans. Among them, it is important that the core plan has a reasonable approach from the initial planning stage as the basis for the vertical copper plan linking vertically-intensive functions. The cores should be designed to be clear and adequately responsive to changes in the shape of the building. This study aims to provide designers with a reasonable understanding of core planning by identifying core characteristics of irregular high-rise. In particular, we want to analyze the shape of the ground layer core and the relationship between the area and components of the ground layer core. The analysis results are as follows, classified according to the type or use of the building. Of the atypical forms composed of double bending, the TAPER-Curve and TWIST forms are the most distributed, and the plane and core shapes of the ground floor are the most commonly used. Based on the analysis of the validity of the ground floor cores by shape of the cores, the most commonly used forms for core shapes in the planning of the atypical high-rise are square, circular and Oval, and the most efficient oval cores and relatively inefficient ones when planned.

  • This paper introduces a system to machine micro-sized patterns effectively on surface based on micro-milling process using tools with simultaneous rotation and oscillation, oscillation micro milling. To review the effectiveness of proposed concept, we integrated a micro-spindle supported by active magnetic bearings with a precision 3-axis air bearing stage using double-wedge mechanism, and tested this oscillation milling. Two types of oscillation milling were tested, which are linear oscillation milling with a flat end mill and elliptical oscillation milling with a ball end mill with 0.3 mm of diameter. The spindle was rotating 110 krpm and workpiece was moving constant speed of 2~8 mm/sec during the oscillation milling. As the results, multiple oval shape dimples were generated in regular spacing, and the variation of elliptical motion made different shapes of patterns. The results showed that proposed oscillation milling can be successfully used for machining repeated micro-patterns.

  • Cutaneous leiomyomas (leiomyosarcomas) are smooth muscle tumors that occur single or as multiple lesions. They usually arise from the arrector pili muscles (piloleiomyomas) and less commonly from the muscle of veins (angioleiomyomas). This report describes histologic and immunohistochemical features of one cutaneous piloleiomyoma and two angioleiomyosarcomas. Three 7-12-year-old female dogs were presented with single or double cutaneous nodules. Histologically, the neoplastic masses were composed of densely or loosely arranged interlacing bundles. The neoplastic cells were ovoid to elongate, and had eosinophilic cytoplasms and perinuclear cytoplasmic vacuolation. Nuclei were central to eccentric, cigar shaped, oval to elongate. In two cases, high mitotic index in high power field, multifocal necrosis and local invasion were also noted. Masson's trichrome and van Gieson staining revealed muscle origin tumors in these cases. Immunohistochemically, the tumor cells were strongly positive for smooth muscle actin. In our best knowledge, this is the first report of cutaneous smooth muscle tumors in dogs in Korea.
