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.

The importance of milk for the growth and health of a newborn offspring is well known. Milkcontains immunoglobulin G (Ig G), Ig A, lactoperoxidase, lactoferin, cytokines, and growth factors.Osteopontin, one of the multifunctional proteins, is secreted by macrophages, T cel, and epithelial cells.bovine milk have not been clarified. The aim of this study was to observe the expression of osteopontin,in bovine milk during the lactation period or bovine mamary glands..Western blot analysis detected thatosteopontin was expressed in bovine milk whey and mamary glands. The expression level of osteopontinin colostrum whey was higher than those in early milk and mature milk whey. Immunohistochemistryshowed that osteopontin was detected in the glandular epithelium and epithelial cels of intralobular ductof mamary glands. These findings suggest that osteopontin transiently shows high expression in colostrumand plays a potential role in the immunological development of breast-fed calves.

The localizations and morphological characteristics of immunoreactive cells for prolactin(PRL) and growth hormone(GH) antisera were studied with double immunohistochemistry in the adenohypophysis of the Korean native goat. PRL immunoreactive cells(mammotropes) and GH immunoreactive cells(somatotropes) were present in the pars distalis and pars tuberalis, but not in the pars intermedia. A few cells were stained with both PRL and GH antisera (somatomammotropes). The possessional percentages of mammotropes, somatotropes and somatomammotropes were 37.0%, 32.6%, 1.0% in females and 35.6%, 32.6%, 1.1% in males, respectively. Mammotropes were oval or round in shape, and $10{\sim}20{\mu}m{\times}17{\sim}25{\mu}m$ in size. These cells were distributed throughout the pars distalis, but were more abundant on the dorsal part adjacent to the hypophyseal cavity and along the lateral and ventral peripheral regions. Somatotropes were elliptical, triangular or polygonal in shape, and $8{\sim}17{\mu}m{\times}17{\sim}18{\mu}m$ in size. The distribution pattern of somatotropes was similar to that of mammotropes. Some somatomammotropes were intercalated between clusters of mammotropes while the others were dispersed independently among the secretory cells.

Breast tissue is composed of skin, mammary gland(including lactiferous duct), subcutaneous fat layer. The anatomical position is on the anterior chest wall(the outside of the chest cavity) but not on the inside of the thorax. Therefore, when the internal organs in the thoracic cavity are defined and expressed as 'organs' and the internal organs of each are labeled for a long time, for the breast located outside the thoracic cavity, it is thought that there is considerable difficulty in defining and recognizing the breast tissue as organs. For this reason, it is necessary to discourage the controversy over whether or not the breast is contained in the chest(or intra-thoracic cavity). In order to completely exclude it, it is assumed that the "chest-abdomen" can be called the "intra-thoraxic or intra-abdominal." But it is difficult to change the terms in various laws and regulations, I think that it would be necessary to insert only the clue clause "Breasts are excluded" in the detailed criteria for grading. In order to include it, it is necessary to change the terms of the ordinance or to say that the breast is exceptionally included.
