  • The effects of washing and desinewing on the composition, fuctional properties, storage stability and texture of spent layer meat were investigated. Spent layer meat subjected to treatments involving water washing, bicarbonate washing and desinewing showed increases in moisture content and decreases in protein content, hydroxyproline content and heme pigment content. Increases in salt extractable protein content and water holding capacity and decreases in buffering capacity and emulsifying capacity were also observed. The 2-thiobarbituric acid values of washed and desinewed samples increased slowly during storage indicated the increase in storage stability compared to the control. Sample rolls prepared from bicarbonate washed and desinewed thigh and drumstick meats were scored by trained sensory panelists as less tough than the products made of ground thigh and drumstick meats.

  • Traditionally posterior shadowing is regarded as a malignant criterion in the evaluation of breast mass by sonogram. But on the basis of our clinical experiences of breast sonogram, we often met a breast mass without posterior shadowing later confirmed breast carcinoma through pathologic examination. For the focus of what character of pathologic breast tissue influence the posterior shadowing in breast sonogram, we analyzed retrospectively the sonographic findings of 26 histologically proven invasive ductal carcinomas. Even though invasive ductal carcinoma is the only one of the many breast cancers, it represents the greater part of breast malignancy. The posterior echo pattern was compared with various histologic characteristics, such as the amount of connective tissue, degree of elastosis, necrosis, gross circumscription, accompanying inflammation, histologic differentiation, and mitotic index. Nine breast masses (35%) demonstrated posterior echo shadowing, while 17 masses (65%) showed enhancement. The tumors with posterior echo shadowing had more abundant connective tissue, increased elastosis, and poorly demarcated margin (p<0.05). Other histologic characteristics are not influence in posterior shadowing with significant in stastically. On the basis of our study, the phenomenon of posterior shadowing by sonogram is difficult to accept as a specific criterion for malignancy. It is only a phenomenon influenced by the amount of connective tissue volume and elastosis.

  • 임프란트 식립을 필요로 하는 환자의 수평적 치조제 결손의 증대를 위해 골유도재생술과 병용한 bioactive glass (BG) $(Biogran^{(R)})$ 이식의 골재생 양상을 각기 다른 치유기간을 부여한 4명의 환자에서 평가하였다. 6, 8, 10, 18개월의 치유기간 후 임프란트 식립부위에서 조직절편을 채득하여 골재생을 조직계측학적으로 평가하였다. 임프란트 식립을 위한 surgical reentry시 모든 이식부위는 임상적으로 명확한 수평적 치조제 폭경의 증가를 관찰할 수 있었다. 하지만 조직학적 분석결과 BG는 불량한 골전도성을 나타내었다. 6, 8개월의 치유기간후, 이식부위에서 신생골이 거의 관찰되지 않았으며(2.5%이하), 이식부와 기존 골의 경계부위에서 BG particle에 대한 신생골 성장과 결합양상 또는 관찰할 수 없었다. 10개월의 치유기간후 기존 골조직으로부터 성장한 신생골의 BG particle과의 직접적인 접촉양상을 일부 관찰할 수 있었다. 이식부는 13.2%의 광물화된 신생골조직을 보였고, 대부분의 BG particle은 결체조직으로 둘러싸여 있었다. 18개월의 치유기간이 부여된 환자의 조직절편에서 신생골은 이식부의 10.7%를 차지하여 비교적 낮은 신생골 형성양을 나타내었고, 이식부에 존재하는 잔존BG particle은 대부분은 결체조직으로, 일부분에서 광물화된 골조직으로 둘러싸여 있었다. 6, 8, 10, 18개월에서 잔존 BG particle양은 전체 이식부 면적에 대해서 각기 22.3%, 26.5%, 30.7%, 18.7%로 나타났다. 본 증례보고는 비록 한정적인 4명의 환자에서의 조직계측학적 평가결과이지만, 수평적 치조제 결손의 증대를 위해 골유도재생술과 병용한 bioactive glass이식은 불량한 골전도성으로 인해 효과적인 골재생을 위한 이식재로서는 적절하지 않을 수 있음을 나타낸다.

  • Histological study of eel was carried out to determine the effect of drying on muscular tissue and fat movement. The results are as follows: (1) Changes of muscular tissue during drying may he divided into two stages early and late. In the early stage there was apparent dehydration of connective tissue while in the late stage muscle fibre dehydration appears to occur. (2) Movement of fat during drying depends upon division and contraction of the myocommata caused by inner structural changes. This phenomenon appeared to be more apparent in the late rather than the early drying stage.(3) After freeze-drying traces of ice crystals were detected around the muscle cells. These ice crystals remained even after rehydration. (4) When muscular tissue was heated the connective tissue melted while muscle fiber dehydrated and solidified.

  • Implant placement in the anterior region is performed in several stages, and harmonization of both hard and soft tissues is essential. In addition, adequate esthetic and functional evaluations are necessary in the process of transitioning from the provisional to the final prosthesis to attain patient satisfaction. Although gingiva can be molded in the anterior region, depression in the occlusal view can yield good results through the augmentation procedure. However, the harvesting of connective tissue from the palate is not suitable for various reasons, such as postoperative discomfort and intraoperative bleeding. Compared to the palatal area, the harvesting of connective tissue from the maxillary tuberosity can easily result in relatively thick tissue and quick healing of the donor site, thus proving to be a good modality for graft procedures. The purpose of this report is to examine the relevant evidence from previous studies and evaluate the process of soft tissue augmentation through a case presentation.

  • Salted and dried yellow corvenia(Pseudosciaena manchurica), so called 'Gul-bi', is one of nation-widely consuming fish foo::ls. It is suitable for a long term preservation and its pro-duce is also a great deal on sea food processing in this country. The texture of 'Gul-bi', however, have often appeared to be a delicate factor for the quality of the product. The loss or dislocation of fat in the tissue of the fish resulted by salting and drying is believed to profoundly relate to the texture of product. In this paper, the tissue of yellow corvenia and movement of fat were microscopically observed before salting, immediately after salting, and after drying and the results observed in the tissues dry salted, brine salted, and brine salted with the addition of BHA were compared. The cross section of yellow corvenia muscle showed that a distinctive border by connective tissue between white and red muscle could not be seen in general, and red muscle was surrounded by hypodermic fatty tissues. In the tissue of fresh yellow corvenia, the fat was mainly distributed in hypodermic fat layer which located under the corium while rarely distributed in white muscle. It was found that some parts of the fat in the tissue were permeated into intermuscular tissue passing through the connective tissues during salting. The result Was the same in both dry-salting and brine-salting tissue. However, the fat translocated into intermuscular tissues disappeared during drying process in the salted without BHA tissues whereas in BHA added tissue. This result suggested that BHA may take a role of multiple effect in translocation of fat in tissues as well as in retarding oxidation. In an advanced stage of salted and dehydration, the muscle fibers were ajoined together and then limits between muscle fibers already became indistinguishable. And the migrated fat into intermuscular tissue aggregated around the connective tissue and are apt to gradually to flow out from the muscular system through these tissues.

  • The definition of fascial spaces are latent spaces between fascial planes. If infections which spread from dental origin to soft tissue are mild, they are restricted by fascial planes. But, when infections are severe, fascial spaces are often used as a natural pathway which spread to the deep cervical region. If they are not treated at early stage, they may result in the fatal complications as followings; airway obstruction, septicemia, cerebral abscess, and thrombophlebitis etc. The early treatment of fascial space abscess is very important for young children. These case reports present the successful result of fascial space abscess treatment through intracanal drainage without surgical excision. It is proven that the treatment through intracanal drainage has some benefits to the surgical excision, which are as follows: 1) It is economic to the patients or their parents avoiding admission. 2) The treatment procedure is more simple. 3) Childrens can avoid the fearful environment.
