  • Even if we can recover the function of mastication, pronunciation and esthetic using the fixed or removable prosthesis in the loss of teeth or hard tissue in the oral cavity, we use several kinds of implants in order to solve the problem which can be occured when we can't install the denture because of excessive bone resolution or psychlogical affairs. At present Titanium implant plays a major role in this field and has osseointegrated. And the study on the modern material is going on, that result in developing and using the implant which is coated with HA, bone induced material. In this, I studied histologically the change of the bone tissue which is occured when three kinds of HA coated implants. Such as Integral, Sustain, Biovent implanted into mandible of dog and got a 8-weeks healing period. I got the conclusion as follows: 1. Most of the implant which is covered with serveral kinds of HA coating implant in bone after 8 weeks being implanted and has osseointegrated, partially converted into the connective tissue. 2. Biovent formed the connective tissue in the perforated area of inferior alveolar canal and has osseointegrated.

  • This study investigated the use of grammatical morphemes (substantive morphemes and connective endings) of Korean speaking children with and without language impairment (LI). Participants were two children (ages 5;11 and 6;2) with SLI (specific language impairment), two LD (language delay) children (ages 6;3 and 6;5) with 70-84 range on a performance-IQ test, and two children (ages 5;7 and 6;1) with ND (normal development). Spontaneous language samples were elicited by play activities and story generation. A total of 8,059 (M=I,343, ranged 966-1,659) intelligible and nonimitative utterances were analyzed by the KCLA 2.0 (Korean Computerized Language Analysis 2.0) program for substantive morphemes and connective endings. The findings of this study were as follows; (1) The Korean speaking children with LI including SLI demonstrated less uses of grammatical morphemes than ND children. (2) Few differences were found between LI and ND children in the use of the grammatical morpheme types. (3) LI children produced significantly higher percentage of grammatical morpheme errors in spontaneous speech than ND children. (4) Few differences were found between SLI and LD children in degrees of the use and the error of grammatical morphemes.

  • The appearance and function of corpora lutea(CL) with a central cavity in the ovaries of Korean Native Cattle (KNC) were investigated endocrinologically and histochemically. The CL were enucleated from KNC ovaries within 2~3 hrs local slaughter house and classified with central cavity CL or not. Enzymatically dispersed luteal cell (1$\times$106 live cell/ml of Dulbecco's Modified Eagle Media) with or without cavity of CL cultured at 37$^{\circ}C$ in a humidified incubation (5% CO2 : 95% air) for 72hr. A central cavity in the CL of KNC was found in 58.8% of CL-1, 34.9% of CL 2, 39.1% of CL-3, and 11.1% of CL-4, respectively. There were no significant difference between protein content of CL with and without a central cavity. Mean progesterone secretion after 36h of in vitro luteal cell culture were significantly (p<0.05) higher in CL with central cavity than without cavity. However, the luteal cavitic wall was composed of the connective tissue band of the reticular and collagen fibers and then these connective tissue band extended into the CL with cavity. These results suggest that the central cavity of CL may be caused infertility in KNC.

  • General massage and sports massage techniques are kneading, petrisage and tappotment. These will be improve physiological reaction. Connective tissue massage is a reflex zone massage in the subcutaneous tissues. These are superficial and deeper fascia, intermuscular septa, blood vessel, perinerve tissue. It is frame work on organs in human-being, Therefore, abnormality of there tissues are a pathologic change of the organs. The pathologic changes are fined with visible investigation, manual investigation and stroking investigation on the reflex zone. The stroking on the reflex zone is the treatment also. Stroking methods are depend upon tissues and area. Short strokings are directed at approximately right angles against bone, muscular or facial board. Long strokings are very often follow the original cleavage lines. The back is divided for treatment purposes into sections. There are basic section, thoracic section and cervical section.

  • Purpose: A laterally positioned flap (LPF) combined with a subepithelial connective tissue graft (SCTG) is one of the conventional approaches for resolving gingival recession defects, with the advantages of flap flexibility and extended coverage of the tissue graft. However, thus far, evidence is lacking for the use of this technique for the treatment of advanced gingival recession defects. This report discusses three Miller class III cases with interproximal bone loss and wide and deep defects treated with a combination procedure of a modified laterally positioned flap (mLPF) and SCTG. Methods: mLPF combined with SCTG was performed for each case. The defect size and the degree of hypersensitivity at baseline and the final appointment in each case were documented. Results: The three cases had a mean initial defect of $7.7{\pm}1.5mm$ and a mean residual defect of $1.7{\pm}1mm$ at the 6-, 3-, and 36-month follow-up, respectively, after the root coverage surgery. The symptom of hypersensitivity was improved, and the patients were satisfied with the clinical outcomes. Conclusions: The results demonstrated that the combination of mLPF with SCTG is promising for treating these advanced cases with respect to obtaining the expected root coverage with the gingival tissue.

  • Ehlers-Danlos syndrome (EDS) type IV is characterized by its clinical manifestations, which are easy bruising, thin skin with visible veins, and rupture of arteries, uterus, or intestines. Arterial complications are the leading cause of death in vascular EDS because they are unpredictable and surgical repair is difficult due to tissue fragility. The authors report a case presented with cervical radiculopathy due to a segmental fusiform aneurysm of the cervical vertebral artery. Transfemoral cerebral angiography (TFCA) was done to verify the aneurysmal dilatation. However, during TFCA, bleeding at the puncture site was not controlled, skin and underlying muscle was disrupted and profound bleeding occurred during manual compression after femoral catheter removal. Accordingly, surgical repair of the injured femoral artery was performed. At this time it was possible to diagnose it as an EDS with fusiform aneurysm on cervical vertebral artery. Particularly, cervical fusiform aneurysm is rare condition, and therefore, connective tissue disorder must be considered in such cases. If connective tissue disorder is suspected, the authors suggest that a noninvasive imaging modality, such as, high quality computed tomography angiography, be used to evaluate the vascular lesion to avoid potential arterial complications.

  • The present paper deals with mortality and pathogenetic investigation of the oysters Crassostrea gigas cultured by tile coventional bamboo and hanging method in Kimhae and Koje-Do in 1969. The results of the investigation may be summarized as follows: 1. Mortality of the oysters by the bamboo method in Kimhae was $9.5\%$ in June, $10.2\%$ In July, $12.3\%$ in August and $12.1\%$ in September, respectively, 2. Mortality of the oysters cultured by the hanging method in Koje-Do was $2.4\%$ in June, $2.9\%$ in July, $30.7\%$ in October, $37.3\%$ in November and $30.0\%$ in December, respectively 3. The diseased oysters had severe inflammation, necrosis and multiple abscess in the epithelia of stomach, mid-gut, digestive tubules, blood vessels and gonads, mucous membrane and surrounding tissue. 4. From August gram negative bacteria were found in the nodules of connective tissue and multiple abscess of the diseased oysters. Particularly the connective tissue of the diseased oysters contained more bacteria than epithelia. 5. Since the bacteria are less abundant in the region of digenerated tissue, mortality of the oysters is not caused only by the infectious bacteria but seems that is also caused by other environmental factors such as extreme temperatures and salinities.

  • Mast cells play an important role in allergic inflammation by releasing their bioactive mediators. The function of mast cells is enhanced by stimulation because of the induction of specific genes and their products. While many inducible genes have been elucidated, we speculated that a significant number of genes remain to be identified. Thus, we applied differential display (dd) PCR to establish a profile of the induced genes in bone marrow-derived mast cells (BMMCs) after they were co-cultured with 3T3 fibroblasts. To date, 150 cDNA fragments from the connective-type mast cells (CTMCs) were amplified. Among them, thirty cDNA fragments were reamplified for cloning and sequencing. The ddPCR strategy revealed that serine proteases were the most abundant genes among the sequenced clones induced during the maturation. Additionally, unknown genes from the co-culture of BMMCs with 3T3 fibroblasts were identified. We confirmed their induction in the CTMCs by Northern blot analysis and RT-PCR. Characterization of these induced genes during the maturation processes will provide insight into the functions of mast cells.

  • A study of pulmonary diseases in the slaughtered cattle (n = 125) of Mymensingh town was conducted to study pathological findings using the standard methods from September 2001 through April 2002. The pulmonary lesions observed in this study included congestion, emphysema, anthracosis, pleuritis abscess and hemorrhage. The histopathological findings of congestion were characterized by hemorrhage, a large number of leukocytes infiltration in the lumen of the alveoli, bronchitis, bronchiolitis, proliferation of fibrous connective tissue and hyperplasia of bronchiolar epithelia. Histopathologically, emphysema was identified by the distended alveoli with thin and atrophied alveolar walls. In anthracosis, carbon particles were found in stroma and alveolar lumen. In pleuritic lesions, there was a proliferation of fibrous connective tissue along with the infiltration of mononuclear reactive cells. Abscesses were characteristic of the accumulation of neutrophils surrounded by immature fibroblasts forming a capsule like structure.

  • Sertoli cell tumor (SCT) of the testicle arises from the supporting cells within the seminiferous tubules. SCT is common in dogs, especially in cryptorchid testicles, but also has been reported in the stallion, ram, cat, and bull. Sertoli cell tumor sample was collected from 7-years male german shepherd. In this study, SCT arose from one testicle. Sample size is approximately 1.7 cm in diameter and it has a round form. In the microscopic, cells within the tumor variably resemble Sertoli cells (SCs) that normally populate the seminiferous tubules and interstitial area. There is abundant stroma of dense, mature fibrous connective tissue in SCT. In the immunohistochemical staining, cytokeratin AE1/AE3 was not expressed in the control and SCT. S-100 protein was expressed by SCs, germ cells and fibrous connective tissue of SCT. Melan A was expressed by leydig cells (LCs) of SCT. A study by using S-100 and melan A in canine SCT was almost never carried out. S-100 and melans A is considered to suggest for diagnosis and pathogenesis of canine SCTs. Inhibin-alpha and Vimentin were well known as the marekers of SCTs. Also, they were expressed by Sertoli cells and LSs of SCT in this study.
