Accurate reproduction of intraoral tissue is essential in the fabrication of fixed prosthesis. This selection of impression material and method is very important. In this study, vinyl polysiloxane type impression material Panasil was used. Three impression methods ; one-step technique, individual tray technique, and individual tooth tray technique using the vinyl polysiloxane type bite registration material Futar Occlusion, were used to take horizontal and vertical impression. Improved stone models were fabricated. The amount of occlusal surface discrepaneies, interabutment distance discrepancies, amount of marginal defect were evaluated with the X-PLAN360d and photoscanning. The results were as follows. 1. There was no significant difference in occlusal surface according to the directions and techniques of impression taking. 2. There was no significant difference in interabutment distance discrepancies according to the directions and techniques of impression taking 3. There was no significant difference in marginal discrepancies according to the direction of impression taking but there was significant difference between one-step technique and individual tray technique, individual tooth tray technique (P<0.05). Taken together, these results suggest that individual tray technique and individual tooth tray technique are more accurate for impression taking than one-step technique.

BACKGROUND: The current recommendation of rescue breathing techniques in the infant is to blow both the nose and mouth of infants by caregiver's mouth but recent studies suggest some caregivers may have trouble sealing a infant's mouth and nose. The purpose of this study is to estimate the ability of mothers to create a seal to their infants for the provision of rescue breathing according to current recommendation. METHODS: Infants up to 1 year of age(n=98) and their mothers were enrolled from emergency department of Chonbuk National University Hospital. We measured the facial lengths of the infants and the width of mouth in their mothers and compared mouth widths of mothers with their infant's nose-to-mouth lengths. RESULTS: In infants between 0 to 6 months, Mother transverse lengths were significantly larger than mouth, nose and nose-to-mouth lengths of the infants. In infants between 7 to 12 months, Mother transverse lengths were significantly larger than mouth and nose lengths of the infants but there was no statistically significant difference between mother transverse lengths and nose-to-mouth lengths of infants. CONCLUSION: The finding indicate that the present recommendation to cover mouth and nose is partly not possible. We recommend that the mouth-to-nose ventilation of rescue breathing techniques for the infants who have respiratory arrest be taught to mothers.

We have studied the function of lymphokines on human tonsillar B cell prolifertion and differentiation. B cells were stimulated with Staphylococcus aureus Cowanl (SAC) or anti- bead. The followings showed the results of this study. 1) In B cell activation, SAC induced B cell DNA synthesis but anti-mubead did not. SAC could activate and proliferate B cells. Minimal number of B cells were required to proliferate effectively. 2) In B cell proliferation, SAC could proliferate B cell in the abscence of lymphokines. Exogenous IL-2 or IL-4 enhanced B cell proliferation. The roles of IL-2 were very important in B cell proliferation. The effect of IL-4 on the IL-2 induced B cell proliferation was inhibitory in SAC-B cells. IL-4 could enhance the proliferation of anti-mu bead activated B cells. 3) In B cell differentiation, IL-2 was a major factor to differentiate SAC activated B cells, but IL-4 did not. IL-6 had a synergistic effect on the differentiation. The results of this study showed that the different signal transduction mechanisms were involved in B cell proliferation and differentiation. The B cell resposes to lymphokine were different, and it is depend upon antigens or mitogens.

Mucoepidermoid carcinoma of lung are rare carcinoma arising from the submucosal glands tissue of the proximal tracheobronchial tree. The carcinoma can be divided into low grade and high grade varienties. The most important factors in the prognosis include histological grading and the ability to achieve a complete surgical resection. We experienced a case of high grade mucoepidermoid carcinoma in pulmonary tuberculosis patient of 67 years old male who has been suffered from left chest pain for several weeks. He was not treated and died seventeen months later.

To Evaluate the clinical characteristics of childhood-onset systemic lupus erythemoatosus (SLE) and analyse the factors related to outcome of renal function in lupus nephritis, we reviewed medical records of 18 cases of SLF diagnosed at the Department of Pediatrics. Pusan National University Hospital from January 1981 to December 1990. The results were as follow: 1)Male to female ratio was 1:2.6. 2) Nephropathy was the most common initial impression, and 8 cases were diagnosed as SLE at first. 3) The clinical menifestation. was ANA (+), malar rash, renal disorder, hematologic disorder in frequency. 4) Diffuse proliferative lupus nephritis was the most common in renal histopathologic studies. 5) Among the follow-up cases, active lupus was 39%, remission was 28%. 6) As factors related to outcome of lupus nephrits were, hypertension and proteinuria were siginificant statistically.

"Capsaicin, the pungent principle of hot peppers, is a neurotoxin that depletes primary sensory neurons of neuropeptides like tachykinin. The objectives of these experiment was to examine the effects of capsaicin on Salmonel/a typhimurium-induced production of cytokines such as TNF-a, IL-1B, IL-6, IL-10 and IL-12 and on production of nitric oxide in peritoneal macrophages. In addition, the effects of capsaicin on survival rates of S. typhimurium-infected mice and on nuclear transcription factor (NF-kB) activation were also investigated. Mice were pretreated with a single s.c. injection of 100 ug of capsaicin and were infected i.v. with S. typhimurium (5xO5/mouse) in 0.2 ml volume after capsaicin pretreatment. The serum cytokine levels were measured 30, 60, 120, 180 and 240 min after Salmonella infection, using ELISA kits. The activation of NF-B was also examined by gel shift assay in spleens, thymuses and brains of mice that had been pretreated with a single s.c. injection of 100 ug of capsaicin. It was found that Sa/mone/la infection induced the production of TNF-a, IL-1B, IL-6, IL-10 and IL-12, but capsaicin pretreatment inhibited the production of TNF-a, IL-1B, IL-10 and IL-12, but enhanced IL-6 production 120 min after Salmonella infection. Interestingly, the capsaicin pretreatment inhibited the activation of NF-kB in spleens and thymuses. There were no differences in the numbers of bacteria in livers, brains, spleens, kidneys and lungs between capsaicin- pretreated mice and the control animals in applied experimental conditions. Suprisingly, however, capsaicin pretreatment increased both the survival rates of Sa/mone//a-infected mice and production of nitric oxide by peritoneal macrophages compared with capsaicin-untreated control mice. Taken together, these results indicate that the capsaicin-sensitive primary sensory neurons may play an important modulatory role in the production of cytokine, nitric oxide and NF-B activation and the pathogenesis of salmonellosis."
