The fact that therapeutic hypothermia (TH) has lowered intracranial pressure and protected brain in severe traumatic brain injury (TBI) is well known throughout past sources and experimental data. In this paper, the result of TH in TBI needs to be confirmed. The result of North American Brain Injury Study; Hypothermia (NAVIS-H) 1 and 2, Eurotherm3235, Japan trauma society study was reviewed throughout randomized controlled study which performed recently. The prognosis was not confirmed throughout TH in NAVIS-H1; however, there was statistical significance among the group of 45 years or less and below 35 degree in celcius which checked when he or she visited initially. Hence, NAVIS-H2 study was preceded. In patient who had surgically removed hematoma, the effects of TH were proved compared to diffuse brain damage in NAVIS-H2 study. This was found in the result of Japan neurotrauma data bank. Eurotherm study has been doing, which leads to collect many data later on. The TBI of TH makes them better prognosis in patients who had surgically removed hematoma and lowered initial body temperature. Later on, it is considered further study is necessary.

Before impression making in the fixed restorations or other prosthesis, hemostatic solutions are used for hemostasis and moisture control. Hemostatic solutions effectively control bleeding but their major ingredients, acid removes smear layers which are formed in the tooth preparation, exposes the dentinal tubular orifices which are occluded by smear layers, makes dentinal tubular fluid displace more easily to the various external stimulus, and according to the hydrodynamic theory, consequently causes dentin hypersensitivity. To know the effect of hemostatic solutions on dentin permeability, coronal dentin discs, 1 mm in thickness, were prepared from extracted third molars free from decay and wear, and a spilt chamber device was used. Hydraulic conductance values and SEMs, which were measured before and after treatment with Astringedentr , Altract and Epri-dent , were compared and analyzed. The following conclusion were drawn : 1. Hydraulic conductance values which wee measured after the treatment of hemostatic solutions were increased in all groups(p<0.05). 2. %change values of hydraulic conductance were compared but no significant difference was found among the three hemostatic solutions(p<0.05). 3. on SEM observations of all groups, after treatment smear layers were removed and dentinal tubular orifices were partially exposed. on the basis of these conclusions, the reckless use of hemostatic solutions should be restricted, and when in use, various methods should be considered to protect dentin.

We evaluated the characteristics of HMB-45 monoclonal antibody(MoAb) and compared it with a polyclonal anti-S-100 antibody in immunohistochemical staining of 22 primary melanomas of the skin ; 13 acral lentiginous melanomas(ALM), 3 superficial spreading melanomas(SSM), 4 lentigo maligna melanomas(LMM), 3 nodular melanomas(NMM). All speimens were formalin-fixed and paraffin-embedded, and were studied with the avidin-biotin-peroxidase complex technique. The results can be summarized as follows : l. In all tissue specimens, all or some of the melanoma cells in the dermis reacted with HMB-45 MoAb and anti-S-100 protein. 2. HMB-45 MoAb is more sensitive in detecting malignant melanoma cell heterogeneity t,han anti-S-100 protein. 3. Melanoma cells within the epidermis in 6 of 12 ALMs and 3 of 4 LMMs did not react with anti-S-100 antibody, whereas most melanoma cells within epidermis of 12 ALMs and 4 LMMs reacted with HMB-45 monoclonal antibody. These results indicated that immunohistochemical staining with HMB-45 MoAb and anti-S-100 protein is very useful in the study of biologic behavior of malignant, melanoma.

Dysregulation of TGF-beta that is a modulator of cell growth and differentiation can result in uncontrolled growth and tumor formation. Monitoring these pattern of genes and protein expression during tumor development will provide a basis for understanding normal growth and distortion of osteochondrogenesis. Our comparative studies on the experssion of TGF-beta protein indicate that TGF-beta may primarily be a regulator of epithelial differentiation during tooth development (between 4 weeks and 40 gestational weeks) and tumorigenesis of odontogenic neoplasm (ameloblastoma). In early human tooth germ (cap/early bell stage) TGF-beta protein was found in the epithelial dentallamina and enamel orgen. TGF-beta experessions were seen in inner and outer dental epithelium during bell stage. During enamel and cementum appositional stage, TGF-beta expression shifted from the ameloblast to the odontoblast. In eruption stage, TGF-beta expressions look like moderate positive pattern in odontoblast and rare pattern in enamel, dentin and cementum. TGF-beta expressions of follicular and plexiform amelobalstoma are moderate positive reaction in ectodermal tumor components and mild positive in vessels of stroma tissue. In acanthomatous type, TGF-beta expression was shown severely positive finding in stellate reticulum cell. TGF-beta expressions were noted moderate reaction in margin of tumor epithelium and stellate reticulum cell of granular ameloblastoma. In unicystic ameloblastoma, TGF-beta expression was rare feature in cystic luminal epithelium. With these result, I should be suggested that TGF-beta may play an important role in epithelial-mesenchymal interactions in human tooth morphogenesis and development of odontogenic epithelial tumors.
