To demonstrate possible influences of general bone density on the mandible, histomorphometric analysis was carried out in mandibles and iliac bones and the correlation of the two bone densities was tested. Comparison of bony density in women and men over 60 years in the mandible was carried out too. Quantitative computed tomography (GCT) was taken in cross-section of mandibles at the same site where histomorphometric analysis was performed to evaluate the reliability of QCT. The analysis included 40 cadavers with no known disease affecting the bones. The subjects consisted of 15 females and 25 males with a mean age of 60.3 years. Spearman correlation analysis and Wilcoxon rank sum test was performed. The results were as follows. 1. There was statistically no correlation between the mandible and iliac bone in the walues of corrected cortical width (CCW), cortical porosity (POR) in cortex, and total bone volume(TBV), mean trabecular plate thickness (MTPT), mean trabecular plate density (MTPD), and mean trabecular plate separation (MTPS) in trabecular bone. 2. Comparison of women and men over 60 years, men had statistically higher bone density than women except for POR of buccal and lingual cortex, and MTPD of alveolar trabeculae in mandible. 3. There was statistically significant correlation between TBV of trabecular bone and CT NO., but not between POR and CT No. In mandible. According to the results above, there was no correlation between mandible and iliac bone density and between mandibular bony density and age. Further studies are required to support the results. A more noninvasive method to be able to measure the bone density of mandible should be developed and it is necessary to accumulate data on the normal values of bone density of mandible according to age and sex. Further study should be carried out about QCT to measure mandibular bony density using QCT.

The fibrofolliculoma is characterized by abnormal hair follicles with epithelial strands extending out from the infundibulum of the hair follicle into a hyperplastic mantle of specialized fibrous tissue. We have seen a peculiar case of a 1 year and 2 months old male who had a solitary papule on the left side of his face which histologically showed a typical fibrofolliculoma pattern.

This dental anthropological study was performed to analyse male and female students of Che-ju high school students. Cephalometric X-rays and dental casts were obtained of 60 male and 60 female students and the Mean and Standard Deviation were obtained. There was no difference in craniofacial morphology between male and female students but the size of craniofacial skeleton of the male is bigger than that of the female. The distance from NB line to pogonion is longer in the male group, and it meant that mandibular symphysis of the male is well developed than the female. The size of teeth of the male is larger than that of the female and is significant in upper and lower canine and first molar. The size of upper arch width, intercanine width, basal arch width and lower basal arch width of the male is larger than that of the female, but arch length of the male and the female showed no significant difference.

We performed anthralin comparative study(0.01% vs 0.1%) to assess the effectiveness of low-strengh anthralin therapy in 34 psoriatic patients and the resu1ts can be summarized as follows. 1. In the case of 13 patients using Burdick UVB larnp, in 1 patient the effect of 0.1% anthralin was superior to that of 0.01% anthralin from the start to the end of treatment, in 5 patients(38.5%) initially the effect of 0.1% anthralin was superior but in time became equal to that of 0.01% anthralin, and in 7 patients (53.8%) the effect of either side was same throughout the courae of the treatment. In the case of 21 patients using Waldmann UVB cabinet, there were 2(9.5 %), 3(14.3%) and 16 patients(76.2%) in the order named above. 2. The side effect of 0.1% anthralin was more severe than or at least the same as that of 0.01% anthralin in every patient who complained about side effects. So low-strengh anthalin-UVB phototherapy was thought to be the effective and alternative method of treatment particularly for the purpose of lessening the side effects.

STUDY DESIGN: This study was undertaken to document the effect of TGF-beta 1 and TGF-beta2 on the proliferation of lumbar facet joint capsule. OBJECTIVES: To study the effect of TGF-beta1 and TGF-beta2 on the proliferation of lumbar facet joint capsule and their proliferation mechanism. SUMMARY OF LITERATURE REVIEW: TGF-beta1 and TGF-beta proliferated mesenchymal tissue . This proliferatine mechanism was involved of PLC-gamma- 1 and tyrosine kinase in signalling. MATERIAL AND METHODS: Three lumbar facet joint capsule was cultured in DMEM-20 media. Its proliferatine and inhibited effect was studied under the metabolic inhibitors and trasnsforming growth factors . RESULTS: TGF-beta1, and TGF-beta2, increased cell proliferation dependent on time and dosage. Both of TGF-beta1, and TGF-beta 2, specific antisense oligonucleotide blocked tile autoc.me effect of growth factor, PLC-gamma-1 specific antisense oligonucleotide inhibited the effect of TGF-beta 1, and TGF-beta2, Genistin inhibited the effect of TGF-beta 1, and TGF-beta2, in time and dosage dependent manner. CONCLUSION: The cell proliferation of lumbar facet joint capsule was involved in PLC- gamma-1 and tyrosine kinase in signalling.

We experienced a case of purpura pigmentosa chronica in a 9-year-old girl whose skin lesions are widespread, so that face is also involved in addition to the lower extremi ties, trunk, and upper extremities.

Colonization of mammary cancers by melanocytes with heavy pigmentation of cancer cells by melanin can occur very rarely. It is not certain which mechanism operates to achieve this transfer. However, the melanocytes might inject melanin through their dendritic processes or alternatively, the cancer cells phagocytose the terminal parts of the dendritic processes with subsequent dispersal of the contained melanin contained melanin granules. We report a case of infiltrating ductal carcinoma of breast with melanocyte colonization and pigmentation in a 59-year old female.
