Mullerian Mucinous papillary Cyatadenernas of Borderline tumor(MMBT) is lined by mucinous epithelium of endocervical type and is characterized by papillae architecturally similer to those of serous horderline tumors, It has been described rarely in the literature, Thia case was reported with a brief review of the concerened literatures. It has important clinical and pathological diBerences from mucinous birderline tumors with intestinal differentiation, but has many similatities to mixed epithelial borderline tumora of Mulierian type. Recently, a case of MMBT in a 22 years old woman was experienced at our department. We presented this case with a brief review of literature.

Orthodontic tooth movement in response to orthodontic force results from actions of osteoclasts and osteoblasts in the cell level. Convincing evidence has now been provided to support the view that osteoclasts are derived from mononuclear cells that originate in the bone marrow or other hematopoietic organs and they migrate to the bones via vascular routes. Nitric oxide(NO), which accounts for the biological properties of endothelium-derived relaxmg factor(EDRF), is the endogenous stimulator of soluble guanylate cylase. The discovery of the formation of nitric oxide(NO) from L-arginine in mammalian tissues and its biologioal roles has, in the last 7 years, thrown new light onto many areas of research. Data from experiments in vitro showed that N-metyl-L-arginine(L-NMA) and L-nitro-L-arginine(L-NAME) are competitive inhibitors of nitric oxide synthase. This study suggest that the multinucleated cells in our culture have characteristics of osteoclasts and that the potential bone cell activity of nitric oxide in vitro may be mediated in part by stimulation of marrow mononuclear cells to form osteoclast-like cells. Bone marrow cells were obtained from tibia of 19-days old chick embryo. After sacrifice, tibia was quickly dissected and the bone were then split to expose the medullary bone. The cells were attached for 4 hours and the nonadherent cells were collected. Marrow cells were cultured in 96-well plate in medium 199. To examine the number of TRAP-positive multinucleated cells(MNCs), 10(-8) M Vit-D3 and various concentration of L-NMA and L-NAME were added at the beginning of cultures and with each medium change. After 7 days of culture, tartrate-resistant acid phosphatase(TRAP) staining was performed for microscopic evaluation. Cells having more than three nuclei per cell were counted as MNCs. The observed results were as follows; 1. 1,25-dihydroxyvitamine D3 stimulated the osteoclast-like multinucleated cells in cultures of chick embryo bone marrow. 2. Nitric oxide synthase inhibitors(NOSI ; N-NMA, N-NAME) stimulated the osteoclast-like cells in cultures of chick embry bone marrow. 3. 1,25-dihydroxyvltamine D3 and nitric oxide synthase inhibitors did not appear to have additive effect on the generation of TRAP-positive MNCs. These results suggest that nitric oxide synthase inhibitors may stimulate the osteoclast-like multinucleated cell formation and fusion in cultures of chick bone marrow.

In order to investigate the level of lead exposure of workers in litharge making industry and to evaluate how lead exposure, personal habit such as smoking and drinking affect the prevalence of lead related symptoms and other study variables, we investigate 114 workers(24 office workers and 90 lead exposed workers) in a litharge making industry. Study variables chosen were blood lead(PbB), zinc protoporphyrin in whole blood(ZPP), Hemoglobin(Hb), hematocrit (Hct), SGOT and SGPT. symptom questionnaires which had 15 lead exposure related symptoms were provided to all workers and filled up by themselves and reconfirmed by physician. The results obtained were as follows; 1. The mean value of PbB, ZPP and SGOT in lead exposed group were higher than those of non-exposed group, and there were no differences of means in other study variables. 2. The smoking and drinking rate of study subjects were 65.8% and 71.0% as a whole. Smoking rates were lower in non-exposed group than exposed group, but drinking rate were not. 3. There were no differences of mean values of study variables between smoker and non-smoker in non-exposed and exposed group, but there was a difference of mean value of SGOT between drinker and non-drinker in lead exposed group. 4. while the symptom prevalence of lead exposed group were higher in neuromuscular category than non-exposed group, those of non-exposed group were higher or same with exposed group in gastrointestinal and general symptom category. 5. The symptom prevalence of smoker were higher than non-smoker regardless of exposure. 6. The symptom prevalence of drinker were only higher in gastrointestinal symptom category than non-drinker. 7. In multiple stepwise regression analysis of lead related symptoms as dependent variable and blood lead, smoking habit, drinking habit and work duration as independent variables, drinking habit contributed to the gastrointestinal symptom category, whereas blood lead and smoking contributed to the neuromuscular symptom category. For the total symptoms work duration and smoking habit contributed significantly.

Atypical polypoid adenomyoma(APA) is a rare benign polypoid tumor arising in the uterine endometrium which was first designated by Mazur in 1981. Microscopic examination reveals architecturally and cytologically atypical endometrial glands separated by intersecting fascicles of smooth muscle cells. The tumor can be misdiagnosed as endometrial adenocarcinoma with myometrial invasion, especially on microscopic examination of a curettage specimen. However a granulation tissue-like stromal response is absent and the smooth muscle in APA is more cellular than that of normal myometrium. We are reporting 2 cases of APA of the uterine endometrium which are 1.5 cm and 1.7 cm in size, respectively, in a 30 and a 22 year-old women. This is the first report in Korean literature using the immunohistochemical staining for smooth muscle actin and desmin.
