Congenital M llerian anomalies of uterus are so infrequently encountered and endometriosis, primary infertility, hematometra, and urinary tract anomalies are claimed to be common complaints in women with unicornuate uterus. We report one case of rudimentary horn associated with agenesis of right kidney and pelvic endometriosis which is presented with brief review of literature about anomaly of the female genital tract.

We report an extremely specific case of Pendred's syndrome, originally described with an association of thyroid organification defect and hearing impairment; normal-sized thyroid, severe hypothyroidism manifested by profoundly retarded physical and mental development, cardiomegaly and severe hypochromic & microcytic anemia associated with asymmetrical septal hypertrophy.

Purpose: The threshold levels for symptom development of pollinosis vary among studies and countries. This study aimed to determine currently used threshold levels for it. Methods: Oak, pine, Japanese hop, and ragweed pollen samples were collected daily for 8 years from the Seoul and Guri areas. A total of 792 subjects with allergy to these pollens were recruited. The symptom index (SI) was assessed through telephone interviews and allergy questionnaires, and data were analyzed using decision tree. Results: The risk index for oak pollen allergy was “mild” when the pollen count was 0–2 grains/m3 , “moderate” when it was 3–11 grains/m3 , “severe” when it was 12–28 grains/m3 , and “dangerous” when it was ≥ 29 grains/m3 . The risk level for pine pollen allergy was “mild” when the pollen count was 0–4 grains/m 3 , “moderate” when it was 5–42 grains/m3 , “severe” when it was 43–66 grains/m3 , and “dangerous” when it was ≥ 67 grains/m3 . For Japanese hop pollen allergy, the risk level was “mild” when the pollen count was 0–8 grains/m3 , “moderate” when it was 9–10 grains/m3 , “severe” when it was 11–19 grains/m3 , and “dangerous” when it was ≥ 20 grains/m3 . Finally, for ragweed, the risk level was “mild” when the pollen count was 0–1 grains/m3 , “moderate” when it was 2–6 grains/m3 , “severe” when it was 7–33 grains/m3 , and “dangerous” when it was ≥ 34 grains/m3 . Conclusions Revising the threshold levels for the risk index for pollen allergies may be useful for developing pollen prediction models for patients with pollen allergies in Korea.

The bone graft materials are grossly divided into autogenous bone, allogenic bone, xenogenic bone, and alloplastic material. Among the various allogenic graft materials, hydroxyapatite(Ca10(PO4)6(OH)2, HA), the main inorganic phase of human hard tissue, is widely used as a repair material for bones. When HA applied to bony defect, however, it may be encapsulated with fibrous tissue and floated in the implanted area by the lack of consolidation. Fluoridated hydroxyapatite(Ca10(PO4)6(OH)2, FHA), where F- partially replaces the OH- in the hydroxyapatite, is considered as an alternative material for bone repair due to its solubility and biocompatibility. This study was designed to find out the bone healing capacity of FHA newly produced as a nanoscale fiber in the laboratory. We implanted HA and FHA in the rabbit cranium defect and histologically analysed the specimen. The results were as follows. 1. In the 4 weeks, fibrous connective tissue and little bone formation around materials of the experimental group I implanted HA were observed. In the experimental group II implanted FHA, newly formed bone around materials were observed. 2. In the 8 weeks, the amount of newly formed and matured bone of the experimental group II was more than the experimental group I and control group. From the results obtained, we suggest that FHA, newly synthesized, is relatively favorable bone substitute with bioconpatibility and has better bone healing capacity than pure HA.

The purpose of this study was to compare the marginal fit of provisional restorations by differentiating the removal time and setting temperature during resin polymerization. After mixing autopolymerizing methyl metharcrylate resin, the material was placed in a preformed resin shell crown. The crown was seated on a die with 1mm shoulder margin. Crowns were removed after 3,4,5,6 minutes and polymerization was continued under the following conditions : 25degrees C air,30degrees C, 40degrees C, 50degrees C,60degrees C,70degrees C water. After polymerization, the crown was sectioned. The marginal & occlusal discrepancies were measured. The mean marginal discrelpancies at 3 minutes, 4 minutes, 5 minutes and 6 minutes of removing time were 96.6micrometer,84.6micrometer, 86.7micrometer and 105.6micrometer.The mean occlusal discrepancies at 3 minutes, 4 minutes, 5 minutes and 6 minutes of removing time were 106.7micrometer, 89.3micrometer, 98.6micrometer and 127.7micrometer.There was significant difference between 4 minutes group and 6 minutes group in occlusal discrepancies. The mean marginal & occlusal discrepancies for crowns polymerized in 25degrees C air were 98.2micrometer and 124.1micrometer. The crowns polymerized in 50degrees C water demonstrated the smallest marginal & occlusal discrepancies. The mean value of marginal & occlusal discrepancies in 50degrees C water were 73.1micrometer and 77.5micrometer. These values were smaller than that of 25degrees C air.There were significant differences in the occlusal discrepancies between 25degrees C air and water conditions of 50degrees C water (alpha=0.05) but, no significant differences in marginal discrepancies. There was no significant difference in the interaction between time and temperature. 4 minutes waiting time & 50degrees C water polymerizing condition produces the best fit at the margin of the provisional crown.

About 15 to 20% of ovarian tumors are of germ cell origin, and about 95% of these are cystic teratoma. when the teratoma is composed either entirely or predominantly of thyroid tissue, it called struma ovarii. Struma ovarii represents about 2.7% of cystic teratoma. The incidence of malignant struma ovarii is probably much less than 5% of all struma ovarii. We have observed a case of malignant struma ovarii originated from the left ovary of a 46-year-old woman, and present this case with a brief review of concerned literatures.
