1.A STUDY ON THE PHYSICAL CHARACTERISTICS OF THE THREE COMMONLY USED DIE SPACING MATERIALS.
The Journal of Korean Academy of Prosthodontics 1999;37(5):640-650
As an optimal quality of the restorations, there should be a least amount of seating discrepancy between the casting and abutment teeth. However, high viscosity of the cementing medium and its resulting thickness ay prevent complete seating of the restoration. The use of die spacing material provides adequate internal relief for the cementing medium. The purpose of this study is to compare the thickness of three commonly used die spacing materials. Materials and Methods : Stone plates were fabricated and divided into 12 sections to be painted with die spacers. Tru-Fit, Whip-Mix and Belle de St. Claire die spacer which are commonly used in dental practice were tested in this study. Each die spacers were painted layer by layer according to the manufacturer's recommendation. The average thickness of each die spacers were measured with light microscope(x100) and compared between them. Results and Conclusions: A silver-colored Tru-Fit die spacer has the lowest value of thickness without statistical significance comparing with a gold-colored Tru-Fit die spacer and a gray layer of Whip-Mix die spacer has the highest value of thickness without any statistical significance comparing with Belle de St. Claire die spacer. Three and four layers of Tru-Fit die spacer and two layers of Whip-Mix and Belle de St. Claire die spacers seem to be in the acceptable range of thickness of 25 to 45micrometer for optimal seating of the restorations. The standard experimental design and method should be further evaluated for more consistent and objective results.

Prostaglandins which are produced from amnionic cells are known to play a major role in uterine contraction and cervical dilatation in human. Recently it is reported that aspirin increases the expression of PGHS-1 and PGHS-2 in trophoblast cells from placenta. We examined here the changes of immunoreactive prostaglandin H synthase (PGHS) level by aspirin in cultured cells from amniotic fluid and human amnionic WISH cells. PMA (10-7 M), an activator of protein kinase C increased the induction of PGHS-2 in both cells with or without fetal calf serum. PGHS-2 protein was also increased significantly by 10-4 M aspirin at 6 hours in both cells in the presence of serum but it was not increased in the absence of serum. The expression of PGHS-1 protein was enhanced by asprin but not by PMA in the absence of serum. Other anti-inflammatory drugs such as acetaminophen, indomethacin, dexame- thasone, and mefenamic acid increased the PGHS-2 protein level in WISH cells. PMA-induced PGHS-2 expression in WISH cells was not decreased by aspirin, on the contrary, the level was increased additively. Our results show that the increased expression of PGHS in amnion cells or other amniotic fluid cells by aspirin and other several anti-inflammatory drugs is through an unidentified effect rather than feedback effect by depletion of prostaglandin.

For trauma patients with severe shock, massive fluid resuscitation is necessary. However, shock and a large amount of fluid can cause bowel and retroperitoneal edema, which sometimes leads to abdominal compartment syndrome in patients without abdomino-pelvic injury. If other emergent operations except intraabdomen are needed, a distended abdomen is likely to be recognized late, leading to multiple organ dysfunction. Herein, we report two cases of a 23-year-old woman who was in a car accident and a 53-year old man who was pressed on his leg by a pressing machine; severe brain swelling and popliteal vessel injury were diagnosed, respectively. They were both in severe shock and massive fluid resuscitation was required in the emergency department. Distended abdomen was recognized in both the female and male patients immediately after neurosurgical operation and immediately before orthopaedic operation in the operating room, respectively. Decompressive laparotomy revealed massive ascites with retroperitoneal edema.

Lobular carcinoma of the male breast is very rare, because of the absence of lobules in the normal male breast. Herein, a case of lobular carcinoma of the male breast with cellular features of signet ring cells is described. A 57-year-old man presented with a left breast mass. Histologic examination showed classic invasive lobular carcinoma with in situ component. Most infiltrating tumor cells had a prominent signet ring cell appearance. The patient was phenotypically male and had fathered children. There was no history of predisposing factors to breast lesion, such as hormone use or gynecomastia.
