Cyclooxygenase (COX) is an enzyme involved in the conversion of arachidonic acid to prostaglandins(PGs), and exists in two forms, COX-1 and COX-2. COX has been reported to be involved in early implantation by secretion of PGs which causes permeability of vessels and reaction of decidual cells around the implantation site. Recently, in mice and sheep studies, COX-1 and COX-2 expression in the endometrium has been reported to be different according to implantation and stages of the estrous cycle, but expression of COX-1 and COX-2 in human endometrium during the menstrual cycle has not yet been established. The purpose of this stuffy was to observe the variances of COX-1 and COX-2 expression by immunohistoehemical staining in endometrial samples obtained from human hysterectomy specimens and biopsies of women of reproductive age according to different stages of the menstrual cycle. Also, we attempted to observe COX-1 and COX-2 expression in the epithelial and stromal cells of the endometrium obtained during the mid-secretory phase, which were cultured separately. COX-2 showed a cyclic pattern of expression according to the different stages of the menstrual cycle and was strongly expressed particularly at the mid-secretory phase which corresponds to the time of implantation. However, COX-1 tended to be increased in the early proliferative, and mid- and late secretory phases, but was also expressed in the whole menstrual cycle showing no particular pattern. In the separately cultured cells COX-1 was expressed in epithilial cells and COX-2 in the stromal cells. The above results suggest that since COX-2 is expressed at the same time as implantation and cultured cells display a specific secretory pattern, COX-2 has inductive endocrine enzyme properties and has an important effect on endometrial cells during implantation. Also, COX-2 expression in endometrial cells may be utilized as a useful marker of endometrial maturation.

We repoarted a rare case of AML atypical M2 who developed granulocytic granulocyte sarcoma in the meninges which was induced complete remission with all-trans retinoic acid (ATRA), daunorubicin and cytosine arabinoside (Ara-C). Morphological and immunophenotypic study of leukemic cells in this patient suggested acute promyelocytic leukemia. However, leukemic clees lacked both t (15;17) and PML-RARalpha gene rearragement, rather showed t (8;21). The patient was diagnosed as AML atypical M2.

BACKGROUND: To investigate the usage patterns of sedatives, analgesics and neuromuscular blocking agents (NMBAs) in patients requiring mechanical ventilation more than 72 hours in intensive care units (ICUs) of Korea. METHODS: A total of 536 patients continuing mechanical ventilation more than 72 hours had been enrolled among the twenty-one ICUs of Korea from May 2003 to July 2003. Data about mechanical ventilation, the use of sedatives, analgesics, and NMBAs were prospectively collected for four weeks. We analyzed the patterns of using these drugs and effects on outcomes. RESULTS: More than half of the patients (50.4%) received sedative drug alone. Most commonly used sedatives and analgesics were midazolam and morphine. NMBAs were administered in 41% of the patients. Volume controlled ventilation mode was associated with more frequent use of NMBAs. There were no significant differences in outcome variables among the usage patterns of sedatives, analgesics and NMBAs. CONCLUSIONS: Our investigation shows that analgesics were much less frequently used in the intensive care units of Korea compared with the use of sedatives. And the use of NMBAs were quite a common.

This study investigated the recovery and absorption rates of murine norovirus, a surrogate for human norovirus, by using NanoCeram(R) filters which served as a tool for recovering viruses. In the study, two types of NanoCeram(R) filters were employed: one was a cartridge type and the other was a disc type (phi 47 mm) whose surface area is 75 times smaller than the cartridge type. The analytical method was the real-time reverse transcription-polymerase chain reaction (RT-PCR). The study found that the average recovery rates of the cartridge type and the disc type were 30.9% and 29.5% respectively. Since these two rates were very close to each other, the adsorption rate of the cartridge type could be predicted with the disc type. Analyzing recovery and absorption rates of the disc type based on different filtered volumes showed that when the volume increased from 0.5 L to 20 L, the average recovery rate rose from 14.78% to 30.41 %, while the average absorption rate dropped from 56.33% to 10.48%. The increase in turbidity from less than 1 NTU to less than 3 NTU raised the average recovery rate from 47.23% to 82.84%.

BACKGROUND: Subclinical hypothyroidism is frequently discovered from hypercholesterolemic adults. It is defined as an asymptomatic state which characterized by normal free thyroxine (FT4) and elevated thyroid stimulating hormone (TSH) level. Hypercholesterolemia is a major risk factor for coronary heart disease, however hypercholesterolemia caused by hypothyroidism can be easily managed by thyroid hormone replacement. The screening of thyroid disease in hypercholesterolemia patient must be emphasized in order to find out correctable hypothyroidism. So we screened the prevalence of overt and subclinical hypothyroidism at different hypercholesterol levels in middle-aged men and women and also analyzed the correlation between TSH and total cholesterol level. METHODS: We measured serum TSH levels and FT4 by radioimmunoassay from 491 patients with hypercholesterolemia. The subjects were divided into two groups according to serum cholesterol level. Group I was serum cholesterol > or = 240 -<300 mg/dL and group II was > or = 300 mg/dL. Subclinical hypothyroidism was defined as TSH levels higher than 4 mU/L, in the presence of normal FT4 concentration. RESULTS: The overall prevalence of subclinical and overt hypothyroidism was 3.4% and 2.5% in men and 4.7% and 3.5% in women of middle age. In men the prevalence of overt and subclinical hypothyroidism increased from 2.3% of group I to 16.1% in the group II (p<0.05). In women that increased from 5.2 % to 12.9 % (p<0.05). After age correction, an increase of 1 mU/L TSH in men was associated with an increase of 3.2 mg/dL total cholesterol (p<0.01). A similar trend was also found in women (2.1 mg/dL p=0.052). CONCLUSION: In this population, the prevalence of hypothyroidism is up to 16.1% in middle-aged men, 12.9% in middle-aged women with high total cholesterol and it may justify screening of thyroid disease in hypercholesterolemic patients especially in clinical practice.
