INTRODUCTION There are three factors for successful implantation. These are embryo quality, uterine receptivity, and synchronization between embryonic and endometrial development. Despite remarkable progress in investigating embryos in human IVF, there has been slow progress in exploring the implantation process. It may be due to two reasons as follow. First, it is difficult to directly investigate the mechanism of implantation in the human, because of ethical considerations. Second, there is no sensitive and widely accepted marker for assessing endometrial development. Since the finding of a novel standard for dating endometrial biopsy by Noyes et. al.,. in 1950, there have been many attempts to identify suitable markers for uterine receptivity. Those include ultrasonographic changes (Ueno et.al., 1991; Grunfeld et al.,1991), three dimensional morphological changes of the endometrium such as pinopode formation (Market or alphaf., 1987; Mantel or alphaf., 1991; Nikas et al., 1995; Psychoyos & Nikas, 1994), integrin expression (Ilesanmi et al., 1993; Lessey et.al., 1992; Lessey, 1994), and measurement of endometrial proteins (Hell, 1986;Fay & Crudzinskas, 1991). Investigations in the rat (cartel et al., 1991)and human (cartel et al., 1987; Nikas et al., 1995; Psychoyos & Nikas, 1994) suggested the presence of pinopodes as a marker for the receptive phase.4 chronological barrier in uterine receptivity could be one of the major factors limiting IVF pregnancy rates. If we were able to manage the 'implantation window' we may be able to improve implantation and pregnancy rates in the human IVF program. In 1987, Martel et al., found early appearance of pinopodes in stimulated cycles for IVF compared to natural cycles in humans (Marcel et al., 1987). This effect was found in patients stimulated with clomephene citrate/hMG/hCG. The purpose of the present study was to evaluate the endometrial development in IVF patients stimulated with either by FSH/hMG/hCG or with GnRH agonist down regulation.

PURPOSE: The purpose of this study was to determine gender differences in effects of self-efficacy, exercise benefits and barriers, and demographic factors on the physical activity. METHODS: Seventy sedentary office workers, 35 male and 35 female, from a major airline company, completed a questionnaire from March 28 to April 5, 2012. Steps and body mass indices were measured using a CW-700/701 (Yamax) pedometer and Inbody 720 (Biospace), respectively. Data were analyzed using t-test, chi2-test, multiple linear regression, and simultaneous quantile regression. RESULTS: For male workers, exercise self-efficacy had a significant effect on physical activity, but only when respondents were at 10%(3,431 steps/day, p=.018) and 25%(4,652 steps/day, p=.044) of the physical activity distribution. For female workers, marital status was significantly related to physical activity, but only when respondents were at 10% (3,537 steps/day, p=.013) and 25%(3,862 steps/day, p=.014) of the physical activity distribution. CONCLUSION: Quantile regression highlights the heterogeneous effect of physical activity determinants among office workers. Therefore intervention strategies for increasing physical activity should be tailed to genders as well as physical activity levels.

The determination of the degree and ability of recovery of obstructive hydronephrosis is important in treatment and prediction of prognosis. Among the various methods in determination of the status of kidney, intravenous pyelography is the most important tool to evaluate the morphological and functional changes of kidney in vivo. The purpose of this experiment was the determination of process and recoverability of hydronephrosis depend on duration of unilateral uretreal obstruction. For the experiment, 32 rats were divided into 2 groups; the first group of 12 rats were used to determine the process of hydronephrosis during 1 to 4 weeks of unilateralureteral ligation and the second group of 20 rats were used to determine the recoverability of hydronephrotic kidney depend on same duration of ureteral ligation following relief of ligation. Intravenous pyelography as undertaken and renal angiography, gross and microscopic examination were added. The results obtained are summarized as follows; 1. Kidney enlargement and pelvic dilatation were progressively increased with a relation to duration of ureteral obstruction until 4 weeks. 2. Renal excretory function is not impaired until 3 weeks obstruction, but rapidly impaired to nonfunctioning in 4 weeks obstruction. 3. Renal recovery was possible following relief of ureteral ligation within 3 weeks of ureteral obstruction, but histopathological and functional recovery were impossible in 4 weeks of ureteral ligation. 4. There is no direct correlation between duration of obstruction and recoverability following relief within 3 weeks of uretral obstruction. 5. Intravenous pyelographyis a simple and accurate method to determine the degree of obstructive hydronephrosis and to evaluate morphological and functional recovery of kidney following relief of obstruction.

Benign symmetric lipomatosis is characterised by diffuse symmetric deposits of adipose tissue, predominantly on the neck, shoulder, back and upper extremities. We report a case of benign symmetric lipomatosis in a 61-year-old-man, which was first noted one year previously. It began growing rapidly about 3 months ago and was associated with alcoholic liver disease. Histopathological findings showed that the reticular dermis had been replaced by normal uncapsulated mature fat cells that were slightly increased in number in the fibrous connective tissue. He was treated with theophylline 300mg/day for two months.

Perifolliculitis capitis abscedens et suffodiens is a rare chronic recalcitrant follicular disorder which clinically presents itself as pulstules, nodules, intercommunicating abscess and sinuses that leave atrophic, hypertrophic or keloidal scars. Although the etiology of this of condition is unknown, its association with acne conglobata and hidradenitis suppurativa, collectively termed the follicular occlusion triad, suggest a cammon basic pathogenic mechanism of follicular retention. The therapeutic problem is reflected in the variety of therapies that have been tried with varying degrees of success. We report a case of a 34-year-old man who showed a patch of alopecia on the vertex of his scalp. Clinically, the scalp showed multiple soft fluctuant elevated nodules with nonscarring alopecic patches. We performed a treatment with isotretinoin(13-cis-retinoic acid) during 6 months. The patients clinical appearance was much improved and local recurrence and hair loss have not been observed to date.

We reviewed the computed tomography (CT) of 32 patients with upper lobe collapse to assess the significance of small atypically redistributed pleural effusion (ARPE) in distinguishing the bronchogenic carcinoma (BC) form tuberculosis (TB). Upper lobe collapse was caused by BC in 21 and by TB in 11 of the 32 patients. Small ARPE was Present in 14 of 21 patients with BC and two of the 11 patients with TB, Among 16 patients with small ARPE, CT showd mediastinal invasion in 11 (69%) patients and mediastinal lymphadenopathyn 6 (38%). Our results suggest that small ARPE associated with upper lobe collapse can be used a an auxiliary sign in the differential diagnosis between BC and TB.

BACKGROUND: Korea is, known to be an endemic area of viral hepatitis B, and 5-6% of population are carriers. Immunization can reduce the spread of hepatitis B infection. Hower, not all people respond to hepatitis B immunsation. 5-15% of primary vaccinees fail to be immunized. After revaccination, only 37.5 44% of the primary failures elicit antibody response. Recent studies have reported that it is effective to inject a double dose vaccination in immunocompromsed patients. In some country, they recommend that neonate whode mother is HBV carrier shoud receive double dose vaccination. This study documented the results of double dose vaccintion only once to nonrsponders toward the HBV immunzation. METHODS: Healthy nonresponders to Hepatitis B immunization were recuited from Sep. 1995 to Aug. 1996. Subjects with their AST/ALT level over 40, or over 65 years old were excluded. They were received 2ml of plasma-derived vaccine(Hepavax-B) intramuscularly in the deltoid muscle. Anti-HBs antibody testing were performed at 1 to 3 months after vaccintion. RESULTS: 17 healthy nanreponders to Hepatitis B immunization(male 10, female 7) were included. Their mean ages were 47(32 to64), AST/ALT level 20/19(16 to 28/11 to 35), smoking 4.3pys(1 to 7). Seroconversion occured in 13 of them(76.5%). CONCLUSIONS: Nonresponders to Hepatitis B vaccintion respond well to double dose vaccination once.
