In this study seminal fluid samples were obtained from 20 normal adult males to know the percentage of the spermatozoa containing the fluorescent body (F-body), after staining the seminal fluid with 0.5% aqueous quinacrine HCI. In this study the preparations were observed with an AO fluorescent microscope. The following results were obtained. 1) In 20 men, the mean percentage of F-body containing spermatozoa was 31.3%. 2) There was no relationship between sperm density in semen analysis and F-body rate 3) There was no relationship between sperm motility in semen analysis and F-body rate. 4) In 5 men, methyl alcohol-acetic acid (3:1) preparations, as a fixation solution, showed better F-body rate than that of ethyl alcohol preparations. 5) In 4 men, the preparations which were fixed and stained within 2 hours after obtaining seminal fluid showed better F-body rate than that fixed and stained after 6 hours. 6) In 10 men, after low speed centrifuging of the seminal fluid, the deposit preparations, showed decreased mean percentage of F-body containing spermatozoa by 4.2%.

Pelvic lipomatosis is a very rare condition in which a proliferative process involving the mature fat of the pelvic retroperitoneal space. An X-ray in such cases is characteristic and shows radiolucency of the soft pelvic tissue and bladder is displaced upward and has a gourd-like or inverted tear-drop appearance. In Korea, there is no previous report. Herein we report a case of pelvic lipomatosis and the literatures are reviewed.

BACKGROUND AND OBJECTIVES: Acute coronary syndrome occurs most commonly in the setting of atherosclerotic coronary artery disease, but there is little information concerning the mechanism responsible for the transition from stable to unstable coronary atherosclerotic plaque. Hypothetically, several microorganism(Chlamydia pneumonia, Cytomegalovirus and Helicobacter pylori) and their inflammatory reaction have been suggested as a causative motive in progression of acute coronary syndrome. Although it is unclear whether the serum level of CRP as a inflammatory parameter is concerned with previous inflammatory change or myocardial necrosis, CRP apper to be predictive of higher risk for cardiac event in the patients with acute coronary syndrome. Our objective was to evaluate whether the inflammatory parameters(CRP, ESR and WBC count) is useful in predicting the short-term cardiac risk within 30 days. MATERIALS AND METHOD: One hundred and ten patients with acute coronary syndrome were enrolled from April 1998 through August 1998. Blood samples were collected at 1st hour, 24th hour, 48th hour and 7th day and tested for CRP, ESR, WBC count and CK-MB level. Values of 323 normal were used as control. All patients were followed up for 30 days and assessed for the presence of cardiac complications. RESULTS: Peak CRP value of the patients with acute myocardial infarction(3.4+/-3.85 mg/dL, n=2) was higher than that of the patients with unstable angina(0.7+/-0.93 mg/dL, n=8, p<0.05) and controls(0.3+/-0.48 mg/dL, n=23, p<0.05). Peak CRP value of patients with cardiac complication was higher than that of patients without complication(7.7+/-4.77 mg/dL, n=5 vs 1.3+/-1.74 mg/dL, n=5 ; p<0.05). In multivariate analysis, peak CRP value was the only predictive parameter for development of cardiac complications in the patients with acute coronary syndrome(Odds ratio 4.893, 95% confidence interval 1.212-19.756, p value=.026). In the high-CRP group(>2 mg/dL, n=0), the cardiac complication rate was higher than the low-CRP group(< or =2 mg/dL, n=0) (43.3% vs 2.5%, p<0.05). Peak CRP value was correlated with age(r=.191, p=.045), pulse rate(r=.186, p=.008), left ventricular ejection fraction(r=0.384, p<0.001), peak ESR(r=.383, p<0.001) and peak WBC count(r=.307, p=.001), but not with peak CK-MB level. CONCLUSION: Elevated CRP level in patients with acute coronary syndrome seems to be a valuable prognostic factor for the development of cardiac complications within 1 month after admission.

BACKGROUND: Assessment of segmental wall motion is one of the most challenging tasks in echocardiography. The diagnosis of ischemic heart disease by echocardiography depends on the accurate detection of segmental wall motion abnormalities. However, echocardiographic regional wall motion analysis is impaired by incomplete endocardial definition due to obesity, chronic obstructive lung disease, etc. The purpose of this study was to examine the value of tissue harmonic imaging for endocardial border definition. METHODS: We recorded echocardiograms in 30 consecutive patients, in which more than one segment of left ventricule were poorly visualized, by ATL HDI 3000 and analyzed left ventricular segmental wall motion and then recorded echocardiograms again by tissue harmonic imaging (THI) technique. Endocardial border definition for each segment was graded from grade A to C (grade A in which endocardium is clearly visualized, grade B in which endocardium is poorly visualized and grade C in which endocardium is not seen). Densitometric analysis was perfromed in 10 randomly selected patients. Mean density and dynamic range in histogram were obtained at septum, posterior wall and left ventricle cavity on parasternal long axis view with both techniques. RESULTS: Among total 480 segments, 237 segments (49.4%) were categorized as grade A, 152 segments (31.7%) were categorized as grade B and 91 segments (18.9%) were categorized as grade C in fundamental modes. However, 380 segments (79.2%) were categorized as grade A, 75 segments (15.6%) were categorized as grade B and 25 segments (5.2%) were categorized as grade C in tissue harmonic modes. Visualization of 37.7% (181 segments/480 segments) of all segments was improved in tissue harmonic imaging, with 5.2% (25 segments/480 segments) improved from "not seen" to "clearly visualized". Of these improved 181 segments in THI, 105 segments (58%) were the lateral and anterior walls on apical views. In densitometric analysis of septum, wall density and delta density (wall densityLV cavity density) were significantly higher in THI than fundamental modes (p<0.05). But, W/C ratio (wall density/LV cavity density) was not different between two imaging modalities. In densitometric analysis of posterior wall, all parameters were not significantly different between two imaging modalities. Also, W/C ratio of dynamic range (posterior wall dynamic range/LV cavity dynamic range) was not significantly different between two imaging modalities. CONCLUSION: Tissue harmonic imaging has significant value in endocardial border definition in the patients with poor echocardiographic windows and appears promising with the added advantage of no requirement for intravenous access.

Apocrine adenocarcinoma is rarely reported in the world and only 4 cases are reported in Korean literature. We encountered a case of apocrine adenocarcinoma associated with basal cell carcinoma in a 76-year-old female. Excisional biopsy showed well demarcated basophilic cell mass in the upper dermis and glandular structure in the lower dermis. Basophilic cell mass consisted with basaloid cells and had peripheral palisading arrangement. Glandular structures characterized by cells with abundant eosinophilic cytoplasm showed decapitation secretion. The cells showed nuclear atypicality, plemorphism and prominent nucleoli. The cytoplasm contained PAS-positive, diastase-resistant granules and stains for lysozyme and GCDFP-15(Gross Cystic Disease Fluid Protein-15) were positive.

Langerhans cell histiocytosis is a proliferative disease in which Langerhans cells accumulate in various body sites and cause damage to the affected organs. We report a 7-month-old infant who had only cutaneous lesions and healed spontaneously without treatment. There were rice grain to corn sized erythematous papules and crusted lesions in the chest, abdomen, and back for 2 months. The histologic finding of the lesion showed that the dyscohesive infiltrate, predominantly of histiocytes, were present and extravasated erythrocytes and eosinophils were also found in edematous papillary dermis. Careful examination showed histiocytes with coffee bean or kidney-shaped nucleus which was positive for S-100 protein. The infant had no systemic involvement, and healed spontaneously after 1 month without relapse.
