The histochemical study, especially the demonstration of alkaline phosphatase and acid phosphatase was carried out in order to differentiate ascarides of human and pigs. The experimental material were obtained from naturally contaminated men and pigs. As the histochemical staining methods the Gomori's was applied for acid phosphatase and Takeuchi and Takami's for alkaline phosphatase. The results obtained were summerized as follows : In the pig's ascarides, alkaline phosphatase was richly found in the subcuticular tissue, lateral line, median line, strial zone and epithelial cells of the intestine, epithelial cell and basal membrane of the ovary, the same part of the uterus and also in eggs. Acid phosphatase in the pig's ascarides were distributed in the same part as alkaline phosphatase. It, however, was darker brown in the soft tissue of the lateral line, epithelium of excretory canal, median bundle, whole zone of the intestine and intestinal contents. In the human ascarides, the alkaline phosphatase was distributed in the testes and the parts where the acid phosphatase was found in the pig ascarides. The acid phosphatase in the human ascarides was demonstrated in the subcuticular tissue, soft tissue of lateral line, epithelium of excretory cells, strial zone, transparent zone, granular zone and epithelial zone of esophagus and intestine, ovary, ova in the uterus, epithelial cell and basal membrane of the uterus and in testes. In the pig's ascarides, the area of distribution of alkaline phosphatase was restricted, but that of acid phosphatase was wider. In human ascarides, the area of distribution of alkaline phosphatase and acid phosphatase was not significantly different, but in some part showed slight difference. Above mentioned finding suggest that the distribution of phosphatase could be utilized for the differentiation of ascarides of human and pig.

The effect of amiodarone on reperfusion arrhthmias after release of left anterior descending coronary artery(LAD) occlusion was studied in 22 anesthetized cats. All cats underwent 20 minutes LAD occlusion followed by reperfusion and amiodarone(20mg/Kg) or normal saline was given on cats which had reperfusion arrhythmias through the left ventricular catheter to observe the antiarrhythmic effect of amiodarone. And also the incidence and type of arrhymias during occlusion and reperfusion were analyzed. During the 20 minute LAD occlusion, 10 of 22 cats(45%) had no arrhythmias, and 12 cats(55%) had nonsustatined ventricular tachycardia. After release of occlusion, 5 of 22 cats(23%) had no arrthmias, and 17 cats(77%) developed sustained ventricular arrhythmias(ventricular tachycardia (n=5), ventricular fibrillation(n=12)). The 17 cats which had reperfusion arrhythmias were randomly divided and given normal saline(control(n=8)) or amiodarone(amiodarone group(n=9)). There was no difference on 2 groups. The reperfusion arrhythmias disappeared in 6 out of 9 cats(66.7%) vs none of 8 controls(P<0.01). We conclude that amiodarone seems to be the effective antiarrhythmic drug on reperfusion arrhythmias after release of LAD occlusion in anesthetized cats, and might be useful for the treatment of reperfusion arrhythmias in human.

OBJECTIVE: To elucidate the correlation of nitric oxide (NO) concentrations in follicular fluid (FF) with the ovarian response as well as the age in women undergoing controlled ovarian hyperstimulation (COH). METHODS: This study was performed in 72 cycles of whom underwent COH for in vitro fertilization at infertility clinic of Changwon Hanmaeum Hospital and Pusan National University Hospital from Aug., 2003 to Dec., 2003. Each FF was collected at the oocyte retrieval and NO concentrations in FF were assessed. We analyzed the correlation of NO concentrations in FF with the ovarian response as well as the age in women undergoing COH. RESULTS: Among 72 cycles, the clinical pregnancy rate was 37.5% (27cycles). There were no significant differences in patient's age, ampules of gonadotropins used, estradiol level on the day of hCG administration, the number of oocytes retrieved, and fertilization rate between pregnant and nonpregnant groups. However, negative correlation was found between the follicular size and NO concentrations in FF. No significant correlation was found between age and NO concentrations in FF. Comparing NO concentrations in FF between pregnant and nonpregnant women by age, NO concentrations in FF were higher at nonpregnant women, significantly those of them more than 40 years old. CONCLUSION: These results suggest that NO concentrations in FF cannot be a marker for the ovarian response, and have no correlation with all parameters of COH including patients' age with exception for the follicular size.

OBJECTIVE: To establish the evaluation system of the quality of oocytes on the basis of the incidence of cumulus cells apoptosis, to investigate the relationships between the incidence of cumulus cells and the outcomes of IVF-ET. METHOD: Thirth-four cycles undergoing controlled ovarian hypersimulation for IVF-ET with tubal infertility (23 cycles) or unexplained infertility (11 cycles) were included in this study. Cumulus cell masses surrounding mature oocyte and co-culture of embryos with autologous cumulus cells during IVF-ET process. The incidence of apoptosis in cumulus cells was assessed by apoptosis detection kit fluorescein. The effect of co-culture using cumulus cells and the incidence of cumulus cells apoptosis. RESULTS: The results were as follows: 1. The incidence of apoptosis in cumulus cells markedly increased in patients aged 40 or over, while the fertilization rate was greatly decreased in those age group. 2. Apoptosis in cumulus cells was found in both the fertilized oocytes and unfertilized oocytes, but the incidence of apoptosis was higher in unfertilized oocytes. 3. There is no clear correlation between apoptosis in cumulus cells and the number of oocytes retrieved. However, the incidence of apoptosis was increased when the number of oocytes retrieved was 5 and fewer in comparison with 6~10. 4. Embryo grade was significantly affected by the incidence of apoptosis in cumulus cells. 5. Pregnancy rate of IVF-ET per cycle was 29.4%, and the pregnant group had the higher fertilization rate and a significantly lower incidence of apoptosis in cumulus cells compared with the nonpregnant group. 6. When cumulus cells were used as helper cells in the co-culture of the embryo, in vitro activity of cumulus cells based on morphological change and proliferation did not influence the quality of embryo, but was closely associated with the implantation rate and pregnancy rate, which was enhanced when morphological changes and proliferation of cumulus cells was more active. 7. This difference in the outcome of IVF-ET according to in vitro activity of cumulus cells used for co-cultue was not associated with the incidence of apoptosis in cumulus cells, but rather had likely relations with the different secretion pattern of protein, which may be an embryotrophic factor by cumulus cells. CONCLUSION: These results suggest that the incidence of apoptosis in cumulus cells can be used in predicting oocyte qualities and the outcomes of IVF-ET. And the effect of co-culture largely depends on the in vitro activity of cumulus cells as well.

It is well known that there is close relation of the left atrial pathology to atrial fibrillation(AF) in patients with mitral valvular disease. To evaluate such relation is existed or not in the right atrium, the right atrial wall biopsy was performed in 31 patients with mitral valvular disease during valve surgery. The specimens obtained were interpretated by the pathologist who had no information about the patients. The specimens were graded according to severity of morphological change. In Grade I, the atrial myocardium is degenerated and has moderate fibrosis in it. Grade II shows the atrial myocardial layer of the atrium and severe degenerated with pre and postoperative heart rhythm. Four patients had Grade I change and 3 patients among them had pre and postoperative AF. Eleven patients had Grade III changes and 9 among them had pre and postoperative AF. The results show there is strong tendency that the patients with pre and postopeative AF had Grade III change in the right atrium and the relation of the right atrial pathology to AF is same as that of the left atrium.

A total of the 16 cases of rheumatic vavular heart desease were examined in order to compare fibrillatriy F wave with left atrial size and biopsy findings from October 1986 to April 1987 at the Ewha Womans University Hospital. The results were as follows : 1) Of the 16 patients, there were 5 males and 11 females. The mean age of the patients was 41.9+/-12.7 years old. 2) Among the 16 patients PTF-V1 was lesser than -0.04nn-sec, the left atrial size measured by M-mode echocardiography was 57.1+/-8.9mm. Inverse correlation between PTF-V1 and the left atrial size measured by M-mode echocardiography was observed(P<0.01). 3) No significant correlation between PTF-V1 and left atrial was found(P>0.01). 4) There was a tendency that the size of the left atrium was, the more degeneration, necrosis and fibrosis of the left atrial wall appeared through pathological findings.

The purpose of this study is to evaluate the correlation between the operative indications and the MRI findings in the herniated lumbar disc. We reviewed the lumbar spine MRI and medical records in the 158 patients of the herniated lumbar disc which were removed by open discectomy. We assessed the herniated lumbar disc in the MRI by the Steinmetz s classification and the operative findings with postoperative results at least 6 months. 170 levels of the operated lumbar discs in these patients consisted of protruded discs in 41 levels, extruded subligamentous discs in 91 levels, extruded transligamentous discs in 27 levels, sequestered discs in 11 levels. We recognized especially in the operated protruded discs that were combined with the lateral recess stenosis in most cases. Postoperatively, 139 patients (88%) had excellent and good results. We concluded that the clinical operative indications were correlated with the cases which were more severe than extruded subligamentous discs or protruded discs combined with lateral recess stenosis in MRI findings.
