OBJECTIVE: To compare the clinical outcomes of intrauterine insemination (IUI) according to the catheter used. MATERIALS AND METHOD: From March 1998 to September 1998, total 95 infertile patients were included in this study. Patients were randomly allocated to TomCat group (n = 39) and Mackler group (n = 56) according to the catheter for insemination. The controlled ovarian hyperstimulation (COH) using luteal long protocol of gonadotropin releasing hormone agonist (GnRH-a) was used in all patients. Statistical analysis was performed using Student's t-test, Fisher's exact test, and x2 test as appropriate. Statistical significance was defined as p < 0.05. RESULTS: The total dose and duration of exogeneous gonadotropin required were similar between the two groups. There were also no significant differences in serum estradiol (E2) level, endometrial thickness and texture on the day of hCG administration between the two groups. However, the percentage of uterine souding due to failure of initial approach was significantly higher in TomCat group compared to Mackler group (23.1% vs. 0%, p < 0.01). The percentage of bleeding after IUI in TomCat group seemed to be higher than that in Mackler group (15.4% vs. 3.6%, p = 0.06), although there was no statistically significant difference between the two groups. There was also no significant difference in the clinical pregnancy rate per patient between the two groups. CONCLUSION: These results suggested that using Mackler catheter might be effective for IUI, especially for the patients with cervical factor infertility.

Reviewing the results of the blood cultures performed at Yeungnam University Hospital during 4-year-period through January, 1, 1984 to December 31, 1987, the following results were obtained. 1) Out of 8083 blood specimens cultured microorganisms grew in 582 specimens with positivity rate of 7.20%. Polymicrobial bacteremia was found in 16 patients. 2) Among 582 positive specimens, Gram-positive cocci grew in 189 specimens, and Gram-negative bacilli, in 393 specimens. Clinically significant microorganisms consisted of 82 Staphylococcus aureus, and 20 Streptococcus species in Gram-positive cocci group, 80 Salmonella typhi, 72 Escherichia coli, 72 Salmonella paratyphi A in Enterobacteriaceae, and 46 Pseudomonas cepacia, and 16 Pseudomonas aeruginosa in glucose non-fermenting microorganisms. 3) Increasing incidence of Serratia, Acinetobacter and Pseudomonas species as major nosocomial infection source is noteworthy. They showed increased tendency from 6.3% of 1984 to 17.7% of 1987 of total positive blood cultures. 4) High isolation rate of Pseudomonas species and Aeromonas hydrophila was noted in summer, while Salmonella typhi showed high prevalence from May to September and in January. 5) In susceptibility tests of isolated organisms, staphylococcus aureus was sensitive to basic antimicrobial agents except for ampicillin. The glucose non-fermenting microorganisms showed high resistance to basic antimicrobial agents in 32.2%. In conclusion, considering the relatively higher incidence of growth of Staphylococcus epidermidis than ideal level indicates that sampling technique should be improved. Secondly, all the hospital staffs in cooperation with Hospital Infection Committee are desirable to pay efforts to decrease the nosocomial infection.

We have found out the relationship of nanoemulsion containing nano vitamin C, E and propolis and gingival disease. We've confirmed effect of nanoemulsion through the experiment of in vivo and in vitro. We tested cell viability of gingival fibroblast cells by MTT assay and mRNA appearance of interleukin-1 beta, using mouse that was guided inflammation. Anti-microbacterial activity for Antibacterial effect's experiment was carried out by using S.aureus and E.coli. In addition, inflammation tissue has been observed with scanning electrical microscopy. In this study, expression of interleukin-1 beta was decreased after adding nanoemulsion containing nanovitamin C, E and propolis. We've also obtained good results from the test of Antibacterial effect against S.aureus and E.coli. Also, swelling of inflammation tissues observed by scanning electrical microscopy has gone down. In conclusion, we have gained confidence that nanoemulsion containing nano vitamin C, E and propolis has very high Antibacterial effect against bacteria in oral. And it made us guess that inflammation of gingival reduces after decreasing interleukin-1 beta. Thus, we expect that nanoemulsion containing nano vitamin C, E and propolis gives good effects to patient having gingival disease.

A study to evaluate the diagnostic significance of M. pneumoniae Infection by measurements of cold agglutinin and antimycoplasma antibody titers is performed with 191 pediatric patients who have visited Yeungnam University Hospital during the period through January to July, 1987. Forty eight of 191 cases made follow up tests feasible. The results obtained are as follows: 1. It is necessary to perform routine combined measurements of cold agglutinin and antimycoplasma antibody titers for the all pediatric pneumonia caser since a large proportion of pneumonia in children is caused by M. pneumonia. 2. For the diagnosis of M. pneumoniae Infection, measurements of cold agglutinin titer alone seems to be less significant than to check both cold agglutinin and antimycoplasma antibody titers. 3. The measurement of antimycoplasma antibody titer appeared to be more specific than cold agglutinin test in the diagnosis of M. pneumoniae Infection. 4. The present study urges the necessity of follow up study of cold agglutinin and antimycoplasma antibody titer for those who initially presented with normal titers in both tests, but are clinically suspected for M. pneumoniae Infection.

Perfluoroalkyl substances (PFAS) are widely used in industry and daily life due to their useful properties. They have a long half-life, accumulate in the body, and there is evidence that they are associated with biomarkers of lipid metabolism and liver damage. This may suggest non-alcoholic fatty liver disease (NAFLD) caused by PFAS. However, since there has been no study analyzing the relationship between PFAS and NAFLD in the entire population in Korea. We sought to confirm the relationship between serum PFAS concentration and NAFLD prevalence in Korean adults using the Korean National Environmental Health Survey (KoNEHS) cycle 4.

The changes in heart rate, systolic, mean and diastolic arterial blood pressure, and the plasma concentration of epinephrine and norepinephrine were measured before and thmughout the induction periods of anesthesia in 60 elective surgical patients in a randomized, double-blind manner to evaluate the effects of continuous intravenous infusion of esmolol for 1 minute at 500 ug/kg/min as a loading dose and for 4 minutes at 100 ug/kg/min as a maintenance dose. The control group (n=30) was given the continuous infusion of normal saline at the same volume-rate. During the study, anesthesia was maintained with N2O-O2-enflurane-vecuronium and controlled ventilation. In the esmolol group, statisticaUy, the heart rate at 1 minute after the intubation was less increased and systolic and diastolic pressure after 11 minutes were more decreased than the control group. And plasma norepinephrine concentration was elevated more than the control group at 3 minutes after the intubation. We concluded that the used infusion rate of esmolol blunted the hemodynamic changes following the laryngoscopy and endotracheal intubation but it is still needed to find the dosage for complete blocking the adrenergic response.

OBJECTIVES: To determine whether the body weight, body mass index (BMI), and basal serum level of LH, FSH, testosterone (T), dehydroepiandrosterone sulfate (DHEA-S) are related to the ovarian response to clomiphene citrate (CC) in patients with polycystic ovarian syndrome (PCOS). MATERIALS AND METHOD: From January 1996 to June 1997, total 57 patients with PCOS were enrolled in the present study. Women who had other infertility factors were excluded from our study. The ovulation induction using CC was used in all patients. The patients were grouped into 50 mg group, 100 mg group, and 150 mg group according to their daily CC dose. The patients were also grouped to ovulatory and non-ovulatory group. The body weight, BMI, arid basal serum level of LH, FSH, T, DHEA-S were measured in all patients on the 2nd or 3rd day of the menstrual cycle. Results were analysed with Student's t-test and Fisher's exact test. RESULTS: The body weight and BMI of the nonovulating group were significantly higher than those of the ovulating group in all groups (50, 100, 150 mg of CC). However, there were no significant differences of the level of LH and FSH between ovulating and nonovulating groups in all CC groups (50, 100, 150 mg). The level of T of nonovulating group was significantly higher in 50 and 100 mg of CC groups, but not in 150 mg group. The level of DHEA-S of the non-ovulating group is significantly higher in 50 mg group, but not in 100 and 150 mg groups. CONCLUSION: The body weight and BMI could be useful predictors of ovarian response to CC in patients with PCOS, and basal T and DHEA-S also might be useful in cases of low-dose CC treatment.
