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.

BACKGROUND: Total intravenous anesthesia with propofol can cause respiratory depression and apnea especially during induction of anesthesia. To study the possibility of reversal of respiratory depression during anesthesia with propofol, pretreated with nabuphine or not, the respiratory effects of doxapram to spontaneously ventilating patients were investigated. METHODS: Patients were divided into 4 groups - saline-propofol-saline group (SPS), saline-propofol- doxapram group (SPD), nalbuphine-propofol-saline group (NPS), and nalbuphine-propofol-doxapram group (NPD). After saline or nalbuphine pretreatment, anesthesia was induced with propofol and then doxapram or saline was intravenously injected. Apneic time interval, blood pressure, heart rate, respiratory rate, minute ventilation, end tidal CO2 partial pressure and oxygen saturation were measured in every minutes during induction of anesthesia. Percent changes of each values were compared. RESULTS: There is no differences in apneic time intervals in each groups. The percent change of first minute ventilation in SPD group after doxapram injection unchanged significantly compared with those depressions of SPS, NPS and NPD group (p<0.05). Respiratory rates increased in SPD and SPS groups after laryngeal mask insertion. There is no differences in minute ventilation, respiratory rate and end-tidal CO2 concentration between nalbuphine pretreated groups regardless of doxapram injection. CONCLUSIONS: Doxapram has effect in increasing minute ventilation after propofol induction within first few minutes, but it cannot reverse respiratory depression during propofol induction pretreated with nalbuphine.

This study was conducted to determine the level of inflammatory cytokines in the cerebrospinal fluid (CSF) of patients with meningitis. All the CSF of the patients were examined by Gram and acid-fast stain, culture, and PCR for Mycobacterium tuberculosis and Mycoplasrma spp..The levels of sugar, protein and leukocytes count were also evaluated in the CSFs. Concentrations of Interleukin (IL)-1B, IL-6, IL-8, tumor necrosis factor (TNF)-a in the CSF were evaluated by the ELISA kit (Genzyme, USA). General bacteria, tubercle bacilli, and Mycoplasma spp. were not detected with stain and culture methods, but, Mycoplasma spp. was detected by PCR method from four (6.3%) patients with meningitis. The mean CSF concentration of IL-1B, IL-6, IL-8, and TNF-cx in the control group were 0.6+/-0.2, 896.8+/-107.6, 50.1+/-5.1, and 4.8+/-1.4 pg/ml, respectively. The mean CSF concentration of IL-1B, IL-6, IL-8, and TNF-a in the patients with aseptic meningitis were 3.8+/-0.6, 1261.6+/-144.3, 466.7+/-42.3, and 10.8+/-2.0 pg/ml, respectively. The mean CSF concentration of IL-1B, IL-6, IL-8, and TNF-a in the patients with mycoplasmal meningitis were 10.2+/-8.1, 1979.5+/-133.8, 459.7+/-96.4, and 17.5+/-5.1 pg/ml, respectively. There were significantly differences in the levels of IL-1B, IL-6, IL-8, and TNF-a between control and patients with aseptic meningitis or Mycoplasmal meningitis (each p<0.001). These results suggest that increased levels of IL-1B, IL-8, and TNF-a could be higly suggestive of meningitis.

We investigated the occurrence of color vision loss in 70 organic solvent mixtures exposed workers and in 47 controls. Color Vision was assessed with a color arrangement test designed to identify the defective color sense, the Han Double 15-Hue Test. The results of the test were no significant difference between exposed workers and controls in the proportion of subjects who committed one or two errors. Quantitative analysis, using color confusion index(CCI), showed no signifiant difference between exposed workers and controls. A significant linear correlation was present between age and CCI in both exposed workers(CCi=0.0056age + 0.94; r=0.23; p<0.05) and controls(CCI=0.0066age + 0.86; r=0.33; p<0.05). Qualitative analysis of the patterns on the hue circle showed that the prevalence of acquired dyschromatopsia was 21% in both and no significant difference. Multiple regression analyses showed that age was significantly related to color vision loss. These results did not provide evidence of a relationship between organic solvents exposure and incidence of color vision loss. In field studies for monitor the people at risk of the acquired color vision loss involving low-dose organic solvents exposed workers, both quantitative and qualitative information should be considered.

STATEMENT OF PROBLEM: Proper proximal contact is important for maintaining and stabilizing the dental arch. However, the proximal contact strength (PCS) is not a constant value and can be affected by a variety of factors. PURPOSE: This study examined the influences of postural changes on the posterior PCS. MATERIAL AND METHODS: Twelve adults with a normal occlusion and had not undergone prosthetic treatment or proximal restoration were participated in this study. A metal strip was inserted into the proximal surface and removed at a constant velocity. The contact strength was measured in every contact point between canine to second molar in both arches. The PCSs were obtained initially in the upright position, secondly in the supine position and finally in the upright position again. All measurements were repeated after a 2 hour period. Statistical analysis was carried out using the Friedman test (P < .05). RESULTS: Generally, a decrease in PCS occurred when the posture was changed from the initial upright to supine position, while it increased when the posture was changed from the supine to upright position. A significant change was observed in all areas except for between the canine-first premolar in the maxilla and between the first molarsecond molar in the mandible areas. CONCLUSION: The posterior PCS, which dentists generally believe to be a static feature of occlusion, is affected significantly by posture.

OBJECTIVE: To analyze the efficacy of intracytoplasmic sperm injection (ICSI) for totally unfertilized oocytes by the conventional insemination during in vitro fertilization and embryo transfer (IVF-ET) METHODS: From March 1996 to April 1998, 15 couples who experienced total fertilization failure after conventional IVF without severe male factor infertility in semen analysis were evaluated. Fertilization were assessed by the presence of 2 pronucleus (PN) after 14-16 hours of conventional insemination. All unfertilized oocytes were reinseminated by ICSI and checked for signs of fertilization between 6-10 hours after ICSI. The embryos with fertilization and development were transferred to the uterine cavity and the outcome was analyzed. RESULTS: Total numbers of unfertilized oocytes were 120, and total numbers of oocytes injected on day 1 using ICSI were 102. Total numbers of oocytes with normal fertilization after ICSI were 74 and mean fertilization rate of 71.1 +/- 24.0% was obtained. The numbers of embryos transferred was 3.6 +/- 1.7. The biochemical pregnancy rate was 13.3% (2/15) and the clinical pregnancy rate was 6.7% (1/15) per cycle. CONCLUSION: ICSI to totally unfertilized oocytes by conventional insemination technique during IVF-ET on the next day of oocyte retrieval seems to be a relatively successful mean and afford a chance of pregnancy to the infertile couples whom the ET could not perfomed to because of total fertilization failure."

OBJECTIVE: To evaluate whether the basal serum luteinizing hormone (LH) levels in the presence of normal serum follicle stimulating hormone (FSH) are useful as a prognostic indicator of ovarian response to controlled ovarian hyperstimulation (COH). METHODS: From January 1997 to January 1999, 91 infertile women with tubal factor who had undergone in vitro fertilization and embryo transfer (IVF-ET) were enrolled in the present study. COH was performed using long protocol of gonadotropin-releasing hormone (GnRH) agonist. All patients included in this study had blood samples drawn on cycle day 2 or 3 prior to COH for measurement of basal FSH and LH. Women who had other infertility factors or high basal FSH levels (> or = 8.5 mIU/ml) were excluded from this study. The results of COH and IVF-ET were compared between two groups according to the level of basal LH (low LH group [< 3mIU/ml] vs. control group [> or = 3mIU/ml]). RESULTS: Patient's characteristics were comparable in both groups except basal LH level. The number of ampules and duration of exogenous gonadotropins required were significantly higher in the low LH group than those in the control group (p<0.001; p<0.005, respectively). The number of follicles > or = 14mm diameter on the day of human chorionic gonadotropin (hCG) injection was significantly less in the low LH group than that in the control group (p<0.001). The serum estradiol level on the day of hCG injection was also significantly lower in the low LH group, with 1115.5 +/- 380.9 pg/ml compared with 1340.6 +/- 403.0 pg/ml in the control group (p<0.005). There were significantly lower numbers in oocytes retrieved, oocytes fertilized and embryos frozen in the low LH group than those in the control group (< 0.001; < 0.001; <0.005, respectively). However, there was no difference in the fertilization rate between the two groups. The clinical pregnancy rate per cycle seemed to be lower in the low LH group, but the difference did not achieve significance (26.2% vs 39.7%). There were no differences in the miscarriage rate and multiple pregnancy rate between the two groups. CONCLUSION: This study demonstrates that the low basal LH levels ( < 3 mIU/ml) could be predictive of low ovarian response to COH and poor IVF results.
