Patients with migraine frequently have hypersensitivity to light, sound, and smell. In addition to these hallmark features of migraine, patients often describe vestibular complaints ranging from true vertigo to less specific symptoms of dizziness, unsteadiness, and head motion intolerance. Over the last two decades a number of studies have stressed the association of migraine with vestibular and ocular motor disorders. Migraine may be a most common cause of various forms of episodic vertigo, but definite diagnostic criteria for migraine related vertigo are still lacking. As migrainous vertigo is an evolving entity, terminology is confusing and generally accepted diagnostic criteria are not established. The interrelations of migraine and dizziness can be classified into seven categories: (1) vertigo as an aura of migraine-basilar type migraine, (2) episodic vertigo attack without typical temporal relationship to migraine headache-migraine equivalent, (3) vertigo/dizziness during migraine attack, (4) susceptibility of motion sickness in migraine patients, (5) CACNA1A gene mutation and migraine-familial hemiplegic migraine, episodic ataxia type 2, (6) well defined vertigo syndromes that are not caused by migraine but show a statistical association with migraine-Meniere's disease, BPPV, (7) non-vestibular dizziness in migraine patients-psychiatric comorbidity, antimigraine medication. Each part of categories will be discussed.

The intravenous pyelograms of 126 cases of ureteral stones were analized for study on changes in size,renocortical idex(RCI) and function of the affected kidney. The following results were obtained. 1. The size ofaffected kidney was increased in 45% of cases and decreased in 40% of cases. 2. The affected kidney showed anelevated RCI value as compared to the normal side. The mean value of RCI of the affected kidneys was 0.44 andnormal kidneys was 0.35. 3. The cases of upper ureteral stones most frequently showed urinary stasis. Theincidence of urinary stasis: hydronephrosis 61%, hydroureter 48%, nonvisualization 10%, and combinedhydronephrosis and hydroureter in 54% of the all cases.

OBJECTIVES: To investigate the effect of granulocyte colony stimulating factor (G-CSF) and granulocyte macrophage colony stimulating factor (GM-CSF) on expression of matrix metalloproteinase-2, 9 (MMP-2, 9) mRNA in mouse embryos. Materials and METHOD: From October 1997 to December 1998, morula stage mouse embryos were cultured for 48 hours with G-CSF and GM-CSF at concentrations of 0.1 pg/ml, 1 pg/ml, 10 pg/ml, 100 pg/ml, 1 ng/ml and 10 ng/ml, respectively. Embryos not treated with G-CSF or GM-CSF were served as control. Reverse transcription-polymerase chain reaction (RT-PCR) has been used to examine the expression of MMP-2, 9 mRNA in developed blastocysts. Following reverse transcription, strategically designed nested primers, optimized for specificity, were used for amplification from the cDNA equivalent of a single embryo. The products were then verified by restriction enzyme digestion and sequence analysis. Results were analyzed with Kolmogorov-Smirnov test and analysis of variance (ANOVA). The statistical significance was defined as p< 0.05. RESULTS: The relative quantities (relative volume x intensity) of MMP-2 mRNA expressed in embryos of all G-CSF treatment groups were significantly increased than in the control, especially in 10, 100 pg/ml and 1 ng/ml treatment groups. The relative quantities of MMP-2 mRNA in all GM-CSF treatment groups were also significantly increased than in the control, especially in 100 pg/ml treatment group. The relative quantities of MMP-9 mRNA of all GM-CSF treatment groups except 10 ng/ml group were significantly increased than in the control, especially 10, 100 pg/ml and 1 ng/ml treatment group. However, the relative quantity of MMP-9 mRNA was significantly increased in only 10 ng/ml G-CSF treatment group than in the control and other treatment groups. CONCLUSION: This study suggests that G-CSF and GM-CSF may increase the m-RNA expression of MMP-2 or 9 in mouse blastocysts with the concentration-specific manner.

PURPOSE: Recently, many alternative forms of non-surgical treatment modalities were devised for the management of BPH and one of them is transurethral radiofrequency thermotherapy(TURT). In this study, we investigated the long term efficacy of TURT. MATERIALS AND METHOD: A total of 132 patients with symptomatic BPH were treated in a single session with TURT using Thermex-ll(47.5 degrees C, 150minutes) and 88 patients who were available to follow-up for more than 6 months after TURT were enrolled in this study. Among them, 65 patients were available to follow-up for more than 2 years. The baseline and post-treatment mean symptom score(Madson-Iversen), maximal flow rate(MFR), residual urine volume and prostate volume were compared. Improvement was defined as a reduction of more than 50% in at least one of two parameters(symptom score and maximal flow rate). We also investigated whether other treatment modalities were selected in 2 years after TURT. RESULTS: At 3 months follow-up, improvements were observed in 59.1%(52/88), and at 6 months 54.5%(48/88). However, improvements in both symptom score and maximal flow rate at 3 and 6 months after treatment were only 27.3% and 20.5%, respectively. Among 65 patients who were available to follow-up for more than 2 years, 27 patients(41.5%) had undergone transurethral resection of the prostate either with(19) or without medication(8). 28 patients (43.1%) received medical therapy such as alpha blocker during the last two years after TURT. The post-treatment values of the 10 patients who had not received adjuvant therapy were not significantly different from those at baseline. CONCLUSIONS: Although thermal treatment for BPH is an alternative option with minimal complication in selected symptomatic patients who are not clear candidates for surgery or high-risk patients, the long term effect of TURT is not sufficient to relieve the obstructive and irritative symptoms of BPH.

OBJECTIVES: To examine the in vitro interactions of blastocyst attachment using type I collagen. MATERIALS AND METHODS: ICR mice were used and follicular growth was stimulated by pregnant mare serum gonadotropin and human chorionic gonadotropin. On day 4 of pregnancy, the uteri were removed and blastocysts were flushed. Mixtures of 1mL sterile water, 0.5mL DMEM, 2mL type collagen solution and 0.5mL 0.1M NaOH were prepared and transferred to an incubator where the collagen solution polymerized. Blastocysts were transferred to dishes previously coated with type I collagen. CMRL 1066 was used as the basic culture medium. It was supplemented with 1mM glutamine and 1mM sodium pyruvate plus 50 IU/ml penicillin and 50 mg/ml streptomycin. During the first 4 days the culture medium was supplemented with 20% fetal calf serum and thereafter with 20% heat inactivated human cord serum. All blastocysts were initially cultured for 2 days without media change. After 2 days, fresh medium was renewed daily. The stages of embryo growth were examined and recorded everyday under a dissecting microscope and classified according to the standard in vivo criteria set forth by Witschi. RESULTS: By 48h, nearly all blastocysts had attached to the surface of collagen pad. Following adhesion to the collagen pad, the blastocysts maintained their 3-dimensional integrity in contrast to control. The embryos in collagen pad were not flattening and kept polarity and spherical shape during culture. The polar trophoblast invaded the type I collagen downward unlike the horizontal growth in control. In the developmental stage of mouse blastocyst, there were significant differences between control and type I collagen group during day 4 and 5 culture. CONCLUSION: Blastocyst development was better in type I collagen group than control. Therefore, in vitro culture study using type I collagen could provide improved model for the establishment of blastocyst implantation study.

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.
