Three groups of patients with newely diagnosed hypertension, or with hypertension not optimally controlled by previous treatment, completed a comparative study on the effects of Dihydrochlorothiazide, propranolol, and prazosin on plasma lipids after three months therapy. The drugs showed equipotent antihypertensive effects(P<0.01). Dihydrochlorothiazide administration was associated with a significant elevation of total cholesterol(42%, P<0.05), and triglyceride(8.1%, P<0.01). Changes of HDL-C(5.1%), LDL-C(3.3%), and cholesterol ratio(-4.8%) were not significant. Propranolol administration was associated with significant elevation of total cholesterol(3.8%, P<0.05), triglyceride(14.5%, P<0.005), and LDL-C(5.6%, P<0.005). Reduction of HDL-C(-7.8%, P<0.05) and cholesterol ratio(-14.7%, p<0.005) was also statistically significant. Prazosin administration was associated with significant decrease in total cholesterol(-6.6%, P<0.005), triglycride(-9.6%, P<0.005), and LDL-C(-11.7%, P<0.005), and significant elevation of HDL-C(10.6%,P<0.005) and cholesterol ratio(24.2%, P<0.005) was noted.

BACKGROUND: Recently, missense mutation of the B3-adrenergic receptor gene has been shown to be associated with early onset of type 2 diabetes, abdominal obesity and an increased capacity to gain weight. This study was performed to investigate the effects of Trp64Arg mutation in the B3-adrenergic receptor gene on body fat distribution and weight loss in obese subjects. METHODS: Determination of the B3-adrenergic receptor gene mutation with restriction enzyme digestion method, anthropometry, various biochemical studies, including oral glucose tolerance test were performed in 99 obese and 35 control subjects. Body fat distributions were also evaluated by computerized tomography before and after weight-reduction program. RESULTS: I) There were no differences in the frequencies of Trp64Arg mutation in the B3-adrenergic receptor gene between obese and control subjects (15.2 vs 12.9 %). 2) The obese subjects with Trp64Arg mutation had higher waist to hip circumference ratio(WHR) (0.93 +/- 0.05 vs 0.87 +/- 0.04, p<0.001), visceral fat area (115.0 +/- 25.9 vs 86.4 +/- 41.4 cm, p=0.01), but decreased plasma free fatty acid (618.0 +/- 163.1 vs 817.5 +/- 248.2 pEq/L, p=0.001), and triglyceride level (118.7 +/- 36.2 vs 158.4 +/- 105.8 mg/dL, p=0.015) than those without mutation. 3) The obese subjects with Trp64Arg mutation had smaller decreases in weight (-3.4 vs -5.1 kg, p<0.001), body fat content (-2.1 vs -3.8 %, p<0.001), WHR (-0.01 vs -0.03, p=0.025), and abdominal fat masses (total, subcutaneous, and visceral fat) after weight-reduction program than those without mutation. CONCLUSION: Trp64Arg mutation in the B3-adrenergic receptor gene might be one of genetic loci contributing to central obesity and a predictor of difficulty in losing weight in obese subjects.

OBJECTIVE: The objective of this study was to examine the effect on development of mouse preimplantation embryos in culture media with different composition of energy sources in vitro culture. METHODS: Two hundred and seventy one two-cell embryos were cultured in four different culture system for 96 hours. Group I (n=61) was cultured in DMEM-G (DMEM with glutamine) only, groupII (n=64) was cultured in DMEM-GGP (DMEM with glutamine, glucose and pyruvate) only, group III (n=72) was cultured for 48 hours in DMEM-G and then transferred to DMEM-GGP and group IV (n=74) was cultured for 48 hours in DMEM-GGP and then transferred to DMEM-G. Development of embryos in each group was observed every 24 hours. RESULTS: After 24 hours, the rate of development > or = 3-cell was significantly higher in groupII (87.5%) and IV (86.5%) compared with group I (59.0%) and III (62.5%). After 48 hours, the rate of development into > or = morula stage was significantly higher in GroupII (79.7%) and IV (86.5%) compared with group I (34.4%) and III (37.5%). After 72 hours, the rate of development into blastocyst was significantly higher in group IV (74.3%) compared with group I (49.2%) and III (45.8%). After 96 hours, the rate of development into > or = expanded blastocyst was significantly higher in group IV (70.3%) compared with group I (32.8%),II (53.1%), and group III (40.3%). CONCLUSION: Mouse preimplantation embryos development was the most effective in culture system with DMEM-GGP for 48 hours and then transferred to DMEM-G.

OBJECTICES AND METHODS: The purpose of this study was to examine availabilities of stop-signal task as a screening test for ADHD and as a research tool. Stop-signal task was applied to 40 ADHD patients and 18 normal children. Followings are the results of this study. RESULTS: There were significant differences between ADHD group and control group in ZRFT, mean delay x block and primary-RT of stop-signal task performance(p<0.05). There was no significant difference in results of continuous performance test. SSRT of stop-signal task had significant correlation with hit reaction time of continuous performance test, and primary-RT and primary-SD with attentiveness and hit reaction time of continuous performance test. There was no significant correlation between scores of ADDES-HV and stop-signal task performance. In change of primary-SD according to intelligence, primary-SD decreased as intelligence increased but made plateau after IQ 110, and in change of SSRT according to age, SSRT decreased as intelligence increased but made plateau after 10 year-old. In discriminant ability, mean delay x block and primary-RT showed highest discriminant ability (each 75%). In addition P-inhibit showed 63.89%, SSRT showed 58%, ZRFT showed 67%, and primary-SD showed 58% in discriminant ability. There was no significant difference in stop-signal task performance between ADHD with hyperactivity and ADHD without hyperactivity. CONCLUSION: In this point of view, stop-signal task was proved to be a useful research tool for attention deficit hyperactivity disorder as well as useful screening test tool.

Regional anesthesia for non-obstetric surgery in parturients is a method to decrease patient and fetal risk during general anesthesia. Thoracic interfascial nerve block can be used as an analgesic technique for surgical procedures of the thorax. The Pecs II block is an interfascial block that targets not only the medial and lateral pectoral nerves, but also the lateral cutaneous branch of the intercostal nerve. Pecto-intercostal fascial block (PIFB) targets the anterior cutaneous branch of the intercostal nerve. The authors successfully performed a modified Pecs II block and PIFB without complications in a parturient who refused general anesthesia for breast surgery.

Femur intramedullary nailing can be one of the most predictable procedures in orthopedic traumatology. The advantage of this method is that the fracture site does not have to be widely exposed for reduction, which can minimize soft tissue damage. For this reason, the incidence of complications related to hematoma has been rare. We experienced only one case of sciatic nerve palsy due to hematoma after intramedullary nailing; the patient was receiving an anticoagulant therapy. Therefore, we report this case with literature review.

OBJECTIVE: This present study was conducted to examine the effects on in vitro growth of pre-antral mouse follicles by thecal-stromal cells attached to around the follicular membrane in culture medium without hormones. METHODS: Pre-antral follicles (100-130 micro meter) used in our studies were isolated mechanically by fine 30 G needles attached to 1 ml insulin syringe from mice ovaries of 20-25 days old female ICR strain. Isolated pre-antral follicles were divided into three groups by attached status of thecal-stromal cell layers to follicular membrane. Follicular Initial diameters of group I was 112.5 (mean) +/- 6.2 (SD) micro meter (n=31), group II was 112.8 +/- 7.8 micro meter (n=23), and group III was 115.1 +/- 6.5 micro meter (n=27). Divided pre-antral follicles were washed in fresh Ham's F-10 medium and cultured in 20 micro liter droplets of DMEM with glutamine, glucose and pyruvate under mineral oil on the 60 mm culture dish. All experimental media were supplemented with 10% FBS without hormones. Media were exchanged wholly by fresh media every 2 days in culture. Diameters of intrafollicular oocytes and cultured pre-antral follicles were measured using an precalibrated cross ocular micrometer at X200 every day during 6 days in vitro culture. Results were considered statistically significant when p value was less than 0.05 using Student's t-test. RESULTS: The mean and standard deviation (SD) of initial diameters of pre-antral follicles was 113.5 +/- 2.2 micro meter in three groups. Follicular growth rate of group III was significantly (p<0.05) higher in whole culture periods than group I and group II. Rate of follicular growth between group I and group II were not significant difference in culture for 1 to 3 days. However, group II was significantly higher than group I in culture for 4 days. Diameters of grown follicles for 6 days was 155.2 +/- 18.7 micro meter, 196.9 +/- 24.1 micro meter and 284.2 +/- 47.6 micro meter in group I, group II and group III, respectively. Growth rate of intrafollicular oocytes between three groups were not difference and revealed to continuous growth patterns in whole culture periods. Follicular diameter after culture for 7 days were not measured because of disruption of follicular structure or outgrowth of granulosa cells. CONCLUSION: Pre-antral follicles were grown very well in DMEM medium without hormones. Thecal- stromal cells attached to the surface of follicular membrane has acted effectively in vitro growth of follicles.
