Endotheline-1 (ET-1) is a potent vasoconstrictor peptide with 21 amino acid residues. ET-1 is thought to have a key role in vasoconstriction, and cardiac, renal, and endocrine actions of the peptide. Creatine Kinase(CK), also referred to as ATP-creatine-N-phosphotransferase, consists of either the B or M type. CK is found almost exclusively in muscle(MM), myocardium(MB), and brain(BB). It is to be an almost specific index of injury of myocardium and brain in hypoxic damage. I measured the ET-1, CK isoenzyme in neonates among asphyxia group (14 cases), as a control devide into two group. 1st group(birth weight (2500 g, n=9) and 2nd group (body weight 2500g, n=11). 1) There was no significant difference between asphyxia and control 1st, 2nd group during postnatal 24 hrs include cord blood on irET-1(p< 0.05). 2) There was significant difference between asphyxia and control 1 st, 2nd group during postnatal 24 hrs include cord blood on CK and CK and CK isoenzyme (p<0.001). 3) There was significant difference between asphyxia and control 1st, 2nd group on CK-MB and CK-BB proportion (p< 0.001). 4) There was significant difference between cord blood and postnatal 24 hrs on total CK level (P< 0.001).

Many previously described nuclear medicine procedures to assess glomerular filtration rate have some problems because numerous blood sample is to be taken and they don't measure each separate renal function. Gates described isotopic method for the measurement of global and unilateral GFR based on the fractional renal uptake of (99m)Tc-DTPA 2 to 3 minutes after its intravenous injection. We evaluated GFR using (99m)Tc-DTPA in 57 people according to Gates method and compared with creatinine clearance. A good correlation was observed between creatinine clearance and GRF calculated by Gates' formula with an r value of 0.9(P<0.05). And also the relationship between parameters of (99m)Tc-DTPA renal scan images and GFR was taken. They were significantly correlated with GFR calculated by Gates' formula : r value 0.66 between relative intensity of peak renal to peak aortic activity(pK/pA) and GFR, -0.42 between time between aortic and kidney peak(A-K) and GFR and -0.48 between parenchymal renal activity at 25 min compared to peak kidney activity(25K/pK) and GRF. In conclusion, the determination of GFR according to Gates' formula shows good and reproducible of GRF with rapidity and simplicity. And the parameters from the renal scan images can use to estimate the renal function.

We report a case of successful heart transplantation after 67 days of support with venoarterial extracorporeal membrane oxygenation (ECMO) in a patient who underwent surgery for type A aortic dissection and myocardial infarction complicated by irreversible myocardial damage and a deep sternal wound infection. During ECMO support, left heart vent and distal limb perfusion were performed. Mediastinitis was treated with mediastinal washout and irrigation. Multiple complications from peripheral ECMO were successfully managed.

Total hip replacement for adults with severe acetabular dysplasia presents a difficult problem because deficient bone stock and soft tissue contractures usually prevent sitting at the normal anatomic level. The rationales of high hip center are due to high failure rate of bulk structural weight bearing graft, good short-term result of hemispherical cementless acetabular component in revision surgery, high hip center but not lateral which does not adversely affect the biomechanics of the hip, and intimate apposition with viable host bone. We represented the short-term results of 21 total hip replacements with proximal placement of the acetabular cup than the anatomical position that is normally used. The mean duration of follow up was 18 months(range, 12-58 months) and the mean age of the patient was fifty-one years(range, thirty to sixty-seven years). Most of these hips had a major deficiency or defect of the acetabular bone stock. They had an aver- age Harris hip score of 47 points preoperatively and 90 points postoperatively. Roentgenographic measurements showed that the mean change in the height of the center of the hip postoperatively was only +6.6 millimeters and the mean change of horizontal location of them was 10 millimeters medial to the preoperative position. Postoperative complications included calcar fracture(1 case), trochanteric bursitis(1 case), postop- erative dislocation(1 case) and one case of radiological loosening of the acetabular component. The center of the hip in THR is not a crucial parameter with regard to the long-term stability of acetabular component, so our recommendation is to place the acetabular component at a more proximal but not lateral position if strong bone stock is available. But future studies of high hip center need to address femoral component longevity.

The syndrome of inappropriate ADH secretion is a disorder characterized by hyponatremia which results from water retention attributable to ADH release. The hallmark of SIADH is hyponatremia due to water retention, in the presence of urinary osmolality above plasma osmolality. The SIADH was initially described by Schwartz et al (1957). This syndrome, first recognized in patients with bronchogenic carcinoma, has now been observed in a variety of other illnesses. Recently, we encountered a 59 year-old female with small cell lung cancer, also she had SIADH. Thus, we present a case and review the literature on the subject.

Many features of the developing nervous system are visible from external observations of intact human embryos. In this study, a photographic atlas from the 4th to the 7th week after ovulation (Carnegie stages 10-18) is provided. The neural folds began to fuse at stage 10, and the rostral and caudal neuropore were closed during stages 11 and 12, respectively. The three primary divisions of the brain were distinguishable before closing of the neural tube. The five secondary brain vesicles were formed during stages 14-15. The development of the cerebellum and cerebrum were first observed at stages 14 and 15, respectively. The mesencephalic flexure was seen at stage 12, and the cervical flexure and pontine flexure at stage 14. After stages 18-19, it became increasingly difficult to identify detailed features of the brain from the surface. Results from this study will help to correlate the characteristic findings of the developing central nervous system of human embryos from stereomicroscopical and light microscopical observations and to locate the exact parts of the developing human brain for other purposes.
