Korean Journal of Anatomy 1997;30(3):235-242
Morphological characteristics of human embryos of Carnegie stage 17 were described. The crown rump length of these embryos were 11.7-13.6mm. These embryos were characterized externally by ventrally directed nasal pits, 6 distinct auricular hillocks, finger rays in the hand plate, digital plate at the lower limb bud, herniation of a part of midgut through umbilical cord, and internally by the partial fusion of ventral and dorsal pancreas, prominent nasal sac which is not open to primitive oral cavity, formation of segmental and some subsegmental bronchial buds, branching of metanephrotic pelvis, crescent-shaped lens cavity, and imminent semicircular ducts.

Although several kinds of instrumentation systems are available for the transpedicular screw fixation in the treatment of spondylolisthesis, the clinical results and the difference between them remdins unclear. In order to study the feasibility of Zielke instrumentation system for that purpose, the author analysed the clinical results of 73 patients with mild or moderate degree of spondylolisthesis who were instrumented with the systems and followed up 25 months in average(Min. 12Ms). The results between the groups with different rod thickness in the system, 3.2mm(20 patients), 4mm(33 patients) and 5mm(20 patients), were compared to study the most appropriate thickness. Reduction of the deformity were done by aid of temporarilly applied Harrington system in 3.2mm group. Inlayed reduction potential coming from the jointing mechanism was utilized in the cases with less than 30% of slippage in 4 and 5mm group. Percentage of slippage was changed from 20% preoperatively, to 4% postoperatively and 6% at the end of follow up. The methods of fusion after reduction and fixation were anterior in 25 and posterolateral in 48. Bony fusion was achieved in all but one with pathological spondylolisthesis. Rod failures were observed in two of 3.2mm and one of 4mm group, and loosening of the joint were developed in three of 5mm group. Clinically, 93% of the patient showed excellent and good results at the end of follow up. From the results, we concluded that the instrumentation is a efficient method of treatment with several advantages in the reduction capacity and the stability of fixation. However, this system has several points in its mechanics that needs to be improved.

Results from two in vitro assays, Pharmacia CAP system(CAP) and fluoroallergosorbent test(FAST), for detecting serum specific IgE to three allergens, mugwort, Derraatophagoides pteronyssinus, and eat epithelium, were compared with skin prick test(SPT) results in 53 atopie dermatitis patients with positive SPT and 25 non-atopic controls. Using SPT results as the reference standards, CAP achieved higher sensitivity than FAST in determination of three allergens. CAP for measuring total IgE and eosinophil cationic protein(ECP) was also compared with FAST and ECP radioimmunoassay(RIA), respectively. In comparison of two assays for total serum IgE, the values obtained with CAP were significantly higher than those with FAST. In comparison of CAP and RIA for measuring ECP, the values obrained with CAP were significantly higher than those with RIA and the differences between ECP values of two assays were significant in high ECP group(>8.3 micro gram/1). These results suggest that CAP is the preferred test and seems to be more appropriate method for detection of specific IgE and ECP in patients with allergic digeases.

Spinal epidural hematoma is a rare complication of epidural anesthesia and most commonly associated with intraoperative or postoperative anticoagulant administration. We describe the case of an acute thoracolumbar epidural hematoma at the T12-L4 level complicated by cauda equina syndrome, which occurred after placement of spinal epidural catheter for anesthesia and anticoagulant therapy for acute myocardial infarction developed postoperatively. In our experience, the spinal epidural catheterization and anticoagulant therapy may potentially increase the risk of epidural hematoma formation.

Takayasu's arteritis is a chronic vasculitic disease of the aorta, its major branches and the pulmonary arteries, resulting in stenosing, occlusive or aneurysmal lesion. While the precise etiology of Takayasu's disease is unknown, an autoimmune mechanism or active tuberculous inflammation have been suggested. It is more common in young oriental women but has a rare incidence in children. We experienced a case of Takayasu arteritis type IV in an 8years old girl. The diagnosis was made by physial examination and digital substraction aortography(DSA) which showed narrowing of left common carotid artery, right subclavin artery and left renal artery. The perfusion defect at posterior segment of right upper lobe was noted in lung perfusion scan. Medical treatment and percutaneous transluminal angioplasty(PTA) were performed. In addition to case report, a brief review of literature was added.

To study the effect of indomethacin treatment on the reactivity of contact hypersensitivity and discuss relevant mediators which could affect contact hypersensitivity, the following items were evaluated: the change in the plasma concentration of prostsglandin E following indomethacin treatment; the change of contact hypersensitivity following indomethacin treatment. The results ore summarized as follows: 1. The plasma level of prostaglandin E in indomethacin treated mice decreased. 2. The contact hypersensitivity of indomethacin treated mice was depressed. Considering the suppression of contact hyper sensitivity by indomethacin treatment, the metabolites of cyclo-oxygenase such as prostaglandin E may be the possible mediators of induction of contact hypersensitivity.

A survey of intestinal parasites was performed in South Vietnam. Samples were collected from 717 Vietnameses, 1,933 U.S. Forces, 433 stool specimens of Korean Troops in South Vietnam. And 114 of Korean Army patients in home land were also examined as a control. Findings were discussed with others and summarized as follows: A parasitic rate, incidence in general, was 44.8 %. Koreans in South Vietnam showed 82.4 % of infection rate, Vietnamese 64.6% and U.S. Forces 26.1 %. Korean home patients revealed 93.9 %. Following 10 species of helminths ova and 5 kinds of protozoa were found: Ascaris lumbricoides, Hookworm, Trichocephalus trichiurus, Strongyloides stercoralis, Trichostrongylus orientalis, Enterobius vermicularis, Metagonimus yokogawai, Clonorchis sinensis, Hymenolepis nana, Taenia sp., Entamoeba histolytica, Entamoeba coli, Endolimax nana, Giardia lamblia and Trichomonas hominis. The incidence of Ascaris lumbricoides among Koreans in South Vietnam was 15.9 %, much less than Korean home patients. The infection rate of A. lumbricoides in Saigon residents was 47.2% but in Chulai 36.8% and in Quinhon 35.8 %. Trichocephalus trichiurus was most frequently found in Koreans. Quinhon residents showed 78.7 % positive in hookworn infection and Chulai 24.7 %. In Saigon, on the contrary, infection rate was only 3.1 %. No Strongyloides stercoralis, but two cases of Trichomonas hominis were found among Koreans in South Vietnam. U.S. Forces showed higher incidences than Koreans and Vietnameses in the incidences of Entamoeba histolytica and Endolimax nana. Most of the U.S. Forces revealed single infection. Korean home patients showed the highest per centage of polyparasitism. Non-autochthonous infections in Korea could not be found among Koreans in this survey.
