Growth Patterns of cranium measured directly as head circumference have been well documented. With the recent progress in CT, it is easy to measure the size and cross sectional area of the structure. The author chose themidvnetricular level of brain CT scan and measured the product of maximum anteroposterior and lateral dimension and cross sectional area. The age of infants ans children was 0 to 2 years old. The author obtained the following results through statistical analysis; 1. The maximum anteroposterior dimension and the cross sectional area were obtained through the computerized program of CT scanner. Using these measurements, monthly growth curve was obtained and which shows accelarated growth in the initial 12 months especially during the first four months, and followd by reduced rate of growth in the next 12 months. 2. Comparing the size of the calvarium between sexed,females' were somewhat larger than males', but there was no statistical significance. 3. Comparing the crosssectional area with the head circumference, high correlation was seen(correlation coefficient=0.96). Similarelationship was also seen between the product of cranial linear dimensions and the head circumference(correlationcoefficient=0.93). Also statistically significant relationship was noted between the cross sectional area and theproduct of the cranial linear dimensions(correlation coefficient=0.97). 4. Using the cross sectional area and theproduct of cranial linear dimenstions, monthly average value and the 95% significant range were obtained which canbe used as indices for the growth and development of cranium. Of these, the product of cranial linear dimensionscan eadily be measured by brain CT images, which may be useful on practical basis.

The development of leukemia during pregnancy is rare and difficult to diagnosis and treatment. Acute leukemias are among the most common malignant neoplasms of young women, but paradoxically, their incidence complicating pregnancy is cited to be 0.9 to 1.2 cases per 100,000. l'he signs and symptoms of acut:e leukemia may mask the signs and symptoms of early pregnancy. 'I'he occurrence of acute leukemia during pregnancy raises many therapeut,ic and ethical dilemmas because of the potential tetatogenic effects of chemotherapy and the danger of fetal wastage, in addition to the well-known problem of marrow suppression in the mother. We experienced a case where diagnosis of a woman at the 15 gestational weeks revealed acute lymphocytic leukemia and immediate treatment. as well as termination of pregnancy was made to prevent abnormal neonatal birth. We present this case with review of related literatures.

The expression of both constitutive and inducible forms of nitric oxide synthase (NOS) was investigated by immunohistochemical staining of formalin-fixed paraffin-embedded sections in normal and Listeria monocytogenes-infected brains of goats. In normal control goats, a small number of neurons showed immunoreactivity of both iNOS and nNOS, and the number of iNOS-positive neurons was higher than the number of nNOS-positive neurons. In natural listeriosis, listeria antigens were easily immunostained in the inflammatory cells of microabscesses. In this lesion, the immunoreactivity of iNOS in neurons was more intense than the control, but nNOS was not. In microabscesses, nNOS was weakly visualized in macrophages and neutrophils, while iNOS was expressed in macrophages, but not in neutrophils. These findings suggest that normal caprine brain cells, including neurons, constitutively express iNOS and nNOS, and the expressions of these molecules is increased in Listeria monocytogenes infections. Furthermore, inflammatory cells, including macrophages, expressing both nNOS and iNOS may play important roles in the pathogenesis of bacterial meningoencephalitis in goat.

Sphingolipids (SLs) are critical players in a number of cellular processes and have recently been implicated in a large number of human diseases, including atherosclerosis and cardiovascular disease (CVD). SLs are generated intracellularly in a stepwise manner, starting with the generation of the sphingoid long chain base (LCB), followed by N-acylation of the LCB to form ceramide, which can be subsequently metabolized to sphingomyelin and glycosphingolipids. Fatty acids, which are taken up by cells prior to their activation to fatty acyl-CoAs, are used in 2 of these enzymatic steps, including by ceramide synthases, which use fatty acyl-CoAs of different chain lengths to generate ceramides with different N-acyl chain lengths. Recently, alterations in plasma ceramides with specific N-acyl chain lengths and degrees of saturation have emerged as novel biomarkers for the prediction of atherosclerosis and overall cardiovascular risk in the general population. We briefly review the sources of plasma SLs in atherosclerosis, the roles of SLs in CVD, and the possible use of the “ceramide score” as a prognostic marker for CVD.

OBJECTIVE: The object of this study was to assess the accuracy of dipyridamole stress intravenous (IV) myocardial contrast echocardiography (MCE) using pulse inversion harmonic imaging and PESDA in the detection of perfusion defect in the patients with coronary artery disease in comparison with dipyridamole stress Tc-99m sestamibi SPECT. METHODS: Total 46 patients (29 males, mean age 64 years old) were consecutively enrolled. Patients with prior myocardial infarction were excluded. MCE and Tc-99m sestamibi SPECT were performed at the same day during rest and after 0.56 or 0.84mg/Kg dipyridamole infusion. Continuous IV infusion of PESDA (2-5 mL/min) was administered while obtaining triggered (1:1) end-systolic apical 2, 4 chamber and long axis views. Tc-99m sestamibi was injected 3 minutes after dipyridamole. Tc-99m sestamibi SPECT images were obtained one hour later. Coronary angiography was followed within two days in all patients. Tc-99m sestamibi SPECT images were matched to the sixteen segments of left ventricle according to American Society of Echocardiography for segmental comparison. Both images were analyzed visually. Results Using coronary angiography as the standard, MCE showed overall sensitivity of 70.7%, specificity of 95.8%, positive predictive value (PPV) of 87.8% and negative predictive value (NPV) of 88.5% in the detection of coronary atherosclerosis (70% stenosis). Tc-99m sestamibi SPECT showed sensitivity of 75.6%, specificity of 98.9%, PPV of 96.8% and NPV of 90.6%. The overall concordance rate between MCE and Tc-99m sestamibi SPECT for the detection of perfusion defects was 86.9% (Cohen's kappa value 0.63) according to the coronary territory and 86.8% (Cohen's kappa value 0.55) according to segmental analysis. CONCLUSION: Dipyridamole stress IV MCE using pulse inversion harmonic imaging and PESDA is feasible and comparable to Tc-99m sestamibi SPECT in identifying significant coronary stenosis and inducible myocardial perfusion defects in the patients with coronary artery disease. MCE using pulse inversion harmonic imaging seems to be a promising modality for assessing myocardial perfusion in the patients with suspected coronary artery disease.

Since the early discovery of H-reflex by Hoffmann in 1918 there have been a great number of articles in the literature suggesting its clinical used by Magladery in the early 1950. Our experiments about measurement of latent time in H-reflex were performed on 40 normal male adult(composed of medicos and medical officers) and 82 patients(lumbago 40, lumbar disc 42) admitted at CAFGH from January '79. to August '79. The result about normal adult are as follows: 1) The mean value and the standard deviation of the latent time in normal adult(height 171+/-5.14 cm) is 27.74+/-1.86 msec at right leg, 27.77+/-1.64 msec at left one respectively. 2) There may be a linear relationship between latency and the height of normal adult and the difference between right and left is revealed 0.15+/-0.19 msec. We compare the measurementon the 82 patients group with the normal adult experimental groups in addition literatures review.

Cesarean hysterectomy is associated with high risks of severe blood loss, postoperative complication, and maternal morbidity. This study was undertaken to identify the risk factors of cesarean hysterectomy and to reduce the postoperative complications and maternal morbidity. There were 6,362 deliveries between January 1992 and December 1996 at department of obstetrics and gynecology, Inchon Christian Hospital. 1'he results of this study were as follows, 15 cases of cesarean hysterectomy were performed during this period. Cesarean hysterectomy was performed in 10 cases (0.32 %) among 3178 cesarean deliveries and in 5 cases (0.16 %) among 3184 vaginal deliveries. The incidence of cesarean hysterectomy was 0.24 % (15/6,362). The age of patients ranged from 24 to 38 years old. The maternal mortality and morbidity were 0 % (0/15) and 86.7% (13/15), respectively. Indications for cesarean hysterectomy were uterine atony (53.3 %), uterine myoma with pregnancy (20.0 %), placenta accreta and/or increta(20.0 %), and placenta previa (6.7 %) in orders. The associated risk factors of cesarean hysterectomy were prior cesarean delivery (46.7 %) and placenta previa (6.7 %). The postoperative complications were anemia (60.0%), febrile morbidity (13.3 %), paralytic ileus (6.7 %), and wound disruption (6.7 %). We concluded that risk factors of cesarean hysterectomy were cesarean delivery, prior cesarean delivery, uterine myoma with pregnancy, placenta accreta and/or increta, and placenta previa and that sufficient fresh blood and careful prenatal care were needed in risk group of postpartum bleeding.

Etretinate(Ro 10-9359), an aromatic analogue of vitamin A acid, has been known to be effective in the treatment of psoriasis, Darier's disease, pityriasis rubra pilaris, ichthyosis, and palmoplantar keratoderma when administered orally. In this experiment, we compared the therapeutic and side effects between a group with high dose therapy(initially 75mg of etretinate a day) and an another group with low dose therapy(initially 40mg of etretinate a day). We also observed whether the pretreatment followed by combined treatment with vitamin E could potentiate the therapeutic effect as well as reduce the side effects of oral etretinate. This experiment comprised 102 moderate to severe psoriatic patients. The following results were obtained from this experiment. 1. Fifty-six among 92 patients(61%) who were treated with etretinate for more than 4 weeks showed good to excellent therapeutic effect. 2 The high dose therapy was more effective, but showed more side effects than low dose therapy. 3 Vitamin E did not potentiate the effect of etretinate. In low dose therapy, the pretreatment followed by combined treatment with vitamin E showed a tendency to reduce the side effects of etretinate.
