PURPOSE: Prolonged fetal hypoxia stimulates erythropoiesis in fetal life and induces increased nucleated erythrocytes(NRBC) counts at the early newborn period. To evaluate the relationship between prolonged fetal hypoxia and neonatal intraventricular hemorrhage (IVH), and the prediction of neonatal IVH by neonatal NRBC. METHODS: We compared the daily courses of the absolute NRBC count in preterm new- boms at 34 weeks' gestation or earlier with(n=17) and without(n=20) IVH for 7 days of life. RESULTS: Absolute NRBC counts at birth were higher in neonates with IVH than in control neonates(2,499/mm3+/-3,748 and 412/mm3+/-272, respectively, P=0.0022). The cut-off value of 1,000/mm3 for absolute NRBC counts at birth showed the best parameter estimate of the predictive model for IVH at early newborn period with 100% of positive predictive value and 74.1% of negative predictive value. CONCLUSION: Prolonged fetal hypoxia inducing fetal erythropoiesis near labor is closely related to IVH at early newborn period. Thabsolute NRBC counts at birth is the very important predictable marker for the condition.

Acute infarcts of the anterior inferior cerebellar artery (AICA) territory are unusual. Furthermore incomplete AICA infarcts are perplexing because of its variations of vascular anatomy and inconsistent clinical features. We present a case with clinical features of AICA infarction, which consist of ipsilateral peripheral-type facial palsy, vertigo, and contralateral facial and upper limb sensory changes without motor weakness. The patient had hypertension and was a current smoker. The high signal intensity on inferior pontine tegmental area was found on MRI and the R2 interneuronal dysfunction was note on Blink reflex. The angiographic findings didn't show any focal vascular lesions, which is contrary to the pathogenesis of AICA infarction published previously. On the clinical ground, the present case reserves to attention in that patients with peripheral-type facial palsy should be properly evaluated and with thorough neurological examination and we could differentiate between the incomplete AICA infarcts such as Gasperini syndrome and Bell's palsy.

Ectopic thyroid is an uncommon embryological aberration characterized by the presence of thyroid tissue at a site other than in its usual pretracheal region. Usually it occurs along the path of descent of the developing thyroid primodium from the foramen cecum, commonest being lingual followed by sublingual and in the anterior midline of neck at, or below, the level of the hyoid bone. It is unusal for lingual thyroid to present simultaneously with another ectopic thyroid, so we report a case of 12-year-old girl who had multiple ectopic thyroid glands with goiter and compensated hypothyroidism diagnosed by computerized tomography in lingual and infrahyoid area.

PURPOSE: The purpose of this study is to evaluate the differences of the clinicopathological features and survival rates in gastric cancer according to the sex of the patients. MATERIALS AND METHODS: We reviewed 5,784 cases of gastric cancer patients who underwent laparotomy at the Department of Surgery, Seoul National University Hospital fmm Jan. 1986 to Dec. 1995. We have analyzed clinicopathologic features including tumor location, Bonmann type, depth of invasicm, lymph node metastasis, distant metastasis, TNM stage, histologic differentiation and survival rates according to the sex of the patients. RESULTS: The mean age of female patients was 52.4 years, which is lower than that of male, 54.8 years. There were no differences in tumor location, Borrmann type, depth of invasion, lymph node metastasis, distant metastasis, TNM stage of tumor between male and female. But there were some differences in histologic differentiation; well- and moderately differentiated cancers were more common in male and signet-ring cell cancers were more common in female. Female shows slightly better prognosis than male. But the prognosis of young female was poorer than that of young male. CONCLUSION: In gastric cancer patients, differences in histologic differentiation and more aggressive nature of the signet-ring cell cancer in female may affect the survival differences according to the sex.

The clinical value of the pre-(165 pts) and post-operative(149 pts) serum levels of carcinoembryogenic antigen(CEA) in 190 patients(pts) with colorectal cancer was investigated, who had a curative surgery and an abnormally elevated levels of CEA (> or=5 ng/ml) at Department of General Surgery, Chonbuk National University Hospital during 1989 to 1996. The results are as follows: 1) The preoperative positive rates of CEA level were 49(29.7%) of 165 patients, so preoperative CEA level measurement was no usefulness for screening test of colorectal cancer. The incidence of preoperatively elevated CEA levels in Dukes stages A, B, C, and D were 0, 28.6, 32.8 and 42.9% respectively, There was significant association between increased proportion of patients with preopertive serum CEA(> OR = 5 ng/ml) and the progressive stages of colorectal cancers(P<0.05). 2) There was no significant association between the frequency of abnormal CEA level and histologic differentiation of tumor. 3) The recurrence rate was 16.4% and 30.6% in patients with preoperative CEA < 5 ng/ml and > OR =5 ng/ml, respectively(p<0.05). 4) In patients with recurrence, the lymph node positive group(70.6%) was larger than the negative(29.4%)(p<0.05), and preoperative positive rate of CEA value was 44%. 5) The recurrence rate in Dukes stages A, Bl, B2, Cl, C2, and D were 0, 8.7, 12.7, 16.7, 32.3, and 90.0% respectively(p<0.01). 6) There was no significant association between the frequency of abnormal CEA level and location of tumor. 7) The recurrence rate was 12.3% and 65.7% in patients with postoperative CEA < 5 ng/ml and > OR = 5 ng/ml, respectively(p<0.01). 8) In patients with metastasis, postoperative positive rate of CEA level was 63%(p< 0.01).

Hypertrophic lichen planus is the most pruritic variant of lichen planus, which is characterized by verrucous plaques with variable amounts of scales on the lower extremities, especially the shins. Annular atrophic lichen planus is the most unusual variant of lichen planus, resulting from the combination of both annular and atrophic features in the same lesions. The active border of the lesion shows the typical histopathologic findings of lichen planus, whereas its atrophic center exhibits histopathologic features of regression. A 29-year-old man presented with intermittently pruritic, multiple plaques and papules on the right thigh for 3 months. At first, small, polygonal papules and verrucous plaques developed above the right knee. In a short time, atrophic and hyperpigmented macules with raised and annular borders appeared along the line of Blascho. Histopathologic examination of verrucous plaque and annular atrophic macule revealed hypertrophic and annular atrophic lichen planus, respectively. We, herein, report an unusual case of annular atrophic lichen planus associated with hypertrophic lichen planus along the line of Blascho.

Biohybrid artificial organs encompass all devices capable of substituting for an organ or tissue function and are fabricated from both synthetic materials and living cells. The viability of engineered tissue could be related to the viability of implanted cells. The system of viability assay for mammalian cell culture can be applied to the determination of cell viability for engineered tissue. This review explores various methods of cell viability assay which can be applied to the viability evaluation of engineered tissue. The major criteria employed in viability assays include survival and growth in tissue culture, functional assay, metabolite incorporation, structural altercation, and membrane integrity. Each viability assay method is based on different definitions of cell viability, and has inherent advantages and disadvantages. In order to be able to assess the viability of cells with one assay method, it is desirable to compare the viability measurements from various assays derived from different criteria.
