Liesegang rings (LRs) are peculiar structure of periodic precipitation zones from supersaturated solution in colloidal system. LRs are formed by a process referred to as "the Liesegang phenomenon". Here we describe LRs in renal hemorrhagic cyst from the donor kidney of a 59-year-old man. His general condition was good. Abdominal ultrasonography revealed a simple cyst in the left kidney. After donor nephrectomy for renal transplantation, a 3x2 cm sized cyst containing the brownish necrotic fluid was noted in the upper pole of left kidney. Frozen section from the relatively thickened cystic wall was performed. During frozen section examination, round concentric rings with double-layered outer wall, striations and amorphous central nidus admixed with the foamy macrophages were found and the lesion was originally interpreted as xanthogranulomatous inflammation with unusual crystalline structures in the cytoplasm of macrophages or freely in the interstitium. Macrophages with calcium crystals or malakoplakia were also considered at that time. Additional specimen for the permanent sections showed a simple hemorrhagic renal cyst with areas of small or large aggregates of LRs along the cyst wall. Multiple round ring-like structures ranging from 11 to 42 micrometer in diameter had uniform, pale eosinophilic, radially striated double wall. Histochemical and immunohistochemical stainings for iron, calcium, mucopolysaccharide, amyloid, cytokeratin were negative in these structures. They were highlighted by CD68 immunostaining as well as PAS and Masson's trichrome stainings. Awareness of Liesegang phenomenon in cystic lesions will decrease the possibility of erroneous diagnosis as another type of pathologic process, such as parasitic worms or eggs.

PURPOSE: Neonatal jaundice is one of the most common problems in our country leading to hospitalization. Agar is low cost, low risk, and easily fed orally; it can bind bilirubin in the intestine, decreasing its enterohepatic circulation, thereby decreasing serum bilirubin levels. At present, however, the effectiveness of agar in the prevention and treament of neonatal jaundice is quite conflicting and controversy. Recently we have read Caglayan's 'Superiority of Oral Agar and Phototherapy Combination in the Treatment of Neonatal Hyperbilirubinemia'. The result was very hopeful and attractive enough, and which gave us a motivation to study if it was really of value. METHODS: From May 1995 to April 1996, a total 50 term neonates admitted in nursery of Dong-Eui Medical Center with the capillary serum bilirubin levels greater than 10mg/ dl were enrolled in the study. Those with pathologic causes and breast fed infants were all excluded. The neonates were randomly devided into two groups; 25 of conventional phototherapy alone (P group) and 25 of oral agar plus conventional phototherapy combination (A+P group). The study was terminated when the capillary serum bilirubins were decreased to 8mg/dl. Pastagar B (Pasteur Institute 64946) 500mg in 10ml distilled water were fed four times a day using 10ml syringes prior to bottle feeding. Capillary serum bilirubin levels were measured daily at 10:00 a.m. with heel pad samples. Daily stool frequency and adverse effects of treatment were observed closely. RESULTS: 1) The decrement of the serum bilirubin levels at first 24 hours of therapy was significantly different between P and A+P groups showing as 1.7+/-1.2 and 2.4+/-1.0mg/dl respectively (p<0.05). 2) Mean time for bilirubin to decrease to 8mg/dl was shorter in A+P group than in P group showing as 45.7+/-20.8 and 57.5+/-32.3 hours each other, but those differences were statistically insignificant (p>0.05). 3) No adverse effects such as rashes or abdominal pains were observed during treatment. Differences of mean stool frequency were significant between P and A+P groups showing as 3.7+/-1.2 and 4.7+/-2.0 times per day respectively (p<0.05). CONCLUSION: The agar plus conventional phototherapy combination was superior to conventional phototherapy alone at first 24 hours of therapy in neonatal hyperbilirubinemia, but further more careful researches would be necessary for using it routinely in the treatment of neonatal hyperbilirubinemia in future.

PURPOSE: An excess of GH causes various problems within the cardiovascular system including cardiac hypertrophy and abnormalities of left ventricle (LV) function. To evaluate the cardiovascular effects due to GH treatment in idiopathic short stature (ISS), we measured the cardiovascular function. METHODS: Twenty-two echocardiographic studies were performed in ISS who were admitted from Jan. 1994 through Jul. 1996, and they were divided into two groups which revealed in 11 children with GH treatment and in 11 children without GH treatment. RESULTS: The results obtained were as follows, 1) The mean HR in GH group was significantly lower than that of control group (79.9+/-12/min vs. 90.2+/-9/min) (p<0.05), and the mean BP was the GH group 81.6+/-10mmHg and control group 77.7+/-7mmHg. 2) The mean LV isovolumic contraction time (LICT) in GH group was significantly longer than that of control group (35.6+/-3 vs. 32.3+/-2) (p=0.01), but within normal limits. And in GH group, the mean shortening fraction (SF), mean velocity of circumferential fiber shortening (mVcf), and systolic time interval (STI) were 33.9+/-3%, 0.99+/-0.2cir/sec, and 0.15+/-0.04, respectively. In control group, the mean those values were 33.4+/-5%, 0.95+/-0.2cir/sec, and 0.15+/-0.04, respectively. 3) In GH group, the mean isovolumic relaxation time (IRT), peak E velocity (E), peak A velocity (A), and Ea/Aa ratio were 0.05+/-0.01sec, 113.5+/-18cm/sec, 60.5+/-14cm/sec, and 3.9+/-2, respectively. In control group, the mean those values were 0.06+/-0.01sec, 117+/-1.4 cm/sec, 56.8+/-13cm/sec, and 4.7+/-2, respectively. 4) In GH group, the mean cardiac index (CI) and systemic vascular resistance (SVR) were 4304+/-1660ml/min/m2 and 6330+/-764mmHg/ml. In control group, the mean those values were 3835+/-838ml/min/m2 and 6218+/-588mmHg/ml. CONCLUSIONS: These results suggest that the cardiovascular effects did not differ from those in the controls and remained within the normal range after a mean GH treatment duration of 6.2 months.

To our knowledge, MR findings of neuroshistosomiasis has not been reported in Korea. A case of neuroshistosomiasis involving cerebellum and presumably spinal cord is reported. A 40 year old man who had lived in Middle East complained of low back pain and progressive paraparesis for 6 months, and subsequently developed headache, dizziness and diplopia. On cervical spine MRI, there was diffuse enlargement of cervical cord with increased signal intensity on T2 weighted image and nodular heterogenous enhancement after Gd-DTP^ administration. Brain MR imaging obtained 4 months later showed ill-defined, irregularly enhancing heterogenous mass in cerebellar vermis which was proved to be a granulomatous lesion containing shistosomiasis mansoni ova.

Tuberculomas in the spine are estimated to be 15 to 50 times less common than those occurring in the cranium. We experienced a case of intramedullary spinal tuberculoma and brain tuberculoma associated with pulmonary tuberculosis. A 39-year-old male was referred to the National Medical Center via emergency room because of urinary difficulty and lower limb weakness for 3 days. He had been treated with anti-tuberculosis regimens against pulmonary tuberculosis for 20 days. Spinal MRI revealed intradural intramedullary tuberculoma at T5. On the 21st day at the hospital, a generalized seizure attacked him. Brain MRI revealed multiple tuberculoma in both hemispheres, brainstem and cerebellum. He was treated anti-tuberculosis regimens and corticosteroids for 9 months. His condition improved clinically and radiologically. We report this case with a review of the literature.

Luteal phase defect (LPD) is an ovulatory disorder of considerable clinical importance that leads to delayed endometrial maturation and inadequate endometrium for blastocyst implantation. This disorder is implicated in infertility and recurrent spontaneous abortion. We analyzed the endometrial histological maturation, and the estrogen receptor(ER) and progesterone receptor(PR) status in patients with unexplained delayed ovulation, and in patients with ovulation induction by clomiphen citrate. The purpose of this study was to determine whether the length of the follicular phase influences the endometrial histological maturation and the hormonal receptor status, and to know the effect of clomiphen citrate on the endometrium. In the delayed ovulation group, the endometrium was characterized by an irregular outpouching and dilated lumina of the glands, a decreased secretory activity and predecidualization, and a decreased number of granulocytes in the stroma. In the clomiphen citrate-ovulation induction group, glandular proliferation was markedly diminished with poorly convoluted and narrow glands, secretory activity was decreased, stroma was undecidualized, and there was an absence of granulocytes. ER expression was increased in the glandular epithelium in the delayed ovulation group, and both ER and PR expressions were markedly decreased in the glandular epithelium and stromal cells in the ovulation induction group. Endometrial maturation and differentiation may be diminished by increased estrogenic and relatively deficient progesterone effects in patients with delayed ovulation. The hormonal receptor status might also be influenced by hormonal changes. Clomiphen citrate successfully induced ovulation in patients with delayed ovulation, however, endometrial proliferation and maturation were markedly suppressed. This might be related to the lower pregnancy rate and higher abortion rate in patients with clomiphen citrate induced ovulation.

BACKGROUND: Hemoptysis is a common clinical symptom responsible for 11% of admission to the hospital chest service. In KOREA pulmonary tuberculosis is still the most common cause of hemoptysis and the incidence of hemoptysis due to neoplasia has increased. Bronchoscopy and high resonance CT are essential for diagnosis of the cause of hemoptysis. We studied the causes, diagnostic tools and treatment treatment of hemoptysis. METHODS: We conducted a retrospective analysis of clinical profiles, radiologic and bronchoscopy findings and treatments of hemoptysis for 220 patients who were admitted to our hospital with hemoptysis between 1994 and 1998. RESULTS: The mean age at diagnosis was 49.3 years and male to female ratio was 2.1:1. The main causes were active pulmonay pulmonary tuberculosis in 72 cases(32.7%), inactive pulmonary tuberculosis with sequlae in 69 cases(31.4%) lung cancer in 43 cases(19.5%), bronchiectasis in 10 cases(4.5%), and chronicbronchitis in 10 cases(4.5%). The mean amount of hemoptysis for 24hrs was 120cc. The mean duration of bleeding was 25 days. The number of cases with a past history of pulmonary tuberculosis were 128 cases, in which 24 were relapsed tuberculosis cases, 25 chronic tuberculosis cases, 69 inactive tuberculosis cases, and 10 lung cancer cases. High resonance CT was the most useful method for structural etiologic evaluation of hemoptysis developed in patients with inactive tuberculosis, bronchiectasis and aspergilloma. sputum study and bronchofiberscopy were the confirmative diagnostic tools for active pulmonary tuberculosis and lung cancer. The treatments of hemoptysis medical in 152 cases(71.7%), bronchial artery embolization in 39 cases(17.8%), and operation in 9 cases(4.0%). The mean following up duration was 22.4 months. The overall outcomes of hemoptysis were controlled in 77 cases (43.5%), rebleeding in 100 cases (56.5%) and expired in 9 cases (4.0%). The outcomes of hemoptysis in pulmonary tuberculosis were controlled in 21.6%, rebleeding in 78.4%, and expire in 14.7%. CONCLUSION: The most common cause of hemoptysis was related with pulmonary tuberculosis. HRCT was an important diagnostic tool in AFB smear negative active pulmonary tuberculosis and inactive tuberculosis with sequelae. Early, proper management of pulmonary tuberculosis is important for prevention of hemoptysis in Korea.
