The fibrillar coat of Candida albicans is of interest as its significance in antigenicity, antiphagocytosis, and adherence to host tissues. The partial biochemical properties and ultrastructure of fibrillar coat induced by rabbit sera were examined. The induced fibrillar layer was destroyed by treatments of lyticase, proteinase K and dithiothreitol. The total protein concentration of fibrillar cell wall lysate was higher than that of non-fibrillar cell wall lysate, but the total sugar concentration was similar. On SDS-PAGE analysis, the protein profiles between in fibrillar cells and in non-fibrillar cells were shown to be different. In fibrillar cells, the major bands of cell wall lysate were 83, 66, 54, 47, 33, and 26 kDa in dithiothreitol-treated lysate. The proteins of 26 and 19 kDa were predominant in lyticase-treated lysate. Although the fibrillar thickness and protein amount of cell wall lysate were increased in according to the incubation time, the protein profiles did not changed. These results suggest that the proteins of 83, 66, 54, 47, 33, 26, and 19 kDa may be major constituents of fibrillar coat in C. albicans.

The localization and number of oxytocin- and vasopressin-immunoreactive neurons (OXY-IR & VP-IR) and their fibers in the hypothalamic areas (supraoptic nucleus, paraventricular nucleus, lateral hypothalamic area and median eminence) of the hypophysectomized rat were compared with normal rats at 6 months of survival after surgery at the light microscopic level. The number of VP-IR neurons was markedly decreased in the supraoptic nucleus (SON) and paraventricular nucleus (PVN) in the hypophysectomized rats as compared to normal rats. Moreover, The number of VP-IR fibers was decresed in the SON, PVN, lateral hypothalamic area (LHA) and median eminence in the hypophysectomized rats. The number of OXY-IR neurons and thier fibers were also decreased in the SON and PVN in the hypophysectomized rats. The present results demonstrate that hypophysectomy induces a significant decrease in the number of OXY- and VPIR neurons and fibers within hypothalamic areas (SON, PVN, and LHA at 6 months of post-hypophysectomy) are decreased.

A sudden increase in intracranial pressure due to spontaneous subarachnoid hemorrhage or head trauma may result in intraocular hemorrhage. To determine the prognostic implications, the incidence of this after SAH, and 157 consecutive patients with spontaneous subarachnoid hemorrhage were prospectively studied by means of indirect fundoscopy. In 20(12.7%) of these patients, intraocular hemorrhage was seen on initial examination. Mean initial Hunt and Hess and Fisher CT grades were higher in SAH patients with intraocular hemorrhage than in those without(3.57 and 3.57 ; 2.56 and 2.70, respectively, the differences were those without statistically significant. The anatomic distribution of ruptured aneurysm was different in patients with intraocular hemorrhage and thoes without. The overall mortality rate was 19%(26 of 137 patients), but 50%(10 of 20 patients) with intraocular hemorrhage died. Based on the results of the above study we can conclude that in cases of spontaneous subarachnoid hemorrhage, intraocular hemorrhage is not infrequent and that its prognosis is poor.

PURPOSE: Ceftriaxone, a parenteral third-generation cephalosporine, is widely used in the treatment of various bacterial infections. It possesses high calcium-binding affinity, forming complexes with calcium in bile salts to develop precipitate that mimics gallstone on ultrasonography. Biliary pseudolithiasis resolves completely with cessation of therapy, but several symptomatic patients have undergone cholesystectomy. We prospectively evaluated the incidence, risk factors and dose- related comparison with ultrasonography. METHODS: Between November 1998 and August 1999, 81 cases of inpatients on ceftriaxone treatment in Dongguk University Pohang Hospital were enrolled for this study. They were divided according to dose of ceftriaxone, high-dose and low-dose groups. Repeated sonography was performed on 1, 3, 5 and 7 days after initiation of ceftriaxone treatrnent and then weekly until pseudolithiasis were resolved. RESULTS: Thirty-eight percent of the subjects acquired pseudolithiasis. Sonographic abnormalities appeared from 1 to 10 days after ceftriaxone therapy and completely resolved from 1 to 24 days after cessation of ceftriaxone therapy. The incidence of pseudolithiasis was significantly higher in the high-dose group(P<0.001). In the high-dose group, fasting over a day was a significant risk factor of pseudolithiasis(P<0.01). Sex, age, duration of ceftriaxone therapy, laboratory findings, type of infection or chief complaint were not significant risk factors for pseudolithiasis. CONCLUSION: We suggest that abdominal ultrasonography should be considered in all children who receive high dose ceftriaxone with fasting over a day. If pseudolithiasis was developed, we can detect the most of resolution after 30 days of cessation of therapy.

We shoud give attention to Wernicke's encephalopathy as a cause of sudden coma & respiratory arrest in patients, who are not usually suspected to develop the disorder and empirical treatment with thiamine in cases of coma of unknown cause is recommended. Respiratory stimulants, doxapram & aminophylline have an effect in assisting ventilatory weaning in patient with central hypoventilation as a complication of acute Wernicke's encephalopathy No previous reports where doxapram had been used to assist weaning from mechanical ventilation in adults were noted. Nor has newly developed central hypoventilation been identified as an impediment to weaning in literature to date in Korea. We reported a rare case of Wernicke's encephalopathy caused by poor oral intake & inadequate nutritional suppliment after car accident, showing acute coma & respiratory arrest and treated adequately by thiamine replacement & mechanical ventilation with respiratory stimulant.

Steatocystoma multiplex is a rare, inherited disorder that is characterized by multiple, asymptomatic, variably sized dermal cysts. The condition is transmitted in an autosomal dominant fashion; although sporadic cases have been documented. Keratin 17 has been proposed to be an important factor in inherited steatocystoma. In this study, a 29-year old man has a 4-year history of asymptomatic, movable, skin-colored nodules on his face, neck, scalp, anterior chest and back. His father and elder-brother have similar lesions. Histologically, the cysts show a thin stratified squamous epithelium with sebaceous glands arising from its wall and an absence of the granular cell layer. Generally, there are two treatments-medical treatment and surgical treatment. In case of non- inflamed lesions, surgical excision or drainage is regarded as the best treatment. We tried excisional biopsy and until now there has been no recurrence in the operation area over the past 12 months following the operation.

Intramural pregnancy is one of the rarest forms of ectopic pregnancy. The pathologic diagnosis of the intramural ectopic pregnancy requires that the myometrium surrounds the products of conception separated from the endometrial cavity or fallopian tubes. Because the early diagnosis is very difficult, most cases are found after the onset of complications such as a uterine rupture or hemoperitoneum. The previous histories of curettage, cesarean section, myomectomy, salpingectomy and manual removal of the placenta are known as possible etiology of the intramural pregnancy. We have recently experienced a case of intramural pregnancy after 10 times of curettages and are reporting with a brief review of the literatures.

PURPOSE: The most serious complication of suprapubic cystostomy is bowel injury. By computed tomography (CT), we investigated the risk factors of possible bowel interposition through the percutaneous suprapubic cystostomy tract. MATERIALS AND METHODS: From September to October 2009, we consecutively reviewed 795 abdominopelvic CT scans of adult patients performed for various reasons in our hospital. From these scans, we selected the films wherein the urinary bladder was distended more than 6 cm above the symphysis pubis. We then determined whether the bowel was interposed between the bladder and the skin at the routine puncture site of suprapubic cystostomy (the midline of the abdomen 3 cm above the upper margin of the symphysis pubis). We analyzed which factors influenced the possibility of the bowel being interposed between the bladder and the skin at the suprapubic puncture site. RESULTS: A total of 226 CT (148 males, 78 females) scans were selected. The mean patient age was 63 years (range, 26-84 years). The mean distance between the upper margin of the symphysis pubis and the umbilicus was 14.4 cm (range, 7.2-21.0 cm). In the multivariate analysis, obesity, a positive history of radical pelvic surgery, and a short distance (< or =11 cm) between the symphysis pubis and the umbilicus had significant correlations with bowel interposition in the assumed tract. CONCLUSIONS: When performing a suprapubic cystostomy, extreme caution is needed to avoid possible bowel injury in patients who are obese, had a previous radical pelvic operation, or have a short distance between the upper margin of the symphysis pubis and the umbilicus.

The research of p53 is being conducted to find the mechanisms of tumorigenesis and to treat various cancers. Homeodomain-interacting protein kinase2 (HIPK2) is an important factor to regulate p53 and to increase the stability of p53. Activation of HIPK2 leads to the selective phosphorylation of p53, resulting in growth arrest and the enhancement of apoptosis. In this study, the canine HIPK2 cDNA fragments were obtained, and their overlapping regions were aligned to give a total sequence of 3489 bp. The canine HIPK2 cDNA (GenBank accession number; AY800385) shares 93% and 90% sequence identity with those of human and mouse HIPK2, respectively. The canine HIPK2 cDNA contains an open reading frame encoding 1163 amino acid residues and the predicted amino acid sequence has 98% and 96% identity with those of human and mouse, respectively. The deduced amino acid sequence of canine HIPK2 has also all domains' sites compared with human and mouse HIPK2. Therefore, these structural similarities suggested that the canine HIPK2 shares the basic biological functions that HIPK2 exhibit in other species.
