A congenital salivary gland tumor, sialoblastoma, is extremely rare. A sialoblastoma of the parotid gland, occurring in a 28-week old fetus, is described. The histologic, immunohistochemical, and ultrastructural features of this tumor were studied. The tumor was characterized by solid nests or sheets of tumor cells intermingled with ductal structures lined by a columnar cells. Some of the tumor cells showed squamous differentiation. Immunohistochemically, these epidermoid cells reacted positively with anti-cytokeratin. But anti-S-100, anti- vimentin, anti-smooth muscle actin, anti-GFAP positive cells were not found. The ultrastructure was characterized by primitive epithelial cells. Although various names have been proposed, we favored the term "sialoblastoma". The histogenesis of this tumor is also discussed.

Mullerian Mucinous papillary Cyatadenernas of Borderline tumor(MMBT) is lined by mucinous epithelium of endocervical type and is characterized by papillae architecturally similer to those of serous horderline tumors, It has been described rarely in the literature, Thia case was reported with a brief review of the concerened literatures. It has important clinical and pathological diBerences from mucinous birderline tumors with intestinal differentiation, but has many similatities to mixed epithelial borderline tumora of Mulierian type. Recently, a case of MMBT in a 22 years old woman was experienced at our department. We presented this case with a brief review of literature.

Immunosuppressive therapy based on the use of antilymphocyte globulin (ALG) has become standard therapy for patients with splastic anemia who are not eligible for bone marrow transplantation. In this study, T cell subsets before and after ALG therapy, hematologic responses, complications and prognostic factors were analysed. Eleven (42%) out of twenty-six patients treated with ALG showed response, but two patients showed relapse. Most of the response (9 cases) was noticed within 6 months after the initiation of ALG therapy (median: 3 months). The main complications of ALG therapy were fever (91%), thrombocytopenia (86%), neutropenia (63%), and serum sickness (56%). Four patients were died just ALG therapy because of serum sickness (2 cases), intracranial hemorrhage (1 case), and shock (1 case). Short interval from diagnosis to treatment suggested to show good response (P=0.0575), but it was not significant statistically. Lymphocyte subsets were measured in the blood of 23 patients. Helper T/suppressor T cell ratio (T4/T8 ratio) at the initiation of ALG therapy (day 0) was higher significantly in patients who were responded (P=0.0299). The patients who showed above 1.0 of T4/T8 ratio on day 0 might be speculated good response (P=0.032). More difference of T4/T8 ratio between day 14 after ALG therapy and day 0 might show good response (P=0.0673). Then the actuarial probability of survival at 3 years in patients treated with ALG was 77%. Our data suggest that ALG therapy may be used as an alternative treatment to bone marrow transplantation, and T4/T8 ration of peripheral blood at the initiation of therapy may be used as one of the prognostic factors.

Teratomas of the fallopian tube are extremely rare, and only about 50 cases have reported in the world literature. Most cases of mature cystic tubal teratoma are asymptomatic and are discovered as an incidental finding on physical or radiologic examination, or at the time of laparatomy. We report a case of mature cystic teratoma of the right fallopian tube which was discovered during pelvic ultrasonogram for antenatal care in a 28 year old woman. Right salpingectomy was performed during cesarean section for cephalo-pelvic distortion at IUP 39 weeks. Gross examination of the right fallopian tube reveals a distended fallopian tube, measuring 8cm in length and 2cm in diameter. On section, it is filled with several small pedunculated nodules and cysts containing sebaceous materials. Microscopically the tumor was seen in continuity with the lining epithelium of mucosal folds. The majority of the tumor was composed of well differentiated mature elements of three germ layers with skin and skin appendages, mature brain tissue, bone, breast tissue, intestinal mucosa and bronchial epithelium.

This is a report of clinical study on the 63 patients of symptomatic urinary tract infection who were hospitalized at the Department of Pediatrics in Kangnam General Hospital during the period between the May of 1989 and the September of 1992. The observation results were as follows: 1) The frequency of urinary tract infection (UTI) was the highest in children under the age of one year (66.7%). 35 patients were male, while the other 28 were female. The ratio of male and female patients was 1.25:1. 2) Fever was observed in most of the cases. Systemic nonspecific manifestation was predominant in the infancy and early childhood, whereas local symptom of UTI was predominant in the late childhood. Among the 35 male patients, 32 cases were phimoses. As for the other 3 cases, Phimoses were not identified. 3) E. coli had the most frequency (65.3%), followed by Klebsiella, Enterobacter, Pseudomonas in descending order. 4) In the vitro antimicrobial susceptibility test, Gram negative organisms such as E. coli Klebsiella, Enterobacter were sensitive to cefotaxime, amikacin, and ampicillin/sulbactam. Meanwhile, Gram positive organisms such as Staphylococcus, Enterococcus were sensitive to vancomycin and cephradine. 5) The renal ultrasonography test was performed for 59 patients, 13 cases of whom showed abnormal findings. 6 cases out of the 13 abnormal patients had hydronephrosis. 6) DMSA renal scan was performed for 40 patients within 2 months of an acute pyelonephritic attack. Signs of pyelonephritic change were found in 18 patients. DMSA scan was repeated 4~12 months later in 4 of these patients. This showed renal cortical scarring in all patients. 7) Voiding cystourethrographic findings in 38 patients showed vesicoureteral reflux in 13 patients. 8) We performed urine culture again after 48 hours from the beginning of therapy and 85.5% of the cases became sterile. 9) The recurrent percentage of UTI was 23.8% with the ratio of 1:1.5 between male and female. Most of the patients were clildren under the age of one year. 10) Operations were made on two cases showing the increase of reflux during the follow-up of unilateral Grade ll and Grade 3 reflux, respectively. Operations were also performed on other two cases with bilateral Grade IV reflux. All the cases were good after the operations. In the meantime, as for another two cases having the right reflux of Grade lland the bilateral reflux of Grade lll, the refluxes were able to be reduced by prophylaxis only, in the course of following up.

Cyclins are proteins that activate different cyclin-dependent kinases(CDKs) and promote the cell cycles. Their correlations with several human cancers have been identified. Cyclin E, as one of G1 cylins, produces DNA replication through the progression of cell cycle G1 --> S phase. In contrast, cyclin-dependent kinase inhibitors(CDKI) bound with cyclin E-cdk2 complex control the cell cycle and inhibit the cell proliferation. P21(WAF1) proteins, which are CDKIs, are transcripted by a p53 gene and participate in the cell cycle inhibition. Variant p53 proteins produced by a mutated p53 gene lose the ability to control of the cell cycle resulting in cell proliferation. This study is aimed to reveal the expressions of cyclin E, p21(WAF1) protein, p53 variant protein in colorectal adenomas and carcinomas, and also reveal their correlations in the process of carcinogenesis. Twenty-one colorectal adenomas or adenomatous polyps, and thirty colorectal carcinoma tissues were obtained by operative resections or endoscopic polypectomies. Immuno histochemical stains of the above-mentioned three proteins and a statistical analysis of their correlations were made. The results were as follows: 1. P21 proteins were expressed in the upper-one third layer of all normal colonic mucosa, but cyclin E and variant p53 protein were not identified. 2. Cyclin E was expressed in 23.8% of adenomas and 76.7% of carcinomas. Variant p53 protein was expressed in 71.4% of adenomas and 83.3% in carcinomas. The degree of positivity of variant p53 expression was correlated with cancer staging. P21 protein was expressed in all adenomas, similar to normal mucosa, but was not expressed in 43.3% of carcinomas. 3. Expression of cyclin E was increased as to the positivity of variant p53 proteins but the correlations of p21 proteins and cyclin E, and p21 proteins and variant p53 proteins were not identified. Cancer staging was not correlated with the expressions of the three proteins. In conclusion, it can be thought that the overexpression of cyclin E and variant p53 proteins, and the loss of p21 proteins are related with the colorectal carcinogenesis. We can also identify the relationship of cyclin E and variant p53 proteins.
