While studying Bombyx mori "Zipnuae" inoculated with an entomopathogenic fungus, Paecilomyces tenuipes, a mycoparasitic hymenoascomycete with a long neck was isolated from the silkworm rearing room. The fungus was identified as Syspastospora parasitica which has been recognized as a hyperparasite on various moniliaceous hyphomycetes. A descriptive illustration is presented in this study.

We present an autopsy case of signet ring cell carcinoma of urinary bladder which underwent widespread metastsis through nearly entire organ. The patient, 45-year old male, suffered from hematuria, dysuria and flank pain for 6 months. Under the diagnosis of the signet ring cell carcinoma by the cystoscopic biopsy, radical cystectomy and ileocutaneous ureteral division were performed. But he died after 11-months after the diagnosis. The autopsy confirmed the widespread metastasis at the lung, kidney, adrenal gland, parathyroid gland, heart, stomach, ileum, spine, rib and meninges. The preveously resected urinary bladder discolosed the well defined fungating mass at the dome and anterio-lateral portion without apparent evidence of the remnant of the urachus. Histologically, the signet ring cells were predominent and focally mucinous pool floating the signet ring cells was noted. We could find several foci of the well differentiated adenocarcinoma and poorly differentiated adenocarcinomas. The above findings may reflect that the origin of carcinoma may be from the multipotential transitional cell epithelium.

Osteoblastoma is a rare benign bone tumor and is characterized hitologically by an abundant number of osteoblasts and by the presence of s large amount of osteoid tissue in a highly vascular matrix. The lesion is frequently encountered in children and adolescents with most of the cases occuring between the ages of 10 and 25 years. There is significant sex prevalence (M.: F.=2: 1). Up to now there has been few reports of a benign osteoblastoma occuring in the cervical spine. This report describes a boy of a benign osteoblastoma which involved the cervical vertebral arch and spinous process, presenting with pain and limitation of motion. He was given en-bloc resection of tumor mass and confirmed by histological examination. Postoperation result was good and he goes school without any problem in about 12 months of follow up.

Repeat cesarean section is one of the leading causes to make increasing a rate of cesarean section. Trial of labor TOL after cesarean section is attempt to reduce the rate of repeat cesarean section. Trial of labor has been well established as a safe alternative in carefully selected women with transverse scars in the lower uterine segment. This study was based on 104 cases of delivery with prior cesarean birth at the Chonbuk National University Hospital from January, 1991 to June, 1997. The results were as follows: 1) Among 1400 cases with previous cesarean delivery, trial of labor was done in 104 cases (7.4%). Among 104 cases, vaginal birth was successfully completed in 96 cases (92.3%). 2) Among 28 cases with PGE2, vaginal tablet, vaginal delivery was done in 23 cases (82.1%). 3) Among 22 cases with more than 4 of Bishop score, vaginal delivery was done in 21 cases (95.5%), and among 6 cases with less than 3 of Bishop score, vaginal delivery was done only 2 cases (33.3%). 4) There was no matemal death or uterine rupture in the cases of trial of labor, But in 2 cases, uterine dehiscence was observed in 4 cases and postpartal bleeding (more than 400ml) was developed. 5) In the cases of cesarean section, mean of hospital day was 7 days and medical fee was about 400,000 won. In the cases of vaginal birth after cesarean section, mean of hospital day was 2.6 days and medical fee was about 100,000 won. In condusion, vaginal birth after cesarean section is safe and effective alternative to elective repeat cesarean section and also the use of PGE, vaginal tablet is so effective to increase success rate of vaginal delivery. After all, positive these trials might decrease cesarean rate and increase maternal health and quality of medical care.

Systemic lupus erythematosus(SLE) is a multisystem disorder with a peak age of onset in the second and fourth decades of life predominantly occuring in females who will usually have the potential to become pregnant. This female to male predominance is greatest during childbearing years approaching a ratio of 13:1, after the menopause it declines to a ratio of 3:1, the ratio also seen in prepubertal years. In practice, despite the higher prevalence of rheumatiod arthritis, pregnancy in SLE is the most common management problem confronting physician and obstetrician amongst the connective tissue disorders and it is particularly important as the outcome of pregnancy is more unpredictable in this disease. As well as having clinical consequences for the health of both mother and fetus, pregnancy in lupus provides a model for studying the importance of other biological phenomena characterizing the disease. For example, the transplacental passage of maternal antibodies to Ro(SSA) and La(SSB) and their strong association with the neonatal lupus syndrome suggests a pathogenetic role for these autoantibodies. Other relevant issues are feto-meternal immunological tolerance and hormonal interaction with the immune system. We have experienced a case of recurrent pregnancy loss associated with systemic lupus erythematosus. So we report this case with a brief review of literatures.

PURPOSE: Paranasal sinusitis, easily overlooked owing to it's benign symptomatology, should be considered when the upper respiratory tract infction persists longer than seven days. Without early recognition and appropriate management, the disease will take a chronic course and the incidence of complications will be increased. The significance of paranasal sinusitis among Korean children has not appropriately been appreciated; therefore, a clinical study was under-taken to help understand clinical characteristics of paranasal sinusitis in Korean children. METHODS: One hundred sixty five(34.3%), out of 481 patients with no underlying disease seen at the outpatient division of the department of pediatrics, Hanyang university hospital from April 1992 to August 1993, were diagnosed of maxillary sinusitis and included in the study to investigate age and sex distributions, clinical manifestations, radiographic findings, and response to antibiotics therapy. Five patients followed up for less thant two weeks and 45 patients lost in follow up within 3 weeks were excluded in the evaluation of therapeutic response, which were done on the basis of clinical and radiographical analysis. RESULTS: 1) Maxillary sinusitis occurred frequently in young children; among 165 patients, 129 patients(78.3%) were wunder 5 years of age, with 83 patients(50.4%) younger than 3 years of age. The male to female ratio was 1.4:1. 2) One hundred twently three patients(74.5%) had acute sinusitis, 39 patients(23.7%) subacute sinusitis, and 3 patients(1.8%) chronic sinusitis. The most common clinical symptom was cough in 124 patients(75.2%), followed by nasal discharge in 103 patients(62.4%), nasal obstruction in 76 patients(46.1%), and fever in 49 patients(29.7%). The physical finding most commonly observed was postnasal drip in 35 patients(21.2%), followed by otitis media in 21 patients(12.7%), and throat injection in 19 patients(11.5%); however, physical examination was not contributory in 77 patients(46.7%). 3) Radiographic findings on Water's view illustrated opacification in 98 patients(59.4%), mucoperiosteal thickening in 82 patients(49.7%), and air-fluid level in 4 patients(2.4%). Bi-lateral radiographic involvement was 4 times more common than unilateral one. 4) The patients with maxillary sinusitis were trated with amoxicillin(AMX), trimethoprim-sulfamethoxazole(TMP-SMZ)+/-erythromycin(EM), amoxicillin-clavulanate(AMX-CLV) or cefaclor(CCL) in sequence depending on the therapeutic response to each antibiotics. The therapeutic outcome with each antibiotics was 16.3%(15/92) with AMX, 56.7%(51/90) with TMP-SMZ, 70.6%(24/34) with AMX-CLV or CCL. Among 115 patients who have been followed up longer than 3 weeks , 90 patients(78.3%) improved clinically and/or radiographically. Among 90 patients with improvement, 32 patients(35.5%) showed clinical and/or radiographical responses in less than 3 weeks of treatment with effective antibiotics, however 19 patients(21.2%) needed to be treated for longer than 7 weeks. CONCLUSIONS: The data indicated that paranasal sinusitis is a common disease among Korean children, especially in very young ones. Once antibiotic therapy had begun, the follow-up were not infrequently interrupted. The therapeutic response to antibiotics, recommended currently for therapy of paranasal sinusitis, were not good.

Toxoplasma gondii, an intracellular coccidian protozoan, is the causative agent of toxoplasmosis, a widespread infection affecting various birds and mammals including humans. In immunocompetent hosts, the infection is usually asymptomatic and benign. Toxoplasmosis is either congenital or acquired. In general prenatal therapy of congenital toxoplasmosis is beneficial in reducing the ncy of infant infection. Therapies are based primarily on spiramycin because of the relative lack of toxicity and high concentration achieved in the placenta. Clindamycin is the standard drug for chemoprophylaxis in newborn infants, and is directed at preventing the occurrence of retinochoroiditis as a late sequel to congenital infection. The standard treatment for acquired toxoplasmosis in both immunocompetent and immunodeficient patients is the synergistic combination of pyrimethamine and sulphonamides. Toxoplasmic encephalitis is tbe most common manifestation of acquired toxoplasmosis in immunocompromised patients and if not treated is fatal. However, because of toxicity, the therapeutic efficacy of pyrimethamine sulphonamide combinations may be seriously limited in immunodeficient patients. We have experienced a case of toxoplasmosis during the workup of habitual aborter. So we report this case with a brief review of literatures.
