Wilms' tumor is one of the most common primary malignant tumors of the kidney during infancy and childhood and is known to be originated from the primitive cells of metanephric blastema. It presents difficulties when encountered in deciding the presence of anaplasia or in differentiating it from other renal tumors of childhood with different biologic behavior because of its diverse histologic patterns and varying degrees of differentiation. Evaluation of clinical and histopathologic features in terms of prognostication was done of 32 cases of Wilms' tumor which were surgically resected and diagnosed in the period from January 1979 through June 1992. Immunohistochemical reaction for cytokeratin, vimentin, actin and desmin was also analysed on all cases of Wilms' tumor in conjunction with clear cell sarcoma of the kidney(CCSK), malignant rhabdoid tumor of the kidney(MRTK) and congenital mesoblastic nephroma(CMN) to assess the validity of immunohistochemistry in differentiating Wilms' tumor from these renal tumors. Twenty four(75%) cases were diagnosed before the age of 5 and 40.7% were under 2 years old. Mixed type was most common(62.5%), followed by epithelial, blastemal and stromal predominant type in descending order of frequency. Anaplasia was observed in 3 cases(9.4%), two of which were epithelial predominant type and one blastemal predominant type. Treatment modality and presence of anaplasia were significantly correlated with 5 year survival rate of patients. Immunohistochemical stain revealed that all epithelial component of Wilms' tumor were positive for cytokeratin and 56.3% of Wilms' tumor had blastemal component which were positive for both cytokeratin and vimentin. Twenty cases(62.5%) of Wilms' tumor had blastemal component which were positive for cytokeratin with a proportion of more than 5% of reactive cells. Stromal component of Wilms' tumor generally did not show differentiation into the specialized type of tissue and all revealed positive reactions for vimentin among which some revealed positive reactions for actin. Only 3 out of 6 cases with rhabdomyoblastic differentiation were positive for desmin. CCSK, MRTK and CMN which have different biologic behavior and treatment modality compared to Wilm's tumor showed positivity only for vimentin and/or actin. In summary, treatment modality and presence of anaplasia are significantly correlated with patients' survival and the immunohistochemical stain for cytokeratin is very helpful in confirming the presence of blastemal component and useful in the differential diagnosis of Wilms' tumor from other kinds of pediatric renal tumors.

Bone remodeling is characterized by the coupling of osteoclast-mediated bone resorption and osteoblast-mediated bone formation. The process is tightly regualted at the local level by an incompletely known netwotk of peptide and non-peptide fators. Nitric oxide(NO), synthesized by nitric oxide synthetase(NOS) from L-arginine, is becoming recognized as an important bioregualtory molecule in a variety of tissue, but little is known about its possible role in periodontal tissue. The purpose of this study is to investigate the expression of nitric oxide synthetase(NOS) in inflamed gingiva and the effects of cytokine on the expression of NOS protein. The expression of NOS in gingival tissue was evaluated by immunohistochemical staining for NOS1, NOS2, NOS3. The effect of cytokine on the expression of NOS in human periodontal ligament cells and osteoblast-like HOS cells by western blot analysis. Further, we studied that NO functions in periodontal ligment cells as a regulatory molecule. PDL cells incubated with NOS inhibitor and donor. The protein expression, type I collagen & non-collagenous protein, nitrate production and cell proliferation were evaluated The results were as follows. 1. NOS1, NOS2, NOS3 was rarely distributed in healthy gingiva, but stronger stained in gingival epithelium, endothelial cells, and mononuclear cells of inflammed gingiva. 2. The cytokine stimulated NOS1, and NOS3 protein were not inducing or inhibitory effect to compared with control in PDL and HOS cells. 3.Incubation of cells with combination of TNF-alpha, IFN-gamma, LPS result in a time dependant increase in NOS2 expression, reaching a maximal level after 24 hours of stimulation. 4. The osteonectin protein inhibitory effect of NMA, inhibitor of NOS, was reversed by Larginine in dose dependant manner. 5. NMA decreased cell proliferation and nitrate production, but the inhibitory efffect of NMA was also prevented by the NO donor, sodium nitropruiside. These results suggest that exogenously synthesized NO was playing a stimulating effect on cell proliferation or on non-collagenous protein expression. Therefore NO have an important role in mediation of localized bone destruction associated inflammatory bone disease such as periodontitis

Since Paget`s first description in 1874 of what is presently known as Paget`s disease of the nipple, similar lesions have been reported rarely on the penis and scrotum, vulva, perineum, axilla and the eyelids. Because it is often associated with a subjacent or visceral malignancy and recurrence, extramammary Paget`s disease(EPD) is considered as malignant condition. This case report describes two patients with extramammary Paget`s disease of the penoscrotal area. One of them had renal cell carcinoma in left kidney and was managed by radical nephrectomy. Treatments for EPD were initiated by CO2 laser 3 or 4 times, but failed and then we excised the lesion widely and closed primarily with split thickness skin graft in one of the cases.

The incidence of synchronous gastric cancer is variously reported to be 2.07%, 5.22%, 6.5%, 8.6%, or 9% and has been increasing recently, probably with advance in the diagnosis of gastric cancer. Our case in presentation is a 70-year-old male patient who had total gastrectomy and esopbagiojunostomy done for synchronous four gastric cancer. Each has different histologic types, Some of these lesions are not suspected before operation and are found almost by chance during histologic examinations after surgery performed only to remove main lesion. So we report this case with a review of literatures.

The effect of Pheniramine(Avil), a histaminergic-1 receptor blocking agent presently employed in treating various allergic diseases on pressor actions of norepinephring(NE) and tyramine (TR) was studied in the rabbit. Pheniramine, when given into a femoral vein with a dose(3mg/kg) enough to block H1-receptor, potentiated markedly the pressor responses of NE and TR. The pressor action of NE augmented by pheniramine was not affected by additional adminstration of debrisoquin (Drenergic neuron blocker) or phenelzine(monoamine oxidase inhibitor) or desipramine(U1-uptake blocker), or while potentiated by additional treatment with chlorisondamine(ganglionic blocker)or reserpine(catecholamine depleter). The hypertensive response of NE to phenelzine or desipramine was reinforced significantly by addition of pheniramine, but the response of NE in rabbits treated with reserpine or chlorisondamine or debrisoquin was not influenced by pheniramine-addition. Elevation of blood pressure to TR potentiated by pheniramine was attenuated significantly by reserpine treatment with chlorisondamine made the significant augmentation of pressor action to TR after pheniramine. Tyramine-induced response of blood pressure after pheniramine, but the response of blood pressure to TR caused by phenelzine or desipramine was enhanced markedly by pheniramine-treatment. From the above experimental results, it is thought that the pressor effect of NE and TR potentiated by pheniramine is similar to that of debrisoquin, i.e. the sensitization of effector cell, and that central action of pheniramine can not ruled out.

We report a premature neonate who suffered from bronchial foreign body. The neonate was delivered at 34 weeks of gestational age, 1,850 g of birth weight, through Cesarean section. After birth the baby showed respiratory distress and received surfactant therapy on the first hospital day. After extubation on the 10th hospital day, the baby experienced 2 episodes of pneumonia in the right upper lung field. On the 27th day after birth, a chest X-ray revealed a feeding tube-shaped foreign body which was located from right main bronchus to trachea, about 4.5 cm long and 2.0 mm wide. The patient was too small to remove the foreign body by even the smallest-diametered fibroptic bronchoscopy. We rotated the baby to a nearly 90 degree head-down position and percussed on the back. After confirming the movement of foreign body in to the trachea, we intubated 3.0 Fr. endotracheal tube under fluoroscopic observation. We found that a tip of foreign body was inserted into the ET tube innerside. We sucked out the foreign body by mechanical suction with central-holed rubber suction tip. Forced expiration with cough reflex and intubation with mechanical suction allowed for the successful removal of the foreign body.

An antisense approach was attempted to investigate the role of antisense GLUT1 RNA in suppressing tumor cell phenotypes using N-ras-transformed NIH 3T3 cells. The established cell line transformed by ras showed typical biological characteristics of cancer cells, such as increased glucose transport, GLUT1 mRNA contents, and the ability to form colonies on the soft agar. In this system, the plasmids (pMAM-GLUT1(rev)) which can transcribe the antisense GLUT1 RNA were transfected and the accompanying changes in the phenotypes of the ras-transformed cells were observed. The expression of antisense GLUT1 RNA by induction with dexamethasone reduced the glucose transport by 30% (1.97 +/- 0.13 nmoles) after 4 min incubation when compared to the non-induction group of transformed cell (2.85 +/- 0.19 nmoles). Also, the number of colonies sized over 50 microns on the soft agar was reduced significantly in the antisense RNA expressing group compared to non-induction group. These results suggest that the expression of antisense GLUT1 RNA reduced the glucose transport and transforming potential in soft agar possibly by hybridization with GLUT1 mRNA in N-ras-transformed NIH 3T3 cells.
