Chorioangioma is the most common primary tumor of the placenta. It is widely accepted to be formed from hamartomatous proliferation of angioblastic cells in early placenta. According to groups who systematically examined the placentas with the greatest scrutiny, the incidence of chorioangioma is 1~1.2% of all placentas examined. The clinical implication of chorioangioma has been emphasized due to its high association with hydramnios, antepartum and postpartum hemorrhage, premature onset of labor, or intrauterine fetal distress or death. The authors experienced a case of a 38-year old multigravida who had undergone 4 consecutive spontaneous abortions. The fifth pregnancy was carried to 35 weeks whereupon a dead fetus was delivered. The placenta was enlarged(950 gm) with multiple protruding nodules into the fetal surface. Microscopically, the nodule was composed of many vilous structures lined by chorionic epithelium. Within these structures was proliferation of endothelial lined capillaries some of which demonstrated ectatic change.

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.

Carcinoma of the uterine cervix is the most common malignant tumor in Korean women. It is well known that carcinogenesis is a multi-step event involoving the inactivation of tumor supressor genes, such as p53 gene and RB gene. The inactivation of the normal functions of the tumor-suppressor proteins pRB and p53 are important steps in human cervical carcinogenesis, either by mutation or from complex formation with the HPV E6 and E7 oncoproteins. The pRB protein regulates early cell cyle progression by controlling transit through the G1 phase of the cell cyle. The p53 tumor suppressor gene product also plays a role in cell cycle control by the transcriptional regulation of cyclin-CDK inhibitor. Cervical carcinoma is an excellent model for studying the stepwise progression of cell transformation because this is reflected morphologically by the increasing dysplasia of the squamous cells before it becomes and invasive squamous cell carcinoma. The aim of this study was to examine the expression of pRB and compared that with overexpression of p53 in a series of cervical lesions including normal tissuess, dysplasias, carcinoma in situ and carcinomas by immunohistochemical staining with monoclonal antibody to elucidate the role of these tumor suppressor genes. The result were as follows: 1. In normal cervical mucosa and CIN I , a few positively stained cells for pRB were seen in basal and parabasal layer. 2. An abnormality of pRB, loss of expression was seen in 23.8% of CIN III and in 10.8% of invasive carcinoma. 3. Overexpression of p53 was demonstrated in 14.3% of CIN III and in 59.5% of invasive carcinoma. 4. The immunoreactivity of p53 was significantly increased (p<0.05) in stage II, III than stage I , whereas downregulation of pRB and tumor stage was not correlated. 5. The immunoreactivity of p53 was significantly increased (p<0.05) in squamous cell carcinoma than in adenocarcinoma, adenosquamous carcinoma and CIN III. These result suggest that an alteration of pRB is more frequently implicated in CIN III than invasive carcinoma, whereas overexpression of p53 may be involevd in late progression of uterine cervical carcinoma.

Herpes simplex esophagitis has been recognized with increased frequency as an opportunistic infection in immunosuppressed or debilitated patients. However, it is also documented as self-limited esophagitis in apparently healthy patients. We report two cases of herpetic esophagitis diagnosed by biopsies. One case was noted in an immunocompetent patient having gastric peptic ulcer who had clinical improvement with symptomatic treatment. And the other was noted in an immunosuppressed patient having chemotherapy for gastric carcinoma who had resolution of symptoms with acyclovir therapy. Histologically, esophageal mucosa exhibited erosion and inflammatory cellular exudate with intranuclear eosinophilic inclusions in the epithelial cells. These were confirmed by the PCR and immunohistochemical stain for herpes simplex virus using a biopsy material.

The purpose of the study is to research the side effects of chemotherapy which are experienced by cancer patients, theirself-care behaviors to manage the side effect symptoms, and to for provide the fundamental knowledge basis for nursing intervention and self-care education. The subjects were 15 cancer patients receiving chemotherapy in 2 university hospitals. The side effects and self-care behaviors were categorized into 7 themes. 1) First theme Patients experienced nausea, vomiting, alteration in appetite, constipation, diarrhea, and indigestion. Patients used emetics, ate sweets, fruits, drank alcohol and cold veberages to deal with nausea and vomiting. They took their favorites, and yogurt and medicine, and an easily digestible diet to decrease the side effects on digestive function. 2) Second theme Patients experienced oral-dryness & stomatitis. Patients consumed water, candy a warm food and various beverages. 3) Third theme, To cope with changed sense of taste, patient ate their favorite foods, and to help offset alteration in tactile sense they used massage. Concerning changed sensitivity to decreased temperature, ultraviolet treatment and various means of keeping warm were used. To deal with the changed sense of smell and hearing, they avoided noise and bad odors as much as possible. 4) Fourth theme Patients experienced discoloured skin and alopecia. Patients wore appropriate clothes to hide it. To deal with alopecia, they used hats, head kerchief, and positive thinking. 5) Fifth theme Patients experienced weight loss, URI symptoms, fatigue, pain, insomnia and they took various food health products, medicines, and naps. 6) Sixth theme Patients experienced musculoskeletal changes and decreased amounts and range of activities. They did self-care behaviors such as taking baths, exercising etc. 7) Seventh theme Patients felt varing level of anxiety and for this they had fellowship with support companies and used religion, self-control, and positive thinking. From the above research, it can be concluded that : Patients used self-care behaviors which were not proved in effectiveness and education for the prevention and management of the related side effects of chemotherapy was not effective, either.

BACKGROUND: The electrophysiological effects of purinergic receptor agonists, adenosine triphosphate(ATP) and adenosine were examined using conventional microelectrode technique in rat atrial muscle fibers under superfused with a normal or a simulated ischemic(hypoxic, hyperkalemic and acidotic) physiologic salt solution(PSS) in vitro. METHODS: Action potential parameters, such as maximal diastolic potential(MDP), action potential amplitude(APA), rate of phase 0 depolarization(dv/dtmax) and action potential duration(APD90) were measured in electrically paced, physiologic salt solution(Tyrode's) superfused left rat atrium. In the experiment of ischemic simulation in vitro, normal physiologic salt solutions(NPSS0 were modified(MPSS) and superfused in substitute for normal Tyrode's solution. To investigate the effects of purinergic receptor agonists, ATP or adenosine was added to the superfused tyrode's solutions(NPSS or MPSS) in molar concentration. RESULTS: Under superfused with normal PSS, ATP(10(-3), 10(-4)M) elicited slight hyperpolarization in MDP, and both ATP(10(-6)-10(-3)M) and adenosine(10(-6)-10(-3)M) shortened the duration of normal action potential in a dose-dependent manner. The other paramaters were not affected by the drugs. Superfusion with ischemic PSS caused reductions in MDP as well as APA, dv/dtmax and, especially, APD90. The effects produced by the initial 10 minutes of superfusion with ischemic PSS almost completely disappeared during a subsequent period of continued superfusion with normal PSS, but, those by the initial 20 min lasted in some degree. Both ATP(10(-4)M) and adenosine(10(-4)M) attenuated the reduction in the rate of phase 0 depolarization and the amplitude of the action potential amplitude produced by the ischemic PSS. CONCLUSION: Purinergic receptor agonists, ATP and adensoine, caused a concentration-dependent shortening of the action potential duration in rat atrial muscle fibers and they attenuated the reductions in the rate of phase 0 depolarization and action potential amplitude in fibers superfused with ischemic PSS.

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.

Since the placenta is an organ composed of blood vessels, it is not surprising that its primary neoplasm would be a vascular tumor. Placental tumors, primary or secondary, have been known to interfere with placental function. Chorioangioma(primary tumor of the placenta), which is the most common of them, occurs with an incidence for clinically significant ranges from 1~2.8:10000 births. These tumors are benign and are not usually associated with clinical sequelae unless they are larger than 5cm in long diameter. About one third of the large chorioangiomas may be associated with the maternal and fetal complications. For diagnosis of these lesions, the ultrasonography was used. If the chorioangioma is suspected, color doppler study is informative to confirm the presence of the vascular channels. We reviewed ultrasonograms and clinical records of seven patients who had been diagnosed as placental chrioangioma. The appropriate diagnostic tests and treatment can then be initiated in order to prolong gestation and decrease fetal mortality and morbidity.
