Peutz-Jeghers polyp with pseudoinvasion is characterized by the presence of mucosal islands within muscle layer often associated with mucinous cysts. It occurs when mucosal components completely penetrate the muscularis propria, and shows no cytologic signs of malignancy. In most instances, the lesion may be the result of forces exerted during intussusception in the involved small intestine. We describe a case of Peutz-Jeghers polyposis with pseudoinvasion in a 24-year-old female patient. This patient presented with intussusception and a segmental resection of the ileum was performed. Microscopically, it disclosed a hamartomatous polyp with pseudoinvasion. There were glandular islands and mucinous cysts embedded within the bundle of muscle, layer, extending, to the subserosa. There was o evidence of cellular dysplasia or desmoplasia.

Cyclin Dl, one of Gl cyclin gene subfamily, and human papillomaviruses (HPV) oncoprotein E7 have a homology in binding sites for the retinoblastoma tumor-suppressor protein. In order to evaluate the role of cyclin Dl in human cervical carcinogenesis, the level of its expression was measured and compared to HPV infection. In these studies, 38 normal control cases, 22 carcinoma in situ (CIN) cases, and 16 invasive cervical carcinomas were analyzed by immunocytochemistry and polymerase chain reactions for the detection of expression of cyclin Dl and infection of HPV type 16 and 18, respectively. The cyclin Dl expression was significantly lower in CIN and invasive carcinoma than normal control group regardless of HPV infection (p=0.026). The decreased expression of cyclin Dl in normal control group was not related with HPV infection. However, the levels of expression of cyclin Dl in CIN and invasive carcinoma were correlated with HPV 16and 18 (p 0.026). The expression of cyclin E was not changed in HPV 16 and 18 infected cases. These data provide the evidence that cyclin Dl expression in the lesions of cervical tumor is decreased and it is related with HPU infection.

This study was carried out to demonstrate the mode of ADR-induced cell death(apoptosis) on the light and electron microscopic features, to measure the apoptotic index dependent on various doses of ADR, to investigate the possible mechanism of apoptosis induced by ADR, and to evaluate ISNT method for the detection of DNA strand break. HeLa cells were treated with various doses of ADR 0.1~100.0 microgram/ml and observed under the light and transmission electron microscopes at 6 hours, 1 day and 3 days after ADR treatment. In addition, DNA strand breaks induced by ADR were detected in HeLa cells using the in situ nick translation(ISNT) method. The results were as follows: 1) The cell viability of HeLa cells decreased and the apoptotic index increased following exposure to ADR in a dose-dependent manner, resulting in about 44% of apoptotic index at 100.0 microgram/ml of ADR treatment. 2) Light microscopically, HeLa cells treated with ADR showed shrinkage or condensation of nucleus and cytoplasm. There were various unclear changes showing irregular, large, delineated masses of condensed chromatin abutting on the nuclear envelopes. Later stage of apoptosis revealed contracted and condensed cytoplasm with irregular cell membrane. Electron microscopically, margination of condensed chromatin, dilatation of endoplasmic reticulum under the plasma membrane, aggregation of cytoplasmic organelles with morphologically intact mitochondria, and irregular cell surface with blebbing were observed. 3) ISNT using biotinylated dUTP exhibited strong positive nuclear staining in HeLa cells treated with ADR. There was a marked response at 10.0~20.0 microgram/ml of ADR treatment. It is concluded from the above results that the death of HeLa cells induced by ADR was apoptotic in type based on light and electron microscopic appearance. The apoptotic index correlated with the increasing dose of ADR. ISNT with biotinylated dUTP led to visible evidence of DNA strand breaks following ADR treatment of HeLa cells. ISNT can be used for detection of DNA degradation, caused by activation of endogenous endonuclease, which is an early and specific characteristic of apoptosis.

This study was carried out to investigate the morphologic findings and process of castration-induced apoptosis in the rat prostate. The experimental group was treated with bilateral orchiectomy followed by sequential sacrifices at 1, 2, 3, 4, 5, 6, 7 days and 2, 3 weeks (6 rats, respectively). Ventral prostate was extirpated and examined by light microscopic and immunohistochemical, ultrastructural observation. Apoptotic index increased by 4 days after castration and decreased thereafter. ApopTag stain revealed brownish granular pattern in the nucleus of apoptotic cells. DNA fragmentation rate was 0.5% in the control group and began to increase by 1 day after castration and reached to 11.1% by 4 days and decreased thereafter. PCNA stain showed brownish granular pattern in the nucleus of some epithelial cells of the prostatic glands. PCNA labelling index was 2.4% in the control group and reached peak by 3 days after castration and decreased thereafter. Electron microscopically, there was chromatin condensation with margination toward the nuclear membrane by 1 day after castration. Also noted were condensation of cytoplasm, dilatation of RER and nuclear fragmentation. Apoptotic bodies were formed and phagocytosed by adjacent cells and some apoptotic bodies were found in the lumen of acini. Based on these results, it can be concluded that castration-induced prostatic involution is the result of apoptosis. Detection of DNA fragmentation with ApopTag is a more a accurate method to identify not only apoptotic body formation itself but also the previous step of apoptotic body formation. PCNA labelling index to identify the cellular proliferation seems to play an active role in the early step of apoptosis and be a good tool for investigation of apoptosis.

Authors' presented an interesting case, 19 years old boy, who was been suffered from retinal periphlebitis of both eyes which thought to be induced by Barre Syndrome. This patient also has pulmonary tuberculosis and visual symptoms of Barre Syndrome in this case were ocular pain and visual disturbance that appeared and disappeared suddenly due probably to irritation of the ventral nerve roots (C5 to T1) with also irritation of sympathetic fibers contained in them.

High dose intravenous gammaglobuline (IVLG) therapy is effective in some of the autoimmune diseases. Although the exact mechanism of action of IVIG is uncertain, the action as a neutralizing antibody against unknown etiologic agents, the action of blocking of Fc receptors of effector cells, or the action as a antiidiotypic antibody are suggested. We report a case of 12 year old girl with systemic juvenile rheumatoid arthritis who was treated with high dose IVIG and got a remission. In August 1990 she was admitted to our hospital. because of intermittent fever, transient rash and multiple arthralgia. Under the diagnosis of systemic juvenile rheumatoid arthritis, aspirin (4.0g/day) had been given with symptom improvement. She was readmitted in October 1990 because of aspirin intoxication and acute fulminant hepatitis. She was discharged after recovery and any medicine was not prescribed. In November 1990 she was admitted because of epigastric pain, vomiting, intermittent fever, multiple arthritis, and mild hepatomegaly. Total parenteral alimentation had been given under the diagnosis of superior mesenteric artery syndrome and gold sodium thiomalate (Myochrysine, 5 and 10 mg, two weekly IM injection) was given in conjunction with prednisolone (30 mg/day) and naproxen (375 mg/day). She was admitted again in February 1991 due to the fever, coughing, rash, and hepatosplenomegaly. Pneumonia and leukopenia (2100/mm(3)) were found and gold sodium thiomalate injection was discontinued. Gammaglobulin 1 g/kg/day was given intravenously for 2 consecutive days with dramatic symptom improvement. Five more monthly IV gammaglobulin had been given and the side reaction of injection were nausia, fever, and headache which were controlled by the decrease of infusion rate. Four months after the last IVIG injection she had no symtom of arthritis and the hepatosplenomegaly was decreased. Hemoglobin level was increase to 12.2 mg/dL form 6.2mg/dL and ESR was decrease to 15mm/h. The oral prednisolne and ibuprofen were stopped one year after th last IVIG injection. All the laboratory parameters of arthritis and physical examinations had been normal for more than two year after the stop of all the medications until March of 1994. We suggest that high dose intravenous gammaglobulin can be one of treatments for severe systemic juvenile rheumatoid arthritis.
