Prolactin is elevated in the serum of patients with cervical carcimomas. It is suggested that such edtopically secreteted prolactin may be a potential marker for detecting early occult tumors or gauging the effectiveness of therapy for human cervicla carcinoma. We have immunohistochemical study to investigate the presence or absence of prolactin in 16 cases of nrmal cervical tissues and 26 cases of neoplastic formalin fixed cervical tissues. The results were as follows. 1. All cases of 10 normal uterine cervical tissues and all cases of 5 squamous metaplasia of the cervix revealed positive reaction to prolactin antisera. 2. One case of four moderate dyplasia of the cervix revealed positive reacion to prolactin antisera. 3. One case of five squamous cell carcinoma in situof the cervix revealed positive reaction to prolactin antisera. 4. All cases of 10 keratinizing sqyamous cell carcinoma of the cervix revealed positive reaction to prolactin antisera, but only 1 case non-keratinizing sqyamous cell carcinoma of the cervix revealed positive reaction to prolactin antisera. The results are suggested that prolactin may play a some role in the developement and growth of the cervical carcinoma. But further stydy of the biologic actions of prolactin in many cervical tissues is warranted.

Natural Killer (NK) cells are a subpopulation of in vivo activated lymphocytes that display spontaneous cytotoxicity against a variety of targets as virus-infeeted, and transformed neoplastic cells, in major histocompatibility-unrestricted fashion. Depression of the NK aetivity in patients with advanced stages of various types of solid neopls,sms appears to be dependent upon the prcgressive growth and metastatic spread of the tumor. There are many reports that different distribution of subpopulations of lymphocytes in neopiastic tissue may influence the prognosis of the patients, In this study, we have performed immunohistochemieal study with Leu-7, MT1, LN2, and antilysozyrne antiserum on the tissue of uterine cervieal dysplasia and cancer to investigate the distribution of the NK cell, T cell, B cell, and macrophage. The results were as follows ; 1. The major subpopulation of lymphocytes infiltrating the lesion of intraepithelial neoplasia and squamous cell carcinama was T cell. 2. The number of infiltrated. lymphocytes was layer in the lesion of keratinzing type than in that of non keratinizing and small cell earcinorna of the uterine cervix. 3. NK cell was more frequently noted in the malignant lesion than the dysplastic lesion.

The induction of interleukin-6 (IL-6) using combined proinflammatory agents (LPS/IFN-gamma or TNF-alpha/IFN-gamma) was studied in relation to p38 mitogen-activated protein kinase (MAPK) and NF-kappaB transcriptional factor in primary neonatal cardiomyocytes. When added to cultures of cardiomyocytes, the combined agents (LPS/IFN-gamma or TNF-alpha/IFN-gamma) had stimulatory effect on the production of IL-6 and the elevation was significantly reduced by SB203580, a specific p38 MAPK inhibitor. SB203580 inhibited protein production and gene expression of IL-6 in a concentration-dependent manner. In this study, IFN-gamma enhancement of TNF-alpha-induced NF-kappaB binding affinity as well as p38 MAP kinase activation was observed. However, a specific inhibitor of p38 MAPK, SB203580, had no effect on TNF-alpha/IFN-gamma or LPS/IFN-gamma-induced NF-kappaB activation. This study strongly suggests that these pathways about TNF-alpha/IFN-gamma or LPS/IFN-gamma-activated IL-6 release can be primarily dissociated in primary neonatal cardiomyocytes.

BACKGROUND: Paraquat is a bipyridyl compound, and when ingested, concentrated paraquat can cause either rapid death from multisystem failure and cardiovascular shock or delayed death from progressive pulmonary fibrosis. Paraquat is poorly absorbed by inhalation, but when ingested orally, severe illness can occur. Death usually occurs within 2 days if more than 50mg/kg of paraquat is ingested. The most important prognostic indicator is the quantity of paraquat absorbed, as shown by the plasma paraquat concentration. However, in Korea, there are few, if any, institutes that can measure the plasma paraquat concentration, and the prognostic indication depends mostly on the description given by the patients and their families about the amount of paraquat ingested, which is often underestimated or overestimated. For these reasons, we tried to compare the plasma paraquat concentrations with amount of paraquat described by patients or their families. METHODS: We reviewed the medical records of 59 patients with acute paraquat poisoning from February 1998 through February 1999. The paraquat concentrations in plasma were measured at Presbyterian Medical Center by using high performance liquid chromatography. RESULTS: There was a striking discrepancy between the plasma paraquat concentration and the ingested amount described by the patients or their families. CONCLUSION: We recommend that the plasma paraquat concentration be measured in patients being treated for acute paraquat poisoning.

OBJECTIVES: Apoptosis may play a major role in determining the growth and progression of the tumors. Certain oncogenes and tumor supressor genes are known to modulate apoptosis. The aim of study was to investigate whether apoptosis is related to the degree of differentiation, MIB-1 indicies, and expression of mutated p53 and bcl-2 in cervical neoplasms. MATERIALS AND METHODS: We examined 57 samples of normal, premalignant(i.e. mild, moderate and severe dysplasia and carcinoma in situ), malignant cervical tissue to evaluate whether differences in the apoptotic activity. Apoptotic cells and bodies were visualized by 3' end labelling. Simultaneously, quantitative immunostaining was performed for bcl-2 and p53, two known regulators of apoptosis. RESULTS: The cell proliferation index as determined by MIB-1 immunohistochemistry increased with progression from normal to cervical intraepithelial neoplasm and invasive cancer. The apoptotic index(AI) also increased with grade of lesion and was significantly associated with cell proliferation. However, the extent of apoptosis did not correlate with the expression of p53 and bcl-2. CONCLUSIONS: These results suggest that the elevation of AI in cervical neoplasm is associated with cell proliferation activity but is independent of the expression of p53 and bcl-2. It is likely that the effects on apoptosis of bcl-2 and p53 are countered by those of other oncogene products and/or additional factors that regulate apoptosis in vivo.

Phacoemulsification of cataracts with small pupils would induce serious complications in some instance, but we could perform phacoemulsification and IOL implantation in the posterior chamber without any serious complications.We did not need any iris retractors or adjacent iris surgery.Thirty-one eyes of 28 patients with a pupil diameter equal to or less than 4 mm at the beginning of the procedure were reviewed.We analyzed them in the preoperative ocular problems, the size of pupil and the method of enlargement, the technique of nucleus removal, complications, and vision after six months follow-up.Preoperative pupillary diameter was less than 3 mm in 26 cases (83.9%), the most frequent preoperative ocular problem was uveitis with 19 eyes (61.36%).Removing pupillary membrane, releasing of synechiae and mechanical pupillary stretch followed by viscoelastic injection were effective in pupillary expansion.Central phaco chop technique was effective in small pupil cases.In complications, focal corneal edema in 7 eyes and mild iris damage in 6 eyes during surgery.Postoperatively, fibrinous reaction developed in 8 eyes.Postoperative corrected vision of 0.5 or better was in 15 eyes (48.4%), and 22 eyes (71%)had visual increment by 2 lines or more in the Hann's vision chart.In conclusion, phacoemulsification of cataracts with small pupils could be performed safely without serious complications, even with no iris retractor or iris surgery).

Because nonspecific colonic ulcer is an unusual condition and varies markedly in clinical presentation and course, preoperative clinical diagnosis of nonspecific colonic ulcer is very difficult, But now, preoperative clinical diagnosis can he made by advent of colonofiberscopy. And, it is very important to diagnose this disease early, because late diagnosis make a poor prognosis. We report a case of nonspecific colonic ulcer diagnosed by repeated colonofiberscopy and treated with surgery.
