ABSTRACT
BACKGROUND: This is the studies about "If the soldiers expose in the paraquat, how much have it influenced on themselves who participated in the Vietnam War and their second generation?" and this is also researched about the factors that "How differents do the symptoms according to their health conditions and a class of diseases?". First of all, We divided them into 3 groups as exposure duration and exposure degree of the paraquat and We gave marks against each steps, too. ( point 20: high group). We've focused in "Does the high score really involves with their descendants who suffers from paraquat?" as direct damages men during from June 1965 to February 1971 (72 persons) and their descendants (266 persons) who are in the Pusan veterans hospital and outpatients. METHODS: It is completed by direct interview, telephone interview, army records, army history, and medical records with them. We've tried to minify sample bias as analyzing their information. We could contact only a few people among living in Pusan or Kyongnam province. Generally, someone including persons who couldn't get a damaging proofs from paraquat hardly joined us and the others strongly rejected the interview for this research. RESULTS: Among the 72 participating soldiers in the Vietnam war, average age of patient is 53 years old (the youngest: 46 years old, the oldest: 64 years old), average of exposure score is 16 point (minimum: 1.9 point, maximum: 31.9 point), average of pregnant frequency is 5.2 persons, and average degree of smoking is 14.382 single cigarette (minimum: 4 single cigarette, maximum: 60 single cigarette). The second generation is suffering from abortion, skin disorder, still birth, congenital anomalies, weakness, visual disturbance, peripheral neuropathy in frequency. CONCLUSION: There's no relation between exposure score of paraquat and diseases of the descendants.

Cell-matrix interactions have major effects upon phenotypic features such as gene regulation, cytoskeletal structure, differentiation, and aspects of cell growth control. Upon detachment from the matrix epithelial cells enter into programmed cell death and this cell detachment-induced apoptosis has been referred to as "anoikis". This study was undertaken to determine whether apoptosis is induced by inhibition of contact with extracellular matrix in mouse inner medullary collecting duct cells (mIMCD-3), what are signaling mechanisms of the process and whether EGF protects detachment-induced apoptosis. Upon detachment from the extracellular matrix, MDCK and mIMCD-3, which were derived from inner medulla of SV40 transgenic mouse, entered into programmed cell death as a time-dependent manner. Apoptotic cell death induced by cell detachment increased in serum-free medium, which was partly protected by the addition of epidermal growth factor (EGF). Ly294002 and wortmannin, inhibitors of phosphatidylinositol 3-kinase (PI 3-kinase), negated the EGF effect, whereas PD98059, a MEK inhibitor, did not. The addition of SB203580, an inhibitor of p38 kinase, did not protect apoptosis in suspended mIMCD-3 cells. These results indicate that apoptosis is induced by inhibition of contact with extracellular matrix in mouse inner medullary collecting duct cells and that PI 3-kinase, not MAPK, is a key mediator of the EGF-induced survival of renal epithelial cells in the absence of attachment.

A 69-year-old male was admitted to the neurosurgery department for traumatic intracra-nial hemorrhage in both frontal lobes. After 2 months, he complained of epigastric dis-comfort, nausea, vomiting, and loose stools. The gastric endoscopic examination found acute hemorrhagic gastritis and there were rhabditoid nematode larvae in the gastric fluid and biopsy sections. The filariform larvae of Strongyloides sp. were discovered from a fecal culture. The patient was treated with albendazole (200 mg, po bid, for 4 weeks). The epigastric discomfort disappeared and endoscopic findings improved after treatment.

A 67-year-old male visited Pusan Veterans Hospital due to general weakness and weight loss for 6 months. Physical examination showed non-tender 4 finger breaths sized splenomegaly and both inguinal and cervical lymphadenopathy. The white blood cell count was 25,300/uL with 91% morphologically mature lymphocytes. Bone marrow aspirate revealed hypercellularity with 74.5% lymphocytes morphologically similar to peripheral lymphocytes. The immunophenotpying study of lymphocytes displayed the phenotype of CD19(+), CD20(+), HLA-DR(+), sIg(+) but CD5(-). We concluded that this patients's diagnosis is CD 5 negative B-cell chronic lymphocytic leukemia.
