PURPOSE: To determine the long-term follow-up CT findings of paraquat-induced lung injury. MATERIALS AND METHODS: Six patients who ingested paraquat underwent sequential follow-up CT scanning during a period of at least six months, and the results were analysed. Scans were obtained 1-6 (mean, 3.3) time during a 7-84 (mean, 25.7) months period, and the findings at 1-2 months, 3-12 months, 1-2 years, 2-3 years, and more than above 7 years after poisoning were analyzed. RESULTS: We observed irregular-shaped areas of consolidation with traction bronchiectasis at 1-2 months (5/5), irregular-shaped consolidation and ground-glass opacity (5/5) at 3-12 months, and irregular-shaped consolidations/ ground-glass opacity (4/5) and focal honeycombing (1/5) one year later. In the same patients, follow-up CT scans showed that some areas of focal consolidation could not be visualized and the radio-opacity of the lesions had decreased. CONCLUSION: The HRCT findings of paraquat-induced lung injury were irregular shaped areas of consolidation 1-2 months after ingestion, and irregular-shaped consolidation and ground-glass opacity or focal honeycombing 3-12 months later. At this thim slight improvement was observed.

Meigs' syndrome is defined as a hydrothorax with ascites and a pelvic tumor, both of which resolve on removal of the tumor. Pseudo-Meigs' syndrome is a variant not possessing the original tumor cell types described by Meigs. Both these syndromes should be considered in otherwise healthy women who present with either new or recurrent hydrothorax and ascites. Pseudo-Meigs' syndrome occurs with the clinical triad of (1)ascites, (2)pleural effusion and (3)Brenner tumors, struma ovarii, benign thecomas, extreme ovarian edema, uterine leiomyomas or other benign pelvic tumors. A case of Pseudo-Meigs' syndrome associated with Brenner tumor is presented with a brief review of literatures.

The purpose of this study is to verify severity of asthma in asthmatic patients through through the arterial blood gas analysis. Subjects were consisted of 103 patients (74 boys and 29 girls), between 2~13 years of ages. Clinically, asthmatic patients were classified into 6 groups, i, e., group 0(no rhonchi), group 1(rhonchi only), group 2(mild attack), group 3(moderate attack), group 4(severe attack), group 5(respiratory failure with disturbance of consciousness). PH kept normal range in the group 0, group 1, group 1 and group 3,but began decrease in the group 4.There was linear fall in Po2 and began decrease in the group 3. HCO3- maintained normal level through the whole range. BE showed acidemia on the whole, and began distinctive decrease in the group 4 and group 5, especially. Hypoxemia, hypercapnia and acidemia were common in patients in severe attacks with disturbance of consciousness.

Neuroendocrine tumor (NET) is a cancer-like tumor that occurs mostly in the gastrointestinal system. Within the gastrointestinal tract, NET most commonly occurs in the rectum whereas appendix is very rarely involved. In most cases of appendiceal NET, it is found at a relatively early stage compared to other NETs because appendiceal NET frequently presents with acute appendicitis because appendiceal NET frequently presents with acute appendicitis even when the size is smaller than 1 cm. Therefore, it is very rare for lymph node metastasis to occur in a young adult. Herein, we report a rare case of grade 1 appendiceal NET with lymph node metastasis which developed in a teenage male.

A healthy 12-year-old girl had noted over 2 years a gradual-growing painless nodule on the area below the right axilla. The lesion measuring approxima:;ely 1.2 x 1.2 x 0.4cm in size, had a reddish-blue colored ulcerative papule raised on its cente with mucous discharge to compression. Histopathelogically, a circumscribed solid tumor located in the deep dermis, revealed the predominnntly epidermoid features of polyhedral cells, with the mucous cells within and at the peripiiery of the tumor. The mucous cells exhibited diastase-resistant PAS -positive, alcian-blue reactive at pH 2.5 and mucicarmine-positive reactions. Results of irnmunoperoxidase staining for cytokeratin and carcinoernbryonic antigen were focally cytoplasmic-positive, while negative for S-100 protein and epithlial membrane antigen. She has remained free of disease one year following excision.

GABA is an inhibitory neurotransmitter in central nervous system and produce sedative, antianxiety and muscle relaxing effects via GABA(A) receptor or GABA(B) receptor. Recently it is known that GABA is widely distributed throughout peripheral organs and may play a physiological role in certain organ. The vas deferens is innervated by species-difference. These study, therefore, was performed to investigate the mode and the mechanism of action of GABA on the norepinephrine-, ATP- and electric stimulation-induced contraction of vas deferens of rat. Sprague-Dawley rats were sacrificed by cervical dislocation. The smooth muscle strips were isolated from the prostatic portion and were mounted in the isolated muscle bath. PSS in the bath was aerated with 95/5%-O₂/CO₂ at 33℃. Muscle tensions were measured by isometric tension transducer and were recorded by biological recording system. 1. GABA, muscimol, a GABA(A) agonist, and baclofen, a GABA(B) agonist inhibited the electric field stimulation (EFS, 0.2Hz, 1mSec, 80V, monophasic square wave)-induced contraction with a rank order of potency of GABA greater than baclofen greater than muscimol. 2. The inhibitory effect of GABA was antagonized by delta aminovaleric acid (DAVA), a GABA(B) antagonist, but not by bicuculline, a GABA(A) intagonist. 3. The inhibitory effect of baclofen was antagonized by DAVA, but the effect of muscimol was not antagonized by bicuculline. 4. Exogenous norepinephrine (NE) and ATP contracted muscle strip concentration dependently, but the effect of acetylcholine was negligible and GABA did not affect the NE-and ATP-induced contractions. 5. GABA, baclofen and muscimol did not affect basal tone, and GABA did not affect the NE-and ATP-induced contractions. 6. EFS-induced contraction was inclucling 2 distinctable components. The first phasic component was inhibited by beta gamma-methylene ATP (mATP), a desensitizing agent of APT receptor and the second tonic component was reduced by pretreatment of reserpine (3 mg/Kg, IP). 7. GABA inhibited the EFS-induced contraction of reserpinized strips, but not the mATP-treated strips. These results suggest that in the prostatic portion of the rat vas deferens, adrenergic and purinergic neurotransmissions are exist, and GABA inhibits the release of ATP via presynaptic GABA(B) receptor on the excitatory neurons.

An appendiceal mucocele (AM) is a rare tumorous condition of the appendix. Many patients with AM are admitted to the hospital with abdominal pain or discomfort, and many cases are found incidentally. Although the rate of complications in patients with AM is very low, if left untreated, a mucocele may rupture and produce a potentially fatal entity known as pseudomyxoma peritonei. In this paper, we report a case of an 80-year-old man with necrotizing fasciitis arising from an enterocutaneous fistula caused by AM.
