Normal C3WHeN strain mice exposed to topical 8inethoxypsomlen plus long wave ultraviolet (PUVA) showed a reduction in contact hypersensitivity, (CH) which was localized to the skin in the area of PUVA treatment (local suppression), whereas systemic PUVA treatment caused diffuse suppression of CH reaction, regardless of the application site of 2,4-dinitro-1-fluorobenzene (DNFB). There seem to be two different mechanisms responsible for CH reduction by PUVA. Local suppression by topical PUVA treatment was thought to be a result of blocking the afferent phase of immune response, it was associated with a lack of CH effector cells in the peripheral lymph nodes and could not be reversed by indomethacin treatment. Diffuse suppression induced by systemic PUVA treatment seemed to be associated with blocking of egress of effector cells from the regional lymph nodes, this depressed CH response was prevented when indomethacin was administered before PUVA treatment.

Routine chest radiography in a 21-year-old man revealed the presence of an asymptomatic mass at the right lower lung field. Chest radiographs showed multiple cysts with air-fluid level and air-meniscus within the consolidation at the right lower lung field. Chest CT scans demonstrated a non-enhancing solid mass, with air-meniscus, within a thin walled cavity, and multiple cysts with fluid or air-fluid level at the posterior portion of the right lower lobe. An abnormal artery was seen at the level of the 12th thoracic vertebra. Thoracic aortography revealed a feeding artery arising from the descending thoracic aorta and supplying the parenchymal lesion. We report the typical radiologic findings of intralobar pulmonary sequestration with aspergilloma, a condition confirmed by surgery and the pathologic findings.

We have investigated the changes of DNA ploidy and S-phase fraction in proliferative lesions of rat liver. Proliferative lesions were induced by diethylnitrosamine and partial hepatectomy. DNA ploidy was measured by flow cytometer, and S-phase fraction was measured by in situ bromodeoxyuridine(BRdU)-anti BRdU monoclonal antibody techniques. Normal liver and initiated lesion revealed DNA diploidy or DNA tetraploidy. Hepatocyte nodule (NODULE) and hepatocelular carcinoma (HCC) revealed DNA diploidy, tetraploidy or aneuploidy. S-phase fraction was 1.0+/-0.9, 1.0+/-0.9m 3.7+/-2.3, 5.5+/-4.9, and 13.8+/-11.6 in normal liver, initiated lesion, NODULE not associated with HCC, NODULE associated with HCC, and HCC, respectively. In NODULE associated with HCC, it was widely distributed, ranging from 0.8 to 15.5%. In conclusion, S-phase fraction appeared to be increased as the hepatocarcinogenesis proceeded, but DNA ploidy did not. There was a heterogeneity of DNA ploidy and S-phase fraction in the proliferative hepatic lesions.

Invasive lobular carcinoma (ILC) is the second most common kind of breast cancer. Diffusion weighted imaging (DWI) and positron emission tomography/computed tomography (PET/CT) are functional modalities for presenting the biological characteristics of breast cancer. The purpose of this article is to study the relationship between DWI or PET/CT and ILC's prognostic factors. The relationship between the apparent diffusion coefficient (ADC) values, standard uptake value (SUV)max and prognostic factors of ILC were statistically evaluated. The ADC values were lower in mass types of ILC. SUVmax was statistically higher in grade 3 and 4 background parenchymal enhancement and positive lymph node metastasis. ADC values of DWI and SUVmax of PET/CT can be helpful in the prediction of the prognosis of ILC.

Isolate fracture of lunate is very rare. The authors reported a neglected fracture of lunate which was founded incidentally after the dorsal wall fracture of triquetrum. Pain reduction and improvement of range of motion was achieved after excising the dorsal fragment of lunate.

PURPOSE: Recently, the emergency medical information center has evolved into a new alternative institution providing emergency medical dispatching in Korea. The objective of this study is to analyze the recognition level of the emergency medical information center, the compliance of the emergency medical dispatch, and the accuracy of dispatching questions for appropriate triage. METHOD: A telephone survey of Gwangju citizens and a retrospective analysis of audio recordings of dispatcher-caller conversations collected by the Gwangju Emergency Medical Information Center for one year were conducted. RESULT: Of 105 respondents, only 21 (21.9%) were aware of the existence of the emergency medical information center and it's telephone number '1339' while 92 (87.6%) respondents were aware of 119, another emergency call number for ambulance service. Distributions of calls are as follows: The most frequent age was 0~9 (43.1%) years and the busiest hour was between 18:00 and 23:59. Also, most callers asked about abdominal pain (19.7%), high fever (10.9%), and injury (10.5%). The compliance of callers to dispatcher's recommendation, 'reassurance or self-care,' 'visit a physician's office,' 'use emergency room service,' 'immediately visit emergency medical center,' was 66.7%, 70.1%, 64.0%, and 92.6%, respectively. Overall, caller's compliance and satisfaction rate were 75.95% and 68.4%, respectively. Logistic regression models showed no significant association between the cardinal dispatcher questions and appropriate triage of trauma patients. CONCLUSION: The recognition level of the emergency medical information center was very low. This result indicates that some new strategies are needed to increase community knowledge and usage of the emergency medical information center. The utilization pattern of emergency medical information center was similar to that of emergency room. It is expected that non-urgent patients could be diverted from overcrowded emergency medical centers to other medical resources by improving the emergency medical information center. Lastly, if prehospital care is to be improved further, the dispatch protocol should be refined and revised with a comprehensive emergency medical system considered.

Photodynamic therapy (PDT) involves the induction of endothelial cell death or occlusion of blood vessels. On the basis of this mechanism of action, PDT is used in the treatment of predominant classic choroidal neovascularization (CNV), if the classic component is over 50%, and in myopic CNV. This study describes 2 cases of distinctive, abnormal, large, subretinal new vessels that are thought to have originated from the choroids. Diminishment of the new vessels was observed following treatment with PDT.

BACKGROUND: For the early detection and prevention of diabetic neuropathy, it is important to identify subclinical diabetic neuropathies. A routine nerve conduction study often fails to detect the early stages of neuropathy. The purpose of this study is to evaluate the clinical usefulness of electrophysiological indexes including the residual latency(RL), terminal latency index (TLI) and modified F ratio (MFR) in detecting early diabetic neuropathy with no objective clinical or electrophysiological abnormalities. METHODS: A nerve conduction study of the upper/lower limbs was investigated in 38 subclinical diabetic neuropathy patients with normal nerve conduction studies (group I), 35 clinical diabetic neuropathy patients with normal nerve conduction studies (group II) and 31 normal controls. RL, TLI and MFR were calculated and compared among the groups. RESULTS: Compared with the control group, the MFR of the lower limbs and TLI of both the upper/lower limbs were significantly decreased in both group I and II (p<0.05). RL was increased in both groups, but the difference was not statistically significant. Comparing the indexes between group I and II, there was no significant difference. CONCLUSIONS: RL, TLI and MFR are useful indexes for reflecting distal conduction slowing especially in slowly progressing polyneuropathies such as diabetic neuropathy. The results also suggest that electrophysiological changes veiled in a routine nerve conduction study were present before the clinical manifestations.
