BACKGROUND: Packs are viscous preparations that produce a film over the skin surface, thus preventing the evaporation of water and increasing the skin temperature. Because of this occlusive effect, packs can be used as the vehicle to which active pharmacologic agents produce a therapeutic effect. OBJECTIVE: This study aimed to explore the feasibility of pack formulation as a vehicle by comparing percutaneous absorption with ointment formulation. METHODS: After 0.5, 1, 2 and 6 hours of topical applications of 0.05% clobetasol 17-propionate ointment and pack on each forearm of 9 young, healthy male subjects, the amounts of the drug in tape-stripped stratum corneum were assessed using high performance liquid chromatography(HPLC). RESULTS: There was no significant difference with regard to the amount of the drug in tape-stripped stratum corneum between ointment and pack formulations of 0.05% clobetasol 17-propionate. CONCLUSION: Pack formulations delivered similar amount of drugs to the skin compared to ointment formulations, suggesting peel-off type pack can be used as a new vehicle of topical corticosteroids.

BACKGROUND: The most important acute complication of percutaneous transluminal coronary angioplasty (PTCA) is abrupt closure by dissection and thrombus, which account for the majority of deaths and emergency coronary artery bypass procedures associated with PTCA. We sought to determine the relationship between clinical, angiographic characteristics and abrupt thrombotic closure related to coronary intervention. METHODS: One hundred thirty two patients (61.6+/-8.0 year, 98 male) underwent PTCA or stenting under the diagnosis of acute myocardial infarction were analyzed at Chonnam University Hospital between Jan '97 and Jun '98. Patients were divided into two groups, one, 14 patients (Group A, 61.7+/-8.0 year, 9 male), who developed thrombotic occlusion, and the other, 118 patients (Group B, 61.5+/-8.0 year, 89 male) who did not develop abrupt closure related to the coronary intervention. RESULT: There were no significant differences in age, sex, risk factors, activated partial thromboplastin time, fibrinogen, erythrocyte sedimentation rate, C-reactive protein, location of lesion, branch involvement, lesion severity, AHA/ACC morphology between two groups. The incidence of intra-coronary thrombus was greater in Group A than in Group B (44% vs. 2%, p=0.025). Acute thrombotic occlusion related to the coronary interventions developed more frequently in the lesions within two days after the symptomatic onset (55% vs. 19%, p=0.035) and in the right coronary artery (RCA) lesions (55% vs. 24%, p=0.041). CONCLUSION: Predictors of abrupt thrombotic occlusion during coronary intervention in patients with acute myocardial infarction are intracoronary thrombus, earlier intervenion within 2 days after onset of aucte myocardial infarction and RCA lesion.

BACKGROUND AND PURPOSE: Negative findings on diffusion-weighted imaging (DWI) does not exclude the possibility of brainstem infarction, particularly in the acute stage of medullary lesion. Our aim was to investigate the false-negative rate of DWI in patients with acute lateral medullary infarction. METHODS: We applied DWI to 26 patients with a clinical diagnosis of lateral medullary infarction within 72 h of the onset. We assessed relationships between initial DWI findings and time-to-MRI (the time between onset of symptoms and initial DWI), number of clinical symptoms and signs, and final lesion volume. RESULTS: There were 8 cases (31%) of false negatives in the initial DWI results. The occurrence of false-negative DWI findings decreased significantly as the time-to-MRI increased (P=0.014). However, the false-negative rate was not significantly correlated with the number of clinical symptoms and signs or the final lesion volume. CONCLUSIONS: The diagnosis of lateral medullary infarction should not be ruled out on the basis of early negative DWI. To confirm the lesion, follow-up DWI or further MRI should be performed in cases with early negative DWI results

BACKGROUND AND OBJECTIVES: Macrolide is a relatively effective drug in chronic bronchiolitis and chronic sinusitis with mucous hypersecretion. However, the anti-secretory effect of macrolide is not clear. The aim of this study was to evaluate the effect of macrolide on the interleukin -1beta (IL-1beta)-induced MUC2/5AC genes expression and mucin secretion. Matrials and Methods: We observed effects of roxithromycin and clarithromycin on the IL-1beta-induced MUC2/5AC genes expression and mucin secretion in cultured human airway NCI-H292 epithelial cells. The steady state mRNA levels of MUC2/5AC and mucin secretion were determined by reverse transcriptase-polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay. RESULTS: Roxithromycin attenuated the IL-1beta-mediated MUC2/5AC genes expression and mucin secretion. When roxithromycin treated before exposure to IL-1beta and after exposure to IL-1beta in cultured cells, both treatment methods inhibited the IL-1beta-induced MUC2/5AC genes expression and mucin secretion. However, clarithromycin did not suppress the IL-1beta-mediated MUC2/5AC genes expression and mucin secretion. CONCLUSION: This result suggests that roxithromycin inhibits the IL-1beta-mediated mucin secretion through inhibition of MUC2/5AC genes expression.

Backgroud and Objectives: There are few reports about long-term outcomes of transnasal endoscopic marsupialization of isolated maxillary sinus mucocele. The approach routes of endoscopic marsupialization in those papers were mainly through middle meatal antrostomy. However, it is difficult or impossible to treat maxillary sinus mucocele by transnasal endoscopic middle meatal antrostomy in some cases. The aim of this study was to investigate long-term outcomes of transnasal endoscopic marsupialization according to three different approach routes. Materials and Methods: We reviewed 20 consecutive patients underwent transnasal endoscopic marsupialization and followed up for at least 66 months, retrospectively. Ten patients were treated by transnasal endoscopic middle meatal antrostomy with marsupialization, four by inferior meatal antrostomy and six by extended middle meatal antrostomy. RESULTS: No evidence of recurrence and major complications were observed during follow-up periods ranging from 66 to 102 months (mean, 80 months) according to three different approach routes. CONCLUSION: Transnasal endoscopic marsupialization with the appropriate antrostomy route according to the location and bulging direction of maxillary sinus mucoceles is considered to be an effective therapeutic method with favorable long-term outcomes

BACKGROUND: The p53 and retinoblastoma(Rb) tumor suppressor genes are associated with the pathogenesis of several types of human cancer. Substantial. proportion of the primary lung cancers or cell lines have been reported to have the p53 and/or the Rb gene mutations. But so far there is no report on the analysis of the Rb gene polymorphism as one of the genetic susceptibility marker. This study was undertaken to establish the gene frequencies of the polymorphic genotypes of the p53 and Rb genes in Koreans to evaluate the possible involvement of these genotypes as a risk factor of lung cancer. METHODS: In this study 145 controls without previous and present tumor history and 128 lung cancer patients were subjected to analysis The two intragenic polymorphisms of the p53 gene(exon 4/AccII, intron 6/MspI) and one intron 17/XbaI polymorphism of the Rb gene were analysed by the method of polymersae chain react lion-restriction fragment length polymorphisms(PCR-RFLPS). The genotype of the intron 3/16 bp repeat polymorphism of p53 was determined by PCR and direct gel electrophoresis. RESULTS: There were no significant differences in the genotype distributions of the p53 gene between lung cart cert patients and controls. But heterozygotes(Arg/Pro) of the exon 4/AcclII polymorphisms were slightly over-represented than controls, especially in the Kreyberg type I cancer, which was known 13 be associated with smoking. The intron 3/16 bp duplication and the intron 6/MspI polymorphisms were in complete linkage disequilibrium. About 95% of the individuals were homozygotes of the common alleles both in the 16 duplication and MspI polymorphisms, and no differences were deteced in the genotype distributions between lung cancer patients and controls. Overall genotype distributions of the Rb gene polymorphisms between lung cancer patients and controls were not significantly different However, the genotype distributions in the Kreyberg type I cancer were significantly different from those of controls(p=0.0297) or adenocarcinomas(p=0.0008). It was noticeable that 73.4% of the patients with adenocarcinomas were heterozygotes(r1/r2) whereas 39.2% of the Kreyberg type I cancer were heterozygous at this polymorphisms. In the lung cancer patients, significant differences were a]so noted between the high dose smokers and low dose smokers including non-smokers(p=0.0258). The relative risk to Kreyberg type I cancer was significantly reduced in the individuals with the genotype of r1/r2(odds ratio=0.46, 95%C.I.=0.25-0.86, p=0.0124). The combined genotype distribution of the exon 4/AccII of the p53 and the intron 17 Rb gene polymorphisms in Kreyberg type I cancers were significantly different from dose of controls or adenocarcinomas. The highest odds ratio were observed in the individuals with the genotypes of Arg/pro and r2/r2(odds ratio=1.97, 95%C.I.=0.84-4.59) and lowest one was in the patients with Arg/Arg, r1/r2 genotype(odds ratio=0.54, 95%C.I.=0.25-1.14). CONCLUSION: The p53 and the Rb gene polymorphisms modulate the risk of smoking induced lung cancer development in Koreans. However, the exact mechanism of risk modulation by these polymorphism remains to be determined. For more discrete clarification of associations between specific genotypes and lung cancer risk, the evaluations of these polymorphisms in other ethnics and more number of patients will be needed.
