Acquired perforating disease(APD) is characterized by hyperkeratotic papules with transepidermal elimination of degenerated material and is associated with renal disease and/or diabetes. Particular attention has been directed to transepidermal elimination because the articles on perforating diseases among patients with chronic renal failure and/or diabetes have been increasingly reported. We describe four patients with chronic renal failure and/or diabetes whose skin biopsy specimens showed transepidermal elimination.

It is interesting and in important to study histochemical changes of glucose-6-phosphatase (G-6-Pase) activity by electron microscopy in order to promote the knowledge needed for diagnosis and prognosis in such liver diseases as von Gierke's disease, hepatoma and various other hepatocellular alterations of different origins. Since we had not accomplished the electron microscopic demonstration of G-6-Pase, although light microscopic studies on changes of the enzyme activity were done in this laboratory, this investigation was planned to obtain a satisfactory technique for ultrastructural demonstration of the enzyme activity. Unfixed frozen sections (80 micro thick) of mouse liver were washed for 2~3 minutes in a 0.4M sucrose solution (pH6.8) containing 4 mM lead nitrate and then incubated for 15~20 minutes at 32~37 degrees C in several different media to which 0.4M sucrose solution was added: A) a modification of the original Chiquoine medium, B) the first modification of the Wachstein-Meisel medium C (the second modification; the 2% lead nitrate solution was reduced in amount to 1.5 m1 instead of 3.0 ml in the medium-B). After incubation, these sections were fixed in 1% osmic acid containing sucrose, followed by embedding in Epon, ultrathin-section, mounting and staining with uranyl acetate and/or lead nitrate. By incubating the sections in the medium (B or C), satisfactory preparations were obtainable for its electron microscopic demonstration. The granular deposits of reaction products were found characteristically on the membranous component of the rough-and smooth-surfaced endoplasmic reticulum and unclear envelope. Occasional deposits were observed within cisternae or vesicles, in the nucleus, and immediate1y adjacent to the cisternal membrane and glycogen areas.

Prednisolone, a cortisol analogue, was given intraperitoneally to rats with 5, 10 or 15 doses of 5 mg. per kg. of body weight per day. Sacrificing the animals 24 hours after the last injection, unfixed frozen sections from small pieces of liver tissue were incubated and stained by a modification from the method of Wachstein and Meisel(1965) for glucose-6-phosphatase (G-6-Pase) activity. Some of the tissue blocks were processed for staining with hematoxylin and eosin for histopathological observation. Glucose-6-phosphatase activity, being represented histochemically by brownish-black deposits, was progressively increased after administrations 5 or 10 times. With 15 doses of prednisolone the general histochemical picture of G-6-Pase activity appeared to be similar to that of the control group, except for a different distribution of hepatocytes possessing strong activity. In prednisolone treated rats, the swollen hepatocytes showed a marked, cytoplasmic vacuolization and nuclear pyknosis, particularly in the periportal and midzonal areas of hepatic lobules. Some discussion of the G-6-Pase corticosteroids are presented in terms of their metabolic effects.

BACKGROUND: This study was designed to describe the current tends of emergency tracheal intubation and predict difficult airway intubations in emergency department (ED) at a teaching hospital in Korea. METHODS: All patients who was taken endotracheal incubation in ED during a 1-year period (Mar 1997 through Feb 1998) were included in the study population. Medical records of the patients were retrospectively reviewed. Among them, 56 patients were prospectively evaluated parameters to predict difficult airway intubations. RESULTS: During the study period, a total of 413 patients(1.5%) required endotracheal intubation. Except far 2 cases, all patients intubated orotracheally, and 298(72%) patients were intubated by emergency medicine resident. Pharmacologic adjuncts were used in 200(48%) patients, the neuromuscular blocking agent(NMBA) was used in 16(3.8%) Commonly used drugs were thiopental and vecuronium. The difficult incubation was not associated with presence of denture, length and circumference of neck, and mental status. The visibility of vocal cord on laryngoscopy significantly correlated to the difficult airway. CONCLUSION: At this institution, the majority of ED incubation were performed by emergency physicians and NMBA was not routinely used. The visibility of vocal cord during the direct laryngoscopy could be a predictor of difficult incubation in ED.

PURPOSE: The aim of this study was to evaluate the utility of contrast-enhanced MRI with first-pass and delayed images in prediction of myocardial viability after acute myocardial infarction. MATERIALS AND METHODS: Ten patients (M:F=:4, mean age =6 5 years) with acute myocardial infarction underwent first-pass image after bolus injection of gadolinium (one image/sec for 120sec)and delayed image (7 2 minutes later). According to 60 segments on midventricular level, the assessment of MRI were concerned about location of lesion, depth of lesion, enhancement on first-pass image and enhancement pattern on delayed image. MRI findings were compared with wall motion on resting echocardiography and stress or follow-up echocardiography. RESULTS: 1) MRI findings were classified into 4 types: normal enhancement on first-pass and delayed images (type 1), normal enhancement on first-pass image and nontransmural hyperenhancement on delayed image (type 2), non-transmural enhancing defect on first-pass image and transmural enhancement with endocardial non-enhancing defect on delayed image (type 3), and transmural enhancing defect on first-pass image and transmural hyperenhancement on delayed image (type 4).2) Type 2 suggested viable myocardium and type 3 had high porbability of viability. Type was compatible with non-viable myocardium. CONCLUSION: Enhancing defect on first-pass image and involving thickness on both the first-pass image and delayed image in contrast enhanced MRI may predict myocardial viability.
