Genus of aspergilli are ubiquitous saprophytic molds in nature, which are recognized about 700 species, at least eight are pathologic for human. Pulmonary aspergillosis is rare disease, most frequent presenting as secondary invasion, and aspergillosis of the nasal cavity is the most common sites of the extrapulmonary aspergillosis. Predisposing factors for pulmonary aspergillosis are chronic lung disease, tuberculosis, antibiotics, cytotoxins and neoplasia, hematologic disorders, and histoplasmosis etc. Authors have experienced 10 cases of pulmonary aspergillosis and a case of aspergillosis of nasal cavity in Dept. of Pathol. Chosun univ. hospital and christian hospital from Feb. 1981 to July 1984. Patient of pulmonary aspergillosis are received surgical resection and survived well without complications.

Although this vascular anomaly, angiomatosis retinae, was initially observed over 85 years ago, and although excellent clinical description of the lesion exist in the literature, treatments for the angiomatosis retinae is difficult and unless the condition is in its early stages, impossible but available symptomatic therapy. Two cases of the angiomatosis retinae, the first, 11 year old girl, von Hippel disease, early stage of vascular dilatation and angiomatous formation, and the second, 15 year old boy, von Hippel-Lindau disease, the final stage of glaucoma and destruction of the eye, are reported. Intravenous fluorescein angiography has been demonstrated, the retinal vascular malformations in von Hippel-Lindau disease are distributed focally and not diffusely, The retinal veins showing greater changes than the arteries are disclosed. This paper presents the fluorscein angiographic findings of von Hippel-Lindau disease and discusses the treatments and the pathologic findings of angiomatosis retinae with literatures related to von Hippel-Lindau disease.

The effect of peripheral nerve on limb growth and maturation has received little attention after the limb differentiation stage. This study investigated the effects of paralysis (loss of function) on growth of bones in the hind limb of Hymenochirus boettgeri. Complete denervation of the right sciatic nerve was performed at stages 63 and 66, animals were sacrificed after 6 and 7 (Groups I and II) and 12 and 13 (Groups III and IV) weeks. Denervation was assessed by degree of paralysis. Specimens were cleared and double stained with alcian blue and alizarin red for cartilage and bone. Length and area of right and left femurs and length of right and left tibia were measured by using an image analyzer program after photographing, and the ratio of right to left femur length and area was calculated. There were no gross morphological differences between the control and sham groups. In the experimental groups, the ratio of femur length was 93.71% and 95.70% in Group I and II, and 96.12% and 96.06% in Group III and IV. The ratio of tibia length was 94.05% and 96.15% in Group I and II, and 98.12% and 98.22% in Group III and IV. The ratio of femur area was 90.43% and 95.61% in Group I and II, and 96.08% and 95.73% in Group III and IV. Comparison between control and experimental groups showed statistically significant (p<0.05). There was a histologically maturational delay in proximal end of denervated hind limb, comparing with opposite side. These results suggested that denervation of sciatic nerve affect directly the growth and maturation of hind limb bones in Hymenochirus boettgeri and loss of critical period of bony maturation after denervation.

Proliferations of the endometrial glands form a continuum from focal glandular crowding through simple hyperplasia, complex hyperplasia and atypical hyperplasia to frank adenocarcinoma. But objective criteria to distinguish these proliferative endometrial lesions are not clear-cut and terminology is confusing. The p53 protein is a nuclear phosphoprotein that can regulate cell proliferation and suppress tumor growth. Mutation in the p53 gene have been reported in a variety of human tumors, and in selected malignancies overexpression of p53 has been associated with poor prognosis. In this study we examined a series of endometrial proliferative lesion, including hyperplasia, adenocarcinoma, and adenomyosis to determine whether or not p53 is overexpressed in these lesions. In the result, p53 immunoreactivity was observed in 3 of 17 (17.6%) simple hyperplasia, one of 6 (16.6%) complex hyperplasia, none of 3 (O%) atypical hyperplasia, 6 of 13 (46.1%) adenocarcinoma and none of 10 (O%) adenomyosis. In conclusion, p53 mutation seems to play a role in oncogenesis of endometrial adenocarcinoma in early phase but there was no significant relationship between p53 overexpression and histologic grade of adenocarcinoma.

We evaluated the clinical effects of Nicorandil in 27 patients (17 male and 10 female) with ischemic heart disease (17 patients of stable effort angina, 3 patients of unstable effort angina, 6 patients of spontaneous angina, 1 patient of variant angina) in terms of the effect on the anginal pain, electrocardiographic changes and side effects. The results obtained were as follows; 1. The pulse rate was not changed by the drug administration and blood pressure were decreased slightly by Nicorandil in a daily dose of 15 mg divided into 3 dose, but these decrease were not significant in statistical meaning. 2. Improvement in EKG changes was observed in 9 patients (69%) among the 13 patients who showed abnormal EKG initially. 3. Anti-anginal effect of nicorandil were excellent in 14 patients, good in 8 patients, fair in 3 patients and so the rate of global improvement was 82%. 4. Nicorandil had side effects in 7 patients, headache (4 patients), palpitation, ocular pain, edema, but these were transitory and tolerable except of one case who could not be continued because of severe headache.

BACKGROUND: The surfactant specific proteins, SP-B and SP-C are believed to be important regulators of the surfactant function and homeostasis. Since acute respiratory distress syndrome(ARDS) is usually viewed as the functional and morphological expression of a similar underlying lung injury caused by a variety of insults, and since abnormalities in the surfactant function have been described in ARDS, the authors investigated the different effects of endotoxin and thiourea on the accumulation of mRNA encoding SP-B and SP-C. METHODS: Sprague-Dawley rats were given 5 mg/kg of an intraperitoneal endotoxin from Salmonella enteritidis and 3.5 mg/kg intraperitoneal thiourea and were sacrificed at different time periods. RESULTS: 1. The SP-B mRNA levels 6 and 24 hours after the 5 mg/kg endotoxin treatment was significantly reduced by 26.1% and 50%, respectively(P<0.01, P<0.001). 2. The SP-B mRNA levels 24 hours after the 3.5 mg/kg thiourea treatment was reduced by 9.8% and 12.5%, respectively. 3. The SP-C mRNA levels 6 and 24 hours after the 5 mg/kg endotoxin treatment was significantly reduced by 38.7% and 53.6%, respectively(P<0.01, P<0.001). 4. The SP-C mRNA level 6 hours after the 3.5 mg/kg thiourea treatment was reduced by 22.8%(P<0.05). CONCLUSION: These results indicate that the differential regulation of the hydrophobic surfactant proteins in vivo is evident, and suggest that the hydrophobic surfactant proteins might be differentially regulated during lung injury at different time periods without altering the lung wet to dry ratios. The mechanism of these alternations at the different time periods and the different kinds of etiology remain to be determined.

BACKGROUND: Surfactant protein A (SP-A) is important in the regulation of surfactant secretion, synthesis and recycling. SP-A has important roles in regulating surfactant metabolism as well as in determining surfactant's physical properties. Since systemic sepsis is one of the common causes of acute respiratory distress syndrome (ARDS) and abnormalities in surfactant function have been described in ARDS, the authors investigated the effects of endotoxemia on the accumulation of mRNA encoding SP-A and SP-A protein content. METHODS: Adult rats were given various doses of intraperitoneal endotoxin from Salmonella enteritidis and sacrificed at different times. SP-A mRNA was measured by filter hybridization method. Lung SP-A protein content was determined by double sandwich ELISA assay using a polyclonal antiserum raised in rabbits against purified rat SP-A. RESULTS: 1) The accumulation of SP-A mFNA in the endotoxin treated group 24 hours after 2mg/kg and 5mg/kg endotosin treatments was significantly increased 50.9% and 27.3%, respectively, compared to the control group (P<0.001, P<0.025). 2) The accumulation of SP-A mRNA 24 hours in the 5mg/kg endotoxin treated group was significantly increased by 26.5% compared to the control group (P<0.01). 3) Total amount of lung SP-A was not altered at 24 hours by various doses of treatment. Total lung Sp-A content 144 hours after endotoxin administration was significantly decreased by 51.4% compared to the control group (P<0.01) CONCLUSIONS: The specific regulation of SP-A by various time course in vivo is evident. The late decline in SP-A protein content was unexpected and suggests that SP-A may be differentially regulated during lung inflammation. The functional significance of these alterations remains to be clarified.
