It was well known that atrial myocytes systhesize atrial natriuretic peptide[ANP], and secrete it into the atrial lumen through the atrial endocardium. But the mechanism for regulation of ANP secretion has not been clearly elucidated, because there was little information of the atrial morphology concerning basal lamina. Basal lamina is surmised as one of barriers that control the movement of ANP, a large molecule. This study was attempted to elucidate the morphological characteristics of basal lamina and connective tissue fibers of atrial endocardial layer by scanning electron microscopy. Basal lamina was exposed by removal of the overlying endothelium. This was achieved by using OsO4 maceration, immersion in aqueous boric acid or EDTA treatment. After removal of the endothelial cell, the specimens were exposed to ultrasonic vibration in case of need. The external surface of basal lamina showed a fairly smooth appearance on the whole, although a few irregular folds are often encountered. Fenestrations, 0.1-1 micrometer in diameter, were randomly observed on the basal lamina, and they were circular to oval in shape. Margin of fenestrations was somewhat distinct and some was divided into two parts by linear structures. The structural differences of fenestrations between right and left atria were not found. The fibroreticular lamina under the basal lamina was revealed by removal of the endothelial cells and their basal lamina. This layer was consisted of interwoven fine fibers. These fine fibers were repeatedly divided and fused, forming reticular network. Some fine fibers connected with basal lamina. Some connective tissue fibers below fibroreticular layer were collected into thick bundles running parallel to myocytes. Above results may serve as a basis for the physiological and morphological studies of atrium.

A case of linear IgA bullous dermatosis reported. A 32-year-old male with pruritic, papulovesicular eruptions on the whole body of 2 months' duration was examined. He had no history of diarrhea or fou]smellirig stool even though his diet cnntained gluten. A skin biopsy revealed subepidennal vesicles and papillary microabscesses infiltrated by many neutrophils and some eosinophils. Direct irnmunofluorescent examination of the perilesional skin showed a linear deposition of IgA along the basement mernbrane zone. The lesions responded rapidly to oral dapsone and topical steroid therapy but recurred whenever the oral mcdication was discontinued.

Pemphigua foliaceus is a rare, relatively mild and chronic variety of pemphigus which is characterized by superficial flaccid bullae which show acantholytic changes in the upper part of the epidermis histopathologically. We report herein five cases of pemphigus foliaceus. The patients had erythematous and crusted patches chiefly on face, chest and back areas, except for case 2 who had flaccid bullae on the upper extrimities. The diagnosis of all these patients were confirmed by immunofluorescence studies. Among these five patients, one was recognized as a rifampicin induced pemphigus foliaceus, and the other one revealed concurrent lesions of psoriasis.

We present here, a case of pemphigus erythematosus developed in a 31-year-old woman, who had been suffering from repeated episode, of remission and exacerbation with several erythematous, and somewhat oozing patche accompanying a mild pruritus or her face, upper part of the back and anterior chest. In serological studies, she had antinuclear antiboc@lies at. a titer of 1:160. Histopathological finding showed subcorneal bullae. Immunofluorescent study revealed IgG and C, deposition in the intercellular space of the epidermis and along the de rmoepidermal junction.

The author studied the 240 cases of strabismus patients in our OPD from 1972 to 1976. And the author observed the results of occlusion therapy in 55 cases of amblyopia with strabismus. The results are as follows: The sex distribution in exotropia patients showed a preponderance in female sex, the ratio male to female being 2:3. Concerning the refractive status, there were more hyperopia in esotropia and more myopia in exotropia. The amount of deviation was about the same at the near and distance, most patients had a basic type and distributed between 21-40 prism. Of all patients in whom a determination of the retina correspondence could be made, 70% showed NBC and 25 % showed ARC 5% showed variable. Ninety percent of the strabismic amblyopia patients was successfully treated by occlusion therapy. A positive correlation was not found between the duration of occlusion and the age at which occlusion was started. Amblyopes showed arrest of improvement after a certain period, about 3 to 4 months. The exotropia patients over the age of 7 showed good results by occlusion. The shorter the time between the age at which occlusion was started and the onset of strabismus, the better was the result. Strabismic amblyopia responded well to conventional occIusion.
