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.

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.

Respiratory distress syndrome (RDS) of preterm infants remains a significant cause of morbidity and mortality despite improvements in neonatal intensive care and artificial ventilatory techniques. After identification of the deficiency of pulmonary surfactant is major pathophysiologic basis in RDS, artificial surfactant replacement therapy in RDS was first successfully tested by Fujiwara and co-workers in 1980. therefore, exogenous surfactant replacement produced exellent results in improved clinical and repiratory status during the acute period and decreased incidence of late complications and mortality. According to comparison of administration timing between early (within 6 hours after birth) and late (after 6 hours)group, early replacement therapy is more effective in improving of clinical course and prognosis. Because of that, early, just after birth, recognition and detection of RDS is also important procedure. There are many investigations and methods for the detection of RDS in prenatal or postnatal period. Among then, stable microbubble rating (SMR) test was a simple method and SMR test has a higher diagnostic accuracy. To determine the relation of the SMR and purified natural surfactant (PNS) concentration in vitro, the author conducted each 5 times test of SMR method according to 5 groups of PNS concentration by using modified Pattle's method. The results were as follows: 1) The mean and standard deviation of SMR according to 5 groups of PNS concentration were 119.4 (15.0in 20mug PL (phospholipid)/ml, 452.2 (160.2 in 40mug PL/ml, 879.0 (93.4 in 60mug PL/ml, 1311.8 (274.8in80mug PL/ml, 1710.6(272.3 in 100mug PL/ml. 2) The regression curve of SMR and PNS concentration showed statistically significant relation(p<0.005). In conclusion, the SMR test was a good method in estimation of surfactant concentration in vitro and also in diagnosis of RDS recognized as a surfactant deficiency. In the future, we expected that prophylactic surfactant replacement therapy. immediate after birth, will be more popular in the field of neonatal care of RDS. So, we recommended the use of this method for early detection and serving optimal care of RDS.

The purpose of this paper is to investigate the extent of destruction Blood-ocularbarrier between colored rabbits and white rabbits after photocoagulation, as preliminary experiment for the using colored and white rabbits. A total of 10 rabbits (5 white rabbits, 5 colored rabbits) were used. Photocoagulation in the right eye of 5 white rabbits and 5 colored rabbits were performed. The left eye of all the rabbits was control eye and the right eye was laser treated eye. After 3 days, a dose of 25mg/kg of 10% fluorescein sodium was injected in the ear vein of rabbit intravenously. We sampled aquous humor in anterior chamber and vitreous, and checked fluorescein concentration in anterior chamber and vitreous using HPLC (High Performance Liquid Chromatography). The results obtained were as follows; In experimental animals, 1. There is no significance between colored rabbits and white rabbits in fluorescein concentration of vitreous and aquous humor in control group. 2. The concentration of the fluorescein in the anterior chamber and vitreous of the right photocoagulated eye was higher than control eye, but there is no significance between colored rabbits and white rabbits. 3. there is no significance between colored rabbits and white rabbits in extent of destruction of Blood-ocular-barrier after Laser photocoagulation.

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.
