[A statistical approach to Yatabe-Guilford personality inventory and manifest anxiety scale of the elderly].

In nursing, if we know an elderly person's mental condition, and that which does not make him/her too tired, this method can be very useful. Using this method we predicted the MAS score from scores of Y-G scales. We obtained the MAS score results by the following formula: MAS score not equal to 0.31 X Lack of objectivity +0.41 X Inferiority feelings -0.15 X Ascendance +0.34 X Y-G Nervousness +0.30 X Y-G Depression +9.54.

Reoperation in patients with biliary atresia.

Twenty-seven reoperations were done on 23 patients among 100 infants with biliary atresia who have been treated at Tohoku University Hospital between 1971 and 1981. Nineteen patients had a single reoperation and 4 patients had 2 reoperations. We present the results and the role of reoperation in biliary atresia patients in our institution. Excellent bile drainage after reoperation was obtained in 13 of 15 patients with good bile flow after the initial operation. On the contrary, good bile drainage was not obtained by reoperation in 8 of 12 cases without active bile flow after the initial operation. Cessation of bile flow after successful initial operation is an absolute indication for reoperation. Aggressive reoperations under proper indications improve the surgical results in biliary atresia patients.

Studies on the changes of serum bilirubin level after surgery in biliary atresia.

In biliary atresia, one-fourth of the patients showed prolonged jaundice in spite of a good excretion of bile after surgery. To investigate the cause of jaundice, factors related to the serum bilirubin level were examined in 28 recent cases. Furthermore, clinical analysis was performed in 86 cases of good excretion of bile after surgery. The following results were obtained: The daily amount of bilirubin excretion in bile and bilirubin concentration play an important role in decreasing the serum bilirubin level. The most important factor for prolonged jaundice is ascending cholangitis. Shortening of the life span of the red blood cells is one of the causes of prolonged jaundice.

The histology and fine structure of glands in the rat respiratory tract.

The structure of rat respiratory glands has been investigated by light and electron microscopy. The glands exhibited a tubulo-acinar organization. Individual secretory units were composed of serous tubules or serous demilunes and mucous tubules with narrow lumens at the blind end (proximally), and of mucous ducts with wide lumens which opened to the tracheal lumen distally. Near the junction of the duct with the trachea, mitochondria-rich cells and a few ciliated cells were interspersed with mucous cells. It was found that the histology as well as the ultrastructure of the secretory product of these gland cells varied depending upon the location of the glands in the airway. For this reason, the glands of the epiglottis, larynx and trachea have been described separately. Epiglottal glands consisted of many mucous tubules, a few serous elements and an occasional mucous duct. Laryngeal glands contalned many serous and mucous tubules and a few mucous ducts. Tracheal glands were composed of serous tubules, a few mucous tubules and prominent bucous ducts. Serous tubule cell granules formed a uniform population within a cell profile but varied in cells of the epiglottis, compared with those of the larynx and trachea. Granules in mucous tubule cells differed from those of serous cells. Mucous cell granules also appeared uniform within a single cell but differed from cell to cell and at different levels of the respiratory tract. A particular granule type was predominant at each level. Cells of mucous ducts differed somewhat from those of mucous tubules and comprised two general secretory cell populations. Proximal mucous duct cells contained abundant granules that generally resembled those of mucous tubule cells but were localized in two areas of the cytoplasm. Dilated cisternae of rough endoplasmic reticulum with a bizonal content similar in density of zones seen in mature granules further characterized proximal mucous duct cells. The distal mucous duct cell generally contained sparse apical granules and lacked dilated rough endoplasmic reticulum.

Complex carbohydrates of rat tracheobronchial surface epithelium visualized ultrastructurally.

Application of cytochemical methods for complex carbohydrates at the light and electron microscopic levels served further to differentiate secretory cells of the rat tracheobronchial surface epitheliuim into serous and mucous categories, and permitted subclassification of serous cells into four types and of mucous cells into three types. The granules in different serous cells and Clara cells varied in staining with the periodic acid-thiocarbohydrazide-silver proteinate (PA-TCH-SP) method, but generally lacked dialyzed iron (DI) affinity and apparently contained neutral glycoprotein. However, in some focal areas, serous and Clara cell granules showed a pattern of DI staining similar to the PA-TCH-SP reactivity. The PA-TCH-SP and DI methods stained granule glycoconjugate comparably in the three mucous cell types. The lack of high iron diamine (HID) affinity in these sites testified to carboxylated, periodate-reactive mucosubstance, presumably sialylated glycoprotein. The luminal surface of the apical plasmalemma of all surface epithelial cells stained with DI but lacked HID affinity. The PA-TCH-SP technique stained the surface of the apical plasmalemma of mucous cells, serous cells, and Clara cells in decreasing order of intensity. Microvilli of cililated cells were PA-TCH-SP-positive, but cilia were unreactive and apparently contained a glycosaminoglycan rather than the presumed sialylated glycoprotein of the other surfaces. DI and PA-TCH-SP reactivity of the apical far exceeded that of the basolateral plasmalemma in all surface epithelial cells. Two strata, presumed to be the lamina lucida and the lamina diffusa of the basement membrane under all the surface epithelial cells, stained with the DI but not the PA-TCH-SP method and apparently contained glycosaminogycan. Intraepithelial cells, interpreted as globule leukocytes, appeared to represent mast cells infiltrating the epithelium and carrying out endocytic activity.
