Ultracytochemical Studies on Lining Layer of Lung Alveoli

Ultramorphological and ultracytochemical studies on tubuloreticular structures in lymphoid cells.

Tubuloreticular structures that are frequently present in the cytoplasm of lymphoid cells grown in vitro were studied with cytochemical methods at high resolution. The structures are easily digested by Pronase and pepsin; they are not sensitive to trypsin or RNase. From the results obtained, we conclude that the tubuloreticular structures are of proteinaceous nature and that they are mainly com...

Lung alveoli: endogenous programmed destruction and regeneration.

Mammalian alveoli, complex architectural and cellular units with dimensions that are linked to the organism's O2 consumption (VO2), are thought to be destroyed only by disease and not to spontaneously regenerate. Calorie restriction of adult mammals lowers VO2, and ad libitum refeeding returns VO2 to pre-calorie-restriction values. We took advantage of these relationships and tested the hypothe...

Absorption of Albumin from Alveoli of Perfused Dog Lung.

SCHULTZ, ALVIN L., JEROME T. GRISMER, SHOHACHI WADA, AND FRANCISCO GRANDE. Absorption of albumin from alveoli of perfused dog lung. Am. J. Physiol. 207(6) : I 300-1304. 1g64An iodinated albumin solution was instilled into the isolated perfused dog lung through a bronchial catheter. During the 5hr period following instillation, 6.4% of the iodinated albumin dose was absorbed from the lung into t...

The alveolar lining layer. A review of studies on its role in pulmonary mechanics and in the pathogenesis of atelectasis.

Ultracytochemical and light microscopic histochemical studies in murine leprosy.

It is an established fact, that human leprosy is characterized by its variation in the ability to mount and maintain cell-mediated immune (CMI) response against Mycobacterium leprae and thereby to control the infection. Tuberculoid leprosy patients exhibit strong CMI against M. leprae(1-3), they have few lesions in which few or no bacilli ace found. On the other hand, patients with lepromatous ...
