Ten anesthetized dogs, 48 h postintravenous 131I-albumin injection, had a segment of lung airspace isolated by a balloon-tipped catheter lodged in a bronchus. An isotonic saline solution containing trace amounts of Blue Dextran, 125I-albumin, and 57Co-cyanocobalamin was instilled into the lung
The permeability of the alveolar epithelium following alloxan challenge was studied in dogs by determining transfer of radiolabeled solutes between alveolus and blood. Two days after injection of 131-Ialbumin into the blood, anesthetized dogs had the air space of part of one lung isolated by a
In this study, the anti-nociceptive and anti-inflammatory effects of cyanocobalamin (Vit B12) against acute and chronic pain and inflammation were evaluated in mice. Vit B12 (0.87, 1 and 1.77 mg/kg) were injected intraperitoneally. The anti-nociceptive effects against acute pain were examined using
BACKGROUND
Vitamin B12 and alpha lipoic acid (ALA) are known to promote functional and morphological recovery after peripheral nerve injury.
OBJECTIVE
To compare the regenerative and neuroprotective effects of vitamin B12 and ALA treatment after sciatic nerve injury.
METHODS
A total of 40 rats were
Microvascular permeability was studied in the isolated perfused rat pancreas using a rapid multiple indicator-dilution technique. Capillary extractions, permeability-surface area products (PS), and extravascular volumes of distribution (EVV) were determined for 22Na+, 51Cr-labeled EDTA,
BACKGROUND: To date, only case reports or small studies have documented the syndrome of food-cobalamin malabsorption in specific populations of patients or situations. In this paper, we present the data from 80 unselected patients with cobalamin deficiency related to food-cobalamin malabsorption.
OBJECTIVE
Approximately 15% of people over 60 years old have a cobalamin (Cbl) deficiency in relation with a food-cobalamin malabsorption (FCM). But to date, only case reports or small series have been reported. The aim of this study was to describe the clinical characteristics of the FCM in old
Investigation of the clearance of proteins from the air spaces is important for an understanding of the resolution of pulmonary edema and also because of current interest in delivery of therapeutic peptides via the distal air spaces. Few experimental studies have examined the size dependence for
We measured the effects of 100% O2 exposure at 1 atm for 48 (n = 5) and 63 h (n = 6) on the solute permeability of the alveolar epithelium of rabbits. We instilled 10-15 ml of saline containing trace amounts of 131I-albumin (r approximately 35 A), 125I-cytochrome c (r approximately 17 A), and
In rabbits exposed to 100% O2 at 1 ATA from 48 to 72 h, we measured the accumulation of intravenously injected 125I-bovine albumin, [57Co]cyanocobalamin, and 51Cr-erythrocytes in the intestine, skeletal muscle, heart, and lungs. From these data, we calculated the extravascular albumin and
Perilla ketone (PK) is a potent lung toxin that causes increased microvascular permeability pulmonary edema in grazing animals. Because the mechanism of action of PK is not know, we investigated whether PK directly affects endothelial cells. Bovine aortic endothelial cells were grown to confluence
