The Effects of Structural Alterations in the Polyamine and Amino Acid Moieties of Philanthotoxins on Nicotinic Acetylcholine Receptor Inhibition in the Locust, .

Alterations in the polyamine and amino acid (tyrosine) moieties of philanthotoxin-343 (PhTX-343) were investigated for their effects on the antagonism of nicotinic acetylcholine receptors (nAChRs) isolated from the locust () mushroom body. Through whole-cell patch-clamp recordings, the philanthotoxin analogues in this study were shown to cause inhibition of the inward current when co-applied with acetylcholine (ACh). PhTX-343 (IC = 0.

Pancreatitis-associated protein protects the lung from leukocyte-induced injury.

Background: Severe pancreatitis is often complicated by shock and acute lung failure. Little is known about the pathophysiologic impact of the 16.6-kD lectine, named pancreatitis-associated protein (PAP), which is expressed during pancreatitis and which reduces mortality in a rat model with severe pancreatitis.

Lipid and lipoprotein (a) concentrations in renal transplant patients.

Lipid and lipoprotein concentrations, including lipoprotein (a), were measured in 67 clinically stable renal allograft recipients and compared with age- and sex-matched controls. Median lipoprotein (a) concentrations were significantly elevated in the transplant group (P = 0.048), with the distribution of apoprotein (a) isoforms being similar between the two groups.

Bone disease after jejuno-ileal bypass for morbid obesity.

Fifteen patients who had undergone a 14 inches X 4 inches jejuno-ileal bypass operation for obesity, 3 to 4 years earlier, were investigated by iliac bone biopsy, radiology and routine biochemistry, including 25-hydroxy-vitamin D and parathyroid hormone estimations. Two patients had histological osteomalacia which was mild in one. A further 9 patients had abnormal bone biopsies, there being an excess of trabecular bone surface covered by osteoid with a normal or reduced amount of calcification front.

The effect of aluminium hydroxide orally on calcium, phosphorus and aluminium metabolism in normal subjects.

1. Five normal subjects were given 100 ml of aluminium hydroxide gel per day for 28 days. 2.
