1. Antibodies were raised in rabbits against pure rat angiotensinogen. The antisera obtained were highly specific for rat angiotensinogen and did not bind hog, dog, rabbit, monkey or human angiotensinogen. They did not cross-react with angiotensin I, angiotensin II or synthetic hog tetradecapeptide renin substrate. However, rat des-angiotensin I-angiotensinogen cross-reacted 100% with the angio...

This study shows the expression at the cell surface of human thymic epithelial cells (TEC) of a neurotensin (NT)-like immunoreactivity. NT radio-immunoassay (RIA) revealed that cultured human TEC contain +/-5 ng immunoreactive (ir) NT/10(6) cells, of which 5% is associated with plasma cell membranes. HPLC analysis of NT-ir present in human TEC showed a major peak of NT-ir corresponding to NT1-1...

A pressor material in human stable plasma protein solutions is described, and evidence that this material may be angiotensin II is presented. When six samples of stable plasma protein solution were assayed against standard angiotensin in the sensitive, ganglioplegic, nephrectomized rat anesthetized with urethane, the levels of pressor activity ranged from 320 to 830 ng/100 ml, with a mean of 55...

By using the sensitive radio-immunoassay specific for rat atrial natriuretic peptide (rANP) combined with chromatographic separation, we have determined molecular forms of rANP in rat tissues and plasma. Gamma-rat atrial natriuretic peptide is a major component of rANP in rat atria and ventricles, while alpha-rANP is a predominant form in the plasma, brain and submaxillary gland. Although molec...

for serum ferritin estimation was taken either before dialysis or on a non-dialysis day into iron-free containers, and serum was stored at-20°C until assayed. Haemoglobin concentration was measured simultaneously. Serum aspartate transaminase concentration measured by autoanalyser in all patients ranged from four to 57 IU/l; in only three patients did the concentration exceed 50 IU/l. Serum fer...

Tumour necrosis factor-alpha (TNF-alpha) was measured by enzyme-linked immunosorbent assay and eosinophil cationic protein (ECP) by radio-immunoassay to evaluate TNF-alpha in nasal allergy. There was no significant difference either between the mean concentrations of TNF-alpha in nasal secretions from the patients with perennial nasal allergy and those of normal subjects, or between the TNF-alp...

A patient is described who presented with the classical symptomatology and profound electrolyte disturbance of the Verner-Morrison syndrome due to a pancreatic apudoma secreting vasoactive intestinal polypeptide (VIP). Diagnosis was confirmed by plasma VIP as measured by a radio-immunoassay technique now available. It is suggested that the cyclical nature of the symptoms in this case was due to...

The plasma triiodothyronine (T3) and thyroxine (T4) ratios have been evaluated in kwashiorkor and diet-induced obese weaned rats. The concentrations of T3 and T4 were determined in plasma by radio-immunoassay. A significant decrease in T3 level in the order kwashiorkor < obese < control was observed. However T4 concentration was more elevated (P < 0.01) in the obese than the normal controls, wh...
