The Rho Variant-Du

A simplified test for the D^u factor employing a reagent containing 25 per cent serum albumin, the "stick" technic to introduce cells and forceful cen-trifugation has been given an extensive trial in a routine blood bank operation. A routine preliminary test with anti-D gave 5,051 negative reactions among 26,753 bloods tested. The D^u tube test was then performed on the former with an anti-CDE reagent in parallel with the indirect antiglobulin test done with anti-D. All bloods positive by one or both tests were tested further for D antigens by an anti-D elution technic; they were also tested for Rh-Hr factors.
Among the 126 bloods positive by elution for the D^ufactor, 122 and 126 were positive respectively by the antiglobulin and the D^u tube tests. The two tests were in agreement on all eight of the type ccD^uee bloods found in the study. The D^utube test, as done with anti-CDE, gave no false negative reactions. It is, thus, concluded that bloods which are negative with this test will be type ccddee and can be labeled "Rh negative tested for D^u. Serological factors which might account for sensitivity of the D^u tube test's being the equal of the antiglobulin test are considered, as are the probabilities of the existence of D variants so weak that they could not be detected by either test.

Comparative Absorption of Ferri-Haemoglobin-59Fe/Ferro-Haemoglobin-59Fe and 59Fe3+/59Fe2+ in Humans with Normal and Depleted Iron Stores*

Abstract. The intestinal ⁵⁹Fe absorption from ferri- and ferro-haemogIobin-⁵⁹Fe and ⁵⁹Fe³⁺ and ⁵⁹Fe⁺ was calculated from whole body-⁵⁹Fe-retention measurements in subjects with normal and depleted iron stores. A ferri-haemoglobin-⁵⁹Fe/ferro-haemoglobin-⁵⁹Fe absorption ratio of 1.03 ±0.11 was observed for the absorption of ferri-haemoglobin-⁵⁹Fe (8.6± 0.77%) and ferro-haemogIobin-⁵⁹Fe (8.7±0.94%) in persons with normal iron stores. Depletion of iron stores caused a slight but significant higher rise of ferri-haemoglobin-⁵⁹Fe absorption (22 ± 1.7%) than the increase of ferro-haemoglobin-⁵⁹Fe absorption (18 ±0.9%) so that the absorption ratio was 1.24±0.073.—This remarkable iron valence independence of haemoglobin iron absorption is in considerable contrast to the well-established valence dependence of inorganic iron absorption which favours ferrous iron absorption especially with rising iron doses. The ⁵⁹Fe³⁺/⁵⁹Fe²⁺ absorption ratio for a diagnostic 0.56 mg Fe dose increased from 0.43 in subjects with normal iron stores to 0.74 in persons with depleted iron stores, whereas this absorption ratio was augmented only from 0.21 to 0.28 for the therapeutic 50 mg Fe-dose.—The different influence of iron valence on iron absorption from inorganic and haemoglobin iron supports other evidence for the existence of two separate mechanisms for ferrous iron and haem iron absorption in humans.     

Erythrocyte Li+/Na+ and Na+/H+ exchange, cardiac anatomy and function in insulin-dependent diabetics

It has been proposed that an increased activity of cell membrane Na+/H+ exchange, mirrored by increased erythrocyte Li+/Na+ exchange, may facilitate cell hypertrophy and hyperplasia. Patients with insulin-dependent diabetes mellitus may develop a specific cardiomyopathy with systolic and diastolic abnormalities and increased thickness of the left ventricle. Therefore, we have investigated the relationships between erythrocyte Li+/Na+ and Na+/H+ exchange and echocardiographic parameters in 31 male insulin-dependent diabetics (aged 17-68), in good metabolic control. Three had untreated mild hypertension. In all patients the urinary albumin excretion rate was less than 200 micrograms min-1. Ten patients had a Li+/Na+ countertransport higher than 0.37 mmol l-1 cell h-1, the upper normal limit for our laboratory (0.49 +/- 0.10, mean +/- SD). In comparison with the patients with normal countertransport, they had increased interventricular septum thickness and relative wall thickness (h/r). End diastolic volume and cardiac index were reduced while blood pressure and urinary albumin excretion rate were similar. In the whole study group, interventricular septum thickness was significantly correlated to Li+/Na+ exchange (r = 0.61, P less than 0.001) and Na+/H+ exchange (r = 0.35, P less than 0.05), independently of the effect of age and blood pressure. Posterior wall thickness was correlated to Li+/Na+ exchange (r = 0.38, P less than 0.05) and h/r to Li+/Na+ exchange (r = 0.41, P less than 0.05) and to Na+/H+ exchange (r = 0.44, P less than 0.05). Li+/Na+ exchange was negatively correlated to cardiac index (r = -0.37, P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)     

Further Observations on the Blood Factors RhA, RhB, RhC and RhD

The findings in 18 cases of individuals with Rh_o-positive blood who had antibodies in their serum resembling anti-Rh_o in specificity are briefly summarized.
