摘要:

SummaryTotal lipids extracted from J‐positive cattle serum, erythrocytes or spleen exhibit J blood‐group activity. The J subsance is concentrated in a lipid fraction obtained by column chromatography. Following mild alkaline hydrolysis or reduction with complex hydrides (LiAlH4, LiBH4), the J activity remains detectable in this lipid fraction even though all acyl ester groups have been destroyed as revealed by ester group determination. This disagrees with the suggestion that fatty acyl esters are essential for J activity. This was confirmed by experiments with a water‐soluble J‐active product prepared by ozone treatment of glycosphingolipids from bovine spleen. The results of these experiments are in favour of a glycosphingolipid containing an unusually lang oligosaccharide chain. Furthermore, it appears that the terminal moiety of the J determinant is not necessarily an N‐acetyl galactos‐amine unit as suggested

摘要:

SummaryThree individual variants of acid phosphatase in chicken leucocytes were found by means of starch gel electrophoresis. The phenotype in leucocytes showed the same appearance as polymorphic forms of liver acid phosphatase in the same bird. The study of the Hardy‐Weinberg distribution of the phenotypes of acid phosphatase in leucocytes also indicated that they are controlled by the same pair of codominant autosomal alleles as the phenotypes in the liver.Acid phosphatase is polymorphic in all six strains of chickens studie

摘要:

SummaryGenetic variants of serum alkaline phosphatase were studied by the method of starch gel electrophoresis in the Zlotnicka Pstra breed of pigs. Two regions of alkaline phosphatase migration were observed. A single fraction in region I and four different phenotypes: AB, B, BC and BD in region II, were found. For AB, B and BC phenotypes the genetic control by three allelesAkpA, AkpBandAkpCin suggested. The observed segregation ratios in some cases deviated significantly from the expected ones.

摘要:

SummaryThe ontogeny of haemolytic complement in rabbit serum and the genetic differences of the activity in five strains of adult rabbits were investigated by single radial haemolysis in gel and a microtiter method with purified complement components and the appropriate haemolytic intermediate cells.The haemolytic complement activity was found as early as the 15th day of foetal life, and increased with age reaching approximately adult level by the 120th day of life. Marked strain differences in both total haemolytic activity and C3 levels of adult rabbit sera were observed. The repeatability of haemolytic activity for an individual serum taken at different times was higher than that for C3 levels and no significant correlation between haemolytic activity and C3 level was observed. An inherited complement deficiency, due to the lack of C6, was found in a strain of Angora rabbits. The genetic studies confirmed that this complement defect was transmitted as an autosomal recessive trait.

摘要:

SummaryAn investigation on the genetic relationships between 12 horse and pony breeds was performed, using blood protein variants as genetic markers. The relationships were established by the use of 5 different numerical taxonomic methods, 4 of which yielded very similar results. The relationships as estimated were evaluated on the basis of the breeds' historical development.

摘要:

SummaryThree biochemical gene markers test the hypothesis that the European hake,Merluccius merluccius(L.), along the west European continental shelf are one race. The three polymorphic loci were serum transferrin (Tf), eye vitreous fluid butyric esterase (Es) and liver superoxide dismutase (Sod). Five transferrin alleles, three esterase alleles and two superoxide dismutase alleles were identified. Heterogeneity tests on genotype frequency distribution for twelve areas ranging from Norway to Biscay revealed no significant variation. The results using these genetic tags are consistent with the unit race hypothesis for hake throughout the sea areas sampled.

摘要:

SummaryCattle, red cell antigens as determined by a selected battery of 37 reagents characterizing genes at 10 major loci in 101 Zebu, 63 Ndama and 78 Muturu from Nigeria, have been compared with corresponding red cell antigens of a total of 257Bos tauruscattle in Norway, the Netherlands, France, Spain, Hungary and USA. The Zebu cattle, represented by the three subtypes Gudali, Red Bororo and Shuwa Arab, showed the highest number of red cell factors. Ndama and Muturu cattle had a significantly lower number of blood factors than the Zebu cattle. The lowest number of blood factors were found in EuropeanBos taurusbreeds.
