Abstract Anomeric configuration of oligosaccharides usually is established by specific glycosidases. For this purpose detergents achieving water solubility of primarily insoluble glycosphingolipids as substrates have been replaced by delipidated hum an serum high density lipoproteins. The new method, tested by several well characterized glycosphingolipids and glycosidases, finally was applied to the evaluation of anomeric structures of two blood-group B active glycosphingolipids [ceramide hexa-saccharide (B-I) and ceramide octasaccharide (B -II)] from hum an erythrocyte membranes. In both B-I and B-II, α-glycosidic linkage was dem onstrated for the term inal galactose and fucose residues. β-glycosidic linkage has been evaluated for backbone saccharides. Together with the results pre­ viously obtained by composition analysis, linkage analysis and sequence analysis the following complete structure can be established:B -I: Galα1 → 3Gal (2 ← 1αFuc)β1 → 4GlcNAcβ1 → 3Galβ1 → 4Glcβ1 → 1Cer;B-II: Galα1 → 3Gal (2 ← 1αFuc)β1 → 4GlcNAcβ1 → 3Galβ1 → 4GlcNAcβ1 → 3Galβ1 → 4Glcβ1 → 1Cer.

AbstractThe influence of pre-slaughter nutrition on the potency of foetal serum in cell culture was studied. Ewes carrying late-gestation foetuses (120-day gestation) were either fasted for 66 h (F), fasted for 66 h but drenched with Ketol, a propylene glycol preparation, (5 × 120 ml doses; FK), given food ad libitum (A), or given food ad libitum and drenched with Ketol (5 × 120 ml doses; AK). Following slaughter foetal blood was collected for the determination of potency in cell culture using industry-standard cell culture bioassays: cloning efficiency, plating efficiency and a 96 h cell proliferation assay. Foetal serum insulin-like growth factor (IGF) concentrations were also measured. Pre-slaughter fasting or drenching with Ketol had no effect on the potency of foetal serum in any of the cell culture bioassays. Fasting significantly lowered foetal plasma IGF-1 levels (F < 0·01). Foetal IGF-2 levels were unaffected by fasting or drenching with Ketol.

Meta Analyses

AB0 blood group antigens were discovered over a century ago; however, it is still important to study their role in development of various pathological conditions. Today it is known that antigenic determinants of this blood group are present not only on erythrocyte membrane but also on other cells and tissues: platelets, gastrointestinal epithelium and salivary glands, respiratory system cells. In the last decade, a large number of studies have appeared to reveal the relationship between a specific disease and blood group type, meta-analyses have been published. Previously, the authors have studied the metabolic status, cell composition and coagulation profile of clinically healthy individuals for more than on 180,000 donations, that allowed to identify group-specific features for each blood group. This review presents generalized data on the association of such pathological conditions as coronary heart disease, thromboembolic complications, tumors of various localizations, inflammatory and destructive oral diseases, psychiatric and some infectious diseases with the presence or absence of antigenic determinants A and B. Carriers of blood group 0 (I) are generally more resistant to diseases, with the exception of H.pylori-associated gastrointestinal diseases. Carriers of «antigenic» blood groups A (II), B (III), AB (IV) are more susceptible to development of infectious, cardiovascular and cancer diseases. The presented data demonstrate clinical significance of the definition of group typing not only for selection of blood and its components during transfusion and transplantation, but also for diagnostics, determination of risk group and tactics for treatment patients with different nosologies.
