Biochemical characteristics of Ehlers-Danlos syndrome type VI in a family with one affected infant.

The parents of a child with the clinical symptoms of Ehlers-Danlos syndrome type VI were identified as third-degree cousins. Biochemical analysis of the dermis of the patient revealed a complete lack of hydroxylysine in the dermal collagen. The dermis of both parents contained only half the amount of hydroxylysine found in healthy individuals. Hydroxylation of prolyl residues was normal in the skin of the patient and his parents. Investigation of the collagen synthesized by fibroblasts derived from the skin of the patient showed a normal proportion of type I and type III collagen. However, while hydroxylation of prolyl residues was normal in type I and type III collagen, hydroxylation of lysyl residues was markedly lower than normal in both type I and type III collagen.

Comparison of 9 methods for the determination of cholesterol.

Seven enzymatic procedures for the determination of cholesterol in serum were compared with the Liebermann-Burchard- and a gas-chromatographic method. Using a decision matrix all methods could be ranked according to reliability and practicability . With the exception of the cholesterol oxidase-coupled Kageyama principle and the Liebermann-Burchard procedure, all the other methods showed similar reliability.

Studies on the methodology and evaluation of the lymphocyte transformation microtest.

Optimum experimental conditions for the lymphocyte transformation microtest in healthy persons are described. The dependence of PHA stimulation on duration of culture, additions of serum and PHA concentration is investigated. A function of normal distribution pattern can be set up by determining the lymphocyte stimulability with four different PHA concentrations in the optimal stimulation range. With this function, the area under the curve, steepness, position and height of the maximum can be calculated. These parameters should serve for better interpretation of cellular immunity.

HL-A antigens in carcinoma of the breast, ovarium, cervix and endometrium: possible association of haplotype HL-A10-W18 with carcinoma of the breast.

24 HL-A antigens were determined in a total of 163 Caucasien cancer patients (60 breast cancers, 64 cancers of the cervix uteri, 19 cancers of the endometrium and 20 cancers of the ovary). The comparison of the antigen frequencies with the analogous values from 1000 healthy controls yielded no outstandingly significant deviations for cancer of the cervix, endometrium and ovary. In breast cancer patients, however, there might be an association with the antigens HL-A10 and W18 or the haplotype HL-A10-W18, as indicated by the results of a combined evaluation of our data together with the results of four different HL-A studies in breast cancer patients.
