Testosterone metabolism in human bone

Acta Endocrinologica, 1980
Abstract. The conversion of [1,2,6,7-3H]testosterone2 to [3H]dihydrotestosterone has been assessed in ground spongiosa of normal and osteoporotic bone. The tissue was obtained from 23 patients, 18 women, 3 men and 2 children who were undergoing orthopedic surgery. The formation of dihydrotestosterone was demonstrated in all samples examined.

Fracture of human femoral bone

Journal of Biomechanics, 1984
The work-of-fracture of human femoral bone was determined using the technique of Tattersal and Tappin (1966). The work required to fracture a specimen in three point bending by slow crack propagation through a triangular cross-section is obtained from the load-deflection curve. The area of the resulting fracture surface is measured by macrophotographic

Human Bone Marrow Sulphydryl Levels

British Journal of Haematology, 1968
Summary The acid soluble, protein and total —SH values for 101 samples of bone marrow from hospital patients have been measured. The results have been considered in terms of age, sex, clinical status and the susceptibility of bone marrow to drugs and radiation.

Chemical composition of human bone

Archives of Oral Biology, 1983
The mineral and non-collagenous organic components of normal human femoral cortex were examined following powdering, demineralization with EDTA and digestion with bacterial collagenase. The protein, hexose, sialic acid and uronic acid contents of the matrix were determined.

Bone Resorption in Human Cholesteatomas

Annals of Otology, Rhinology & Laryngology, 1982
In vivo studies of different aspects of bone resorption in human cholesteatomas are described in the immunodeficient “nude” mice. Cholesteatoma membranes were transplanted into the middle ear cavities of the mice. After 21–28 days, growth of cholesteatoma tissue could be demonstrated in 8 of 13 animals.

Tympanometry in Human Temporal Bones

Archives of Otolaryngology - Head and Neck Surgery, 1970
Tympanometry is a technique used to assess the mobility and condition of the tympanic membrane and middle ear during variation of air pressure in the ear canal. The technique was applied to a series of 21 fresh human temporal bones, 11 of which were judged to be normal.

HIV infection in human bone

The Journal of Bone and Joint Surgery. British volume, 1992
Bone transplantation is often used for the reconstruction of defects. The best results are achieved with autogenous grafts because they induce no immunological reaction, but allogeneic grafts from bone banks are frequently used to provide an adequate volume of bone (Cookson et al 1988).

Magnesium distribution in human bone

Calcified Tissue International, 1994
The present study was undertaken to reveal the magnesium distribution in human bone. Sixty human ribs, obtained from subjects aged 10-80 years of age, were used. Transverse sections were prepared from the middle region of the human ribs. Adjacent sections were ground to a thickness of about 1000 microns. One section was used for magnesium determination

Glycosaminoglycans of human alveolar bone

Archives of Oral Biology, 1989
Bone proteoglycan was extracted and the glycosaminoglycan (GAG) components identified. Chondroitin-4-sulphate was the major GAG detected and represented 93.8% of the total GAG extracted. In addition, hyaluronic acid (1.3%), dermatan sulphate (3.1%) and heparan sulphate (1.8%) were identified as minor constituents.

Magnetic bones in human sinuses

Nature, 1983
Studies on the interaction of magnetic fields and biological organisms have centred on the influence of applied magnetic fields on the physiology and behaviour of organisms, including humans, and a search for magnetic sources within the organisms themselves.
