    Photoluminescence characterization of InP surface reactive ion etched by a gas mixture of ethane and hydrogen (1991)

    Notes: InP crystals were etched by reactive ion etching (RIE) with gas mixture of ethane and hydrogen (C2H6/H2), and etching damages were characterized by photoluminescence (PL) measurements of near-edge and defect-related emissions. Near-edge PL emission intensities after RIE were equal to or larger than those before RIE, except for the samples etched for 50 min. The damage introduced by RIE was restricted to the very-near-surface region which can be removed by HF treatment. The peak energy of defect-related 1.1-eV deep emission bands shifted toward the lower-energy side for the crystals with etching damages at the surface. The peak shift is attributable to the increase of defect complexes such as P-vacancy–P-interstitial or P-vacancy–In-vacancy.

    Urinary Excretion of Type I Collagen Degradation Products in Healthy Women and Osteoporotic Patients with Vertebral and Hip Fractures (1998)

    Notes: Abstract. We have evaluated both the effect of normal aging and menopause on urinary CrossLaps™ (u-CTx) excretion and the bone resorption status by u-CTx in patients with vertebral fracture and hip fracture. In 246 healthy women, 76 patients with vertebral fracture, and 63 patients with hip fracture, u-CTx excretion was measured by ELISA. The age-related changes of u-CTx in healthy females reflected the marked increase of bone resorption associated with modeling at childhood. The values in the subgroups of postmenopausal women 1–3 years since menopause and ≤10 years since menopause were significantly higher than those in the subgroups of premenopausal adult women. The values in the vertebral fracture group were significantly higher than those in the premenopause group, but not those in the postmenopause groups. The values in the hip fracture group were significantly higher than those in the other groups. Of the 70 postmenopausal subjects aged 45–64 years, 43% had u-CTx values more than 2 SD above premenopausal mean. The corresponding values in the patients with vertebral fracture and those with hip fracture were 58% and 64%, respectively. This marker reflects well the increase of bone resorption associated with bone modeling at childhood and with high bone turnover after menopause. The excretions in the patients with hip fracture were much higher than those in the age-matched subjects and also higher than those in the patients with vertebral fracture. These findings indicate that the abnormality of bone resorption in the patients with hip fracture is more severe than in the patients with vertebral fracture.

    Notes: Abstract. Urinary deoxypyridinoline, serum osteocalcin (OC), and ultrasound (US) measurements were investigated in a premenopausal group and a postmenopausal group. In previous studies we reported the relation between each biochemical marker and each US parameter by simple regression analysis. However, in this study, multiple regression analysis of the US parameter, not only by biochemical markers but also by age and body mass index (BMI), were done to determine what fraction of the variation in the respective US values can be accounted for by these factors. Multiple regression analysis showed that age and serum OC were significant determinants for stiffness index, serum OC and BMI were significant determinants for speed of sound, age was a significant determinant for broadband ultrasound attenuation, although each US parameter can be explained by factors of approximately only 26–33%.

    The effect of menopause on biochemical markers and ultrasound densitometry in healthy females (1994)

    Notes: Abstract Urinary pyridinoline (pyr) and deoxypyridinoline (dpyr) are new markers for bone resorption, and serum osteocalcin reportedly indicates osteoblastic activity. Recently, a new ultrasound bone densitometer instrument has been developed that measures ultrasonic properties of the os calcis, namely, the speed of sound (SOS), broadband ultrasound attenuation (BUA), and stiffness index. The effects of menopause on biochemical markers and ultrasound densitometry were investigated in 40 healthy females, 36–39 years, with regular menstruation, and in 117 healthy perimenopausal females, 47–57 years, who were divided into a premenopausal group and a postmenopausal group. Significantly elevated values of pyr, dpyr, and serum osteocalcin were found for the postmenopausal group as a whole compared with the premenopausal group. We examined postmenopausal groups 48–57 years of age stratified into 2-year intervals (within 2 years of the menopause, 2–4 years postmenopause and 4–6 years postmenopause). Elevated values of urinary pyr, dpyr, and serum osteocalcin were evident even in the first 2 years postmenopause compared with the premenopausal group, and these higher values were exhibited until 6 years after menopause. We found a significant decrease in SOS, BUA, and stiffness index of the postmenopausal group as a whole, compared with those of the premenopausal group. SOS, BUA, and stiffness index of the group within 2 years of menopause significantly decreased compared with those of the premenopausal group. The Z-scores of the increase in biochemical markers and the decrease in stiffness index in the postmenopausal group were approximately 0.7–1.3 compared with the premenopausal group. The results suggest that these biochemical markers and ultrasound densitometry are potentially sensitive parameters of postmenopausal bone change.

    Notes: Abstract. The aim of this study was to investigate bone mineral density (BMD) and bone turnover in patients with primary knee osteoarthritis (KOA) and to compare them with generalized OA (GOA) and nonGOA patients. A total of 88 postmenopausal primary KOA patients were studied. OA was graded by using knee radiographs. BMD of the lumber spine, femur, and radius, and biochemical markers of bone turnover, pyridinoline (Pyr), deoxypyridinoline (Dpyr), CTx, and osteocalcin were compared among each grade. BMD was also compared with 88 normal controls who were age and weight-matched. In 88 KOA patients, 56 were divided into 28 GOA and 28 non-GOA groups by grading hand radiographs. BMD and biochemical markers were compared between GOA and non-GOA. KOA patients had higher BMD at several skeletal sites compared with age- and weight-matched normals. A significant difference of BMD between each grade was observed between grades 0–1 and 3 (0.774 ± 0.143 versus 0.940 ± 0.185 g/cm2, P 〈 0.001), grades 2 and 3 (0.781 ± 0.125 versus 0.940 ± 0.185 g/cm2, P 〈 0.01) in the spine, and between grades 0–1 and 3 (0.505 ± 0.100 versus 0.564 ± 0.127 g/cm2, P 〈 0.05) in the trochanter. A significant difference of biochemical bone markers was observed between grades 0–1 and 3 (P 〈 0.05) and between grades 2 and 3 (P 〈 0.05) in Pyr and grades 0–1 and 3 (P 〈 0.05) and between grades 1 and 4 (P 〈 0.05) in Dpyr, but not in osteocalcin and CTx. GOA patients had higher BMD of the spine (0.902 ± 0.175 versus 0.747 ± 0.138 g/cm2, P 〈 0.01), trochanter (0.535 ± 0.107 versus 0.480 ± 0.107 g/cm2, P 〈 0.05), and one-third of the radius (0.526 ± 0.068 versus 0.472 ± 0.089 g/cm2, P 〈 0.05) and had significantly higher biochemical markers in Pyr and Dpyr than non-GOA patients. It is concluded that KOA patients had higher BMD at several skeletal sites. Biochemical bone markers were influenced by some degree of cartilage damage in OA patients. This tendency was stronger in GOA patients than in non-GOA patients.
