To elucidate compositional changes of the pubic symphysis (PS) by aging, elements of pubic symphyses (PSs) removed from 26
cadavers were determined by inductively coupled plasma atomic-emission spectrometry. It was found that the relative contents
(RCs) of calcium and phosphorus in women’s PSs were about three-and five-fold amounts as compared with those in men’s PSs,
respectively. In contrast, the RCs of sulfur, magnesium, sodium, and iron in women’s PSs were somewhat lower than those in
men’s PSs. The accumulations of calcium (Ca) and phosphorus (P) in women’s PSs occurred mainly beyond the age of 70-yr-old,
but did not occur in men’s PSs. 相似文献

To elucidate compositional changes of the articular disk (AD) of the temporomandibular joint (TMJ) by aging, elements of the
ADs resected from 18 cadavers were determined by inductively coupled plasma atomic-emission spectrometry. It was found that
calcium contents of ADs in TMJs increased progressively with aging, whereas the sulfur contents of the ADs decreased slightly
with aging. Regarding the content of phosphorus, the contents increased progressively with aging. The study revealed that
age-related changes of calcium contents in the ADs of TMJs were similar to those in women’s pubic symphyses, but not those
in intervertebral disks and menisci. 相似文献

To elucidate compositional changes of human ligaments by aging, the content of elements in anterior cruciate ligaments (ACLs)
and ligamenta capitum femorum (LCFs) was analyzed by inductively coupled plasma-atomic emission spectrometry. The subjects
consisted of 11 men and 7 women, ranging from 59 to 91 yr of age. With regard to the content of elements, the content of sulfur
and iron was significantly higher in the LCFs than in the ACLs. It was found in the ACLs that the content of sulfur decreased
gradually with aging, whereas the content of calcium, phosphorus, and magnesium increased progressively with aging. On the
other hand, it was found in the LCFs that the content of magnesium decreased gradually with aging, whereas the content of
phosphorus increased progressively with aging. The common finding that the content of phosphorus increased with aging, but
the content of iron decreased, was obtained in the ACL and LCF. Regarding sexual difference, it was found in both the ACLs
and LCFs that the content of phosphorus was higher in women’s ligaments than in men’s. 相似文献

To elucidate changes of human tendons with aging, the authors studied age-related changes of elements in human Achilles’ tendons
by inductively coupled plasma-atomic emission spectrometry. The subjects consisted of seven men and seven women, ranging in
age from 61 to 97 yr. It was found that the content of calcium increased progressively with aging in the Achilles’ tendons,
whereas the contents of phosphorus and magnesium decreased gradually with aging. The previous investigations demonstrated
that the content of calcium and phosphorus increased progressively with aging in most, but not all, human tissues, except
for the bones. In ligaments, such as the anterior cruciate ligament and the ligament of the head of the femur, which are histologically
similar to the Achilles’ tendon, it was previously found that both the contents of calcium and phosphorus increased with aging
in the ligaments. It should be noted that the content of phosphorus in the Achilles’ tendons decreased during the aging process.
In addition, it was found that there was a very high direct correlation between phosphorus and magnesium contents in the tendons,
but not between calcium and phosphorus contents. 相似文献

To elucidate compositional changes of elements in the meniscus with aging, the authors investigated the relationships among
elements in the medial meniscus by inductively coupled plasma-atomic emission spectrometry. The subjects consisted of 16 men
and 7 women, ranging in age from 65 to 93 yr. In the left medial meniscus, extremely significant correlations were found both
between calcium and phosphorus contents and between sulfur and magnesium contents, whereas significant correlations were found
between calcium and either iron or zinc contents, between phosphorus and either iron or zinc contents, and between iron and
zinc contents. On the other hand, in the right medial meniscus, there were only an extremely significant correlation between
calcium and phosphorus contents and a significant correlation between sulfur and magnesium contents. The common finding between
the left and right medial menisci was an extremely significant correlation between calcium and phosphorus contents and a significant
correlation between sulfur and magnesium contents. 相似文献

To elucidate age-related changes of mineral contents in human bones, element contents of human vertebrae and auditory ossicles
were determined by inductively coupled plasma atomic-emission spectrometry. The cervical, thoracic, and lumbar vertebrae were
removed from 12 vertebral columns. The mallei of auditory ossicle were removed from 27 cadavers.
It was found that average relative contents (RCs) of calcium and phosphorus in cervical, thoracic, and lumbar vertebrae remained
almost constant within ages ranging from 46 to 99 y. In addition, it was found that the RCs of calcium and phosphorus in men’s
and women’s mallei remained constant within ages ranging from 40 to 98 yr. These results support the view that there is no
significant agedependent change of mineral contents in human bones. 相似文献

The relative contents (RCs) of mineral elements in aortae and cerebral arteries from 23 subjects, with ages ranging between
45 and 99 yr, were analyzed by inductively coupled plasma atomic emission spectrometry. The RCs of calcium, phosphorus, and
magnesium in the aortae increased markedly after the age of 70. While the RC of sulfur in aortae decreased gradually after
that age. It was found that accumulation of calcium and phosphorus occurred primarily in the tunica media of aorta, and secondarily
in the tunica intima. Furthermore, the RCs of calcium, phosphorus, and magnesium in cerebral arteries increased markedly after
the age of 70, whereas the RC of sulfur in cerebral arteries decreased after age 70. It was found that accumulation of calcium
and phosphorus in the cerebral arteries were 30 and 60%, respectively, lower than those in the aortae with ages ranging between
45 and 99 yr. 相似文献

The purpose of this study is to investigate the relationship between meniscal degeneration and element contents. The contents
of elements (calcium, phosphorus, sulfur, and magnesium) in the menisci from 17 patients with osteoarthritis (OA) of the knee,
6 with rheumatoid arthritis (RA), and 2 who underwent the surgical operation for malignant tumors (control) were analyzed
by inductively coupled plasma-atomic emission spectrometry, and the menisci were divided into four stages (Stage 0–3) of histological
degeneration.
The calcium contents of the menisci were 0.26±0.16 in Stage 0, 0.50±0.37 in Stage 1, and 0.69±0.66 in Stage 2, respectively
(the values represent mg elements/g dry tissue). They increased with the progression of the stage. This tendency was found
in the menisci with OA, but was not clear in those with RA. The calcium content in the control group was 0.17±0.09 mg/g. There
was no significant relationship between the stage of degeneration and the contents of phosphorus, sulfur, or magnesium. The
calcium content of the meniscus might indicate the degree of meniscal degeneration. 相似文献

To examine age-related changes of human cardiac valves, mitral and tricuspid valves were analyzed by inductively coupled plasma-atomic
emission spectrometry. The subjects for mitral valves consisted of 12 men and 8 women, ranging in age from 52 to 96 yr. The
subjects for tricuspid valves consisted of 11 men and 6 women, ranging in age from 52 to 93 yr. Furthermore, 16 of the samples
of the cardiac valves were derived from the same subjects.
The contents of calcium, phosphorus, and magnesium in the mitral valves increased progressively with advancing age and reached
maximum in the 80s in regard to calcium and phosphorus and maximum in the 90s in regard to magnesium. The maximum average
amounts corresponded to about three times the average contents in the 60s. In contrast, the content of sulfur in the mitral
valves remained constant between the 50s and 90s.
Regarding tricuspid valve, the contents of calcium, phosphorus, and magnesium scarcely increased with advancing age, except
for one subject who died of chronic renal failure.
Histological observations of the mitral valves revealed that deposits of calcium were present in both the elastic fibers and
its degenerative tissues of the mitral valve.
The present study indicates that the accumulation of calcium, phosphorus, and magnesium occurs progressively in the mitral
valve with aging, but does not occur in the tricuspid valve. 相似文献

To elucidate accumulations of minerals in the human aorta and internal thoracic artery, their relative contents (RCs) of minerals
were analyzed by inductively coupled plasma atomic emission spectrometry.
Aortas from 47 men and 24 women subjects were examined. The ages of these subjects ranged from newborn to 99 yr. After the
age of 40 yr, RCs of calcium and phosphorus began to increase, and thereafter increased stepwise in the 50s and 70s. In the
70s, their accumulations were markedly increased.
Internal thoracic arteries from 16 men and 7 women subjects were examined. These subjects ranged in age from 65–93 yr. It
was found that all the RCs of calcium were low, <5.0 mg/g dry wt, and there was no age-dependent increase of calcium contents
in internal thoracic arteries. 相似文献

To examine whether the calcium accumulation in aged arteries is related to the way of walking, the mineral contents were determined
in the arteries of Japanese monkeys of quadrupedal walk by inductively coupled plasma-atomic emission spectrometry. Sixteen
Japanese monkeys consisting of 7 males and 9 females ranging in age from 2 to 33 yr were studied.
The accumulation of calcium, phosphorus, and magnesium occurred progressively in most, but not all, of the arteries with aging.
It was found that independent of the upper and lower limbs, a higher accumulation of calcium, phosphorus, and magnesium occurred
in the arteries of the proximal regions with aging, compared with the arteries of the distal regions.
In a comparison between the arteries of anatomically corresponding regions of the upper and lower limbs, the accumulation
of calcium and magnesium was 20–60% higher in the external iliac and femoral arteries of the lower limb than in the axillary
and brachial arteries of the upper limb. Regarding phosphorus, the accumulation was 20–120% higher in the external iliac and
femoral arteries than in the axillary and brachial arteries. It was known that in humans, the accumulation of calcium, phosphorus,
and magnesium was three to seven times higher in the arteries of the lower limb than in the arteries of the upper limb. It
is clear that there is a very significant difference in the accumulation of calcium and magnesium in the arteries of the lower
limbs between Japanese monkeys and humans. The present study suggests that the accumulation of calcium and magnesium in the
arteries of the lower limb with aging is affected by the way of walking. 相似文献

The relative contents (RCs) of elements in the femoral arteries as well as the thoracic aorta, coronary, basilar, and radial
arteries from 26 subjects within the age range between 55 and 92 yr old, were analyzed by inductively coupled plasma atomic
emission spectrometry.
The RCs of calcium and phosphorus in the femoral arteries started to increase before the age of 60 yr. The RCs of magnesium
increased after the age of 70 yr. However, the RCs of sulfur did not change significantly within the age range between 55
and 92 yr.
With regard to localization of the mineral accumulations in the femoral arterial wall, it was found that the accumulations
of calcium and phosphorus occurred only in the tunica media, only in the tunica intima, or in both the tunica media and the
tunica intima. The manner of accumulation of calcium and phosphorus in the femoral arterial wall was different from that in
the aortic wall.
The average RCs of calcium in the 26 specimens were the highest in the femoral artery, followed in descending order by the
thoracic aorta, coronary, basilar, and radial arteries. The average RCs of phosphorus were highest in the thoracic aorta,
followed by the coronary, femoral, basilar, and radial arteries. It is noted that the accumulation of mineral elements never
occurred uniformly in all the arteries. 相似文献

To elucidate the element content of newborn blood vessels, umbilical arteries and veins in human umbilical cords, which had
the advantage of easy sampling, were examined by ICP-AES. Umbilical cords were removed after birth. Mothers’ ages ranged from
26 to 35 yr. It was found that the content of sulfur was the highest in both umbilical arteries and veins, being higher than
the content of calcium and phosphorus. With respect of the content of sulfur, calcium, and magnesium, there were significant
differences between the arteries and veins. 相似文献

To establish a difference of the relative contents (RCs) of elements among the cervical, thoracic, and lumbar intervertebral
disks and its age-related change, the intervertebral disks between the axis and the sacrum, which were resected from the nine
cadavers who died at 53 to 99 yr old, were analyzed by inductively coupled atomic plasma emission spectrometry. It was found
that both the RCs of calcium and phosphorus were high in the cervical disks, especially the highest in the disk between the
6th and 7th cervical vertebrae, and lower in the order of the cervical, thoracic, and lumbar intervertebral disks. In regard
to the RCs of sulfur and magnesium, there were no significant differences among the cervical, thoracic, and lumbar intervertebral
disks. In addition, it was found that both the RCs of calcium and phosphorus in the cervical intervertebral disks started
to increase in the sixth decade of life, became the highest in the eighth decade of life, and then decreased. 相似文献

To analyze the accumulation of elements in the rami of the coronary arteries, the authors determined element contents in both
the coronary arteries and their rami of the Thai by inductively coupled plasma-atomic emission spectrometry. The subjects
consisted of 13 men and 6 women, ranging in age from 34 to 83 yr. It was found that a higher accumulation of calcium and phosphorus
occurred in the proximal sites of coronary arteries such as the anterior descending, right coronary, left coronary, and circumflex
arteries than the distal sites such as the diagonal, lateral, conus, acute marginal, and posterior descending arteries. The
accumulation of calcium and phosphorus in the anterior descending and right coronary arteries of the Thai increased remarkably
in the fifties, thereafter decreased, and increased again in the eighties. It should be noted that a very high accumulation
of calcium and phosphorus in the coronary arteries occurred in the fifties. In regard to relationships among the average contents
of elements in the coronary arteries and their rami, it was found that there were very significant direct correlations between
calcium and phosphorus contents, between calcium and magnesium contents, and between phosphorus and magnesium contents. These
results suggested that as calcium and phosphorus increased in the coronary arteries and their rami, magnesium increased simultaneously
in all of the coronary arteries and their rami. 相似文献

To elucidate age-related changes of mineral contents in human veins, the relative contents (RCs) of elements in the human
internal jugular veins, superior and inferior venae cavae, and femoral veins from 27 subjects ranging from 40 to 98 yr old
were analyzed by inductively coupled plasma atomic emission spectrometry.
The average RCs of calcium in the 27 specimens were the highest in the internal jugular vein, followed in descending order
by the superior vena cava, femoral vein, and inferior vena cava.
The RCs of calcium and phosphorus in the internal jugular veins started to increase after the age of 50 yr, became the highest
in subjects in their 60s and thereafter decreased gradually. It is noted that such accumulations of minerals, similar to the
internal jugular vein, were also found in the veins, such as the superior and inferior venae cavae, and femoral vein. Accumulation
of minerals in the veins is different from that of arteries, which increase progressively by aging, but do not decrease. 相似文献

To elucidate compositional changes of the uterine tube by aging, the authors studied age-related changes of elements in human uterine tubes by inductively coupled plasma-atomic emission spectrometry. The uterine tubes were resected postmortem or surgically removed from patients with uterine myoma. It was found that the contents of calcium and magnesium increased progressively with aging in uterine tubes, whereas the contents of phosphorus and iron decreased gradually with aging. The sulfur content of uterine tubes remained constant and independent of aging. Regarding relationships between elements, significant relationships were found between calcium and magnesium contents, between phosphorus and iron contents, between phosphorus and sulfur contents, and between phosphorus and sodium contents in human uterine tubes. 相似文献

To elucidate changes of the ureter with aging, the authors investigated age-related changes of element contents in human ureters.
The subjects consisted of seven men and seven women, ranging in age from 61 to 97 yr. The contents of calcium, sulfur, and
iron in the ureters increased progressively with aging, whereas the contents of phosphorus and magnesium did not increase
with aging. Significant relationships were found both between calcium and sulfur contents and between calcium and iron contents
in the ureters, but not between calcium and either phosphorus or magnesium contents. It was noteworthy that a significant
relationship was also found between sulfur and iron contents in the ureters. It remains uncertain whether calcium forms a
compound with sulfur or iron in aged human ureters or not. 相似文献

To elucidate compositional changes of the elastic cartilage with aging, the authors investigated age-related changes of elements
in the epiglottal cartilages by inductively coupled plasma-atomic emission spectrometry. After the ordinary dissection by
medical students at Chiang Mai University was finished, the epiglottises were resected from the subjects. The epiglottal cartilages
were isolated and the element contents were determined. The subjects consisted of 11 men and 14 women, ranging in age from
39 to 92 yr old. It was found that although the extent of accumulation of calcium and phosphorus was slight, calcium and phosphorus
increased progressively in the epiglottal cartilages with aging. In contrast, sulfur, magnesium, zinc, iron and sodium did
not change significantly in them. Regarding the relationships among elements, it was found that there were significant correlations
among calcium, phosphorus, magnesium, and sodium in the epiglottal cartilages, with one exception between calcium and sodium
contents. In comparison between men and women, no significant differences were found in the predominant elements such as calcium,
sulfur, and phosphorus in the epiglottal cartilages. 相似文献

“Cold-stunning” of sea turtles has been reported as a naturally occurring stressor for many years; however, the physiologic
status of cold-stunned turtles has only been partially described. This study investigated initial and convalescent venous
blood gas, acid-base, and critical plasma biochemical data for 26 naturally cold-stunned Kemp’s ridley sea turtles (Lepidochelys
kempii) from Cape Cod, MA, USA. Samples were analyzed for pH, pCO2, pO2, bicarbonate, plasma osmolality, sodium, potassium, chloride, ionized calcium, ionized magnesium, glucose, lactate, and blood
urea nitrogen using a clinical point-of-care analyzer. Data were corrected for the patient’s body temperature using both species-specific
and more general correction methods. In general, venous blood gas, acid-base, and plasma biochemical data obtained for surviving
cold-stunned Kemp’s ridley sea turtles were consistent with previously documented data for sea turtles exposed to a wide range
of temperatures and physiologic stressors. Data indicated that turtles were initially affected by metabolic and respiratory
acidosis. Initial pH-corrected ionized calcium concentrations were lower than convalescent concentrations, and initial pH-corrected
ionized magnesium concentrations were higher than convalescent concentrations. 相似文献
