Calcium,magnesium, and phosphorus content of hair from two populations of rhesus monkeys

The use of hair for the assessment of human mineral nutritional status is controversial, yet has potential because of the ease of collection and storage, and the high concentration of minerals in hair. This study generated baseline values for hair macromineral content in the most commonly used primate model for human nutrition and disease, the rhesus monkey. Hair digests from monkeys in Maryland (n=98) and Puerto Rico (n=208) were analyzed by inductively coupled plasma atomic emission spectrometry (ICP-AES). Significant differences existed between the two populations for hair calcium (Ca), magnesium (Mg), and phosphorus (P) (P<0.01,P<0.001,P<0.02). Male hair had higher concentrations of Mg in specimens from the Puerto Rican population (P<0.001), whereas hair phosphorus was higher in female hair (P<0.02). There were no significant differences attributable to pregnancy status. Differences in hair content attributable to categorical age were found for Ca and Mg (P<0.001,P<0.01). Significant location differences paralleled dietary differences. These values therefore can be considered reference ranges for hair Ca, Mg, and P for free-ranging and caged rhesus monkeys. Preliminary reports of portions of these data were presented at the 69th Annual Meeting of the Federation of American Societies for Experimental Biology, April 1982, New Orleans, LA (B. M. Marriott, J. C. Smith, R. Jacobs, A. O. Jones, M. J. Kessler, and R. Rawlins,Fed. Proc. 41:770 [1982]) and in a symposium at the 6th Annual Meeting of the American Society of Primatologists, 1983, East Lansing, MI (B. Marriott, J. C. Smith, R. Jacobs, A. O. Lee Jones, R. Rawlins, and M. J. Kessler,Am. J. Primatol. 4(3):157 [1983]; B. Marriott, J. C. Smith, Jr., R. M. Jacobs, A. O. Lee Jones, R. Rawlins, and M. J. Kessler, inThe Cayo Santiago Macaques, R. Rawlins and M. J. Kessler, eds., SUNY Press, Albany, NY, pp. 219–231 [1986]).     

Brief communication: linear enamel hypoplasia and the shift from irregular to regular provisioning in Cayo Santiago rhesus monkeys (Macaca mulatta)

This study investigates changes in the prevalence of linear enamel hypoplasia (LEH) before and after the shift from irregular to regular provisioning in the Cayo Santiago rhesus monkey population. Prior to 1956, monkeys on this island colony did not receive consistent provisions, and were reported to be in poor health (Rawlins and Kessler [1986] The Cayo Santiago Macaques; Albany: State University of New York Press). A regular provisioning program, instituted in August 1956, resulted in the improved health of individuals and the growth of the population (Rawlins and Kessler [1986] The Cayo Santiago Macaques; Albany: State University of New York Press). LEH, a developmental defect of enamel, is a sensitive indicator of systemic physiological stress (Goodman and Rose [1990] Yrbk. Phys. Anthropol. 33:59-110). It was therefore hypothesized that the prevalence of LEH would be higher in monkeys who were irregularly provisioned than in monkeys who experienced regular provisioning. To test this hypothesis, teeth were examined for LEH in a sample of 181 female rhesus monkeys. The results support the hypothesis: the mean number of defects was statistically significantly higher in the preprovisioned group than it was in the postprovisioned one. When LEH prevalence was assessed using only defects occurring on antimeric pairs, the preprovisioned group again had a higher prevalence than the postprovisioned one, although the difference was not statistically significant, most likely because of the reduced sample size. The results of this study indicate that changes in LEH prevalence, at least in this population of rhesus monkeys, are associated with changes in nutritional status.

Effects of different proteins on the metabolism of Zn, Cu, Fe, and Mn in rats

Many factors are known to influence trace element metabolism and one of them is dietary protein. The present study examines the effects of casein, soybean protein, and peanut protein on the metabolism of the Zn, Cu, Fe, and Mn in growing rats. The results showed that Zn, Fe, and Mn excretions in the feces of peanut protein-fed rats (PPERs) were similar to that of casein-fed rats (CPFRs) (p>0.05), whereas all of the Zn, Cu, Fe, and Mn excretions in the urine of PPFRs were significantly higher than that of CPFRs (p<0.05), but its apparent absorption rate (AAR) of Cu, Fe and its apparent retention rate (ARR) of Cu were all higher than that of CPFRs (p<0.05). Hepatic Zn content of soybean protein-fed rats (SPFRs) was higher than that of CPFRs and PPFRs (p<0.05 respectively) and serum, renal, and femoral Cu contents of SPFRs were significantly lower; however, hepatic Cu, and renal Mn contents were significantly higher than that of CPFRs (p<0.05, respectively); The hepatic Fe content of SPFRs was significantly higher than that of CPFRs and PPFRs (p<0.01, respectively). To sum up, compared to casein, soybean protein might be a good dietary source to make up for Zn and Fe deficiency, and also peanut protein to make up for Cu and Fe deficiency.     

Influence of age, sex, and sexual activity on trace element levels and antioxidant enzyme activities in field mice (Apodemus sylvaticus and Mus spretus)

The influence of age, gender and sexual activity on both hepatic levels of some trace elements (Fe, Cu, Zn, Mn, Se) and the activities of glutathione-S-transferase (GST) and superoxide dismutase (SOD) was investigated in Wood mice (Apodemus sylvaticus) and Algerian mice (Mus spretus). Animals were taken from a riverside community of an unpolluted area of central Portugal. Adult A. sylvaticus presented the highest hepatic mean concentrations of Cu and Mn, whereas adult M. spretus had the highest Fe concentration in the liver. Moreover, an influence of age on the contents of Fe, Zn, and Mn has been observed in A. sylvaticus, whereas in M. spretus an influence of gender and sexual activity was only detected on Zn levels. In contrast, enzyme activities were not influenced by the studied variables, despite a tendency for an increase in SOD activity in sexually active M. spretus. GST activity was species dependent, whereas SOD activity was similar between species. These findings were analyzed regarding the relationship of both essential trace elements and the two antioxidant enzymes with physiological and metabolic pathways related to life cycles in the two species of mice. Results enhanced the understanding of A. sylvaticus and M. spretus as biological models, allowing their future use as bioindicators of environmental toxicity.     

九寨沟自然保护区川金丝猴的分布及种群数量

2014年2月至5月,对四川省九寨沟自然保护区野生川金丝猴的种群分布、数量及其社会结构进行调查,初步探讨该种群与其他种群在外部形态和社会结构方面的差异性。采用"V"型路线法调查,发现九寨沟保护区共有川金丝猴4群。然后结合长时间的持续跟踪观察,证实家庭单元19个,全雄群3个,能区分不同个体296只。OMU大小平均为12.7只,其中OMU内的成年个体占38%,青少年个体占53%,幼仔占9%。成年与青少年比例为1∶1.39,成年雌雄的比例为3.84∶1。与秦岭种群的外部形态相比,该种群的成年雄性更为壮大,毛发弯曲程度明显;成年雌性毛发略显灰黑色,金黄色暗淡,大部分个体嘴角长有很小的肉瘤;青少年个体毛色泛白。亦发现九寨沟种群倾向于选择海拔偏高(2400—3550 m)的针叶林带活动。     

Influence of dietary lipids on agonistic and affiliative behavior in Macaca fascicularis

The current study evaluates the hypothesis, derived from previous investigations, that alterations in dietary fat and cholesterol influence the social behavior of monkeys. Subjects were 62 adult male, cynomolgus macaques (Macaca fascicularis) assigned originally to an investigation of atherosclerosis regression. This study thus involves a secondary analysis of data derived from an investigation conducted for another purpose. Animals were housed for 14 months' in social groups of five individuals each and initially fed a diet very high in saturated fat and cholesterol to induce coronary artery atherosclerosis. Monkeys were then exposed for 28 months to one of three conditions; (1) a moderately high-fat, high-cholesterol diet and an unstable social environment (in which monkeys were switched among groups monthly); (2) a low-fat, low-cholesterol diet and an unstable social environment; and (3) a low-fat, low-cholesterol diet and a stable social environment. A comparison of animals living in unstable groups revealed that those consuming the low-fat diet exhibited more overt aggression (P < 0.001) and overt submission (P < 0.01) than did monkeys eating the high-fat diet. A second comparison involved only those animals living in stable social units. These monkeys, while consuming the low-fat diet, engaged in more aggression and submission (P_s < 0.05), spent less time in passive body contact or within touching distance (P_s < 0.001), and spent more time alone (P < 0.001) than they had initially while consuming a very high-fat diet. The current investigation is the first on this topic to include measures of social behavior in animals both before and after a reduction in dietary fat. The findings that such a reduction is associated with increased agonism and decreased affiliation may help explain the epidemiologic association in human beings between low or reduced plasma cholesterol concentrations and a high incidence of violence-related mortality. More generally, the data are consistent with the hypothesis that there is a negative feedback adaptation providing for appropriate changes in behavior in response to periodic dietary privation. © 1996 Wiley-Liss, Inc.     

三种苦苣苔对石灰土和红壤的适应性分析

为探讨苦苣苔科植物对其岩溶生境的适应性,该研究选取黄花牛耳朵(Primulina lutea)、紫花报春苣苔(Pri.purpurea)和桂林蛛毛苣苔(Paraboea guilinensis)三种苦苣苔科植物,将其栽种在石灰土及红壤两种不同类型的土壤中,观测记录其生长性状并对其叶片元素含量进行测定和比较。植株采集过程中,同时采集自然生境中三种苦苣苔科植物叶片及取样植物基部土壤,并对叶片及土壤元素的含量进行测定,作为今后苗圃试验的参照。结果表明:三种苦苣苔科植物在两种土壤上的生长状况及适应性具有差异,其在石灰土上生长良好,在红壤上生长较差;在两种不同土壤中,除N外,桂林蛛毛苣苔的叶片其他元素(P、K、Mn、Mg、Ca、Zn、Cu)差异极显著(P0.01);除P外,紫花报春苣苔的叶片其他元素(N、K、Mn、Mg、Ca、Zn、Cu)差异极显著(P0.01);除N、Cu、Ca外,黄花牛耳朵的叶片元素(P、K、Mn、Mg、Zn)差异极显著(P0.01);三种植物的叶片元素比值,除少数值没有差异外,大部分指标差异都极显著;对叶片元素与栽培土壤元素的相关性分析,发现植物叶片Mn元素与土壤中N、Ca、Mg、Zn、Mn、有机质含量等呈正相关,土壤P元素与叶片中N、P元素呈正相关,而与叶片中Zn元素呈负相关关系。在其他栽培条件一致的条件下,土壤因素及物种差别是造成黄花牛耳朵、紫花报春苣苔和桂林蛛毛苣苔适应性产生差异的主要原因。     

不同土壤和微量元素对车桑子幼苗生长的影响

为了解微量元素对车桑子(Dodonaea viscosa)生长的作用,研究添加微量元素(硼B、铁Fe、锰Mn、锌Zn)对车桑子生长和叶绿素荧光特性的影响。结果表明,除Mn外,B、Zn和Fe均对车桑子的生长和叶绿素荧光参数有显著促进作用(P<0.05);且添加B的车桑子具有更高的生物量积累,比对照显著提高了133.61%。微量元素与土壤类型对叶片磷(P)含量和叶片氮磷比(N/P)具有显著的交互作用(P<0.05),紫色土添加Zn、黄棕壤添加Fe均显著降低了叶片N/P。燥红土和黄棕壤上车桑子的株高、叶面积和生物量积累均高于紫色土,但紫色土和黄棕壤上车桑子的根冠比和叶片N/P显著高于燥红土(P<0.001)。这表明微量元素对干热河谷车桑子生长具有重要作用,在植被恢复过程中可通过添加B、Fe、Zn尤其是B来促进植物生长。     

Selected trace elements and esterase activity of carbonic anhydrase levels in lambs with pneumonia

The levels of, zinc, copper, Fe, Zn, Cu, Mn, Mg, K, Na, and Cl and the activity of carbonic anhydrase were determined in lambs with pneumonia. A significant decrease of p<0.01 level in Zn concentration, in Cu level (p<0.001) and significant increases in K and Na levels (p<0.05) and of the Cu/Zn ratio (p<0.001) were observed in the study group. The carbonic anhydrase activity was decreased in the study group, but the decrease was not statistically significant (p>0.05). Also, nonsignificant decreases of Fe, Mg, and Cl and increase of the Mn concentration were also observed in the lambs with pneumonia (p>0.05). Our results suggest that the significant element changes reported here and the Cu/Zn ratio, but not the activity of carbonic anhydrase, can be used as indicators of pneumococcal infection.     

Characterization of natural variation for zinc, iron and manganese accumulation and zinc exposure response in Brassica rapa L.

Brassica rapa L. is an important vegetable crop in eastern Asia. The objective of this study was to investigate the genetic variation in leaf Zn, Fe and Mn accumulation, Zn toxicity tolerance and Zn efficiency in B. rapa. In total 188 accessions were screened for their Zn-related characteristics in hydroponic culture. In experiment 1, mineral assays on 111 accessions grown under sufficient Zn supply (2 μM ZnSO₄) revealed a variation range of 23.2–155.9 μg g⁻¹ dry weight (d. wt.) for Zn, 60.3–350.1 μg g⁻¹ d. wt. for Fe and 20.9–53.3 μg g⁻¹ d. wt. for the Mn concentration in shoot. The investigation of tolerance to excessive Zn (800 μM ZnSO₄) on 158 accessions, by using visual toxicity symptom parameters (TSPs), identified different levels of tolerance in B. rapa. In experiment 2, a selected sub-set of accessions from experiment 1 was characterized in more detail for their mineral accumulation and tolerance to excessive Zn supply (100 μM and 300 μM ZnSO₄). In this experiment Zn tolerance (ZT) determined by relative root or shoot dry biomass varied about 2-fold. The same six accessions were also examined for Zn efficiency, determined as relative growth under 0 μM ZnSO₄ compared to 2 μM ZnSO₄. Zn efficiency varied 1.8-fold based on shoot dry biomass and 2.6-fold variation based on root dry biomass. Zn accumulation was strongly correlated with Mn and Fe accumulation both under sufficient and deficient Zn supply. In conclusion, there is substantial variation for Zn accumulation, Zn toxicity tolerance and Zn efficiency in Brassica rapa L., which would allow selective breeding for these traits.     

Differences in hair density of Japanese monkeys (Macaca fuscata fuscata) with locality and age

The hair density of free-ranging Japanese monkeys (Macaca fuscata fuscata) living in three different areas was investigated. The Japanese monkeys had thicker hair than other macaques. The hair density in the Japanese monkeys varied with locality: the northern monkeys had thicker hair than the southern ones. The density did not vary markedly with age up to 3 years of age, but then decreased gradually up to adult age (≧7 years old). The remarkable growth of the trunk suggested that the total number of hairs increased with age, especially during the period as a juvenile.     

Influence of formula versus sow milk feeding on trace element status and expression of zinc-related genes in the jejunum,liver and pancreas of neonatal piglets

Increasing litter sizes in modern swine production have raised an urgent need for artificial rearing strategies and formula feeding. The current experiment was conducted to study the influence of formula trace element concentration according to recommendations for weaned piglets on the mRNA concentration of zinc (Zn)-related genes in the jejunum, liver and pancreas of neonatal piglets. Eight artificially reared piglets were fed a cow-milk-based formula (Group FO) containing 100 mg Zn/kg dry matter. Eight of their sow-reared littermates (Group SM) were used as control. After 14 d, all 16 piglets were killed and the jejunum, liver and pancreas were evaluated for Zn, copper, manganese (Mn) and iron (Fe) concentration and mRNA concentration of metal and Zn-specific transporters, metallothioneins (MT) and interleukin 6 (IL-6). In Group FO the Zn concentration in liver tissue was increased (p < 0.05). Furthermore, Fe and Mn concentrations in liver and jejunal tissue were higher (p < 0.05) in Group FO, whereas neither Zn transporters nor MT in jejunal and pancreatic tissue showed differences between both groups. In the liver of Group FO, MT mRNA concentration was higher (p < 0.05), whereas Zn transporter protein 1 and divalent metal-ion transporter 1 (DMT1) mRNA concentration was lower (p < 0.05). Besides Zn-induced expression of transporters and MT, the significantly increased IL-6 expression in Group FO suggests the involvement of cytokine-mediated Mn and Fe sequestration in the liver and jejunum. The results revealed that dietary trace element concentration used in the study likely exceeded the requirements of neonatal pigs as reflected by homeostatic counter-regulation in different organs.     

Protective effects of antioxidants against UVA-induced DNA damage in human skin fibroblasts in culture

Ultraviolet A radiation (UVA, 320–400 nm) is mutagenic and induces genomic damage to skin cells. N-acetyl-cysteine (NAC), selenium and zinc have been shown to have antioxidant properties and to exhibit protective effects against UVA cytotoxicity. The present work attempts to delineate the effect of these compounds on genomic integrity of human skin fibroblasts exposed to UVA radiation using the single cell gel electrophoresis (SCGE) or Comet assay. The cells were incubated with NAC (5 mM), sodium selenite (0.6 μM) or zinc chloride (100 μM). Then cells were embedded in low melting point agarose, and immediately submitted to UVA fluences ranging from 1 to 6J/cm². In the Comet assay, the tail moment increased by 45% (1J/cm²) to 89% (6J/cm²) in non-supplemented cells (p<0.01). DNA damage was significantly prevented by NAC, Se and Zn, with a similar efficiency from 1 to 4J/cm² (p<0.05). For the highest UVA dose (6J/cm²), Se and Zn were more effective than NAC (p<0.01).     

Diurnal births and perinatal behavior among wild patas monkeys: Evidence of an adaptive pattern

Data from a 2-year field study of patas monkeys (Erythrocebus patas) in Kenya support our earlier suggestion that diurnal births are a species-typical pattern of patas. In this respect patas are very unusual, as all existing information shows that nocturnal births are typical of both captive and freeranging monkeys. Patas do not give birth at night because to do so would render ineffective their night-resting strategy which reduces vulnerability to predation at night. Giving birth during the day, however, does not eliminate the risk of being preyed on; nor are all times of day equally favorable for giving birth. Our field data suggest that a patas female gives birth at those times of day when she is least likely to lose contact with her group or to encounter predators.     

Polyspecific groups of macaques on the kowloon peninsula,new territories,Hong Kong

Three polyspecific groups of free-ranging macaques were observed in July and August of 1980 and 1981 in the forests of the New Territories of mainland Hong Kong. Two groups were composed of rhesus monkeys (Macaca mulatta) and long-tailed or crab-eating monkeys (M. fascicularis), and one group was composed of both the former plus Japanese macaques (M. fuscata). All three groups contained hybrids between M. mulatta and M. fascicularis. This combination of species within the same social group is an unusual circumstance in natural habitats, and it offers a unique opportunity for field studies in primate ecology and behavior.     

Immobilization and health assessment of free-ranging black spider monkeys (Ateles paniscus chamek)

Eight free-ranging black spider monkeys (Ateles paniscus chamek) were immobilized with Telazol^® in Bolivia for the purpose of radio-collaring. During this procedure, the animals received complete medical examinations, and samples were collected for health analyses. Biochemical test results varied with the degree of condition of the animals, and a variety of physical abnormalities were found. Evidence of previous infections with Leptospira sp., encephalitis virus, and yellow fever virus was found. All findings contribute to establishing baseline health values for the species. The handling of primates for research projects provides a valuable opportunity to collect health-related data and samples that can contribute to wildlife management and conservation efforts. The capture and handling of free-ranging primates is always accompanied by risk of injury or mortality. It is ethically important to maximize the amount of information gathered during these procedures. Furthermore, sharing the undesirable impacts with the scientific community enables informed decisions to be made during future project development. Am. J.

Studies of five microelement contents in human serum, hair, and fingernails correlated with aged hypertension and coronary heart disease

Using atomic absorption spectrometry (AAS), five microelements in human serum, hair, and fingernails of aged hypertension, coronary heart disease (diseased group) and aged health control (healthy group) were detected. Results of the t-test are as follows: The iron, zinc, and cadmium contents and Zn/Cu (mol/mol) ratio of the diseased group were significantly higher than that of the healthy group in serum (p<0.01, p<0.05, p<0.01, and p<0.05, respectively); the chromium contents in the serum, hair, and fingernails (p<0.05, p<0.01, and p<0.05, respectively); the iron and zinc contents in the hair and fingernails (p<0.01, p<0.001, p<0.05, and p<0.01 respectively) and Zn/Cu ratio in the hair (p<0.01) of the diseased group were significantly lower than that of the healthy group. Pathogenic factors of cardiovascular disease have three probabilities: (1) The iron contents of the diseased group were higher than that of the healthy group in serum and lower in hair and fingernails (i.e., abnormal iron metabolism); (2) the zinc contents and the Zn/Cu ratio of the diseased group were higher than that of the healthy group in the serum and the zinc contents in the hair and fingernails and the Zn/Cu ratio in the hair of the diseased group were significantly lower than that of the healthy group; (3) the chromium contents of the diseased group were significantly lower than that of the healthy group in the serum, hair, and fingernails.     

Geophagy as a therapeutic mediator of endoparasitism in a free-ranging group of rhesus macaques (Macaca mulatta)

Parasite levels were determined for 141 members of a naturally formed social group of rhesus macaques living under free-ranging conditions. Results indicate that group members harbor Trichuris trichiura, Balantidium coli, and large numbers of Strongyloides fuelleborni. Parasite counts decrease significantly with age in this population. Females have significantly fewer parasites than males and a significantly lower prevalence of multiple infections. There were no rank effects regarding parasitosis. While 89% of the animals examined are infected with one or more species of enteric parasite, the prevalence of diarrhea is negligible (2%). The low prevalence of diarrhea in the presence of high parasite loads may be due to the practice of geophagy, which is engaged in by 76% of group members. Soil eaten by these monkeys contains large amounts of kaolinitic clays. Kaolin-based pharmaceuticals (i.e. Kaopectate^®) are commonly used in human populations to treat diarrhea and intestinal upsets. The mechanical and pharmaceutical properties of the natural kaolinite-based clays may counteract the effects of parasitosis in this free-ranging population. Am. J.

Serum and tissue levels of six trace elements and copper/zinc ratio in patients with cervical cancer and uterine myoma

The aim of this study is to investigate the relationship between trace elements and the incidence of cervical cancer. Tissue and serum levels of six elements (Cu, Zn, Fe, Mn, Ca, and Se) and the Cu/Zn ratio in 40 cases of patients with cervical cancer, 30 cases of uterine myoma, and 50 healthy subjects were measured by atomic absorption spectrophotometry; the selenium content was determined by atomic fluorescence spectrometry. The results showed that the tissue contents of Zn, Se, and Ca were significantly lower and the Cu and Fe concentrations and Cu/Zn ratio were significantly higher in cervical cancer tissue than that for paired nonlesion tissue (p<0.02 and p<0.001, respectively). The serum levels of Zn, Se, Ca, and Fe were lower and Cu and Mn levels and Cu/Zn ratio were higher in patients with cervical cancer than in healthy subjects (p<0.01 and p<0.001, respectively) and in the uterine myoma group compared with healthy subjects (p< 0.05–0.001). There are no significant differences in the contents of six elements and the Cu/Zn ratio between uterine myoma tissue and paired nonlesion tissue. The results showed also that the Fe level and Cu/Zn ratio were significantly higher and the Zn and Se levels were significantly lower in cervical cancer tissue than in uterine myoma tissue (p<0.01 and p<0.001, respectively). The serum Cu level and Cu/Zn ratio were significantly higher in the cervical cancer group than the uterine myoma group (p<0.01). Data were also analyzed using multivarate logistic regression. After adjustment for age, occupation, life habit, and other covariates for the development of cervical cancer, the odds ratios were 22.64 (95% confidence interval [CI]: 5.64–90.88, p=0.001) for Cu, 0.11 (95% CI: 0.034–0.373; p=0.005) for Zn, and 0.60 (95% CI: 0.36–0.99, p=0.01) for Se. Thus, the serum and tissue levels of Cu increase and the deficiency of Zn and Se may be risk factors for the development of cervical cancer.
