Chemicals in preschools - a study of endocrine disrupting chemicals and awareness among preschool teachers The purpose of this study was to investigate endocrine disrupting chemicals that have been shown in preschools and also the preschool teachers? awareness of these chemicals. There were two methods used for completing this study; a literature study and a practical study. The literature study was made by researching on the internet and in books. The practical study was performed by sending questionnaires to all preschools in Kiruna municipality to study awareness among staff.

The danger and vulnerability associated with a preterm birth seem to be closely correlated with a dysfunction of the fetal hypothalamic-pituitary-adrenal (HPA) axis, whose maturation in the foal is without a doubt as delicate as it is important. Not only is this endocrine cascade vital for the foal in order to cope with neonatal stress, it also appears to be fundamental for the final fetal intrauterine maturation, as well as for the onset of foaling. Equine gestation exhibits some rather unique features, indicating a somewhat different significance of the endocrine changes associated with HPA maturation, compared to many other species. This hormonal cascade is rapid and confined to a narrow time during late gestation in the horse, and the risk of the foal completely missing it therefore becomes prominent. Induced parturition in the mare may be operated through uterotonic agents, which occasionally bring about premature foals. Desirable seems the ability to initiate equine labour while simultaneously enhancing fetal HPA maturation, as in humans and ruminants through perinatal glucocorticoid administration. However, similar treatment in the horse has resulted in various, sometimes fatal, outcomes. In the light of the distinctive features of equine gestation, difficulties are encountered following such administration of glucocorticoids and ACTH.

During the last decades the fertility of dairy cows has declined in the same rate as the milk yield has increased. This is a result of the negative genetic correlation between milk yield and fertility, failure to show estrous signs and metabolic problems in the cow. The purpose of this review was to investigate the function of metabolites and hormones as markers for disturbances in fertility, health and production in the dairy cow. There are several metabolites that are suggested to indicate the cow?s energy balance.

Hyperthyroidism has become the most commonly diagnosed endocrine disorder in cats. The recommended treatment of choice in the literature is administration of radioactive iodine. This treatment has been available at a few veterinary clinics in Sweden since 1999. Forty-six cats treated with a standard dose (80 MBq) of radioactive iodine (131I) at the Swedish University of Agricultural Sciences in the period 2000-2004 were followed for a median of 13 months (range 3-42 months) by means of a retrospective cohort study design. Tables predicting time of survival after treatment were made. At final follow-up thirty-nine cats (85%) were euthyroid, six cats (13%) remained hyperthyroid and one cat (2%) was hypothyroid.

Bakgrund: Bröstcancer är den vanligaste cancersjukdomen bland kvinnor idag och var tionde kvinna drabbas någon gång av sjukdomen. Genetiska faktorer kan öka risken för att drabbas av bröstcancer. Tidig menarche och sen menopaus hör även de till riskfaktorerna. De behandlingsmetoder för bröstcancer som finns tillgängliga är kirurgisk behandling, strålbehandling, cytostatika, hormonpreparat samt annan medicinsk behandling. Indikationen för hormonell behandling är om tumörcellerna har östrogenpositiva receptorer på sin cellyta.

Twitching is frequently used in horse management because of its sedating and pain-relieving effects. In this study, the effects on the horse?s nervous system by twitching were investigated by thermography of the skin temperature. The temperature is regulated by the sympathetic nervous system through postganglionic sfincters at the capillaries of the skin. The effects on the endocrine activity have also been studied by the measuring of ACTH and cortisol in blood plasma.

A number of chemical agents, and their degradation products, have been recognized as having estrogenic activity on animals. On fish they interfere with endogenous estrogen and in many cases mimic its activity, thus increase estrogenic reponse, with elevated levels of vitellogenin. Hence they are called Endocrine Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of exposure to estrogenic pollutants. Wastewater from sewage treatment works contains chemicals known as EDCs, and there are evidence of roach (Rutilus rutilus) living in recipients of such wastewater having traits of both gender, i.e. oocytes in male gonads (intersex) on histological examination. This study was done on roach living in Lake Funbosjön Uppland, Sweden.

The dairy cow?s ability to resume estrus after calving and to conceive is affected by their metabolic status after calving. For high yielding cows there is a high risk that the feed intake will not be sufficient to cope with the increased energy demands after calving, and the cow will end up in a state of negative energy balance. Energy balance can be measured in various ways, for example by body condition score or by plasma concentration of several metabolic hormones and metabolites. After calving, endocrine pathways stimulate tissue mobilization; insulin signaling is blocked, the concentration of insulin-like growth factor-1(IGF-1) and leptin decreases, and the concentration of growth hormone (GH) increases.

Endocrine disruptive chemicals (EDCs) are found in many everyday products and can cause adverse effects on human health. Small children are particularly sensitive to EDCs and they are also exposed to them in a greater extent than adults. Despite this, EDCs are only banned in a few toys and childcare products. There are many sources of exposure and if no steps are taken to reduce the incidence of EDCs we may face an increasing number of people diagnosed with obesity, diabetes type 2 or various types of cancer.The Swedish Government has set a number of environmental objectives, one of which is calleda non-toxic environment. The Swedish Chemicals Agency was instructed to produce and conduct a national action plan to achieve this goal.

Diabetes mellitus (DM) is a relatively common endocrine disease in dogs and is more common in certain breeds than others, e.g. Nordic spitz breeds. Within the Swedish and Norwegian Elkhound population, female dogs are almost exclusively affected. The hypothesis in this study is that Swedish- and Norwegian Elkhounds develop DM during the progesterone phase of estrous (diestrous or pregnancy). Medical records from 51 female dogs of the breeds Swedish and Norwegian Elkhound were studied.

Perfluoroalkyl substances (PFASs) are ubiquitous in the environment today and they have been detected even in remote areas such as the Arctic. PFASs can be transported by the atmosphere and ocean currents but the transport mechanism is not fully understood. PFASs may be harmful to organisms due to their persistence in the environment, bio-accumulation potential and toxicity. Studies have shown that PFASs can cause adverse effects on the metabolism as well as the endocrine- and reproduction systems in organisms. In this study, PFASs were investigated in glaucous gull (Larus hyperboreus) (n=5) and black guillemot (Cepphus grylle) (n=4) from Svalbard.

Chemicals are everywhere in todays society, in humans, animals as well as nature, and they are difficult to avoid. The chemical industry is regarded to be the fastest growing industrial sector, accounting for ten percent of the global economy. A large amount of chemicals are used to produce hygiene products and cosmetics, products that in Sweden only are consumed in quantities of 110 tons per day. Researchers find it increasingly difficult to determine which chemicals that are dangerous and which that are safe, and how they might affect us in the long run. Correlations have been found between chemicals, diseases and other health effects such as cancer, allergies, reproductive and endocrine disorders.

Various problems with nail disorders have been noticed in the Swedish population of Giant Schnauzer, but the frequencies of these problems are unknown. This could be due to the fact that bad nail quality has several differential diagnoses and lack of diagnostic criteria and diagnostic codes for nail disorders. The main purpose of this study is to review different types of claw defects and diseases of the nail bed in dogs, and to classify and evaluate the proportions in the Swedish Giant Schnauzer population. The nail is a specialized part of the skin. The quick will strengthen and protect the third phalang against the surrounding.
