Asbestos Exposure Cancer And Lymphoid Structures

Inhalation of asbestos fibers can lead to a deadly form of cancer called mesothelioma. Some theories stated that asbestos can actually travel through the blood stream and enter organs like the kidney, or even the brain. One interesting study is called “Asbestos Exposure and Gastrointestinal Malignancy Review and Meta-Analysis” by Howard Frumkin, MD, Jesse Berlin.

The epidemiologic literature linking asbestos exposure with gastrointestinal malignancy is reviewed. The study is comparing problems to be discussed, find appropriate strategies for comparison are developed and result of the study are pooled using a model which accounts for both intrastudy and interstudy variability.

Asbestos exposure cancer and lymphoid structures

Stratification of cohorts by dose reveals that significant asbestos exposure, as indicated by a lung cancer standardized mortality ratio (SMR) of at least 200, is associated with an elevated gastrointestinal cancer SMR for five or six end points examined.+

Another interesting study is wntitled “Migration of Asbestos Fibres from Subcutaneous Injection Sites in Mice” by K. Kanazawa, M. S. C. Birbeck, R. L. Carter, and F. J. C. Roe – Br J Cancer. 1970 Here is an excerpt:

Crocidolite asbestos fibres, suspended in physiological saline, were injected subcutaneously into one or both flanks of 95 CBA/Lac female mice; 75 control mice received injections of saline only. Most animals were killed at chosen intervals of between 2 and 42 days after injection but some were left for longer periods of up to 623 days.

At autopsy, many lymphoid and non-lymphoid structures were removed and examined for the presence of asbestos by the following techniques: haematoxylin and eosin staining followed by conventional and polarized light microscopy; Perl’s stain; microincineration followed by phase-contrast microscopy; maceration with KOH followed by phase-contrast microscopy; and electron microscopy.

A combination of haematoxylin and eosin staining and microincineration was found to be the most convenient and reliable method for demonstrating asbestos fibres in the tissues. Electron microscopy was essential for detecting very small fibres and for locating them to specific intracellular structures.

The morphological findings indicate that some migration of asbestos fibres away from the initial site of injection takes place. Dissemination is usually along lymphatic pathways and fibres tend to accumulate in the lymphoid tissues, particularly in the regional (axillary) lymph nodes; smaller amounts were found in inguinal, mediastinal and lumbar nodes.

The fibres were usually intracellular, lying inside the phagosomes of macrophages, but larger fibres were sometimes encountered lying free. Small numbers of fibres were seen in the spleen and also in non-lymphoid organs such as the liver, kidneys and brain which is suggesting that some asbestos may enter the blood stream.

There was no evidence of massive or selective spread to subserosal tissues in the thorax or abdomen, though trapping of asbestos fibres was observed in pleural milky spots in long-term survivors. The possible role of milky spots in the development of pleural plaques and mesotheliomata is discussed.

A third article worth looking at is called “Asbestos inhalation induces reactive nitrogen species and nitrotyrosine formation in the lungs and pleura of the rat” by S Tanaka, N Choe, D R Hemenway, S Zhu, S Matalon, and E Kagan – Department of Pathology, Uniformed Services University of the Health Sciences, F. Edward Hibert School of Medicine, Bethesda, Maryland 20814-4799- J Clin Invest. 1998 July 15; 102(2): 445+454.

Here is an excerpt:

To determine if asbestos inhalation induces the formation of reactive nitrogen species, three groups of rats were exposed intermittently over 2 wk to either filtered room air (sham-exposed) or to chrysotile or crocidolite asbestos fibers. At 1 or 6 weeks after exposure, the rats were killed.  At 1 week, significantly greater numbers of alveolar and pleural macrophages from asbestos-exposed rats than from sham-exposed rats demonstrated inducible nitric oxide synthase protein immunoreactivity.

Alveolar macrophages from asbestos-exposed rats also generated significantly greater nitrite formation than did macrophages from sham-exposed rats. The evident from chrysotile is strong immunoreactivity for nitrotyrosine, a marker of peroxynitrite formation. A crocidolite-exposed rats at 1 and 6 week.

Themost evident at alveolar duct bifurcations and within bronchiolar epithelium, alveolar macrophages, and the visceral and parietal pleural mesothelium was staining. These findings suggest that asbestos inhalation can induce inducible nitric oxide synthase activation and peroxynitrite formation in vivo, and provide evidence of a possible alternative mechanism of asbestos-induced injury .

Gardening catalogs also have all of the tools you need for any kind of gardening.  If you have a hydroponics garden you can request a timed water pump or artificial lighting.  You can request pruning shears for shrubs or a gas operated tiller to separate your dirt.  Catalogs will offer you a full selection of gloves, making it possible to discover a pair that is functional and fashionable.  Other equipment that can be bought includes hoes, rakes, spades, shovels, water hoses, and sprinklers.

Gardening catalogs give gardeners with a large selection of seeds and plant kinds can be discovered anywhere else.  The best plus about catalogs is everything offered to you at once.  You can check out what is suitable and took and choose what you desire to plant based on the requirements, like the plant’s maintenance, time, and climate needs.  A gardening catalog provides you the luxury of look at every plant type all at once, preparing it much simple to make a choice.

Gardening catalogs are extremely helpful.  If you do not live around a nursery or some type of gardening store, it is hard to find all of the things you want to begin and keep a healthy garden.  Let’s face it; Wal-Mart doesn’t have everything needed for a garden.  Gardening catalogs give you more choice and grant you to view everything provide at a single setting.  Whether you are in the market for seeds or tools, a gardening catalog is the only important way to go.

Remodeling a Small Bathroom

Remodeling a Small Bathroom

Designs for smaller and space efficient rooms are being sought while bigger and luxurious spaced rooms is still in everyone’s fancy. People will be interested in those which are economical in space and money.

Regarding modest households setting up on a highly urbanized locality, such thing is evidently true. For instance, New York and the surrounding suburbs of Boston and Washington DC with its high density populations, leads the highly posh and sophisticated accommodations yet the pursuit for smaller.

How to design such miniscule spaces is one thing that plagues conservatives homeowners though. You cannot make semi Spartan furnishings yet speak of comfort and elegance in bathroom and kitchen areas not like in bedrooms and living rooms. So you wonder how to do an effective small bathroom remodeling.

Installation doesn’t have to be sacrificed. There would be others that just can’t forgo the absence of tubs and saunas while some modern bathroom models sport only a shower room, a toilet, and a contemporary vanity from personal taste. Those small bathrooms can be entirely occupied by both monstrous tub and a sauna tub.

Nowadays, compactness of facilities is achievable. Without sacrificing comfort, there are bathroom products that have evolved to meet the criteria for space consciousness. The Wasauna Steam Shower and Whirlpool Combo WAS-2245 for instance. this is what the Wasauna Steam Shower and Whirlpool Combo offers: a shower room with a tub and with the capability of a steam or sauna bath, grouping together  several bath essentials. Space efficiency becomes an achievable concept by having the features of several facilities in one bulk machine.

The spaciousness of the room is affected by colors and tones. White or light colors do make these snug quarters more spacious than they seem while darker tones do promote coolness which is also a pleasant factor in restrooms and bathrooms. It also prevents the feeling of being claustrophobic and cramped.

Try to install ceiling to floor mirrors on opposite ends on your small bathroom remodeling because installing mirrors tend to give the illusion of spaciousness. It also allows “spaciousness” by adding an illusion to several feet of space, not only they allow a vital view of your rear.

If you install those stated above to the letter, a few fixtures of bright white lights are the perfect last compliment. The room will still have the lively bright illumination even if you install lights in less conspicuous places because mirrors do multiply brightness several times over.
