Exposure to asbestos can cause fatal diseases dangerous.
When asbestos fibers are broken or crushed into small pieces, they can be
inhaled or ingested, and attack the body. One interesting study is called,
"genetic effects of crocidolite in Chinese hamster lung cells," Huang
SL, D. Saggioro, H. Man and Michel HV Malling, Mutation Research / Fundamental
and molecular mechanisms of mutagenesis, Volume 57, Number 2, 1978, pp. 225
-232. This excerpt: "Summary - cells Chinese hamster lung in the presence of
crocidolite showed inhibition of cell growth, death of the cultured cells is
directly related to phagocytosis than observed with trypan blue soluble
components connected fibers apparently inhibits crocidolite cell growth
chromosome aberration caused by asbestos is broken and fragments .... -.
aberrations limited mainly to structural aberrations preparation for electron
microscopy showed that the asbestos content in phagocytosed asbestos phagosomes
rapidly appeared to be a weak mutagen in their ability to mutations in the gene
locus increases hypoxanthine guanine. " .
Another interesting study is called, "the mortality of
cohorts exposed to chrysotile asbestos" White, William MD - Journal of
Occupational and Environmental Medicine: October 1977 - Volume 19 - Issue 11
Here is an excerpt: "Abstract - age cohort mortality 30,264 historic men
was held from 1935 to 1945, while factory chrysotile products worked for a year
or more and who were alive on January 1, 1945 observation. 94% complete., the
whole course of the mortality ratio standardized (SMR) is only 0.61, while the
SMR for all cancers was 0.75 for lung cancer, 0.93 and 1.05 for
gastrointestinal cancer. Both men died from asbestosis. all SMR was higher for
men who have five or more years than men who worked 1 -4 years of work, but the
mortality rate in the 30 were the same after adjusting for age. diseases hours
differences asbestos-related work has no effect on mortality., the data show a
positive mortality experience of men exposed only to chrysotile. "
Another interesting study is called, "washing
asbestos-related lung reflect the concentration of asbestos bodies" De
Vuyst P, Dumortier P, E Moulin, N Yourassowsky, Roomans P, P Francquen and JC
YERNAULT - Eur Respir J 1988 , 1: 362 -367. Here is an excerpt: "Asbestos
body (AB) counts both bronchoalveolar lavage fluid (BAL) and lung tissue
samples were digested in a hundred patients who underwent thoracotomy
procedure, especially for lung cancer shows a good correlation. (P = 0.73)
between the two sets of values of the entire group of objects found., if
taken into account when choosing a restrictive as washing ipsilateral easy to
analyze, interpret qualified doctor adopted a better correlation ( R = 0.82).
No. AB low sperm count or AB (AB least 1 / ml) BAL approximately 70% less than
1,000 AB / g concentrations and less than 100% 10 000 concentrations ab / g.
Los BAL patients with more than one AB / ml 85% of lung tissue comprises more
than 1000 AB / g tissue and contained more than 44% 10,000 b / g A 10 AB / ml
of BAL, all contained in lung tissue over 10 000 AB / G With the lung tissue is
not readily available for patients undergoing consideration by asbestos
exposure, BAL analysis appears to be a useful tool for assessing the
concentration of light AB. This technique can be done, but only in patients
with severe respiratory failure that does not allow adequate recovery BAL
".
