OBJECTIVE
To evaluate the relationship between arsenic exposure and oral cavity lesions among an arsenic-exposed population in Bangladesh.
METHODS
We carried out an analysis utilizing the baseline data of the Health Effects of Arsenic Exposure Longitudinal Study, which is an ongoing population-based
BACKGROUND
Inorganic arsenic has been used by many laboratories to study the pathogenesis of exencephaly in rodents. These studies, which used predominantly injection exposures, coupled with the paucity of epidemiology data, resulted in the erroneous inference that inorganic arsenic should be
OBJECTIVE
To further clarify the effects of arsenic on pregnant rats, fetuses, fetal cells and to verify the experimental results in vitro, and to study the developmental toxicity and its mechanisms of arsenic in depth.
METHODS
Teratogenic methods in vivo combined with scanning electron microscopy
OBJECTIVE
To study the role of arsenic trioxide (As(2)O(3)) in regulating peritoneal invasive activity of ovarian carcinoma cells in vitro and in vivo.
METHODS
The effects of As(2)O(3) on human ovarian cancer cell lines (3AO, SW626 and HO-8910PM) migration, invasion and adhesion with tumor cells and
OBJECTIVE
Arsenic trioxide (As2O3) has been successfully used to treat the patients with acute promyelocyutic leukemia in clinic, and for the experimental studies of liver cancer, colorectal cancer, gastric cancer, etc. The objective of this study was to explore the inhibitory effect of As2O3 on the
The electrochemical reduction of inorganic As on a graphite cathode depends on the current density. We observed that while only inorganic As(III) is reduced to AsH(3) at low current densities, at high current densities both forms of inorganic As are reduced. We describe a unique electrochemical
Whole-body autoradiography in combination with other determinations of tissue levels of 74As-arsenic in mice, 5 min. to 30 days after intravenous injections of 74As-arsenite (As III) or -arsenate (As V), showed higher organ concentrations and whole-body retention of arsenic in the As III mice as
OBJECTIVE
To study the effect of arsenic trioxide (As(2)0(3)) on human hepatoma cell line BEL-7402 in vivo.
METHODS
Human hepatoma cell line BEL-7402 cultured in vitro was inoculated into nude mice and arsenic trioxide, 5-Fu and saline were injected into abdominal cavity of the nude mice
Blackfoot disease was prevalent in a limited area on the southwest coast of Taiwan, where artesian well water containing arsenic (median = 0.78 ppm arsenic) had been used for many years. Previous studies of arsenic exposure in the blackfoot disease endemic area have been focused on malignant tumors.
This cross-sectional study was carried out in some selected arsenic contaminated rural areas of Bangladesh to determine any clinical changes in oral cavity, among the arsenic exposed population through drinking water. Total 600 respondents (200 arsenicosis patients, 200 non-patients but having the
A critical analysis of the literature base regarding the reproductive and developmental toxicity of arsenic compounds, with emphasis on inorganic arsenicals, was conducted. The analysis was stimulated by the great number of papers that have purported to have shown an association between exposure of
OBJECTIVE
This is an update of an earlier study on the relation between exposure to arsenic in air and deaths from respiratory cancer. The purpose was to verify earlier findings of a supralinear dose response relation and to examine relations with other cancers, particularly those reported in
Groundwater is a much safer and more dependable source of drinking water than surface water. However, natural (geogenic) hazardous elements can contaminate groundwater and lead to severe health problems in consumers. Arsenic concentrations exceeding the WHO drinking water guideline of 10 μg/L
