The glands that secrete hormones comprise the endocrine signaling term "hormone" is sometimes extended to include chemicals produced by cells that affect the same cell (autocrine or intracrine signaling) or nearby cells (paracrine signalling).Hormones serve to communicate between organs and tissues for physiological regulation and behavioral activities such as digestion, .

Toxicity involves toxicant delivery to its target or targets and interactions with endogenous target molecules that may trigger perturbations in cell function and/or structure or that may initiate repair mechanisms at the molecular, cellular, and/or tissue levels.

The species specificity of target organ toxicity has been the basis for the understanding of toxic mechanism and development of new active chemicals in the areas of pharmaceutics and agrochemicals. Toxic substances are those which have the ability to cause damage to body organs.
Treatment of several ailments requires the administration of toxic substance that damage a part of some organs. The main mechanism of toxic action of OPs is the inhibition of acetylcholinesterase enzyme activity, causing nervous and respiratory damages that may potentially result in death [ 2, 3 ].
The target site and mechanism of toxic action through which narcosis affects organisms are still unclear, but there are hypotheses that support that it occurs through alterations in the cell membranes at specific sites of the membranes, such as the lipid layers or the proteins bound to the membranes.
the body as a whole. These specific sites are known as the target organs or target tissues. Some examples: Benzene is a specific organ toxin in that it is primarily toxic to the blood-forming tissues.
Lead is also a specific organ toxin; however, it has threetarget organs (central nervous system, kidney, and hematopoietic system). Several heavy metals are found naturally in the earth crust and are exploited for various industrial and economic purposes.
Among these heavy metals, a few have direct or indirect impact on the human body. Some of these heavy metals such as copper, cobalt, iron, nickel, magnesium, molybdenum, chromium, selenium, manganese and zinc have functional roles which are essential for various.
the body. In some cases, chemicals are distributed and stored in specific organs. Storage may reduce metabolism and therefore, increase the persistence of the chemicals in the body. The various excretory mechanisms (exhaled breath, perspiration, urine, feces, or detoxification) rid the body, over a period of time, of the chemical.
Mechanism of Action and Toxicity The mechanism of chemical toxicity of plutonium is thought to be similar to that of uranium, i.e., binding of ionized plutonium molecules to cellular proteins and phospholipids causing membrane damage, enzyme disruption, and organelle derangement.
The target organs for plutonium are the bone marrow and kidney. This chapter is about the liver as a target organ of toxic chemicals. It is a target organ because of: its large blood supply leading to pronounced toxicant exposure and accumulation; its clearance function involving microvasculature, hepatocytes, possibly phagocytic cells, and intrahepatic biliary system; and its pronounced metabolic capacity, critical for internal homeostasis and for.
Types of Toxic Effects. Many factors play a potential role in toxicity. The dosage (or amount of exposure) is the most important factor. A well-known saying, "the dose makes the poison" speaks to this principle. Toxicity can result from adverse cellular, biochemical, or macromolecular changes.
Some. Classification of toxic agents 1) According to the Target organ they are acting on it (hepatotoxic, Nephrotoxic) 2) According to their Use (food additive, drug, pesticide) 3) According to their Source (animal or plant) 4) According to their Effects (carcinogen, mutagen) Target organ is the primary or most sensitive organ affected after exposure.
The same chemical entering the body by different routes of exposure dose, dose rate, sex and species may affect different target organs. The same target organ in different species is frequent (aflatoxin B1, chlorophorm, ochratoxin A, mercury). These specific sites are known as the target organs or target tissues.
Benzene is a specific organ toxicant in that it is primarily toxic to the blood-forming tissues. Lead is also a specific organ toxicant; however, it has three target organs: the central nervous system, the.
This volume is devoted to specific organs with coverage of the gill, kidney, skin, liver and gut. The companion volume, Systems, provides coverage of toxic effects in the central nervous, immune, neurobehavioural and reproductive systems as well as describing general mechanisms of toxicity.
This book is based on reviews and research presentations given at the 16th Rochester International Conference on Environmental Toxicity, entitled liThe Cytoskeleton: A Target for Toxic Agents," held on June 4, 5 and 6 in The conference provided an in-depth discussion of the effects a~d. Within the system, anticancer drugs including tamoxifen, diclofenac, imatinib, and verapamil demonstrated variable on-target and off-target effects, some of which were dependent on drug metabolism by liver cells.
This study supports the use of simple yet versatile multi-organ cell-based systems for efficient preclinical drug testing. Pharmacokinetics, metabolic activation and key defense mechanisms, excretion, species variation, and tissue-specific biochemistry are explored comprehensively.
These general principles are then illustrated using specific examples of toxicity to different target organs and systems. When a toxic dose is ingested (see below), paraquat has life-threatening effects on the gastrointestinal tract, kidney, liver, heart and other organs.
The LD 50 in humans is approximately mg/kg, which translates into as little as mL of a 20% solution.1,2 In spite of the fact that the lung is the primary target organ, toxicity from.
The lungs are a target organ in acute high-dose exposures to inhaled cadmium fumes. Mechanisms of Toxicity Cadmium is known to increase oxidative stress by being a catalyst in the formation of reactive oxygen species, increasing lipid peroxidation, and depleting glutathione and protein-bound sulfhydryl groups.
Specific Target Organ Toxicity – Single Exposure March Note: The specific target organ/organ system that has been primarily affected by the classified substance shall be identified, where possible, and where this is not possible, the substance shall be identified as a general toxicant.
This mechanism of action provides bacteriostatic inhibition of growth against a wide spectrum of gram-positive and gram-negative pathogens. Because humans obtain folic acid from food instead of synthesizing it intracellularly, sulfonamides are selectively toxic for bacteria.
The respiratory system is both a target organ and a portal of entry for toxicants. Asthma morbidity and death from asthma are increasing.
More than toxicants cause asthma, and many more can exacerbate it [Rom ]. A large number of xenobiotics and occupations are associated with the development of work-aggravated and work-related asthma.
Auxins help development at all levels in plants, from the cellular level, through organs, and ultimately to the whole plant. Molecular mechanisms. When a plant cell comes into contact with auxin, it causes dramatic changes in gene expression, with many genes up- or down-regulated.
The precise mechanisms by which this occurs are still an area of. Target Organ Toxicity, 2 • Toxicants do not affect all organs to the same extent. • A toxicant may have several sites of action and target organs. • Multi-toxicant exposure may target the same organ.
