Factors that regulate distal tubular secretion of K+ are intake of Na+
and K+, plasma concentration of mineralocorticoids and acid-base
balance. Dimished glomerular filtration rate and the consequent decrease
in distal tubular flow rate is an important factor in the retention of
K+ seen in chronic renal failure. Renal tubular acidosis, and metabolic
and respiratory acidoses and alkaloses also affect renal regulation of
K+ excretion (Mattew, 2003).2.6.4.6 Effect of Toxic Chemicals on the Kidney
The kidney is susceptible to toxic agents for several reasons:
(1) The kidneys constitute 1 percent of the body's weight, but receive 20-25 percent of the blood flow (during rest). Thus, large amounts of circulating toxicants reach the kidneys quickly.
(2) The kidneys have high oxygen and nutrient requirements because of their workload. They filter one-third of the plasma reaching them and reabsorb 98-99% of the salt and water. As they are reabsorbed, salt concentrates in the kidneys.
(3) Changes in kidney pH may increase passive diffusion and thus cellular concentrations of toxicants.
(4) Active secretion processes may concentrate toxicants.
(5) Biotransformation is high.
A number of materials are toxic to the kidneys:
• Heavy metals, may denature proteins as well as produce cell toxicity. Heavy metals (including mercury, arsenic, gold, cadmium, lead, and silver) are readily concentrated in the kidneys, making this organ particularly sensitive.
• Halogenated organic compounds, which contain chlorine, fluorine, bromine, or iodine. Metabolism of these compounds, like that occurring in the liver, generates toxic metabolites. Among compounds toxic to the kidneys are carbon tetrachloride, chloroform, 2,4,5-T (a herbicide), and ethylene dibromide (a fumigant),others includescarbon disulfide (solvent for waxes and resins) and ethylene glycol (automobile antifreeze) (Ariens et al., 2016 ). Heavy metals such as cadmium (Cd), mercury (Hg), lead (Pb), chromium (Cr) and platinum (Pt) are a major environmental and occupational hazard. Unfortunately, these non-essential elements are toxic at very low doses and non-biodegradable with a very long biological half-life. Thus, exposure to heavy metals is potentially harmful. Because of its ability to reabsorb and accumulate divalent metals, the kidney is the first target organ of heavy metal toxicity. The extent of renal damage by heavy metals depends on the nature, the dose, route and duration of exposure. Both acute and chronic intoxication have been demonstrated to cause nephropathies, with various levels of severity ranging from tubular dysfunctions like acquired Fanconi syndrome to severe renal failure leading occasionally to death. Very varied pathways are involved in uptake of heavy metals by the epithelium, depending on the form (free or bound) of the metal and the segment of the nephron where reabsorption occurs (proximal tubule, loop of Henle, distal tubule and terminal segments). In this review, we address the putative uptake pathways involved along the nephron, the mechanisms of intracellular sequestration and detoxification and the nephropathies caused by heavy metals. We also tackle the question of the possible therapeutic means of decreasing the toxic effect of heavy metals by increasing their urinary excretion without affecting the renal uptake of essential trace elements. We have chosen to focus mainly on Cd, Hg and Pb and on in vivo studies (Karger, 2005)
2.6.5.0 Enzyme Profile in Liver Diseases
2.6.5.1 Aspartate Transaminase (AST) catalyzes the reversible transfer of an α-amino group between aspartate and glutamate and, as such, is an important enzyme in amino acid metabolism. AST is found in the liver, heart, skeletal muscle, kidneys, brain, and red blood cells (Chatterjea and Rana, 2012).
2.6.5.2 Alanine aminotransferase (ALT) is a transaminase enzyme that was formerly known as serum glutamate pyruvate transaminase (SGPT). Alanine aminotransferase catalyzes the transfer of an amino group from alanine to alpha-ketoglutarate in the alanine cycle to form pyruvate and glutamate.2 biological function of Alanine Amino Transferase (Chatterjea and Rana, 2012 )
2.6.5.3 Alkaline Phosphatase (ALP)
ALP is a nonspecific enzyme that hydrolyses aliphatic, aromatic or heterocyclic compounds. The PH optimum for the enzyme reaction is between 9 and 10. It is activate by magnesium and manganese. Zinc is a constituent ion of ALP (Chatterjea and Rana, 2012).

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.1 Background of studyCosmetology which include nail and hair care has become a lucrative profession. (Halliday-Bell et al., 2009). The use and application of cosmetics have been shown to have some effects on the human system. There are about 9000 chemicals ingredients found in cosmetic products (Kersemaekers and Roelveld, 1995). Nail and hair care users have daily contact with cosmetic products and are therefore routinely exposed to a wide range of chemicals by inhalatio ... Continue reading---
