CLINICAL CHEMISTRY Blog Notes 20B: Endocrinology, Toxicology, and Drug Testing

ENDOCRINOLOGY

so what is endocrinology about? hormones? so according to my resources...

Endocrinology is a study that deals with the endocrine system and its specializede glands which secretes chemical substances called hormones. It also includes the study of the chemistry functions of hormones of the specialized glands and tissues.These glands which transfers information from one set of cells to another enables the organism to adjust various activities of the body to the changing demands of the external and internal environment.

TOXICOLOGY

toxic a term used to describe something that's been killing us in every manner somehow haha! :P just like how would i describe situations in my life that would almost kill me like my studies and yun lang naman nagpapahirap sakin... tae!! haha

in terms of medical field...Toxicology is the study of poisons, their effects, and antidrotes. Toxicity is the ability of a substance to produce injury upon reaching a susceptible site in or on the body.

And do you know that the dosage period and the period of time over which the dosage occurs determine the effect of a substance on an organism so normally even safe substances can cause illness or death if consumed insufficient amounts or too much intake.

in addition... Toxiclogy has been branched into specialized areas depending on how organisms can be exposed to these substances by various routes. These specialized areas would include:

• Economic toxicology- concerned with chemicals used in drugs, food additives, pesticides, and cosmetics.

• Forensic toxicology- involving the medical and legal aspects of poisonous materials when death or severe injury is the result of their use.

• Industrial toxicology- in which the effects of pollutants in the working environment are evaluated.

• Environmental toxicollogy- which is the evaluation of the synergistic effects of chemicals in the environment.

Drug Testing

drugs as we all know are good somehow for panandaliang aliw but seriously you can put your self into a hell when you deal with this stuffs anyway in the end you might find yourself in prison... and by how?? by DRUG TESTING!

so....Drug testing or drug screening is performed to detect small amounts of any number of metabolites of commonly used drugs. Drug screens are available for a variety of substances including amphetamines, barbiturates, benzodiazepines, cocaine, methamphetamine, opiates (morphine and herioine), cannabinoids (marijuana), phenycyclidine, and propoxyphene.

Not only is drug testing helpful in identifying users but it also acts as a deterrent.

Substance abuse testing has used urine exclusively as the sample of choice which is generally inexpensive, easily obtained, plentiful and contains large amount of drugs and metabolites.

for example: urine can identify drug usage for 7 to 14 days after the last usage, whereas blood testing reflects drug usage only during the past few hours. Saliva, breath, hair and sweat are becoming increasingly important and accurate specimens for specific drug testing however they are expensive.

drugs makes you ugly!!
