General Anaesthetics

General Anaesthetics

General anesthetics (GAs) are drugs which produce reversible loss of all sensation and consciousness.The cardinal features of general anaesthetic:
 

  • Loss of all sensation,specially pain
  • Sleep (unconsciousness) and amnesia
  • Immobility and muscle relaxation
  • Abolition of somatic and autonomic reflexes


In the modern practice of balanced anaesthetics,this modalities are achieved by using combination of inhaled and i.v. drugs,each for a specific purpose. Anaesthetics has developed as a highly specialized science in itself.

Diabetes

  What is Diabetes ?  Diabetes refers to a group of conditions characterized by a high level of blood glucose, commonly referred to as blood sugar. Too much sugar in the blood can cause serious, sometimes life-threatening health problems.There are two types of chronic diabetic conditions: type 1 diabetes and type 2 diabetes. Pregnant women may acquire a transient form of the disease called “gestational diabetes”which usually resolves after the birth of baby. Pre-diabetes is when the blood sugar level is at the borderline: higher than normal, but lower than in diabetics. Prediabetes mayor may not progress to diabetes. During food digestion, carbohydrates - or carb - break down into glucose which is carried by the bloodstream to various organs of the body. Insulin is a hormone produced by beta cells of the pancreas and is necessary for glucose intake by target cells. In healthy people, beta cells of the pancreas produce insulin; insulin binds to its receptor on target cells and ...

Vaccine Work Mechanism

How Vaccines work ?                                                                               Vaccines prepare the immune system, getting it ready to fight disease-causing organisms, called pathogens. To understand how vaccines work, we must first learn how our immune system responds to invading pathogens. When a new pathogen enters the body, it meets with the body’s first-line defense, the innate division of the immune system. The innate response is immediate, but non-specific,meaning it destroys all foreign invaders without discrimination. Fever is one of the signs that the body is fighting the disease at this stage. If this fails to contain the infection, the adaptive immune system comes into play. The adaptive response is more effective, but it may take many days to activate, during...

Adrenergic Drugs

Mechanisms of action & Classification  Adrenergic drugs are medications that stimulate or inhibit adrenergic receptors. Adrenergic receptors mediate the action of noradrenaline, also known as norepinephrine; and adrenaline, also known as epinephrine. Adrenergic neurotransmission is responsible for the body’s sympathetic response - the “fight or flight” state - which dilates pupils, increases heart rate and respiratory rate, diverts blood flow to the muscles, inhibits activities that are not essential in emergency, and releases stored energy. Adrenergic receptors are also active in the central nervous system, in processes such as memory and alertness. There are several types of adrenergic receptors,all of which are G-protein coupled, but they differ in several aspects:- They couple with different G-proteins, leading to different downstream signalings, and hence different cellular responses. - They differ in sensitivity to different drugs. - While several receptors may coexist i...
