HELLO! DOCTOR VANAKAM, I hope you all are doing good today we will be discussing sterilization various methods of sterilization, about dry heat sterilization and moist heat sterilization along with different methods employed, and what are the materials to be placed in this method in detail about autoclave its principle, working and of course uses. As I have had already informed you all through my previous post on the contribution of Louis Pasteur and Koch postulates if we haven't checked it out yet do check it out using this link   https://www.stencildent.com/2020/07/contributions-of-louis-pasteur-and-koch.html  wherein I would explain the importance for the need of the HOUR and always to sterilize things to and from the patients and also get geared up for the next post on SHOCK wherein I would cover the definition, types, classification along with etiology, pathogenesis, flow chart, the complication of septic shock in detail so now without any further ado lets get starte...

                          HYPERSENSITIVITY   hello, doctor vanakam, I hope you all are doing good, as intimated through the last post on anaerobic culture method  https://www.stencildent.com/2020/08/anaerobic-culture-methods-microbiology.html  if u haven't checked it out do read using this link without any further ado lets get started. CONTENTS: 1)Definition 2)Classification 3)type 1 hypersensitivity reaction a)1st exposure b)2nd exposure c)mediators of reaction d)late-phase reaction 4)type 4 hypersensitivity 5)treatment  1)DEFINITION: It refers to a condition in which immune response results in excessive reaction leading to tissue damage, disease, or even death in a sensitised host. 2) CLASSIFICATION: Coomb and gel classification in 1963 into type 1 to 4  Type 1,    type 2, type 3       : They depend on the interaction of antigen with humoral antibodies They are the i...
