Healing of tissue -Repair,process pathology notes

                            HEALING OF TISSUE  Hello, doctor vanakam, The topic of discussion for today is the healing of tissues as I had informed earlier on the previous post on shock- pathology  here is the link for the previous post do check it out if you haven't seen it yet. without any further ado, let's get started. CONTENTS: 1) INTRODUCTION TO HEALING 2)DEFINITION OF REPAIR AND ITS PROCESS 3) PHASE OF GRANULATION TISSUE FORMATION 4)HEALING BY THE FIRST INTENTION 5) DIFFERENCE BETWEEN FIRST AND SECOND INTENTION 6)COMPLICATION OF WOUND HEALING  1) INTRODUCTION: Healing is the body's response to injury in order to restore normal structure and function. It involves 2 processes: REGENERATION: Healing by a proliferation of parenchymal cells that results in complete restoration of the original tissue. 2) DEFINITION OF REPAIR : Healing by the proliferation of connective tissue that results in fibrosis and sca

Sterilization technique in microbiology

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.

  VIRUS STRUCTURE AND CLASSIFICATION Virus are obligate intercellular  organism sub microscopic entity consisting of a single nucleic acid surrounded by a protein coat and capable of replication only within the living cells  STRUCTURE: size: 10-100 nm; 1/10th size of bacterium . shape : spherical genome material : DNA OR RNA; never both  protective shell:    capsid : Its made of any identical protein subunit they protect gentic material ,symmetrically organised. Envelope :  lipid containing membrane that surrounds the virus particle located outside the capsid acquired during replication . CLASSIFICATION OF VIRUS: A) BASED ON MORPHOLOGY B) CHEMICAL COMPOSITION C)      MODE OF REPLICATION THANKS FOR READING  NOTE:please feel free to comment down your valuable suggestion below .
