v. Pulmonary Oedema
vi. Primary and secondary tumours of the lungs.

On Examination :
i. color of serous fluid are clear and straw-colored with characteristically  transudate.
ii. Specific gravity is under 1.012
iii. Protein contents below 1gm/dl and find little cellular content also.

Clinical Features : 
  • If the fluid collection in pleural cavity is less than 300 ml ( normal less than 15 ml) no signs or symptoms are produced and may be appear in chest X-rays in standing posture as obliterated costodiaphragmatic angle.
  • If fluid collection in pleural cavity is more than 300 ml that is the part of characteristic opaque radiographic appearance to the affected side with deviation of trachea to the opposite side.
  • Respiratory embarrassment (rapid shallow breathing with inspiratory dyspnoea) and dyspnoea are also produced.

Lysosomes

Image
Name :- Lysosomes, garbage system of the cell, suicidal bag of the cell Properties : These are membrane bound vesicular structures founds throughout the cytoplasm. These are formed by the process of packaging in the golgi apparatus. Enzymes of lysosomes are synthesized in rough endoplasmic reticulum. Among the organelles, the lysosomes have the thickest covering membrane that is formed by a bilayered lipid material . Lysosomes have 50 different hydrolytic enzymes, known as acid hydroxylases. Types of Lysosomes : Primary lysosomes, this is an inactive of form of lysosomes. Secondary lysosomes, this is an active form of lysosomes (lysosomes active during phagosome or endosome and at this time lysosomes pH become acidic and enzymes are activate). Lysosomal Enzymes :   Proteases :- which hydrolyze the proteins into amino acids. Lipases :- which hydrolyze the lipids into fatty acids and glycerides. Amylases :- which hydrolyze the polysaccharides into glucose. Nucleases :- whi

Pneumonia

Pneumonias  Definition :  It is an acute inflammation of lungs parenchyma with consolidation distal to terminal bronchioles ( consisting of the respiratory bronchiole, alveolar ducts, alveolar sacs and alveoli ).It may be infective and non-infective. Pathogenesis :  Microorganism can enter into the lungs by following route after  failure of defensive mechanism  - i. Inhalation of air microbes. ii. Aspiration of the microbes from the nasopharynx or oropharynx. iii. Haematogenous spread from a distant focus of infection such as - vector population, environmental characteristics. iv. Direct spread from a adjoining site of infection. Classification : 1. On the basis of anatomical regions - Lobar Pneumonia Bronchopneumonia or Lobular Pneumonia Interstitial Pneumonia Features of lobar and lobular pneumonia 2. On the basis of clinical aspects - Community-acquire Pneumonia Health care-associated Pneumonia (Hospital acquired Pneumonia) Ventilator-associated Pneu
