Q

what is osmotic diarrhoea?

A

With osmotic diarrhoea, electrolyte transfer takes place but at a low rate. The majority of the fluid passed will be unabsorbed chyme with some fluid drawn osmotically from the cellular membrane. If you stop drinking the diarrhoea will stop

Q

What are the reasons to query antibiotic use in diarrhoea in the uk?

A

Antibacterial drugs are generally unnecessary in simple gastro-enteritis because the complaint usually resolves quickly without them, and infective diarrhoeas in the UK often have a viral cause. Systemic bacterial infection
does, however, need appropriate systemic treatment.

they Phagocytose pathogens, and other biological debris. | Anti and pro infammation cytokine release.
39
What do Natural Killer cells do?
NK cells play a major role in the host-rejection of both tumours and virally infected cells. NK cells are cytotoxic; small granules in their cytoplasm contain special proteins such as perforin and proteases known as granzymes
40
what do B cell (memory) do?
memory cells remember the same pathogen for faster antibody production in future infections
41
what do B plasma cells do?
They produce a single kind of antibody but do it at an incredible rate.
42
what do t helper cells do?
CD4 cells activate cytotoxic T cells and macrophages to attack infected cells, or they stimulate B cells to secrete antibodies.
43
What do T killer cells do?
CD8 Killer T-cells find and destroy infected cells that have been turned into virus-making factories.
44
Function of IL-1
