                      Pharmacology practical No.2

Theory:-

1.Physiological pH:-

Tyrode's solution is designed to maintain a physiological pH of around 7.4.which is the normal pH of blood.

2.Ionic composition:-

 The solution contains a mixture of salts including sodium, chloride potassium, chloride calcium chloride, and magnesium chloride, which are present in the same proportions as in blood.

3.Buffering capacity:- 

Tyrode's solution contains a buffer system typically a phosphate buffer which helps to maintain the pH of the solution.

4.Osmolality:-

The solution is designed to have an osmolality similar to that of blood which helps to maintain the structural integrity of cells and tissues.

_Composition:_

A typical Tyrode's solution contains the following components:

- 

_Preparation:_

To prepare Tyrode's solution, the individual components are weighed and dissolved in distilled water. The solution is then adjusted to the desired pH and osmolality.

_Steps:_

1. Weigh the individual components.

2. Dissolve the components in distilled water.

3. Adjust the pH to 7.4 using sodium hydroxide or hydrochloric acid.

4. Adjust the osmolality to 290-300 mOsm/kg using sodium chloride or glucose.

5. Filter the solution through a 0.2 μm filter to remove any impurities.

Apparatus:-

1=weight balance 

2=beaker

3=spatula

4=stirrir

5=funnel

6=flask

Ingredients used:-

To prepare Tyrode solution you will need the following materials:

- Sodium chloride (NaCl)

- Potassium chloride (KCl)

- Calcium chloride (CaCl2)

- Magnesium chloride (MgCl2)

- Sodium bicarbonate (NaHCO3)

- Sodium phosphate (NaH2PO4)

- Glucose

- Distilled water

Procedure:-

1 Wash all apparatus and let's dry them

2 weight all ingredients accurately

3 take a beaker and add small quantity of water in it

4 add NACL and kCL and mix it properly

5 than add cacl2 and NAH2PO4 mix it 

6 than add mgcl2 and mix it completely

7 add dextrose and mix it completely

8 add bicorbonate stirr it until it dissolve completely

9 pour the solution in volumetric flask with the help of funnel

10 add water to make final volume upto 100ml

Precautions:-

1-Weight the Ingredients:-

Weight the sodium chloride potassium chloride calcium chloride magnesium chloride sodium bicarbonate sodium phosphate and glucose accurately using a weighing scale. 

2-Dissolve the Ingredients:-

Dissolve the sodium chloride potassium chloride calcium chloride magnesium chloride and glucose in 500 mL of distilled water in a large container or beaker. 

3 -Add Sodium Bicarbonate and Sodium Phosphate:-

Add the sodium bicarbonate and sodium phosphate to the solution and stir until they are fully dissolved.

4-Add Distilled Water:-

Add the remaining 500 mL of distilled water to the solution and stir well.

5-Filter the Solution:-

Filter the solution using a 0.2 μm filter to remove any impurities.

6-Store the Solution:-

Store the Tyrode's solution in a sterile container at 4°C.
