Practical work of students
The task №1.Study the effect of high temperature on osmotic resistance of rabbit’s erythrocytes.
Technique: 0.5 ml of blood from a regional vein of an ear of the healthy rabbit was taken into a test tube. 0.02 ml of blood were placed into 4 test tubes, with 5 ml of NaCl solution of 0.3 %, 0.45 %, 0.65 %, 0.85 % ).
The rest blood was incubated within 5 minutes in a water bath with water temperature of 500С. After that, 0,02 ml of the heated blood was placed into other 4 test tubes with the same concentrations of NaCl. After 10-15 minutes of exposure intensity of the color is visually compared. Analyze the results of an experiment using the table, make the conclusion.
The protocol of the experiment

The task № 2. Analyze the effects of ethanol on rabbit’s erythrocytes.
Technique: 5 ml. Ringer's solution is placed into 5 centrifuge tubes. Then the ingredients according to the protocol specified in the table below are added.
| Tube 1 (control) | Tube 2 | Tube 3 | Tube 4 | Tube 5 |
| 5 ml. Ringer's solution + 0,02 ml blood | 5 ml. Ringer's solution + 0,5 ml 30% Н2О2 + 0,02 ml blood | 5 ml. Ringer's solution + a few grains of powder detergent + 0,02ml blood | 5 ml. Ringer's solution + 0,5 мл 0,1N HCl + 0,02 ml blood | 5 ml. 0,5% solution of NaCl + 0,02 ml blood |
