Question
me Time from phenol to to excretion in urine was: 0.02 injection no ph in red in [Conclusion and Discussionl l. How did the volume of urine change when 20 ml saline solution was injected into the rabbit vein? Please describe the possible mechanisms. 2. What happened to urine volume when 20% glucose solution was injected into the vein? Please describe the possible mechanisms. 3. What is the effect and mechanism of furosemide on urine volume? 4. What is the effect and mechanism of pituitrin on urine volume? 5. What is the effect and mechanism of norepinephrine on urine volume?Explanation / Answer
Answer
Conclusion and discussion
(1) Saline solution: Inject 20 ml saline solution into the ear vein quickly by moving
the syringe on the ear. Record the maximum value of urine volume as well as SP/DP
from the right panel of the recorder.
(2) Glucose solution: Inject 5 ml 20% glucose into the ear vein by moving the
syringe on the ear. Record the maximum value of urine volume as well as SP/DP from
the right panel of the recorder.
(3) Furosemide: Inject 15 mg furosemide into the ear vein by moving the syringe on
the ear. Record the maximum value of urine volume as well as SP/DP. (
4) Pituitrin: Inject 2 unit pituitrin into the ear vein by moving the syringe on the ear.
Record the minimum value of urine volume as well as SP/DP.
(5) NE(norepinephrine) : inject 0.3 ml NE into the ear vein by moving the syringe on the ear. Record the minimum value of urine volume as well as SP/Dp.
Discussions
1. In certain liver disease such as biliary obstruction or hepatitis, excess bilirubin can build up in the blood and is climinated in urine. The presence of bilirubin in urine is an early indicator of liver disease and can occur before clinical symptoms such as jaundice develop.
2. Urine glucose is no longer recommended for the diagnosis of diabetes nor to follow those with diabetes. There is a very poor correlation between serum glucose and glucose in the urine. For example: you may have 2+ urine glucose with a serum glucose of 70 mg/dL (US Units) or 3.9 mmol/L (International Units) and you may have 0 urine glucose with a markedly elevated serum glucose.
3. This test is comparing the density of urine to the density of distilled water, the latter of which is set at1.000. So water has a specific gravity of 1.000, but because urine is mainly water with some additional stuff like electrolytes dissolved with in it thereby increasing in its density compared to pure water, USG can never be less than 1.000.
