In order to investigate experimented effects of Indongdeung Jigolpi-Tang, which is applied to Soyangin, to diabetes, the measurement, comparision and observation made on the contents of volumes of blood glucose, total cholesterol, triglyceride, phospholipid, total protein and electrolyte K+, Na+) in blood serum by giving a high blood glucose, induced by streptozotocin, to hyper- glycemic rats, dosing the cooked liquid of I.J.T., and following conclusion was attained.
1. The volume of glucose urine, induced by streptozotocin to hyperglycemic rats, was shown an increase in comparision to a normal flock when 12.50ml/kg of I.J.T. dosed to the rats and checked after two and four weeks and thereby, a sinificant reduction in the volume of blood glucose was made.
2. The volume of total cholesterol of blood serum in the diabetic rats, induced by streptozotocin, was increased in comparision to the normal flock, and in the fouth week of dosing 1.25ml/kg of I.J.T., a significant reduction of total cholesterol volum was shown in the blood serum.
3. The volume of triglyceride in the blood serum of the diabetic rats, induced by the streptozotocin, was increased in comparision to the normal flock, and with dosing 1.25ml/kg and 12.50ml/kg of I.J.T., a significant reduction of triglyceride volium was shwon in the blood serum after second and fourth week.
4. The volume of phospholipid in the blood serum of the diabetic rats, induced by the streptozotocin, was somewhat reduced in comparision to the normal flock, and with dosing 1.25ml/kg of I.J.T., a significant reduction of phospholipid volium in the blood serum was shown after first and second week.
5. The volume of total protein in the blood serum of the diabetic rats, induced by the streptozotocin, was somewhat reduced in comparison to the normal flock however, with dosing the I.J.T., no significant change on the volium of total protein was made in the blood serum.
6. The volume of potassium in the blood serum of the diabetic rats, induced by the streptozotocin, was increased in comparision to the normal flock however, with dosing the I.J.T., no significant change of potassium content was made in the blood serum.
7. The volume of sodium in the blood serum of the diabetic rats, induced by the streptozotocin, was somewhat reduced in comparison to the normal flock, and with dosing 12.50ml/kg of the I.J.T., a significant increase was shown in the blood serum after first week.
Soyangin, accompanying with a middle and upper heat, the I.J.T. - that has a merits of cleaning up fever, solving fever, solving poison, solving thirst and restoring exhaustion - can be proved that it has a blood sugar reduction effect and it is considered that it can be meritorious for strengthening vitality, further, many other exhausting diseases, and can actively used for the cases such as thirst causing disease and a disease that causes an abnormal food hunger, thirst causing and frequent going to pass urine, in particular.
