OBJECTIVE: To probe into an new methods preserving parathyroid gland of @entity1 with @entity259 . METHODS: Thirty-six @entity1 with @entity259 that primary treated were random divided into two groups: trial group and control group. Emulsion of activated- @entity505 particles was injected into the thyroid gland of trial group @entity1 . After thirty minutes, central compartment dissection was performed in the all @entity1 . The black stained tissue in the dissection specimen of trial group was separated. Total lymph node, @entity3 lymph node and parathyroid gland in the black stained tissue, and non-black stained tissue in the central compartment dissection specimen of trial group and central compartment dissection specimen of control group were counted respectively. RESULTS: Nineteen and twenty central compartment dissection was performed in trial group and control group respectively. There are 177 lymph nodes included 83 @entity3 lymph nodes in the black-stained tissue of central compartment dissection specimen of trial group. No parathyroid gland was found in the black-stained tissue. Nine lymph nodes included 2 @entity3 lymph nodes and 7 parathyroid glands were found in the non-black stained tissue of central compartment dissection specimen of trial group. There were 124 lymph nodes included 80 @entity3 lymph nodes and 8 parathyroid glands in central compartment dissection specimen of control group. There are statistic difference between the amount of lymph node in black stain tissue and that of control group (t = 0.340, P = 0.003). Rate of staining lymph node were 95.2 percent. CONCLUSIONS: Lymph node of VI group can be stained black by activated @entity505 particles, and parathyroid gland cannot be stained black. Maybe, parathyroid gland can be preserved by removing the black stain lymph node and retaining the non-black stained tissue.
