2. Restore the gland or administer a gland extract, and observe the animal. 3. Add a gland or gland extract to a normal animal, and observe the animal for excessive response. 4. Purify gland extracts and isolate the substance. There are many hormones that are secreted from cells that are not part of a discrete gland and therefore not removable without causing problems beyond loss of the hormone. |
