The presence of secretory protein-I (SP-I) or chromogranin A (CGA) in granules isolated from the granular cells of the amphibian urinary bladder epithelium was investigated using ultraimmunohistochemistry. Granules were isolated by cell fractionation using Percoll density gradients. SP-I was isolated and purified from bovine parathyroid glands. Antibodies were raised in rabbits and purified by affinity chromatography. Ultraimmunocytochemistry, employing the avidin-biotin-peroxidase (ABC-complex) procedure, was used to localize SP-I on thin sections of isolated granules. About 27% of the granules from control (-ADH) cells were SP-I+, while 51% of the granules fractionated from hormone treated (+ADH) cells were positive for this protein (p less than 0.0001). Accordingly, granules from ADH-treated cells also showed a significant (p less than 0.0001) increase in total protein.

Small cell lung cancers are neuroendocrine tumours and therefore produce a lot of peptide hormones (calcitonin, ACTH, ADH), as well as the neuropeptide chromogranin A, which are all useful tumour markers. Furthermore, the tumour-associated antigens CEA and TPA, as well as the enzymes neuron specific enolase (NSE) and creatine kinase BB are used as markers in small cell lung cancer. At present, NSE appears to be the best marker for small cell lung cancer; elevated serum NSE levels are found in 65 to 85% of the patients. The serum level of the tumour markers is related to the stage of the tumour. When tumour regression occurs following therapy, elevated pretreatment levels decrease to the normal range. If the marker level increases again, tumour progression is indicated and this can be an early and sensitive sign denoting recurrence. Metastases in the central nervous system can be detected early by marker determination in the cerebrospinal fluid. At present, CEA appears to be the most valuable tumour marker for non-small cell lung cancer, but TPA may also be a useful marker.
