Motilin, normally present in a specific cell type in the upper small intestine, is believed to have a physiologic role in initiating the interdigestive migrating motor complex. Motilin may play a pathophysiologic role in the diarrhea in the irritable bowel syndrome, the dumping syndrome, chronic liver disease, and chronic renal failure. Furthermore, increased frequency of bowel movements is an important symptom in patients with the carcinoid syndrome. We have studied 73 patients with metastatic carcinoid tumors with regard to stool frequency and plasma concentration of motilin and neuropeptide K (NPK) and diurnal urinary excretion of 5-hydroxyindoleacetic acid (5-HIAA). Thirty-eight (52%) of the 73 patients had elevated (greater than 126 pmol/l) plasma concentrations of motilin, whereas 59 (81%) of the patients had diarrhea. The increased frequency of bowel motions correlated significantly (p less than 0.01) with the plasma concentrations of motilin, whereas no significant correlation with 5-HIAA and NPK was found. High-performance liquid chromatography of plasma extracts showed a single component eluting in the position of synthetic porcine motilin. However, extracts from five carcinoid tumors did not contain any significant levels of motilin. Carcinoid tumors are known to contain and secrete several biologically active substances such as serotonin, histamine, prostaglandins, and tachykinins, which are likely to cause disturbances of intestinal secretion and motility, which in turn might release motilin from the motilin-containing cells of the small intestine. The increased motilin levels might then participate in a vicious diarrhea circle together with the other agents.

Insulin-like growth factor II is secreted primarily by the liver and is reported to be transcribed in many primary hepatocellular carcinoma (PHC) cell lines. We have studied diagnostic significance of serum IGF-II in chronic liver diseases using specific enzyme immunoassay. Serum IGF-II levels (mean +/- SE) were decreased in chronic hepatitis (538 +/- 51 ng/ml; N = 29), liver cirrhosis (427 +/- 45; 50) and PHC (260 +/- 41; 17) compared to controls (830 +/- 49; 57). Serum IGF-II was not different from controls in any of nonhepatic diseases such as diabetes (1032 +/- 97; 19) pancreatic cancer (1413 +/- 282; 8), chronic pancreatitis (999 +/- 126; 17), peptic ulcer (1186 +/- 43; 11), irritable bowel syndrome (1002 +/- 109; 12), gastrointestinal tract cancer (1250 +/- 216; 21) and chronic renal failure (733 +/- 135; 14). In liver diseases serum IGF-II showed a significant correlation with liver function test (negative with retention of indocyanine green and total bile acids; positive with albumin, thrombo-test, and cholinesterase). These results suggest that serum IGF-II reflects a reduced production of IGF-II in the liver and that it can be an index for the residual capacity of liver function.

Diagnostic significance of a simple and rapid screening procedure for determining the relative amounts of pancreatic and salivary isoamylase using an amylase inhibitor was evaluated in 242 subjects (controls 84, acute pancreatitis nine, chronic pancreatitis 28, pancreatic cancer 14, peptic ulcer 25, liver cirrhosis 15, cholelithiasis 24, irritable colon syndrome 13, diabetes mellitus 13, mumps seven, and chronic renal failure 10). Electrophoretically separated isoamylases of saliva and pure pancreatic juice were all inhibited at similar degrees to the corresponding unfractionated amylases. Total amylase and pancreatic isoamylase were elevated in all nine patients with acute pancreatitis. Pancreatic isoamylase was decreased in 12 of 28 patients (43%) with chronic pancreatitis and increased in nine of 14 patients (64%) with pancreatic cancer. The mean pancreatic isoamylase activity in the patients with acute pancreatitis was significantly higher (p less than 0.01), while that of chronic pancreatitis was significantly lower (p less than 0.05) when compared with controls. The inhibition method offers simple, rapid, and specific analysis of serum isoamylase for the differential diagnosis of hyperamylasemia in cases of emergency.

Shankha Prakshalana is an easy and effective technique for cleansing the gastrointestinal canal, thereby removing all the autointoxicants present in the alimentary canal. Moreover, it is a very economical procedure which can be performed by the patients at his own residence. The role of Shankha Prakshalana from our own experience is very effective in overcoming the irritable bowel syndrome. Shankha Prakshalana may also be given to the patients of anxiety neurosis with satisfactory results. Its role in the treatment of renal disorder is encouraging in early cases only. However, in the second and third degree chronic renal failure cases its role is yet to be established and needs further investigation. Similarly, in the case of thyrotoxicosis no conclusive evidence could be observed due to very limited number of cases.
