Plasma and 24-h urinary adenosine 3':5'-monophosphate (cyclic AMP) and guanosine 3':5'-monophosphate (cyclic GMP) were measured by radioimmunoassay in 12 normal subjects, 33 patients with six types of non-neoplastic disease (cholelithiasis, peptic ulcer, coronary heart disease, hypertension, regional ileitis, and cirrhosis), and 34 patients with five types of disseminated neoplastic disease (acute myelocytic leukemia; Hodgkin's disease; and metastatic cancer of the lung, colon, and breast). In patients with non-neoplastic disease, cyclic nucleotide values in plasma and urine did not differ significantly (P greater than 0.05) from those in normal subjects. In patients with disseminated cancer, cyclic AMP values in plasma and urine likewise did not differ significantly from those in normal subjects. Plasma cyclic GMP, in contrast, was significantly elevated in all five types of cancer patients, and urinary cyclic GMP was significantly elevated (five times the normal mean) in patients with acute myelogenous leukemia and Hodgkin's disease.

The aims of this review are: 1. to provide a bibliography of the publications that have used the corrosion casting technique; 2. to describe the advantages and limitations of the methodology; 3. to illustrate possible applications in the field of medicine, and 4. to highlight the significance of this method in the teaching of medical students. Thus, this paper is primarily focused on the scanning electron microscopical examination of vascular corrosion casts. The unsurpassed three-dimensionality of the corrosion casting technique compared to any other means stands out in particular. This can be especially useful when complex vascular-anatomical relationships are present. This applies not only to the portrayal of the modes of branching and varying vascular densities but also to regulatory arrangements, such as sphincters and arteriovenous anastomoses. Between 1966 and 1990, a total of 549 publications were found in the Medline literature data bank, containing the key words "corrosion casting", "microvascular cast", or "vascular cast" (as of August, 1990). Of those publications, most dealt with applications to experimental animals. By contrast, only 142 reports were mainly or partially concerned with human investigational material. The normal vascular system of nearly all organs, insofar as this is of direct medical relevance, has been largely resolved. In our opinion, one of the most important potential applications of the corrosion casting technique lies in the investigation of gastrointestinal, renal or hepatic ailments, which coincide with the reconstruction or rarefication of the vascular bed, e.g., in ulcers, ileitis terminalis, colitis ulcerosa, cirrhosis or glomerulonephritis.

Of 72 patients who underwent jejunoileal bypass because of morbid obesity, 69 could be evaluated with special reference to long-term (median 11 years) results. One of the other three had fatal anastomotic leakage, one underwent resection and reversal of shunt because of postoperative gangrene in the bypassed segment, and one died of sepsis and liver failure following cholecystectomy 6 months after bypass. The median body mass index (kg/m2) fell from 45.4 preoperatively to 33.2 after 16 years. Shunt-related complications in early and late follow-up were diarrhoea (n = 15), anal/perianal disorders (15), arthralgia (15), urinary calculi (16), cholelithiasis (5), severe flatulence (7), liver cirrhosis (5), intestinal tuberculosis (1), ileitis (1), severe electrolyte disturbance (4), hypomagnesaemia (22), hypokalaemia (8), and deficiency of vitamin B12 (24), iron (24) and folate (17). Although jejunal bypass effectively reduces weight, the patients are at continuous risk of many complications. However, the improvement in quality of life should not be underestimated.

The plasma and 24-hr urinary levels of cyclic adenosine 3':5'-monophosphate and of cyclic guanosine 3':5'-monophosphate (cGMP) were determined for 19 healthy normal patients, 54 patients with six types of nonneoplastic diseases (cholelithiasis, peptic ulcer, coronary heart disease, hypertension, regional ileitis, and cirrhosis), and 54 patients with five types of neoplastic disease (cancers of the lung, colon, and breast, acute myelocyte leukemia, and Hodgkin's disease). The cyclic adenosine 3':5'-monophosphate levels of urine and plasma in normal subjects, in noncancer subjects, and in cancer subjects did not differ significantly. The cGMP levels in the noncancer group were similarly unchanged from those in the normal group. However, mean cGMP levels in the urine and plasma of patients with neoplastic diseases were, respectively, 2- and 3-fold greater than the normal values (p less than 0.005 for urine and p less than 0.05 for plasma). Pharmacokinetic studies with [3H]cGMP in nine healthy controls and 15 patients with neoplasia showed that the mean production rate of this nucleotide in patients with metastatic cancer was elevated when compared to normal patients, but many values fell within the normal range. In acute leukemia, the production rate was seven times normal, with four of five patients having values clearly outside the normal range. The plasma clearance rate in patients with neoplasia was not decreased when compared to that in normal patients. It is proposed that an increased production rate, rather than any change in plasma clearance, accounts for the increased levels of cGMP in the plasma and urine of some patients with neoplastic disease.
