17 patients with severe hyponatraemia (none had cardiac failure or had lately had an operation) all had excessively high plasma-antidiuretic hormone (A.D.H.). Only 13 had features typical of the syndrome of inappropriate secretion of A.D.H. (S.I.A.D.H.). Plasma-A.D.H. was not related to either plasma-sodium or diagnosis. There were as many patients with chest infection as with carcinoma of the lung. Plasma-sodium and plasma-A.D.H. returned rapidly towards normal in the patients with chest infection or volume depletion but these concentrations corrected much more slowly in patients with carcinoma of the lung. The increase in plasma-sodium in patients with chest infection was too rapid to be produced by water-deprivation treatment and was due to return of plasma-A.D.H. to normal. The term S.I.A.D.H. implies an understanding of pathophysiology that does not exist. As a diagnosis it does not help in management or prognosis. A simpler, more descriptive terminology such as "hyponatraemia with carcinoma of the lung" would be more useful and less confusing in the clinical situation.

3 cases of inappropriate vasopressin secretion during one case of anaplastic carcinoma of the lung, one case of carcinoma of the prostate with bony metastases and one case of acute intermittent porphyria are presented. The plasma levels of vasopressin, measured by radioimmunoassay were high. Treatment with demeclocycline was attempted in one case. The clearance of free water was positive but the treatment was poorly tolerated by the digestive tract.

A novel nitrosourea derivative, methyl-6-[[[(2-chloroethyl)nitrosoamino]carbonyl]-amino]-6-deoxy-alpha-D-glucopyranoside (MCNU), is a water-soluble compound in which a methoxyl group is attached to the C-1 position and an N-(2-chloroethyl)-N-nitrosoureido group is attached to the C-6 position of the glucose moiety. MCNU exhibited a marked life-prolongation or growth-inhibitory effect against mouse L1210 leukemia, adenocarcinoma 755, Nakahara-Fukuoka sarcoma, Lewis lung carcinoma, and B16 melanoma. Ip, oral, or iv administration of MCNU was markedly effective against L1210 leukemia, and the therapeutic ratio by ip administration was larger than that of chlorozotocin or CCNU. The life-prolongation effect of MCNU against established Lewis lung carcinoma was similar to that of methyl-CCNU. The bone marrow toxicity of MCNU was less than that of CCNU but considerably more than that of chlorozotocin.

The carcinogenic activity of orally administered N-bis(2-hydroxypropyl)-nitrosamine (DHPN) in male Wistar rats was evaluated with respect to its dose. DHPN was administered at two doses, 100 ppm and 500 ppm, in the drinking water to rats for 25 to 52 weeks. Tumors developed in the lung, liver, and thyroid of rats receiving 100 ppm DHPN and in the lung, liver thyroid, esophagus, kidney, and urinary bladder of rats receiving 500 ppm DHPN. The principal target organ was the lung in rats receiving either 100 or 500 ppm DHPN, indicating that the carcinogenic action of these doses of DHPN was similar to that of higher doses previously reported. Histologically, the tumors were adenoma, adenocarcinoma, squamous cell carcinoma, and combined carcinoma of the lung, hepatocellular carcinoma and hemangioma of the liver, adenoma and adenocarcinoma of the thyroid, squamous cell papilloma and carcinoma of the esophagus, renal cell and transitional carcinoma of the kidney, and transitional cell carcinoma of the urinary bladder. No pancreatic tumors were observed.

This paper reviews the problem of radiation-induced carcinoma of the lung in the fluorspar mines of Newfoundland. Seventy-eight workers have died from this disease since commercial operation commenced in 1933. In 1959 the source of the radiation was identified as radon, and its daughter nucleotides present as contaminants in water seeping into the mines. Heavy smoking is probably a synergistic cocarcinogen. The histology in this group of patients with radiation-induced lung cancers is unusual, since squamous cell carcinoma accounts for 90 percent of all cases. There have been four patients with second primary lung cancers. Radical radiotherapy has been the primary mode of treatment based on the reluctance of the miners to undergo operation. Surprisingly good results have been obtained, with an average survival time of 34 months after treatment. Institution of improved ventilation has reduced radiation to safe levels, but an estimated 120 miners from the pre-1960 era are still at risk.

California has 12% of the U.S. population. In 1991, the newly diagnosed cancer cases in California represented 10% of all new cancer cases in the country, and the yearly toll was 10% of all cancer deaths. Relative to all new cancer cases in the U.S., California had 10, 9.8, 9.8, and 9.3% of breast, lung, prostate, and colorectal cancers, respectively. Because of its large population and cancer incidence, the epidemiology of cancer in California is of particular interest. Epidemiological factors reviewed in this article include ethnicity, lifestyle, occupation, and environmental conditions. Ethnic factors: There is an increased incidence of cervical and gallbladder cancer among Hispanic women, and of stomach cancer in Hispanic men and women. In U.S.-born Chinese men, the most prevalent cancers are those of the lung and colon, which is also seen in American white men. In U.S.-born Chinese women, there is an upward displacement of breast cancer incidence. In U.S.-born Japanese men and women, the mortality rate is closer to that of American whites. Life-style: Members of the Mormon Church and Seventh-Day Adventists have only 50% of the U.S. standardized mortality rate for cancer associated with smoking. Increased coffee consumption has been found to be associated with increased occurrence of colon and bladder cancer; alcohol use has been reported to have a positive association with colorectal cancer. The large AIDS population in San Francisco has a 144-fold odds ratio of Kaposi's sarcoma and a fivefold odds ratio of lymphoma when compared with the general U.S. population. Occupational factors: An increased incidence of mesothelioma in asbestos workers, of gastric cancer, skin cancer, and lymphoma in men working in dusty environments, and of astrocytoma in individuals with prolonged exposure to low-frequency electric and magnetic fields has been recorded. Environmental factors: The drinking-water pool in northern California is contaminated with asbestos of the serpentine type, which is associated with mesothelioma of the peritoneum and carcinoma of the lung, gallbladder, and pancreas. Petrochemical fumes in the heavily industrialized San Francisco Bay area have not been associated with an increased occurrence of cancer. No significant incidence in cancer has been noted in the counties surrounding the nuclear power plant at San Onofre during 18 years of close observation.

The effects of two new Ru(III) complexes, [mer-RuCl3(DMSO)2Im] degrees and Na[trans-RuCl4(DMSO)Im], were investigated on primary tumor growth and on the survival time using three solid metastasizing tumors of the mouse: Lewis lung carcinoma, B16 melanoma and MCa mammary carcinoma. Na[trans-RuCl4(DMSO)Im] appears to be the most promising compound, in that: (1) it is soluble in water and therefore easy to handle in comparison with the neutral species [mer-RuCl3(DMSO)2Im]degrees or to the already described BBR2382; (2) similarly to cisplatin, though at a lower level, it reduces tumor growth in its primary site in each tumor model employed; (3) unlike cisplatin, it increases the life span of tumor-bearing hosts in all tumors used, independently of the effects on primary tumor growth; and (4) it is also effective in reducing spontaneous metastasis formation when the effects on primary tumor growth are completely absent. Dimethylsulfoxide (DMSO), used for solubilizing poorly water-soluble compounds (i.e. [mer-RuCl3(DMSO)2Im]degrees) or for stabilizing the compound in the solution before injection (i.e. Na[trans-RuCl4(DMSO)Im]), reduces the anti-tumor potency. Conversely, the antitumor effects of Na[trans-RuCl4(DMSO)Im] are more pronounced in mice hydrated with isotonic saline. We conclude that Na[trans-RuCl4(DMSO)Im] is a good candidate for further investigations aimed at ascertaining the mechanism of the anti-metastatic activity and of the positive effects on survival time of mice bearing solid metastasizing tumors.

Protein from hog which is recognized by human monoclonal antibody (HB4C5), generated from a patient with large cell lung carcinoma, was identified as carboxypeptidase A by comparison of the protein with carboxypeptidase A in enzymatic activity, immunologic reactivity, and amino acid sequence. Carboxypeptidase A activity was also found in human cancer tissue, and purified antigen from cancer tissue recognized by the antibody HB4C5 was reacted with rabbit anti-carboxypeptidase A serum, indicating that carboxypeptidase A is an antigen of HB4C5. Since large amounts of carboxypeptidase A can be obtained from porcine sources, a simple method for its purification was established. The fraction which was most reactive with HB4C5 was obtained from acetone powder of porcine pancreas by successive applications of water extraction, ammonium sulfate precipitation, trypsin treatment, and Mono Q column chromatography. Its apparent molecular weight was 40,000, according to SDS polyacrylamide gel electrophoresis. When the reactivity of IgG in sera with the purified carboxypeptidase A was measured, the detection rates for lung, ovary, larynx, uterus, and liver cancer were more than 50%, while the rates for stomach and breast cancer were around 30%, and pancreatic cancer, benign diseases, and normal controls were minimally detected.

Excellent water suppression is required to perform in vivo 1H spectroscopic experiments. However water suppression is difficult due to both B0 and RF inhomogeneities. These inhomogeneities are particularly troublesome in spectroscopic imaging experiments where water suppression is required throughout some large region of interest. In this paper, we propose the use of spectral-spatial excitation pulses for such experiments. These two-dimensional pulses are shown to provide water suppression that is insensitive to a range of B0 and RF variations while simultaneously providing spatial localization. Experimental results including images (with voxel volumes ranging from 3.4 to 1.5 cc) of various brain metabolites from both a normal volunteer and a patient with a metastatic lung carcinoma are presented.

N-Acetylchitohexaose, a water-soluble oligosaccharide was found to display a significant antimetastatic effect against Lewis lung carcinoma (LLC) transplanted into C57BL/6 mice, giving rise to a 40-50% inhibition ratio of pulmonary metastasis when administered intravenously (1 mg/kg) on day 6 after the tumor implantation (5 x 10(5) cells/mouse). It was also revealed that this hexaose had a significant growth-inhibitory effect against the local tumor of the same carcinoma (a 20-30% inhibition ratio), showing an enhancing effect on concomitant immunity in local tumor-resected mice. This oligosaccharide was also shown to enhance the tumoricidal effect of splenic T lymphocytes against LLC and P-815 mastocytoma cells and to increase the natural killer activity of splenic T lymphocytes, assayed with YAC-1 cells as the target.
