Zinc is essential to numerous metabolic processes in the organism, multiform symptoms being found especially in deficiencies. In addition to nutritional factors, diseases such as cirrhosis of the liver. Crohn's disease and chronic renal diseases are relevant in this context. In the present work, serum zinc levels were investigated in 109 patients with various chronic liver diseases. The lowest serum zinc concentrations were seen in patients with decompensated hepatic cirrhosis with coma. Patients with decompensated alcoholic cirrhosis had lower zinc levels as subjects with nonalcoholic cirrhosis. None of the groups exhibited a significant change in serum zinc levels during the treatment period. Laboratory data (such as transaminases, thromboplastin time, alkaline phosphatase, total proteins) did not correlate with the serum zinc concentrations. The concentration of plasma ammonia, however, appeared to be inversely related to the serum zinc levels. Thus, patients with coma had maximum ammonia and minimum zinc levels.

Human alkaline phosphatase isozymes--the tissue-unspecific, the intestinal, and the placental alkaline phosphatases--were determined in sera by use of isozyme-specific monoclonal antibodies. The clinical utility of serum determinations of alkaline phosphatase isozymes was evaluated in patients with diseases of the gastrointestinal tract and the liver. No elevations of the different serum isozymes were observed in the intestinal diseases investigated (active Crohn's disease and ulcerative colitis). For non-malignant diseases of the liver the alkaline phosphatase isozymes presented characteristic patterns. Patients with cirrhosis due to hepatocellular diseases had markedly elevated levels of intestinal alkaline phosphatase and moderate serum activities of tissue-unspecific and placental alkaline phosphatases. In patients with liver disease with cholestatic features tissue-unspecific and placental isozyme levels were high, but the intestinal isozyme remained normal, whereas primary biliary cirrhosis was associated with high levels of the tissue-unspecific enzyme and moderate elevations of intestinal and placental alkaline phosphatases. It can be concluded that, in addition to tissue-unspecific alkaline phosphatase, intestinal and placental isozymes contribute to the total alkaline phosphatase activity for patients with liver disease. The results suggest that specific methods for the identification of alkaline phosphatase isozymes could be of value.

Peptide YY has been localized within human ileocolonic endocrine cells and may contribute to the regulation of gastric secretion and gastric emptying in man. Since our previous studies had shown decreased colonic concentrations of peptide YY in the idiopathic inflammatory bowel diseases, a specific radioimmunoassay was used to measure fasting serum concentrations of peptide YY in healthy controls and in patients with adenocarcinoma of the rectum, idiopathic chronic active liver disease and hepatic cirrhosis, ulcerative colitis, and Crohn's disease. In healthy controls and in patients with adenocarcinoma of the rectum, serum concentrations of peptide YY ranged from 50 to 260 pg/ml. Serum concentrations of peptide YY in patients with hepatic cirrhosis ranged from 59 to 717 pg/ml. Serum concentrations of peptide YY in patients with ulcerative colitis were similar to healthy controls. In patients with Crohn's disease, serum concentrations of peptide YY were less than 50 pg/ml in three patients who had had a previous proctocolectomy, and were more than 260 pg/ml in 14 patients who had had previous resection of more than 48 cm of ileum or presently had symptomatic Crohn's disease subsequently requiring surgical resection of a total of more than 75 cm of ileum. These results suggest that most circulating peptide YY is released from the colorectal region. Hepatic cirrhosis, previous ileal resection, and symptomatic Crohn's disease were associated with elevation of fasting serum peptide YY. The mechanism of increased fasting serum peptide YY in patients with Crohn's disease could be the loss of an ileal inhibitory factor or possibly an increased release of colonic peptide YY in response to fat malabsorption. The effect of alteration of serum peptide YY concentrations on the pathophysiology of Crohn's disease is yet unknown.

Nine hundred and ninety nine patients were admitted in our Department (the Third Department of Internal Medicine, School of Medicine, UOEH) during the five years more since the opening date of the University Hospital (July, 9, 1979), and 864 cases in them (86.2%) suffered from the various digestive diseases. Most of the in-patients with digestive diseases in our Department are resident in Kitakyushu city and its suburbs, especially in Yahatanishi-ku, Wakamatsu-ku and Onga county, therefore, it may be possible to investigate the ecological characteristics of the in-patients of our Department in the relation to the outbreak, clinical course and outcome of the digestive diseases. Namely, it may be assumed that the incidence and prevalence of the idiopathic inflammatory bowel disease (IBD) including ulcerative colitis and Crohn's disease are relatively high in this area (Kitakyushu city and its suburbs) as compared with the average of all Japan. Although the true causes of these illness are still unknown, the inclination of haptoglobin phenotypes (HP) which include 2-2, 2-1 & 1-1 type 1-1 strongly suggests to the association with some genetical factors on the high incidence of these diseases (IBD). In this connection, Hp type 1-1 were recognized 4 in 11 cases (36.4%) with ulcerative colitis, and 3 in 7 cases (42.9%) with Crohn's disease in our Department whereas only 3-5% in normal controls. Secondly, the patients with carcinoma of the biliary tree (bile duct and gall bladder) are relatively more, namely, 17 cases of bile duct cancer and 3 cases of gall bladder cancer were admitted in our Department during this term. It is interesting to note that hepatohilar type of the bile duct cancer was observed comparatively high (4 in 17 cases, 52.9%) in the past five years-more although the etiology is unknown. Finally, several characteristics in liver diseases particularly in viral hepatitis were illustrated in this study, namely, the ratio of transient HBV infection to whole (transient and persistent) HBV infection in the patients with acute viral hepatitis (due to HBV) is high (80.9%), HBeAg positivity is high in chronic B-hepatitis (44.9%), the ratio of alcoholic cirrhosis to whole liver cirrhosis is relatively high (34.9%) and HBsAg positivity is lower in liver cirrhosis due to non-alcoholic origin (mainly due to hepatitis virus) than the average of this country, and also, hepatocellular carcinoma (HCC) without liver cirrhosis is higher (23.0%) than the average of whole Japan (less than 15%) statistically.

Endoscopic retrograde pancreatograms were examined in a consecutive series of patients with cholestatic disease caused either by primary biliary cirrhosis (PBC) (35 patients) or by sclerosing cholangitis (SC) (38 patients). The pancreatic ducts were abnormal in three of the patients with PBC but in none with SC. Gallstone disease occurred concomitantly in the two patients with most advanced pancreatic involvement. The liver disease was classified as advanced PBC in 11 of the 35 patients. Symptoms of hepatobiliary disease were scarce in most SC patients. Eight of the 38 patients had histologically verified biliary cirrhosis. SC was associated with extensive, but most often inactive or mild, colitis in 97% (ulcerative colitis in 34 and Crohn's disease in 3 patients). Three of these patients had concomitant cholangiocarcinoma.

The estimation of vitamin A in serum of patients suffering from different diseases (M. Crohn, Hypothyroidism, Hyperthyroidism, Liver cirrhosis, Renal insufficiency, Carcinoma of Prostate, ENT-Carcinomas) and healthy controls by means of a recent developed method (HPLC) is reported. Decreased and increased vitamin A serum levels had been reported in literature during different diseases but we could not reveal identical results in all cases. Significantly lowered values were only estimated in patients suffering from liver cirrhosis whereas increased vitamin A serum levels were determined during renal insufficiency. In hypo- or hyperthyroidism there was no difference from healthy persons. In patients with Crohn's disease the distribution of vitamin A concentrations in serum was bimodal, probably depending on extension and localization of the process. Patients with carcinoma of the prostate had only minor deviations from the normal value, whereas patients with tumors of the larynx had in part very low vitamin A concentrations with a bimodal distribution. Causes for the deviations and consequences for the assessment of the vitamin A status of patients under intravenous alimentation are discussed.

Plasma fatty acids and lipid peroxidation were studied in human atherosclerosis. Analysis of fatty acids in 16 controls and 32 hyperlipidemic patients showed, in the latter, a decrease in saturated fatty acids, especially palmitic and stearic acids, and an increase in unsaturated fatty acids, especially arachidonic acid. Compared to hyperlipidemic patients without arterial injury, patients with arterial injury exhibit a significant increase in malonaldehyde (MDA). In the former, MDA concentrations are significantly increased compared to controls. Therefore, peroxidation of unsaturated fatty acids may have a deleterious effect on arteries in atheroma, through the release of toxic endoperoxydes and the metabolization of arachidonic acid into thromboxane, which is a platelet aggregator. Lipid peroxidation can also be demonstrated in other diseases: we found very high MDA concentration in 11 alcoholic patients (alcoholic hepatitis, cirrhosis) and 6 patients with inflammatory conditions such as Crohn disease.

It has been established rather surely that patients with chronic liver disease, Crohn's disease, chronic pancreatis and celiac disease are deficient in zinc and vitamin A. A large number of clinical symptoms can be caused by these deficiencies, due to the fact that these compounds have numerous functions. Zinc deficiency in liver cirrhosis is probably caused by portosystemic shunting, whereas in Crohn's disease abnormalities of protein metabolism are suggested as etiologic factor. Vitamin A deficiency can be considered as a consequence of disturbed zinc metabolism. Some studies in appropriate patients receiving substitution therapy with zinc and/or vitamin A had positive results. However, the necessity of substitution in the diseases mentioned has not yet been conclusively demonstrated.

Zinc is essential for many metabolic and enzymatic functions in man. Deficiency of zinc in man has now been recognized to occur not only as a result of nutritional factors, but also in various disease states, including malabsorption syndromes, acrodermatitis enteropathica, Crohn's disease, alcoholism and cirrhosis of the liver. The deficiency state in human subjects exists as a spectrum extending from mild to severe degree. The clinical manifestations of mild zinc deficiency include oligospermia, weight loss and hyperammonaemia. Moderate zinc deficiency is characterized clinically by growth retardation, hypogonadism in males, skin changes, poor appetite, mental lethargy, delayed wound healing, taste abnormalities and abnormal dark adaptation. In severe zinc deficiency states, bullous-pustular dermatitis, alopecia, diarrhoea, emotional disorders, weight loss, intercurrent infections, hypogonadism in males and, if unrecognized, death have been observed. Zinc is needed for the functions of over 100 enzymes. It is essential for DNA, RNA and protein synthesis and, as such, is important for cell division. Zinc is an inducer of mRNA of metallothionein, a protein which may have an important role in the regulation of intestinal zinc absorption. Zinc has a specific effect on testes in animals and man. Recent reports indicate that in human subjects thymopoietin may be zinc dependent and in animal studies somatomedin may be affected adversely due to dietary zinc restriction. Zinc plays an important role in the protection of cell membrane integrity and may be protective against free radical injury. Zinc is known to compete with cadmium, lead, copper, iron and calcium for similar binding sites. In the future, a potential use of zinc may be to alleviate toxic effects of cadmium and lead in human subjects. Recent evidence suggests that thymic-dependent lymphocytes (T cells are zinc dependent. T-helper and suppressor cells, T-effector cells and T-natural killer cells appear to be zinc dependent. Zinc is also essential for some of the neutrophil functions. Thus, it appears that zinc may play an important role in immunity. One may suggest that some of the clinical features of cirrhosis of the liver, such as testicular atrophy, loss of body hair, night blindness, poor wound healing, poor appetite, susceptibility to infections and enhanced sensitivity to drugs, may be related to conditioned deficiency of zinc, future studies are required to determine whether or not zinc supplementation is beneficial to these patients.

In several gastroenterological diseases andrological anomalies have become known. From this point of view up to now the liver cirrhosis has been examined most frequently. In patients with cirrhosis apparently the two functions of the testicles are disturbed. On the one hand, a decreased or missing fertility is to be assumed, on the other hand, a cirrhosis does not always exclude the procreative capacity. The hormone analyses plead for the fact that the hypogonadism might rather be conditioned testicularly, in which case the direct toxicity of alcohol may be of importance. In haemochromatosis the hypogonadism develops by a combined mechanism. The cystic fibrosis of the pancreas is practically always associated with a male infertility. In Crohn's disease a disturbance of the spermatogenesis is observed. Even the salazo-sulphapyridine therapy is accompanied by unfavourable influences on the spermiogramme. Cimetidine used in the ulcer therapy shows a certain antiandrogenic effect and after a longer time may evoke impotence and other undesirable andrological side-effects which we, however, did not realize in 4 weeks treatment periods.
