Liver function tests were performed in severe and mild diabetic rats and under the influence of ATP. In mild diabetics the serum cholesterol was significantly increased, while in severe diabetes the serum cholesterol was significantly lower than in mild diabetes. The decreased serum cholesterol in severe diabetes may be an indication for the development of fatty liver. The serum alkaline phosphatase and serum bilirubin were significantly increased in both the severe and mild diabetic states, while the thymol turbidity test was insignificantly changed in both states of diabetes. Serum albumin was significantly decreased in 10 days mild diabetes, while it was insignificantly changed in 48 hrs severe diabetic animals. The effect of ATP was investigated in mild diabetes. ATP resulted in a significant increase in serum albumin and a decrease in total globulins with the resultant increase in A/G ratio. The serum alkaline phosphatase exhibited a significant reduction under the influence of ATP. The elevated cholesterol of mild diabetic rats remained significantly elevated and was not reduced by ATP, though the fat content of the liver showed a significant reduction. This may be due to more rapid mobilisation of fat from the liver under the influence of ATP. ATP showed no significant effect on serum bilirubin and thymol turbidity test. the histopathological examination of the liver revealed that administration of ATP to alloxan diabetic rats had a beneficial effect. It resulted in disappearrance of the fat globules from the liver cells.

Procedures developed for in vitro pellicle formation in intact enamel proved useful for relating qualitiative characteristics of dental pellicle to a number of factors. Coronal surfaces of extracted human molars from experimental and control groups were pumiced, sterilized, and incubated for two hours at 37 C in parotid saliva and distilled water, respectively. Pellicle proteins were desorbed sequentially with water and 0.2 M sodium phosphate, with a pH of 7.0. Polyacrylamide disc electrophoresis of the desorbates yielded distinct patterns, indicating selective adsorption of proteins from saliva, varying affinity to enamel, and the presence of proteins not acquired in vitro from saliva. Certain pellicle components, including amylase and IgA, showed a relatively weak affinity for enamel and were eluted in part by water; other proteins were desorbed only by phosphate buffer. Anionic electropherograms of the phosphate desorbates showed an increase in the two most anodic proteins relative to corresponding salivary bands. An intense anodic protein and two minor bands were eluted by water or buffer from the surface of control as well as experimental teeth but not from teeth coated with sealants. Serum albumin and alkaline phosphatase were identified as components of the extra-salivary material. Further investigation of the sources and functions of the constituents of the protein layer generally considered as "acquired" dental pellicle appears warranted.

Venous blood samples were collected monthly from 60 male and 60 female Sinclair (S-1) miniature swine from 1 through 36 months of age. Serum total protein concentration increased linearly from 1 through 10 months of age and remained stable thereafter with no sex related difference. Serum albumin concentration decreased from 1 through 3 months, increased from 3 through 8 months and decreased from 14 through 36 months. From 2 through 36 months, serum alpha-globulin concentration decreased; whereas, serum beta-globulin concentration increased. Serum gamma-globulin concentration increased markedly from 1 through 3 months and continued to increase through 36 months of age. From 10 through 36 months, males had a greater mean serum gamma-globulin concentration than did females. Serum total globulin concentration increased most rapidly from 1 through 3 months, less rapidly from 3 through 18 months and remained stable thereafter. Serum albumin/globulin ratio decreased sharply from 1 through 3 months and continued to decrease from 6 through 36 months with females having a greater mean concentration than males. Serum glutamic-oxaloacetic transaminase activity decreased from 1 through 30 months with males having a greater mean activity than females from 7 through 36 months of age. Serum alkaline phosphatase activity decreased from 1 through 36 months of age with no sex related difference. Serum lactic dehydrogenase activity decreased from 1 through 30 months with females having a greater mean activity than males from 24 through 36 months of age.

Twelve patients with primary biliary cirrhosis (PBC), stages I to III, received long-term therapy with a combination of 600 mg ursodeoxycholic acid (UDCA) and 1 mg colchicine given daily for more than 2 years. Drug toxicity was mild; one patient experienced diarrhoea that was probably due to colchicine. Serum levels of bilirubin, alkaline phosphatase (ALPase), gamma-glutamyl transpeptidase and alanine aminotransferase decreased by more than 50% of the initial values. Serum albumin and cholesterol levels also improved, but immunoglobulins and anti-mitochondrial antibody titre did not change. Histologic features in the eight patients who received serial liver biopsies before and 2 years after the beginning of treatment were evaluated. Piecemeal necrosis and portal inflammation were improved, but there was no change in portal fibrosis. Patients were divided into two groups; the first received both drugs from the outset, and the second group were started on UDCA for 3 months followed by the addition of colchicine. After 3 months, the improvement in serum bilirubin and ALPase in the first group was greater than in the second. However, in the second group, the ALPase levels had decreased significantly when measured at 6 and 9 months after the treatment compared with the levels at 3 months. These findings suggest that UDCA and colchicine may have a synergistic effect. This combination therapy appears to be safe and effective, both clinically and histologically, for treating PBC.

Nine women with symptomatic precirrhotic primary biliary cirrhosis have been treated with oral pulse methotrexate, 15 mg/wk, for 12-34 months. Three women had pruritus, two fatigue, and four pruritus and fatigue. Itching disappeared and fatigue lessened or disappeared in all within 4-11 months after starting methotrexate. All who itched were able to discontinue cholestyramine (five) or antihistamines (two). Biochemical tests of liver function improved in all patients and then worsened in three when methotrexate was discontinued or the dose lowered. Mean serum alkaline phosphatase decreased from 471 to 171 U/L (P less than 0.01), serum bilirubin from 0.99 to 0.59 mg/dL (P less than 0.05), and serum alanine aminotransferase from 132 to 61 U/L (P = 0.02), and serum cholesterol fell from 265 to 213 mg/dL (NS). The decrease in serum cholesterol was significant, P = 0.05, if data were used just from the six women whose baseline serum cholesterol levels were elevated. Serum albumin remained normal in all. The serum bilirubin levels became normal in three of four patients with elevated levels. The serum alkaline phosphatase levels became normal in four patients and the alanine aminotransferase levels in three. Liver histology improved in five patients and was stable in the remaining four based on a quantitative evaluation of coded liver biopsy specimens. The improvement in histology was primarily due to decreased portal inflammation and bile duct injury. The titer of antimitochondrial antibody decreased in seven patients. The data suggest that methotrexate may be effective treatment for precirrhotic primary biliary cirrhosis. Controlled trials are needed to evaluate long-term efficacy and toxicity.

Ten patients with well-documented primary sclerosing cholangitis who had no signs of portal hypertension or liver failure were treated with oral pulse methotrexate for at least 1 yr. The methotrexate dose averaged 15 mg/wk (0.2 mg/kg/wk). All six patients who were symptomatic became asymptomatic within 1-5 months of starting methotrexate. Biochemical tests of liver function improved in all patients. The alkaline phosphatase value decreased from a mean (+/-SD) of 373 +/- 210 IU to 140 +/- 77 IU (p = 0.0008), the mean alanine aminotransferase (ALT) from 115 +/- 74 to 76 +/- 79 U/L (p = 0.005), and the mean aspartate aminotransferase (AST) value from 88 +/- 37 to 57 +/- 40 U/L (p = 0.007). The improvement in mean bilirubin (1.19 +/- 1.41 to 0.67 +/- 0.25 mg/dl) was not statistically significant. Serum albumin remained normal (3.97 +/- 0.46 to 4.22 +/- 0.36 g/dl). Nine patients had a repeat liver biopsy after 1 yr of methotrexate therapy. Six of the nine showed histologic improvement with a reduction in inflammation. The other three liver biopsies were unchanged. Repeat cholangiograms were done in six patients. Two showed improvement. In one of the two, who had early disease, the cholangiogram became normal, and the liver biopsy was markedly improved. The other four cholangiograms showed no progression of disease. No toxicity was detected in these 10 patients. These results suggest that low-dose oral methotrexate therapy is effective in primary sclerosing cholangitis if treatment is begun before signs of portal hypertension or liver failure occur.

Liver and biliary abnormalities are well-known complications of inflammatory bowel disease (IBD). It has been suggested that using total parenteral nutrition (TPN) may further impair liver function in these patients; this seems not to be so with total enteral nutrition (TEN). However, prospective trials comparing the incidence of liver function test (LFT) abnormalities with either TPN or TEN have not been carried out. Twenty-nine IBD inpatients with normal LFT, randomized to receive either TEN with a polymeric diet or isocaloric, isonitrogenous "all-in-one" TPN because of protein-energy malnutrition and/or severe disease, were included in the study. Sixteen patients (five with ulcerative colitis and 11 with Crohn's disease) received TEN, and 13 patients (eight ulcerative colitis and five Crohn's disease) were on TPN. All patients were on systemic steroids, and nine of them were on oral metronidazole. Both groups were homogeneous regarding age, sex, diagnosis, disease activity, nutritional status, daily nutrient supply, and days on artificial nutrition. Serum albumin levels significantly increased with TEN (32 +/- 1 to 38.2 +/- 1.6 g/liter, p less than 0.01), but not with TPN (32.1 +/- 2.2 to 33.9 +/- 1.4 g/liter, NS). Clinical improvement occurred in both groups of patients as shown by the change in the disease activity indexes. In all cases, measurements of serum alkaline phosphatase, serum bilirubin, aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyltransferase were performed weekly. There were no significant differences in the initial LFT between both groups.(ABSTRACT TRUNCATED AT 250 WORDS)

We report herein the correlation of changes in serum zinc with serum proteins, serum alkaline phosphatase (AKP) activity and body weight in 15% TBSA I. burned rabbits. Serum zinc concentration reduced immediately from 181.4 to 112.4 micrograms/dl, then gradually increased and finally approached normal on 15 postburn day. Similar changes were found in serum AKP activity. AKP activity in the burned group was much lower than that in the control group. Total serum protein and albumin contents were significantly reduced and was not recovered to normal levels on 15 postburn day. Serum albumin/globulin decreased but without a turnover. Body weight dropped to a minimum on 9 postburn day and was recovered on 15 postburn day. These results reveal a correlation of serum zinc concentration with serum protein, suggesting that zinc is closely related to protein synthesis. We conclude that serum AKP activity could be used as a diagnostic criterion of postburn hypozincemia as well as an index to assess the effectiveness of supplemental zinc in burns.

Serological tests may be of value in differentiating acute and chronic bile duct obstruction because the rate of alteration of hepatic cellular integrity and function will affect the rate of cellular product release. In a canine model the common bile duct was obstructed either suddenly (N = 7) or gradually (N = 5). A control group (N = 5) had the common bile duct dissected free from the surrounding tissues. Blood was taken before and 1, 2, 4, 7, 11, 14, 17, 21, and 28 days after initiating obstruction. Serum alkaline phosphatase, bilirubin, aspartate aminotransferase, alanine aminotransferase, ornithine carbamyl transferase, and gamma-glutamyl transferase levels were significantly greater with sudden compared to gradual occlusion, and the values were larger than those in the control. The range of values of alkaline phosphatase, bilirubin, and aspartate aminotransferase did not overlap in the acute and chronic groups at specific times. Serum albumin and total protein were normal in all groups. The magnitude of alkaline phosphatase, aspartate aminotransferase, and bilirubin elevation may help in the differentiation of acute and chronic biliary obstruction.

The pre-treatment serum levels of neuron-specific enolase (NSE), phosphohexose isomerase (PHI) and circulating immune complexes (CC) as tumour markers were compared to measurements of standard haematology and biochemical indices in 73 patients with lung cancer, as an aid to differentiation of tumour type, estimating disease extent, predicting response to therapy and prognosis. Elevated NSE greater than or equal to 12.5 ng ml-1, PHI greater than or equal to 55 mgl-1 levels were observed in 55% of cases for NSE, 90% for PHI and 49% for CC. NSE was significantly elevated in 61% (25/41) of patients with SCLC (P less than 0.005) compared to 41% (13/32) with NSCLC. CC levels were significantly raised in 72% (23/32) of patients with NSCLC (P less than 0.05) compared to 32% with SCLC. The levels of NSE and PHI were not related to tumour stage but CC was significantly raised in limited compared to extensive disease in SCLC (P less than 0.05). Serum albumin was significantly lower in NSCLC compared to SCLC, and median values of alkaline phosphatase, gamma-glutamyltranspeptidase and aminoaspartate transferase were significantly higher in patients with extensive disease. The pre-treatment serum values of NSE, PHI, and CC did not predict the response to therapy or prognosis in the 73 patients with lung cancer. The most important prognostic factor was the number of abnormal routine laboratory parameters (greater than 4) in this group of patients.
