The effect of intraperitoneally administered penicillic acid, a mycotoxin produced by several species of Penicillium and Aspergillus, on female dogs of mixed breeding was determined by serum tests, by observation of clinical signs and survival times, and by evaluation of gross and microscopic lesions. Combination studies employing penicillic acid and a second mycotoxin, rubratoxin B, also were undertaken. Post mortem examination disclosed hemorrhaging of the serosal surfaces of the abdomen of dogs receiving penicillic acid. The most significant histologic change observed in penicillic-acid-treated dogs was congestion and dilatation of hepatic sinusoids. Extensive hepatic changes of the liver were noted only in the dog receiving 20 mg/kg penicillic acid. There was no evidence of parenchymal necrosis in any of the liver samples examined from animals given penicillic acid. A predominently peripheral lobular depletion of glycogen in parenchymal cytoplasm also was seen in liver sections from animals exposed to penicillic acid. Although slight decreases in lactic dehydrogenase were observed, no trends were detected in the several blood enzymes and serum constituents examined that could be specifically related to penicillic acid intoxification. Glutamic-oxaloacetic transaminase, lactic dehydrogenase and alkaline phosphatase activities and survival time varied in relation to duration of exposure and total dose of rubratoxin B administered. The lesions in animals injected with 1.0 mg/kg rubratoxin B consisted of mild hepatic necrosis and degenerative changes in renal tubular epithelium. An additive effect due to the combined administration of penicillic acid and rubratoxin B was observed only by an elevation in serum sodium and chlorine levels.

The effect of ip administrated aflatoxin B1 and rubratoxin B, singly and in combination, on dogs was determined by serum tests, by observations of clinical signs and survival times, and by evaluation of gross and microscopic lesions. The dog is sensitive to the toxic effects of both mycotoxins. Glutamic-oxaloacetic transaminase, lactic dehydrogenase and alkaline phosphatase activities and survival time varied in relation to dose and to the mycotoxin(s) administered. All three plasma enzymes were elevated regardless of dose with the combination of aflatoxin B1/rubratoxin B at 24 hr after dosing, except LDH, which was within the normal range but only at the lowest dose level. Several serum constituents including BUN, cholesterol, uric acid, and total bilirubin were elevated, whereas serum glucose was depressed in dogs treated with the multiple-toxin regimen; these changes were not seen in dogs given only aflatoxin B1 but were characteristic in rubratoxin-treated animals. In general, gross findings at necropsy were similar in all dogs regardless of the dose regimen. A striking similarity existed in the histologic changes observed between lesions experimentally induced by the mycotoxin combination and those lesions reported for dogs fed toxic feed in laboratory studies or in natural cases of hepatitis X. Of particular similarity were the severe kidney lesions observed in dogs exposed to the mycotoxin combination and kidney lesions reported in natural outbreaks of hepatitis X. There can be little doubt of an association between hepatitis X and aflatoxin B1, although it is apparent that the disease probably involves more than a single toxic factor. Our results suggest that hepatitis X in dogs includes aflatoxin B1 as a primary etiological factor but that rubratoxin B also may be involved.

Blood serum of pygmy goats (both sexes, and castrated males) was analyzed to establish biochemical reference values. Influence of age on reference values was also studied. Serum biochemical analyses were made for urea nitrogen, creatinin, bilirubin, lactate dehydrogenase, aspartate aminotransferase, alkaline phosphatase, glucose, uric acid, and total lipids. These serum values for pygmy goats were similar to those reported for man, except as follows: Aspartate aminotransferase activities were slightly higher than those reported for man. Glucose concentrations in pygmy goats were slightly lower than in human beings, and uric acid levels were significantly lower than the values for man. Female and castrated male goats had lower total lipid concentrations than did human beings, whereas intact males had higher concentrations. Thus, of the 9 measured variables for pygmy goats, 5 were comparable to human values. This, together with other attributes, including the small size which conduces to economics of maintenance and enhances the desirability of using pygmy goats in research.

A double-blind study was carried out in 152 Canadian patients, 76 given Duogastrone (carbenoxolone sodium) capsules, 50 mg qid, and 76 given placebo capsules qid for 6 weeks. All patients had a duodenal ulcer diagnosed by roentgenography or endoscopy, or both. Evaluation of the efficacy of Duogastrone therapy was based on data from the 119 patients (59 treated with Duogastrone and 60 with placebo) who met all the strict requirements of the protocol. The ulcers healed completely in 75% (44/59) of the patients treated with Duogastrone and in 48% (29/60) of those treated with placebo; this difference is significant (P less than 0.01). The proportions were similar in the patients assessed only endoscopically: 76% (32/42) and 55% (26/47), respectively. In the group treated with Duogastrone the following side effects were noted: weight gain, edema, mild hypokalemia, increase in blood pressure and slight increases in serum concentrations of lactic dehydrogenase and alkaline phosphatase. None was serious. However, close clinical monitoring by weekly visits to their physician is recommended for every patient undergoing Duogastrone therapy, at least during the 1st month.

The activities of eight enzymes (glutamate dehydrogenase, sorbital dehydrogenase, malate dehydrogenase, lactate dehydrogenase, alpha-hydroxy butyrate dehydrogenase, gamma-glutamyl transpeptidase, alkaline phosphatase and creatine kinase) were determined in tissue homogenates of liver, kidney, spleen, lung, small intestine, cardiac muscle and skeletal muscle, from 15 Large White pigs of three different ages (1.5 weeks, 18--22 weeks and 113 weeks). The results showed that variation in tissue enzyme concentration due to differences in sex is minimal. Variation due to differences in age, however, appears to be of greater importance, particularly when considering young animals. These age differences may affect the interpretation of plasma enzyme changes due to tissue damage, and the use of additional enzyme assays as an aid to interpretation in these cases is advisable.

Investigations were performed to evaluate the activities of serum glutamic oxalacetic and glutamic pyruvic transaminases, alkaline phosphatase and lactate-dehydrogenase enzymes in rats intoxicated by different doses of carbon disulfide. Serum GOT and GPT activities were elevated which may be due to CS2 effect on cell membrane permeability. Serum-alkaline-phosphatase activity showed also increment, which was again attributed to the liver affection. A significant rise in serum-lactate-dehydrogenase activity which was referred to be as a result of muscle-lactate dehydrogenase release into the blood circulation.

Bone marrow acid phosphatase has been reported to be a sensitive indicator of early bony metastasis from adenocarcinoma of the prostate. In order to evaluate this hypothesis, we measured bone marrow acid and alkaline phosphatase, lactic dehydrogenase, and calcium levels in a group of 84 patients with a variety of problems, including 18 with cancer of the prostate. We found that the bone marrow acid and alkaline phosphatase and lactic dehydrogenase were elevated and calcium was depressed in most patients. Among patients with prostate cancer, bone marrow acid phosphatase was not significantly different between those with or without bone metastases. In addition, the patients with prostatic cancer did not have higher levels of bone marrow acid phosphatase than subjects with other malignant and nonmalignant conditions. The level of acid and alkaline phosphatase, lactic dehydrogenase and calcium varied predictably with the aspiration technique used and was independent of sex, disease state or method of chemical determination. Due to this variation, we believe that bone marrow enzyme and calcium levels are of no value in the detection of metastases in patients with prostate cancer.

Human ovarian follicles showed activity of alkaline phosphatase, acid phosphatase (AcP) leucine aminopeptidase, and lactate dehydrogenase (LDH) in the theca interna. The granulosa of nonovulatory tertiary follicles showed moderate activity, whereas that of preovulatory Graafian follicles showed strong activity of LDH and AcP. The activity of these enzymes in the follicular fluid was measured. In nonovulatory tertiary follicles, activity of 3beta-ol-steroid dehydrogenase (3beta-OHSD) was found only in the theca interna; their fluid contained 290 ng/ml of progesterone and 502 ng/ml of 17beta-estradiol (average). Preovulatory Graafian follicles showed activity of 3beta-OHSD in the theca as well as in the granulosa. The progesterone concentration of the fluid was 7037 ng/ml and the 17beta-estradiol concentration was 2800 ng/ml (average). More oocytes could be aspirated from ovaries of younger women than from those of older women. In both age groups one out of three oocytes was degenerated. Oocytes with preovulatory changes were found only in follicles with preovulatory changes in their walls. Degenerated oocytes were found in some nonovulatory follicles as well as in some follicles with preovulatory changes in their walls.

Methyl 4-hydroxy-3-nitrobenzimidate hydrochloride (I) is presented as a newly developed amidination reagent. It is synthesized in two steps from commercially available 4-hydroxybenzonitrile. Its incorporation into proteins can be easily determined spectroscopically. The activities of the three enzymes lactate dehydrogenase (pig heart), alkaline phosphatase (calf intestine) and tryptophan synthase (E. coli) were not greatly reduced after modification with the reagent. The nitro groups can be reduced by mild treatment with Na2S2O4 without alteration of the enzymatic activity. The newly formed aromatic amino groups can further be made to react at lower pH than the native amino groups.

The effects of several drugs were tested on analytical methods used in the clinical laboratory to measure the concentration of certain chemical constituents and activity of enzymes in body fluids. Drugs were studied initially at reported toxic concentrations, but if they had an effect at this level effects of lower concentrations were also investigated. The drugs were first studied on the methods of the Technicon SMACTM analyzer. Subsequently, methods in use with the Du Pont ACA and Technicon AutoAnalyzerTM I or II were evaluated. The most commonly affected method was the phosphotungstate reduction procedure for measuring uric acid. However, methods for measuring total protein and albumin were also affected frequently, as were determinations of alkaline phosphatase and lactate dehydrogenase activity.
