An experiment was designed to investigate the practical possibility of incorporating small quantities of molybdenum salts into the high copper diets of intensively fattening lambs to prevent or reduce the gradual accumulation of copper from feed. At slaughter (14 weeks of age) lambs which had received Mo supplement (7.7 ppm Mo) showed liver copper levels which were 40.1 per cent lower than those in the control group which, in turn, presented a mean liver copper concentration near the upper limit of the normal range for adult sheep. Changes in blood ceruloplasmin and SGOT levels and in the comparative rate of accumulation of liver copper indicated that the addition of ammonium molybdate to the concentrate diet might be a useful method of reducing the risk of nutritional copper poisoning in housed sheep.

An acute phase reaction was elicited in four horses to which Freund's adjuvant was administered intramuscularly. The localised inflammation was accompanied by changes in the plasma concentrations of copper, iron and zinc. The plasma copper concentration, the plasma ceruloplasmin copper concentration and the ceruloplasmin oxidase activity in the plasma steadily increased to a maximum 24 days after the administration of the adjuvant. At this time, the plasma copper concentration was 2.2 micrograms/ml, a 90 per cent increase over the baseline concentration. The ratio of the concentration of plasma ceruloplasmin copper to plasma copper remained constant, indicating that the non-ceruloplasmin bound copper component of the plasma is also an acute phase reactant in the horse. The plasma zinc and iron concentrations decreased to 59 per cent and 30 per cent of their respective baseline concentrations and the severity of the inflammation appeared to influence the plasma concentrations of each metal. Weak correlations between the plasma fibrinogen concentration and the plasma copper and zinc concentrations of 25 horses with plasma fibrinogen concentrations of 5 g/litre or greater indicated that a single measurement of plasma copper concentration is not useful in the diagnosis of non-specific inflammatory disorders of the horse. However, the results suggest that the plasma copper concentrations in serial samples may be used to monitor the resolution of inflammatory disorders in the horse.

An attempt has been made to assess the importance of systemic sites of interaction from the effect of dietary molybdenum (Mo) on the protection afforded by a single sc injection of copper (Cu) to 29 initially hypocupraemic 5-year-old ewes, maintained on a low Cu diet. They were fed a diet of 1 kg/day containing 1.3 mg of Cu/kg supplemented with sodium sulphate which provided 1.7 gm of sodium per kg. Group A was given no further supplement. Group B was given added Mo, 25 mg/kg. Group C was given added Cu, 10 mg/kg. After 7 months, several animals in each group were injected sc with a single dose of 46.5 mg of Cu in the form of copper calcium edetate (Coprin). Blood samples were taken at intervals from the injected ewes over a 250-day period. All ewes were mated after 12 months on the diet. Injected ewes were approaching the 4th month of gestation when the last blood sample was taken at 250 days. Total Cu in plasma was determined by atomic absorption spectometry. Direct reacting Cu in plasma, cerulosplasmin oxidase activity, and hemoglobin were also estimated. Plasma Cu concentrations had increased to normal levels in 14 days in Group A after the Cu injections. Group B animals showed a greater increase, mean values exceeding those of Groups A and C, between Days 28-129 (p less than .01). Plasma Cu levels declined in ewes not given supplementary Cu after the 177th day. The final values for Groups A and B were similar to those found before injection. The direct reacting Cu in each group was increased after 7 days (p less than .05). This effect was most marked in the Mo supplemented ewes (Group B). The effect of Mo persisted until the final bleeding. Direct reacting Cu was only a minor part of the early response in total plasma copper of Group B ewes. Dietary Mo did not inhibit the incorporation of injected Cu into ceruloplasmin. The Mo-supplemented ewes were in poorer condition than copper-supplemented ewes. All groups gained in weight after the injections. The sc injection of Cu at 5 months prior to mating imporved fertility in Groups A and B. There was no evidence that dietary Mo impa ired the metabolism of parenteral Cu. However, it is known to deplete r uminants of Cu when the diet provides the only source of Cu. It is ther efore thought that the site of the Cu with Mo interaction is in the gut. If infertility due to Cu deficiency is suspected in a flock, an injection of Cu immediately prior to mating may improve conception rate and provide sufficient Cu to reduce the incidence of swayback.

The rate of uterine involution postpartum was monitored in 13 suckling mule ewes by using radio-opaque markers and radiography, and each ewe was also monitored for intrauterine bacterial contamination during the first week, using a sterile guarded swab. Peripheral plasma or serum concentrations of haptoglobin, seromucoid, ceruloplasmin and 15-keto-13,14-dihydro-prostaglandin F2 alpha (PGFM) were measured up to six weeks postpartum. The maximum reduction in the length of the uterine body and in the diameters of the horns occurred by 28 days postpartum, except in one ewe in which the size of the uterus continued to decrease for 42 days. Four ewes were positive for intrauterine bacterial contamination; Escherichia coli, clostridial species, Staphylococcus aureus, Streptococcus uberis and Enterococcus species were isolated in pure or mixed culture. The presence of intrauterine bacteria did not affect the time for the completion of uterine involution. No bacteria were isolated from the ewe in which involution was delayed, but it had a different acute phase protein response and was therefore excluded from further analyses. In the remaining 12 ewes the mean postpartum haptoglobin response increased, with peak concentrations occurring on day 1, and decreased slowly as uterine involution progressed, but the four contaminated ewes had a significantly greater response. There was no difference between the prepartum and postpartum concentrations of seromucoid in the eight sterile ewes, but significant increases were observed in the contaminated group; the concentrations of ceruloplasmin did not vary in either group. The concentrations of PGFM were higher during the early postpartum period in the ewes with contaminated uteri.

Repeated ultrasonographic examinations and collections of blood samples and uterine lumenal swabs between seven and 28 days after calving were used to examine the relative effects of bacterial contamination and involution of the uterus on the concentrations of acute phase proteins in the blood of 26 dairy cows. The severity of bacterial contamination, as determined by the total bacterial growth score, was a significant variable for the concentrations of the acute phase proteins alpha1-acid glycoprotein (P < 0.0001), haptoglobin (P < 0.05) and ceruloplasmin (P < 0.0001). In addition, the concentrations of alpha1-acid glycoprotein and ceruloplasmin were increased in the cows from which Escherichia coli (P < 0.0001) and Arcanobacterium pyogenes (P < 0.05), respectively, were isolated from the uterine lumen. Uterine involution, as determined by the decreasing diameter of the previously gravid uterine horn, was associated with a decrease in the concentrations of alpha1-acid glycoprotein (P < 0.005), haptoglobin (P < 0.05) and ceruloplasmin (P < 0.01). However, the response of the acute phase proteins to bacterial contamination was independent of the day on which the samples were collected, indicating that their concentrations were increased by bacterial contamination in addition to the changes associated with uterine involution.

The concentrations of haptoglobin, C-reactive protein and ceruloplasmin were measured in symptomatic and asymptomatic dogs naturally infected by Leishmania infantum, and in healthy uninfected dogs to determine the potential value of these proteins for the diagnosis and prognosis of leishmaniasis. The concentrations of the acute phase proteins were significantly higher in the dogs with leishmaniasis than in the control dogs, and the concentration of C-reactive protein was significantly higher in the symptomatic dogs than in the asymptomatic dogs. There were no correlations between the acute phase proteins and the gamma globulins, the albumin/globulin ratio or the titre of anti-leishmanial antibodies.

Cisplatin is a widely used anticancer drug, but at high dose, it can produce undesirable side effects such as hepatotoxicity. Because Curcuma xanthorrhiza Roxb. (Zingiberaceae) has been traditionally used to treat liver disorders, the protective effect of xanthorrhizol, which is isolated from C. xanthorrhiza, on cisplatin-induced hepatotoxicity was evaluated in mice. The pretreatment of xanthorrhizol (200 mg/kg/day, po) for 4 days prevented the hepatotoxicity induced by cisplatin (45 mg/kg, ip) with statistical significance. Interestingly, it abrogated cisplatin-induced DNA-binding activity of nuclear factor-kappaB (NF-kappaB), which consequently affected mRNA expression levels of NF-kappaB-dependent genes, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2), even in part. It also attenuated the cisplatin-suppressed DNA-binding activity of activator protein 1 (AP-1). Using differential display reverse transcription-polymerase chain reaction (DDRT-PCR), seven upregulated genes including S100 calcium binding protein A9 (S100A9) mRNA and antigenic determinant for rec-A protein mRNA and five downregulated genes including caseinolytic protease X (ClpX) mRNA and ceruloplasmin (CP) mRNA by cisplatin were identified. Although these mRNA expression patterns were not totally consistent with gel shift patterns, altered expression levels by cisplatin were reversed by the pretreatment of xanthorrhizol. In conclusion, the ability of xanthorrhizol to regulate the DNA-binding activities of transcription factors, NF-kappaB and AP-1, could be one possible mechanism to elucidate the preventive effect of xanthorrhizol on cisplatin-induced hepatotoxicity. Furthermore, genes identified in this study could be helpful to understand the mechanism of cisplatin-induced hepatotoxicity. Finally, the combination treatment of xanthorrhizol and cisplatin may provide more advantage than single treatment of cisplatin in cancer therapy.
