Piroplasmosis is a zoonotic protozoan disease transmitted by ticks. The full geographical range of canine piroplasms has been found in dogs in the Middle East, parts of Africa, North America, and Europe. Following our studies on molecular detection of piroplasmosis in the south of Iran, we found Theileria annulata in two herd dogs, as well as information on their 18S rRNA gene sequences. Piroplasmosis agents were detected by PCR of 280 blood samples collected from dogs in seven regions of the Shiraz suburbia in southern Iran, between November 2009 and June 2011. Two positive samples from Shiraz were infected with T. annulata, and one sample was infected with Babesia canis. PCR positive samples were further analyzed by sequence analysis. The results of this study reconfirmed that T. annulata are not always as host specific as accepted. This is the first report of T. annulata in herd dogs in southern Iran and the second report of T. annulata in dogs worldwide.

Background: Doxorubicin is a favorite drug for feasting many malignancies. All organs' hepatic toxic effects are destructive and lead to use with caution. Then, it is necessary to increase antioxidants accompanied with doxorubicin to reduce its toxicity. Vitamin E is an antioxidant with harmful consequences. Omega-3 is an antioxidant similarly. The healing capacity of Vitamin E- Omega-3 was investigated together against doxorubicin. Methods: Thirty balb/c mice have divided a weight of 25 g into five equal groups of six mice each. The groups were classified as Control: normal saline; DOX: Doxorubicin; Vitamin E: Vitamin E + DOX; Omega-3; Omega-3 + DOX; Both Vitamin E- Omega-3 + DOX. The histopathology was set to describe vacuolar degeneration, inflammation, and necrosis. Immunohistochemistry was performed to estimate the expression of tumor necrosis factor (TNFα), demonstrating the inflammation. Results: DOX-induced hepatic injury and increased TNF-α expression were seen more than alone when co-administered with vitamin E and omega-3. A significant decrease was shown in the ALT, AST, GGT, and ALP levels compared to the control. The Glutathione peroxidase and Catalase enzyme activities were higher in the co-administered Vitamin E- Omega-3 group than that received Vit E or Omega-3. Conclusions: Co-administration of Vitamin E and Omega-3 have a more repair capacity with controlling effects on Doxorubicin-induced liver toxicity.

Background: Doxorubicin is preferred to cure many malignancies. Its nephrotoxicity is a dangerous nature that is to operate with a warning. Antioxidants accompanied by anticancer could moderate the various side effects. Objectives: Cichorium intybus (C. intybus) has nephron-protective effects. Melatonin stands as an antioxidant equivalent to others. The repairing effects of C. intybus-melatonin against the toxicity effects of doxorubicin on the kidneys were studied. Methods: Thirty 20 g to 25 g, balb/c mice were divided into 5 identical groups (n: 6). The research was grouped as control saline; DOX with the injection of doxorubicin; Chicory with the administration of the C. intybus complete extract following DOX; melatonin with the administration of the melatonin following DOX; both: with the administration of the chicory and melatonin following DOX. The histopathological study was set to determine degeneration, inflammation, and necrosis. Results: The mean of each histological phenomenon in the control group was significantly lower than in the DOX group. In the histopathology, we saw that all the treating groups, including C. intybus extract-received, melatonin-received, both of them received improved better than the doxorubicin-received group. The best improving mean was seen in the latter group. The DOX-induced nephrotoxicity could be improved by using the C. intybus extract and melatonin synchronously as therapeutic care. Conclusions: Synchronous administration of the chicory and melatonin has a healing potency against doxorubicin-induced nephrotoxicity.

Background: Doxorubicin is anticancer that is a choice for the treatment of many malignancies. The nature of its toxic effects on the liver and other organs is the harmful character that leads to use with caution. Then, it is necessary to supplement an antioxidant with doxorubicin to reduce its side effects. Objectives: Cichorium intybus (C. intybus) is a plant with hepatoprotective effects. Melatonin is an antioxidant similar to vitamins. We investigated the repairing effects of C. intybus -melatonin together against doxorubicin-induced hepatotoxicity. Methods: Thirty balb/c mice in the weight range of 20 g to 25 g were divided into 5 equal groups of 6 animals each. The groups were as Control: normal saline; DOX: doxorubicin; Chicory: chicory whole plant extract + DOX; Melatonin; melatonin + DOX; Both Chicory-Melatonin + DOX. We assessed histopathology to define necrosis, vacuolar degeneration, and inflammation. In addition, we used immunohistochemistry to evaluate the TNFα proving the rate of inflammation. Results: The mean sum of histological grading in the control group was 0.00 in contrast to severe damage of the hepatic parenchyma grading 11.34 in sum. The mean sum grade of the other groups including Chicory, Melatonin, and Both Chicory-Melatonin were 8.17, 4.18, and 2.49, respectively. We found that the increased liver damage and TNF-α expression induced by DOX could be improved by applying therapeutic care with the coadministration of the C. intybus extract and Melatonin. Conclusions: Chicory and Melatonin have a healing ability against doxorubicin-induced hepatic lesions.
