Results-Of 4,387 dogs with samples analyzed retrospectively, 1,426 (32.5%) had regenerative anemia. Of these, 168 (11.8%) had macrocytic hypochromic anemia. High mean cell volume and low mean cell hemoglobin concentration had low sensitivity (11%), high specificity (98%), and moderate accuracy (70%) when used to identify regenerative anemia. Use of polychromasia alone had an accuracy of 77%, and use of polychromasia combined with a high RBC distribution width (RDW) had an accuracy of 79%. Results obtained with the in-house analyzer were similar.
Conclusions and Clinical Relevance-Results suggested that most regenerative anemias in dogs were
not macrocytic hypochromic. Polychromasia, see more with or without high RDW, was a more accurate indicator than other erythrocyte indices of regenerative selleck compound anemia. To avoid a false diagnosis of nonregenerative anemia, a blood smear should be evaluated in anemic dogs when a reticulocyte count is not available. (J

“Isotretinoin is a retinoid widely used for the treatment of severe nodulocystic acne. Although it has broad side effects, there is no well-designed study about its effects on the ovary. This study investigated possible toxic effects of isotretinoin on female gonads. A total of 30 female rats were randomly divided into three equal groups according to the dose of isotretinoin they were administered: 0 mg/kg/day (group 1), 7.5 mg/kg/day (group 2) or 15 mg/kg/day
(group 3). Thirty days after the treatment, the effects of isotretinoin on the ovaries were evaluated with serum anti-Mullerian hormone (AMH) concentrations, apoptosis by TUNEL assay and immunohistochemical observations by proliferating BVD-523 research buy cell nuclear antigen (PCNA). The percentage of atretic follicles was calculated for each stage of folliculogenesis. The serum AMH concentrations were found to be lower in both isotretinoin groups. The percentage of atretic follicles in both isotretinoin groups was higher than the control. The number of PCNA-positive granulosa cells was decreased in the isotretinoin groups. The number of ovarian follicles with apoptotic granulosa cells was increased in the experimental groups. These data are the first to identify that exposure of isotretinoin may be responsible for decreased ovarian reserve and toxic effects on rat ovaries. RBMOnline Crown Copyright (C) 2013.
