Among various plant species growing in different regions of Iran, a large number of plants contain chemical compounds which are toxic to animals and humans. Among those poisonous plants, cardiotoxic plants are important due to the acute nature of their toxicity and frequent lethal livestock and human intoxications. Cardiotoxic plants of Apocynaceae family, Nerium oleander, N. indicum and Thevetia peruviana contain cardiac glycosides including oleandrin, oleandroside and thevetin A-C. Plants of Taxaceae family, Taxus baccata and T. brevifolia contain taxine alkaloids, including taxine A and B. The toxic effects of cardiac glycosides are primarily attributed to inhibition of plasmalemmal Na+/ K+-ATPase which results into the accumulation of intracellular Ca2+ and, depending to its severity, inotropic or arrhythmic effects are seen. Taxine B, the prominent alkaloid in Taxus spp. block sodium and calcium channels preferentially in cardiac myocytes, thus causing conduction abnormalities. Various cardiac arrhythmias in acute cases of poisoning with aforementioned plants result in acute heart failure and death. Post mortem findings are non-diagnostic and toxicological analysis of gastrointestinal tract content or body fluids is used for detection of cardiac glycosides and taxines.}, keywords = {Oleander poisoning,yew poisoning,cardiac glycosides,taxines,cardiac arrhythmia}, url = {https://ijvst.um.ac.ir/article_29954.html}, eprint = {https://ijvst.um.ac.ir/article_29954_49ccc788121ccb328a1539b2c07d56b5.pdf} } @article { author = {Rassouli, Ali and Khanamani Falahatipour, Sakineh and Hosseinzadeh Ardakani, Yalda and Akbari Javar, Hamid and Kiani, Katayoun and Zahraee Salehi, Taghi}, title = {Preparation and in vitro evaluation of chitosan-based films for the sustained delivery of enrofloxacin}, journal = {Iranian Journal of Veterinary Science and Technology}, volume = {10}, number = {1}, pages = {13-20}, year = {2018}, publisher = {Ferdowsi University of Mashhad}, issn = {2008-465X}, eissn = {2423-6306}, doi = {10.22067/veterinary.v10i1.70288}, abstract = {The implantable drug products are developed mainly to sustain the drug release. This study was conducted to formulate and evaluate cross-linked films of chitosan/β-glycerophosphate (β-GP) for the sustained delivery of enrofloxacin (ENR). Two types of formulations, single-layer (F1 and F2) and triple-layer (F3 and F4) films, were prepared. In vitro drug release, kinetic modelling, Fourier transform infrared spectroscopy (FTIR) spectra, morphological and microbiological studies were performed. Drug release from F1 and F2 continued up to 5 hours but from F3 and F4, it was extended over 96 and 168 hours, respectively. The cumulative drug release for F1, F2, F3 and F4 were 72.6, 70.1, 90.5 and 82.4%, respectively. The inhibition zones of bacterial growth by using positive controls and single layer films were significantly greater than those of triple-layer films (p < 0.05), indicating sustained drug release pattern of the multi-layer films.

The serum concentrations of fructosamine, glucose, albumin, and total protein were measured. The maximum concentration of fructosamine was at 12 hours post-partum and decreased thereafter. Serum concentration of glucose significantly increased from D-15 up to 12 hours post-partum and then decreased and stayed at the same level. The serum concentrations of albumin and total protein significantly increased during post-partum period. There were significant correlations between fructosamine and glucose concentrations at post-partum period and overall time of the study. Linear regression analysis between each sampling amount of glucose and three consecutive fructosamine concentrations revealed significant positive correlation between glucose of each sampling time with the fructosamine of first sampling time thereafter. According to the correlation between glucose and fructosamine amounts during the study, especially post-partum period in Saanen goat, fructosamine measurement could be used as a useful indicator of energy economy and probably stress in Sannen goat; but controversy between reports in ruminants needs further studies for better understanding of fructosamine as energy biomarker in ruminants.}, keywords = {albumin,Fructosamine,Glucose,Saanen goat,Total Protein}, url = {https://ijvst.um.ac.ir/article_30083.html}, eprint = {https://ijvst.um.ac.ir/article_30083_4d5881d55699614cdecc2463a5eb3833.pdf} } @article { author = {Abdolvahabi, Safoora and Zaeemi, Mahdieh and Mohri, Mehrdad and Naserian, Abbas Ali}, title = {The hematological profile changes in Saanen goat kids from birth to 3 months of age}, journal = {Iranian Journal of Veterinary Science and Technology}, volume = {10}, number = {1}, pages = {33-38}, year = {2018}, publisher = {Ferdowsi University of Mashhad}, issn = {2008-465X}, eissn = {2423-6306}, doi = {10.22067/veterinary.v10i1.66272}, abstract = {This study performed to determine hematological parameters in Saanen goats’ kids from birth until 3 months of age.

Hence, this study was carried out to investigate the occurrence of neonatal isoerythrolysis in Arabian horses of Khouzestan and assess the hematologic and serum biochemical profile of affected foals. A total of 20 neonatal foals, under one week of age, and their dams were involved in this study. Clinical examinations revealed no abnormality except in one foal with icteric mucous membranes, lethargy, tachycardia, tachypnea, hypothermia and hemoglobinuria which led to death. The diagnosis of neonatal isoerythrolysis was made based on erythrocyte agglutination in cross-match test between the mare serum and foal erythrocytes with the titer of 1:128, while other studied cases were assumed negative according to the test results. In the laboratory assessment, the foal with hemolytic anemia showed a major decline in hematocrit, hemoglobin concentration and erythrocyte count along with considerable leukocytosis and neutrophilia. Serum total and direct bilirubin concentrations in the NI case was about ten times higher than in the rest of the foals. This study revealed that neonatal isoerythrolysis can occur in Arabian foals of Khouzestan and is associated with severe anemia and icterus which may lead to death.
