Objective: To study the effect of isoxsuprine hydrochloride on the ischaemic electrocardiographic change and trace element status in sheep.
Methods: This study was conducted from March 16 to 23, 2012, at Istanbul University, Turkey, and comprised sheep aged 6 months. The animals were divided into two equal groups. The control group was fed a standard diet and had free access to water. In the experimental group, isoxsuprine hydrochloride was injected at a dose of 0.6 mg/kg through the intramuscular route. Electrocardiographic changes, including creatine kinase and cardiac troponin-I, and serum levels of selenium, copper, calcium, magnesium, iron and zinc were investigated in healthy sheep. SPSS 15 was used for statistical analysis.
Results: The 14 sheep were divided into two groups of 7(50%) each. The overall mean weight of the study population was 35±10kg. Selenium, calcium, iron and zinc concentrations did not show any difference in serum samples (p>0.05). However, copper and magnesium concentrations decreased in serum after the administration of the drug (p<0.05). In the experimental group, ST segment depression and abnormal T-wave was found in 6(86%) animals within 60min.
Conclusions: Isoxsuprine hydrochloride increased cardiotoxicity risk in sheep.

Article Synopsis
- The study explores the use of a predicted data mining approach (PDMA) to identify biotransformable compounds that can lead to new bioactive substances.
- Isoxsuprine hydrochloride was transformed by the enzyme tyrosinase (TYR) into a novel compound, 3''-hydroxyisoxsuprine, which showed significantly improved antioxidant and anti-inflammatory properties compared to the original substance.
- The findings suggest that PDMA is a valuable method for discovering new compounds with potential applications in pharmacology and biotechnology by enhancing existing substances through biotransformation.
Spontaneous Wing Tip Edema in Captive Birds of Prey: Review of 41 Cases in the United Kingdom (2004-2022).

Article Synopsis
- - This retrospective study focused on wing tip edema (WTE) in captive raptors, revealing it as a significant condition mainly occurring in species like Harris's hawks and peregrine falcons during colder months.
- - Key findings indicated that weather conditions, like air frost and temperature, are risk factors for WTE, while early intervention and specific treatments positively influenced the chances of recovery and survival.
- - Of the cases studied, a notable percentage (74.2%) of birds returned to normal flight, highlighting the clinical importance of understanding and addressing WTE despite its rarity and the associated morbidity and mortality risks.

This study assesses the potential positive impact of a 0.05% isoxsuprine ointment on psoriasiform skin inflammation generated by imiquimod in mouse models. Thirty-two male albino mice were allocated into four groups: the control group (which received topical emollients twice daily for 16 days), the induction group (which received imiquimod cream (5%) for 8 days, twice daily followed by petrolatum gel (15%) for another 8 days), and the other two groups, which received imiquimod cream (5%) for 8 days followed by either clobetasol ointment (0.

To improve the fertility of cervical artificial insemination (AI) in sheep, we investigated isoxsuprine HCl usage on the cervical passage during cervical AI. We also compared cervical and laparoscopic AI fertility results of using chilled semen at different durations. Semen was collected from rams and diluted as 20 × 10 or 400 × 10 spermatozoa/straw for laparoscopic and cervical AI, respectively, and chilled to 4°C within 2 h.

Ischemic stroke is the second-leading cause of death. Hyperglycemia, which is characteristic of diabetes mellitus, contributes to the development of endothelial dysfunction and increases the risk of stroke. Isoxsuprine is an efficient beta-adrenergic agonist that improves blood flow to the ischemic aria and stops the infarct core from growing.
