Evaluation of the effect of Carvacrol on retinal neovascularization in rats
2021
Kaymaz, Abdulgani | Eri̇msah, Sevilay
To compare the effect of intraperitoneal administered Carvacrol with bevacizumab in an oxygen-induced retinopathy (OIR) model in rats. Twenty-eight newborn rats were included in the study and the OIR model was created with the 50/10% oxygen style. The study consisted of 4 groups and each rat in the groups received an intraperitoneal injection of 0.01 mL once on the postnatal 14th day. While the OIR model was not created in Group I (control group), it was created for Groups II, III, and IV. Groups I and II were injected with 0.9% NaCl solution, Group III with bevacizumab, and Group IV with carvacrol. The rats were sacrificed on the postnatal 18th day.Histopathological and immunohistochemical studies showed that the number of retinal vascular endothelial cells (RVECs) and nuclear factor (NF)-κB levels decreased similarly in Group III and Group IV compared to Group II. RVECs values for Group I, Group II, Group III and Group IV were measured as 1.26±0.80, 27.10±3.63, 7.54±1.38, and 6.22±1.22, respectively and it differed significantly between groups (p<0.001). Likewise, NF-κB levels were recorded as 0.61 ± 0.30, 4.36±0.65, 2.68±0.44, and 2.85±0.58, respectively and it differed significantly between groups (p<0.001). On the other hand, RVECs and NF-κB levels were similar between Group III, and Group IV (p values were 0.58 and 0.91, respectively).The study demonstrated that carvacrol significantly reduced retinal pathological neovascularizations, RVECs, and NF-κB levels. Moreover, the observed effects were comparable to those of bevacizumab.

The study was focused to investigate the occurrence of a fatal capture myopathy (CM) after chemical immobilization during translocation in different places and to evaluate serum enzymes of stressed deer and pathologic alteration of vital organs of dead animals due to CM. Materials and Methods: The experimental data was collected from Bangladesh National Zoo, Dhaka and the experiment was conducted at the Department of Surgery and Obstetrics, Bangladesh Agricultural University, Mymensingh. Immediate after capture the animals were allowed to normalize body temperature by pouring sufficient water over the body. Peripheral blood was aspirated from jugular vein for serum biochemical analysis. Once the animals died, vital organs were collected and processed for histology.Data from 2013 to 2018 revealed 178 animals captured through darting and among them 40 animals died due to post-capture myopathy reflecting death rate of 22.47%. We have closely studied on 16 animals captured on different occasions. Serum enzyme analysis were exhibited increased levels of ALT, AST, Bilirubin, Creatinine, BUN, LDH, CK, Troponin, Cholesterol, Triglyceride, HDL and LDL and were highly indicative of stress-linked muscle and organ damage. The macroscopic lesions consisted of muscular and cardiac degeneration, edema, hemorrhage and congestion in lung, adrenal gland and in kidney. Microscopically there were loss of striation and fragmentation of skeletal muscle, formation of contraction band necrosis in myocardial fiber, degenerative changes in renal tubule and formation of central intraluminal eosinophilic casts.The pathological findings were indicative of capture myopathy in spotted deer. This report underlines that mortality from capture is a risk that must be considered during restocking programs.
اظهر المزيد [+] اقل [-]Effect of Pendulous Crop on Certain Clinicopathological and Biochemical Parameters in Japanese Quails
2020
Celik, Ozgur Yasar | Irak, Kıvanc
In this case report, clinicopathological findings and certain biochemical parameters were presented in quails with the pendulous crop. The animal material of the study consists of a total of 3 Japanese quails (Coturnix coturnix japonica). The quails were examined clinically first, followed by the post-mortem examinations. The investigations of Na, K, Mg, total TP and Alb were conducted using autoanalyzer. The plasma levels of sodium, potassium, magnesium, total protein and albumin in the blood samples collected from the animals were found to be higher than the averages for quails. Postmortem examination of quails has revealed that the veins of their crops were prominently pronounced and that the crops were filled with a yellowish, foulodor liquid containing whole grain particles. Furthermore, the crop mucosa of an animal contained ulcerative lesions. As a result, it was found that certain mineral levels and protein profiles of animals were affected by the pendulous crop phenomenon, and that laboratory findings should be considered alongside physical findings when dealing with it.
