The present study aimed to record the arthropod fauna of medico-legal importance in an urban city: El Delengat, Beheira governorate, Egypt, by studying the succession of insects and the duration of the decomposition of rabbit carrions injected with Aluminum phosphide (AlP). In our study the total of twelve male rabbits, Oryctolagus cuniculus L, each weighing 1,25 kg were used. The experiment was conducted in summer. Three replicate experiments were conducted, for each experiment, 3 rabbits were administered intragastrically dosages of 27.4 mg, 13.7 mg, 54.8 mg of aluminum phosphide by body weight representing LD50, ½ LD50, 2 LD50, respectively. The fourth rabbit was used as a control, injected by saline solution. The recorded entomofauna was denoted in 5 orders, 12 families, and 17 genera and species. Necrophagous arthropods that colonized rabbit carrions were substantially of Diptera and Coleoptera orders. Calliphorid insects was the foremost family that colonizing the different carrions. AlP appeared to delay the decomposition process in ½ LD50 and 2 LD50 carrions. These results are the primary record of the arthropod successive pattern on aluminum phosphide remains, it will provide useful data in any future case studies involving AlP intoxication.

Several authors have been studying the microvascularization pattern of the ovary in different animals. To determine the microvascularization pattern using the corrosive-resin casting method, casts of the vascular network were prepared and examined by scanning electron microscopy. However, the same procedure has rarely been used to study the microvascularization pattern of the uterine tube itself. The microvascularization of the uterine tube has always been associated microvascularization studies of the ovary. This study analyses the microvascularization of the uterine tube, pointing out differences between the region of the tube itself and it's infundibulum. In this study we used uterine tubes from adult female rabbits. Anesthesia was carried out with Ketalar (5mg/kg body weight); after that saline solution and 2,5% glutaraldehyde were injected through the left ventricle. This procedure was followed by mercox 2B injection. After polymerization the samples were collected and immersed in warm water (60°C). Then samples underwent tissue digestion.

The general objective of this study was to evaluate the effect of Naja nigricollis venom on some vital organs of rabbits. To carry out this study, nine (9) rabbits including five (5) males and four (4) females were divided into two (2) control lots and one (1) experimental lot. Each control lot was composed of three (3) rabbits (males or females) while the experimental lot was comprised of two (2) males and one (1) female. The rabbits of the experimental lot were injected with Naja nigricollis venom for about 20 to 30 minutes and then after the determination of their biochemical and hematological parameters, were autopsied for the removal of organs such as heart, liver, kidneys and lungs. These organs were weighed and their appearance was studied. The results of this study showed that the heart and lungs of control male rabbits weighed more than those of females, whereas the liver and kidneys did not. Then, the cytotoxins of the Naja nigricollis venom were at the origin of gangrene which induced necrosis by an increase in their volume in a general way and degradation of the organs studied. Finally, the dose of venom injected (2 mg/Kg of body weight) could also cause hypotension, so favoring the formation of oedemas and consequently gangrene.

Background: Among venomous elapid snakes, cobras have the highest public awareness, as their venom represents a combination of proteins, peptides, and enzymes that have a range of biochemical and pharmacological roles and are also the main constitutes of biological activity and lethal toxicity. Objectives: The study aimed to evaluate the effect of the venom of Egyptian Spitting Cobra, Naja nubiae, on the vascular permeability based on the extravasation of the azo dye Evans blue (EB) into the tissues of the liver and kidneys of animals envenomed with low (¼ LD50; 0.32 mg/kg) and high (½ LD50; 0.65 mg/ kg) doses at three sampling times (30, 120, 360 min) post-injection of the venom. Methods: Fifty-four adult male Albino rats (8 weeks old and 180±2 0 g body weight) were divided into three main groups (n=6). In the control group, rats were subcutaneously (SC) injected with saline solution. Envenomed groups were SC injected, one group with 0.32 mg/kg and the other group with 0.65 mg/kg body weight of crude venom, respectively. Rats were I.V injected with EB dye 20 minutes before SC injection with saline solution as control animals and with Naja nubiae venom as treatment groups. Results: The results illustrated a high significant rate of EB extravasation to hepatic and renal tissues by the colorimetric determination of EB dye concentration. Conclusion: The venom of Naja nubiae can cause increased hepatic and renal vascular permeability which may explain the inflammatory effect induced by this venom.

Abstract. Title of the paper: Development of body weight in rabbits (Oryctolagus cuniculus) after embryo transfer of reciprocal nuclear combinations to a neutral line of recipients. Ihe article describes differences in the development of body weight ofthe Fl-generations in the rabbit, which oecured after embryo transfer from reciprocal nuclear combinations to a neutral line of reeipients. These differences can be explained as expression of maternal cyto-plasmatical and / or imprinting-effects. The two races – Deutsche Riesen and Farbzwerge –, which are extremly different in body weight were used for the reciprocal crosses. The neutral reeipients were a commercial breed „Zika". Results show a significant higher litter weight of the offspring which descended from the heavier mother race. On the 84th day of life exists no differences in weight between the crosses. Differences were within the crosses between the females and males and between the crosses reciprocal different. Causes for the reciprocal sexdimorphism can be A: extrachromosomal respectively cytoplasmatic factors or B: a sex-linked and a sex-influenced heredity, which coinside and are regulated by imprinting

PurposeThis research had two main objectives: To measure the productivity of companies in the Colombian dairy industry and to identify efficient decision-making units (DMUs) that can be used as work sample in future case studies.Design/methodology/approachIn the measurement of productivity, financial variables were considered for a sample of 19 DMUs. Efficient companies were identified through the data envelopment analysis (DEAs) methodology with the VRS model oriented to inputs and outputs. The input variables analyzed were “current asset,” “property, plant and equipment,” “non-current liability” and “equity,” while the output variables were “revenue” and “profit.”FindingsFindings revealed that seven DMUs are efficient in the input and output orientation and that companies of different sizes and with or without quality certifications are efficient in the sample analyzed. Additionally, the benchmark efficient DMUs were identified for each of the non-efficient DMUs.Research limitations/implicationsThe implications for the research include the contribution to the theory, on the one hand, with the analysis of the current state of the literature on the use of DEA in the food sector, and on the other, with the use of DEA to measure the productivity of Colombian dairy industry companies and with the identification of a sample of efficient units that can be analyzed in future case studies.Originality/valueThis article is novel and pioneering because it measures for the first time the productivity of DMUs of the Colombian dairy industry, in addition to including the current state of the literature on the application of the DEA methodology in the food sector. These findings contribute to the consolidation of the theory and also provide inputs for researchers, practitioners, managers, and policy makers.

Abstract We evaluated whether the GnRH application induces the sexual behavior of Dorper rams in northern Mexico (26º N). Rams (n = 12) were divided into 2 homogenous groups (n = 6 each) in body weight (80.0 ± 2.8 kg) and a body condition of (3.3 ± 0.2 units, scale of 1–5). One group (GnRH) received 100 Μ g of GnRH i.m., every 3 d x 1 week, while the other (CONT) received 0.5 ml of physiological saline solution every 3 d x 1 week. At the end of the treatments, rams were subjected to a sexual behavior test by exposing each male to one estrus female during both appetitive (ASB, anogenital sniffing, approaching, kicking, vocalizations) and consummatory (CSB: unsheathing, mount attempt, full mount, mount with unsheathing and mount with ejaculation) sexual behaviors where registered. The CSA and CSC behavior frequencies were compared by a χ 2 test (SYSTAT 12). Both ASB and CSB behaviors favored (P < 0.05) to the GnRH rams; ASB 77% vs 23% and CSB 76% vs 23%. A demonstration of GnRH in Dorper rams in northern Mexico (26 ° N) induced sexual behavior; this should be of interest to enhance the out-of-season reproductive outcomes in the sheep industry.

ABSTRACT The aim of this study was to evaluate of the efficacy of PRP employment associated with surgical sponges to improve the integration of the graft in the recipient bed. It was held at the Veterinary Hospital UNESP, Campus of Jaboticabal - SP, a study of 64 rabbits, divided into eight groups with eight animals. The groups were divided in control with saline solution 0,9%, control with PRP both without the sponge, surgical sponge with PRP, surgical sponge without PRP, and were used mesh and layer grafts in the respective groups. The data were submitted to statistical analysis (paired t-test, Kruskal-Wallis test, with subsequent use of the multiple comparison tests of Dunn, analysis of variance (F) test, Tukey test, P< 0.05). Edema and exudate with 3 and 3 and 7 days (P= 0,03 e P= 0,0049); coloring on the 14th day (P= 0,0001); cosmetic appearance on the 7th and 14th day (P= 0,0026 and P= 0,0001); mononuclear cells (P= 0,01) and polymorphonuclear (P= 0,01); fibroblast proliferation (P= 0,01); collagenous (P= 0,05); hemorrhage (P-007); necrosis and re-epithelialization (P= 0,2928 and P= 0,1). We concluded that the use of Platelet Rich Plasma Gel on skin grafts associated with a sponge as a compressive dressing promote the skin graft survival without a previous granulation tissue.

Abstract The decomposition rate and insects attraction to carcasses are affected by a number of factors such as temperature, body mass, the presence of poisons, humidity, and insect activity. The present study was planned to investigate the influence of clothing on both the decomposition process and the presence of insects on rabbit carcasses. The study was performed in May 2016 and involved the use of 18 live mature rabbits (Oryctolagus cuniculus L.), which were euthanized by chloroform. Rabbit carcasses were divided into three replicates with six rabbits in each replicate. Rabbits in each replicate were further subdivided, so that three rabbits were wrapped with cloth, whereas the remaining three were left unclothed. Both clothed and unclothed carcasses reached the dry stage within 6 d. The results of this study showed that clothes neither affect the decomposition process nor the presence of insects (flies and beetles). The pattern of flies and beetles, however, did vary significantly in the different decomposition stages. In total, 2,849 insects, including 2,459 flies and 390 beetles, were collected and sorted during the decomposition process. Among the dominant species, flies were assigned to the families Calliphoridae and Muscidae, whereas beetles were assigned to the families Dermestidae and Histeridae. Lucilia sericata Meigen, Musca domestica L., Dermestes maculatus DeGeer, and Saprinus moyses Marseul were the most abundant species occurring on both the clothed and unclothed carcasses. In conclusion, this study emphasized that, the clothes have no effect when dealing with decay process and insect attraction to the carrions.
