Abstract Phosphatidylcholine (PC) is an essential component of the plasma membrane. Its profile varies with species and tissues. However, the PC profiles in meat have not been explored in depth. This study aimed to investigate the differences in PC profiles between various meat animal species and meat cut sites, along with the identification of characteristic PC molecules. The results demonstrated that the PC profiles of chicken meat differed from those of other species. Significant differences were also observed between the PC profiles of pork meat and the meat obtained from other species. The amount of PCs containing ether bonds was high in pork meat. PCs containing an odd number of carbon atoms was characteristic of beef and lamb meats. Furthermore, PC profiles differed based on the muscle location in chicken and pork. These results suggest that the PC profiles of skeletal muscles are indicators of animal species and muscle location.

Histological and morphological characteristics of skeletal muscles in chickens of the meat direction of productivity Smena-8 and egg direction of productivity Andalusian blue on the 20th and 29th days of postembryonic development are presented. The skeletal striated muscle tissue of the studied bird obeys the general principles of myogenesis inherent in most animal species and is characterized by signs of a definitive structure. It is shown that on the 20th and 29th days of postembryonic ontogenesis in the Smena-8 cross and the Andalusian blue breed, the quadriceps femoris is ahead of the superficial pectoral muscle in terms of the thickness of muscle fibers. The thickness of the endomysium and perimysium in the connective tissue component of the superficial pectoral muscle in chickens of both directions of productivity prevails over that in the quadriceps femoris. Based on the obtained morphometric parameters of the structure of muscle fibers, the concept of myogenesis of skeletal muscles in agricultural poultry of egg and meat productivity directions is presented.

Histochemical Identification

Abstract A starch-gel electrophoretic method for the separation of esterases in homogenates of animal tissues was adapted to the histochemical identification of animal species. The method was applied to skeletal muscles of various fish species and warmblooded meat animals. Significant differences were observed in the numbers and locations of esterase bands; these differences permit the identification of the animal species. The esterase method can be successfully used in conjunction with the regular electrophoretic protein identification test for law enforcement purposes.

There are several neuromuscular disorders affecting the human being. Most of these are poorly understood and lack an effective treatment. Due to the limitation of experimental manipulation in «anima nobili», inherited neuromuscular diseases in laboratory animals constitute a valuable source of scientific information. Amongst several animal species affected by neuromuscular disorders the house mouse is of particular interest because of its small size, short pregnancy and low costs of maintanence. In the present review 20 murine mutants with diseases affecting peripheral nerves, skeletal muscles and motor end-plates are tabulated. Genetic, clinical and pathological aspects are discussed aiming to provide information about these mutants which might be of great interest as animal models for human neuromuscular diseases.

In some legal proceedings, the species identification of animal on the basis of fragments of biological material is extremely difficult. This applies both to closely-related and to distant species characterized by similar morphological features. In such circumstances, methods of molecular biology are used, whose evidential value is definitely not in doubt. Histopathological scraps may also have to be used for identifying tests. The aim of the present study was to verify the possibility of using DNA analysis in determining the species of animals on the basis of biological material contained in archival histopathological samples. The examined material consisted of twenty-eight histopathological preparations stained with hematoxylin and eosin. The samples had been prepared from the liver, kidney, spleen, and skeletal muscles. Their age varied from one to seventeen years. Specimens (from twelve species) were identified by inputting sequences in the Barcode of Life Database species identification tool on the basis of the similarity percentage figure from the BOLD report. It was found that genetic tests can effectively identify animal species through the analysis of biological material from histopathological samples.

There are conflicting reports regarding some fine structural details of arteries from several animal species. Buck denied the existence of a sub-endothelial space, while Karrer and Keech described a space of variable width which separates the endothelium from the underlying internal elastic lamina in aortas of aging rats and mice respectively.The present communication deals with the ultrastrueture of the interface between the endothelial cell layer and the internal elastic lamina as observed in carotid arteries from rabbits of varying ages.

Mixed Function Oxidase Activity

Unlike a variety of other animal species, such as the rabbit, mouse or rat, the guinea pig has a relatively long gestation period and is a more fully developed animal at birth. Kuenzig et al. reported that drug metabolic activity which increases very slowly during fetal life, increases rapidly after birth. Hepatocytes of a 3-day old neonate metabolize drugs and reduce cytochrome P-450 at a rate comparable to that observed in the adult animal. Moreover the administration of drugs like phenobarbital to pregnant guinea pigs increases the microsomal mixed function oxidase activity already in the fetus.Drug metabolic activity is, generally, localized within the smooth endoplasmic reticulum (SER) of the hepatocyte.

The fine structure of the Harderian gland has been described in some animal species (hamster, rabbit, mouse, domestic fowl and albino rats). There are only two reports in the literature dealing on the ultrastructure of rat Harderian gland in adult animals. In one of them the author describes the myoepithelial cells in methacrylate-embbeded tissue, and the other deals with the maturation of the acinar cells and the formation of the secretory droplets. The aim of the present work is to analize the relationships among the acinar cell components and to describe the two types of cells located at the perifery of the acini.
