Anatomical and Radiological Study of Interdigital Pouch of Native Goats (Capra hircus) Chahar Mahal Va Bakhtiari Province
2020
Abdi, Albert | Mobini, Behzad | Yadegari, Mehrdad
BACKGROUND: The interdigital pouch is an invagination of the skin which locates between the digits in several species of the artiodactyla. It secretes pheromones that play important biological functions in the conspecific chemical communication. OBJECTIVES: This study has been carried out in order to determine the anatomical and radiological structure of the interdigital pouch in native goats. METHODS: Eighty interdigital pouches (40 forefeet and 40 hind feet) of 10 female and 10 male, one to three-years-old, healthy native goats in slaughterhouses of Chaharmahal va Bakhtiari were selected. After dissection, topography of each pouch was determined in the feet. For radiologic studies, contrast urografin media were injected into the pouch and then radiographs and photographs were obtained. Different parts of each pouch were identified and measured between the two limbs in both sexes. Data were analyzed by t-test. RESULTS: In native goats, the pouch, which was observed in all feet, was a primitive type and located in the space between two hooves at the level of pastern joint. The pouch represents an equilateral triangle with an apex next to the first phalanx and the base near the second phalanx. The best radiographic view for pouch in native goats was dorsopalmar or dorsoplantar. Detection of the pouch in the forelimb was more than that of the hindlimb. Except for the base of pouch, the means of the other parts in male were significantly higher than females. It is difficult or impossible to define the exact radiological and topographical limits of the pouch in goat, due to the absence of secretion, excretory duct and orifice and also the dispersion of structure. CONCLUSIONS: Based on this study, it can be concluded that although the interdigital pouch has only been reported in sheep, deer, moufflon and antelope, it was also found in native goats, but it is not common.

BACKGROUND: The Eustachian tube is an osteocartilaginous channel connecting the tympanic cavity with the nasopharynx. There is no anatomical and histological research performed on this organ in buffalo. OBJECTIVES: Anatomical and histological study of Eustachian tube in buffalo will be useful for basic knowledge of this organ. METHODS: For this study 8 adult male and female buffalo's head were provided from slaughter house and their Eustachian tube were studied anatomically, then tissue samples were obtained and paraffin sections were prepared for using of staining methods such as H&E (for general study), Verhoff (for elastic fibers), PAS (for carbohydrates) and Masson's Trichrome Stainning Kit (for collagen fibers). RESULTS: Anatomical results showed Eustachian tube was white and funnel- like tube, no curve and structurally supported by cartilage and in both sexes they had the same structure. Histological and Histochemical results showed the epithelium of Eustachian tube in buffalo is pseudostratified ciliated columnar and in some regions of the Eustachian tube epithelium was stratified squamous. In the first portion of Eustachian tube cartilage was elastic and then eustachian tube cartilage was hyaline. The glands of Eustachian tube in buffalo were mucous and non folicular tubal tonsil could be found around the pharyngeal opening with obviously lymphoid tissue. CONCLUSIONS:. The results of this research can be used as the basic anatomical and Histological knowledge in buffalo..

BACKGROUND: Excretory urography is a method of imaging the kidneys, ureters, and urinary bladder which uses contrast medium containing the iodine compounds.OBJECTIVES: This study aimed to evaluate the anatomical structures of urinary tract in the nephrogram, pilogram, and cystogram phases, and determine the exact standard for the size of kidneys, ureters and urinary bladder in guinea pigs to be used to interpret the results, and clinical decisions.METHODS: This study was carried out on 10 guinea pigs with a mean age of 12±1.33 months and average weight of 1.12±0.18 kg. Before to the administration of contrast medium, each guinea pig was fast and Dimethicone 20 mg/kg was given orally. At the time of administration of contrast agent, each animal was sedated by using Ketamine 30 mg/kg and diazepam 5 mg/kg cocktail, and then 1500 mgI/kg of meglumine compound 60 % was injected subcutaneously over the shoulder area. Ventrodorsales and lateral abdominal X-rays were taken, thereafter every 5 minutes up to 60 minutes to complete the pylogram phase. In lateral radiographs of each guinea pig, the length of the body of the second lumbar vertebra was measured to be used as an indicator in determining the standard size of the kidneys.RESULTS: Based on the results of this study, the average length, width, and thickness of the right kidney compared to the length of the second lumbar vertebra were 2.19, 1.64, and 1.33 cm, and in the left kidney of 2.09, 1.53, and 1.41 cm and this average in right and left ureter was 6.41 and 6.22 cm, respectively.CONCLUSIONS: The exact standards can be used in the interpretation of results, and clinical decisions to determine the normal and abnormal size of kidneys, ureters and bladder in the guinea pigs.

BACKGROUND: Echocardiography is a noninvasive technique that is an important tool in diagnosis of cardiac diseases. Interoperation of the results of the echocardiography is dependent on having anatomical knowledge of the heart. OBJECTIVES: The aim of this study was to prepare the anatomical slices according to the related views in echocardiography. These sections can be used as a model for teaching of echocardiography. METHODS: Six dogs euthanized for purposes rather than the present study were used. The hearts were dissected and then dilated and fixed using formalin 10%. Fixed hearts were then cut to obtain representative slices corresponding to long and short axes of right parastenal standard echocardiographic views which were taken from three healthy dogs. After that, both anatomical and ultrasound images were correlated. RESULTS: The external and internal morphology of the heart were suitable for this study. The comparison of the anatomical slices with related echocardiograms showed a high level of correlation. In the long axis views, the four chambers, the atrioventricular valves and the cardiac septum were visible. The left ventricular outflow and aortic valve were represented in deeper views. The short axis series showed two ventricles and their internal morphology. CONCLUSIONS: The slices of hearts which were fixed using formalin may be used for echocardiography interoperation

BACKGROUND: Reptiles, especially turtles that inhabit both on land and water, have made some special adaptations. Many people keep turtles as pets. Therefore, the anatomical knowledge of turtles should be more carefully evaluated and used for therapeutic purposes. One of these turtles is European pond turtle (Emys orbicularis). Most of vital systems are enclosed by the carapace and the plastron so it cannot be examined customarily by clinicians. The noninvasive diagnostic imaging techniques provide detailed information concerning these organs. OBJECTIVES: This study was conducted to give complete topographic information and knowledge about the position of the non respiratory organs of the coelomic cavity in the European pond turtle using Computed Tomography (CT) and usual anatomic methods. METHODS: 10 adult turtles (5 female, 5 male) were selected. All scans were obtained on a two detector scanner. In anatomical study three female and three male turtles were dissected. Two other female and male turtles were sectioned transversely. RESULTS: The results showed some differences in the position of the organs including stomach, gall bladder, liver and heart with those of other species. Moreover, the topography of the organs is described in retracted and protruded neck in this article. Retraction of the neck had an influence on the position of the organs such as oesophagus, stomach, liver and heart. CONCLUSIONS: The general morphological features of the non respiratory organs of the coelonic cavity of European pond turtle were examined by CT images and macroscopically in this study. Significant differences were found compared with other species.

BACKGROUND: One of the important parts of the cardiovascular system is the cardiac vessels. Ultrasonography which is the method of choice for evaluating the heart and vessels in all living animals can also be used in this fish. OBJECTIVES: This study was conducted to make a full understanding of the anatomic and echocardiographic characteristics of these vessels in beluga and suggest standard methods of ultrasonography for this species. METHODS: In this study, a total of 10 immature belugas were selected. The transducer was placed on the ventral surface of the body, between pectoral fins and transverse and sagittal images were obtained. By moving the anterior and posterior regions the vessels were investigated. After the ultrasound examination, anatomic studies were performed. Length and diameter of the vascular compartment were measured and analyzed by SPSS 16 software and Paired Sample T – method (P>0.05). RESULTS: In ultrasonography, blood flow was visible because of the movement of echoic particles. Two precardiac vessels joining between the liver lobes constituted and common vascular compartment before entering the sinus venosus. In the anatomical study, the ventral aorta was bifurcate near the gills. The right liver adjacent to the vessel was shorter and wider than the left one. Moreover, the common vascular compartment was shorter and wider than the liver adjacent to the vessels. The ventral aorta was longer and wider than the right precardiac vessel and common vascular compartment but was shorter than the left precardiac vessel (P>0.05). CONCLUSIONS: Due to lacing thorough anatomic and ultrasonographic studies concerning the cardiac vessels in this species, this study can be a cornerstone for further researches of this kind. In this study the long left precardiac vessel is named Common cardinal vein and wide right vessel is named Hepatic vein.

BACKGROUND: Cryptorchidism is a congenital anomaly in which one (unilateral cryptorchidism) or both (bilateral cryptorchidism) testes fail to descend into the scrotum. OBJECTIVE: The aim of this study was to describe the anatomical and histological structure of the inguinal testis in the adult donkey. METHODS: In this study, after examination of the 59 donkeys, three of them with unilateral cryptorchidism in inguinal region were identified. These animals were euthanized, and their testicles were removed and evaluated biometrically. Then, the samples were fixated in 10% formalin solution and after sectioning, were stained with Hematoxylin-eosin and PAS, and examined under a light microscope. RESULTS: The results showed that the inguinal testes were stiff, epididymis was not determined and their size and weight were less than scrotal testes. The difference between the weight of cryptorchid and healthy testicles was statistically significant (p<0.05). Seminiferous tubules had lost their natural shape and inner cavity tubes did not have germ cells, and only a limited number of Sertoli cells could be seen. Remaining seminiferous tubules were only visible in the mediastinum. The cortical and subcapsular regions were without tubes and were occupied by loose connective tissues. CONCLUSIONS: Results indicated that the inguinal testes in adult donkeys lost their natural structure and more connective tissues and blood vessels are substituted.

Tibbo, Markos | Jibril, Y. | Woldemeskel, M. | Dawo, F. | Aragaw, K. | Rege, J.E.O.
Hematological parameters were studied in 163 apparently healthy goats comprised of 3 indigenous breeds at Adami-Tulu Agricultural Research Centre (ATARC) and Sheno, Agricultural Research Centre (SARC), Ethiopia. Data were analyzed for the effect of breed, sex, age, and season. Hemoglobin (Hb) was significantly higher (P < 0.0001) for Arsi-Bale (AB) than Longeared Somali (LES) and Central Highland (CH) goats. Packed cell volume (PCV) was significantly lower (P < 0.0001) for LES than the other two breeds. White blood cells (WBC) (P < 0.05), neutrophils (P < 0.0001) and basophils (P < 0.0001) were higher in CH than in the other two breeds. Conversely, lymphocytes were lowest (P < 0.0001) in CH goats compared to other breeds. Female goats had significantly (at least P < 0.05) higher red blood cells (RBC), PCV, WBC, lymphocytes and eosinophils than male goats. In contrast, males had higher (P < 0.05) mean corpuscular hemoglobin (MCH) and neutrophils than females. There was no significant age difference for the erythrocytic series but the age difference was highly significant (P < 0.0001) for the leukocytic series. WBC and lymphocytes decreased as age increased while the reverse was true for neutrophils and eosinophils. Seasonal variation was also considerable for both erythrocytic and leukocytic series. RBC, Hb, lymphocytes, and neutrophils of the indigenous goat breeds were remarkably different compared to most other exotic goat breeds.

This study aimed to determine the anatomical and histological structure of the uterus of the Anatolian wild goat. Measurements were taken from the uterine segments using digital callipers. The animal material consisted of three wild goats of similar ages (2-3 old). The uterus was studied in three sections: Corpus uteri, cornu uteri and cervix uteri. Each section was examined anatomically and histologically.The mean length of cervix uteri was 33.99±1.22 mm, width of the cervix uteri was 13.39±0.92 mm, thickness of the cervix uteri was 8.42±1.68 mm and weight of the cervix uteri was 5.45±0.80 g. The mean corpus uteri length was 29.61±5.14 mm, corpus uteri width was 21.22±1.98 mm, corpus uteri thickness was 9.05±1.45 mm and corpus uteri weight was 4.30±0.77 g. The mean cornu uteri length was 41.34±8.02 mm, the cornu uteri width was 12.49±2.59 mm, the cornu uteri thickness was 6.73±0.86 mm and the cornu uteri weight was 5.46±0.31 g. Histologically, the uterine tissue was consist of three different regions, namely, cervix uteri, corpus uteri and cornu uteri also this parts were composed of endometrium, myometrium and perimetrium layers were located from the inside to the outside.The findings of this study related to the Anatolian wild goat, which contributes to the wildlife diversity in Turkey, however, the population of which has been decreasing due to illegal and uncontrolled hunting or traffic accidents in recent years.

This study was to examine the opinions of first-year veterinary faculty students about the use of plastinated anatomic prosections in addition to wet cadavers in anatomy practical lessons. The students were shown plastinated organs and organs fixed in formaldehyde. Then a questionnaire comprising 7 questions was administered to the 100 student participants. The questionnaire responses were analyzed statistically using SPSS vn. 22.0 Frequencies software.In response to question 1, 58.4% of the students thought that there was no anatomic difference between the plastinated organs and the organs fixed in formaldehyde. In contrast to the strong smell of formaldehyde, 88% of the students stated that the plastinates were odourless. The use of plastinated organs was thought to improve the quality of education by 89.1% of the students, compared to the negative aspects of formaldehyde. It was stated by 84.2% of the students that plastinated organs should be included in anatomy lessons due to the thoughts of the majority of the students that plastinated tissues could make a greater contribution to anatomy lessons. In response to the final question, 92.1% of the students stated that they felt no abhorrence of the plastinated organs.Plastination may be especially useful for educational institutions without access, space, or the financial resources for dissection, and can emphasize unique or pathological samples. The results of this study demonstrated that plastinated samples were perceived as a useful addition to traditional resources in the teaching of anatomy.
