All the surface cells of the gastric mucosa and in the crypts were positive on the PAS reaction and negative in the case of the alcian blue reaction. This demonstrates that cells on the surface and in the crypts synthetize neutral mucins. In the case of the cardiac region glands, only a small number of cells were positive on the two histochemical reactions, which shows that the cardiac glands in guinea pig synthesize a very small amount of neutral and acidic mucins. There are no positive cells in neither reaction used in the fundic glands case, which shows that these glands do not synthesize mucins, neither neutral nor acidic content. The glands located in the pyloric region have cells in the deep half of the wall which were positive on both histochemical reactions, which shows that they synthesize both neutral mucins and acidic mucins.","PeriodicalId":9406,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture","volume":"77 1","pages":"115"},"PeriodicalIF":0.0,"publicationDate":"2020-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47041911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total number of 5 dogs, aged between 7 months and 6 years old were clinically evaluated for gastro-intestinal problems that lead to the suspicion of apparent intestinal dysbiosis. The probiotic administration respected the producer recommendations and it was given to the dogs together with their usual food, one capsule/day, 30 days consecutively. On the first and 31 days of the study, blood samples were collected and hematological parameters were evaluated. A heterogeneity in the hematological results was observed. However, when results from day 0 were compared with results obtained in day 31, the variance was considered to be physiological. Also, the small diferences between the values before and after the treatment can not be attributed only to the probiotic treatment. The results obtained regarding the dynamics of the hematological parameters provided data that sustain the benefic effect of this probiotic combination, without a direct impact on hematological parameters.","PeriodicalId":9406,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture","volume":"77 1","pages":"72"},"PeriodicalIF":0.0,"publicationDate":"2020-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47990426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the paper is to provide data on the bone structure of animal species involved in dental research, highlighting the complexity of bone structure and osseointegration depending on the species. At the same time, the importance of selecting animal models is emphasized, in order to obtain the most accurate data for the development of dental implants and their use in humans. Following the research, essential data were obtained that helped to synthesize the bone characteristics of animals such as rats, rabbits, pigs, sheep or goats and relate them to the human bone skeleton. These data are useful in choosing an animal model when testing a new dental implant.","PeriodicalId":9406,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture","volume":" ","pages":"1"},"PeriodicalIF":0.0,"publicationDate":"2020-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.15835/buasvmcn-vm:2020.0020","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42937417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is also among the most prevalent zoonotic diseases with special importance for public health that causes drastic financial losses in both developed and developing countries.

Thus, an epidemiological survey was conducted on sheep hydatidosis during 5 months between December 2017 and April 2018 at three slaughterhouses of M’sila governorate, situated in municipalities of M’Sila, Boussaâda and Sidi Aissa. In parallel, an epidemiological investigation via interviews and questionnaire was conducted from March to April, 2018 on a sample of 46 sheep breeders located in M’Sila region. The questionnaire treated several risk factors (presence and deworming of dogs, informal slaughtering practices, fiability of preventive measures... etc.). Results showed a general prevalence of 24.80% among 9048 slaughtered sheep, and a seasonal prevalence higher in spring (42.02%) than in winter (21.65%) (p>0.05). Sheep of five to six years old and more are the most parasitized (p<0.0001). The lungs (38. 24%) and the livers (30.39%) were the most affected organs, while 31.24% of sheep were affected simultaneously in both organs (liver and lungs).

For this purpose, the combination of a mercury chloride fixator (Stieve mixture) and a complex staining method (Goldner’s trichrome) was used, which can highlight the microscopic structures in several colors and shades. The Stieve mixture proved to have distinguished qualities both in the preservation of basophilic and acidophilic structures and especially in the chemical preparation of the substrate for the binding of each structural component with a specific acidophilic dye. On the substrate thus prepared, the acidophilic dyes used in the Goldner’s trichrome staining highlighted the structural components in different colors and shades, offering the possibility of high precision assessment of the newly proliferated bone, in different stages of proliferation, consolidation and reshaping. Complex information was obtained, which allows the appreciation of osseointegration for endosseous implants and the amount of proliferated bone at the boneimplant interface, the stage of proliferation, consolidation and reshaping of the mature bone, the degree of fixation to deep bone structures. The possibility of complex assessment of the osseointegration process for endosseous implants at a given time is of great practical importance for correct assessment of the waiting time required for safe installation of prosthesis. The combination of Stieve fixator mixture with Goldner’s trichrome staining method has proven to be very effective in histology, highlighting on excellent level the existing structural components of each stage, in which the osseointegration process goes through. A very important role in this combination was achieved by mercury chloride mixture, which prepared the substrate for specific reaction with dyes.
