Authors: Kalmin O.V., Koretskaya Е.А., Zyulkina L.A.
Organization: Penza State University
Summary:

Aim is to analyze the dimensional characteristics of the width of the periodontal fissure in the teeth of the upper and lower jaws with increased tooth abrasion in adults. Material and Methods. 204 people of both sexes aged 22 to 60 years were served as the object of the study. Using cone beam computed tomography, the width of the periodontal fissure was studied at the level of transition of the upper third to the middle third of the root, at the level of transition of the middle third of the root to the lower third, and at the level of the apex of the tooth root. In the upper molars, the measurements were performed at the palatine root, in the molars of the lower jaw — at the distal root. Results. The dimensional characteristics of the width of the periodontal fissure on both jaws statistically significantly increase from the first period of adulthood to the second in persons of both sexes: in men at the level of the upper third of the root by 12.5-96.3%, the middle third —11.8-78.6%, tops of the tooth root —22.2-106.7; in women —by 2.4-65.8, 3.0-22.0and 19.1-93.6%, respectively. Conclusion. The results of the study indicate that the width of the periodontal fissure is not the same in different parts of the root, varies depending on the functional load and does not depend on the group affiliation of the tooth. The width of the periodontal fissure at the level of transition of the upper third of the root to the middle third, the middle third of the root to the lower third and in the region of the apex of the root in the teeth on the lower and upper jaw, statistically significantly increases from the first period of adulthood to the second in both men and women.

Summary:

Objective: to determine the features of peri-implant tissues healing in conditions of tobacco intoxication and the possibility of their correction by using electromagnetic terahertz radiation at the frequency (EMR THF) of 129.0 GHz. Material and Methods. 36 rabbits were divided into control group and three experimental ones. In the experimental groups, tobacco intoxication was simulated for 6 weeks, then implantation was performed and tobacco intoxication was maintained until the end of the experiment. In the 1st experimental group, physiotherapy was not performed; in the 2nd and 3rd groups, various schemes of THF therapy were used. The results were evaluated using histological methods. Results. In the control group, the most active regeneration processes were noted. Among the experimental groups, the best indicators were achieved in the groups where THF radiation was used. The thickness of the connective tissue layer after 1 month was significantly lower in the 2nd and 3rd groups, amounting to 48.0±3.9 and 42.7±3.4 urn, respectively, than in the 1st group: 76.4±3.5 urn (p<0.05), this dynamics continued after 3 months. Osteogenesis in the 2nd and 3rd groups took place with less cartilage formation than in the 1st group (p<0.05). Conclusion. Analysis of histomorphom-etry data shows the effectiveness of THF therapy for the correction of the regeneration process violations after dental implantation in conditions of tobacco intoxication.

Morphological changes of tissues in the zone of implantation of combined hernia prosthesis in the post-operative period

Year: 2017, volume 13 Issue: №3 Pages: 458-461
Heading: Macro- and Micromorphology Article type: Original article
Authors: Kalmin O.V., Nikolsky V.I., Fedorova M.G., Feoktistov Ya.E.
Organization: Penza State University
Summary:

The purpose of this experimental study is to study the patterns of morphological response of the abdominal wall tissues to the implantation of a combined (xenopericardial plate and polyester mesh) hernia prosthesis. Material and Methods. The experiment was carried out on fifteen rabbits of the breed Chinchilla weighing up to 3.5kg. The combined prosthesis was implanted intra — abdominally. The animals were withdrawn from the experiment after 2 weeks, 1 month and 2 months. After the beginning of the study morphological and morphometric assessment of the tissue state in the implantation zone of the prosthesis was carried out. Results. The combined hernia prosthesis when implanted into the anterial abdominal wall causes a rather pronounced inflammatory reaction, progressing within a month after the operation. By the second month of the experiment, signs of inflammation decrease. In this case, active growth of the young connective tissue in the implant from the side of the polyester mesh occurs. Xenopericardial plate, facing the abdominal cavity with a smooth side does not cause the formation of connective tissue, which protects the abdominal cavity from the occurrence of adhesions in the postoperative period. Conclusion. The use of combined hernia prosthesis for implantation into the abdominal wall allows avoiding a number of complications which often occur when using prostheses of other types.

Summary:

Objective: to determine the characteristics of the outcome of the improper care for children, established during the commission of forensic examinations. Material and Methods. The material of this study was commission a forensic medical examination of the archives department of complex expertise of the Bureaus of Forensic Medicine of Moscow; the Moscow, Penza, Samara and Ulyanovsk regions, and the Republic of Mordovia, conducted from 1996 to 2006. The method of this study was a statistical database processing using Excel software application package. Results. The article presents the results of the analysis of 279 forensic medical examinations conducted by committees in the Bureaus of Forensic Medical Examination of Moscow; the Moscow, Penza, Samara and Ulyanovsk regions, and the Republic of Mordovia from 1996 to 2006. The examinations were conducted in connection with poor outcomes of rendering medical care to children. Conclusion. The number of conducted examinations correlates with the population of the region. The parents of the children affected by poor treatment mostly demand the medical staff to be prosecuted and more often make legal claims to the quality of emergency medical care; dissatisfaction with the quality of medical care is more often expressed by the parents of children under 3 years old. Legal claims are more often made against obstetricians-gynecologists, pediatricians, surgeons, infectious disease specialists and anesthesiologists-resuscitators. If the conclusion of the forensic medical examination committee on the nature of the pathological process coincides with the final clinical diagnosis, the provided medical care often turns out to be adequate; in cases of inadequate medical care the risks of moderate and grievous bodily harm as well as the patient's death are high.

Summary:

Objective: to identify the microscopic features of the structure of the thyroid gland in different forms of its pathology. Materials and Methods. The study is based on the thyroid glands of 199 patients of both sexes aged 21 to 74 years. Results. At the micro-macrofollicular nontoxic goiter was found flattened thyroid epithelium with flattened normochromic nucleus, the small size of cells and nuclei, low nuclear-cytoplasmic index, intrafollicular moderate epithelial proliferation, homogeneous colloid and moderate diffuse lymphoid infiltration. At the micro-macrofollicular toxic goiter detected cubic epithelium with rounded normochromic kernel, smallest size of cells and nuclei, nuclear-cytoplasmic minimum index intrafollicular focal proliferation of the epithelium, colloid mesh boundary with severe vacuolization, focal lymphoid infiltration and hemorrhage. When diffuse toxic goiter detected cubic form cells of medium size with a fairly high nuclear-cytoplasmic index, rounded normochromic kernel, rare intrafollicular epithelial proliferation, homogeneous colloid with an edge vacuolization. With the prevalence of autoimmune thyroiditis was observed flattened epithelium with rounded normochromic nucleus, the small size of cells and nuclei, found the average nuclear-cytoplasmic index, homogeneous colloid and extensive lymphoid infiltration with light propagation centers. Adenoma of the thyroid gland epithelium was found with a cubic cell shape, round hyperchromatic nucleus, the large size of cells and nuclei, high nuclear-cytoplasmic index intrafollicular diffuse proliferation of epithelial and dense colloid. When thyroid cancer found the prevalence of papillary structures with short broad papillae formed polymorphic cells with round hyperchromatic nucleus, there is the largest size of cells and nuclei, nuclear-cytoplasmic maximum index expressed intrafollicular diffuse proliferation of the epithelium.

Heading: Macro- and Micromorphology Article type: Original article
Authors: Kalmin O.V., Nikishin D.V., Volodina Yu.M.
Organization: Penza State University
Summary:

Objective: to evaluate the efficiency of a resorbable membrane «Bio-Gide» in combination with chitosan for guided bone regeneration during the degradation under the experimental conditions. Material and Methods. The histological methods provide the study of tissue samples from 6 adult rabbits from artificial mandible through 14, 28 and 42 days after surgery. In group 1 the treatment was carried out without the use of additional materials, by a blood clot. In group 2 closing of the damaged area was produced by xenopericardial plate «Bio-Gide» in combination with chitosan. Results. It has been established that the conduct of bone wound under a blood clot causes inflammatory response on the 14th day after the operation, to the 28th day inflammation disappears and it practically does not appear on the 42nd day. Closure of the bone defect using xenopericardial plate «Bio-Gide» with chitosan causes lesser inflammatory response. In the long-term period after the surgery inflammatory changes in the implantation can not be detected. Conclusion. Xenopericardial plate «Bio-Gide» in combination with chitosan has a positive impact on the recovery process of the bone defect. Neoplasm of bone occurs, the stage of development of cartilage is shortened. At the end of the experiment period xenopericardial plate is not detected indicating the high rate of its biodegradation.
