AIM: The aim of the study is to create a myringoplasty technique with decellularized matrix of xenoperitoneum in an experiment on rabbits with morphological rationale of a new biological material application.  METHODS: Sixty rabbits were included in research. The animals were randomly divided in two groups for use the bioimplant – decellularized matrix of xenoperitoneum and control. Each subgroup corresponded to the observation period and the removal of the animal from the experiment. Observation period was: 7 days, 21 days and 30 days after myringoplasty. RESULT: The maturation of connective tissue in both groups was completed by the 30th day. But the change in the exudative phase into the proliferative phase occurred faster and the dynamics of reparative processes after myringoplasty were better in experimental group. CONCLUSION: The use the decellularized matrix of xenoperitoneum had better reparative properties

In the following experiment proved the possibility of the use of medical adhesive "Sulfacrylate" for efficient seamless testicular fixation to the tissues of the scrotum. Rabbits were di vided into 2 groups. 3 rabbits (6 testicles) were the control group. The adhesive was spread on the whole surface of the rabbits' testis in this group Experimental group consisted of 13 rabbits (26 testes), in which the adhesive is applied in dot and control conducted in 15, 30, 90 and 180 days. Macroscopic and microscopic picture of the local area of the testis' adhesive fixing is characterized by a strong fixation of the scrotum and the absence of adhesions in the surrounding tissues. By 30 days fixation spot is presented with granulation tissue with organization signs, and by 90 and 180 days compounds zone has the form of a mature connective tissue with clearly limited size and without any adhesions in the surrounding tissues. Key words: testicles, fixation method, experiment

This study was aimed at finding out The Effect of Applying POSSE (Predict-Organize-Search-Summarize-Evaluate) Strategy on the Students’ Reading Comprehension. This study used the experimental design. The population of this study was the students of SMA Negeri 2 Medan. There were sixty students taken as the sample of the research. This study was conducted with two randomized groups namely experimental and control group. The experimental group was taught by applying POSSE strategy while control group was taught without applying POSSE strategy. The instrument of collecting the data was multiple choice test which consists of 40 items. To obtain the reliability of the test, the researcher used Kuder-Richardson (KR-21). The calculation shows the reliability was 0.81(high). The data were analyzed by using t-test. The calculation shows that t-observed (4.76) is higher than t-table (2.00) at the level of significance (α) 0.05 with the degree of freedom (df) 58. Therefore, the null hypothesis (Ho) is rejected and alternative hypothesis (Ha) is accepted.

The problem of this study is “Does Concept Oriented Reading Instruction (CORI) enhance students’ reading achievement?” The design of this study was quasi-experimental. The sample of this study was taken from the population by using purposive sampling. The experimental group consisted of 39 students while the control group consisted of 35 students. The data were collected by using two instruments; test and questionnaire. The test was given twice to each group in order to see whether or not there was significance difference of pretest and posttest either in experimental or control group and whether or not there was significance difference of experimental and control group in terms of their posttest score. To prove the hypothesis, the data from pretest and posttest of experimental and control group were analyzed by applying paired sample t-test and independent sample t-test. The calculation was run by using SPSS computer program. The result of the study shows there was significance difference of students’ reading achievement between experimental and control group. Besides, the use of CORI as reading strategies was proved as effective reading strategies to enhance students’ reading achievement.

The purpose of the research is studying the efficacy of Eprimek (Eprinomectin) against gastrointestinal nematodes in sheep.Materials and methods. A commercial experiment to study the antiparasitic efficacy of Eprimek was carried out in June 2020 on 300 lambs of the North Caucasian breed in a private flock of Filimonovskaya Village, Izobilnensky District, the Stavropol Territory, which were divided into two groups. The experimental group of lambs (290 animals) was injected Eprimek subcutaneously at the earset at a dose of 1 ml/50 kg of live weight (10 mg of Eprinomectin in 1 ml), and 10 lambs were not treated; they were used as control. We collected feces from the lambs of the experimental and control groups before administration of the drugs and after 15 and 30 days. Fecal samples were examined by the flotation technique with a saturated solution of ammonium nitrate with counting nematode eggs in 1 g of feces. The results were processed statistically.Results and discussion. Eprimek showed a decrease in the number of excreted helminth eggs from 225.1±28.2 to 4.1±2.3 in production environment at a dose of 1 ml/50 kg of live weight, according to coprological studies on the 15th day after treatment in the experimental group of lambs. The efficacy was 98.2%, and 70% of the animals were free from the infection. The intensity of infection of the control lambs by gastrointestinal nematodes was 131–151 eggs per 1 g of feces at 100% prevalence.
