Background: Cuscuta epithymum (CE) is an established medicinal herb utilized for treating psychosis in Persian medicine. The aim of this study was to investigate the effect of CE combined with risperidone on the clinical symptoms and the cognitive impairment in patients diagnosed with schizophrenia. Materials and Methods: In this triple-blind randomized placebo-controlled trial, the intervention group received a dose of 500 mg of CE in the form of a capsule to be taken twice a day accompanied by an appropriate dose of risperidone. The control group was presented with a placebo identical to that of the CE capsule plus the allocated dose of risperidone. The PANSS and SCoRS questionnaires were used to assess the status of subjects prior to the initiation of the intervention as well as being put to use at the end of the second, fourth, and eighth week post-intervention. Registering and recording intel concerning positive and negative symptoms felt by participants (PANNS), and a test to assess the cognitive impairment of the individuals. Results: After eight weeks of treatment, all negative and positive symptoms besides hostility and somatic concern exhibited a significant improvement in the CE group (P <0.05). In contrast, the CE placebo group displayed no substantial improvement in the cases of the positive, negative and general symptoms (P>0.05) regarding cognitive impairment, after eight weeks of treatment, all symptoms were greatly improved in the CE group (P<0.05), while the effect of the placebo on the patients cognitive impairment remained mostly stationary (P>0.05). Consequently, after eight weeks after the intervention, we can determine that the CE treatment has been noticeably more effective at improving positive, negative and cognitive symptoms of patients with schizophrenia. Conclusion: The results of this study demonstrated that CE, possessing possible antioxidant and neuroprotective properties, safely improved the positive and negative symptoms, and cognitive impairment of patients with schizophrenia.[GMJ.2019;8:e1334]
THE CHANGES IN BLOOD PARAMETERS OF COWS INFECTED BY LEUCOSIS IN CASE OF COMPLICATIONS WITH ACUTE ANAPLASMOSIS
Authors: Loginov S. I. 
Published: December 2019

The authors found out that some districts of the Tomsk region are unfavourable in respect to bovine anaplasmosis. In enzootic areas with bovine anaplasmosis the bovine leukemia was observed in susceptible animals. The research focuses on hematological and immunological changes of the blood of cows infected with leukemia during the acute anaplasmosis. That was found out in spring while intense activity of ixodids (the end of April). The researchers arranged two groups of Black-and-White cows aged 2.5-3 years infected with leukemia virus. The 1st group was infected with acute anaplasmosis cow leukemia virus, the 2nd group (control) was infected with anaplasm-free cow leukemia virus. The changes in the hematological pattern of cows infected with leucosis in case of complications with acute anaplasmosis consist in eosinophilia, neutropenia, lymphocytosis and monocytopenia. The changes in the immune system of cows were less noticeable and characterized by a moderate increase in IgG and high titers of antibodies to leukemia virus. The researchers assume that there is a significant sensitization of the humoral component of the immune system of cows infected with leucosis in case of complications with acute anaplasmosis. The noticeable lymphocytosis in the certain cows infected with leukemia virus in case of complications with acute anaplasmosis should be taken into account when making a diagnosis for cattle leukemia. This occurence in the hematological picture of blood can be characterized as a temporary leukemia reaction, causing a false positive result of hematological test on leukemia.

Published: December 2019

The article discussesthe current problem of food quality control, the content ofstrontium-90 and cesium - 137 in the body of wild game birds-wild game inhabiting the territory of the Republic of Sakha (Yakutia). The object for research were carcasses of wild game 3 species: black grouse; partridge; grouse. Radiation safety of wild game as a food product was determined by its compliance with permissible levels of specific activity of radionuclides, in particular 137Cs and 90Sr. These indicators are regulated by TR CU 021/2011 “on food safety”. According to the long-term (2013-2017) results of our studies 137Cs and 90Sr in carcasses of wild game, Northern, Central, Vilyuisk and southern ecological zones of the Republic of Sakha (Yakutia) was not found to exceed the permissible concentration. As a result of our research, the following results were obtained: the content of 137Cs and 90Sr in grouse carcasses: southern - 70.54±0.71 and 26.43±2.54; Central-64.81±0.18 and 20.89±1.95; Vilyuiskaya - 73.12±0.01 and 28.48±1.18. Black grouse does not live in the Northern ecological zone. The results of the study of partridges are as follows: South-69.04±2.95 and 28.17±0.05; Central - 58,69±2,18 19,87 and±0,39; Vilyui - 70,84±1.55 and 27,87±0,04; North - 28,17±0.05 and of 10.83±0,50. In the study of grouse is established: the content of radionuclides in the southern zone - 71,24±1,95; Central was 60.05±0.01 and of 21.11±1,95; Vilyui - 71,11±0.55 and of 11.47±0,32. According to the results of our studies, the data of exceeding the maximum concentration of 137Cs and 90Sr in the carcasses of wild game in all ecological zones of Yakutia were not established.
MORPHOLOGY OF BRACHIAL PROFUNDA ARTERY OF THE DOMESTIC REINDEER’S THORACIC LIMB IN ONTOGENESIS

Published: December 2019

The authors argue the reindeer’s vascular morphology is not sufficiently investigated. They focus on the distal part of the thoracic and pelvic limbs, which the reindeer steps on the ground and hurts it often, as it leads to necrobacterial lesions in summer. In the postnatal period of the reindeer growth, the most intensive one in the length and diameter of the main arteries is observed in the first year, especially in the first month. During this period, the newborn deer gets into the new conditions of existence and the organs of movement become more and more functional. By the age of 3 - 3.5 years, the growth of the main arteries in length is almost over. The paper explores the features of blood supply of the thoracic limbs of a domestic reindeer, caused by the prominent growth of the second and fifth fingers. The absolute growth of arterial length in newborns and deers aged 0.5 months is 0.6 cm per day. In the following years of life, the length is reduced to 0.03 cm in the reindeers aged 3 y.o. The relative diameter of the arteries to the limb length in the postnatal period decreases from 4.4% in newborns to 3.3% in old deer. The irregularity of changes in the absolute and relative development of the thoracic limb arteries can be explained by different growth of blood vessels, bones, joints and limb muscles.
GROUNDS FOR THE DEVELOPMENT AND APPLICATION OF PRECISION TECHNOLOGIES IN ORDER TO KEEP SPECIFIC BEEF CATTLE UNDER THE CONDITIONS OF YAKUTIA
Authors: Sleptsov I. I. 
Published: December 2019

The article demonstrates the research results on climate conditions of the Republic of Sakha (Yakutia) and grounds of application of precision technologies for breeding Kalmyk beef cattle on the basis of specific natural and climate conditions of Yakutia. The history of animal breeding says that enhancement of local livestock’s producing qualities in different years contributed to the fact that the stud breeds of cattle, generally dairy and beef-dairy types, were imported. Animals of the beef productivity type, known as Kazakh Whitehead cattle, the Hereford, the Kalmyk, and the Calloway breeds, were imported in order to receive crossbred youngsters with improved feeding and beef parameters. In all the time of the development, the cattle breeding in the region had beef-dairy types. The beef breeds were imported in the last decade for targeted purebred breeding and development of the beef industry for production of the beef. Therefore, in 2012, there were imported 200 animals of the Hereford cattle; the Kalmyk breed has been imported since 2013. The experience has shown that naturalizing of purebred animals to the breeding conditions of Yakutia was extremely stressful, and was followed by the diseases, falls, and decreasing of seed stock’s reproductive indicators. Particularly negative impact was observed on the animals of the highly productive Hereford breed, and this caused gradual degeneration of the breed under conditions of Yakutia. Although, specific natural and climate conditions of Yakutia significantly differ from that in other regions with developed beef cattle breeding, the animals of the Kalmyk breed, which was bred on the basis of the native steppe cattle, were relatively well adapted to the harsh conditions of the region. The authors argue the necessity and urgency of adaptive technologies development on specialized beef cattle breeding with respect to the harsh local conditions.

Published: December 2019

Penelitian ini bertujuan untuk mengetahui seberapa besar pengaruh aktiva lancar dan modal sendiri terhadap profitabilitas. Penelitian dilaksanakan pada PD. Sri Tanjung Kabupaten Indramayu. Data diperoleh dari Laporan keuangan dalam bentuk neraca dan laporan laba rugi dari tahun 2010 sampai dengan tahun 2015.
Berdasarkan dari hasil analisis data yang diperoleh koefisien korelasi X1 terhadap Y sebesar 0,081 yang berarti bahwa perolehan aktiva lancar terhadap profitabilitas mempunyai hubungan positif dan keeratan hubungan termasuk dalam kategori sangat tinggi. Koefisien korelasi X2 terhadap Y sebesar 0,647 yang berarti pula bahwa perolehan modal sendiri terhadap profitabilitas mempunyai hubungan positif dan sangat kuat. Koefisien korelasi antara X1 terhadap X2 sebesar 0,903 yang berarti bahwa perolehan aktiva lancar terhadap modal sendiri mempunyai hubungan positif dan sangat kuat.
Nilai koefisien determinasi (Kd) yang diperoleh dalam penelitian ini dari X1 terhadap Y diperoleh hasil sebesar 33,80%, hal ini menjelaskan bahwa perolehan aktiva lancar terhadap profitabilitas usaha sebesar 33,80%, sedangkan sisanya sebesar 66,20% yang merupakan faktor-faktor lain yang mempengaruhi profitabilitas. Pada X2 terhadap Y diperoleh hasil sebesar 41,86% hal ini berarti menunjukkan adanya modal sendiri memiliki pengaruh terhadap profitabilitas sebesar 41,86% yang sisanya sebesar 58,14% dipengaruhi oleh faktor-faktor lain yang mempengaruhi profitabilitas
Untuk melihat ada tidaknya pengaruh antara aktiva lancar terhadap profitabilitas maka digunakan uji hipotesis dengan membandingkan thitung dengan ttabel. Untuk melihat pengaruh aktiva lancar terhadap profitabilitas hasil yang diperoleh dalam Uji t dimana thitung lebih kecil dari ttabel (1.115 < 2.776) dan tingkat kesalahan mencapai 5%. Artinya tidak ada pengaruh aktiva lancar terhadap profitabilitas. Kemudian untuk pengaruh modal sendiri terhadap profitabilitas hasil yang diperoleh dari Uji t yaitu dimana thitung lebih kecil dari ttabel (1.967 < 2.776), artinya tidak ada pengaruh modal sendiri terhadap profitabilitas.
