In a subchronic experiment with intramuscular injection in rats, it was found that a dose of 70,7 mg/kg is toxic, and doses of 35,4 and 17,2 mg/kg are inactive (safe). It was noted that the 14 day administration of the drug «Ketoprofen 10%» in a dose 70,7 mg/kg caused a decrease in the body weight of experimental animals, contributed to the development of hepatotoxic action, a change in the mass coefficients of internal organs. The above effects were reversible 10 days after discontinuation of the study drug.

The toxicity parameters of “VetMikoDerm” for one-time and long-term skin treatment were investigated. The studied liniment as an off-white substance has a thio derivative of 1,2,4-triasole.  Spotted thistle oil is used as a solvent. The research of the determination of acute and low acute skin toxicity has been performed on young, healthy, healthy skin of the laboratory rats. The drug was applied in different doses to the stripped areas of the skin (area is not less than 10% of the total area of the skin). It was established that after a single application of the drug (24 hours) in a dose of less than 2000 mg/kg of body weight, the death of experimental animals or any signs of general intoxication of the body is not observed.  Local reaction (redness, itching, allergy, combing) is absent. According to GHS under the assessment in this dose studying the “VetMicoDerm” drug belongs to the 5th safety category (Grade 5, not classified). During a long-lasting application of the drug (28 days), the death of the rats was not adversed, the animals had a preserved appetite, responded adequately to external stimuli, reflex excitability was completely preserved.  Under hematological and biochemical studies of blood of the experimental animals, it was found that against the backdrop of insignificant increase in the number of white blood cells in their blood, the number of neutrophils increases and the percentage of lymphocytes decreases significantly. However, under the usage of the drug in the therapeutic dose (50 mg/kg body weight) the liver function has a tendency to increase. Increasing in dose (500 mg/kg) of the VetMikoDerm a 10-fold continued its application which  led to an increase in serum concentrations of urea and creatinine,increasing  the mass index can serve as a marker of renal decline functional condition of the body.

Introduction. Historically, pesticides are evaluated more strictly from a medical point of view than other chemicals. Since their features, such as deliberate introduction into the environment, the possibility of contact with them by large masses of the population, and the high biological activity determine their potential danger to humans. Purpose of research - study of the biological effect of a technical product derived from triazoles when it is repeatedly ingested orally in mammals (rats), establishment of inactive and active doses, justification of the permissible daily dose (DSD) for humans. Material and methods. In acute experiments, white rats were used, including 6 animals in the group. Tested dose: 500-4000 mg/kg of body weight. A chronic (12 months) experiment was performed on 80 male rats with a bodyweight of 180-190 g at the beginning of the study. Tested doses: 5.0; 16.0 and 55.0 mg/kg of body weight (1 control and 3 experimental animals, 20 individuals each). In the dynamics of the experiment, we observed the condition and behavior of animals, water, and food consumption, recorded the timing of death, changes in body weight, physiological, biochemical, and hematological indices. Results. Indices of the acute oral toxicity on the studied product LD50 male rats were 2250 ± 483 mg/kg body weight. The dose of 5.0 mg / kg of body weight was not found to cause significant changes in all studied indices. The doses of 16.0 and 55.0 mg/kg of body weight had a polytropic effect on the body in experimental animals. Discussion. The studied product for the acute oral toxicity refers to low-hazard compounds, the doses of 16.0 and 55.0 mg/kg of body weight has a polytropic effect on the mammalian body, causing changes in carbohydrate, lipid, and lipoprotein metabolism in the body of rats - was accepted as acting. The dose of 5.0 mg / kg of body weight, when administered in rats, there are no changes in all the studied parameters throughout the experiment, is accepted as invalid. Based on the inactive dose-5.0 mg/kg of body weight and taking into account the reserve factor of 100, we have scientifically justified DSD for a person at the level of 0.05 mg/kg. Summary. The conducted sanitary and Toxicological studies indicate the need to assess the toxicity of new technical products to the mammalian body, to increase the reliability of the developed hygiene standards in environmental objects and food products.

INTERNAL ORGANS CHAR ACTERISTICS OF NATIVE CHICKEN FED BY COCONUT OIL (Cocos nucifera) ON DIET. The research was carried to determine the internal organs characteristics of buras chickens fed coconut (Cocos mucifera) oil in diet. A total 100 unsexed buras chickens was used in this experiment. The design used in this study was a completely randomized design (CRD) consisting of 5 treatments and 5 replications (4 hens each). The data were subjected to analysis of variance, when the treatments indicated significant effect it was continued Duncan’s Multiple Range Test. Five dietary treatments containing 0, 0.5%, 1 %, 1,5%, and 2% levels of coconut oil (CO) with five replicates were applied to chickens.  Parameters measured were body weight, heart, liver, pancreas  and gizzard weight. Result showed that CO in the ration significantly increased the body weight (P<0.01) but did not affect to heart weight, liver weight, pancreas weight and gizzard weight.(P>0.05) It can be concluded that coconut oil in the diet can’t increase the internal organ characteristics. We can gave the 2% CO in the diet for the best results. Key words: Internal Organs, Coconut Oil, Buras Chickens

Native breeds of ducks have been the subject of many studies in the past, yet the relevant knowledge is still incomplete and needs to be further expanded. The objective of this study was to provide information about differences in growth performance, dressing percentage, carcass composition and digestive morphometry among three lines of Pekin ducks from conservation flocks raised in Poland. The study used 180 sexed Pekin ducks—30 males and 30 females of line P33 (ducks of Polish origin), 30 males and 30 females of line P8 (ducks of Danish origin), and 30 males and 30 females of line P9 (ducks of French origin). Throughout the study (49 d), ducks were confined indoors in six pens. Birds were fed complete commercial diets ad libitum and had unrestricted access to water. The compared lines of ducks differed significantly in body weight from 1 to 49 d of age except of ducks of both sexes at 14 d. At 49 d of age, significant differences were observed between the tested ducks in all the body measurements. Duck genotype had a significant effect on preslaughter body weight, carcass weight and breast muscle, neck and remainders contents, caeca length, liver weight and gizzard percentage. The results show that the tested ducks were significantly different and unique, mainly in terms of the body biometric characteristics.

1. The ability of alcoholic-precipitated extracts of beef tissue—brain, spleen, heart, and kidney—to stimulate the growth of Staphylococcus aureus, in vitro, and to convert the yellow S form to a white R variant with altered biochemical characteristics conforming to those of an avirulent organism, has been confirmed. 2. The avirulence of the white R variant has been established by tests in vivo on mice. 3. Staphylococcus aureus infections induced subcutaneously, intraperitoneally, and intravenously in mice responded favorably to brain extract following subcutaneous or oral administration. The mortality was 2 per cent in 444 experimental animals and 81 per cent in 448 control animals. 4. The extracts appeared equally efficient when used therapeutically (mortality 2 per cent of 162 experimental animals and 90 per cent in the control series) or prophylactically (mortality 2 per cent of 282 experimental animals and 76 per cent in 286 control mice). Extracts of brain and spleen were more effective than those of either heart or kidney. 5. Studies concerning the mechanism of action of the tissue extracts indicate that they prevented the formation of toxin by Staphylococcus aureus, and had but little effect on toxin actions. 6. Toxicity tests revealed that the brain and spleen extracts were relatively non-toxic, dosages equivalent to 2 per cent of the body weight being well tolerated. Kidney and heart extracts were much more toxic, producing mortality in dosages as low as 0.3 per cent of the body weight.

Clathrochelate Complexes

We studied the chronic toxicity of the compounds of Iron(iv). We monitored the dynamics of the body weight, relative weight coefficients of the internal organs, the content of the hemoglobin, the morphological parameters of blood, and biochemical parameters of serum of blood of quails after use of Iron(IV) clathrochelate complexes at the doses 1/10 and 1/5 DL50 them for 30 days. Daily drinking of quails of experimental groups of solution of Iron(IV) clathrochelate complexes3 at the doses 76.43 and 152.86 mg/kg of body weight caused the reduction of body weight by 3 and 5% respectively on the thirtieth day. A tendency to increase the relative weight of the kidneys and to decrease the relative weight of the liver, heart and spleen showed an excessive load of Iron(IV) clathrochelate complexes on the internal organs of quails. Hemoglobin in the blood of the quails of the experimental groups was less by 2-34% (P 0.05) than the control indicator but the indicator of the number of erythrocytes in the quails of the control and experimental groups for 30 days was within the physiological values. The use of Iron(IV) clathrochelate complexes caused the development of hypoproteinemia, hypoalbuminemia, and short-term hypoglycemia in the serum of the blood of the quails of the experimental groups. Changes in an activity of alanine aminotransferase and aspartate aminotransferase for 30 days were not expressed, but the activity of alkaline phosphatase was significantly higher compared to the control indicators during the experimental period. Drinking the solution of Iron(IV) clathrochelate complexes caused hypercreatinemia and hyperuricemia, which indicates a decrease in the filtration capacity of the kidney glomeruli. We have seen an increase in the levels total Calcium and inorganic Phosphorus.

Assessment of toxicities of DA.AMLODEPON HVD hard capsule on experimental animals. The acute toxicity of DA.AMLODEPON HVD was assessed on Swiss mice according to World Health Organization Guidance, and LD50 determination according to the method of Litchfield – Wilcoxon. The sub-chronic toxicity study of DA.AMLODEPON HVD at two doses (0.42 g/kg/day and 1.26g/kg/day) was conducted in rats for four consecutive weeks. After administration, general conditions and the body weight of rats were evaluated. Blood samples were collected for analyzing serum parameters before treatment (T0), second week (T1), and fourth week (T2). Histopathological analysis of livers and kidneys was observed at the end of the experiment. The results revealed that mice were taken up to a maximum dose of 39.15 g/kg with no symptoms of acute toxicity, LD50 of DA.AMLODEPON HVD has not been determined. The sub-chronic toxicity study at two doses did not change the body weight of rats, general conditions. The parameters for structures and functions of livers and kidneys and microscopic of the livers and kidneys are in a normal range during the study period.

The weight of internal organs (swimbladder, kidney, liver, spleen) in relation to the body weight was studied in common carp fingerlings divided into three groups on the basis of swimbladder appearance and microscopic examination of the kidney. The fish had been collected from different Hungarian fish farms at the time when swimbladder inflammation (SBI) usually occurs (in July and August). The first group comprised fish with severe signs of SBI and massive renal sphaerosporosis, the second group consisted of fish with milder swimbladder changes and/or kidney infection by a low number of Sphaerospora renicola, while the third group was constituted by infection-free common carp fry. Statistical analysis of swimbladder, kidney, liver and spleen weight in relation to the body weight revealed that in the infected groups the internal organs were substantially enlarged. This suggests that in common carp fry with SBI the swimbladder changes are accompanied by reno-, hepato- and splenomegaly.

Trait Locus

A network of four interacting loci has been reported previously to influence growth in two lines of chickens divergently selected for body weight at 56 days of age. Located on chromosomes 3 ( Growth4), 4 ( Growth6), 7 ( Growth9), and 20 ( Growth12), they explained nearly half of the difference in body weight at selection age between the two lines. The original study reported effects on body weight and fat deposition, but no attempts were made to explore the effects of the network on other phenotypes measured in the F2 population. In this study we conducted further analyses to evaluate the specific effects of the four-locus network on other metabolic traits as well as refining results from the original study by including a larger number of genetic markers in the quantitative trait locus (QTL) regions. We confirm the previously described effect of the epistatic network on body weight and show that the network increases the total amount of muscle and fat as well as the weight of the internal organs. The network as a whole did not change the relative content of any studied organs or tissues in the body. There was, however, a significant interaction between the loci on chromosomes 3 and 7 that changed the relative proportion of abdominal fat and breast muscle in the chicken by increasing abdominal fat weight without a corresponding increase in muscle mass.
