Effect of Mucuna pruriens and Millettia pinnata (Fabaceae) minerals on some isolated organs of envenomated and treated Oryctolagus cuniculus

The general objective of this study was to evaluate the antivenom effect of minerals from two plants on some vital organs (heart, liver, kidneys and lungs) of rabbits. It was carried out with 36 rabbits (19 males and 17 females) divided into portions E1, E2 and E3. E1 consisted of 2 control lots (3 males and 3 females), and 1 experimental lot (2 males and 1 female). E2 comprised 7 batches of rabbits (2 males and 1 female). E3 consisted of 2 batches of 3 females. Naja nigricollis venom was injected for approximately 20-30 minutes to the animals in the experimental batch of E1, and to those in E2 and E3. Then, E2 and E3 were treated preventively and curatively with minerals, respectively. After the determination of their biochemical and hematological parameters, they were necropsied separately and then their organs were removed, weighed and their appearance was studied. The study revealed that the venom of Naja nigricollis was the cause of death of all the animals of the experimental batch of E1. On the other hand, the use of P2 and P3 as a preventive measure was able to save 1 out of 3 and 3 individuals respectively from the venom. As for P3 as a curative measure, it kept alive 2 out of 3 individuals against the venom. Thus, for the development of anti-venomous phytomedicine, it would be advisable to use the minerals from P3 (ash of Millettia pinnata).

Streptomyces biomass – effective additive in poultry nutrition

Introduction. The breeding of domestic poultry is an important source to soupplement the human needs in animal proteins with a high biological value. Therefore, knowledge and guidance of the factors that influence poultry production is a guarantee of increasing these productions, both in terms of quantity and quality.Material and methods. The investigation was aimed to administer the 0.05% and 0.1% streptomyces biomass in the recipe of combined fodder, intended for the feeding of young poultry of the Argintie de Adler breed, in order to identify the effectiveness of its administration.Results. The supplementing of streptomyces biomass in the proportion of 0.1% in the recipe of combined feed intended for feeding the poultry of the Argintie de Adler breed, contributed to a 5.1% gross weight gain and a lower specific consumption by 9.9% in chickens from the experimental batch, compared to those of the control batch.Conclusions. The assessment of the dynamic indices of growth and development in chickens of the Argintie de Adler breed, as a result of supplementation of nutrition recipes with streptomyces biomass, has established a sure way to boost the productivity.

Evaluation of the hemogram of Oryctolagus cuniculus envenomus

The overall objective of this study was to evaluate the hemolysing action of Naja nigricollis venom on rabbit blood. To carry out this study, three batches of three rabbits were formed with two control batches and one experimental batch. Each control lot is composed of three rabbits (males or females) while the experimental lot is composed of two males and one female. Each rabbit from the control lots was separately collected in the purple tube (EDTA) and transported to the laboratory for analysis. The rabbits from the experimental batch were also collected distinctly a few minutes after the injection of the venom of Naja nigricollis for the analysis of haematological parameters. However, before the analysis of the hematological parameters of the rabbits from the control and experimental batches, an in vitro hemolysis test of Naja nigricollis venom was performed to verify its hemolysing power. The results showed that Naja nigricollis venom has a dose-dependent in vitro hemolysing power. As for the haemogram, it revealed that the venom of Naja nigricollis has a decreasing effect on blood cells (red and white blood cells), on haemoglobin and on haematocrit, and an elevation on MGVs thus promoting anaemia.

Recycling of waste oils with different composition using flexible type technology

Present issue proposes a solution to the problem of the waste oils with different composition recycling into esters of fatty acids and low-molecular alcohols by using flexible type technology. Waste oils differ in the composition of hydrocarbon radicals of the vegetable oils triglycerides and in the content of the free fatty acids impurities. For waste oils processing it is advisable to use technology options that differ in combinations of basic technological operations. An algorithm is proposed for selecting the main technological operations and their combinations for inclusion in the technology process, taking into account the composition of the recycling raw materials and the type of product obtained. The flexibility of the technology is provided by using different combinations of reactor blocks, each of which is designed to perform one of the provided technological operations. The developed flexible type technology was tested in the recycling of experimental batch of the low-eruption rapeseed oil waste.

Justification of express technology in the «Pasta Filata» group cheese production

The most common one of the «Pasta Filata» group is «Mozzarella», a soft Italian cheese that is now made from cow's milk and widely used in many dishes, especially as a pizza topping, which is the most popular food for young people. The paper substantiates the express technology for the production of soft cheese like «Mozzarella». The first batch of Mozzarella-type soft cheese was made using traditionally accepted technology. Another batch of cheese samples was made using express technology. In contrast to traditional technology, an aqueous solution of citric acid was added to the normalized mixture before making the main components, thereby instantly increasing the active acidity, which reduced the duration of the cheddarization process of the cheese mass. Other technological operations were similar to traditional technology. The research results show that during the production of experimental batches of cheese at the stage of cheese curd formation, the milk coagulation process in the samples obtained by traditional technology took an average of 42,3 min ± 1,45 min, whereas in the samples of experimental batch № 2, this process was much faster, only 15,7 min ± 2,40 min by adding an aqueous citric acid solution. The research results have established that the production of the soft cheese type «Mozzarella» by express technology leads to the reduction of the technological process, namely to decrease (by 9 times) the duration of cheddarization of the cheese mass which produces the necessary consistency (pH 5,3-5,2) for the further melting and stretching the cheese dough. The output of the finished product under the various technologies of production of soft «Mozzarella» cheese was almost at the same level. Thus, the weight of cheese of experimental batch № 1 on average was 829 g ± 12,66, respectively, the mass of cheese of batch № 2 - 847 g ± 14,36. The tasting assessment on a point scale showed that all tested cheese lots, regardless of the production technology had rather high points (41.8-42.0) and had perfect organoleptic characteristics that are typical for the type of cheese understudy and meets the standard requirements. In general, the analysis of these studies showed that the production of soft cheese, such as «Mozzarella» by the express technology, namely the use of citric acid leads to a minimal time of the cheddarization process. Reduces the clotting time of milk and the formation of the cheese mass of the necessary consistency for further melting and extraction, which in turn causes the technological process of production of the finished product to be reduced altogether.

Evaluation of the Effect of Red Onion Extract Consumption in Mice (Mus musculus)

Red onion (Allium cepa) is commonly used in human diet, representing an important source of flavonoids, with argued therapeutic values in humans. In animals, the tolerance to onion varies according to species and the quantity intake, carnivores being the most sensitive. The experiment aims to identify the negative potential effects in mice after the aqueous red onion extract consumption over 56 days. Similar to some long-term studies performed on other species using aqueous or alcoholic red onion extracts, for the mice of the experimental batch were registered the hepatic and renal disturbances, paraclinically and microscopically registered, which might limit the testing of the effects of the extracts from red onion on mice.

Modern refractories for quick change of beaker glasses produced by GIR-ENGINEERING

The regularities of the development of the defect of a metal jet like «fan» in the course of casting on a CCM are considered. The results of studies on the nature of nonmetallic inclusions, which are deposited on the internal cavity of the gauge insert of the beaker glass, are presented. Taking into account the identified patterns and key factors for the development of a violation of the compactness of the metal jet, an experimental batch of beaker glasses of the CNC and MNC systems was tested, which allowed to achieve a stable casting process.
