It is determined the relevance of the study of ordinary apricot from the Central Asian group in order to obtain dried fruit in the forest-steppe zone of Ukraine. The kinds and forms of the Central Asian group bear smaller, but high-sugar fruit. It is important to notice nowadays markets and supermarkets offer dried apricots imported from Kyrgyzstan, Azerbaijan, Uzbekistan, Georgia, Turkey, Iran and other countries. The process of introduction of subtropical fruit crops P. armeniaca.was started in Khorol botanical garden. There is the sort P. armeniaca, belonging to the Central Asian group (September dried apricot) grown in Uzbekistan. The height of the experimental tree is above seven meters, its crown consists of four skeleton branches, its trunk diameter is fourteen meters. In 2021 it was in blossom at the beginning of May. This sort grown in the forest-steppe zone of Ukraine is characterized by bearing regular fruits. It is being planning to study the biochemical content of the fruits, their sugar content and dry content and producing dried fruits. In 2020 it was taken the sample of Kyrgyz apricot for science experiment of introduction P. armeniaca. Its fruits are fleshy. During drying they are practically stored as whole fruits. This apricot sort grown in Kyrgyzstan is characterized by dehydration and drying in the trees. It gives an opportunity to get dried apricots by natural way.

Histological analysis of the wall of the excretory ducts was performed in order to identify common and distinctive features of the structural and spatial organization of the excretory ducts of the human lacrimal gland. In the system of excretory ducts of the human lacrimal gland revealed changes in diameter, which are visualized in sections in the form of local narrowings and pear-shaped extensions (the phenomenon of siphonization). In addition to the siphon-like structure of some excretory ducts, the phenomenon of its spiraling is noted. At the same time the tendency to existence of the greatest throughput for secretion in interparticle and general output channels is noted.The obtained morphological data will help to elucidate the mechanism of secretion outflow from the bifurcated system of the excretory ducts of the human lacrimal gland.

The research results on the effect of water flowage of different current speed on the mollusks contamination have been presented in the paper. There is limited data in literature as to the effect of current speed on mollusks contamination under contemporary conditions of Ukrainian Polissya. The presented information broadens and complements the data. The current speed proved to indirectly affect the level of mollusks contamination by larvae stage of trematodes. It was stated that in streamflows with oligotype (0 – 0,1m/s) and mesotype (0,1 – 1m/s) current speeds the infection extensity of some mollusks species by parthenita and trematodes larvae may vary in wide range. It should be noted, that there were no rivers of polytype current speed in the studied waterbody. The high infection extensity indices by parthenita and trematodes larvae were revealed in Bithynia tentaculata mollusks (Linnaeus, 1758), Viviparus (Viviparus) viviparus (Linnaeus, 1758) in the Uzh, the Revna, the Seim under oligotype and mesotype current speed. This testifies to the fact, that contamination of the above mollusks types does not essentially depend on the current speed. We consider it is caused by high density of their population and the number of definite hosts. The above mentioned mollusks are the bridging hosts of trematodes which complete their development mainly in birds and fishes. The current speed is determinative as to contamination of widely distributed mollusks species as Lymnaea stagnalis (Linnaeus, 1758) and Planorbarius corneus (Linnaeus, 1758) which are stagnophiles. The comparison of infection extensity of joint river mollusks selection with oligotype and mesotype current speeds has been conducted.

Article are presents the results of features of gametogenesis and its seasonal dynamics in Esperiana esperi (Ferussac, 1823). In Ukraine, these rheophilic mollusks are common in the coastal stretches of large rivers that form part of the hydroelectric network of its Right Bank. The populations of these animals belong to the category of polycyclic, that is, consisting of individuals of several generations, with a maximum life expectancy of about two years. The study found that gametogenesis in E. esperi is a synchronous process that occurs under the same environmental conditions during spermatogenesis and ovogenesis. Examination of the histological sections of the sex glands of these mollusks revealed that it is a stage process that involves five stages of maturity of the gonads: the beginning of gametogenesis, active gametogenesis, pre-spawning, spawning and post-spawning stages, which are characteristic for certain seasons of the year. According to the analysis, there is a direct correlation between the stages of gametogenesis and the temperature conditions of the environment. Accordingly, gametogenesis in southern mollusk populations has been found to occur earlier than northern populations. The number of mature oocytes determines the time of occurrence of fertility peaks, which occur mainly in July for northern populations and for June for the same southern populations of molluscs, indicating a different temperature optimum. According to the latter, the highest levels of stability are characterized by southern populations of the species studied. Generalized information on the number of oocytes also characterizes the duration of periods of E. esperi life cycles from the northern and southern territories of the habitat in Ukraine under current climatic conditions. These molluscs are found to have the longest reproduction period, which lasts about a year. Reproduction takes only 3.5 months, and post-reproduction takes 1-3 (as an extreme rarity - up to 7 months in northern populations).

The article presents the results of the study of taxonomic and trophic structure, as well as features of seasonal dynamics of heterotrophic flagellates of the Uzh River (Korosten). In the investigated reservoir, 21 species of heterotrophic flagellates were identified, among which 7 species belong to the Excavata supergroup, 9 to the SAR (systematic group including Stramenopiles, Alveolata and Rhizaria) and 5 species of uncertain systematic position. According to the nutrition strategy, 76% of the species found are actively searching for food and 24% are catching or intercepting a food particle with flagella, absorbing it directly on the cell surface; the main trophic group are bacteriodetritophages-collectors, they amount 62%, at 14% are bacteriodetritophages-filterers and euryphages; and 10% (2 species) are predators – Allantion tachyploon and Phyllomitus apiculatus. Peaks of heterotrophic flagellates were recorded in June – 9 species and in October – 7 species, at the highest number in June – 5410 copies/ml and in April – 5062 copies/ml. The lowest species wealth was observed in January – 2 species, at the lowest number in January – 116 copies/ml and in December – 174 copies/ml. It has been established that eudominant species were absent in June and August due to the dominance of other flagellates. Most often, in January, February, May, July and December, this was Bodo designis. Goniomonas truncata and Spumella vivipara are slightly inferior. A. saltans, Rhynchomonas nasuta and Paraphysomonas vestita were eudominants in only one month. Almost the same trend persists among dominant species, most often B. designis and G. truncate. The predominant subdominants are represented by S. major, Heteromita minima and Protaspis gemmifera, moreover S. major, P. geminifera, P. apiculatus, A. tachyploon, Anthophysa vegetans and Protaspis simplex occur only in this flagellate group.

THE INFLUENCE OF DETERGENTS ON THE CILIA LOCOMOTION ACTIVITY OF EPITHELIUM IN SINANODONTA WOODIANA (MOLLUSCA, UNIONIDAE) The influence of one of the most popular detergent «Ushasty nian» («Vinnitsapobutkhim», Ukraine) in concentrations of 3, 6, 12, 24, and 48 mg/dm3 on the duration and beat frequency of the glimmeral epithelium cilia of the gill apparatus of male, female and hermaphrodite Sinanodonta woodiana (Lea, 1834) specimens was investigated. The damaging effect on the viability of these mol-lusks, including the locomotive activity of the frontal cilia of their gill glimmeral epithelium depends on the toxic factor levels. In the toxicological study, the pathological process in mollusks shortly de-veloped in consequent five stages in two days. At 3 and 6 mg/dm3 concentrations of detergent, the signs observed in all three categories of molluscs included in vitro increased duration of locomotion and beat frequency of the glimmeral epithelium cilia. That state of experimental molluscs corresponds with the stimulation stage of pathological process induced by toxicological poisoning. Aforemen-tioned changes are the signs of adaptive protection process aimed to counteract the damage inflicted by the toxic substance. At 12 and 24 mg/dm3 of detergent, the molluscs quickly entered the depres-sion stage of the pathological process. It manifests as a statistically significant sharp decrease of du-ration of activity and beat frequency of glimmeral epithelium cilia. At 24 mg/dm3 of toxicant, towards the end of exposure that stage was superseded by the sublethal stage. The latter is charac-terized by complete destruction of respiratory epithelium, maximum oedema of body tissues (espe-cially in the foot), loss of locomotion, and almost total loss of tactile sensitivity. At 48 mg/dm3 of toxicant, the sequence of depression, sublethal and lethal stages is realized quickly.
