The study of acute cutaneous toxicity and local irritant effect of the drugs Insacar Total C Plus and Insacar Total K Plus on mongrel white rats was conducted in doses of 5000 and 10 000 mg/kg of body weight (BW). When the drugs were applied to the skin of rats, no animal deaths were recorded during the entire observation period. Thus, the LD50 is more than 10 000 mg / kg of BW. A single application of the drugs to the skin in rats at a dose of 1 ml/100 g (10 000 units) in two experimental groups on the 7th and 9th day of the study showed the most pronounced irritant effect. In this regard, the drugs have an irritating effect – 1 point. The studied drugs Insacar Total C Plus and Insacar Total K Plus belong to the group of insectoacaricidal and anthelmintic agents. The substances included in its composition have a contact and systemic effect on ectoparasites and nematodes. They are complex medicines containing 4 active components – moxidectin, pyriproxifen, imidacloprid, praziquantel. Such a combination of active substances is characterized by effectiveness against a larger number of parasite species, stages of their development, and in addition, reduce the likelihood of developing resistance of pathogens to drugs.

This paper is about studying the rootstocks for stone fruit breeds (sweet cherry) in condition of Hissar valley in Tajikistan. Each type of rootstock has its own biological characteristics and imposes specific requirements for growing and development, both during reproduction in the mother plantation and during the growth of trees. For example, the root system in sour cherry is more superficial that of wild sweet cherry. Therefore, the care of trees grafted on sour cherry and wild cherry and of mother plantation bushes of these rootstocks cannot be same. Besides, there are very significant differences among the individual groups of rootstocks. Wild cherry, Mahaleb cherry and Lubskaya cherry are used as rootstocks in the conditions of the Hissar Valley in Tajikistan. High specificity of sweet cherry cultivar varieties depends on the rootstocks. Phenological observation were carried out in our experiments during years 2013-2018 in order to study their winter resistance, yield capacity and fruit quality. The same care for root and grafted plants was carried out during the entire observation period. At the same time a certain ratio between the leaf system of the rootstock and the graft was maintained by trimming the crown. As a result of the evolution and selection, we have identified the wild cherry forms which are distinguished by the highest yields. The most valuable cultivar varieties are Napoleon cherry and Bagration cherry. Compotes made of these varieties have received high evaluation in tasting.

Abstract. We exploit a catalogue of 1466 rainfall events with landslides in the 90 year period 1921–2010 to study temporal and geographical variations in the occurrence of landslides in Calabria, Southern Italy. We use daily rainfall records obtained by a network of 318 rain gauges to reconstruct 448 493 rainfall events. Combining the rainfall and the landslide information, we obtain a catalogue of 1466 rainfall events with landslides (REL) in Calabria from 1921 to 2010, where a REL is the occurrence of one or more landslide during or immediately after a rainfall event. We find that the geographical and the temporal distributions of the rainfall-induced landslides have changed in the observation period. The average and the maximum values of the cumulated event rainfall that have resulted in landslides in the recent-most 30 year period 1981–2010 are lower than the values necessary to trigger landslides in previous periods, whereas the duration of the rainfall events that triggered landslides has remained the same. This can be considered evidence of variations in rainfall conditions, but also an increase in the vulnerability of the territory. We further find that the yearly distribution of rainfall-induced landslides has changed in the observation period, analysing the variations in the number of rainfall events with landslides occurred in each month in three 30 year periods. To investigate variations in the impact of REL on the population, we compared the number of REL in each of the 409 municipalities in Calabria, with the size of the population in the municipalities, measured by national Censuses conducted in 1951, 1981, and 2011. For the purpose, we adopted two strategies. The first strategy considered impact as IREL = #REL/P and the second strategy measured impact as RREL = #REL × P, where #REL is the total number of REL in a period, and P is the size of the population in the same period and geographical area. Considering the entire observation period, IREL and RREL have both increased in Calabria. However, considering the changes between the recent period 1981–2010 and the previous period 1951–1980, results are more variegated with a number of municipalities where IREL and RREL have increased, or decreased. Municipalities where IREL has increased are mainly in the mountains, and municipalities where RREL has increased are mainly along the coasts.

The aim is to establish the features of morphological and morphometric changes in the skin of guinea pigs in erythemal, early post-erythemal and late post-erythemic periods after local ultraviolet irradiation. Materials and methods: Studies were conducted on 54 albino guinea pigs weighing 400-500 g. Ultraviolet erythema was caused by irradiation in 1 minimum erythemal dose. The control group included intact guinea pigs. After 2, 4 hours, on the 3rd, 8th, 15th, 21st, 28th day, the fragments of the irradiated skin were investigated using histochemical and morphometric methods. Results: After 2, 4 hours after irradiation, dyscirculatory changes in the skin develop. By the 3rd day of the experiment a morphological picture of acute inflammation in the epidermis and dermis develops, apoptotic keratinocytes appear (sunburn cells), which is accompanied by thickening of the epidermis and an increase in the density of fibroblasts. By the 8th day proliferative-hyperplastic and degenerative changes begin to prevail, including dystrophic nature, the thickness of the epidermis and the density of fibroblasts reach a maximum. In the long term, on the 15-28th day, dystrophic changes of the epidermis, dyskeratosis, changes in the number and structure of elastic fibers with an increase in uneven fibrosis, collagenization processes and the development of sclerotic changes, as well as a significant thickening of the epidermis, an increase in the density of fibroblasts are observed. Conclusions: The data obtained indicate pronounced morphofunctional changes in the skin in the zone of local ultraviolet irradiation observed throughout the entire observation period.

Luohuazizhu suppository is a Traditional Chinese Medicine used in clinic to treat cervicitis, which is prepared from Callicarpa nudiflora Hook. et Arn (C. nudiflora), an herbal Chinese medicine named Luohuazizhu. This study aimed to figure out the active constituents of C. nudiflora and the potential mechanism for its anti-cervicitis effect. The ethanol extract in C. nudiflora (CNE) and the different fractions of CNE extracted by petroleum ether (CNE-p), dichloromethane (CNE-d), and n-butanol (CNE-b) were tested in vivo for their anti-cervicitis effects. Then the isolated compounds from the CNE-p were tested in vitro for their anti-inflammatory activities. The results displayed that CNE-p, CNE-d, and CNE-b exhibited adequate anti-cervicitis effects, with CNE-p showing the highest efficacy. Further experiment demonstrated that CNE-p could significantly inhibit the expression of NLRP3 in vitro. Six diterpenoids obtained from the CNE-p showed the ability to regulate inflammatory factor levels in vitro. Among these compounds, compounds 1 (callicarpic acid A) and 2 (syn-3,4-seco-12S-hydroxy-15,16-epoxy-4(18),8(17),3(16),14(15)-labdatetraen-3-oic acid) were the most effective agents, and they also inhibited the expression level of NLRP3 in vitro. The results confirmed that C. nudiflora has significant anti-cervicitis effects and the diterpenoids were most likely to be its active components. These data provide scientific support for the clinic usage of Luohuazizhu suppository and the development of new agents in treating cervicitis.

Objective of the study. prove the effectiveness of brief psychological intervention (BPI) conducted by an internist in achieving and maintaining abstinence in patients with alcoholic liver disease (ALD).Materials and methods. A total of 65 patients were included in the study: 29 patients in the BPI group and 36 in the historical control group. A comparative analysis of the frequency of achievement and maintenance of abstinence and analysis of factors associated with these parameters were conducted.Results of the study. The frequency of achieving abstinence was significantly higher in the BPI group compared with the control group after 6, 9, 12 and 24 months from the date of inclusion in the study (p <0.001, p = 0.002, p = 0.001, p = 0.017, respectively; criterion χ2). The frequency of failures to achieve abstinence in the CPC group was significantly lower than in the control group after 6 months and in general for the entire observation period (p = 0.004, p = 0.005, respectively; criterion χ2). Provision of BPIs for 12 months after alcohol-induced decompensation serves as a factor that is reliably associated with achieving total abstinence within 24 months (p = 0.001, criterion χ2). Decompensated cirrhosis of the liver serves as factors independently associated with failures to achieve abstinence within 24 months after alcohol-induced illness (OS: 10.72 [95% CI 2.17–52.81]; p = 0.004) and the absence of BPI after discharge from the hospital (OSH BPI: 0.80 [95% CI 0.14–0.479]; p = 0.006)Conclusion. BPIs provided by an internist to the patients with ABD for 12 months after alcohol-induced decompensation leads to a higher rate of achieving total abstinence and decrease in the frequency of failures to achieve abstinence within 24 months after discharge from the hospital.
