The article provides brief information about cardiotonic, sedative, cytostatic, diuretic, and antibacterial effects of biologically active compounds of Adonis L. (Ranunculaceae) species. Chemical studies allowed to identify the cardiac glycosides, or cardenolides: or cardenolides: adontoxin, adonitol, adonitoxigenin, acetyldigitoxin and others. In scientific medicine, it is currently allowed to use Adonis vernalis L. Other types of Adonis have a similar chemical composition and are offered as substitutes for this official species, for example, Adonis apennina L. Many Adonis species have limited natural resources, and in some regions are rare, requiring conservation of their natural populations. The search for alternative sources of medicinal plant raw materials, based on this, is relevant. The experimental part of our research was carried out using the morphological and geographical method with the involvement of information on ecology and phenology. For the first time summarizes the diagnostic features of Adonis flora of Russian flora. Previously unknown structural features (shape and size of anthers) were identified that characterize the subgenera Adonanthe and Adonis. Taxonomic study of the genus Adonis of the Russian flora allowed us to determine its species composition, clarify its systematic affiliation, and nomenclature synonyms. 9 species were identified. Of these, 6 are perennials belonging to the subgenus Adonanthe, section Consiligo, which includes 2 subsections: Amurenses (2 species) and Vernales, which is differentiated into 2 rows: Apenninae (2 species) and Vernales (2 species). Subgenus Adonis is represented by 2 sections: Adonis (1 species) and Lophocarpa with sections Aestivales (1 species) and Dentatae (1 species). For all the considered species and varieties, the main distribution areas are given. A key has been compiled to determine the wild Adonis species distributed in Russia.

For millennia, humans have used hundreds of medicinal plants to treat diseases. Currently, many species with important characteristics are known to alleviate a wide range of health problems, mainly in rural areas, where the use of these resources is very high, even replacing scientific medicine almost completely. This paper presents the dehydration of medicinal plants that are grown in the State of Campeche through direct and indirect solar technologies in order to evaluate the influence of air flow and temperature on the color of the final product through the L* a* scale. b*, analyzing the activity of water and humidity during the drying process. The experimental results showed that the direct solar dryer with forced convection presents a little significant color change in a drying time of 400 min on average, guaranteeing the null bacterial proliferation and reaching a final humidity between 9 % and 11 %.

Throughout tropical urban Latin America, yellow fever wreaked havoc. Located at sea level, Guayaquil (Ecuador) and Puerto Barrios (Guatemala) were particularly susceptible to yellow fever; yet, Ecuadorians and Guatemalans enjoyed significant success in early twentieth-century campaigns against yellow fever. Reflecting international efforts that informed, collaborated with, and at times underwrote Latin American public health campaigns, the Rockefeller Foundation (RF) sent representatives to Guatemala and Ecuador in the mid-1910s to eradicate yellow fever. While those interventions enjoyed immediate success, the long-term effects were more ambiguous. By collaborating with RF, Ecuador had all but eradicated yellow fever by 1919. In Guatemala, however, a few months after RF declared Guatemala free of yellow fever, influenza struck, likely originating from US military camps in Guatemala that RF sought to shield from yellow fever.  Analysis of early twentieth-century yellow fever epidemics and campaigns to arrest them sheds light on COVID-19 pandemic challenges. Even as knowledge of disease etiology was evolving in Ecuador and Guatemala, most leaders accepted or at least did not publicly reject scientific medicine. In contrast, beginning with the most powerful politicians and filtering down throughout federal, state, and municipal authorities, many US leaders rejected science crucial to the campaigns against COVID-19. Similarly, in a pattern that resonates with US residents rejecting precautionary measures against COVID-19 such as wearing masks and maintaining social distance, compliance with anti-yellow fever campaigns was not always forthcoming.

WHILE MEDICAL HISTORIANS cannot provide us with accurate statistics concerning the incidence of rickets and scurvy in centuries past, they leave little room for doubt about the high prevalence of these disorders prior to the advent of modern scientific medicine. Thus, Castiglione has written that in the sixteenth century scurvy raged throughout northern Europe, in Scandinavia, on the shores of the Baltic, and in the interior of Germany. It is interesting to note, however, that Jacques Cartier, whose sailors had been ravaged by scurvy, learned in 1536 from the Indians that the malady could be cured by juices of the almeda tree. This was 200 years before James Lind demonstrated the curative effects of lemon juice in his treatise on scurvy published in 1753 and almost 400 years before ascorbic acid, which was isolated by Szent-Gyorgi in 1928, was recognized to be vitamin C by Waugh and King in 1932. Rickets, likewise, was occurring in a large portion of children prior to the discovery of the existence of vitamin D by Hess, Steinbock, and Windaus in 1918, of its therapeutic value by Mellanby in 1919, of the equivalent role of sunlight by Hess in 1921, and of the chemical composition of the vitamins by Windaus in 1922. But 200 years earlier Friedrick Hoffman had the answer to the control of this disease almost in hand. He attached much importance to climatic conditions as a factor in rickets, noting that if anything is specially powerful in producing this affliction, it is a surrounding atmosphere of cold foggy air. He cited as striking evidence of this the famous emporium of England, London, which he found to be specially apt to produce and foster this disease.

Transplacental Transfer

1. Camphor has no established, therapeutic role in scientific medicine. 2. Camphor has potent, serious toxicologic actions; the ingestion of relatively small amounts has proven fatal. 3. Although accidental oral ingestion is the most common route of intoxication, significant quantities can be absorbed percutaneously and via inhalation. 4. Transplacental transfer may be toxic to the fetus. 5. Camphorated oil, in particular, is the worst offender in accidental ingestions, because it is mistaken for a variety of over-the-counter products and is also accidentally ingested by toddlers. 6. As long as camphor-containing products continue to be marketed, pediatricians should warn parents of the dangers of camphor-containing products in the home, especially camphorated oil.

The publication last year of Professor M. M. Nevyadomsky's Mechanics will certainly awaken interest in the name of Professor Zakhar'in. If, as D. D. Pletnev put it, we do not know Russian scientific medicine (Pletnev, Russian therapeutic schools), yet such representatives of it as Zakharyin, Botkin, Ostroumov, L. Popov, Volkov, Obraztsov, Shatilov, etc., can be called classics of Russian clinical medicine. In recent years, we have seen in Russian medical literature a number of works profound in content and original in their very title, such as, for example, "Introduction to Thanatology. In recent years we have seen in the Russian medical literature a number of works of profound content and originality, such as "Introduction to Thanatology" by Prof. Shore and the aforementioned "Mechanics of Vital Signs of the Sick Man" by Prof. Neviadomsky.
