Study of total antioxidant capacity of red raspberry (Rubus idaeous L. ) shoots. / Estudio de la capacidad antioxidante total de brotes de frambuesa roja (Rubus idaeous L. ).

Background: Today, cardiovascular, oncological, and neurodegenerative diseases are the main causes of death in the world, according to official World Health Organization (WHO) statistics. Antioxidants are used to treat and prevent these diseases. In order to develop optimal technology for obtaining drugs based on plant extracts with antioxidant action, it is necessary to determine the total antioxidant capacity of raspberry shoots. Objectives: The study aimed to determine the total antioxidant capacity of red raspberry shoots, study the content of biologically active substances (BAS), and the antioxidant activity of red raspberry shoot extracts obtained during subsequent exhaustive extraction. Methods: The number of phenolic compounds, catechins, flavonoids, and hydroxycinnamic acids was determined by a spectrophotometric analysis method, whereas organic acids were determined by the alkalimetric method in red raspberry shoot extracts; the antioxidant activity of obtained extracts was evaluated by potentiometric method. Results: The total antioxidant capacity of red raspberry shoots was 164.12 mmol-equiv./m dry weight, the sum of the total content of phenolic compounds was 24.40 mg gallic acid (GA)/mL, catechins ­ 21.36 mg epigallocatechin-3-O-gallate (EGCG)/mL, flavonoids ­ 0.77 mg rutin (R)/mL, hydroxycinnamic acids derivatives ­ 2.56 mg chlorogenic acid (ChA)/mL and organic acids ­ 1.88 mg citric acid (CA)/mL in red raspberry shoot extracts obtained during subsequent exhaustive extraction. The analysis showed that there is a very high positive correlation between antioxidant activity and total phenolic compounds, catechin, flavonoid, hydroxycinnamic acids derivatives, and organic acids content in red raspberry shoot extracts. Conclusions: Total red raspberry shoots' antioxidant capacity has been determined. The study results can be used to develop optimal technology for obtaining drugs based on the extract of red raspberry shoots, which has an antioxidant effect

Contexto: Hoy en día, las enfermedades cardiovasculares, oncológicas y neurodegenerativas son las principales causas de muerte en el mundo según estadísticas oficiales de la Organización Mundial de la Salud OMS. Los antioxidantes se utilizan para tratar y prevenir estas enfermedades. Para desarrollar una tecnología óptima para la obtención de fármacos a base de extractos de plantas con acción antioxidante, es necesario determinar la capacidad antioxidante total de los brotes de frambuesa.Objetivos: El estudio tuvo como objetivo determinar la capacidad antioxidante total de los brotes de frambuesa roja, estudiar el contenido de sustancias biológicamente activas (SBA) y la actividad antioxidante de los extractos de brotes de frambuesa roja obtenidos mediante extracción exhaustiva. Métodos: La cantidad de compuestos fenólicos, catequinas, flavonoides y ácidos hidroxicinámicos se determinó por método de análisis espectrofotométrico, mientras que los ácidos orgánicos por método alcalimétrico en extractos de brotes de frambuesa roja; La actividad antioxidante de los extractos obtenidos se evaluó por método potenciométrico. Resultados: La capacidad antioxidante total de los brotes de frambuesa roja fue de 164.12 mmol-equiv./m de peso seco, la suma del contenido total de compuestos fenólicos fue de 24.40 mg gálico ácido (GA)/mL, catequinas ­ 21.36 mg epigalocatequina-3-O-galato (EGCG)/mL, flavonoides ­ 0.77 mg rutina (R)/mL, derivados de ácidos hidroxicinámicos ­ 2.56 mg clorogénico ácido (ChA)/mL y ácidos orgánicos ­ 1.88 mg cítrico ácido (CA)/mL en extractos de brotes de frambuesa roja obtenidos durante extracción exhaustiva. La correlación analizada mostró que existe una correlación positiva entre la actividad antioxidante y el contenido de compuestos fenólicos totales, catequinas, flavonoides, derivados de ácidos hidroxicinámicos y ácidos orgánicos en extractos de brotes de frambuesa roja. Conclusiones: Gracias a nuestros resultados se ha determinado la capacidad antioxidante total de los brotes de frambuesa roja. Los resultados del estudio se pueden utilizar para desarrollar una tecnología óptima para la obtención de fármacos basados en el extracto de brotes de frambuesa roja, que tiene un efecto antioxidante

Realities of Pharmaceutical Compounding in the Republic of Uzbekistan.

The development of compounding science in the Republic of Uzbekistan began in ancient times. The emergence of medical science on the territory of modern Uzbekistan was associated with the activities of the famous physician Ibn Sina (Avicenna). His Canon of Medicine is still considered the main source of medical knowledge in the world. He paid great attention to herbal medicines, its collection, storage, and application. The main development of compounding in Uzbekistan fell within the 20th century, after the Main Directorate of Pharmacies was established and new pharmacies were opened in all cities. In the beginning of 1975, there were about 2000 pharmacies in Uzbekistan and all pharmacies were engaged in the preparation of medicines. Today, there are more than 14 thousand pharmacies in Uzbekistan, which belong to large pharmacy chains, in the structure of which there are compounding pharmacies that compound injections and infusions, nasal and eardrops, ointments and suppositories, tinctures, decoctions, etc. Among the pharmaceutical networks in Uzbekistan, JSC Dori-Darmon is one of the largest. JSC Dori-Darmon, having about 120 branches, provides the population of Uzbekistan with medicines. Another one, Osiyo Farm, specializes in the compounding of external solutions and semi-solid dosage forms, while JSC Dori- Darmon mainly dispenses injections, mixtures, and solutions for external use. In Uzbekistan, pharmaceutical compounding is regulated by the Law of the Republic of Uzbekistan No. 415-I. The development of the pharmaceutical market in Uzbekistan is very active since the number of pharmaceutical enterprises is increasing and new drugs of synthetic and herbal origin are being developed. The main educational institutions that train pharmacists are the Tashkent Pharmaceutical Institute and the Tashkent Medical College.

Multiple myeloma: challenges of differential diagnosis (clinical case).

The objective of our study was to interpret and discuss atypical multiple myeloma case. The article describes the case of clinical observation of a patient K, in which manifestations of chronic kidney disease and circulatory failure prevailed in clinical picture of the disease. The authors recommended an X-ray examination of skull and pelvic bones as a screening method suitable for elderly people with symptoms of chronic renal insufficiency and chronic bone and muscle pain resistant to treatment.
