The prevalence of DM in Riskesdas in 2018 according to the Perkeni consensus in 2015 is higher than according to the Perkeni consensus in 2011, the prevalence was10.9%. The disease can develop into diabetes nephropathy, Increased prevalence of diabetic nephropathy directly proportional with an increase in diabetes prevalence. Diabetic nephropathy is a microvascular complication in diabetics that develops around 30% in patients with type I DM and about 40% in patients with type II DM. Turmeric extract has antioxidant and anti-inflammatory effects to prevent the bad development of diabetes nephropathy. This study looked at the effect of giving a combination of noni and turmeric extract on histopathology of alloxan-induced renal rats. A total of 25 mice were divided into 5 treatment groups, namely the PI group (250 mg / kgBB extract dose), PII group (500 mg / kgBB extract dose), PIII group (750 mg / kgBB extract dose), positive control group (glibenklamid) and negative control group (without extract and glibenklamid). The study used Post Test Only Group. The highest percentage decrease in blood glucose in the PI group was 56.11% and the lowest decrease in the PIII group was 24.12% with p = 0.012. The results of the study were not based on the number of extract doses. The measurement results of rat body weight and glomerular diameter were not affected by blood glucose level with p = 0.700 for body weight and p = 0.187 for glomerular measurement results.

Antiviral treatments inhibiting Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication may represent a strategy complementary to vaccination to fight the ongoing Coronavirus disease 19 (COVID-19) pandemic. Molecules or extracts inhibiting the SARS-CoV-2 chymotripsin-like protease (3CLPro) could contribute to reducing or suppressing SARS-CoV-2 replication. Using a targeted approach, we identified 17 plant products that are included in current and traditional cuisines as promising inhibitors of SARS-CoV-2 3CLPro activity. Methanolic extracts were evaluated in vitro for inhibition of SARS-CoV-2 3CLPro activity using a quenched fluorescence resonance energy transfer (FRET) assay. Extracts from turmeric (Curcuma longa) rhizomes, mustard (Brassica nigra) seeds, and wall rocket (Diplotaxis erucoides subsp. erucoides) at 500 µg mL−1 displayed significant inhibition of the 3CLPro activity, resulting in residual protease activities of 0.0%, 9.4%, and 14.9%, respectively. Using different extract concentrations, an IC50 value of 15.74 µg mL−1 was calculated for turmeric extract. Commercial curcumin inhibited the 3CLPro activity, but did not fully account for the inhibitory effect of turmeric rhizomes extracts, suggesting that other components of the turmeric extract must also play a main role in inhibiting the 3CLPro activity. Sinigrin, a major glucosinolate present in mustard seeds and wall rocket, did not have relevant 3CLPro inhibitory activity; however, its hydrolysis product allyl isothiocyanate had an IC50 value of 41.43 µg mL−1. The current study identifies plant extracts and molecules that can be of interest in the search for treatments against COVID-19, acting as a basis for future chemical, in vivo, and clinical trials.

The aim of the study was to evaluate the effects of turmeric supplementation on selected quality features, oxidative stability, and the safety of duck meat burgers. Four burger variants, namely I–control, no additive, II–with turmeric powder, III–with turmeric extract, and IV–with turmeric paste, were tested. The pH, WHC, colour parameters on the CIE L*a*b* scale, finished products’ shear force, TBARS index, and the total number of microorganisms were determined while performing sensory evaluations. Tests were carried out after 24 h, 6, 12, and 18 days of refrigerated storage (4 ± 2 °C). The addition of turmeric powder and paste significantly limited lipid oxidation processes in vacuum-packed duck meat burgers over an 18-day period. Although lipid oxidation processes accelerated after 6 days in all burger variants, burgers with powdered turmeric powder showed the lowest TBARS index values and limited total microorganism increases. Turmeric paste and powder additions resulted in decreased pH, increased water retention, and lighter colouration in refrigerated products. These additives were deemed acceptable during sensory evaluation. The most desirable aroma and taste, including juiciness, were in burgers with turmeric paste addition, while burgers with powdered additions were rated higher for their desired aroma and intensity of taste.

Введение. Востребованным для лечения болезни Крона (БК) является разработка новых, обоснованных с патогенетических позиций и безопасных лекарственных средств преимущественно локального действия эндогенного или растительного происхождения. В этом отношении привлекает внимание экстракт корневищ Куркумы длинной (Curcuma longa), содержащий куркуминоидный комплекс, обладающий плейотропными эффектами. Ранее нами показано, что экстракт куркумы в составе суппозиториев при экспериментальной БК обладaет иммуномодулирующим и местным антиоксидантным действием, что предполагает влияние экстракта куркумы на морфологию очага повреждения в кишечнике при БК. Цель работы - изучение влияния экстракта куркумы в составе оригинальных ректальных суппозиториев на динамику морфологических изменений, экспрессию миелопероксидазы (МПО) и TNF-a в очаге повреждения толстого кишечника при экспериментальной БК. Методика. Эксперимент выполнен на 49 половозрелых крысах-самцах Wistar. БК моделировали введением per rectum спиртового раствора тринитробензосульфоновой кислоты (ТНБС). Оригинальные ректальные суппозитории массой 300 мг на основе полиэтиленгликолей различной молекулярной массы, содержащие 0,075 мг куркумина из экстракта корневищ Curcuma longa L., вводили per rectum каждые 12 ч в течение 7 сут. Клинический статус оценивали по модифицированной шкале Disease activity index (DAI). Морфометрически в стенке кишечника оценивали размер язвенного дефект, выраженность клеточной инфильтрации, рассчитывали индекс тканевого повреждения (tissue damage index, TDI), оценивали экспрессию МПО и TNF-α. Результаты. При экспериментальной БК на 3-и, 5-е и 7-е сут наблюдения в толстом кишечнике обнаруживались язвенные дефекты, выраженный отек тканей, плотная нейтрофильно-лимфоцитарная инифильтрации с примесью эозинофилов, плазмоцитов, гистиоцитов, фибробластов, наблюдалось формирование грануляционной ткани. Индекс тканевого повреждения возрастал, повышалась экспрессия МПО и TNF-α. Размер язвенных дефектов, выраженность инфильтрации, индекс тканевого повреждения соответствовали клинической картине и индексу DAI. Применение оригинальных ректальных суппозиториев с экстрактом куркумы (0,075 мг) приводит к снижению выраженности клинических и морфологических признаков заболевания, максимальный эффект отмечен на 5-е и 7-е сут наблюдения. Заключение. Установленные протекторные свойства куркумина в составе оригинальных ректальных суппозиториев при БК на доклиническом этапе расширяют современные представления о плейотропных эффектах экстракта куркумы и являются предпосылкой для проведения дальнейших исследований и внедрения новой лекарственной формы в клиническую практику. The development of safe, new, pathogenetically justified medicines, mainly with local effects and of endogenous or plant origin, is of great interest for treatment of Crohn’s disease (CD). In this regard, an extract of rhizomes of Curcuma longa, containing a curcuminoid complex with pleiotropic effects, has attracted attention. We showed previously that having turmeric extract in suppositories for treatment of experimental CD would produce immunomodulatory and antioxidant effects. This suggests that turmeric extract affects the morphology of the CD intestinal lesion. The aim of this work was to study the effect of turmeric extract in the composition of novel rectal suppositories on the morphology and expression of myeloperoxidase (MPO) and TNF- α in colon lesions of experimental CD. Methods. Experiments were performed on 49 sexually mature male Wistar rats. CD was modeled by administration per rectum of an alcohol solution of trinitrobenzenesulfonic acid. The newly formulated rectal suppositories weighing 300 mg and based on polyethylene glycols of various molecular weights and containing 0.075 mg of curcumin obtained from Curcuma longa L. rhizome extract were administered per rectum every 12 hours for 7 days. The clinical status was assessed with the modified disease activity index (DAI) scale. The ulcer defect diameter, cell infiltration, tissue damage index (TDI), MPO expression, and TNF-α expression were evaluated. Results. In experimental CD on the 3rd, 5th, and 7th days of observation, a morphometric assessment of the lesion in the large intestine revealed the presence of ulcerative defects, edema, thick neutrophilic lymphocytic infiltration with an admixture of eosinophils, plasmocytes, histiocytes, fibroblasts, the formation of granulation tissue, increased TDI, and increased expression of MPO and TNF-α. The size of ulcerative defects, the degree of wall infiltration by neutrophils, lymphocytes, plasmocytes, histiocytes, and fibroblasts were recorded. The TDI, the expression of MPO, and TNF-α were associated with the DAI. The use of the novel rectal suppositories produced a maximal effect on the 5th and 7th days of observation. The severity of clinical and morphological signs of the disease were reduced. These signs included ulcer size, TDI, intestinal wall infiltration with neutrophils, lymphocytes, eosinophils, plasmocytes, histiocytes, and fibroblasts, and expression of MPO and TNF-α. Conclusion. The results supplement available data on the pathogenesis, the role of the expression of MPO and TNF-α, and the morphology of the lesion in the clinical status in TNBS-induced CD in rats. The demonstrated, protective properties of curcumin in the composition of the novel rectal suppositories at the preclinical stage of CD expand modern understanding of the pleiotropic effects of turmeric extract and are a prerequisite for further research and the introduction of a new dosage form in clinical practice.

Purpose: The purpose of this study was to determine the ways and objectives of the use of turmeric by Balinese, as well as the phytochemical content and antioxidant capacity of turmeric extract which is traditionally processed in Bali. Research methods: The method and purpose of utilizing turmeric were obtained through observation and interviews with 900 Balinese respondents. Quantitative phytochemical tests include starch, protein, flavonoid, tannin, phenol and vitamin C levels and qualitatively for the presence of triterpenes, steroids, alkaloids, and saponins. Antioxidant capacity was measured using the DPPH method. Findings: Through this research, we found there were only 36.8% of respondents had ever used turmeric as a traditional medicine. Utilization of turmeric was mostly in the form of loloh or traditional drinks. Phytochemical test results showed turmeric extract had 67.38% starch, 3.42% protein, 2709.39 mg/100 gr flavonoids, tannins 291.64 mg/100gr, phenol 1584.04 mg/100 gr, and vitamin C 0.06 mg/100gr. Qualitatively, turmeric extract contained triterpenes, alkaloids, and saponins, but did not contain steroids. The antioxidant capacity of turmeric extract was 70.9 mg/L GAEAC. Implications: Turmeric extract is a traditional medicine made from nature that is most commonly used by Balinese and very potential to be developed as an antibacterial, antioxidant, anti-inflammatory, or other benefits that still need further investigation.
