RESUMO

This study aimed to evaluate the efficacy and safety of various oral Chinese patent medicines in the adjuvant treatment of rotavirus gastroenteritis(RVGE) in children based on network Meta-analysis. Randomized controlled trial(RCT) of oral Chinese patent medicine in the adjuvant treatment of RVGE in children was retrieved from the databases such as CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, EMbase, and Web of Science from database inception to October 22, 2022. The quality of the included RCT was evaluated according to the Cochrane risk-of-bias tool, and the data were analyzed by RevMan 5.4 and Stata 16 software. Sixty-three RCTs were included, with 11 oral Chinese patent medicines involved, including Xingpi Yanger Granules, Weichang'an Pills, Qiuxieling Mixture, Erxieting Granules, and Changyanning Granules/Syrup. The results of the network Meta-analysis showed that in terms of clinical total effective rate, the top 3 optimal interventions were Changyanning Granules/Syrup, Xiaoer Guangpo Zhixie Oral Liquid, and Xiaoer Shuangjie Zhixie Granules combined with conventional western medicine. In terms of the anti-diarrheal time, the top 3 optimal interventions were Shenling Baizhu Granules, Qiuxieling Mixture, and Shuangling Zhixie Oral Liquid combined with conventional western medicine. In terms of the antiemetic time, the top 3 optimal interventions were Changyanning Granules/Syrup, Xingpi Yanger Granules, and Xiaoer Shuangjie Zhixie Granules combined with conventional western medicine. In terms of the antipyretic time, the top 3 optimal interventions were Shenling Baizhu Granules, Xiaoer Shuangjie Zhixie Granules, and Qiuxieling Mixture combined with conventional western medicine. In terms of the negative conversion rate of rotavirus, the top 3 optimal interventions were Xingpi Yanger Granules, Erxieting Granules, and Cangling Zhixie Oral Liquid combined with conventional western medicine. In terms of reducing creatine kinase isoenzyme MB(CK-MB) level, the top 3 optimal interventions were Weichang'an Pills, Xingpi Yanger Granules, and Xiaoer Shuangjie Zhixie Granules combined with conventional western medicine. In terms of adverse reactions, no se-rious adverse reactions were reported in all studies. Oral Chinese patent medicines in the adjuvant treatment of children with RVGE have their own advantages, Specifically, Changyanning Granules/Syrup + conventional western medicine focuses on improving the clinical total effective rate and shortening the antiemetic time, Shenling Baizhu Granules + conventional western medicine on shortening the anti-diarrheal time and antipyretic time, Xingpi Yanger Granules + conventional western medicine on improving the negative conversion rate of rotavirus, and Weichang'an Pills + conventional western medicine on reducing the CK-MB level. Limited by the quantity and quality of literature included in this study, the results need to be verified by high-quality RCT with a larger sample size.

RESUMO

The present study aimed to investigate the effect of various adjuvant rice on the quality of rice-steamed Rehmanniae Radix(RSRR) with Japonica rice, millet, yellow rice, black rice, and glutinous rice as raw materials, and analyze the anti-osteoporosis effect of RSRR by the optimal adjuvant rice. On the basis of the established UPLC-MS/MS method for the determination of the content of catalpol and rehmannioside D, comprehensive weighted scoring method was employed to evaluate the effect of various auxiliary rice on the quality of RSRR with the content of catalpol and rehmannioside D, character score, and taste score as indicators to optimize adjuvant rice. The osteoporosis model was induced by ovariectomy in rats. SD rats were randomly divided into a sham operation group, a model group, a positive control group, and low-dose and high-dose groups of Rehmanniae Radix, RSRR, steamed Rehmanniae Radix, and Epimedii Folium-RSRR. After treatment for 12 weeks, body weight, bone calcium content, and bone mineral density were mea-sured. The results showed that Japonica rice was selected as the optimal adjuvant due to the highest comprehensive score of RSRR steamed by Japonica rice. Rehmanniae Radix, RSRR, steamed Rehmanniae Radix, as well as Epimedii Folium-RSRR, could improve osteoporosis by increasing bone calcium content and bone mineral density. RSRR was superior to Rehmanniae Radix in improving osteo-porosis. However, there was no significant difference between RSRR and steamed Rehmanniae Radix. This study confirmed that Japo-nica rice was the optimal adjuvant rice of RSRR and verified the anti-osteoporosis effect of RSRR, which laid a foundation for further research on the pharmacological action and mechanism of RSRR.

RESUMO

Essential oils(EOs) from Chinese medicinals, which can be used as adjuvants and exert certain therapeutic effect, are directly used in Chinese medicine formulas. Conventional research strategy for EOs from Chinese medicinals is to compare the efficacy of the prescriptions before and after the addition of EOs, and the penetration-enhancing mechanisms of EOs remain unclear. In modern research on EOs from Chinese medicinals, the method for studying chemical penetration enhancers is often used, which fails to reflect the overall efficacy of EOs. This study clarified the property regularity of EOs from Chinese medicinals as transdermal penetration enhancers, and thereby proposed a research model which integrated the medicinal and adjuvant properties of EOs from Chinese medicinals via "component-delivery-effect" characterization route. The core concept is that constituents of EOs from Chinese medicinals and their delivery process play a key role in their external application. This research model is expected to serve as a reference for further research on EOs from Chinese medicinals for transdermal application.

RESUMO

Processing of Chinese medicinals with vinegar is one of the characteristic processing techniques. Vinegar is vital for the quality of vinegar-processed decoction pieces. However, there have been no specified standards for adjuvants. Through consulting relevant literature and monographs, we comprehensively reviewed the historical evolution of processing with vinegar in records, selection and application of vinegar, and summarized the relevant standards and current status of vinegar as an adjuvant in China. According to the records in literature, vinegar is effective in activating blood, moving qi, dispersing blood stasis, removing toxin, promoting appetite, and nourishing the liver. Traditionally, rice vinegar is chosen in processing. Nowadays, the vinegar made from rice under solid-state fermentation should be chosen. At present, only food standards can be taken for reference for vinegar in the processing. Integrative and specific inspection indicators are lacking, so the standards for adjuvants need to be improved urgently. In addition, the inadequacy in quality control and management is also a major problem to be solved. Through literature research, we reviewed the historical evolution and research advance in vinegar to provide a reference for the standardization and further research of vinegar used in the Chinese medicinal processing.

RESUMO

To systematically evaluate the efficacy and safety of Huaier Granules in the adjuvant treatment of primary liver cancer. The databases of CNKI, Wanfang, VIP, CBMdisc, PubMed, Cochrane Library and EMbase were searched by computer to screen out the randomized controlled trial on Huaier Granules combined with Western medicine in the treatment of primary liver cancer from the establishment of the databases to January 2020. Data extraction and quality evaluation were conducted for the included literature. Meta-analysis was conducted with RevMan 5.3 software, and evidence quality evaluation was conducted for the outcomes by GRADE profiler software. A total of 24 articles were included, with a total sample size of 2 664 cases. Meta-analysis showed that as compared with Western medicine alone, Huaier Granules combined with Western medicine could improve the objective remission rate(RR=1.38, 95%CI[1.26, 1.51], P<0.000 01), disease control rate(RR=1.29, 95%CI[1.10, 1.52], P=0.002) and 6-month survival rate(RR=1.20, 95%CI[1.10, 1.32], P<0.000 1), 1-year survival rate(RR=1.39, 95%CI[1.23, 1.58], P<0.000 01), 2-year survival rate(RR=1.95, 95%CI[1.28, 2.96], P=0.002), KPS score(MD=17.15, 95%CI[6.47, 27.83], P=0.002) and the improvement rate of KPS score(RR=2.02, 95%CI[1.47, 2.77], P<0.000 1), AFP decline rate(RR=1.40, 95%CI[1.20, 1.62], P<0.000 1), CD3~+(MD=17.34, 95%CI[9.28, 25.40], P<0.000 1), CD4~+(MD=8.62, 95%CI[1.59, 15.64], P=0.02), CD8~+(MD=1.95, 95%CI[-3.93, 7.82], P=0.52), CD4~+/CD8~+(MD=0.42, 95%CI[-0.33, 1.17], P=0.27); reduce the level of AFP(MD=-71.57, 95%CI[-80.42,-62.72], P<0.000 01), recurrence rate(RR=0.76, 95%CI[0.67, 0.85], P<0.000 01), and incidence of adverse reactions(RR=0.60, 95%CI[0.41, 0.89], P=0.01) in patients with primary liver cancer. According to the GRADE system, the evidence for outcome measures was low to very low. The results show that Huaier Granules have certain efficacy and high safety in adjuvant treatment of primary liver cancer, but its effect in reducing adverse reactions and improve immunity remains to be verified. Due to the poor quality of the included studies and evidences, the conclusions still need to be further verified by multi-center, large sample, and randomized double-blind controlled studies.

RESUMO

Combined vaccines for childhood are a strategy in the prevention of several diseases. These can maximize protection and decrease immunization schedules in children. New candidates are getting closer to being able to meet these needs, but they raise numerous strategic questions related to formulation and regulatory aspects. In addition to being immunogenic and protective must have low reactogenicity when combined with other antigens. Adjuvants are important components in achieving these combinations. Therefore, a reactogenicity study was designed for two Bordetella pertussis formulations containing hydroxide or aluminum phosphate in Sprague Dawley rats. Both formulations dose were administered in 0.2 mL intramuscularly. Clinical evaluations, body weight, water consumption, food, temperature, muscle volume, dermal irritability and pathological studies with special interest at the inoculation site were carried out. Only differences in body temperature and muscle volume were found with a slight increase in values with return to normal. The macroscopic study showed lesions at the site of inoculation, consid­ered characteristics of aluminum adjuvants, such as granulomatous abscesses and the increase in regional lymph nodes near the inoculation site. As conclusion, there are no differences between the formulations of B. pertussis with hydroxide or aluminum phosphate resulted in low reactogenicity.


Las vacunas combinadas resultan una estrategia importante en la obtención de vacunas múltiples para la infancia y el uso de adyuvantes es un componente de gran valor en lograr estas combinaciones, además de ser inmunogénicas y protectoras deben tener baja reactogenicidad, cuando se combinan con diferentes antígenos. Por esta razón, se diseñó un estudio de reactogenicidad a dos formulaciones que contenían hidróxido y fosfato de aluminio con antígenos de Bordetella pertussis en ratas Sprague Dawley. Se administró a cada grupo de ensayo una dosis correspondiente de ambas formulaciones en 0,2 mL por vía intramuscular. Se realizaron observaciones clínicas, comportamiento del peso corporal, consumo de agua, alimentos, temperatura corporal, volumen muscular, irritabilidad dérmica y estudios anatomopatológicos macroscópicos, con especial interés en el sitio de inoculación. No se observaron síntomas, ni muertes en los animales durante el estudio. Tampoco se encontraron diferencias entre los grupos experimentales en cuanto al peso corporal, el consumo de agua y de alimentos; los estudios de temperatura corporal y volumetría muscular evidenciaron un ligero incremento en los valores, los cuales involucionaron rápidamente a la normalidad. En el estudio anatomopatológico macroscópico se observaron lesiones a nivel del punto de inoculación, consideradas propias de los adyuvantes que contienen aluminio, tales como formaciones abscedadas de tipo granulomatosas y el aumento de los ganglios linfáticos regionales cercanos al punto de inoculación. Se concluye que las formulaciones en hidróxido y fosfato de aluminio con antígenos de B.pertussis resultaron ser de baja reactogenicidad.

RESUMO

To systemically evaluate the benefits and side effects of Shensong Yangxin Capsules( SYC) in the adjuvant treatment of stable angina pectoris( SAP). Chinese and English databases( PubMed,EMbase,the Cochrane Library,CBM,CNKI,VIP,Wan Fang database) were retrieved to collect the randomized controlled trials( RCTs) about therapeutic efficacy of SYC combined with routine drug( trial group) vs routine drug( control group) in the treatment of SAP. The methodological quality of the RCTs was evaluated based on the cochrane risk of bias assessment tool. The data were extracted and Meta-analyzed by Reviewer Manager 5. 3. TSA 0. 9 software was used for trial sequential analysis( TSA) of the total effective rate of symptoms improvement. A total of 15 RCTs with 1 316 participants were included. RESULTS:: of Meta-analysis showed that the total effective rate of angina symptoms improvement( RR = 1. 15,95% CI[1. 09,1. 21],P<0. 001) of trial group were significantly higher than those of control group,with statistical significance,the total effective rate of electrocardiograms( ECG) improvement( RR = 1. 10,95% CI[0. 94,1. 29],P = 0. 25) of trial group were significantly higher than those of control group,but the difference was not statistically significant. After treatment,the improvement of the total time of 24 h general ischemia( SMD =-1. 21,95%CI[-1. 97,-0. 45],P = 0. 002),the ST-segment depression amplitude( SMD =-1. 30,95%CI [-1. 52,-1. 09],P<0. 001),the duration of angina pectoris attack( SMD =-1. 16,95% CI[-1. 36,-0. 95],P< 0. 001),the angina pectoris attack every week( SMD =-0. 80,95%CI[-1. 10,-0. 50],P<0. 001),the onsumption of nitroglycerin every week( SMD=-0. 72,95%CI[-1. 05,-0. 39],P<0. 001) in the trial group were better than that of the control group,and the difference was statistically significant. Besides,the improvement of the blood lipid and high sensitivity C reactive protein( hs-CRP) in the trial group were better than those of the control group after treatment,and the difference was statistically significant( P< 0. 001). Funnel plots and Egger's linear regression showed that there was no publication bias. By sensitivity analysis,it showed that the results of this study were stable and reliable. No obvious adverse drug reactions were observed in all studies. TSA analysis showed that the evidence of Meta-analysis was reliable. SYC combined with routine Western medicine treatment for SAP can improve the total effective rate of angina pectoris,reduce 24 h total ischemia time,ST segment depression amplitude,duration of angina pectoris attack,frequency of angina pectoris attack and nitroglycerin dosage,and also can improve blood lipid and hs-CRP levels.

RESUMO

The use of adjuvants associated with herbicides aims at improving the performance of application and the consequent increase in the biological effect of the treatment. However, the sequence of product added to the sprayer tank can influence the phytosanitary spray solution. Thus, this study aimed to evaluate the control of Senna obtusifolia as a function of the sequence of addition of the herbicide aminopyralid + fluroxypyr and adjuvants in the preparation of spray solution. Two herbicide doses (1 and 2 L c.p. ha-1) associated with the adjuvants mineral oil (MO), silicone polyether copolymer (SIL), and a mixture of phosphatidylcholine and propionic acid (LEC), all in the proportion of 0.3% v v-1, with alternate addition to the spray solution to evaluate the effects of the preparation sequence. The spray solution volume considered was 150 L ha-1. Evaluations of spray solution stability were performed from the visual evaluation of homogeneity, electrical conductivity, and pH. The effect of treatment on S. obtusifolia control was measured using a scoring scale and dry matter. Correlation coefficients between the evaluations were also determined. No difference of the preparation sequence of spray solution was observed for stability, pH, and electrical conductivity, but an influence was observed on S. obtusifolia control, without changing dry matter accumulation. The treatment with the adjuvant LEC previously added to the herbicide provided a higher control rate at the highest dose, while the adjuvant SIL had the opposite effect.(AU)


O uso de adjuvantes associados a herbicidas visa melhorar o desempenho da aplicação e o consequente aumento do efeito biológico do tratamento. Porém, a ordem de adição dos produtos ao tanque do pulverizador pode trazer importantes influências à calda fitossanitária. Assim, o objetivo desta pesquisa foi avaliar o controle de Senna obtusifolia em função da sequência de adição do herbicida aminopiralide + fluroxipir e de adjuvantes no preparo das caldas. Foram utilizadas duas dosagens de herbicida (1 e 2 L p.c. ha-1), associadas aos adjuvantes óleo mineral (OM); copolímero de poliéter e silicone (SIL); mistura de fosfatidicolina e ácido propiônico (LEC), todos na proporção de 0,3% v v-1, com adição alternada à calda para avaliar os efeitos da sequência de preparo. O volume de calda considerado foi de 150 L ha-1. Foram realizadas avaliações da estabilidade da calda a partir da avaliação visual de homogeneidade, condutividade elétrica e pH. O efeito do tratamento no controle de S. obtusifolia foi mensurado por meio de uma escala de pontuação e pela massa seca. Também foram determinados os coeficientes de correlação entre as avaliações. Verificou-se que não houve diferença da sequência de preparo da calda para a estabilidade, o pH e a condutividade elétrica. Porém, a sequência de preparo influenciou o controle inicial de S. obtusifolia, sem efeito sobre a massa seca. O tratamento com o adjuvante LEC adicionado ao herbicida proporcionou maior taxa de controle na maior dosagem, enquanto o adjuvante de SIL teve o efeito oposto.(AU)

RESUMO

Este trabalho propôs o uso do fármaco quelante mesilato de desferroxamina (DFO) como agente adjuvante para estabilização química e microbiológica de formulações. Soluções de ácido ascórbico (AA) 5,0% (p/v) foram preparadas com sistemas antioxidantes constituídos por diferentes combinações de DFO, ácido etilenodiamino tetra-acético (EDTA) e metabissulfito de sódio, cada adjuvante na concentração máxima de 0,1% (p/v). Os sistemas foram testados previamente quanto à atividade antioxidante, mediante adição de um complexo de ferro (III) redox-ativo e ensaio baseado em fluorescência. Os sistemas também foram associados ao metilparabeno e avaliados quanto à atividade antimicrobiana pelo método turbidimétrico, utilizando-se a técnica de microdiluição em meios líquidos e cepas padrão de bactérias e fungos, incluindo S. aureus (ATCC 6538), E. coli (ATCC 8739), P. aeruginosa (ATCC 9027), C. albicans (ATCC 10231) e A. brasiliensis (ATCC 16404). As soluções de AA foram expostas a condições de teste de estabilidade acelerada e avaliadas quanto à estabilidade química, empregando-se método volumétrico validado para quantificar AA. Verificou-se que o EDTA foi o agente quelante que melhor contribuiu na estabilidade química da solução de AA, entretanto, o DFO apresentou desempenho muito superior ao EDTA para bloquear a atividade pró-oxidante do ferro. Além disso, o DFO foi fator relevante na inibição do crescimento microbiano e demonstrou sinergia com o metilparabeno. A otimização estatística dos resultados indicou que o uso do DFO nos sistemas antioxidante e conservante pode reduzir consideravelmente a concentração dos adjuvantes convencionais, EDTA, metabissulfito e metilparabeno, os quais são muitas vezes associados a reações de hipersensibilidade ou a danos ao meio ambiente


In this work it was proposed the use of the chelating drug desferroxamine mesylate (DFO) as adjuvant for chemical and microbiological stabilization of formulations. Ascorbic acid (AA) solutions 5.0% (w/v) were prepared with antioxidant systems containing different combinations of DFO, ethylenediaminetetraacetic acid (EDTA) and sodium metabisulphite, using a maximum concentration of 0.1% (w/v) for each adjuvant. Previously, the systems were spiked with a redox-active iron (III) complex and tested for antioxidant activity by fluorescence-based assay. The systems also were associated with methylparaben and evaluated for antimicrobial activity by turbidimetric method, using the microdilution technique and standard strains of bacteria and fungi, including S. aureus (ATCC 6538), E. coli (ATCC 8739), P. aeruginosa (ATCC 9027), C. albicans (ATCC 10231) and A. brasiliensis (ATCC 16404). The AA solutions were exposed to accelerated stability test conditions and evaluated for chemical stability, using a volumetric method that was validated to quantify AA. It was found that EDTA was the chelating agent that most contributed to the chemical stability of AA solution, however, DFO demonstrated a much higher performance to EDTA to block the pro-oxidant activity of iron. In addition, DFO was a relevant factor in the inhibition of microbial growth and showed synergy with methylparaben. The statistical optimization of the results indicated that the use of DFO in the antioxidant and preservative systems might considerably reduce the concentration of the conventional adjuvants, EDTA, metabisulphite and methylparaben, which are often associated with hypersensitivity reactions or environmental damage

RESUMO

La aplicación de sustancias con fines estéticos de forma indiscriminada como aceites minerales, hidrocarburos, silicona industrial, entre otros, llevan a producir enfermedades en el organismo bien sea locales y/o sistémicas. La asociación entre el uso de estas sustancias y la aparición de enfermedades autoinmunes aún no está clara. No obstante, se han descrito series de pacientes con antecedentes de inyección por materiales de relleno con fines cosméticos, que posteriormente presentaron patologías autoinmunes como: la esclerosis sistémica, el lupus eritematoso sistémico, la artritis reumatoidea, el síndrome de Sjögren, fibromialgia y presencia aislada de algunos síntomas inespecíficos como artralgias, mialgias, deterioro cognitivo, malestar general y fiebre. La reacción inflamatoria excesiva que pueden desencadenar estas sustancias y sus graves consecuencias para el organismo y teniendo en cuenta el aumento de estas prácticas a nivel global, hace necesario concientizar que sólo a través de una adecuada educación a la comunidad y la preparación del personal de la salud, podrá combatirse el terrible daño que provocan en la población(1)


The application of substances with aesthetic purpose in an indiscriminate way as oils minerals, hydrocarbons, industrial silicon, and others, they take to produce illnesses well in the body it is local and/or systemic. The association between the use of these substances and the appearance of autoimmunity diseases is not still clear. Nevertheless cases series have been described patient with antecedent of injection for filler materials with cosmetics purpose that later presented defined autoimmunity such as systemic sclerosis, lupus, rheumatoid arthritis, Sjögren Syndrome, Fibromyalgia and the isolated presence of some symptoms nonspecific. The excessive inflammatory reaction that can cause these substances and their serious consequences for the organism, and keeping in mind the increase from these practices to global level is necessary to inform that alone through an appropriate education to the community and the preparation of the health professionals will be able to prevent and combat the terrible damage in the population(1)

RESUMO

Ginger juice, a commonly used adjuvant for Chinese materia medica, is applied in processing of multiple Chinese herbal decoction pieces. Because of the raw materials and preparation process of ginger juice, it is difficult to be preserved for a long time, and the dosage of ginger juice in the processing can not be determined base on its content of main compositions. Ginger juice from different sources is hard to achieve consistent effect during the processing of traditional Chinese herbal decoction pieces. Based on the previous studies, the freeze drying of ginger juice under different shelf temperatures and vacuum degrees were studied, and the optimized freeze drying condition of ginger juice was determined. The content determination method for 6-gingerol, 8-gingerol, 10-gingerol and 6-shagaol in ginger juice and redissolved ginger juice was established. The content changes of 6-gingerol, 8-gingerol, 10-gingerol, 6-gingerol, 6-shagaol, volatile oil and total phenol were studied through the drying process and 30 days preservation period. The results showed that the freeze drying time of ginger juice was shortened after process optimization; the compositions basically remained unchanged after freeze drying, and there was no significant changes in the total phenol content and gingerol content, but the volatile oil content was significantly decreased(<0.05). Within 30 days, the contents of gingerol, total phenol, and volatile oil were on the decline as a whole. This study has preliminarily proved the feasibility of freeze-drying process of ginger juice as an adjuvant for Chinese medicine processing.

RESUMO

Based on the fact that chromogenic reaction of blue complex, a reaction product which can be dissolved in organic solvents, can be realized by polyethoxy and ammonium thiocyanate in tween 80, a rapid and accurate way for the determination for tween 80 in pharmaceutical adjuvant was established in this study, providing reliable technical means for quality control of traditional Chinese medicine injections. Based on the study of reaction kinetics, chromogenic reaction temperature and time, as well as extraction of organic solvents and other key conditions were optimized, and Kumu injection was used as the test material for method validation and applicability investigation. It was finally determined that 3 mL ammonium thiocyanate solution was added in the sample solution, and the reaction was carried out in a boiling water bath for 2 h. After cooling to room temperature, 5 mL of dichloromethane was added to extract the chromogenic product. The absorbance value was measured at the wavelength of 623 nm to calculate the tween 80 content in the sample. Under optimized conditions, tween 80 solution showed a good linear relationship with the absorbance in the range from 0.8 mg to 3.0 mg. The linear regression equation was =0.258-0.047. The correlation coefficient was 0.999 6. Under the experimental conditions, the average recovery was 99.66%, and the precision RSD was less than 2.0%. The results showed that this method can quickly and accurately determine the content of tween 80 in Kumu injection, and it could be applicable to the quality control of traditional Chinese medicine injections.

RESUMO

Resumen Introducción. Las tiosemicarbazonas y sus complejos de paladio (II) poseen actividad antineoplásica con pocos efectos secundarios, por lo cual se las considera como una nueva alternativa terapéutica. Sin embargo, existen diferencias en los rangos de la concentración inhibitoria media (CI50) asociada a la divergencia estructural y la solubilidad de los complejos, así como a la sensibilidad de los blancos celulares. La inclusión de fármacos en la beta-ciclodextrina con fines terapéuticos ha mejorado su solubilidad y estabilidad, pero los efectos de su combinación con los complejos de paladio (II) y las tiosemicarbazonas no se han comprobado aún. Objetivo. Estudiar el efecto citotóxico de los complejos de paladio en la beta-ciclodextrina. Materiales y métodos. La actividad citotóxica de los complejos de paladio en la beta-ciclodextrina se evaluó en la línea celular de cáncer de mama (MCF-7), empleando el método de la sulforodamina B. Resultados. Los ligandos MePhPzTSC y Ph2PzTSC, sus complejos de paladio (II) libres e incluidos en la beta-ciclodextrina y el cisplatino mostraron actividad citotóxica en la línea celular MCF-7; sin embargo, la citotoxicidad fue mayor con la inclusión en la beta-ciclodextrina ([Pd(MePhPzTSC)2]•ß-CD y [Pd(Ph2PzTSC)2]•ß-CD). La concentración inhibitoria media (CI50) para estos complejos se obtuvo en concentraciones de 0,14 y 0,49 μM, y con dosis hasta cinco veces inferiores comparadas con las concentraciones de los ligandos libres (1,4 y 2,9 μM), de los complejos de paladio (II) libres (0,57 y 1,24 μM) y del cisplatino (6,87 μM). Conclusiones. El uso de la beta-ciclodextrina mejoró significativamente la actividad citotóxica de las tiosemicarbazonas y sus complejos de paladio (II), lo cual probablemente está asociado al incremento de la solubilidad y biodisponibilidad del compuesto, estrategia que se puede sugerir para el diseño de futuros fármacos antineoplásicos.


Abstract Introduction: Thiosemicarbazones and palladium (II) complexes have antineoplastic activities with mild side effects, for which they are considered new alternative antineoplastic drugs. However, the IC50 ranges of these complexes vary due to differences in their structure and solubility and their sensitivities for various cellular targets. Beta-cyclodextrin is an additive used to improve the solubility and stability of various drugs for therapeutic use, but the combination of beta-cyclodextrin with palladium (II) complexes and thiosemicarbazones has not been tested yet. Objective: To study the cytotoxic effect of palladium (II) inclusion complexes in beta-cyclodextrin. Materials and methods: We tested the cytotoxic activity of palladium complexes combined with betacyclodextrin in the breast cancer cell line MCF-7 using a sulforhodamine B assay. Results: We tested the antiproliferative activity of palladium (II) complexes with and without the ligands MePhPzTSC and Ph2PzTSC and with and without beta-cyclodextrin in MCF-7 cells and compared them to that of cisplatin. All combinations showed antiproliferative activity; however, the activity was greater for the combinations that included beta-cyclodextrin: ([Pd (MePhPzTSC) 2] • ß-CD and [Pd (Ph2PzTSC) 2] • ß-CD), at concentrations of 0.14 and 0.49 μM, respectively. The IC50 for this complex was 5-fold lower than that of the ligand-free combinations (1.4 and 2.9 μM, respectively). The IC50 for free palladium (II) complex was 0.571.24 μM and that for cisplatin was 6.87 μM. Conclusions: Beta-cyclodextrin significantly enhanced the cytotoxic activities of palladium (II) complexes and thiosemicarbazones probably by improving their solubility and bioavailability. The addition of betacyclodextrin is a possible strategy for designing new anticancer drugs.

RESUMO

ABSTRACT Objectives This study evaluated the antimicrobial efficacy of ozone therapy in teeth contaminated with Pseudomonas aeruginosa, Enterococcus faecalis, and Staphylococcus aureus using a mono-species biofilm model. Parallel to this, the study aimed to evaluate the cytotoxicity of ozone for human gingival fibroblasts. Material and Methods: One hundred and eighty single-root teeth were contaminated with a mono-species biofilm of Enterococcus faecalis, Pseudomonas aeruginosa, and Staphylococcus aureus. Groups were formed: Group I – control; Group II – standard protocol; Group III – standard protocol + ozone gas at 40 µg/mL; and Group IV – standard protocol + aqueous ozone at 8 µg/mL. In parallel, human gingival fibroblasts were submitted to the MTT test. Cells were plated, then ozone was applied as follows: Group I (control) – broth medium; Group II – aqueous ozone at 2 µg/mL; Group III – aqueous ozone at 5 µg/mL; and Group IV – aqueous ozone at 8 µg/mL. Data were submitted to the Kruskal Wallis test and Bonferroni post hoc analyses to assess microbiology and cytotoxicity, respectively (p<0.05%). Results The results revealed antimicrobial efficacy by Group IV with no CFU count. The cytotoxicity assay showed Groups III and IV to be the most aggressive, providing a decrease in cell viability at hour 0 from 100% to 77.3% and 68.6%, respectively. Such a decrease in cell viability was reverted, and after 72 hours Groups III and IV provided the greatest increase in cell viability, being statistically different from Groups I and II. Conclusion According to the applied methodology and the limitations of this study, it was possible to conclude that ozone therapy improved the decontamination of the root canal ex vivo. Ozone was toxic to the cells on first contact, but cell viability was recovered. Thus, these findings suggest that ozone might be useful to improve root canal results.
