RESUMO
OBJECTIVE: This study evaluated the efficacy of Valeriana officinalis L. and Passiflora incarnata L. to control anxiety, surgical discomfort, and changes in vital signs of patients undergoing extraction of two unilateral third molars. MATERIALS AND METHODS: This study is a randomized, triple-blinded clinical trial. Fifty-four patients were allocated into three groups (Valeriana officinalis L., Passiflora incarnata L., and placebo). Anxiety levels were assessed using the State-Trace Anxiety Inventory (STAI) index, surgical discomfort using the QCirDental, and through the measurement of vital signs. The surgical times evaluated were before (T0), during (T1), and after surgery (T2). RESULTS: There was evidence that both Valeriana officinalis L. and Passiflora incarnata L., reduced STAY-S scores between T0 and T2 (p < .05), unlike placebo (p = .129). There was no change in surgical discomfort in all groups over time, and vital signs presented variable results. CONCLUSION: Phytotherapy drugs showed a reduction in anxiety state compared to the placebo group during third molar extraction procedure. CLINICAL TRIAL REGISTRATION: klRBR-6kcxvrc, March 10, 2022.

OBJECTIVE: The current study aimed to explore the potential protective effect of Passiflora Incarnata L., (PI) in treating IR injury after testicular torsion in rats. MATERIALS AND METHODS: This research investigated the impact of PI on IR damage in male Wistar albino rats. Animals were divided to three groups: group 1 (sham), group 2 (IR), and group 3 (IR+PI). RESULTS: The malondialdehyde (MDA), myeloperoxidase (MPO) and glutathione (GSH) levels did not significantly differ across the groups (p = 0.830, p = 0.153 and p=0.140, respectively). However, Group 3 demonstrated a superior total antioxidant status (TAS) value compared to Group 2 (p = 0.020). Concurrently, Group 3 presented a significantly diminished mean total oxidant status (TOS) relative to Group 2 (p = 0.009). Furthermore, Group 3 showed a markedly improved Johnsen score relative to Group 2 (p < 0.01). IR caused cell degeneration, apoptosis, and fibrosis in testicular tissues. PI treatment, however, mitigated these effects, preserved seminiferous tubule integrity and promoted regular spermatogenesis. Furthermore, it reduced expression of tumor necrosis factor-alpha (TNF-α), Bax, and Annexin V, signifying diminished inflammation and apoptosis, thereby supporting cell survival (p < 0.01, p < 0.01, p < 0.01, respectively). CONCLUSIONS: This study revealed that PI significantly reduces oxidative stress and testicular damage, potentially benefiting therapies for IR injuries.
OBJETIVO: Explorar el posible efecto protector de Passiflora incarnata L. (PI) en el tratamiento de la lesión por isquemia-reperfusión (IR) después de una torsión testicular en ratas. MÉTODO: Se estudió el impacto de Passiflora incarnata en el daño por IR en ratas Wistar albinas machos. Los animales se dividieron tres grupos: 1 (simulado), 2 (IR) y 3 (IR+PI). RESULTADOS: Los niveles de malondialdehyde (MDA), myeloperoxidase (MPO) y glutathione (GSH) no difirieron significativamente entre los grupos (p = 0.830, p = 0.153 y p = 0.140, respectivamente). Sin embargo, el grupo 3 tuvo un valor de estado antioxidante total (TAS) superior en comparación con el grupo 2 (p = 0.020). Al mismo tiempo, el grupo 3 presentó un estado oxidante total (TOS) medio significativamente disminuido en comparación con el grupo 2 (p = 0.009). El grupo 3 mostró una mejora notable en la puntuación de Johnsen en comparación con el grupo 2 (p < 0.01). La IR causó degeneración celular, apoptosis y fibrosis en los tejidos testiculares. El tratamiento con PI mitigó estos efectos, preservó la integridad de los túbulos seminíferos y promovió la espermatogénesis regular. Además, redujo la expresión de factor de necrosis tumoral alfa, Bax y anexina V, lo que significa una disminución de la inflamación y de la apoptosis, respaldando así la supervivencia celular (p < 0.01, p < 0.01 y p < 0.01, respectivamente). CONCLUSIONES: Este estudio reveló que PI reduce significativamente el estrés oxidativo y el daño testicular, beneficiando potencialmente las terapias para lesiones por IR.

As plantas medicinais foram os primeiros recursos terapêuticos obtidos pelos povos e há registros do seu uso em todos os momentos da História, por grande parte das civilizações. No Brasil, o uso das plantas medicinais é resultado dos conhecimentos de três populações: indígena, europeia e africana. O presente trabalho tem como objetivo caracterizar a manipulação mensal de um laboratório de fitoterápicos na cidade de Francisco Beltrão, Paraná. Os dados que foram coletados para a presente pesquisa são: número de cápsulas manipuladas mensalmente para cada um dos fitoterápicos, os quais serão obtidos a partir dos relatórios de manipulação de fitoterápicos mensais no ano de 2021 e individuais de cada unidade de saúde, fornecidos pela Secretaria de Saúde. Não havendo acesso a informações de pacientes e tampouco contato com eles. As informações dos relatórios foram tabuladas em planilha a fim de se estabelecer os três principais fitoterápicos manipulados no período preestabelecido. Trata-se de um estudo de campo, exploratório, documental e retrospectivo. Observamos que a média de manipulação foi de 34.029 cápsulas por mês, os fitoterápicos mais manipulados no ano de 2021, foram: Passiflora incarnata (maracujá), Aesculus hippocastanum (castanha da índia) e Curcuma longa. Também foi possível notar que houve um aumento gradual de dispensações após a capacitação dos profissionais, ocorrida entre junho e setembro. Além disso, verificamos que há uma grande diferença na quantidade dispensada por cada farmácia municipal, possivelmente devido ao nível de conhecimento dos profissionais de saúde e se preferem ou não prescrever aos pacientes.
Medicinal plants were the first therapeutic resources obtained by people and there are records of their use at all times of history, by a large part of civilizations. In Brazil, the use of medicinal plants is a result of the knowledge of three populations: indigenous, European and African. The present work aims to characterize the monthly handling of a plant medicine laboratory in the city of Francisco Beltrão, Paraná. The data that were collected for this research are: number of capsules handled monthly for each one of the phytotherapics, which will be obtained from the reports of handling of monthly phytotherapics in the year 2021 and individual of each health unit, provided by the Secretariat of Health. There is no access to patient information and no contact with them. The information in the reports was tabulated into a spreadsheet in order to establish the three main phytotherapics handled in the pre-established period. This is an exploratory, documentary and retrospective field study. We observed that the average handling was 34,029 capsules per month, the most manipulated phytotherapics in the year 2021, were: Passiflora incarnata (passion fruit), Aesculus hippocastanum (chestnut from India) and Curcuma longa. It was also possible to note that there was a gradual increase in dispensations after the training of professionals, which took place between June and September. In addition, we note that there is a big difference in the amount dispensed by each municipal pharmacy, possibly due to the level of knowledge of health professionals and whether or not they prefer to prescribe to patients.

RESUMO
An ultra-fast method for the simultaneous determination of heavy metals in Passiflora incarnata tea by capillary electrophoresis (CE) using a short-end injection combined with multivariate analysis was proposed. Separation was conducted by hydrodynamic injection (5 s at 0.5 psi) using the short-end injection procedure in a fused uncoated silica capillary (50 cm total length, 10.2 cm effective length, 50 µm i.d.) with separation time less than 2 min. An indirect UV detection at 214 nm was employed by using imidazole as a chromophore. The buffer used was 6 mmol/L hydroxybutyric acid (HIBA). The optimum conditions by full factorial with a central point were achieved by 18-crown-6 concentration (23.3 mmol L−1), voltage (+11.4 kV), methanol concentration (3.8%), and temperature (20 °C). The method showed good linearity (R2 > 0.998) for both Cd and Pb, inter-day precision of less than 14.49%, and an adequate limit of quantification only for Cd (LOQ < 0.5 µg mL−1 for Cd) based on the US Pharmacopeial Convention limit requirements for elemental impurities. After method validation, the method was applied to Passiflora incarnata tea samples from a local market. Furthermore, the developed method showed great potential for the determination of metals in other samples with proper sample preparation procedures.

OBJECTIVES: This study aimed to compare the effects of Passiflora incarnata, Erythrina mulungu, and midazolam in controlling anxiety in patients undergoing mandibular third molar extraction. METHODS: The volunteers underwent extraction of their third mandibular molars in a randomized, placebo-controlled, triple-blind, and parallel clinical trial. Passiflora incarnata (500 mg), Erythrina mulungu (500 mg), or midazolam (15 mg) was orally administered 60 min before the surgery. The anxiety level of participants was evaluated using questionnaires and measurements of physical parameters, including heart rate (HR), blood pressure (BP), and oxygen saturation (SpO2). RESULTS: A total of 200 volunteers were included in this clinical trial. Considering each procedure independently, no significant differences (p > 0.05) in BP, HR, and SpO2 were observed among the protocols. CONCLUSIONS: Passiflora incarnata showed a similar effect to midazolam but differed from placebo and mulungu, which were unable to control anxiety in this situation. Therefore, the results suggest that Passiflora configures an herbal medicine with an anxiolytic effect, adequate to use in third molar extractions. CLINICAL RELEVANCE: The use of Passiflora incarnata may be an alternative to benzodiazepines for controlling anxiety in patients scheduled for oral surgery under local anesthesia.

In the search for the reduction of the side effects caused by allopathy, phytotherapeutic products are already on the veterinary market. This study aimed was to evaluate Elevated Plus-Maze and Hole Board test as an analytical methodology for quality control of anxiolytic medicines based on Passiflora incarnata. The efficacy of three brands commercial differents of Passiflora incarnata extracts was tested in the Elevated Plus-maze (for anxiolytic effect) and the Hole Board test (for locomotor and neophilia activity) in Wistar rats. Treatment with the P. incarnata brands revealed a significant 3-fold increase in the length of stay in the open arms in the LCE. In the ambulation, animals from bands 1 and 3 presented a significant increase, being brand 2 the only one that did not present this relevance. In the neophilia, Passiflora brand 1 presented a significant increase of 3 times and groups 2 and 3 an increase of approximately 2 times. The results showed that different brands of Passiflora have a satisfactory quality standard related to biological activity and showed that the use of Elevated plus-maze/Hole board test can be an effective tool in the quality control of herbal medicines with anxiolytic activity associated with the phytochemical analysis.
Na busca pela redução dos efeitos colaterais causados pela alopatia, os fitoterápicos já se encontram disponíveis no mercado veterinário. O objetivo deste estudo foi avaliar os testes neurocomportamentais Labirinto em Cruz Elevado e Campo Vazado como metodologias analíticas para o controle de qualidade de medicamentos ansiolíticos a base de Passiflora incarnata. A eficácia de três diferentes marcas comerciais de extrato de Passiflora incarnata foi testada no Labirinto em Cruz Elevado (para efeitos ansiolíticos) e no Campo Vazado (para atividade locomotora e busca por novidade) em ratos Wistar. O tratamento com as marcas de P. incarnata demonstrou aumento significativo de 3 vezes no tempo de permanência nos braços abertos no Labirinto em Cruz Elevado. Na deambulação, animais das marcas 1 e 3 apresentaram aumento significativo, sendo a marca 2 a única que não apresentou relevância para este parâmetro. Na neofilia, a marca 1 de Passiflora apresentou aumento significativo de 3 vezes e as marcas 2 e 3 aumento de aproximadamente 2 vezes. Os resultados mostraram que diferentes marcas de Passiflora apresentam um padrão de qualidade satisfatório relacionado à atividade biológica e mostraram que a utilização dos testes Labirinto em Cruz Elevado e Campo Vazado podem ser ferramentas eficazes no controle de qualidade de fitoterápicos com atividade ansiolítica associadas à análises fitoquímicas.

Bacteria exhibiting beneficial traits like increasing the bioavailability of essential nutrients and modulating hormone levels in plants are known as plant growth promoting (PGP) bacteria. The occurrence of this specific group of bacteria in the endophytic environment may reflect the decisive role they play in a particular condition. This study aimed to determine the taxonomical diversity of the culturable bacterial endophytes, isolated in the vegetative stage of passionflower (Passiflora incarnata), and assess its potential to promote plant growth by phenotypic and genotypic approaches. The sequencing and phylogenetic analysis of the 16S rRNA gene allowed us to classify 58 bacterial endophytes into nine genera. Bacillus (70.7%) was the most dominant genus, followed by Pseudomonas (8.6%) and Pantoea (6.9%). A few isolates belonged to Rhodococcus and Paenibacillus, whereas the genera Lysinibacillus, Microvirga, Xanthomonas, and Leclercia were represented by only one isolate. The strains were tested for nitrogen fixation, phosphate solubilization, indole-acetic-acid synthesis, and siderophore production. Moreover, PGP related genes (nifH, ipdC, asb, and AcPho) were detected by PCR-based screening. Most of the isolates (94.8%) displayed a potential for at least one of the PGP traits tested by biochemical assays or PCR-based screening. Nine strains were selected based on results from both approaches and were evaluated for boosting the Cape gooseberry (Physalis peruviana) germination and growth. All tested isolates improved germination in vitro, and the majority (78%) increased growth parameters in vivo. The results suggested that most of culturable bacteria inhabiting P. incarnata in the vegetative stage could be used as probiotics for agricultural systems. Besides, their occurrence may be associated with specific physiological needs typical of this development stage.
RESUMO
Passiflora incarnata L. (Passifloraceae) has been traditionally used for treatment of anxiety, insomnia, drug addiction, mild infections, and pain. The aim of this study was to investigate the effect of a commercial extract of P. incarnata in the analgesia induced by alcohol withdrawal syndrome in rats. In addition, brain-derived neurotrophic factor and interleukin-10 levels were evaluated in prefrontal cortex, brainstem, and hippocampus. Male adult rats received by oral gavage: (1: water group) water for 19 days, 1 day interval and water (8 days); (2: P. incarnata group) water for 19 days, 1 day interval and P. incarnata 200 mg/kg (8 days); (3: alcohol withdrawal group) alcohol for 19 days, 1 day interval and water (8 days); and (4: P. incarnata in alcohol withdrawal) alcohol for 19 days, 1 day interval and P. incarnata 200 mg/kg (8 days). The tail-flick and hot plate tests were used as nociceptive response measures. Confirming previous study of our group, it was showed that alcohol-treated groups presented an increase in the nociceptive thresholds after alcohol withdrawal, which was reverted by P. incarnata, measured by the hot plate test. Besides, alcohol treatment increased brain-derived neurotrophic factor and interleukin-10 levels in prefrontal cortex, which was not reverted by P. incarnata. Considering these results, the P. incarnata treatment might be a potential therapy in the alcohol withdrawal syndrome. Copyright © 2017 John Wiley & Sons, Ltd.
