ABSTRACT

Background and Aims: The covid-19 pandemic has reversed years of progress in the fight to end tuberculosis. So, the discovery of new drugs as antituberculosis is very much needed. Our previous studies have shown that the extract of Centella asiatica is able to inhibit the growth of Mycobacterium tuberculosis in vitro and requires further research. The aims of this study is to prove the effect of Centella asiatica inhibit Mycobacterium tuberculosis in rat model tuberculosis. Method(s): The protocol in this study was approved by the veterinary ethics committee of Airlangga University. The rat tuberculosis model was induced by intrathecal injection of a suspension of Mycobacterium tuberculosis strain H37 Rv. Twenty-eight tuberculosis rat were randomly divided into four groups. Groups 1,2, and 3 were treated with ethanol extract of Centella asiatica at 375 mg/kgBW, 750 mg/kgBW and 1500 mg/kgBW, and the fourth group was the control group. Centella asiatica extract is administered orally via an intragastric feeding tube for two weeks, once daily At the end of the experimental period, rats were sacrificed by cervical decapitation. The left lung tissue was taken aseptically and cultured on Middlebrook 7H10. Result(s): The results showed that there was no bacterial growth on the culture media in the group that received Centella asiatica extract at a dose of 750 and 1500 mg/kg BW. Conclusion(s): The conclusion in this study, that Centella asiatica extract inhibit the growth of Mycobacterium tuberculosis at doses of 750 and 1500 mg/kg BW.

ABSTRACT

Background: Phytochemicals and their derivatives/analogues represent over 50% of the current medicines worldwide in clinical use. Despite a significant contribution to the total bioactive natural plant products, aquatic plants are underestimated, and several species are extinct and in the endangered list. Objective(s): The aim of this review article is to draw the attention of common people and scientists toward a few important contributions of the aquatic plants to natural product chemistry and drug discovery by highlighting the chemical and pharmaceutical aspects of the same. Method(s): The presented data were collected and selected from the literature obtained by an online search for the ethnomedicinal properties, biological activities and bioactive chemical constituents of aquatic plants using Google Scholar, PubMed and Scifinder chemical abstract service. Result(s): The selected literature data revealed that the extract and compounds isolated from several aquatic plants possess significant biological/pharmaceutical properties. For example, the alpha-asarone (24) and asiatic acid (33) isolated from Acorus calamus and Centella asiatica, respectively, exhibited significant neuroprotective effects in vitro and in vivo. The cripowellin A (59), cripowellin C (60), cripowellin B (61) and cripowellin D (62), isolated from Crinum erubescens, exhibited potent antiplasmodial and antiproliferative activities with half maximal inhibitory concentration (IC50) in nanomolar range (11-260 nM). Several other alkaloids from different Crinum species have also shown anticancer properties against different cancer cell lines with IC50 value <5 microM. Alkaloids and resin glycosides, isolated from different Ipomoea species, have displayed significant psychotropic, psychotomimetic, anticancer, and antibacterial activities with IC50 value <5 microM. Conclusion(s): The aquatic plants play a significant role in the discovery of bioactive natural products. Although several biological activities and bioactive compounds have been reported from these plants, further assessment and scientific validation of most of their traditional usages still need to be done. There are several other similar species that are underestimated and not much explored. Many aquatic plants, such as Ipomoea carnea Jacq., Juncus lomatophyllus Spreng., Commelina benghalensis Linn, Gunnera perpensa L., Scirpus maritimus L. and Mentha longifolia (L.) L., may be considered for further evaluation. In addition to these, one should not undermine the potential of Crinum macowanii for COVID-19 pathogenesis, as its chemical constituent lycorine has shown significant SARS-CoV-2 inhibitory potential (EC50, 0.3 muM;SI >129). Furthermore, most rural communities are still using the wetland resources for their cultural, medicinal, economic, domestic, and agricultural needs. Hence, the conservation of aquatic plants and wetlands is an issue of great concern.Copyright © 2023 Bentham Science Publishers.

ABSTRACT

Background and aim: Considering the coronavirus disease 2019 (COVID-19) pandemic and the expectation that dietary supplements (DS) boost the immune system of individuals, the aim of this research was to evaluate the use of DS and related factors by comparing periods before and during the pandemic. Method(s): A descriptive cross-sectional internet-based study was conducted with 1488 participants from the general public aged above 19 years. Result(s): The median age of participants was 33.0 (19-69) years and 88% of participants were women. A total of 48.9% of participants (50.2% of females, 39.9% of males) used DS before COVID-19, and DS use during COVID-19 was reported to be 57.9% (58.6% of females, 52.8% males). Independent variables of DS use before and during COVID-19 were sex, age, body mass index (BMI), education, income, vitamin/mineral deficiency (VMD), alcohol use, and medication use. Participants who had no VMD used more DS, mostly herbal supplements such as grape seed, gotu kola, ginseng, ginkgo biloba and green tea. Vitamin D and C were the most commonly-used DS among participants with vitamin/mineral deficiency, followed by zinc and multivitamins. The main reason for DS use (47.2%) during COVID-19 was to strengthen immunity. Conclusion(s): The current findings may help to understand the preferences of individuals about DS use during pandemics. Understanding factors associated with the use of DS and their claimed immune-boosting effects may support future studies aiming to provide accurate information and motivate individuals towards healthy use of supplements during pandemics.

ABSTRACT

Indonesia is a tropical country with mega-biodiversity. Several medicinal plants locally have been recognized for their anti-inflammatory properties and are traditionally used to help treat respiratory diseases. Chronic obstructive pulmonary disease (COPD) is one of the diseases known as the high cause of death globally, and one of the treatment efforts is by using anti-inflammatory drugs. In developing alternative remedies for COPD, this review summarizes the potential of Indonesian medicinal plants and their ingredients known to have an anti-inflammatory activity to develop alternative remedies for COPD. Primarily, we focus on the medicinal plants that have been scientifically proven to pose some biological activities, such as legetan warak (Adenostemma lavenia), celery (Apium graveolens), pegagan (Centella asiatica), kenikir (Cosmos caudatus), and kersen (Muntingia calabura). This review is expected to provide more information about Indonesian medicinal plants and their potencies to be developed as COPD herbal medicine and, further, as a treatment to help patients suffering from coronavirus disease (COVID-19).

ABSTRACT

Concerns have been raised about viral contamination, including in crops due to the recent coronavirus disease 2019 pandemic. Limited evidence is available to support the use of sanitizing agents for human coronavirus-contaminated medicinal plants. Thus, we aimed to investigate the persistence of infectious human coronavirus OC43 (HCoV-OC43) as a SARS-CoV-2 surrogate in storage conditions and the capability of neutral electrolyzed water (NEW) to inactivate coronavirus, including in fresh plants such as C. asiatica. The levels of infectious HCoV-OC43 and the triterpenoid content of C. asiatica were quantified using a plaque assay and high-performance liquid chromatography, respectively. The results showed that the persistence of HCoV-OC43 on C. asiatica leaves is identical to that on inert polystyrene. When covered and kept at room temperature with high humidity (>90% RH), HCoV-OC43 can be stable on C. asiatica leaves for at least 24 h. NEW with 197 ppm of available chlorine concentration (ACC) was effective in inactivating both infectious HCoV-OC43 and SARS-CoV-2 in suspension (≥3.68 and ≥4.34 log reduction, respectively), and inactivated dried HCoV-OC43 on the surfaces of C. asiatica leaves (≥2.31 log reduction). Soaking C. asiatica leaves for 5 min in NEW with 205 ppm of ACC or water resulted in significantly higher asiaticoside levels (37.82 ± 0.29 and 35.32 ± 0.74 mg/g dry weight, respectively), compared to the unsoaked group (29.96 ± 0.78 mg/g dry weight). These findings suggest that although coronavirus-contaminated C. asiatica leaves can pose a risk of transmission, NEW could be an option for inactivation.

ABSTRACT

Introduction: Muscle tightness is produced by a reduction in a muscle’s capacity to deform. As a result of prolong sitting pelvic position can be changed which can lead to iliopsoas tightness. During the COVID-19 pandemic, as a result of online classes, student’s hours of sitting have increased drastically. Aim: To compare iliopsoas muscle tightness in students who were engaged in prolonged sitting due to online classes with higher Body Mass Index (BMI) and students with normal BMI. Materials and Methods: This cross-sectional study was conducted in Department of Physiotherapy at Institute of Applied Medicine and Research, Ghaziabad, Uttar Pradesh, India, from April 2021 to January 2022 on 101 students. Height and weight of the subject were measured by the ruler and digital weighing machine respectively for the BMI calculation. Two groups were made, group with normal BMI students and group with High BMI students. Using modified Thomas test, iliopsoas muscle were measured for the flexibility. Independent sample t-test was used for statistical analysis. Results: Total 51 students were with normal BMI and 50 were with higher BMI were included in the study. The mean age of the subjects was 19.59 years including 59 females and 42 males. The significantly increased Modified Thomas Test (MTT) angle was found in students with higher BMI when compared to students with normal BMI for both right (p-value=0.003) and left side (p-value <0.001). Iliopsoas muscle tightness was present in more in higher BMI group as compared to normal BMI group. Conclusion: The study concluded that both the groups had the iliopsoas muscle tightness but the students with higher BMI had more muscle tightness.

ABSTRACT

Covid-19, the first case of which was reported in Wuhan (China) in December 2019 was found to be a strain of coronaviruses like SARS and MERS reported earlier. These viruses are positive strain RNA viruses composed of both structural as well as non-structural proteins. The enzyme RdRp (RNA dependent RNA polymerase) stands responsible for catalyzing the replication of this virus within the host cell. A disruption in the core catalytic subunit composed of nsp12, nsp7, and nsp8 may inhibit the replication of the same. Different drugs targeting different sites on the virus have been developed. In this context, some of the natural products of the plant Centella asiatica was lead for further drug development against the target proteins of RdRp protein (PDB ID: 6NUR) through molecular docking. These compounds are 2,3-dihydroxyurs-12-en-28-oic acid, corosolic acid and pomolic acid which are triterpenoids and have highest binding affinity against RdRp protein thereby arresting the viral replication. Several previous studies showed triterpenoids as pertinent mediators implicated in the in vitro immune response.
