Abstract

Objective: To observe platelet functions during the 3 days of platelet storage and to evaluate the effect of storage temperature towards platelet aggregation response. Methods: Two conditions of platelet storage were used in this study: at room temperature and in a cold condition at 4 °C to observe the temperature effect on platelet aggregation. The aggregation test was performed using a 96-wells plate platelet aggregation method. Results: At room temperature on day 1, the response of platelet aggregation reduced to 34.9±10.6%, which was less than half of the aggregation of fresh platelet (100%). The aggregation on day 2 reduced modestly (26.8±4.2%), in comparison with that seen on the first day. On day 3, platelet aggregation deteriorated significantly (6±1.2%), which was comparable to the control group without the presence of platelet agonist (6.1±1.4%). When platelets are stored at 4 °C, the aggregation response to ADP stimulation was slightly different to that shown by platelets stored at room temperature (22 °C). At the 4 °C, the aggregation response was 68.11±34.2%, 57.1±21.4%, and 5.9±2.6% at day 1, day 2, and day 3, respectively. The result showed that storing the blood at 4 ˚C or room temperature was not able to preserve platelet function, as the deterioration of platelet aggregation response over time was still taking place. Although was not statistically significant, our result indicated that cold storage reduced platelet responsiveness toward ADP activation. Conclusions: This current study provides evidence of the deterioration of platelet function during first 3 days of platelet storage. Moreover, we found that storing platelets in 4 °C showed no significant benefit in preserving the ADP-induced platelet aggregation capacity compared to that stored in 22 °C.

Abstract

Medicinal plants have been used worldwide as supportive therapy in reducing symptoms of various diseases, including COVID-19 symptoms. The objective of this study was to investigate the use of medicinal plants and herbal products in respondents who experienced symptoms of COVID-19 in Aceh, Indonesia. A cross-sectional study was conducted, involving 384 respondents from the age group over 18 years old residing in Aceh Province, Indonesia. Data was collected via an online questionnaire consisting of 4 structured questions to assess the types and names of medicinal plants, the time of use, and the purpose of using medicinal plants. The results showed that nearly half of the study population (181 respondents) consumed medicinal plants and commercial products, mainly for the reason to enhance their immunity (49.7%), followed by to overcome the COVID-19 symptoms (26.7%). Amongst all medicinal remedies mentioned in this study, Ginger (Zingiber officinale) and turmeric (Curcuma longa) are the most widely used, which were consumed by 65.5% of medicinal plant and herbal products users. The other medicinal plant chosen by the study population were lemon (Citrus lemon), Java Ginger/temulawak (Curcuma zanthorrhiza), and Habbatus sauda (Nigella sativa). Although the majority of the respondents had used the herbal remedies prior contracting COVID-19 symptoms (45.5%), a third of the respondents consumed traditional medicine during the symptomatic period only (less than two weeks). This study has demonstrated the characteristics of the consumption of medicinal plants and their commercial products in Aceh, during the occurrence of COVID-19 symptoms in the study population.
