Objective: To rationalize the folkloric use of hypoglycemic, antinociceptive and antioxidant potentials with phytochemical screening of methanolic bark extract of Crataeva nurvala (C. nurvala) in vivo and in vitro. Methods: The collected bark was dried and grinded. The coarse powder was soaked in 2000 mL of 90% methanol for several days then filtrated. At 40 °C the volume of crude methanolic extract (CME) was reduced by a vacuum rotary evaporator, then the aqueous methanol extract was separated into petroleum ether, carbon tetrachloride, and aqueous soluble fractions by Kupchan protocol. Then the extracts were subjected to evaluate in vivo analgesic, hypoglycemic activities in Swiss albino mice model and antioxidant in vitro. Results: In quantitative phytochemical analysis, total phenolic content was found maximum (235.94 mg of GAE/g) in aqueous soluble fraction;in case of antioxidant potentials, DPPH free radical scavenging assay showed IC50 value of 9.25 μg/mL exhibited by aqueous soluble fraction in comparison to ascorbic acid (8.27 μg/mL) as a reference standard. The CMEs potentially (P < 0.05) reduced the acetic acid-induced writhing and increased (P < 0.05;P< 0.01) latency period in the tail immersion method at a dose dependent manner. The CME significantly reduced blood sugar level of diabetic rat induced by alloxan monohydrate. Conclusions: This study was conducted to validate the extensive use of C. nurvala bark as folk medicine with antinociceptive, hypoglycemic and antioxidant effects. It can be concluded that the bark of C. nurvala possesses good antinociceptive, moderate hypoglycemic and antioxidant activities. However, further chemical and pharmacological revise are needed to elucidate the detail mode of action behind this and identify the responsible active principles.

Background: Coronavirus disease 2019, otherwise known as COVID-19, emerged in December of 2019. COVID-19 spreads through an airborne transmission route. Preventive measures were described to help decrease the spread of COVID-19 worldwide. There were a number of preventive measures that were globally adopted: social distance of at least 1 meter, mask wearing, washing hands for 20 seconds, and covering the mouth and nose if the person sneezes or coughs. Methods: A descriptive cross-sectional study among 362 students from the International University of Africa, Sudan, was carried out between August 2021 and September 2022. Statistical Package for Social Sciences version 26 was used for data analysis;frequency and percentage were used to describe the qualitative variables. A chi-square test was used for association analysis;a P-value ≤ 0.05 was considered statistically significant. Results: Among study participants, the females were 70.9%;most were 20 - 23 years old (73.6%). 54.2% were vaccinated against COVID-19;83.6% had good knowledge regarding the mode of transmission, and 76.1% stayed in during quarantine. 80.6% of participants understood social distancing correctly. 76.1% of males and 45.1% of females started or completed vaccination (P ≤ 0.05). 51.4% of males and 81.3% of females adhered to preventive measures (P ≤ 0.05). Conclusions: It is important to target health education campaigns and interventions to improve adherence to preventive measures among university students. Although the pandemic is coming to an end, a lesson should be learned from it, and future preparation should be employed.
