Abstract

Water pollution from settlements, agriculture, and industry is a significant issue, as it introduces pollutants like heavy metals into water bodies, harming both humans and aquatic ecosystems. Phytoremediation is a cost-effective, eco-friendly technology for reducing heavy metals in water bodies. This study aimed to assess Azolla filiculoides plants' ability to absorb heavy metals nickel and mercury. The plants were grown in a hydroponic solution contaminated with 0.25 ppm of nickel and 0.5 ppm of mercury. The growth of the plants was measured based on their wet and dry weight, and the nickel and mercury content in the plant tissue was analyzed using Atomic Absorption Spectrophotometry (AAS). The study found that the growth of A. filiculoides plants was unaffected by the concentration of either nickel or mercury. The amount of nickel absorbed by the plants was 0 µg/g plant dry weight, while for mercury, it was 1654.82 µg/g. Based on the results, A. filiculoides plant is more promising for use as a phytoremediation agent for water bodies contaminated with mercury heavy metals rather than nickel heavy metals.

Abstract

Sarcotheca celebica is an endemic Sulawesi plant capable of growing in ultramafic and calcareous soils. The anatomical structure of its vegetative organs plays a role in adaptation to extreme environments. This study aimed to compare the anatomy of leaves, stems and roots of S. celebica in both soil types. Microscopic preparations of leaves, stems and roots were made with the Free Hand Section method, documented using Optilab Viewer 2.2, and measured with Image Raster 3. Statistical analysis was conducted with the T-test. The results showed anatomical variations in response to soil conditions. S. celebica plants in calcareous soil had longer and wider stomata, but with lower density than those in ultramafic soils. In addition, leaf and cuticle thickness were higher in S. celebica plants on calcareous soils. However, the peridemis/floem ratio in stems and peridermis/endodermis in roots did not show significant differences. Overall, S. celebica leaves were more responsive to soil differences than stems and roots. This study is important for understanding the mechanisms of plant adaptation to extreme soil conditions and the implications for the sustainability of the species in its natural habitat.

Abstract

Colorectal cancer remains one of the leading causes of cancer-related deaths after lung cancer, highlighting the urgent need for more effective therapies with minimal side effects. Begonia medicinalis has been reported to have potential anticancer properties. This study aimed to evaluate the anticancer activity of Begonia medicinalis extract by assessing neutrophil concentration in a 7,12-dimethylbenz[a]anthracene (DMBA)-induced colorectal cancer rat model. The research employed a laboratory-based experimental approach with a post-test-only group design, comprising five groups with five replications each: treatment group I receiving a 25 mg/kg body weight, treatment group II receiving a 50 mg/kg body weight, treatment group III receiving a 100 mg/kg body weight, an normal group that was not DMBA-induced and did not receive therapy, and a negative control group that was DMBA-induced but did not receive therapy. The results of this study demonstrate that Begonia medicinalis extract effectively suppresses neutrophil concentration in a DMBA-induced colorectal cancer rat model. Treatment with 50 mg/kg body weight and 100 mg/kg body weight doses successfully reduced neutrophil cell levels in the experimental subjects, with the best results seen at the 100 mg/kg body weight dosage. This study provides new insights into the effects of plant-based therapies, Begonia medicinalis extract, in modulating the immune system by suppressing neutrophil concentration in a colorectal cancer rat model.
