Eye Pain

Mekai leaves (Pycnarrhena cauliflora Diels.) (P. cauliflora). Are known to contain flavonoid compounds, tannins and phenolics that act as antibacterial agents and are used in the treatment of eye pain. Staphylococcus aureus (S. aureus) is one of the examples of bacterial diseases of eye pain and also a major cause of many infections in communities and health facilities with cases of resistance to various antimicrobial agents. The purpose of this study was to prove the antibacterial activity of mekai leaves ethanol extract against S. aureus bacteria. This research is an experimental research. The stages of this research began by extracting mekai leaves using maceration method with 96% ethanol solvent. Antibacterial activity was tested by the disc method (Kirby-Bauer) using ethanol extract concentrations of mekai leaves (EPC) 20%, 30%, 40%, 50%, 60%, 70%, and 80%, positive control using 25 μg amoxicillin and negative control using DMSO 10%. The measurement results of inhibition zones of mekai leaf ethanol extract 20%, 30%, 40%, 50%, 60%, 70% and 80% respectively were 8.32 mm, 8.32 mm, 8.32 mm, 8.67 mm, 9.00 mm, 8.67 mm, and 8.33 mm. While the positive control measurement of 25 μg amoxicillin against S. aureus is 28.67 mm and the measurement of 10% negative DMSO control does not produce inhibitory zones, so it can be concluded that the ethanol extract of mekai leaves has antibacterial activity, but the area of ​​inhibition zone produced is smaller than amoxicillin 25 µg. The results of statistical tests using Mann Whitney between negative controls with all EPC concentrations obtained significant differences with p values ​​<0.05, it can be concluded that there is antibacterial activity produced at all EPC concentrations.

Acne is associated with hyperkeratosis, elevated levels of skin sebum and growth of Propionibacterium acnes (P. acnes) and Staphylococcus aureus (S. aureus). Furthermore, P. acnes promotes inflammation by inducing IL-6 production and oxidative stress. The aim of this study was to assess the antioxidant, anti-inflammatory and antibacterial potential of a hop-CO2-extract with 50% humulone and lupulone. The susceptibility of P. acnes and S. aureus to the hop extract was tested by using the broth microdilution technique. The minimal inhibitory concentrations (MIC) for P. acnes and S. aureus were 3.1 and 9.4 µg/mL, respectively. In addition, the hop extract showed an antioxidative effect with a half maximal inhibitory concentration (IC50) of 29.43 µg/mL as well as additional anti-inflammatory effects by reducing the IL-6 expression (IC50: 0.8 µg/mL). In addition, a gel formulation with 0.3% hop extract (w/w) had antibacterial activity against P. acnes and S. aureus (inhibition zone value: 5.5 mm and 3 mm, respectively) which was significantly superior to the placebo gel. The positive control (a gel with the antibiotic clindamycin) showed an inhibition zone of 9 mm. Due to its antioxidant, anti-inflammatory and antibacterial effects hop extract might be a treatment option for acne-prone skin.

The most common skin disorder is acne (Acne vulgaris) which is a chronic inflammatory disease that occurs in the pilosebaceous unit. Infection can be caused by Propionibacterium acnes and Staphylococcus aureus. Moringa leaves are known to inhibit acne growth. Piper crocatum leaves are also thought to have antibacterial activity. The study aims to determine the effect of the combination of the two extracts in inhibiting the growth of acne-causing bacteria, also tested the gel formula to meet physical and chemical parameters as well as stability to temperature and storage, also to test the acute dermal irritation against rabbit. Each extract with a concentration of 0.3%; 0.6%; 1.25%; 2.5%; 5%; 10%; 20%, incubated then measured the inhibition zone, then determined the minimum inhibition zone concentration of the two extracts to determine the lowest levels of the extracts which still gave antibacterial activity against the tested bacteria by the well diffusion method. The extract combination was formulated in a gel preparation with the excipients Carbopol 940, PG, Phenoxyethanol, TEA, CMC, and Aquadest. Antibacterial activity test for gel preparations used the well method with positive control Medi-Klin® gel. Then the formula evaluation includes physical, chemical, and microbiological evaluations. The results showed that the combination gel form had activity against P. acne and S. aureus at concentrations of 2.5% : 2.5%. The combination gel preparation of the two extracts also has synergistic effect in inhibiting acne bacteria. The formula can meet physical and chemical parameters and is stable to temperature and storage.

This work was designed to evaluate the antibacterial activity of one novel leather material treated with bactericides. The growth of bacteria species such as colibacillus and staphylococcus aureus were measured by the diameter of inhibition zone. The results showed that glutaraldehyde exhibits an antibacterial activity against colibacillus and staphylococcus aureus. Besides, it also is testified that 2-Octyl-4-isothiazolin-3-one was an excellent bactericidal agents to staphylococcus aureus, instead of colibacillus. The concentrations of tea saponin and sodium above 0.05mg/L, the growth of bacteria was restrained. In addition, compared with single of bactericidal agents, the mixture of two bactericidal agents showed much better antibacterial activity. Among these antimicrobial agents, the mxture of 2-Octyl-4-isothiazolin-3-one and glutaraldehyde were of great potential in application.
