Hemostatic Effect

Hemorrhage occurs in most of the dental care. Untreated hemorrhage could cause excessive blood loss, hypotension, and cyanosis. A Natural resource that reported has an hemostatic effect is ethanol extract of betel leaves (Piper betel, Linn).The aim of this study is to find the minimum concentration of ethanol extract of betel leaves which capable of shortening the bleeding time in mice. The experimental study used pretest-posttest with control group design was conducted on 35 mice that divided into 7 group which are negative control, positive control (feracrylum 1%), the ethanol extract of betel leaves 1%, 5%, 10%, 15%, and 20%. All mice were injected heparin intravenously. Mice’s tail was cut at diameter 3 mm and pretest bleeding time was counted. Mice’s tail was recut at diameter 4 mm, given treatment for 5 seconds and posttest bleeding time was counted. Results of paired t-test showed that reduction of bleeding time between pretest and posttest was significant (p<0,050). The enhancement of ethanol extract of betel leaves concentration leads to better hemostatic effect. Results of ANOVA test showed that comparison of posttest bleeding time among groups was significant (p<0,050). The minimum concentration of ethanol extract of betel leaves which capable of shortening the bleeding time in mice is 5%.

Abstract: One of the treatment options of periodontal abscess caused by Fusobacterium nucleatum is administration of antibiotics. However, long-term antibiotics consumption can cause negative side effects. Therefore, alternative treatments that have low side effects and easy to be obtained are needed. Nike fish (Awaous melanocephalus) is one of the endemic fish of North Sulawesi province which has antibacterial properties. This study was aimed to evaluate the inhibition effect of nike fish extract on the growth of Fusobacterium nucleatum. This was a true experimental study with a posttest only control group design. We used modified Kirby-Bauer method with filter papers. Ciprofloxacin was used as the positive control and aquadest as the negative control. Extract of nike fish and stock of pure bacteria Fusobacterium nucleatum were prepared. The results showed that the average diameters of the inhibition zones formed in the nike fish extract after three repetitions, were as follows: for extract concentration of 12.5% was 2.91 mm; 25% was 4.16 mm; 50% was 8.41 mm; and 100% was 9.58 mm. In conclusion, nike fish extract (Awaous melanocephalus) at concentrations of 50% and 100% had a weak inhibitory effect (Himedia category) on the growth of Fusobacterium nucleatum meanwhile at concentrations of 12.5% and 25% there was no activity of zone of inhibition.Keywords: extract of nike fish (Awaous melanocephalus); Fusobacterium nucleatum; inhibitory effect Abstrak: Salah satu opsi pengobatan abses periodontal yang disebabkan oleh bakteri Fusobacterium nucleatum yaitu dengan penggunaan antibiotik namun mengonsumsi antibiotik jangka panjang dapat menimbulkan efek samping negatif.

ABSTRACTGreen betel leaves are one of the native plants in Indonesia which are widespread in Manado, North Sulawesi. In green betel leaves plants, there are tannin compounds that can inhibit enzymes and interfere with the digestive metabolic processes of worms which can cause the death of worms. This study aims to determine the effect of green betel leaves ethanol extract on Ascaris lumbricoides worms. This research is a laboratory experiment with The post-test only with controlled group design. The tests used the betel leaves ethanol extract with concentrations of 5%, 10%, and 15% respectively. Worms was observed for 12 hours with intervals of 3 hours. The number of worm deaths was recorded every 3 hours and further, it was analysed with using the Kruskal Wallis test and it was continued with using the Mann Whitney test. Result showed that extract at concentration of 5% the number of worm deaths was 4 worms, a concentration of 10% was 7 worms, and at a concentration of 15% 9 worms. The statistical results showed that there was no significant difference between the number of worm deaths in the treatment group and negative control at p <0.05. The concentrations of 10 and 15 showed no significant difference with the positive control. It can be concluded that concentrations of 10% and 15% have the same anthelmintic activity but the best concentration is at a concentration of 10%. Keywords: Anthelmintic, Piper betle L., Ascaris lumbricoides   ABSTRAKDaun sirih hijau merupakan salah satu tanaman asli di Indonesia yang tersebar luas di kota Manado, Sulawesi Utara.

Abstract: Mouthwash could inhibit the growth of Staphylococcus aureus bacteria in the oral cavity. Albeit, the most widely used today is mouthwash containing clorhexidine that has side effects in prolonged use. Therefore, it is necessary to find new agents as an alternative antibacterial, especially against Staphylococcus aureus. Squid ink is one of the best known seafood used as alternative medicine which has a wide range of therapeutic applications. This study was aimed to evaluate the inhibitory effect of squid ink extract (Loligo sp) on the growth of S. aureus. This was a true experimental study with a post test only control group design. We used modified Kirby-Bauer method using filter papers. Ciprofloxacin antibacterial was used as the positive control and aquadest as the negative control. Extract of squid ink (Loligo sp) and stock of pure bacteria S. aureus bacteria were prepared. The results showed that mean of zone of inhibition of the squid ink extract (Loligo sp) was 11.22 mm which was less than the zone of inhibition of ciprofloxacin. In conclusion, the squid ink extract (Loligo sp) had a moderate inhibitory effect (Himedia category) on the growth of Staphylococcus aureus.Keywords: extract of squid ink (Loligo sp), Staphylococcus aureus, inhibitory effectAbstrak: Salah satu cara penanganan bakteri Staphylococcus aureus dalam rongga mulut ialah dengan menggunakan obat kumur.
