Tooth extraction is a process of removing teeth from the alveolar bone. In wound healing, fibroblast are very important cells. The main purpose of this study was to determine the effect of mobe leaf 1% and 3% extract gel (Artocarpus lakoocha) on fibroblast proliferation in post extraction tooth socket wound healing. This research used 16 samples of wistar rats, divided into 4 groups, a positive control group, a negative control group and a 1% and 3% mobe leaf extract gel group. The left mandibular incisors were extracted, then 1% and 3% gels of mobe leaf extract were applied on day 1 to day 7. Data analysis was calculated using the Kruskal-Wallis test on clinical data and one way ANOVA test for microscopic. The result of the socket wound healing activity test for a good concentration of mobe leaf extract gel was 3%. This research shows significant resultith p-value of 0.018 (< 0.05) on the closure of the socket wound clinically which means the closure of the wound accelerates because of the mobe leaf 3% extract gel treatment. The distance of fibroblast on microscopically shows significant resultith a p-value of 0.002 (< 0.05), which means that there was an enlargement of the distance fibroblast at the socket wound closure with application of mobe leaf 3% extract gel. From the results of the study it can be concluded that mobe leaf 3% extract gel has the best ability to show acceleration the closure of the socket wound either clinically or microscopically.

Ascariasis is a neglected tropical disease prevalent in areas with poor hygiene and low standard of living in tropical countries. Hyptis suaveolens is been used traditionally around the world for various ailments. The aim of the study was to evaluate the anthelminthic activity of the methanolic leaf extract of the plant on the three life cycle stages of Ascaris suum synonymous to Ascaris lumbricoides. The phytochemical analysis of the extract was evaluated. The in-vitro anthelminthic activity of the methanolic leaf extract of Hyptis suaveolens on the egg hatchability and larva inhibition of Ascaris suum were assessed using Bizimenyara inhibition method, where 100 eggs were counted and incubated in 5 different plate-wells containing positive control, negative control and 3 concentrations (50, 70 and 100 mg/ml) of extract. The plate wells were brought out after incubation and content examined under the microscope. The effect of the methanolic leaf extract and pyrantel pamoate on cuticle peeling, motility and mortality were evaluated using adult worms. The egg hatchability and larval development after incubation for 48 h and 21 days significantly (p<0.05 for both) inhibited with 98% unhatched eggs and 95% undeveloped larva of A. suum respectively. There was significant (p<0.05) visible peeling of cuticles, reduced motility and mortality of the adult worms after 30, 12 and 80 minutes respectively. It can be concluded that H. suaveolens has anthelminthic activity on A. suum which may be attributed to some of the phytochemical constituents.
