Abstract

There is a tendency back to nature treatment in Indonesian community because modern/synthetic medicines is expensive and have a various alarming side effects. That is why natural products medicine becomes more popular, aside from mass media promotions. Researches on natural products such as herbal medicine increases along with the desire to get phytofarmaca that can compete with modern medicines. The aims of this literature review are to discuss and provides information on pharmaceutical standardization of natural products toward phytopharmaca for developing Indonesian traditional medicine. Pharmaceutical standardization will strengthen the basic of pharmaceutical science in producing safe, efficacy, and qualify traditional medicine products. The pharmaceutical standardization consists of standardizing simplicial quality, safety, efficacy, and stable formulation of medicines for use in health services.

Abstract

Chitosan is a derivative of chitin which has potential for use in bone regeneration and has been reported can stimulate bone formation. Oxidative stress as one cause of bone damage, was found increased in osteoporosis, periodontitis and arthritis. One of the species oxygen reactive (ROS), hydrogen peroxide, has been reported can inhibit osteoblast proliferation. This study was aimed to investigate the effect of various chitosan concentrations on protein content in the culture medium of human osteoblast-like cell line, MG 63, which was exposed to hydrogen peroxide. MG 63 cells were exposed to various chitosan concentrations (% w/v) 0.1, 0.2, 0.4, and 1.6%. Culture cells without chitosan were used as a control. Cells were growth with α-MEM medium (37ºC, 5% CO2) until they became confluent, then they were exposed to hydrogen peroxide for 4 hours. The protein content in the culture medium was measured by using Bradford protein assay at 655 nm wavelength. The result showed that hydrogen peroxide decreased protein concentration in the medium culture compared with group without hydrogen peroxide. Treatment group with chitosan concentration 0.4% and 1.6% exhibited a significant increasing of protein concentration in osteoblast culture medium compared with control. In conclusion, in osteoblast culture medium chitosan can inhibit the decreasing of total protein concentration which was caused by oxidative stress.

Abstract

Background: Ulceration caused by chemical agents used in dental practice for in-office or home-used is a common event, resulting in discomfort and pain. Treatments for such conditions are still being developed, requiring extensive experiments both in vitro and in vivo studies. At present, a standardized experimental mouse model for mucosal ulceration caused by a chemical inducer to study the pathogenesis of ulceration and to develop medications for treatment of ulceration is still not available. The aim of this study was to create a chemically induced model of ulceration of the buccal mucosa of mice. Methods: An in vivo study model of ulceration using a total of 9 mice (Swiss Webster) was performed. All mice received 70% acetic acid application on the left buccal mucosa, while the right buccal mucosa received only saline. Clinical and histological observations of ulcer formation and healing were performed, including the presence of redness and swelling, ulcer diameter, bodyweight as well as epithelial disintegration, dilation of blood vessels, and infiltration of inflammatory cells. Results: Buccal mucosa application of 70% acetic acid generated ulcers on day 2, reached its peak on day 3 and recovered by day 14. The histological features of inflammation were also seen in the ulcer model, and the degree of inflammation was consistent with the day of ulcers. Conclusion: Chemical trauma by the administration of 70% acetic acid effectively induce ulceration on buccal mucosa in mice, and this method can be considered as a novel, reproducible, and clinically relevant model to study pathogenesis and therapeutic approach for treating oral mucosal ulceration.
