Background: Diabetes is a disease that affects people worldwide, including in Indonesia. The prevalence of diabetes in Indonesia is increasing from year to year. One of the most devastating complications of diabetes mellitus is diabetic ulcers, which is a limb-threatening complication. Over the past few decades, ozone generated using plasma medical technology has been investigated as an agent that helps wound healing. This study aims to evaluate the effects of topical ozonated virgin coconut oil (VCO) in a diabetic wound mouse model. Methods: This study was an experimental study with a post-test control design. An ulcer wound model was made in 50 diabetic male Wistar mice, divided into five groups, and a control group of 10 non-diabetic mice. The control groups were given conventional therapy only and the treatment groups were also given topical ozonated VCO with different flow durations (0 min, 90 min, 7 h, 14 h). Macroscopic appearance and wound contraction were observed. HSP90β, VEGF-A, EGF, bFGF and CD34 levels were measured from the immunostained slices of wound margins. Results: The reduction of wound length was proportionally related to the duration of ozone flow. Ozonated VCO with a longer duration of ozone flow healed the wound more quickly and had the shortest wound length. VCO with ozone flow for 14 hours (16837.10 µm) had the biggest reduction in wound length compared to other groups. The wounds treated with ozonated VCO showed an increase in HSP90β, VEGF-A, EGF, bFGF and CD34 levels that correlated to improved wound healing. A longer period of treatment resulted in higher levels of wound healing biomarkers compared to shorter therapeutic durations. Conclusions: Topical ozonated VCO improved the wound healing process in a diabetic ulcer mouse model by improving macroscopic wound appearance and increasing levels of wound healing biomarkers.
Xeroderma pigmentosum (XP) is a rare autosomal recessive disease characterized by hypersensitivity of the skin to ultraviolet radiation and other carcinogenic agents. This ailment is characterized by increased photosensitivity, skin xerosis, early skin aging, actinic keratosis, erythematous lesions, and hyperpigmentation macules. In this serial case report, we presented four cases with XP from two families in Indonesia. Both families were referred from rural referral health centers, and each family has two affected siblings. They had freckle-like pigmentation on the face, trunk, and extremities, which progressed since childhood. One patient of family 2 died because of an infectious disease. Histopathological examination using cytokeratine (CK), CD10, and Ber-EP4 staining from available tissue biopsy of one affected case of family 1 identified basal cell carcinoma (BCC) on the cheek and melanoma on the right eye. Mutation analysis found ERCC2, c2047C>T and XPC, c1941T>A in the first and second families, respectively. We suppose that this is the first case report of XP in Indonesia that incorporates clinical examination, genetic analysis, and extensive histopathological examination, including immunohistochemistry staining, and a novel pathogenic variant of XPC was found in the second family.
Purpose One of the most serious and devastating complications of diabetes mellitus is diabetic ulcers. They are difficult to treat and often result in limb loss. Topical sucralfate and platelet-rich plasma have the potential to improve the healing outcomes of chronic ulcers, including diabetic ulcers. This research aims to determine the effectiveness of sucralfate and platelet-rich plasma therapy for the improvement of diabetic ulcer wound healing. Patients and Methods Ninety Wistar rats were used in this study and were classified into five groups. Four of the five groups were diabetic induced and were treated with topical sucralfate only, platelet-rich plasma only, combination of topical sucralfate and platelet-rich plasma, and diabetic control group which received standard therapy only. The non-diabetic control group did not receive any therapy. We observed macrophage amount, platelet-derived growth factor, vascular endothelial growth factor, and hypoxia-inducible factor as a biomarker. Rats were terminated after 7th and 14th days and were subjected to immunohistochemistry staining and examination. Results We found that topical sucralfate and platelet-rich plasma increase macrophage levels, vascular endothelial growth factor expression and platelet-derived growth factor expression in diabetic wound cells. We also found a reduction in hypoxia inducible factor-1α expression. Combination of topical sucralfate and platelet-rich plasma for 14 days gave the most significant improvement in terms of wound healing compared to topical sucralfate or platelet-rich plasma alone. Conclusion The combination of topical sucralfate and platelet-rich plasma therapy results in the best improvement in diabetic ulcer wound healing compared to sucralfate or platelet-rich plasma monotherapy or conventional wound healing therapy.
Phycocyanin from Spirulina platensis extract has anticancer activity against various types of cancer cell cultures. However study about its effect on colon cancer cell lines, especially the WiDr, has not been reported before. This study aimed to reveal the anticancer activity of phycocyanin from Spirulina platensis extract on WiDr cells. The research was an in vitro experimental study, with the investigation on cytotoxicity also antiproliferation as the anticancer parameters. Both cytotoxicity and antiproliferation test was conducted through MTT assay to observe the visualization and inhibition of proliferation of different concentrations of phycocyanin in several incubation times on the WiDr colon cancer cell line. The obtained data were then processed statistically with the Two Way ANOVA test at a significance value of p <0.05 and followed with the Post Hoc test since there were significant differences. Based on the results, it could be postulated that phycocyanin extracted from freshwater Spirulina platensis was classified as non-toxic (IC50 of 855 µg/ml). Consequently, it is less potential to be used as the treatment for colon cancer. However, phycocyanin could inhibit the proliferation of the WiDr cell for approximately 47.4%, specifically at the concentration of 1710 µg/ml for 72 hours. It could be concluded that freshwater phycocyanin is less effective as an anticancer substance. The benefit of this study is to provide the new scientific evidence of the contrary results of freshwater phycocyanin activity from Spirulina platensis as an anticancer agent of colon cancer.
