But, thereis a lack of understanding about mechanism that control the growth andproliferation of fibroblast. Immunohistochemistry TE-7 is one of method couldbe used to stain fibroblast in paraffin-embedded tissue sample. Objectives: Toanalyzed the role of immunohistochemistry in wound healing of models ulcerpost-exposure of identified roselle calyx. Method: Twelve paraffin embeddedtissue of models ulcer were processing and staining with immunohistochemistryTE-7. Microscopic slide were observed and scored. Result: On day 1st and 3rd,saline, TA and roselle group showed scored 1. On day 7th, saline showed score 2;TA showed score 3 and roselle showed score 1. On day 14th, saline and roselleshowed score 1; TA showed score 2. Conclusion: Immunohistochemicalexamination antibody TE-7 could be used to identify fibroblast in wound healingof model ulcers."

"Keloid merupakan jaringan tumor jinak yang tumbuh akibat proses penyembuhan luka menyimpang. Keloid dapat menimbulkan masalah kosmetik maupun gangguan fungsi tubuh, terutama bila keloid timbul pada daerah persendian. Patogenesisnya belum sepenuhnya diketahui, namun fibroblas teraktivasi terlibat dalam dekomposisi kolagen berlebih pada matriks ekstraseluler. Di sisi lain, fibroblas mensintesis sitoglobin. Ekspresi sitoglobin berlebih dapat menekan proliferasi fibroblas. Berbagai terapi keloid hingga saat ini belum optimal karena masih sering terjadi rekurensi. Penelitian ini bertujuan untuk mengeksplorasi pengaruh ekstrak etanol gambir (EG) terhadap viabilitas fibroblas keloid serta ekspresi sitoglobin, elastin dan desmosin. Penelitian dilakukan dengan isolasi dan kultur primer fibroblas keloid serta dianalisis nilai IC50 EG nya, serta ekspresi sitoglobin, elastin dan desmosin. Didapatkan hasil bahwa EG dapat menurunkan viabilitas fibroblas keloid dan signifikan meningkatkan ekspresi sitoglobin, elastin dan desmosin. Dengan demikian, EG berpotensi sebagai antikeloid.

Keloids are benign tumor that grow as a result of aberrant wound healing processes. Keloid can cause cosmetic problems and impaired body function, especially if they occur on joint area. The pathogenesis isn’t fully understood, but activated fibroblasts are involved in the decomposition of excess collagen in the extracellular matrix. In contrast, fibroblasts synthesize cytoglobin. Various keloid therapies until now haven’t been optimal due to numerous recurrences. This study aims to explore the effect of ethanolic extract of gambir (EG) on the viability of keloid fibroblasts and the expression of cytoglobin, elastin, and desmosine. The experiment done by isolation and primary culture of keloid fibroblasts and analyzed its IC50 EG value, and cytoglobin, elastin, and desmosine. The result showed that EG can decrease in keloid fibroblast viability and the expression of cytoglobin, elastin, and desmosine. Thus, EG has potential as an anti-keloid."
