Introduction: Neutrophils are cells which played an initial role in the inflammation area and can be induced by lipopolysaccharide (LPS). Activated neutrophils will secrete the COX-2 enzyme which is involved in arachidonic acid synthesis to produce inflammatory mediators. However, excessive inflammation can cause tissue destruction; thus, the body needs anti-inflammation agents. Cassava leaf contains biochemical component which has an anti-inflammation effect. This study was aimed to determine the expression of COX-2 in neutrophils administered with cassava leaf extract and the LPS of E. coli. Methods: This study was experimental laboratories (in vitro study) using human neutrophil cells culture. The samples of this study were divided into 4 groups, administered with 12.5% cassava leaf extract (T1); 25% cassava leaf extract (T2); control group which contained only neutrophils cells (C1); and control group contained neutrophils and LPS (C2). Human neutrophil cells culture was incubated in the 12.5% and 25% cassava leaf extract before exposed with the LPS of E. coli. COX-2 expression was observed with immunochemistry methods. Results: The COX-2 expression in the 12.5% cassava leaf extract group was significantly higher than the 25% cassava leaf extract group (p < 0.05). Conclusion: Cassava leaf extract can inhibit the COX-2 expression and can be used as an alternative anti-inflammation agent.Keywords: Anti-inflammation, cassava leaf extract, COX-2 expression, neutrophils.

Pendahuluan: Disfungsi ovarium merupakan kondisi yang menimbulkan defisiensi hormon estrogen dan progesteron. Penurunan hormonal ini menyebabkan peningkatan produksi tumor necrosis factor (TNF) yang dapat memicu peningkatan produksi matriks metalloproteinase-8 (MMP-8). Periodontitis yang disebabkan oleh bakteri gram negatif akan memicu makrofag melepaskan TNF-α yang berkontribusi dalam pembentukan MMP-8. MMP-8 ini berperan dalam degradasi kolagen jaringan ikat gingiva. Meningkatnya MMP-8 dapat menyebabkan terjadinya periodontitis. Gejala periodontitis karena disfungsi ovarium dan induksi bakteri ini dapat diperlambat dengan bahan alam, yaitu daun singkong. Tujuan penelitian ini adalah untuk menganalisis potensi ekstrak daun singkong (Manihot esculenta Crantz) terhadap ekspresi MMP-8 fibroblas pada model tikus disfungsi ovarium dan periodontitis. Metode: Penelitian ini merupakan penelitian eksperimental laboratoris dengan post-test only control group design. Sampel yang digunakan adalah tikus Sprague-Dawley betina yang dibagi dalam 5 kelompok yaitu (1) kelompok kontrol (K), (2) Kelompok yang diinduksi bakteri Porphyromonas gingivalis dan diberi aquades, (3) Kelompok yang diinduksi bakteri Porphyromonas gingivalis dan diberi ekstrak daun singkong, (4) Kelompok yang diberi perlakuan ovariektomi dan diberi aquades, (5) Kelompok yang dilakukan ovariektomi dan diberi ekstrak daun singkong. Pengambilan jaringan gingiva setelah tahap euthanasia dilakukan untuk pembuatan preparat histopatologi dengan pewarnaan imunohistokimia. Pengamatan dan penghitungan ekspresi MMP-8 dilakukan dengan menggunakan software ImageJ dan Immunoratio. Hasil: Hasil analisis data one-way ANOVA, ekspresi MMP-8 fibroblas gingiva menunjukkan perbedaan yang signifikan (p=0,000). Hal ini menunjukkan bahwa ekstrak daun singkong dapat menurunkan ekspresi MMP-8 fibroblas gingiva tikus yang mengalami disfungsi ovarium dan periodontitis diinduksi P. gingivalis. Simpulan: Ekstrak daun singkong (Manihot esculenta Crantz) dapat menurunkan ekspresi MMP-8 sel fibroblas gingiva pada model tikus disfungsi ovarium dan periodontitis.Kata kunci: Disfungsi ovarium, periodontitis, ekspresi MMP-8, ekstrak daun singkong. ABSTRACTIntroduction: Ovarian dysfunction is a condition that causes estrogen and progesterone deficiency. This hormonal decrease causes an increase in the production of Tumour Necrosis Factor (TNF), which can trigger an increase in the production of matrix metalloproteinase-8 (MMP-8). Periodontitis caused by gram-negative bacteria will trigger macrophages to release TNF-α, which contributes to the formation of MMP-8. MMP-8 plays a role in collagen degradation of the gingival connective tissue. An increase in MMP-8 can cause periodontitis. Periodontitis symptoms due to ovarian dysfunction and bacterial induction can be slowed down by natural ingredients, such as cassava leaf. The purpose of this study was to analyse the potential of cassava leaf extract (Manihot esculenta Crantz) on MMP-8 expression of gingival fibroblast in rats model with ovarian dysfunction and periodontitis. Methods: This study was an experimental laboratory with post-test only control group design. The samples were female Sprague-Dawley rats divided into five groups: (1) control group (K); (2) Porphyromonas gingivalis induced group and given aquadest; (3) Porphyromonas gingivalis induced and given cassava leaf extract; (4) Group with ovariectomy treatment and given aquadest; (5) Group with ovariectomy treatment and given cassava leaf extract. Gingival tissue retrieval after the euthanasia was carried out for the histopathology preparations by immunohistochemical staining. Observation and calculation of MMP-8 expressions were performed using ImageJ and Immunoratio software. Results: The results of the one-way ANOVA analysis of MMP-8 expression of gingival fibroblasts showed a significant difference (p = 0.000); thus cassava leaf extract reduce the MMP-8 expression of gingival fibroblasts of rats with ovarian dysfunction and P. gingivalis induced periodontitis. Conclusion: Cassava (Manihot esculenta Crantz) leaf extract can reduce the MMP-8 expression of gingival fibroblast cells in rats’ model with ovarian dysfunction and periodontitis.Keywords: Ovarian dysfunction, periodontitis, MMP-8 expression, cassava leaf extract.

Background: Bacteria playing a role in periodontitis are Gram-negative anaerobic bacteria that can release endotoxin or lipopolysaccharide (LPS). LPS acts as a stimulus to a variety of host cells that can stimulate expression of pro-inflammatory cytokines in periodontal disease, such as

Background: Periodontal disease is a common and widespread disease in the community. Gram negative bacteria have a role in periodontitis. These bacteria secrete a variety of products such as endotoxin lipopolysaccharide (LPS), which causes the occurrence of inflammation or infection. The body defense responses are neutrophils and mononuclear cells (monocytes and macrophages). In response to defense mechanism, the body will be expressed enzyme cyclooxygenase (COX) which functions convert arachidonic acid to prostaglandins.

Decreased secretion of hormones, especially estrogen, can trigger an increase in pro-inflammatory cytokines such as IL-1, IL-6 and TNF-α, which play a role in bone resorption and periodontal inflammatory reactions. One drug of choice for periodontitis is metronidazole. Systemic use of metronidazole can cause side effects, so an alternative material with a therapeutic anti-inflammatory effect is needed. One of the plants that have an anti-inflammatory effect is cassava leaves. The research objective was to analyse the potential of cassava leaf extract as an anti-inflammatory against the peripheral blood leukocyte profile in a mouse model of ovarian dysfunction and periodontitis. Methods: This was an experimental laboratory study with a post-test only control group design. The research sample consisted of 18 female rats divided into two large groups: the ovarian dysfunction group and the small periodontitis group. The making of mouse models of ovarian dysfunction and periodontitis rats was carried out for 28 days. After each group was divided into three groups treated with distilled water, metronidazole and cassava leaf extract for seven days. Blood was drawn from each mouse through the infraorbital plexus on day 1, day three, and 7. The blood that was taken was then performed to calculate the number of peripheral blood leukocytes using the counting room and the calculation of the type by visual means. Results: The results of the LSD test showed that there was a significant difference in the number of peripheral blood leukocytes between days in the group of rats with ovarian dysfunction (p≤0.05). Conclusion: Cassava leaf extract (Manihot esculenta Crantz) can reduce the profile of peripheral leukocytes in a mouse model of ovarian dysfunction and periodontitis.Keywords: Ovarian dysfunction, periodontitis, peripheral leukocytes profile, cassava leaf extract.
