"Beberapa sistem pengaturan yang melibatkan jantung, pembuluh darah, ginjal mendukung patofisiologi hipertensi. Stres oksidatif merupakan faktor yang menghubungkan sistem-sistem tersebut. Stres oksidatif terjadi karena ketidakseimbangan antara antioksidan dan produksi spesies oksigen reaktif (ROS). Salah satu biota laut yang bisa digunakan dalam pengobatannya berasal dari kuda laut dengan kandungan senyawa yang dapat mencegah penyakit kardiovaskuler dan kaya akan kandungan antioksidan. Tujuan penelitian ini adalah untuk menganalisis pengaruh pemberian ekstrak kuda laut (Hippocampus comes L.) terhadap kadar SOD dan MDA darah dan ginjal pada mencit Ddy yang diinduksi Fenilefrin. Mencit dibagi menjadi 6 kelompok (n=4) secara acak yaitu kelompok normal, kontol negatif, kontrol positif (kandesartan sileksetil 2,1 mg/kgBB) dan kelompok uji ekstrak kuda laut (dosis 100, 200, 400 mg/kgBB) yang diberikan selama 14 hari. Seluruh hewan uji terlebih dahulu diinduksi fenilefrin (PE) selama 14 hari, lalu dilanjutkan diberikan perlakuan masing-masing selama 7 hari. Pengukuran kadar SOD dilakukan dengan Total Superoxide Dismutase (T-SOD) Activity Assay Kit (WST-1 Method), dan kadar malondialdehida (MDA) diukur menggunakan metode TBA. Penelitian ini menunjukkan bahwa pemberian ekstrak kuda laut (Hippocampus comes L.) pada variasi tiga dosis yang berbeda tidak memiliki perbedaan bermakna terhadap kadar SOD (nilai p = 0,0936) dan MDA (nilai p = 0,2393) darah, kadar SOD (nilai p = 0,3257) dan MDA (nilai p = 0,3685) ginjal dari mencit yang diinduksi fenilefrin dibandingkan dengan kelompok normal, negatif, dan positif. Dari hasil tersebut didapatkan bahwa ekstrak kuda laut (Hippocampus comes) tidak menyebabkan peningkatan kadar SOD dan tidak menurunkan kadar MDA pada darah dan ginjal mencit yang diinduksi fenilefrin.

Several regulatory systems involving the heart, blood vessels, kidneys, support the pathophysiology of hypertension. Oxidative stress is a factor that connects these systems with compounds that can prevent cardiovascular disease and is enriched by antioxidants. Blood pressure that exceeds normal limits can slow the development of kidney disease and prevent the heart from functioning properly. This research is conducted with the purpose to analyze the effect of administering seahorse (Hippocampus comes L.) extract towards the amount of SOD and MDA on blood and kidney of Phenylephrine-induced mice Ddy. The mice were divided into six groups (n=4) randomly: normal group (CMC Na 0.5%), negative control (CMC-Na 0.5%), positive control (candesartan cilexetil 2.1 mg/kgBW) and seahorse extract-tested group (dose 100, 200, 400 mg /kgBB) given for 14 days. All test animals were first induced by phenylephrine (PE) for 14 days, then continued with each treatment for 7 days. SOD levels were measured using the Total Superoxide Dismutase (T-SOD) Activity Assay Kit (WST-1 Method), while MDA levels were measured using TBA method. This research shows that administration of seahorse (Hippocampus comes L.) extract at three different dose did not cause significant differences in SOD (p value = 0.0936) and MDA (p value = 0.2393) levels from the blood, and SOD (p value = 0.3257) and MDA (p value = 0.3685) levels from the kidneys of mice induced with phenylephrine compared to the normal, negative, and positive groups. From these results it was found that seahorse extract (Hippocampus comes) did not cause an increase in SOD levels and did not reduce MDA levels in the blood and kidneys of mice induced with phenylephrine."

"Infertilitas adalah kelainan reproduksi yang ditandai dengan kegagalan kehamilan lebih dari satu tahun tanpa kontrasepsi meskipun berhubungan seksual secara rutin. Terapi hormonal yang mahal masih menjadi pilihan utama untuk mengatasi infertilitas akibat faktor biologis, sehingga diperlukan alternatif lain. Penelitian ini bertujuan untuk mengetahui apakah pemberian ekstrak kuda laut (Hippocampus comes L.) memengaruhi kadar albumin, globulin, dan total protein darah tikus Sprague-Dawley yang dikondisikan infertil dengan induksi DMPA. Ekstrak kuda laut diberikan kepada 30 tikus jantan yang dibagi menjadi 5 kelompok perlakuan, masing-masing dengan perlakuan berbeda. Hasil penelitian menunjukkan rerata terbesar dari total protein adalah kelompok DMPA ditambah ekstrak kuda laut 300 mg/kgBB (6,73 ± 0,35 g/dL). Rerata terbesar kadar albumin adalah kelompok DMPA ditambah 225 mg/kgBB (3,72 ± 0,10 g/dL). Rerata terbesar kadar globulin adalah kelompok kontrol (3,06 ± 0,18 g/dL). Berdasarkan uji ANOVA satu arah, tidak didapatkan signifikansi antarkelompok pada parameter total protein (p=0,837), albumin (p=0,812), maupun globulin (p=0,750). Hasil analisis ini menandakan pemberian ekstrak kuda laut tidak memengaruhi kadar protein darah tikus yang diinduksi DMPA.

Infertility is a reproductive disorder characterized by the failure to achieve pregnancy for over a year without contraception despite regular sexual intercourse. Expensive hormonal therapy remains the primary option to address infertility due to biological factors, hence the need for alternative treatments. This study aims to determine whether the administration of seahorse extract (Hippocampus comes L.) affects the levels of albumin, globulin, and total blood protein in Sprague-Dawley rats conditioned to be infertile with DMPA induction. The seahorse extract was administered to 30 male rats divided into 5 treatment groups, each receiving different treatments. The results showed that the highest average total protein was in the DMPA group with 300 mg/kgBW seahorse extract (6.73 ± 0.35 g/dL). The highest average albumin level was in the DMPA group with 225 mg/kgBW (3.72 ± 0.10 g/dL), and the highest average globulin level was in the control group (3.06 ± 0.18 g/dL). Based on one-way ANOVA, there was no significant difference between the groups for total protein (p=0.837), albumin (p=0.812), or globulin (p=0.750). This analysis indicates that the administration of seahorse extract does not affect the protein levels in the blood of DMPA-induced rats."

"Latar belakang: Infark Miokard (MI) merupakan salah satu penyebab utama morbiditas dan mortalitas di dunia. Salah satu mekanisme yang mendasari terjadinya MI ialah adanya produksi reactive oxygen species (ROS) berlebihan atau keadaan stres oksidatif. Berbagai tata laksana diupayakan untuk dapat mengatasi penyakit ini salah satunya adalah pengobatan herbal. Tanaman Centella asiatica telah dikenal memiliki berbagai efek farmakologikal yang bermanfaat, salah satunya adalah sebagai antioksidan. Penelitian ini bertujuan untuk mengetahui efek ekstrak air daun Centella asiatica terhadap parameter stres oksidatif, khususnya aktivitas SOD dan kadar MDA jaringan jantung tikus yang telah mengalami MI. Metode: Penelitian ini menggunakan sampel jaringan jantung tikus tersedia di laboratorium yang merupakan bagian dari penelitian besar berjudul “Efek Kardioproteksi Tanaman Herbal Indonesia (Moringa oleifera, Centella asiatica, Andrographis paniculata) melalui Aktivitas Antioksidan dan Antiinflamasi pada Model Infark Miokard Tikus yang diinduksi Isoproterenol.”. Pada penelitian ini digunakan tiga kelompok dari enam kelompok yang digunakan di penelitian besar tersebut. Kelompok pertama ialah normal tanpa perlakuan, kelompok kedua (Iso) diberi isoproterenol dengan dosis 85 mg/kgBB. Kelompok ketiga (Iso + ekstrak CA) diberi isoproterenol dosis 85 mg/kgBB dan ekstrak air daun Centella asiatica dosis 200 mg/kgBB. Kadar protein jaringan dihitung menggunakan uji Bradford. Aktivitas SOD jaringan diperiksa menggunakan EZSOD Assay Kit sementara kadar MDA diperiksa menggunakan metode TBARS. Hasil: Berdasarkan hasil penelitian ini, tidak ditemukan adanya perbedaan kadar MDA yang signifikan antar ketiga kelompok (p=0,105). Pada hasil pemeriksaan SOD, ditemukan penurunan yang tidak signifikan pada kelompok Iso (p=0,106) dibandingkan kelompok normal. Pada kelompok Iso + ekstrak CA ditemukan penurunan aktivitias SOD yang tidak signifikan (p=0,490) dibandingkan kelompok Iso. Kesimpulan: Pada penelitian ini, belum dapat dibuktikan bahwa ekstrak air daun Centella asiatica memiliki efek kardioprotektif terhadap aktivitas SOD dan kadar MDA jaringan jantung tikus.

Introduction: Myocardial infarction (MI) is one of the common causes of morbidity and mortality in the world. One of the underlying mechanisms of MI is due to excessive production of oxygen reactive species (ROS) in cells and tissues. This phenomenon is also known as oxidative stress condition. Many therapies are being developed to overcome MI such as medicinal herbs. Centella asiatica has been known for its useful therapeutic potential. For instance, it has some antioxidant compounds which can help reduce free radicals by scavenging them. Thus, this study aimed to analyze the effects of Centella asiatica water extract against SOD activity and MDA levels in isoproterenol-induced myocardial infarction in rats. Method: In this study, we used available rat heart tissues in the laboratory which were part of the previous study. Subjects were devided into three treatment groups as follows: normal, Iso, and Iso + extract CA. Isoproterenol were administered at 85 mg/kg BW and Centella asiatica water extract were administered in the third group at 200 mg/kg BW on the previous study. Bradford tests were performed to measure the concentration of total protein in samples. Activity of SOD were assessed by EZ-SOD Assay Kit. While levels of MDA were assessed by the TBARS assay method. Result: According to the findings of the study, there were non-significant differences in MDA levels among subjects in three groups (p=0,105). There was a non-significant decrease in activity of SOD (p=0,106) in the Iso group compared to the normal group. Also, there was a non-significant decrease in activity of SOD (p=0,490) in the Iso + extract CA group compared to the Iso group. These results are not in accordance with previous studies.Conclusion: In this study, it has not been proven that Centella asiatica water extract has cardioprotective effects against activitiy of SOD and MDA levels in isoproterenol-induced myocardial infarction in rats. This is probably due to some different treatments from previous studies. "

"Infertilitas pada pria dialami lebih kurang 30 juta orang serta berkontribusi terhadap 20-30% kasus infertilitas di seluruh dunia. Salah satu penyebab infertilitas pada pria adalah tingginya kadar reactive oxygen species. Kuda laut (Hippocampus comes L.) memiliki senyawa asam amino yang dapat berfungsi sebagai antioksidan sehingga berpotensi untuk meningkatkan motilitas dan viabilitas spermatozoa. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak kuda laut (Hippocampus comes L.) terhadap motilitas dan viabilitas spermatozoa manusia secara in vitro. Penelitian ini menggunakan spermatozoa manusia yang tidak diberi perlakuan sebagai kontrol dan perlakuan konsentrasi ekstrak 750, 1.000, 3.000, dan 5.000 ppm serta diinkubasi pada spermatozoa manusia selama 24 jam. Motilitas serta viabilitas spermatozoa diperiksa sebelum diberikan ekstrak dan pada jam ke-1, 3, dan 24 setelah pemberian ekstrak. Motilitas spermatozoa dianalisis dengan uji Kruskal-Wallis dan dilanjutkan dengan uji post-hoc Dunn. Viabilitas spermatozoa dianalisis dengan uji One-Way ANOVA dilanjutkan dengan uji post-hoc Dunnett. Hubungan antara konsentrasi ekstrak dan waktu inkubasi terhadap motilitas dan viabilitas spermatozoa dianalisis menggunakan uji Spearman-rho. Motilitas cenderung meningkat pada jam ke-1 setelah pemberian konsentrasi ekstrak 1.000 ppm (p=0,171;p>0,05) dan jam ke-24 setelah pemberian konsentrasi ekstrak 3.000 ppm (p=0,121;p>0,05). Viabilitas meningkat pada jam ke-24 setelah pemberian konsentrasi ekstrak 1.000 ppm (p=0,013;p<0,05) dan 3.000 ppm (p=0,016;p<0,05). Peningkatan konsentrasi ekstrak berkorelasi negatif dengan motilitas spermatozoa pada jam ke-3 (p=0,000;r=-0,818) dan berkorelasi positif viabilitas spermatozoa pada jam ke-24 (p=0,010;r=0,639). Peningkatan waktu inkubasi berkorelasi negatif terhadap motilitas spermatozoa (p=0,003;r=-0,783) dan viabilitas spermatozoa (p=0,010;r=-0,653). Pemberian ekstrak kuda laut (Hippocampus comes L.) dapat meningkatkan motilitas dan viabilitas spermatozoa manusia.

Male infertility is experienced by approximately 30 million people and contributes to 20-30% of infertility cases worldwide. One of the causes of male infertility is the high level of reactive oxygen species. The seahorse (Hippocampus comes L.) contains amino acid compounds that can function as antioxidants, potentially enhancing spermatozoa motility and viability. This study aims to investigate the effect of seahorse extract (Hippocampus comes L.) on the motility and viability of human spermatozoa in vitro. The study used untreated human spermatozoa as the control and treated them with different concentrations of seahorse extract (750, 1,000, 3,000, and 5,000 ppm), incubating them for 24 hours. Motility and viability of spermatozoa were examined before the extract was administered and at the 1st, 3rd, and 24th hour after the extract was given. Motility of spermatozoa was analyzed using the Kruskal-Wallis test and followed by the post-hoc Dunn test. Viability of spermatozoa was analyzed using One-Way ANOVA and followed by the post-hoc Dunnett test. Correlation between extract concentration and incubation time on motility and viability was analyzed using the Spearman-rho test. Motility tended to increase at the 1st hour after the administration of 1.000 ppm extract (p=0.171;p>0.05) and at the 24th hour after the administration of 3,000 ppm extract (p=0.121; p>0.05). Viability increased at the 24th hour after the administration of 1,000 ppm (p=0.013; p<0.05) and 3,000 ppm (p=0.016; p<0.05) extract. An increase in extract concentration was negatively correlated with spermatozoa motility at the 3rd hour (p=0.000;r=-0.818) and positively correlated with spermatozoa viability at the 24th hour (p=0.010;r=0.639) while incubation time both negatively correlated with spermatozoa motility (p=0.003; r=-0.783) and viability (p=0.010; r=-0.653). In conclusion, in vitro administration of seahorse extract (Hippocampus comes L.) can enhance the motility and viability of human spermatozoa."

"Latar belakang: Akumulasi volume latihan fisik yang berlebihan (overtraining/OT), dalam jangka panjang dapat menimbulkan penurunan performa yang disebut overtraining syndrome (OTS). Patofisiologi OTS banyak dihubungkan dengan stress oksidatif, kondisi ketidakseimbangan antara radikal bebas dan antioksidan endogen, yang dapat berujung pada gangguan kardiovaskular. Beberapa penelitan menunjukkan bahwa stres oksidatif dapat dihambat melalui suplementasi antioksidan. Hibiscus Sabdariffa Linn. (H. sabdariffa) adalah tanaman yang mengandung antioksidan tinggi.
Tujuan: Melihat efek OT terhadap tingkat stress oksidatif jantung tikus dan efek pemberian H. sabdariffa terhadap stress oksidatif jantung tikus OT.
Metode: Studi eksperimental menggunakan 25 tikus Wistar dewasa, 8-10 minggu, 300-350 gr, diacak menjadi lima kelompok: Kontrol (C), Kontrol+Hibiscus (C-Hib), Latihan Aerobik (A), Overtraining (OT) dan Overtraining+Hibiscus (OT-Hib). Dosis H. sabdariffa yang diberikan: 500 mg/kgBB/hari. Latihan fisik (A dan OT) dilakukan 5x/minggu selama 11 minggu. Dihitung kadar MDA, SOD dan GSH pada jantung tikus menggunakan spektrofotometri dan Nox2 pada jantung tikus menggunakan ELISA pada akhir Minggu 11.
Hasil: Pada kelompok OT-Hib kadar MDA secara bermakna mengalami penurunan, kadar GSH secara bermakna mengalami peningkatan, didukung dengan kadar SOD yang cenderung meningkat, namun tidak signifikan, dan Nox2 mengalami peningkatan yang tidak signifikan.
Kesimpulan: Overtraining menyebabkan kondisi stres oksidatif pada jaringan jantung tikus dan pemberian suplementasi H. sabdariffa memiliki potensi menangani stres oksidatif pada jantung tikus overtraining

Background: Accumulation of overtraining/OT volume, in the long run can lead to decreased performance called overtraining syndrome (OTS). Pathophysiology of OTS is associated with oxidative stress, a condition of imbalance between free radicals and endogenous antioxidants, which can lead to cardiovascular disorders. Some research shows that oxidative stress can be inhibited through antioxidant supplementation. Hibiscus Sabdariffa Linn. (H. sabdariffa) is a plant that contains high antioxidants.
Objective: This study was to look at the effect of OT on rat heart oxidative stress levels and the effect of giving H. sabdariffa to oxidative stress in OT rats.
Methods: The study was an experimental study using 25 adult Wistar rats, 8-10 weeks, 300-350 gr, randomized into five groups: Control (C), Control + Hibiscus (C-Hib), Aerobic Exercise (A), Overtraining (OT ) and Overtraining + Hibiscus (OT-Hib). Dosage of H. sabdariffa given: 500 mg/kg/day. Physical exercise (A and OT) is given 5x/week for 11 weeks. Calculated levels of MDA, SOD and GSH using spectrophotometry and Nox2 using ELISA at the end of Week 11.
Results: In the OT-Hib group, MDA levels significantly decreased, GSH levels significantly increased, supported by SOD levels which tended to increase, but were not significant, and Nox2 experienced an insignificant increase.
Conclusion: Overtraining can causes oxidative stress conditions in rat heart tissue, and supplementation of Hibiscus sabdariffa Linn. can handle oxidative stress in overtraining rat's heart.

"Gangguan keseimbangan hormonal dapat menyebabkan infertilitas pada pria, salah satunya adalah Hipogonadisme. Hipogonadisme ditandai dengan abnormalitas kadar hormon testosteron yang dapat mengganggu proses spermatogenesis. Kuda laut ( Hippocampus spp.) merupakan sumber daya kelautan yang digunakan sebagai pengobatan tradisional di wilayah asia untuk mengatasi infertilitas pada pria. Hippocampus comes merupakan salah satu spesies kuda laut yang memiliki habitat di perairan Indonesia, namun belum banyak penelitian yang meneliti pengaruh spesies kuda laut ini terhadap biomarker terkait infertilitas pria, terutama kadar Luteinizing Hormone sebagai hormon gonadotropin yang menstimulasi sekresi hormon testosteron, serta kajian histologi testikuler mengenai indeks meiosis dan indeks sel Sertoli. Induksi Depot Medroksiprogesteron asetat (DMPA) dapat mengganggu aksis hipotalamus-pituitari-gonad yang menyebabkan turunnya sekresi hormon gonadotropin serta hormon testosteron sehingga mempengaruhi proliferasi dan maturasi sel spermatogenik. Dua puluh delapan tikus jantan Sprague Dawley  diinduksikan DMPA 1,25 mg/kgBB pada minggu ke- 0 dan 12, kemudian dibagi menjadi empat kelompok, yaitu kontrol negatif (CMC Na 1%), dosis ekstrak 150 mg/kgBB, 225 mg/kgBB, dan 300 mg/kgBB. Parameter kadar LH tikus dianalisis menggunakan Enzyme-Linked Immunosorbent Assay (ELISA), sedangkan parameter indeks meiosis dan indeks sel Sertoli dianalisis melalui pemeriksaan histologi pewarnaan H&E. Hasil menunjukkan bahwa ketiga varian dosis tidak menghasilkan perbedaan yang bermakna antar kelompok pada ketiga parameter, namun cenderung mengalami peningkatan pada dosis 300 mg/kgBB setelah 18 minggu perlakuan.

Hormonal imbalances can lead to male infertility, one of which is hypogonadism. Hypogonadism is characterized by abnormal levels of testosterone hormone that can disrupt the process of spermatogenesis. Seahorses (Hippocampus spp.) are marine resources used in traditional medicine in Asia to address male infertility. Hippocampus comes is one of the seahorse species that inhabits the waters of Indonesia, but there have been few studies examining the effects of this seahorse species on biomarkers related to male infertility, especially the levels of Luteinizing Hormone as a gonadotropin hormone that stimulates testosterone secretion as well as histological studies of testicular meiotic index and Sertoli cell index. Induction of Depot Medroxyprogesterone Acetate (DMPA) can disrupt the hypothalamic-pituitary-gonadal axis, leading to a decrease in the secretion of gonadotropin hormones and testosterone, thus affecting the proliferation and maturation of spermatogenic cells. Twenty-eight male Sprague Dawley rats were induced with 1.25 mg/kg body weight of DMPA in weeks 0 and 12, then divided into four groups: negative control (CMC Na 1%), extract dose of 150 mg/kg BW, 225 mg/kg BW, and 300 mg/kg BW. The levels of LH in the rats were analyzed using Enzyme-Linked Immunosorbent Assay (ELISA), while the meiotic index and Sertoli cell index parameters were analyzed through histological examination using H&E staining. The results showed that the three dose variants did not produce significant differences between groups in all three parameters, but tended to increase at a dose of 300 mg/kg body weight after 18 weeks of treatment."

"[ABSTRAK
Latar Belakang: Endometriosis diperkirakan ditemukan pada 2-22% wanita usia reproduksi yang asimptomatik, sedangkan pada wanita yang mengalami dismenore, prevalensinya meningkat menjadi 40-60%. Terapi yang ada saat ini adalah terapi medikamentosa, terapi pembedahan, atau gabungan dari keduanya. Namun belum ada yang dapat berhasil menghilangkan penyakit ini. Hal ini dibuktikan dengan angka kekambuhan endometriosis yang cukup tinggi, yaitu 33,3-40,3%. Pada penderita endometriosis, terjadi proses inflamasi akibat adanya stress oksidatif yang berasal dari perdarahan siklik. Pada perdarahan siklik ini didapatkan heme dan besi yang merupakan suatu oksidan. Beratnya stress oksidatif yang terjadi dapat dilihat dari kadar malondialdehida dalam darah karena radikal bebas yang merupakan bagian dari ROS akan mengubah asam lemak jenuh menjadi aldehid dan malondialdehida (MDA). Telah diketahui bahwa kadar MDA pada jaringan endometriosis lebih tinggi secara bermakna dibandingkan dengan endometrium eutopik. Kurkumin diketahui mempunyai efek antiinflamasi, antioksidan, dan imunomodulator. Efek antioksidan dari kurkumin bekerja dengan cara mengurangi jumlah radikal bebas yang beredar.
Tujuan: Menilai pengaruh pemberian kurkumin terhadap stress oksidatif pada penderita endometriosis.
Metode: Penelitian ini merupakan suatu penelitian uji klinis acak tersamar ganda dengan kontrol pasien yang mendapat kapsul plasebo selama periode Desember 2014 ? Mei 2015. Pengambilan sampel dilakukan dengan consecutive sampling.
Hasil: Sejumlah 12 subjek dari kelompok kurkumin diberikan perlakuan dengan 1x100 mg kurkumin selama 2 bulan, sedangkan 12 subjek pada kelompok kontrol diberikan kapsul plasebo selama 2 bulan, setelah sebelumnya diambil MDA pre perlakuan. Satu pasien dari kelompok kurkumin dan 2 dari kelompok kontrol drop-out karena tidak kembali pada akhir bulan kedua untuk pengambilan MDA pasca perlakuan. Rerata awal kadar MDA subjek kelompok plasebo adalah 0,39 ± 0,39 nmol/ml dengan rerata kadar MDA di akhir intervensi 0,32 ± 0,14 nmol/ml. Penurunan tersebut tidak bermakna berdasarkan uji statistik dengan nilai p=0,80. Rerata awal (baseline) kadar MDA subjek dengan suplementasi kurkumin adalah 0,33 ± 0,21 nmol/ml dengan rerata kadar MDA pasca intervensi berkurang menjadi 0,31 ± 0,13 nmol/ml. Secara statistik penurunan kadar MDA pasca suplementasi kurkumin tidak bermakna (p=0,84). Tidak didapatkan perbedaan bermakna kadar MDA awal antar kedua kelompok (p=0,56). Demikian juga pada kadar MDA akhir intervensi dan perubahan (delta) kadar MDA antar kedua kelompok setelah intervensi, tidak dijumpai berbedaan bermakna secara statistik dengan p=0,85 dan p=0,81, berturut-turut
Kesimpulan: Tidak terdapat penurunan kadar MDA yang bermakna pada subjek dengan suplementasi kurkumin maupun plasebo.

ABSTRACT
Background: Endometriosis is estimated to be found in 2-22% asymptomatic reproductive women, while women with dysmenorrhea, the prevalence increased to 40-60%. Current management is medical therapy, surgical therapy, or a combination of both. But no one has been able to successfully eliminate this disease. This is proven by endometriosis recurrence rate is high enough, ranging from 33.3 to 40.3%. In endometriosis, inflammatory process occurs as a result of oxidative stress originating from cyclic bleeding. At this cyclic bleeding obtained heme and iron which is an oxidant. Free radicals that are part of the ROS (reactive oxygen species) will change the saturated fatty acids to aldehydes and malondialdehydes (MDA), so oxidative stress that occurs can be seen from plasma malondialdehyde levels. In recent study, MDA levels in endometriosis tissue was significantly higher than the eutopic endometrium. Curcumin is known to have anti-inflammatory, antioxidant and immunomodulatory effects. Antioxidant effects of curcumin works by reducing the amount of circulating free radicals.
Objective: Assess the effect of curcumin on oxidative stress in endometriosis patients
Methods: This study is a randomized double-blind clinical trial with control groups receiving placebo capsules for the period December 2014 - May 2015. Sampling was conducted by consecutive sampling.
Results: Twelve subjects of the treatment group was given curcumin 1x100 mg, while 12 subjects in the control group was given placebo capsules for 2 months. Peripheral blood was taken for MDA levels pre treatment. One patient from curcumin group and 2 from the control group dropped out because they do not come at the end of treatment for MDA measurement. The mean initial MDA level of placebo group was 0.39 ± 0.39 nmol / ml with a mean MDA levels at the end of the intervention 0.32 ± 0.14 nmol / ml. The decrease was not statistically significants with p = 0.80. The mean initial MDA levels of curcumin group was 0.33 ± 0.21 nmol / ml with a mean at the end of intervention was 0.31 ± 0.13 nmol / ml. The decrease was not statistically significants with p = 0.84. There were no significant differences between the initial MDA levels both groups (p = 0.56). Likewise, at MDA levels post intervention and delta between the MDA pre and post intervention on both groups, found no statistically significant with p = 0.85 and p = 0.81, respectively.
Conclusions: There was no significant decrease in MDA levels in subjects with curcumin supplementation or placebo., Background: Endometriosis is estimated to be found in 2-22% asymptomatic reproductive
women, while women with dysmenorrhea, the prevalence increased to 40-60%. Current
management is medical therapy, surgical therapy, or a combination of both. But no one has
been able to successfully eliminate this disease. This is proven by endometriosis recurrence

"Peningkatan stres oksidatif pada obesitas mempercepat onset proses senescence. Biji ketumbar (Coriandrum sativum L) mengandung antioksidan alami yang dapat menurunkan stress oksidatif. Penelitian ini bertujuan menilai efek pemberian ekstrak etanol biji ketumbar terhadap stres oksidatif dan cellular senescence pada hati tikus yang diinduksi obes. Induksi obesitas pada tikus Wistar menggunakan pakan tinggi lemak dilakukan selama 12 minggu. Ekstrak biji ketumbar 100mg/kgBB diberikan selama 12 minggu pasca induksi. Berat badan, Indeks Lee, IMT dan profil lipid plasma diukur pada minggu ke 12 dan 24. Setelah nekropsi pada minggu ke 24, diperiksakan MDA hati dan plasma, uji aktvitas spesifik katalase hati, aktivitas SA-β-Gal dan p16INK4A jaringan hati serta profil lipid plasma. Pemberian ekstrak biji ketumbar tidak menurunkan parameter obesitas yaitu berat badan (p=0,44), indeks Lee (p=0,35), IMT (p=0,97) dan kolesterol (p=0,09), namun menurunkan trigliserida (p=0,04) pada tikus obes. Terjadi penurunan MDA plasma (p=0,013) dan hati (p=0,008) disertai peningkatan aktivitas spesifik enzim katalase (p=0,01) pada tikus obes yang diberikan ekstrak biji ketumbar. Peran ekstrak biji ketumbar terhadap perbaikan status stres oksidatif dapat menghambat senescence yang tampak menyebabkan penurunan p16INK4A (p=0,006) namun tidak menurunkan aktivitas SA-β-Gal (p=0,277) pada hati tikus yang diinduksi obesitas

Increased oxidative stress in obesity accelerates the onset of the senescence. Coriander seed (Coriandrum sativum L) contains natural antioxidants that can reduce oxidative stress. This study aimed to assess the effect of coriander seed ethanolic extract on oxidative stress and cellular senescence in the liver of obese rats. Obesity induction in Wistar rats using high-fat diet was carried out for 12 weeks. Coriander seed extract 100mg/kg BW was administered 12 weeks post-induction. BW, Index Lee, BMI, and plasma lipid were measured at 12nd and 24th weeks. After necropsy at 24th week MDA, catalase-specific activity test, SA-β-Gal activity and p16INK4A of liver tissue, also plasma profile lipids and MDA were examined. Coriander seed extract did not reduce BW (p=0.44), Lee's index (p=0.35), BMI (p=0.97) and cholesterol (p=0.09), but decreased triglycerides (p=0.04) in obese rats. Plasma and liver MDA was decreased (p=0,013 and p=0.008) accompanied by an increase in specific activity of the catalase enzyme (p=0.01) in obese rats given coriander seed extract. The role of coriander seed extract in improving oxidative stress status inhibits senescence which appeared to cause a decrease in p16INK4A (p=0.006) but did not decrease SA-β-Gal activity (p=0.277) in the liver of obese induced rats."
