Abstract

Breast cancer cases in Indonesia have risen in alarming rate. Herbal medicines have been developed to complement conventional cancer therapy and to lessen the negative effects of the therapies. Phycocyanin, blue-green photosynthetic pigment from Spirulina platensis, becomes a potential candidate of herbal medicine for cancer therapy due to its capability to eliminate various cancer cell line on in vitro level. This research aimed to analyse the effectivity of phycocyanin to induce cytotoxic and apoptotic activity of T47D cells (breast cancer cell line). MTT assay was perform to measure IC50 value. Double-staining assay and flow cytometry were applied to visualize the appearance of apoptotic cells and to measure the percentage of apoptotic and necrotic cells. Result showed that the IC50 value of phycocyanin towards T47D cells is 1650 ?g/mL. Phycocyanin was also proven to induce apoptosis at IC50 with the apoptosis percentage of 45.93%. This research presented different results from previous researches that used phycocyanin from saltwater Spirulina platensis. Based on the results of this study, phycocyanin has the potential to be developed as anticancer agent by inducing apoptosis.

Abstract

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.

Abstract

Latar belakang: Psoriasis pustulosa generalisata (PPG) merupakan salah satu jenis psoriasis yang jarang terjadi. Angka kejadian PPG 0,6-0,7 kasus per satu juta jiwa. Gejala khas PPG yaitu terdapat pus steril dengan ukuran 2-3 mm yang tersebar generalisata diatas kulit yang eritem. Terapi yang biasa digunakan diantaranya siklosporin, acitretin, atau metrotekstat. Tujuan: Tujuan dari kasus ini untuk membahas tentang faktor pencetus PPG, pilihan obat, komplikasi, dan efek samping dari terapi PPG jangka panjang.Kasus: Seorang wanita usia 37 tahun dengan riwayat psoriasis datang dengan keluhan terdapat pustula generalisata, makula eritem dan skuama. Faktor predisposisi dan pencetus pada pasien ini adalah obesitas dan stres emosional. Pasien pernah mendapatkan terapi siklosporin selama 3 tahun kemudian diganti asitretin satu tahun terakhir. Hasil histopatologi didapatkan gambaran abses munro dan parakeratosis sesuai dengan PPG. Didapatkan leukositosis dan kelainan tes fungsi hati pada pemeriksaan laboratorium, sehingga terapi kembali diganti dengan siklosporin dosis rendah selama 10 hari dan memberikan hasil yang memuaskan.Pembahasan: PPG merupakan penyakit autoimun. Stres emosional merupakan faktor yang paling berpengaruh; pada kasus ini pasien telah lama menderita PPG dan terapi sistemik jangka panjang, emosi pasien menjadi tidak terkontrol sehingga sering terjadi kekambuhan. Acitretin dapat menyebabkan kerusakan hepar; siklosporin dapat menjadi pilihan yang lebih baik. Simpulan: PPG masih menjadi masalah besar. Stres emosional merupakan faktor yang mempengaruhi kejadian PPG. Terapi jangka panjang dan efek samping menyebabkan ketidakpatuhan pasien untuk konsumsi obat. Penting bagi pasien untuk melanjutkan terapi obat sistemik dan mengontrol emosiKata kunci: Psoriasis pustulosa generalisata, Acitretin, Siklosporin, Kerusakan Hepar.Key Words: Psoriasis, Hypocalcemia, Hypoparathyroidism, Psoriasis of von ZumbuschPsoriasis is an autoimmune disease triggered by different conditions in genetically susceptible people. It is characterized by variable cutaneous manifestations including localized or disseminated pustules. Generalized pustular psoriasis (GPP) has two main clinical forms: von Zumbusch psoriasis, characterized by severe erythrodermia and scaling skin after the resolution of pustules, and the annular form. GPP may also present severe extracutaneous manifestations including pneumonitis, heart failure and hepatitis. Old reports showed a relationship between hypoparathyroidism and hypocalcemia as triggers for GPP highlighting the importance of adequate workup of the patient and possible therapeutic changes in acute situations. Here, we present a case of severe von Zumbusch psoriasis with life-threatening complications triggered by severe hypocalcemia secondary to hypoparathyroidism successfully treated with aggressive calcium reposition.Key Words: Psoriasis, Hypocalcemia, Hypoparathyroidism, Psoriasis of von Zumbusch

Abstract

Sea cucumber, Holothuria scabra, can be found abundantly in Indonesian seas, which is also known to possess several medicinal properties. Spirulina platensis is another marine resources that has recently been extensively researched for its medicinal ability, such as anti-inflammatory effect. This study aims to evaluate the efficacy of H. scabra extract combined with S. platensis extract in reducing inflammation. This study uses male Wistar rats as the study animal. Inflammation was induced by injecting carrageenan solution into the mice paw. Combination of H. scabra and S. platensis extract with various combination ratio (1:1; 1:2; and 2:1) was applied to the mice paw. Diclofenac sodium was used as the standard control therapy. Edema inhibition rate and anti-inflammatory efficacy were measured by analyzing the edema size and calculating the edema difference. Combination of H. scabra and S. platensis with 1:1 ratio has the largest edema inhibition volume compared to the other treatments. H. scabra and S. platensis combination outperforms the positive diclofenac sodium control group in terms of edema inhibition. The highest anti-inflammatory effect is obtained in the combination of H. scabra and S. platensis with 1:2 ratio, however, the anti-inflammatory efficacy is not as potent as the positive control. The effectivity of Holothuria scabra and Spirulina platensis extract in reducing the edema might be caused by their ability to reduce the levels of several inflammatory markers, including IL-6, NO, MMP9, and COX-2. This result suggests that H. scabra and S. platensis combination has anti-inflammatory effect shown in mice paw edema model.

Abstract

Background: One of the most common difficulties found in leprosy management is how to manage leprosy reaction, even though MDT has proven to be effective for the patients. Reversal reaction is associated with cell mediated immunity (CMI), consists of T-helper (Th) 1 and Th2 activities. Moreover, subset of CD4+ Th17 and CD25+ FOXP3 Treg were known to have an important role in leprosy’s natural history. Prior study showed a decreasing number of CD25+ FOXP3 Treg and increasing number of CD4+ Th17 in type II reversal reaction (ENL). However, the distribution of Th17 and Treg in type I reversal reaction (RR) has not yet been identified.Objective: To compare the distribution of CD4+ Th17 and CD25+ FOXP3 Treg between RR and ENL patient groups.Method: A total of 50 samples, consisted of 27 samples of reversal reaction (RR) and 23 samples of ENL, were collected. Observation of CD4+ RORg-T Th17 and CD25+ FOXP3 Treg were conducted with immunohistochemistry staining technique using anti FOX-P3 and anti RORg-T. Expression of CD4+ ROR-g Th17 and CD25+ FOXP3 Treg in percentage were analyzed using T-test.Result: There is a significant difference in mean CD4+ ROR-g Th17 and IL17 cell distribution for RR patient group (14.96% and 10.72%) compared with ENL (9.12% and 4.28%). No significant difference were found between mean CD25+ FOXP3 Treg and TGF-β cell distribution in RR patient group (6.12% and 5.44%) compared with ENL group (6.16% and 5.96%).Conclusion: There is a significant increment od CD+RORg-T Th17 and IL17 in RR patients group compared with ENL patients group. however, the distribution of CD25+ FOXP3+ Treg and TGF beta in RR has no significant difference campared with ENL.

Abstract

AbstractIntroduction: Wounds are a breakdown of tissue integrity / continuity that can lead to infection. Virgin Coconut Oil is a processed coconut product made by processing fresh coconut flesh at low temperature and has a high nutritional content. Ozone therapy is an alternative therapy that has disinfectant properties and can induce strong oxidative stress. Methods: This study was conducted on 50 Sprague-Dawley rats that had injuries. We performed full thickness wounds and administered ozonated doses of VCO to mice. We looked at shrinkage of wounds and TGF Beta levels in mice. Assessment was carried out on day 7 and day 14 to assess the wound and TGF-beta immunohistochemically. Results: There was a significant difference in the wound shrinkage variable between the negative control group and the group that received VCO offerings both on day 7 and day 14. We also found a significant difference in the TGF-beta variable between the negative control group and the group that received VCO offerings both on day 7 and day 14. Conclusion: The administration of ozonated virgin coconut oil was effective in increasing the expression of TGF-? in the full thickness defect of Sprague Dawley rats and was effective in increasing the reduction in wound size in the full thickness defect of Sprague Dawley rats.
