Abstract

Herbal yang berperan sebagai antioksidan dan antikanker diantaranya temulawak. Penelitian pengaruh ekstrak temulawak terhadap hematologi tikus pada pengujian keamanan subkronis dilakukan pada penelitian ini.  Parameter hematologi yang ditentukan adalah nilai hemoglobin, hematokrit, dan jumlah leukosit. Hewan coba yang digunakan adalah tikus jantan dan betina dari galur Sprague Dawley. Herbal yang diberikan sebagai pengobatan adalah ekstrak etanol 70% temulawak yang diberikan sebanyak 5 hari dalam seminggu selama 28 hari dengan dosis bertingkat mulai dari 45 mg/Kg BB hingga 5.625 mg/kg BB. Hasil yang diperoleh adalah perlakuan terakhir tidak ada tikus yang mati. Berdasarkan pengukuran diperoleh nilai hemoglobin antara 12,57-17,97 g/dL, nilai hematokrit antara 31,77-51,57%, dan jumlah leukosit antara 5,01-23.22x103 sel/μL (normal). Kesimpulan dari penelitian ini adalah bahwa dosis lebih besar dari 5625 mg/kg BB merupakan nilai LD50 untuk ekstrak etanol 70% temulawak. Pemberian ekstrak etanol 70% temulawak hingga dosis 5.625 mg/kg BB selama 28 hari pada tikus jantan dan betina memberikan efek penurunan terhadap nilai hemoglobin, hematokrit, dan leukosit, namun nilainya masih dalam batas normal. Tidak ada perbedaan nyata antara tikus jantan dan betina pada hasil pengukuran nilai hemoglobin, hematokrit, dan leukosit. Kata Kunci: Dosis, Hematologi, Subkronis, Temulawak, Tikus  Herbs that act as antioxidants and anticancer include temulawak. Research on the effect of temulawak extract on rat hematology in subchronic safety testing was carried out in this study. The determined hematological parameters were the value of hemoglobin, hematocrit and the number of leukocytes. The experimental animals used were male and female rats from the Sprague Dawley strain. The herbs given as treatment were an ethanolic extract of 70% temulawak which was given 5 days a week for 28 days with a graduated dose ranging from 45 mg/Kg BW to 5625 mg/kg BW. The results obtained are the last treatment no rat died. Based on the measurement of hemoglobin values obtained between 12.57 to 17.97 g/dL, hematocrit values obtained between 31.77 to 51.57% and leukocyte counts obtained between 5.01 to 23.22x103 cells/μL were still in the normal range. The conclusion of this study is that a dose greater than 5,625 mg/kg BW is the LD50 value for the ethanol extract of 70% temulawak. Giving 70% ethanol extract of temulawak until a dose of 5,625 mg/kg BW for 28 days to male and female rats had a decreasing effect on hemoglobin, hematocrit, and leukocyte values, but the values were still within normal limits. There is no significant difference between male and female rats in the measurement results of hemoglobin, hematocrit, and leukocyte values.

Abstract

Stress conditions will trigger the histone hyperacetylation process due to histone acetyltransferase p300/CBP (HAT PCAF) constantly transfers acetyl groups from acetyl-CoA to conserved lysine residues on histone proteins to form ε-N-acetyllysine. This can be a cause of cancer. The purpose of this study was to investigate the potential mechanisms and inhibition of PCAF HAT by chemical components of C. xanthorrhiza namely, curcumin, demethoxycurcumin, bisdemethoxycurcumin, and xanthorrizhol using in silico, the molecular docking method.  Results showed that the components of C. xanthorrhiza as ligands have the capability to inhibit the binding of acetyl-CoA to histone. These results can be used to predict the inhibitory mechanisms exhibited by C. xanthorrhiza components, as competitive and noncompetitive substances. We hypothesize that C. xanthorrhiza components resemble a substrate, leading to prevention of the natural substrate (histone) to bind to the enzyme, and hence block the product formation. The smallest free Gibs energy was exhibited by curcumin on chain B and by bismethoxycurcumin on chain A, with values of -8.8 and -8.4 Kcal/mol, respectively.

Abstract

Sheep breeders generally raise their sheep by releasing and allowing their livestock to graze wildly. This causes the sheep to receive feed intake with unbalanced nutrition. One of the student programs in the KKN-T IPB University in Pantai Mekar Village, Muara Gembong District, Bekasi Regency, were checking physical conditions, socializing management of sheep maintenance and distribution of vitamin B complex which to improve the health of the sheep. It was reported that four sheep were found dead after B complex vitamin administration to in four days. The sheep cadavers were brought to the School of Veterinary and Biomedical Sciences, IPB to undergo carcass surgery or necropsy to reveal the cause of death. The results of necropsy found Haemonchus contortus worm infestation in the abomasum of sheep, accompanied by accumulation of fluid under the skin, chest cavity, stomach, and lungs. The cause of death of the four sheep based on necropsy was caused by severe infestation of the Haemonchus contortus type of worm and malnutrition, which lead to hypoalbuminemia and progressed to edema in the lungs, which resulted in shortness of breath (dyspnea). In this case the necropsy results showed that the administration of vitamin B complex was not the cause of the death of the sheep.

Abstract

Honey is rich in phenolic and flavonoid compounds that have the potential as antioxidants. The heating treatment of honey is also known to affect the honey compound. This study aimed to determine the best Indonesian A. dorsata honey from various locations based on the level of total phenolics compounds, flavonoids, and antioxidant capacity due to variations in heating temperature. The procedures carried out in this study included: heating the sample with variations (room temperature, 65 oC, and 121 oC), measuring total phenolic content using the Folin-Ciocalteau method, measuring total flavonoid content using the AlCl3 colorimetric method, and testing antioxidant activity using the DPPH method. Each honey's total phenolic, flavonoid, and antioxidant activity are affected by its origin. The impact of heating at 65 oC and 121 oC resulted in various changes between honey samples (p<0.05). The best A. dorsata honey overall was found in Flores honey after heating at 121 oC heating treatment with total phenolic content of 4.96 mgGAE/mL, total flavonoids of 1.173 mg QE/mL, and IC50 5.76 g/L.

Abstract

Actinomycetes are known to be a source of natural products and drugs. Gordonia terrae, an actinomycete pigment producer, shows potential in producing pigment with antimicrobial activity. This study aims to determine the antimicrobial activity of the active pigment fraction produced by the actinomycete G. terrae, assess the effects of the active pigment fraction on microbial cells, and identify the types of compounds present in the fraction. The pigment extract exhibited antimicrobial activity against Gram-positive bacteria and fungi. Specifically, it showed activity against Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25293, and Candida albicans ATCC 10231. Furthermore, the study evaluated the antimicrobial activities of the active fractions, revealed the active fraction had better antimicrobial activity than the crude extract. Scanning electron microscopy (SEM) confirmed that the active fraction of the pigment causes damage to B. subtilis ATCC 6633 cells, inhibits the formation of filaments in C. albicans ATCC 10231, and alters the normal shape of the cells. LC-MS/MS results showed that the active fraction contained several compounds known for their antimicrobial activity. Among the dominant compounds identified were cholestyramine, aminopregnane, and sphinganine. Thus, this study demonstrated that the orange pigment extract derived from G. terrae JSN1.9 exhibits promising antimicrobial activity.
