Sappan wood (Caesalpinia sappan L.) is a plant used by the community to mix drinking. The antioxidant index of Sappan wood extract has a higher value than commercial antioxidants to counteract oxidative free radicals and improve the body's defense system. The use of Sappan wood drinking in society is often used in daily so it is necessary to do a chronic toxicity test to observe the response to prolonged use of the system in the body. Kupffer cells are an important part of the innate immune system, acting as “scavengers” and phagocytes. A study that aims to see the chronic toxicity studies of the ethanolic extract of Sappan wood on the number of Kuffer cells in the liver has been carried out on 60 Wistar rats divided into 12 groups. The group was the negative control group, doses 100 mg/kgBW, 200 mg/kgBW, 300 mg/kgBW, 400 mg/kgBW and 500 mg/kgBW of extract Sappan wood which were divided into male and female groups. Each group was given ethanol extract of Sappan wood for one year orally. The results showed a significant increase in Kupffer cells in the female group at a dose of 100 mg/kgBW and the male group at 200 mg/kgBW with significant values, respectively, p<0.001 p = 0.004.
Fungi are eukaryotic and opportunistic organisms that can cause damage and disease. Fungi can be identified by direct staining. The composition of the dyes used in fungi staining are toxic, mutagenic and harmful to laboratory personnel and the environment. Consequently, it is necessary to consider use fungi dye continuously, so its need alternative safety dyes to identify fungi in the laboratory. This research aims to determine the potential of iodine lactoglycerol with different concentrations (1.25%, 2.5%, and 5%) as an alternative dye for fungi in the laboratory. The research method used experimental design. The samples originate from moldy bread and made 27 of microscopic slides. The microscopic slides were observed with objective 40x magnification. The parameters assessed in this study were the structure and morphology of fungi including hyphae, conidiophores, vesicles, sterigmata and conidiospores and color intensity using the image analysis of ImageJ. The results showed that various concentrations of iodine lactoglycerol can staining the structure and morphology of the fungi properly and clearly. The value of color intensity of each concentration measured has a different average. The highest average value of color intensity concentration was 5% and the lowest was 1.25%. However, the result of ANOVA test showed a significance of 0.380 (P> 0.05), which means that is no difference significantly from three of various concentrations. The result showed that the difference concentration of iodine lactoglycerol does not affect the color intensity. The conclusion of this study was iodine lactoglycerol solution can be used as an alternative dye or Lactophenol-cotton Blue (LPCB) substitute for fungi identification. It is recommendation for further research be carried out regarding the decrease in the concentration of alternative color solutions below 1.25%, the incubation time for the preparation of the preparations, and the color stability of the prepared mushroom preparations.
Coffee processing into fast food ingredients that must be done in order to get maximum results. Behind the processing there are various problems that arise, one of them are the presence of solid waste in the form of pulp coffee. Based on several studies, coffee pulp turned out to have high antioxidants.This research was conducted an acute oral toxicity test of the maximum dose (2000 mg/kg BW) of ethanol extract of coffee pulp was tested on mice for 24 hours. Acute oral toxicity studies of coffee pulp based on guidelines for National Drug and Food Control in female mice. The study was conducted in 2 groups of test animals consisting of a negative control group and an acute oral treatment group. Each group of 5 mice were treated for 24 hours. After treatment, the object was analyzed by histological observations descriptively. Descriptive histological analysis (qualitative analysis) of the liver of female mice showed no difference between the study groups. The treatment group that was given ethanol extract of coffee pulp showed a normal nucleus which was shown by the appearance of scattered chromatin beads. This is in line with the description of the normal cytoplasm like a group of normal mice. The maximum dose of 2,000 mg / kg for acute oral testing for 24 hours does not show microscopic changes in female mice.Recommendation for further research is to conduct oral subchronic and chronic toxicity testing in the normal group and in groups given free radical-producing compounds with various examinations of other organs. Keywords: health drinks, antioxidant, acute toxicity, maximum dose.
Histomorphological assessment of the placenta and fetus was more effective in assessing fetal development on a research scale for determined an active substance during the gestation period in experimental animals. The placenta and fetus connect in the development process. This study aimed to analyze the effect of giving ethanol extract of sappanwood on white rats’ placenta and fetal organs, which were examined histologically at 20 days pregnant rats. The pregnant rats were divided into six groups: The negative group was given aquadest, and treatment groups were given an ethanolic Sappan wood extract 100;200;300;400;500 mg/kg BW. Euthanized with CO2 and cesarian section was performed on pregnant rats on the 20th gestational day. Observation to record fetal body weight, body length, mean placental weight, and the histology of the placental area. Histomorphometry was used to measure the area of the fetal placental region. The group with sappan wood extract had no statistically significant difference in fetal body weight, fetal body length, fetal tail length, the weight placenta, and histomorphometry of the placenta compared to the control group (p > 0.05); this showed that the ethanolic extract of sappan wood does not have a toxic effect on the development of the placenta, which can interfere with fetal development during pregnancy. Sappan wood extract had a nontoxic effect on the placenta and fetal rat development on histological examination, even at the highest dose of 500 mg.kg-1 bw.
METHODS: The research method used in this research was experimental laboratory with pre-and posttest only control group design. RESULTS: The result shows that the extradiol level which has range of 26.30–31.03 from 28 experimental animals measured, this showed more measurement diameter which has not had measurement addition compare with the wide percentage of measurement. The result shows strong correlation between digitalized measured wide follicles to the changing of estradiol level with value of 0.453. The result of comparation between estradiol level and measured diameter shows weak correlation. This shows that manual measurement of follicle diameter still weak to the changing of estradiol level. CONCLUSION: There is strong correlation between measured wide area follicle used ImageJ applications to the changing of estradiol level compare to the measurement of follicle diameter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
