Body lotion is a skincare cosmetics products that usually contain preservatives as inhibitors of bacteria and fungi growth. According to the Food and Drug Supervisory Agency of Indonesian Republic, 2011: HK.03.1.23.08.11.07517, in which the preservative levels of nipagin (methyl paraben) in a body lotion must be 0.4%, Preservative level over 0.4% may result in skin irritation and allergic reactions. The purpose of this study was to determine the nipagin’s essence and levels in body lotions sold in Gorontalo City. Nipagin’s identification was carried out with a qualitative analysis using Thin Layer Chromatography and color change using 2% of deniges reactor and sodium nitrite, while the quantitative analysis was carried out with spectrophotometry UV-Vis at 258 nm wavelength that was previously extracted with 96% of ethanol solvent. The results of the qualitative study show that four (A, D, E, and F) out of six samples of body lotions: A, B, C, D, E, and F contained preservatives. Quantitatively, the levels of nipagin) on the four samples are sequentially shown as follows: by A:0.38%, D:0.04%, E:0.14%, F:0.14%. All in all, the samples are entirely eligible according to the Regulotions of the National Agency of Drug and Food of Indonesian Republic 2011: HK.03.1.23.08.11.07517.

Bromelain is a proteolytic enzyme or natural protease found in tissues, including the stem, fruit, and leaves of pineapple (Ananas comosus var. comosus) and other plant species of the Bromeliaceae family. Bromelain is known as an efficient debdriding agent because it is beneficial in  burn healing and tissue regeneration. This research aims to determine the effectiveness of bromelain enzyme for burns wounds in rabbits (Oryctolagus cuniculus). This research began with the optimization of carbopol 940 base preparations with variations in concentration, namely Formula 1 (F1) for 0,5%, Formula 2 (F2) for 1%, and Formula 3 (F3) for 1,5%. The evaluation of the gel formulation includes an organoleptic test, homogeneity test, pH test, viscosity test, adhesive force test, and spreadability test. The evaluation result indicates the base concentration in Formula 1 (F1) at 0,5% has met the requirements for a gel preparation. Formula 1 (F1) for 0,5, then combined with varying concentration of bromelain, namely Formula 1A (0,1%), Formula 1B (0,5%), and Formula 1C (1%). The gel formulation wa re-evaluated, including an organoleptic test, homogeneity test, pH test, viscosity test, adhesion test, spreadability test, irritation test, and in vivo test. In vivo effectiveness testing and irritation testing were conducted on five treatment groups, namely a positive control group (Bioplacenton®), Formula 1A (0,1%), Formula 1B (0,5%), Formula 1C (1%), and a group without treatment, then observed for 15 days. The observation data were processed using the One Way ANOVA test. Based on the results of the irritation test, Formula 1A (0,1%). Formula 1B (0,5%) and Formula 1C (1%) did not cause skin irritation. In the in vivo test, Formula 1C (1%) indicated the fastest recovery compared to other treatment groups, as evidenced by the decrease in wound diameter and visual observation, where the wound had started to close completely on day 15 of observation.
菠萝蛋白酶是一种蛋白水解酶或天然蛋白酶,存在于菠萝(Ananas comosus var. comosus)和其他菠萝科植物的茎、果实和叶子等组织中。菠萝蛋白酶是一种有效的去骨刺剂,因为它有利于烧伤愈合和组织再生。本研究旨在确定菠萝蛋白酶对兔子(Oryctolagus cuniculus)烧伤伤口的疗效。研究首先优化了浓度不同的 carbopol 940 基础制剂,即浓度为 0.5%的配方 1(F1)、浓度为 1%的配方 2(F2)和浓度为 1.5%的配方 3(F3)。对凝胶配方的评估包括感官测试、均匀性测试、pH 值测试、粘度测试、粘合力测试和涂抹性测试。评估结果表明,配方 1(F1)中 0.5%的碱浓度符合凝胶制剂的要求。配方 1(F1)为 0.5%,然后与不同浓度的菠萝蛋白酶结合,即配方 1A(0.1%)、配方 1B(0.5%)和配方 1C(1%)。对凝胶配方进行了重新评估,包括感官测试、均匀性测试、pH 值测试、粘度测试、粘附性测试、铺展性测试、刺激性测试和体内测试。对五个处理组进行了体内有效性测试和刺激性测试,即阳性对照组(Bioplacenton®)、配方 1A(0.1%)、配方 1B(0.5%)、配方 1C(1%)和未处理组,然后观察 15 天。观察数据采用单向方差分析进行处理。根据刺激性试验的结果,配方 1A (0.1%)配方 1B(0.5%)和配方 1C(1%)不会对皮肤造成刺激。在体内试验中,配方 1C(1%)与其他治疗组相比恢复最快,这体现在伤口直径的缩小和肉眼观察上,在观察的第 15 天,伤口已开始完全闭合。

Hypertension is a condition that can affect pregnancy. High blood pressure during pregnancy can hinder fetal and uterine growth, lead to fetal death in the womb, and result in premature birth. These complications can be minimized with appropriate antihypertensive therapy. The objective of this study is to determine the incidence rate, management, and accuracy of antihypertensive treatment according to the reference standards of the 2016 Preeclampsia National Medical Service Guidelines (PNPK). This research was an observational descriptive study where the data obtained were secondary data collected retrospectively from medical records at Regional Public Hospital of Toto Kabila from September 2022 to May 2023. The sample was taken using a saturated sampling technique, so the sample in this study included all pregnant women diagnosed with preeclampsia. The results of the study obtained 65 patients, consisting of 36 severe preeclampsia patients and 29 mild preeclampsia patients. The study showed that hypertension in pregnant women was often found in the age group of 26-35 years, with 25 patients (39%), and in the third trimester of pregnancy, with 23 cases, while 2 experienced hypertension in the first trimester. 12 patients were diagnosed with severe preeclampsia and 13 patients with mild preeclampsia. The treatment of hypertension in pregnant women for mild preeclampsia included methyldopa (34%) and nifedipine (7%). For severe preeclampsia, single therapy included methyldopa (39%), amlodipine (8%), and combination therapy such as nifedipine + methyldopa (36%) and methyldopa + amlodipine (17%). The accuracy of antihypertensive drug use in pregnant women based on the 2016 Preeclampsia PNPK was 86%, including appropriate indications, correct drugs and correct doses.

Diabetes mellitus is a disorder of blood sugar metabolism chronically characterized by high blood sugar levels resulting from impaired insulin secretion, insulin resistance, or both. Treatment of diabetes mellitus consists of four pillars: education, medical nutrition therapy (MNT), and physical and pharmacological therapies. One of the plants that can be used as a medicinal ingredient is guava leaves. Guava (Psidium guajava L.) leaves are a group of herbal plants with a chemical content that is good for health. Therefore, guava (Psidium guajava L.) leaves are plants that are efficacious as medicine. This plant contains secondary metabolites that act as antidiabetics. Thus, the research aimed to determine the effectiveness of ethanol extract of guava (Psidium guajava L.) leaves on the decrease in blood sugar levels in male mice. The research method employed was maceration, phytochemical screening, and antidiabetic testing with the pre-test and post-test control group design methods to determine if there was a decrease after administration of the extract. The findings indicated that the phytochemical screening test found that guava (Psidium guajava L.) contained secondary metabolites, including alkaloids, flavonoids, and tannins. In contrast, the antidiabetic test revealed that three extracts with concentrations of 50 mg, 100 mg. and 200 mg could decrease blood sugar levels by 15%, 21%, and 47%, respectively. From these findings, it can be concluded that antidiabetic compounds which play a role in the ellanol extrict of guava (Psidium guajava L.) leaves are alkaloids, flavonoids, and tannins.
糖尿病是一种血糖代谢紊乱的慢性疾病,其特点是由于胰岛素分泌受损、胰岛素抵抗或两者兼而有之而导致高血糖。糖尿病的治疗包括四大支柱:教育、医学营养疗法(MNT)、物理疗法和药物疗法。番石榴叶是可用作药用成分的植物之一。番石榴(Psidium guajava L.)叶是一类草本植物,其化学成分对健康有益。因此,番石榴叶是具有药效的植物。这种植物含有可作为抗糖尿病药物的次级代谢物。因此,本研究旨在确定番石榴叶乙醇提取物对降低雄性小鼠血糖水平的效果。采用的研究方法是浸渍、植物化学筛选和抗糖尿病测试,并通过前测和后测对照组设计方法来确定服用提取物后血糖是否下降。研究结果表明,植物化学筛选试验发现番石榴(Psidium guajava L.)含有次生代谢物,包括生物碱、黄酮类化合物和单宁酸。而抗糖尿病试验则表明,浓度分别为 50 毫克、100 毫克和 200 毫克的三种提取物可使血糖水平分别降低 15%、21% 和 47%。从这些发现中可以得出结论,在番石榴叶鞣醇提取物中起抗糖尿病作用的化合物是生物碱、黄酮类和单宁酸。

Dysregulation of the oncoprotein c-Myc (Myc) is involved in many types of cancer. Myc is a sequence-specific transcription factor that regulates the transcription of genes involved in the control of cell proliferation and apoptosis through mechanisms that are not well understood. The method of this research is experimental. The experiment result will be described.  Some processes will be done by polymerase chain reaction (PCR) to amplify the gene and then it will be extracted to pure the targeted gene. This research has been succesful to purify 3×Myc PKG-Puro-Poly A gene. c-MYC (hereinafter MYC) is an oncoprotein consisting of 439 amino acids contains a well-characterized C-terminal DNA compound and an N-terminal transactivation domain (TAD). The C-terminal region »100 residues comprises a basic leucine zipper-helix-loop-helix (bHLH-LZ) segment that regulates heterodimerization between MYC and its partner bHLH-LZ MAX mediate in their binding to gene promoters.

Purple eggplant skin (Solanum melongena L.) is one of the herbal plants that contain compounds such as flavonoids, alkaloids, saponnins, tannins, and terpenoids that are beneficial for health. This research is a laboratory experimental study that aims to determine the level of acute toxicity (LC50) of the ethanol extract of purple eggplant skin (Solanum melongena L.) using the Brine Shrimp Lethality Test (BSLT) method. Purple eggplant peel extraction was carried out using 70% ethanol as solvent. This test was conducted using 10 Artemia salina Leach larvae with 3 replications at 6 concentration variants, which are 500 ppm, 250 ppm, 125 ppm, 50 ppm, 25 ppm, and 12.5 ppm, along with negative controls. The larval mortality rate was observed after 24 hours of adding extract. The result of probit analysis showed that the LC50 value of the ethanol extract of purple eggplant skin (Solanum melongena L.) was 100.8 ppm. Moreover, the results of LC50 1000 ppm indicated that the ethanol extract of purple eggplant skin (Solanum melongena L.) was considered toxic and potential to be an anticancer agent.
