Introduction: Drug Induced Liver Injury (DILI) is a liver injury caused by drug toxicity. About 41 out of 100.000 people suffer liver damage due to DILI. Most of this injury caused by excessive use of paracetamol. Meniran (Phyllanthus niruri Linn.) contains antioxidants that can protect liver from damage. The aim of this research was to investigate the hepatoprotective effect of meniran extract on histological damage in liver cells induced by paracetamol. Methods: This was laboratory experimental research with post test only controlled group design. This research was conducted in Histology Laboratory FK UNS. Samples were 30 mice obtained by purposive sampling which characteristics were Swiss webster type, male, 2-3 months old, 20 gr of each weight. Samples divided randomly into 5 groups, each group has six mice. The normal group (KN) was given distilled water only. The negative control group (KK (-)) was given paracetamol toxic dose only. The positive control group (KK (+)) was given Curcuma and paracetamol toxic dose. A gradual dose (2.8 mg and 5.6 mg) of meniran extract was given daily to the first treatment group (KP 1) and second treatment group (KP 2) for 14 days respectively and added with paracetamol toxic dose (5 mg) on day 8th to 14th orally. On day 15th, mice were sacrificed and liver were taken for preparation with HE staining. Liver cells damage was identified by counting nucleus with pyknosis, karryorhexis, and karyolysis from 100 liver cells. Data was analyzed using One-Way ANOVA and Post Hoc Multiple Comparisons-LSD (? = 0.05). Results: One-Way ANOVA showed that there was a significant difference between 5 groups (p < 0.05). Post Hoc Multiple Comparisons-LSD showed that there were significant differences (p < 0.05) between KN-KK (-), KN-KK (+), KN-KP 1, KN-KP 2, KK (-)-KK (+). KK (-)-KP 1, KK (-)-KP 2, KK (+)-KP 1, KP 1-KP 2, but there was not significant difference between KK (+)-KP 2 (p > 0.05). Conclusions: Meniran extract has hepatoprotective effect on histological structure damage of mices liver cells induced by paracetamol in a dose dependent manner.

Introduction: Dengue virus is a type of virus that causes various reactions, from asymptomatic infection to harmful manifestations, such as dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). Currently, the treatments of DHF cases have been limited to symptomatic and supportive therapies only. Therefore, it is necessary to develop new strategies in facing these cases. One of them is by using natural ingredients with antiviral potential. The aim of this study is to understand the antiviral effects of the ethanol extract of red ginger rhizome (Zingiber officinale Linn var. rubrum) against dengue virus in vitro. Methods : The subject of this research was Dengue virus serotype 2 strain New guinea C (DENV-2 NGC) which was infected into Huh-7 cell line. The research was divided into 2 parts. The first was inhibition test of the extract against DENV-2 which was assessed by average of infectivity percentage with Focus Forming Unit assay method. The second was toxicity test of the extract in Huh 7 cells which was assessed by average of viability percentage by MTT assay method. The herb extract effective as a Dengue antivirus was defined by average infectivity percentage of ? 20% and average viability percentage of > 50%. Results: Ethanolic extract of Red Ginger rhizome (Zingiber officinale Linn var.

Introduction: Measurement of hemoglobin concentration can be done by hematology analyzer (HA) cyanmethemoglobin method (gold standard) and point-of-care testing (POCT) electrode-based biosensor method. POCT electrode-based biosensor method is one of the hemoglobin POCT and has not been studied before in Indonesia. This study examined the difference and correlation hemoglobin concentration by HA cyanmethemoglobin method and POCT electrode-based biosensor method. Methods: This was a cross sectional study in 4 senior high schools of Sukoharjo in Indonesia on Desember, 2016. Senior high schools were selected using a simple random sampling and senior high schools grade selected using a stratified random sampling. Among 173 grade 10 and 11 senior high school girls in this study the capillary and venous blood samples were collected. Capillary blood sample collected was immediately processed to measure the hemoglobin concentration using POCT electrode-based biosensor method and venous blood sample was collected to measure the hemoglobin concentration using HA cyanmethemoglobin method. Statistical analyses used were Mann-Whitney and Spearmans correlation coefficient (?=0.05). Results: Hemoglobin concentration determined by the POCT electrode-based biosensor method compared to HA cyanmethemoglobin method was significantly different (p=0.000 ) and there was positive moderate correlation (r=0.438; p=0.000). Conclusions: Hemoglobin concentration assessment by POCT electrode-based biosensor method has shown significantly different and positive correlation with HA cyanmethemoglobin method.

Pendahuluan: Asma merupakan suatu penyakit saluran pernapasan yang disebabkan karena adanya proses inflamasi kronik. Asma menyebabkan terjadinya gejala pernapasan seperti wheezing (mengi), sesak napas, dada sesak dan batuk yang terjadi terutama pada malam hari atau menjelang pagi hari. Jumlah kasus asma di Jawa Tengah pada tahun 2013 sebesar 113.028 kasus dan kasus paling banyak terdapat di Kota Surakarta yaitu 10.393 kasus. Gejala asma lebih sering muncul pada malam hari atau menjelang pagi hari. Gangguan pernapasan yang muncul dapat mengganggu aktivitas tidur sehingga menyebabkan menurunnya kualitas tidur seseorang. Selain itu, gangguan pernapasan saat tidur akan semakin berat apabila seorang penderita asma memiliki Indeks Massa Tubuh yang tinggi seperti pada obesitas serta pada IMT yang terlalu rendah (kurus). Penelitian ini bertujuan untuk mengetahui perbedaan kualitas tidur pasien asma terkontrol sebagian pada kategori indeks massa tubuh (IMT).Metode: Penelitian ini bersifat observasional analitik dengan pendekatan cross sectional. Penelitian ini dilakukan di Balai Besar Kesehatan Paru Masyarakat (BBKPM) Surakarta pada bulan Oktober – Desember 2018 dengan melibatkan 75 sampel. Pengumpulan data dilakukan melalui wawancara terpimpin dan pengukuran IMT pada pasien asma terkontrol sebagian. Data dianalisis secara statistik dengan uji Fisher’s Exact Test.Hasil: Pada pasien asma terkontrol sebagian dengan IMT normal, kualitas tidur baik lebih banyak terjadi dibandingkan kualitas tidur buruk yaitu sebesar 57,14%, sedangkan pasien dengan IMT kurus dan gemuk memiliki kualitas tidur buruk lebih dominan dengan persentase berturut-turut sebesar 100% dan 75%. Hasil uji Fisher’s Exact Test kualitas tidur pasien asma terkontrol sebagian pada kelompok IMT kurus dan normal adalah signifikan secara statistik (p=0,004), kelompok IMT normal dan gemuk signifikan secara statistik (p=0,013), serta kelompok IMT kurus dan gemuk tidak signifikan secara statistik (p=0,173).Kesimpulan: Terdapat perbedaan kualitas tidur pasien asma terkontrol sebagian pada kategori Indeks Massa Tubuh (IMT).

One-third of the Indonesian population uses herbs for alternative medicine empirically. One of them is Kapulaga (Amomum cardamomum) which known as a spice and traditionally used for the treatment of rheumatic, fever, cough, sore throat, and mouth odor. The clinical use of herbs must be supported by scientific evidenced-based and its safety profile. The risk of exposure to a substance in humans can be identified through the toxicity tests on animals. The liver histopathological structure is one of the parameters of the acute toxicity test. This study to determine the acute toxicity of Kapulaga seeds extract (Amomum cardamomum) based on the liver histopathological structure of Wistar rats. The sample selection based on inclusion and exclusion criteria in the OECD 420 guideline. The research consisted of a preliminary and the main test. One rat was used in the preliminary test with an initial dose of cardamom seed extract 300 mg/kg BW and followed by a maximum dose of 2000 mg/kg BW after 48 hours. The main test used 10 rats that were randomly divided into control and treatment groups. Based on the result of the preliminary test, the treatment group was given a single dose of cardamom seed extract 2000mg /kg BW, whilst the control group was given distilled water. Observations of any toxic signs or dead were conducted every 30 minutes in the first 4 hours and continued once per day until 14thday. Assessment of the degree of liver damage was done using the liver damaged scoring and compared using the Mann Whitney test (α = 0.05). The average liver damage score of control and treatment groups is 0.96 ± 0,856 and 0.96 ± 0,604, respectively, and did not show any statistically significant differences (p>0,05). Kapulagaseeds (Amomum cardamomum) had no acute toxic effect based on the liver histopathological structure of Wistar rats.

Tympanic membrane perforation is a significant clinical concern that can lead to hearing impairment and recurrent ear infections. This study aims to review the roles of Interleukin-1 beta (IL-1β), Fibroblast Growth Factor (FGF), fibroblasts, keratinocytes, granulation tissue, and collagen density during the wound-healing phases of the tympanic membrane.A Systematic Journal Review was conducted by analyzing studies retrieved from PubMed, Scopus, ScienceDirect, and Google Scholar databases published between 2020 and 2025. Of the 400 records screened,, 10 studies met the inclusion criteria. The findings revealed that IL-1β plays a key role in the inflammatory phase by modulating immune responses and recruiting healing cells. FGF stimulates fibroblast and keratinocyte proliferation, which are essential for extracellular matrix (ECM) remodeling and re-epithelialization. Moreover, granulation tissue formation and collagen deposition are critical determinants of structural integrity and healing quality. Overall, tympanic membrane repair requires synergistic interactions among molecular mediators, cellular components, and biomaterial support to optimize tissue regeneration. These findings provide a scientific basis for developing more effective regenerative and tissue-engineering strategies for middle ear therapy.
