This research aims to evaluate the safety of ethanolic extract of Acalypha hispida (A. hispida) leaves with acute toxicity test using 15 female rats strain Sprague-Dawley. A single dose of different doses of extract (2, 4, 8, and 16 g/kg body weight) was administrated orally, and theobservation was conducted for 14 days. The results revealed that the ethanolic extract of A. hispida leaves was relatively harmless (LD50 16 g/kg BW), did not affect body weight, and did not show clinical signs of toxicity during the observation periods. The parameters of blood serumbiochemistry of all extract-treated groups (alanine aminotransferase, aspartate aminotransferase, creatinine, and urea) did not change significantly  compared to the control group. The histological observation of the liver showed a significant increase in eosinophilic cytoplasm and basophilic nuclei at all doses. However, the ethanolic extract of A. hispida leaves did not significantly affect glomerulus/Bowman’s capsule ratio, glomerular cell density, and the proportion of normal cell tubule. In conclusion, the ethanolic extract of A. hispida leaves was relatively harmless with LD5016 g/kg BW and seems to be safe in low doses (2 g/kg BW).

Areca (Areca catechu L.) seeds ethanolic extract (AE) exhibits antiproliferative activity and induces apoptosis on T47D and MCF-7 cells. This study aimed to verify AE safety using acute toxicity test to support its development as chemopreventive agent. Male Sprague Dawley Rat (Rattus norvegicus) age 8 weeks divided into five groups, one group of control treated with 0.5% CMC-Na only and four groups for treatment. Single dose in oral administration was done to test animal with various dose of AE starts from lowest dose to highest dose expected toxic to all of test animal (0.1; 0.72; 5.36 and 10 gram/kgBW). Observation was done during 24 hours and continued for 14 days. The observation criteria were toxic symptoms, appearance and mechanism of toxic effect and pathology of vital organ. Histopathology analysis of some vital organs was done with Haematoxyllin&Eosin (H&E) staining. Toxic effect did not appear either on treatment groups or control group. Treatment of single dose of areca ethanolic extract, even in highest dose, did not cause the death of the animals. Therefore, observation extended to 14 days and terminated by necroption of the animals. All of groups did not show histopathological alterations in microscopic observation. Category of the potential toxicity of AE is practically non-toxic, ie 10 g/kgBW. The result shows the safety of areca seed ethanolic extract which is important for its development as chemopreventive agent.Keywords: Areca catechu, acute toxicity, rat

Pre-clinically, the potential of Eleutherine americana Merr. as antioxidant has been studied, but it’s safety level of its safety has not been widely known. Safety level of ethanolic extract of E. americana Merr leaves (EEEaL) can be detected by acute toxicity test using OECD 425. The aim of this study was to investigate the acute toxicity of EEEaL as the guideline of its safe dose for therapy. This test was performed through OECD 425 (Up and Down Procedure) method with two doses (2000 and 5000 mg/kgbw) of EEEaL administration orally which observed for two weeks toward Wistar rats. The results of the test dose showed no toxic symptoms and they did not cause death in the test animals. Single dosage up to 5000 mg/kgbw also did not show any symptoms of toxicity, and did not cause weight loss until the 14th day of test. The LD50 value of EEEaL is more than 5000 mg/kgbw, suggesting that the plants is practically non toxic according to Loomis classification. Phytochemical screening showed that EEEaL contains compounds such as alkaloids, flavonoids, triterpenoids, steroids, and saponins. Dhaka Univ. J. Pharm. Sci. 18(2): 171-177, 2019 (December)

Objective: This study aimed to investigate the hematologic profile of Wistar rats in the acute toxicity test of Cogon grass roots ethanol extract (CGEE). Methods: Cogon grass roots were dissolved in 70% ethanol. An acute toxicity test was conducted based on The National Agency of Drug and Food Control of the Republic of Indonesia. Five female rats in the treatment group were administered a single high dose of 5000 mg/kg body weight (BW) of CGEE in 200 μl of 0.5% carboxymethyl cellulose (CMC), and the 5 female rats in the control group were administered 200 μl of 0.5% CMC. After 14 d, blood samples were collected, and 18 hematologic parameters were measured with a hematology analyzer. Statistical analyses were performed to compare the parameters between the two groups with the independent t-test for normally distributed data and the Mann Whitney test for non-normally distributed data. Results: None of the hematologic parameters in the treatment group significantly differed from those in the control group after 14 d of observation (P>0.05). Conclusion: A single high dose of 5000 mg/kg BW of CGEE did not change the hematologic profile of Wistar rats. These results indicate that CGEE does not have an acute hemotoxic effect, at least for hematologic parameters.

Hepatic Transaminase

The herb frequently used as spices or remedies in the Indonesian community, with the seed as the most common part is kapulaga (Amomum cardamomum). According to earlier evidence, this possessed antibacterial, antifungal and several biological properties, reduced blood glucose and atherogenic parameter, and is developed as standardized herbal cures. However, the application of herbal medicine requires validating evidence of safety and effectiveness, including toxicity tests, particularly in clinical settings. The target organs in this comprised hepar, due to the role in several drug metabolism. This study aimed at discovering the safety profile of kapulaga seed extract based on the hepatic transaminase enzyme (SGOT and SGPT) level, by conducting an acute toxicity test in Winstar rats. Also, this was implemented with the OECD 420 Fixed-Dose Procedure, and the preliminary test employed 300 mg/kg BW dose followed by a maximum single quantity (2000 mg/kg BW) of kapulaga. The main test was executed by a separation into control and treatment groups of 5 rats each. Therefore, a single dose of 2000 mg/kg BW kapulaga seed extract was administered to the treatment group, while the control group received standard pellets and water ad libitum. The blood from orbital vein was acquired on day 14, and SGOT and SGPT were subsequently assessed by an enzymatic-photometric method. Also, this data was analyzed using an independent sample t-test, and the mean of SGOT in both groups were 116.92±22.35 and 98.02±16.38 (p=0.17), with 58.72±8.79 and 47.64±7.30 (p=0.06) as SGPT respectively. Therefore, there was no statistical difference, and no acute toxicity signs were discovered. The maximum dose was not toxic and did not result in poisonous symptoms or alter hepatic transaminase enzyme (SGOT and SGPT) in rats.Keywords: Amomum cardamomum, kapulaga, acute toxicity, SGOT, SGPT  Uji Toksisitas Akut Ekstrak Biji Kapulaga (Amomum cardamomum) Berdasarkan Kadar Enzim Transaminase Hepar Tikus WinstarAbstrakKapulaga (Amomum cardamomum), merupakan salah satu herbal Indonesia yang secara umum dimanfaatkan sebagai rempah-rempah maupun obat, terutama bagian biji. Beberapa bukti sebelumnya menunjukkan bahwa kapulaga memiliki berbagai aktivitas biologis seperti antibakteri, antijamur, dan sudah dibuktikan mampu menurunkan glukosa darah dan parameter arterogenik. Bukti tersebut mendukung pengembangan kapulaga sebagai obat herbal terstandar. Penggunaan obat herbal terutama di klinik harus didukung dengan adanya bukti keamanan maupun efektivitasnya termasuk uji toksisitas. Hepar merupakan salah satu target organ dari uji toksisitas karena perannya yang penting pada metabolisme sebagian besar obat. Penelitian ini bertujuan untuk menilai profil keamanan ekstrak biji kapulaga melalui uji toksisitas akut menggunakan tikus Winstar berdasarkan kadar enzim transaminase hepar (SGOT dan SGPT). Uji toksisitas akut berpedoman pada OECD 420 Fixed Dose Procedure. Uji pendahuluan menggunakan ekstrak biji kapulaga dosis 300 mg/kg BB dan diikuti dengan dosis tinggi 2000 mg/kg BB yang diberikan secara tunggal. Uji utama dilakukan dengan membagi tikus ke dalam kelompok kontrol dan perlakuan, masing-masing kelompok terdiri atas 5 tikus. Berdasarkan hasil uji pendahuluan, uji utama menggunakan dosis tunggal 2000 mg/kg BB untuk kelompok perlakuan, sedangkan kelompok kontrol hanya mendapatkan pelet dan air secukupnya. Pada hari ke-14, darah dari vena orbital diambil, lalu kadar SGOT dan SGPT diukur menggunakan metode enzymatic-photometric. Independent sample t-test digunakan untuk menilai data rata-rata kadar SGOT dan SGPT dari kedua kelompok. Rata-rata kadar SGOT pada kelompok kontrol dan perlakuan sebesar 116,92±22,35 dan 98,02±16,38 (p=0,17), sedangkan rata-rata SGPT sebesar 58,72±8,79 dan 47,64±7,30 (p=0,06). Perbedaan rata-rata SGOT dan SGPT pada kedua kelompok tersebut secara statistik tidak bermakna dan tidak ditemukan tanda toksisitas pada semua hewan coba. Ekstrak biji kapulaga dosis maksimal 2000 mg/kg BB tidak toksik pada hepar tikus karena tidak menimbulkan tanda toksisitas maupun mengubah enzim transaminase hati (SGOT dan SGPT). Kata kunci: Amomum cardamomum, kapulaga, toksisitas akut, SGOT, SGPT

Abstract: Toxicity Test Of Acute Industrial Waste Water On Tilapia Fish (Oreochromis Niloticus). The sasirangan industrial liquid wastes containing high ammonia and high pH when discharged into the receiving water body without treatment will result in changes in water quality and even the death of aquatic biota so that an acute toxicity test is necessary. This study aims to determine the value of LC50 from waste sasirangan against tilapiaI. This research used the experimental method of Post Control Only Control Group Design design. Samples taken as much as 100 liters of waste in one industry sasirangan existing in the city of Banjarmasin. Concentrations of the sasirangan waste solution to be used in the acute toxicity test are: 4, 8, 12, 16 and 20%. Parameters studied include ammonia, DO, pH, and temperature. To determine the value of LC50 using probit analysis. The results showed that LC50 for exposure time 24, 48, 72 and 96 hours were 14.73%, 10.21%, 8.26%, and 7.35%, respectively. The results of the analysis show that pH and ammonia content of industrial effluent sasirangan affect the death of tilapia fish. This research is hoped that the sasirangan industry does not dispose of its waste directly to the water body but needs to process it first. For further research it can complement the untested parameters such as BOD, COD, and TSS that affect fish survival.

TiO2 was a photocatalyst that used to the most common product because of the high efficiency. TiO2 (P-25, commercial nanomaterial product) is the most typical photocatalyst product and TiO2 (GST) was a sludge recycling product. This study was reported to evaluate an acute toxicity of TiO2 (P-25 and GST) according to OECD test guideline 402 and 423 in Sprague-Dawley (SD) female rats via route of oral and dermal. There was investigated the lethal dose (LD50), and mortality, clinical signs, body weight changes and gross findings were continually monitored for 14 days following the single administration. After administration, TiO2 (P-25) was calculated that LD50 was considered to be a dose of over 2000 mg/kg body weight for both different route of exposure, and TiO2 (GST) was the same. Other items were no observed an adverse effect between P-25 and GST; no mortality and clinical signs, accidental body weight loss, no gross findings. On the basis of the above results, the toxicity of the GST was almost equal to that of the commercial product, P-25 and there was no toxicological evidence.
