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

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.

In recent years many waterways in Slovenia have been subjected to an increased loading with pesticides due to intensification of agriculture. The most widely used herbicides are atrazine and alachlor and they were detected in some rivers and even in ground water. Therefore the effects of atrazine and alachlor on selfpurification processes were investigated. The basic selfpurification processes studied were biodegradation of organic substances and photosynthesis and growth of algae. The inhibiting effect of pesticides on the process of biodegradation of organic pollutants was evaluated by the use of laboratory river model and mathematical modelling. The harmful impacts of pesticides on aquatic autotrophic organisms were assessed by measurement of net assimilation inhibition (24-h acute toxicity test) as well as growth inhibition - chlorophyll- a content (72-h chronic toxicity test) of algae Scenedesmus subspicatus. The results obtained demonstrate that atrazine and alachlor in concentrations found in our rivers have practically no effect on biodegrading heterotrophic organisms, while their adverse effect on algae is quite considerable.

This article use the Sulphide Isobutene (T321), Five Sufides Dialkyl(RC2540) and Star of Phosphorus(P110) as the additives,Neopentyl Polyol Ester(NPE) and mineral oil N32 as base oil. Compound above additives and base oil for the four levels. A sample: adding 4% T321 additive in NPE. B sample: adding 4% T321 additive in N32. C sample: adding 4% RC2540 additive in NPE. D sample: adding RC2540, T321 and P110 additives in NPE (all is mass fraction). The oral acute toxicity test, eye mucous stimulation test, skin hypersensitive test, soaking tail toxicity tests were conducted in above samples. The test results show that. The mineral oil, it’s not only toxic then synthetic oil but also has a poor lubricating ability compare with the same percent additive in synthetic oil. In oral acute toxicity test, eye mucous stimulation test, skin hypersensitive test, soaking tail toxicity tests, Toxic reaction of mineral N32+4%wt Sulphide Isobutene (T321) obviously from other oil samples.
