Abstract Background The unopened buds of the fruit of Harungana madagascariensis is used in the treatment of anaemia and skin diseases in traditional medicine. Hence, this study aims to scientifically evaluate the effects of oral administration of the fruit extract of Harungana madagascariensis on haematological, biochemical and histological parameters in Wistar rats. Methods Phytochemical screening of the ethanol fruit extract of H. madagascariensis was carried out. Acute toxicity test was done using Lorke’s method. Sub-acute toxicity studies were done using 24 rats of both sexes which were randomized into four groups of six rats each. Animals in groups A, B, C were administered with the extract at doses of 250, 500 and 1000 mg/kg, respectively while group D animals were given distilled water (5 mg/kg) and served as the control group. All administrations were done through the oral route for 30 consecutive days. Body weights of the animals were taken weekly during the study. The animals were sacrificed under diethyl ether anaesthesia and blood samples collected for evaluation of haematological (red blood cell, haemoglobin, packed cell volume and white blood cell) and biochemical (alanine transferase, alanine aminotransferase, alkaline phosphatase, urea, creatinine, total cholesterol and total protein) parameters. Histological examination was conducted on the liver and kidney of the animals. Results Preliminary phytochemical screening of the extract revealed the presence of alkaloids, anthraquinones, steroidal nucleus, saponins, carbohydrates, flavonoids, and tannins. Acute toxicity test showed that the LD50 was greater than 5000 mg/kg. There was no statistically significant (P < 0.05) difference in the RBC, HB, PCV and WBC of the extract treated groups when compared to the control group. There was however, a statistically significant (P < 0.05) difference in the creatinine level of the 500 mg/kg extract –treated group and the control. There was no statistically significant (P < 0.05) difference in other biochemical parameters of the extract treated groups and the control group except for a marginal increase in the total protein in the group treated with 1000 mg/kg of the extract (60 g/L) compared with control (54.80 g/L). Histopathological examination showed alterations in the morphology of the liver and kidney in extract treated groups as compared to the control groups. Conclusion The findings have revealed that the ethanol fruit extract of H. madagascariensis should be used with caution especially during prolonged usage as the histology showed it has nephrotoxic and hepatotoxic potentials. Further studies will be done to establish the effects of the extract on white blood cells.

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.
