AbstractPotentilla anserina L. is not only a medicinal plant, but also a traditional cuisine. Hence, an acute toxicity study was performed to confirm its safety profile. Forty Kunming mice were randomly divided into two groups: control group and P. anserina L. extract group. Using the maximum dosage method, the P. anserina L. extract group was given the maximum dose within 12 h, equivalent to 345.6 g/kg crude drug. The control group was given distilled water. After administration, toxicity symptoms of mice were observed, body weight and food intake were recorded. After 14 days, blood was collected to measure biochemical parameters, autopsy was carried out to observe the changes of organs, and the vital organs were separated, weighed, and preserved for histopathological examination. The results showed that P. anserina L. extract group had no toxic symptoms. The activity, weight, and diet of mice were normal, and no abnormality was found in organ index, renal function, liver function, anatomical observation, and histopathological examination. Therefore, the maximum oral dosage (345.6 g/kg) of P. anserina L. was good safety. This study indicated that P. anserina L. had a large safety range and the clinical application was safe.

Background. Withania frutescens. L (W. frutescens) is a perennial woody medicinal plant belonging to family Solanaceae largely used by the indigenous population to Morocco for the treatment of disease. Objective. The purpose of this study was to investigate the chemical composition, acute, and subacute toxicity of W. frutescens extract in mice. Materials and Methods. The phytochemical composition of W. frutescens extract was determined using a gas chromatograph (GC/MS). Acute toxicity study was carried out in mice through oral administration of single doses 500 mg/kg, 1000 mg/kg, and 2000 mg/kg for 14 days. Subacute toxicity was performed with oral administration of repeated doses 500 and 2000 mg/kg/day for 28 days. Biochemical parameters (alanine aminotransferase, aspartate aminotransferase, urea, and creatinine), as well as histopathological changes potentially occurred in organs, (liver, kidney, and spleen) were evaluated. Results. The results of chromatographic analysis showed the richness of W. frutescens extract in interesting phytochemical compounds majorly constituted of bicyclo[3.1.1]heptane, 6,6-dimethyl-2-methylene-(C10H16). Regarding acute toxicity study, the results showed no clinical symptoms occurred in treated mice compared to the control group and no histological changes detected in analyzed organs of treated mice with dose put to 2000 mg/kg nor adverse effect on biochemical parameters. Conclusion. The outcome of this work showed no toxic effect of W. frutescens in mice up to dose 2000 mg/kg bodyweight. Therefore, this study could scientifically validate further traditional use with safety in the range of tested doses.

Background: The Eucalyptus globulus extractions have been used by the traditional healers to treat diseases in the study area. Our previous study revealed that the essential oil has antimicrobial and antifungal activity. This study determined phytochemical analysis, skin irritation, acute and subacute toxicity of Eucalyptus globulus essential oil in mice and rats. Methods: The phytochemicals were analyzed using GC-MS mass spectrometry. The acute toxicity study was determined at three dose levels of 1500 mg/kg, 1750mg/kg, and 2000 mg/kg. The essential oil limit test at a dose of 1000 mg/kg was administered to mice for 28 consecutive days for sub-acute toxicity study. The mice mortality, behavioral change, injury and other signs of illness were recorded once daily. Biochemical parameters were evaluated. Liver and kidney were analyzed for histopathological analyses. The 5% ointment formulation was applied to the rat skin to determine skin irritation effects. Results: The Eucalyptus globulus essential oil showed no effect on the mice at a dose of 1500mg/kg and below, but caused signs of toxicity and death at a dose of 1750mg/kg and above compared to the controls (p<0.05). The LD50 value was 1650 mg/kg. There was no significant difference (p > 0.05) in the body weights, gross abnormalities of the organs and biochemical parameters compared to the control at 1000 mg/kg subacute toxicity study. No histopathological changes were detected in the organs tested. The 5% ointment formulation did not show any abnormal skin reaction. Discussion: In the present study, the Eucalyptus globulus essential oil was comparable with other studies in terms of both chemical composition and its effects on sub-acute and topical application. Conclusion: This toxicity study demonstrated that Eucalyptus globulus essential oil is nontoxic at a relatively lower concentration.

Zerumbone- (ZER-) loaded nanostructure lipid carrier (NLC) (ZER-NLC) prepared for its antileukemia effectin vitrowas evaluated for its toxicological effects by observing changes in the liver, kidney, spleen, lung, heart, and brain tissues, serum biochemical parameters, total haemogram, and bone marrow stem cells. The acute toxicity study for ZER-NLC was conducted by orally treating BALB/c mice with a single dose with either water, olive oil, ZER, NLC, or ZER-NLC for 14 days. The animals were observed for clinical and behavioral abnormalities, toxicological symptoms, feed consumption, and gross appearance. The liver, kidney, heart, lung, spleen, and brain tissues were assessed histologically. Total haemogram was counted by hemocytometry and microhematocrit reader. Bone marrow examination in terms of cellular morphology was done by Wright staining with bone marrow smear. Furthermore, serum biochemical parameters were determined spectrophotometrically. Grossly all treated mice, their investigated tissues, serum biochemical parameters, total haemogram, and bone marrow were normal. At oral doses of 100 and 200 mg/kg ZER-NLC there was no sign of toxicity or mortality in BALB/c mice. This study suggests that the 50% lethal dose (LD50) of ZER-NLC is higher than 200 mg/kg, thus, safe by oral administration.

Abstract. Ahaddin AY, Budiarti S, Mustopa AZ, Darusman HS, Triratna L. 2021. Short Communication: Acute toxicity study of plantaricin from Lactobacillus plantarum S34 and its antibacterial activity. Biodiversitas 22: 227-232. Lactobacillus plantarum S34 belongs to the Lactobacilli class produces a bacteriocin called plantaricin. Bacteriocins are well known as active compounds that inhibit bacterial growth. This study was conducted to determine the antimicrobial activity of plantaricin S34 and its safety profile in the ddY mouse animal models. Plantaricin 34 from the crude extract was identified using Tricine SDS-PAGE. Antimicrobial activity was observed using disk diffusion against EPEC K1.1, S. aureus, S. typhosa, S typhimurium, and Proteus sp. The safety assessment showed that crude extract of plantaricin S34 did not cause any abnormalities to experimental mice even after being administrated with 5000 mg/kg BB. The identification of plantaricin S34 showed an active molecule at 7.34 kDa and had an activity to inhibit the pathogens used in this study. The blood analysis showed that the hematological and biochemical blood properties were in the normal range. Histopathological examination showed no damage to the intestine, liver, and kidneys. Thus, the crude extract of plantaricin S34 is active as an antimicrobial agent without any toxicity effects.

The current study was carried out to investigate the sub-acute toxicity of 3-O--D-glucopyranosyl-(24)-ethylcholesta-5,22,25-triene, a steroidal glycoside isolated from the flowers of Alangium salviifolium Wang on Long Evan’s rat. After intra-peritoneal administration of the compound at a dose of 300 μg/rat/day for 14 consecutive days, no mortality or significant changes in body weight or behavior were observed. The blood samples of the rats were examined for hematological and biochemical parameters which were statistically insignificant when compared to that of the control group. All the vital organs showed normal histopathological architecture (heart, lungs, liver and kidney) in comparison to the control group. This preliminary investigation demonstrate that the compound is safe at dose of 300 μg/rat/day for 14 consecutive days. But acute, sub-chronic and chronic toxicity evaluations as well as clinical trials need to be done.

Abstract Galactomannans from Caesalpinia pulcherrima (GM-CP) and Delonix regia (GM-DR) are being pointed as potential therapeutic agents, but systematic evaluations on their acute toxicity are yet to be reported. In order to evaluate the occurrence of systemic toxicity, groups of three female rats received oral GM-CP or GM-DR (300 mg kg-1), whereas the control group received vehicle. Since lethality was absent, other groups received doses of 2,000 mg kg-1, which also did not cause lethality. Collection of organs and blood samples were done at day 14. Dermal toxicity of the galactomannans was also evaluated (2,000 mg kg-1, n=3 per group), as well both mechanical hypernociception and inflammatory cell influx after administration of GM-CP or GM-DR via intra-articular route (200 µg, n = 5 per group). At the routes and doses employed, both galactomannans did not evoke physiological / behavioral changes or skin / joint inflammation. Since the LD50 was not inferior to 2,000 mg kg-1, both galactomannans are in the class 5 of the Globally Harmonized System for Classification and Labelling of Chemicals.

Potato tocosh is a naturally processed potato for nutritional and curative purposes from traditional Peruvian medicine. The aim of this study was to investigate the acute and sub-acute toxicity of tocosh flour (TF). For sub-acute toxicity, TF was administered orally to rats daily once a day for 28 days at doses of 1000 mg/kg body weight (BW). Animals were observed for general behaviors, mortality, body weight variations, and histological analysis. At the end of treatment, relative organ weights, histopathology, hematological and biochemical parameters were analyzed. For acute toxicity, TF was administered orally to mice at doses of 2000 and 5000 mg/kg BW at a single dose in both sexes. Body weight, mortality, and clinical signs were observed for 14 days after treatment. The results of acute toxicity showed that the median lethal dose (LD50) value of TF is higher than 2000 g/kg BW but less than 5000 mg/Kg BW in mice. Death and toxicological symptoms were not found during the treatment. For sub-acute toxicity, we found that no-observed-adverse-effect levels (NOAEL) of TF in rats up to 1000 g/kg BW. There were statistically significant differences in body weight, and relative organ weight in the stomach and brain. No differences in hematological and biochemical parameters were observed when compared with the control group. For sub-acute toxicity, histopathological studies revealed minor abnormalities in liver and kidney tissues at doses of 5000 mg/Kg. Based on these results, TF is a traditional Peruvian medicine with high safety at up to 1000 mg/kg BW for 28 days in rats.

Abstract Background The leaves of Jatropha tanjorensis have been found to have important application both in traditional medicine and as an edible vegetable in Nigerian soups. It is popularly employed in Nigeria for the treatment of anemia, diabetes, and malaria. The dearth of information on its toxicity prompted this study. Mice were administered single oral doses of 10, 100, 1000, 1600, 2900, and 5000 mg/kg b.wt (n = 3/group) of the extract and were observed for 24 h for any sign of toxicity and mortality in the acute toxicity study. For the sub-acute toxicity study, doses of 100, 200, and 400 mg/kg b.wt of the extract were administered to experimental rats (n = 6/group) for 28 days after which the assessment of hematological and biochemical parameters, as well as liver and kidney histology was conducted post-treatment. Body weight of the animals was also taken weekly. Results The result showed that percentage weight gain decreased as the dose of extract increased. The haematological and biochemical parameters showed that the extract had no toxic effect on experimental animals, though there was a non-significant dose-dependent decrease in WBC. The extract also showed potential to cause hepatotoxicity at the highest dose. Conclusion Though the median lethal dose of the plant extract suggests relative safety of the plant material, consuming large amounts over a prolonged time may need to be discouraged to avoid potential damage to vital organs such as the liver.

Nypa fruticans Wurmb. (nipa palm) sap, locally known as air nira or tuak, is a sweet natural beverage in Malaysia with antioxidant potency beneficial for human health. However, nypa sap lacks scientific attention with no toxicity study has been established. Therefore, this study was performed to evaluate the acute toxicity of nypa sap in the female Sprague Dawley rats. Twenty-five female rats were randomly divided into one control group and four treated groups. Treated groups were orally administered with doses of 5, 50, 300, and 2000 mg/kg of nypa sap, while the control group had received normal saline solution. The animals’ vital signs and mortality were recorded daily at an interval of 30 min and continued up to 14 days. Their blood samples and organs were harvested for toxicity analysis to assess liver and kidney function, lipid profile, and full blood count. The acute toxicity test via measurement of the biochemical and haematological parameters had shown that there was no significant difference between the treated and control groups. However, the blood glucose level in the treated groups (at higher doses of 300 and 2000 mg/kg, respectively) was significantly decreased. A similar trend was recorded for mean corpuscular volume (MCV) albeit in the treated group of 50 mg/kg doses. Histopathological examination of the organs showed no signs of abnormality in both treated and untreated groups. Overall, the results showed that consumption of nypa sap is potentially safe with no acute toxic effect on the laboratory rat models.
