ABSTRACT The aim of this research was to asses the acute toxicity of ethanolic extract of malaka leaves using lethal dose 50 (LD50) on mice (Mus musculus). Twenty male mice weighing between 20-30 g were randomly divided into 4 groups (group K1-K4) of 5 mice each. All mice in group K1, K2, K3, and K4 were administered ethanolic extract of malaka leaves with the dose of 2, 4, 8, and 16 g/kg bw, respectively. Single dose of ethanolic extract of malaka leaves were given by oral gavage prior to clinical observation . The observation period was 14 days post administration, for sign of toxicity symptom, weight loss, and mortality. The result showed that no mortality was observed in the experimental animals during this study. Slight reduction of body weight was observed in group K2, K3, and K4, and no toxicity sign was found during fourteen days of observation. The LD50 of ethanolic extract of malaka leaves was higher than 16 g/kg body weight, thus, the substance was practically non toxic substance.

In order to potentially use sodium caseinate (SC) glycated with galactose (Gal) in the food industry as a new functional ingredient with proved technological and biological properties, an evaluation of oral acute toxicity has been carried out. An acute safety study with SC-Gal glycoconjugates in the Wistar rat with a single oral gavage dose of 2,000 mg/kg of body weight was conducted. The SC-Gal glycoconjugates were well tolerated; no adverse effects or mortality was observed during the 2-week observation period. No abnormal signs, behavioral changes, body weight changes, or alterations in food and water consumption occurred. After this period, no changes in hematological and serum chemistry parameters, organ weights, or gross pathology or histopathology were detected. It was concluded that SC-Gal glycoconjugates obtained via the Maillard reaction were well tolerated in rats at an acute oral dose of 2,000 mg/kg of body weight. The SC-Gal glycoconjugates have a low order of acute toxicity, and the oral 50% lethal dose for male and female rats is in excess of 2,000 mg/kg of body weight.

Lawsonia inermis is one of the most significant plants used in traditional medicine. However, many details of the dermal toxicity of L. inermis remain unknown. The objective of this study is to evaluate the in vivo acute and sub-acute dermal toxicity of ethanolic extract of L. inermis leaves. In acute experiment, a total of 20 rats were divided into four groups of five rats. A total of 30 rats were divided into five groups of six rats for the sub-acute experiment. The extract at a single dose of 2000 and 5000 mg/kg of body weight did not produce treatment-related signs of toxicity or mortality in all rats tested during the 14-day observation period. However, in a repeated dose 28-day study, the application of 500, 1000 and 2000 mg/kg of body weight/day of leaves extract revealed no significant change (p > 0.05) in bodyweight, haematological and biochemical parameters compared with the control group. Similarly, gross pathology and histopathology examinations of liver, kidneys, and skin did not reveal any morphological alteration. Overall, the results show that the close application of L. inermis leaves extract did not have any critically dangerous impact on rats. Subsequently, the concentrate may be employed for pharmaceutical plans.

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.

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.

Feral cat populations have a devastating effect on many native wildlife species. As part of a programme to evaluate improved predator control, feral cats were observed after they had ingested a polymer bait loaded with sodium monofluoroacetate (1080) 0.4-1.6 mg/g bait, equivalent to doses of 0.1-1.3 mg/kg body weight. Deaths occurred with 0.6 mg/g bait and all higher doses. With the highest dose all animals died within 24 h. An approximate oral LD50 of 0.28 mg/kg (0.07-0.49) and LD90 of 0.35 mg/kg (0.14-0.56) were calculated (with 95% confidence limits). Main symptoms were disorientation and lethargy, followed by death. A dose of 2 mg/g bait is recommended as a humane and lethal dose of 1080 for feral cats.

Abstract Objectives Several studies establish the therapeutic properties of various plants which are sometimes a source of minerals, vitamins and phytochemical compounds. However, many studies evoked potential toxic of some. In Cameroon, Crassocephalum crepidioides (C.c) is used in folk medicine to treat several diseases, but there are not much informations about its toxicity. This study evaluate its acute and sub-acute toxicity. Methods Our study was undertaken to evaluate acute and sub-acute toxicity of aqueous leaves extract of C.c. The study was conducted using the OECD guidelines about oral toxicity’s study. For acute toxicity, rats were administrated single oral dose of 5,000 mg/kg body weight (b.w) and monitored for death and weight impairment during seven days. In sub-acute toxicity, experimental rats received daily doses of 250,500 and 1,000 mg/kg b.w during 28 consecutive days. The toxics effects of the extract were assessed using anthropometric, haematological, biochemical parameters as well as histology of vital body’s organs (liver, kidneys, lungs and spleen). Results lethal dose 50 (LD50) was find to be greater than 5,000 mg/kg b.w in rats. In sub-acute toxicity, we observed significant increase of body weight, food and water consumption with the maximums of 15.14, 24.52 and 28.86% respectively at 1,000 mg/kg b.w. There was no significant change in haematological parameters. However, we observed significant change in biochemical parameters. Furthermore, structural disorders were noticed in liver and kidneys of animals treated with C.c. Conclusion Data obtained suggesting that C.c extract could be safe in single administration, but with toxic effects in repeated treatment.

The aim of the research was to study the acute and subchronic toxicity of the drug gramine in white mice. The micromycete Drechslera graminea served as the basis for the creation of the gra-mine preparation. Experiments to determine the acute toxicity of the preparation gramine were car-ried out on outbred white mice (males) weighing 18-20 grams. The drug was administered to ani-mals intraperitoneally, once in doses from 400 to 2400 mg/kg. 6 mice were used for each dose. The condition of the animals was monitored for 14 days. The dose causing the death of 50 % of the an-imals (LD50) and the absolutely lethal dose (LD100) were determined. LD50 was calculated by the Kerber method. The study of subchronic toxicity of gramine was carried out for 30 days. The drug was administered to 10 mice intramuscularly daily, in the first 4 days, gramine was injected at a dose of 0.1 LD50, and then every 4 days the dose was increased 1.5 times and finally it was 1520 mg/kg. To determine the cumulative properties of the drug in white mice, a "subchronic toxicity" test was used. The reliability of the results obtained was taken into account in accordance with the Student's t-criterion at P <0.05. As a result, it was found that the average lethal dose (LD 50) of gramine for white mice is 1334 mg/kg, LD 100 - 2400 mg/kg. Studies of the subchronic toxicity of gramine showed that doses of the drug from 133 to 450 mg/kg did not cause significant changes in the behavioral responses of laboratory mice, and a pronounced toxigenic effect began to appear at a dose of 675 mg/kg and continued to increase after a further increase in doses of gramine (1013-1520 mg/kg), while causing mortality reaching the level of 50 %. It was found that gramine with intraperi-toneal administration of the LD50 of gramine for white mice corresponds to 1334 mg/kg, which al-lows the drug to be classified as a low-toxic substance. The cumulation coefficient of gramine is 1.14, which corresponds to the group of drugs with pronounced cumulation.
