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.

The aim: to determine the effect of a preparative form of an antiemeric agent based on maduramycin and nicarbazine on the body of white rats and broiler chickens under the conditions of a subacute experiment. Materials and methods. The formulation based on maduramycin and nicarbazine was administered to rats and broiler chickens with feed for 28 days. One control and three experimental groups were formed for the experiment: Group I – animals received a complete diet without admixture of the formulation (control group), Group II – animals that were administered the formulation (by the amount of active substances) at a dose of 5.0 mg / kg, III – 25.0 mg / kg and IV – 50.0 mg / kg of feed, respectively. In order to establish the toxic effect of the formulation on the body of experimental birds on 7, 14, 28 days of the experiment and 7 days after discontinuation of the formulation, 5 heads from each group were killed under light ether anesthesia, blood samples were taken for hematological and biochemical studies. Results. During the study of the general clinical condition of rats and broiler chickens of the experimental groups, no significant changes in behavior and appearance were detected, compared with the control. Hematological parameters of broiler chickens it was found that the receipt of the formulation with feed at doses of 5, 25 and 50 mg/kg body weight, causes a decrease in hemoglobin and an increase in hematocrit in broiler chickens on day 7 of the experiment. It was found that the changes are reversible, on the 28th day of the experiment the value of these indicators was within the physiological norm. In the study of hematological and biochemical parameters of rats, it was found that the receipt of the formulation with food in doses of 25.0 and 50.0 mg/kg for 28 days, causes a decrease in hemoglobin and increase hematocrit, total protein, albumin, creatinine and urea in male rats on the 7th day of the experiment. Conclusions. Under conditions of repeated oral administration of the preparation mixture to rats and poultry at doses of 5, 25 and 50 mg/kg body weight in the absence of clinical signs of poisoning, insignificant fluctuations in hematological and biochemical parameters were identified

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.

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.

The study was conducted to assess the effects of sweet potato leaves, roselle calyces and beetroot tubers on body weight, selected hematological and biochemical parameters in broiler chickens. Eighty four (84) broiler chickens aged four weeks were randomly assigned into six groups of 14 chickens each. The first group (G0) remained as untreated control while the other groups were the treated groups which received 25% of ground sweet potato leaves (G1), rosella calyces (G2), beetroot tubers (G3) and their mixtures (G4 and G5) for 28 days. Following inclusion of these different vegetables, blood samples were collected and analyzed for selected hematological and biochemical parameters on day 0, 7, 14, 21 and 28. Results showed that consumption of the three vegetables caused significant decreases (p < 0.05) in body weight, serum glucose and cholesterol. On the other hand, hemoglobin concentration, packed cell volume (PCV) and total white blood cell (WBC) counts were shown to increase significantly (p < 0.05) compared to the control group. It is concluded that the hypoglycemic and hypocholesteremic effects in chickens following consumption of the three vegetables together with their positive effects on PCV and WBC counts are important qualities which can be utilized in the management of conditions such as obesity, diabetes mellitus, hyperlipidemia and cardiovascular diseases (atherosclerosis and coronary disease) in humans. Further studies in other animals are recommended.

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.

ABSTRACT Reducing the mortality rate is of a great economic importance for pig farming. Therefore, it is necessary to define the conditions in the farrowing unit based on the performance of the piglets, and specific hematological and biochemical parameters. Therefore, the aim of this paper is to examine the importance of using skin moisture absorbent and its influence in preventing hypothermia, which causes great economic losses in pig production. The experiment was set up on a commercial farm in Serbia and included 92 pigs divided into the experimental and control group. Body temperature values, body weight and blood parameters were monitored. The obtained values indicate that there is a significantly positive correlation of body temperature change and body weight values, and body temperature showed a significantly higher increase in the experimental group compared to the control group. The results obtained from hematological and biochemical parameters provide a clearer picture of the metabolic processes in piglets in the farrowing unit and can be used to further improve pig production and as a complement to genetic enhancement.
