We studied an acute and chronic oral toxicity of the extract from Ziziphus attopensis (ZA) in male and female SD rats according to the OECD guidelines. After a single oral administration of ZA 5 g/kg body weight, measurement of the body and organs, necropsy, and health monitoring were performed. The body and organ weights and behavior were not changed relative to the control rats indicating that ZA does not produce acute toxicity. The chronic toxicity was determined by oral feeding both male and female rats daily with ZA at the doses of 1, 2, 4, and 8 g/kg body weight for 180 days. Body weight changes, hematological and biochemical parameters, organ weights, gross finding, and histopathology examination were monitored during the experimental period. The results did not show any differences from the control groups. Analyses of these results with the information of signs, behavior, and health monitoring can lead to a conclusion that the long-term oral administration of ZA for 180 days does not cause chronic toxicity.

Propoxazepam, 7-bromo-5 - (o-chlorophenyl)-3-propoxy - 1,2-dihydro - 3H-1,4-benzodiazepin-2-one, in the models of nociceptive and neuropathic pain showed significant analgesic activity. In order to explore clinical potential of propoxazepam for long term human consumption, toxicology testing in laboratory animals using well-accepted international guidelines is required. Acute toxicity tests were conducted by the oral administration of 2500; 3500; 4000; 4500 and 5000 mg/kg body weight to male and female mice and rats for a period of 3, 7 and 14 day. In subacute study, male rats were administered with various doses of propoxazepam (0.9, 4.5, and 9.0 mg/kg) to evaluate its toxicity for a period of 90 days. The effect of propoxazepam on body weight gain and organ weights, food and water consumptions were analyzed. From the present study, it can be concluded that the acute (3, 7 and 14 days) and subchronic (90 days) oral administrations of propoxazepam did not produce any clinical signs of toxicity or mortality of the male and female mice and rats. These results revealed that the LD50 of propoxazepam is greater than 5000 mg/kg and it therefore, belongs to the category V of relatively non-toxic substances according to the GHS. In the acute toxicity study, neither mortality no significant change in the body weight and the relative organ weights were recorded in all treated mice and rats. Present data set revealed that there wasn`t a strong correlation between body weight with food and water consumptions. The result indicates that the oral administration of propoxazepam did not produce any significant toxic effect in mice and rats and the substance can be safely used for therapeutic use in pharmaceutical formulations.

Ficus vogelii is a medicinal plant mainly found in tropical Africa and reported to treat inflammatory complaints. This study aims to evaluate the acute and sub-chronic toxicity of the aqueous extract of Ficus vogelii stem bark in wistar rats. For acute study, aqueous extract at a single dose of 5000 mg/kg body weight was administered to female rats and observed for 14 days. In the sub-chronic study, the extract was administered daily to both sex rats at the doses of 100, 200, 400, and 600 mg/kg body weight for 28 consecutive days. Body weight was measured weekly, while hematological, biochemical, and histopathological parameters were analyzed after euthanize. Aqueous extract of Ficus vogelii at all tested doses didn’t produced any mortality or significant change on the body weight and relative weight of rats on acute and sub-chronic studies. The lethal dose 50 was estimated greater than 5000 mg/kg (DL50˃5000 mg/kg). Hematological parameters were recorded non-significant in all treated rats. Aqueous extract at 600 mg/kg significantly changed transaminases and alkaline phosphatase activities, these changes were reversible in satellites. The concentrations of bilirubin was increased at 200 and 600 mg/kg in male rats, at 100, 400 mg/kg in female rats. The levels of lipids markers didn’t changed, except the significant decrease of LDL-cholesterol. Histological examination didn’t showed any change in the architecture of the liver and kidney of rats treated compared to control. Thus aqueous extract of Ficus vogelii stem bark didn’t produced adverse effects in rats after oral acute and sub-chronic treatment.

Phytoestrogens are considered beneficial for health, but some studies have shown that they may cause adverse effects. This study investigated the effects of genistein administration during the second week of life on energy metabolism and on the circuits regulating food intake. Two different genistein doses, 10 or 50 µg/g, were administered to male and female rats from postnatal day (P) 6 to P13. Physiological parameters, such as body weight and caloric intake, were then analyzed at P90. Moreover, proopiomelanocortin (POMC) expression in the arcuate nucleus (Arc) and orexin expression in the dorsomedial hypothalamus (DMH), perifornical area (PF) and lateral hypothalamus (LH) were studied. Our results showed a delay in the emergence of sex differences in the body weight in the groups with higher genistein doses. Furthermore, a significant decrease in the number of POMC-immunoreactive (POMC-ir) cells in the Arc in the two groups of females treated with genistein was observed. In contrast, no alteration in orexin expression was detected in any of the structures analyzed in either males or females. In conclusion, genistein can modulate estradiol’s programming actions on the hypothalamic feeding circuits differentially in male and female rats during development.

BACKGROUND: Previous works indicated various pharmacology activities of bay plant (Syzygium polyanthum (Wight) Walp.), however only few studies investigated its toxicity. This work was aimed to study the subchronic toxicity of ethanol extract of this plant.METHODS: White Wistar rats were divided into 4 groups and were treated with 2% of Arabic gum (PGA) suspension, 1000 mg/kg of body weight (BW), 400 mg/kg of BW and 100 mg/kg of BW, respectively. The animals were observed on their body weight, hematology, clinical biochemistry parameters, organ index and histopathology.RESULTS: Flavonoids, tannins, polyphenols, saponins, quinones, monoterpenes and sesquiterpenes were detected in dried leaves and ethanol extract of bay plant. An increase of body weight in male and female groups treated with dose 100 and 400 mg/kg BW compared to controls, was observed. Moreover, there was an increase of white blood cell (WBC) in male and female groups treated with S. polyanthum extracts compared to controls, whereas a decrease of red blood cell (RBC) was observed in male groups treated with S. polyanthum extracts in dose-dependent manner compared to control. No significant changes of RBC were seen in female groups, haemoglobin values were not altered by extract treatment. Photomicrographs of liver, kidney, lungs, heart and spleen histopathology of male and female S. polyanthum extract-treated groups showed no significant alteration compared to controls.CONCLUSION: Our study revealed that S. polyanthum extracts does not show toxicity on the body weight, hematology, creatinine and serum glutamic pyruvic transaminase (SGPT), but fatty liver and necrosis are observed in female rats. This result can be beneficial for plant-based drug discovery, particularly this study provides information about the safety of S. polyanthum to be further developed as candidate of phytopharmaceutics.KEYWORDS: bay plants, salam leaves, hepatotoxicity, necrosis, SGOT, SGPT

Objective: The present study evaluated the subchronic toxicity of Lactobacillus mediated fermented Phyllanthus emblica fruit juice (FPJ) using a rat as a model system.Methods: FPJ was prepared, and estimated the changes in pH by pH meter, and microbial load by a plating method. Rats were fed with different dose of FPJ for 60 days. The changes in the body mass were noted. The blood and organs of the experimental rats were collected, after 60 days of intervention. Then, they were analyzed for the selected hematological and biochemical parameters by following standard hospital protocols.Results: The pH of FPJ after 30 days of fermentation was 3.16. FPJ was rich in probiotic Lactobacillus spp. (7.23 Log CFU per mL) without contamination. The supplementation of FPJ was not significantly affected the body weight of the experimental animals, except the female rats in posteffective dose (PED) group showed significant changes (20.83±8.49 g) compared to control (40±17.22 g). The internal organs of the rat were not affected by the FPJ supplementation. The changes observed in blood urea nitrogen, creatinine, cholesterol, triglyceride, aspartate aminotransferase; alanine aminotransferase, and alkaline phosphatase level of experimental rats, both male and female, were not significantly differed from the respective controls. The average of lymphocytes level was significantly increased in continuous dosing group of males and females. Interestingly, the increase in red blood cell and hemoglobin (HGB) were statistically significant for ED group and PED in both sexes, except for females with no effect on HGB content.Conclusion: The prepared FPJ was enriched with probiotic Lactobacillus spp. The supplementation of FPJ (up to 9 mL/kg/day) for 60 days was not significantly influenced the body weight, internal organs, biochemical and hematological parameters of experimental rats (both male and female). The results revealed that FHJ is suitable for the human consumption.

The aim of this study was to analyse the effects of different daily intakes of rapeseed bee pollen on the growth and biochemical blood serum indicators in male and female rats. A total of 40 clinically healthy male and female Wistar rats were randomly divided into four groups. In the control group (C) rats were fed a standard complete diet; in the experimental groups standard diets were supplemented with different doses of bee pollen. Treatment group T1 was given standard diet with the addition of bee pollen at a 0.3% concentration; in group T2 the addition was 0.5%; and in group T3 it was 0.75%. The experimental period lasted for 90 days. A significant effect (P < 0.05) of bee pollen on the body weight gain and feed conversion ratio of female rats was found. Significantly (P < 0.05) higher cholesterol concentration in blood serum of male rats was found in the groups with bee pollen addition (groups T2 and T3) compared to the control group. Lower triglyceride serum content in all female experimental groups (T1 and T3) was observed in comparison to the control. Higher serum cholesterol content in the experimental female rats was detected; significant differences were analysed in groups T1 and T3 compared to the control female group. Rapeseed bee pollen at concentrations of 0.5 and 0.75% positively affected the body weight gain of female rats, however, with higher feed consumption (P < 0.05). Rapeseed bee pollen reduced the triglycerides serum content in female rats and increased the cholesterol serum content in male and female rats (P < 0.05).

The objective of these repeated-dose, 8-week studies was to assess the toxicological potential of a synthetic tripeptide, L-valyl-L-prolyl-L-proline (VPP), when administered to Charles River rats and Beagle dogs. Groups of 20 male and 20 female rats were fed powdered diets containing sufficient VPP to afford daily doses of 0, 2, 8, or 16 mg/kg body weight (BW)/day. Groups of five male and five female dogs were administered 0, 2, 8, or 16 mg/kg BW/day in hard gelatin capsules. Antemortem evaluative parameters for both species included grossly observable clinical signs, body weight and food consumption, clinical pathology (hematology, clinical chemistry, urinalysis), and ophthalmological examinations. Dogs also received electrocardiographic examinations. Postmortem evaluations in both species included complete necropsy, determination of major organ weights, and histopathological examination of specimens from approximately 50 organs and tissues. All rats and dogs survived to the scheduled termination of the studies and neither species exhibited evidence of VPP effects on appetite or body weight gain/maintenance. Ophthalmic examinations revealed occasional lens clouding in rats, but this occurred in all groups and was not attributable to VPP. Some clinical pathology parameters in both species were occasionally altered, but there was no evidence that this was dose-related. Electrocardiographic examinations in dogs revealed no VPP-associated changes. Mid- and high-dose male rats (but not females) had slightly reduced mean pituitary and kidney weight parameters, whereas mid- and high-dose females had slightly increased mean uterus:body weight ratios. There were no microscopic correlates for these minor changes. Ten percent to 20 % of all female rats (but not males) exhibited corticomedullary mineralization of the kidney and gliosis of the optic nerve, and 10% to 20% of males (but not females) had thymic hemorrhage. Postmortem evaluations of dogs revealed no VPP-related effects on organ weights or either macro- or microscopic appearances of organs. The results of these studies provided no evidence of either local or systemic toxicity. Similarly, there was no evidence of neurotoxicity that might have been detected by the appearance of physical or behavioral changes during gross observations of animals. Although these results do not identify target organs for VPP toxicity, the no-observable-effect level and maximally tolerated dose are both greater than 16 mg/kg/day when administered to male and female rats and dogs for 8 consecutive weeks. Based upon food enhancement levels of VPP currently being evaluated, the resultant margin of safety (160) is substantial.
