Dominant lethal studies were conducted in male and female mice with α‐asarone, the active hypolipidaemic component of Guatteria gaumeri Greenman, by per os sub‐chronic treatment (10 and 20 mg/kg, 5 days/week, for 8 weeks) and subsequent mating. α‐Asarone did not produce germinal mutations in either males or females. Epididymal sperm examination of male mice immediately after treatment failed toreveal any alteration in sperm count on shape. No significant alterations were observed in testicular or epididymal weights or testicular histology. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

The antiimplantation, antifertility and reproductive toxicity potentials after ingestion of aqueous and ethanolic extracts of Salvia fruticosa leaves have been investigated in male and female rats. The ingestion of 200, 400 and 800 mg/kg of aqueous or 400 mg/kg of ethanolic extracts of S. fruticosa from day one to day six of pregnancy by female rats did not cause pregnancy failure. However, the ingestion of an ethanolic extract reduced the number of viable fetuses and increased the number of resorptions in the pregnant rats. The ingestion of aqueous extract (800 mg/kg) or ethanolic extract (400 mg/kg) of S. fruticosa for 30 consecutive days by adult female rats had no effect on the occurrence of pregnancy. However, the ingestion of these extracts reduced both the number of implantations and viable fetuses and increased the number of resorptions in the pregnant females. The ingestion of aqueous extract (800 mg/kg) or ethanolic extract (400 mg/kg) of S. fruticosa for 30 consecutive days by adult male rats had no effect on the number of females impregnated by these males. However, the number of implantations and viable fetuses were reduced in females impregnated by males which ingested either aqueous or ethanolic extracts of S. fruticosa, whereas the number of resorptions was increased in females impregnated by males administered either aqueous or ethanolic extracts of S. fruticosa. On the other hand, the prenatal exposure of male and female rat offspring to 400 mg/kg ethanolic extract of S. fruticosa had no effects on the timing of testicular descent and vaginal opening, respectively. It would appear from these experiments that the ingestion of S. fruticosa may produce adverse effects on the fertility of male and female rats. 相似文献

A study was conducted in hamsters to determine if artichoke leaf extract (ALE) could lower plasma total and non‐HDL cholesterol by increasing fecal excretion of neutral bile acids and sterols. Sixty‐four Golden Syrian hamsters (8 week old) were fed control diet or a similar diet containing ALE (4.5 g/kg diet) for 6 weeks. No significant changes for total cholesterol, HDL, non‐HDL cholesterol triglycerides or fecal neutral sterols and bile acids were found after 21 days for ALE‐fed animals compared with controls. But after 42 days, ALE‐fed male hamsters had significantly lower total cholesterol (15%), non‐HDL cholesterol (30%) and triglycerides (22%) and female hamsters fed ALE showed reductions of 15% for total cholesterol, 29% for non‐HDL cholesterol and 29% for triglycerides compared with controls. Total neutral sterol and bile acids concentrations increased significantly by 50% and 53% in fecal samples of ALE fed males, and 82.4% and 25% in ALE fed females compared with controls. The ALE lowered hamster plasma cholesterol levels by a mechanism involving the greater excretion of fecal bile acids and neutral sterols after feeding for 42 days.

Brain is highly susceptible to oxidative damage due to its high utilization of oxygen and rather poorly developed antioxidative defense mechanism. Free radicals formation is greatly augmented during ionizing radiation exposure, which causes damage in cerebellum responsible for locomotor activity. Amaranthus paniculatus (Linn.) having high content of beta-carotene (about 15 mg/100g), ascorbic acid, Vitamin C and folate, may prove efficient antioxidants. To evaluate its antioxidative efficacy, healthy Swiss albino mice from an inbred colony were selected and divided into three groups having equal number of male and female in each group. All of these animals were initially trained in Hebb William's Maze, model D(1). After initial training of 10 days, two groups were supplemented with methanolic extract of A. paniculatus (Linn.) at a dose of 600 and 800 mg/kg bw per day, respectively for 15 days. One group without any treatment served as normal. It has been observed that mice, supplemented with extract took lesser time to reach goal than normal (without any treatment). Furthermore after supplementation of Amaranthus, followed by exposure to 9 Gy of gamma radiation by 60Co beam therapy unit, the survived mice took lesser time to reach to their goals than those without plant extract. Control mice (not supplemented with AE extract) showed continuous decline in their learning performance. Mice of Control group died within 12 days after exposure. Irradiated males try to recover from 10th day onwards but they died up to day 12. But in Experimental mice (AE treated), after initial decline in learning ability after exposure, recovery was noticed and not only this 70% of them survived beyond the observation period. Besides male mice showed faster learning ability as compared to females in all groups. After irradiation too, males took lesser time to reach to goals. Learning in all the groups before exposure has been much faster in between 9 and 15 days. After radiation, however it was followed by a sudden spurt and delayed learning response up to 12 days. Recovery was greater in males than females in treated groups. Recovery was greater in males of 600 mg/kg bw per day than other groups. Learning has been almost at the same level from 14th day onward, which indicates that both the dose levels have been found equally effective. 相似文献

Adult BALB/c mice, genetically resistant to HSV-1 i.p. infection, were inoculated intraperitoneally with 1000 PFU of HSV-1 and treated by the same route with four consecutive doses of Melia azedarach L. aqueous green leaves extract (MA) each containing 80 antiviral units against HSV-1 replication in Vero cells. Mice were injected 1 day and 6 h before infection and 1 and 2 days after infection. Mortality among untreated 45 day old female and male mice was around 35% for both sexes, whereas MA treatment increased mortality to 95% in females and to 50% in males. Virus was isolated from brains of treated animals. Enhanced susceptibility to HSV-1 infection upon treatment with MA extract was also observed in male mice 25 days old, before hormonal maturation, indicating that the impairment of natural resistance to HSV-1 infection is sex-linked. Treatment with MA extracts did not interfere with established specific immune protection nor with the induction of immune response to HSV-1. Virus was recovered from peritoneal exudate cells only in MA-treated animals. The abrogation of natural resistance of inbred mice to i.p. HSV-1 infection by pretreatment and early administration of the plant extract indicates that the in vivo expression of immunomodulating activities on receptor cells interfered with its potent antiviral activity displayed in vitro against HSV-1 replication. © 1998 John Wiley & Sons, Ltd. 相似文献

Coriolus versicolor, which is known as Yun Zhi, is one of the commonly used Chinese medicinal herbs. Recent studies have demonstrated its antitumor activities on cancer cells which led to its widespread use in cancer patient. However, little toxicological information is available regarding its safety. The present study evaluated the potential toxicity of Coriolus versicolor standardized water extract after acute and subchronic administration in rats.Materials and methods
In acute toxicity study, Coriolus versicolor water extract was administered by oral gavage to Sprague-Dawley (SD) rats (6 males, 6 females) at single doses of varying concentrations 1250, 2500 and 5000 mg/kg. In subchronic toxicity study, the extract was administered orally at doses of 1250, 2500 and 5000 mg/kg/day for 28 days to male and female SD rats respectively. General behavior, adverse effects and mortality were determined throughout the experimental period. Haematological and biochemical parameters, relative organ weights and histopathological were evaluated at the end of the experiment.Results
There were no mortality and signs of toxicity in acute and subchronic toxicity studies. In the single dose acute toxicity and repeated dose 28-day subchronic toxicity studies, there were no significant difference in body weight, relative organ weight, haematological parameters, clinical chemistry, gross pathology and histopathology between treatment and control groups.Conclusions
Coriolus versicolor water extract did not cause remarkable adverse effect in SD rats. The oral lethal dose of Coriolus versicolor water extract is more than 5000 mg/kg and no-observed-adverse-effect level (NOAEL) of the extract for both male and female rats is 5000 mg/kg per day for 28 days. 相似文献11.

Stem bark extracts of Terminalia superba Engl. and Diels and Canarium schweinfurthii Engl. are used in Africa for the treatment of various ailments, including diabetes mellitus. The anti-diabetic effects of the methanol/methylene chloride extracts of the stem barks on streptozotocin (STZ)-induced diabetes were evaluated on male rats. Through the subcutaneous route, diabetes was induced using 60 mg/mL of streptozotocin. After 2 days, the rats received, by gavage, 150 mg/kg and 300 mg/kg of extract daily for 14 days. At 300 mg/kg, the two extracts (Terminalia superba and Canarium schweinfurthii), significantly showed at least 67.1% and 69.9% reduction in blood glucose level, respectively, while insulin (three units) given subcutaneously and once daily, had 76.8% reduction compared to diabetic untreated control rats. Similarly, the weight gains were 6.6% and 4.9%, respectively, and were comparable to the normal rats, whereas, diabetic untreated rats lost 14.1% body weight. Still with the same dose, there was 68.5% and 58.5% (p < 0.001) significant decrease in food consumption and 79.7% and 64.0% (p < 0.001) in fluid intake by diabetic rats treated with the respective plant extracts. The insulin-treated rats showed 56.4% and 75.8% decrease in food and fluid intake compared to an augmentation for diabetic control rats, 43.0% and 383.8%, respectively, at the end of the second week of experimentation. These results showed that the plant extracts can reverse hyperglycemia, polyphagia and polydipsia provoked by streptozotocin, and thus, they have anti-diabetic properties. 相似文献

Since the use of Nelumbo nucifera stamens in herbal medicines as well as in cosmetic products are highly prevalent in Thailand and increasing worldwide, acute and subchronic toxicity studies to confirm the safe use of Nelumbo nucifera stamens are warranted.Aim of the study
Acute and subchronic oral toxicity studies of Nelumbo nucifera stamens extract in rats were performed in the present study in order to evaluate its safety.Materials and methods
In acute toxicity study, Nelumbo nucifera stamens extract was administered by oral gavage to Sprague-Dawley rats (5 males and 5 females) at a dose of 5000 mg/kg. In subchronic toxicity study, the extract at doses of 50, 100, and 200 mg/kg/day were given orally to groups of rats (6 rats/dose/sex) for 90 consecutive days.Results
The extract at a dose of 5000 mg/kg produced no treatment-related signs of toxicity or mortality in any of the animals tested during 14 days of the study. In the repeated dose 90-day oral toxicity study, there was no significant difference in body weight between the control and all treatment groups with the exception of the body weight of the female group treated with 200 mg/kg/day of the extract which was statistically significantly less than that of its control counterpart on day 90 but the percent weight changes of both groups were almost similar. Some statistically significant differences in hematological and biochemical parameters as well as in some internal organ weights of both male and female rats treated with the extract at the highest dose were observed. However, no abnormality of internal organs was observed in both gross and histopathological examinations.Conclusions
These results suggest that the oral lethal dose of Nelumbo nucifera stamens extract for male and female rats is in excess of 5000 mg/kg and the no-observed-adverse-effect level (NOAEL) of the extract for both male and female rats is considered to be 200 mg/kg/day. 相似文献16.

The genus Rumex and related species such as Rheum and Polygonum are widely used as medicinal herbs and foods. They contain anthraquinones (AQ) such as emodin and chrysophanol as active ingredients, and there is concern about the toxicity of these compounds. This study evaluated the chronic effects of Rumex patientia seed aqueous and ethanolic extracts, in male and female rats separately, on organ weights and over 30 haematological, biochemical and histological parameters, immediately after 14‐week administration and after a further period of 15 days without drug treatment. Adverse changes were associated with long‐term AQ administration, and these focussed on the liver, lung and kidney, but after 15‐day convalescence, most had reverted to normal. In general, male rats appeared to be more susceptible than female rats at similar doses. The water extract produced no irreversible changes, which may reflect the lower dose of the AQ constituents or the presence of different ancillary compounds, and supports the traditional method of extracting Rumex seeds with water. In conclusion, ethanolic extracts of R. patientia caused irreversible pathological changes at very high doses (4000mg/kg), but lower doses and aqueous extracts produced either non‐significant or reversible changes. Long‐term administration of high doses of AQ extracts over a long period of time should be avoided until further assurances can be given, and given other existing reports of reproductive toxicity, should be avoided altogether during pregnancy.
