Summary In the present study, the effect of varied gossypol (GOSS) amounts was investigated on blood parameters, the digesta pH, villus height, villus width, and crypta depth, width of duodenum, jejunum and ileum. A total of one hundred eight Ross 308 male broilers were fed with four diet groups as follows: no gossypol (control), gossypol rate 62 mg/kg (GOSS 62), gossypol rate 124 mg/kg (GOSS 124) and gossypol rate 186 mg/kg (GOSS 186). The effect of used gossypol amounts on blood parameters was not found to be statistically significant. Increases in digesta pH values of jejunum and ileum with GOSS 186 diet group were found to be statistically significant. The results also indicated that, except duodenum villus height, there was no statistical difference effect of GOSS on epithelial cell thickness, villus height, villus width, crypta depth and crypta width of the duodenum, jejunum and ileum. There have been no clearly negative effects of higher gossypol amounts up to 186 mg/kg diets on these parameters. 相似文献

Chestnut blight caused by Cryphonectria parasitica is a serious disease of Castanea sativa in the Black Sea region of Turkey. During disease surveys, dieback and decline symptoms were observed on trees without apparent blight and ink disease symptoms. Black necroses, similar to those caused by Phytophthora infections, were noted on some of the chestnut coppices and saplings in one nursery in Ordu and led to an investigation into this disease complex. Only symptomatic plants showing dieback symptoms were investigated. Soil samples together with fine roots were collected from two directions, north and north‐east, approximately 150 cm away from the main stems. Phytophthora spp. were baited with young chestnut leaves. Three Phytophthora spp., P. cambivora, P. cinnamomi and P. plurivora, were identified from 12 soil samples collected from 73 locations, while from the nurseries, only P. cinnamomi was obtained. Phytophthora cinnamomi was the most common species, obtained from seven locations in five provinces and from four nurseries having similar symptoms mentioned above in different locations. Phytophthora cambivora and P. plurivora were less frequently obtained, from three to two stands, respectively. Phytophthora cinnamomi and P. cambivora were the most aggressive species when inoculated at the stem base on 3‐year‐old chestnut saplings, killing six saplings of eight inoculated in 2 months. The three Phytophthora species were first recorded on chestnut in Black sea region of Turkey with the limited samples investigated in a large area about 150 000 ha chestnut forest. 相似文献

Evaluation of analgesic, anti-inflammatory and hepatoprotective effects of lycorine from Sternbergia fisheriana (Herbert) Rupr 总被引:1,自引:0,他引:1
The present study reports the potential antinociceptive, anti-inflammatory and hepatoprotective activities of lycorine from Sternbergia fischeriana (Herbert) Rupr. (Amaryllidaceae). Lycorine was evaluated on mice by using acetic-acid induced writhing and tail-flick tests. Lycorine exhibited stronger inhibition than aspirin in acetic-acid induced abdominal stretching at 1.0 mg/kg dose. Lycorine also showed antinociceptive activity at 1.0 mg/kg dose in tail-flick test. The anti-inflammatory activity of lycorine was not found to be significant at dose of 0.5 mg/kg. However, at doses of 1.0 mg/kg and 1.5 mg/kg, i.p. showed a significant reduction with 53.45% and 36.42%, respectively in rat paw oedema induced by carrageenan against the reference anti-inflammatory drug indomethacin (3 mg/kg, i.p.) (95.70%). The ED50 of lycorine was determined as 0.514 mg/kg. Hepatoprotective activity of lycorine on carbon tetrachloride (CCl4) induced acute liver toxicity following biochemical parameters were also evaluated. Rats were treated with lycorine at doses of 1.0 mg/kg and 2.0 mg/kg, i.p. Results of biochemical tests were confirmed by histopathological examination. Lycorine exhibited significant hepatoprotective effect at dose of 2.0 mg/kg i.p. dose. 相似文献

A better understanding of regenerative growth is very important for the development of new potential strategies. Recently, the pineal secretory product melatonin was shown to stimulate the regeneration process. In this study, we carried out an experimental investigation of tail regeneration in young adult lizards, Ophisops elegans macrodactylus Berthold, 1842, addressing the role of melatonin on the regeneration process. Lizards were divided into three groups: constant light-exposed control group (n = 13), constant dark-exposed group (n = 15) and parachlorophenylalanine (p-CPA) treatment group exposed to constant light (n = 15). Using a tail autotomy procedure, the effects of p-CPA treatment on connective tissue together with neural tissue and vascular tissue in regenerating tail in lizards were investigated. p-CPA (400 microg/kg body mass) was injected from day 0 to 30 days after autotomy. p-CPA treatment produced a significant increase in the length of the regenerated tail compared with light-exposed control and dark-exposed lizards. Total collagen content was found to be higher in p-CPA-treated animals in comparison with other groups. Histologically, a higher percentage of connective tissue and vascular tissue and a lower percentage of neural tissue were found in the regenerated tails of the p-CPA-treated lizards. Importantly, the percentage of neural tissue in lizards in the dark-exposed animals was higher than that in animals of both light-exposed and p-CPA treatment groups. Thus, it is clear that p-CPA has a stimulatory influence on fibroblast collagen production and vascularization of the regenerated tail in the lizards. Furthermore, it seems that the neural regeneration process was markedly enhanced in lizards exposed to continuous darkness. Based on the results of our study, it is suggested that melatonin may be an active factor that speeds up the rate of tail regeneration in lacertilians. 相似文献

Extensive use of gas chromatographic analysis of the volatile and non-volatile components of sheep urine and sheep vulvovaginal secretions at different stages of the oestrous cycle has not succeeded in identifying the putative oestrus-indicating pheromone produced by the ewe. However the putative pheromone is probably not a low molecular weight alcohol, diol, phenol, amine, amide, aldehyde, ketone, fatty acid or steroid. 相似文献

1. The present study was conducted to evaluate the relationship between slaughter ages and carcase characteristics of Japanese quail.
2. Chicks were slaughtered at 5, 6, 7, 8 and 9 weeks of age. Carcase yield, carcase parts weight, weight of liver, heart, gizzard and alimentary tract were obtained. Protein, fat, dry matter and ash contents of meat were analysed for each sex.
3. Body weight and eviscerated weight were affected by age. Age had no significant effect on the weight of liver, alimentary tract, gizzard and heart. Age had first and second order polynomial effects on breast weight and relative leg weight. Meat compositions of leg and breast were significantly affected by age. 相似文献

Acute pancreatitis (AP) is a well known complication of organophosphate (OP) poisoning and the true incidence is unknown; but, may be more common than clinically suspected. Previous studies suggest that Diphenhydramine (DPH) may be useful as an alternative or adjunctive therapy in OP poisoning. The aim of this experimental study was to investigate whether DPH could prevent or diminish pancreatic damage caused by OP poisoning as defined by histologic findings, and serum interleukin 10 (IL-10) and tumor necrosis factor alpha (TNF-α) levels. Twenty-four Sprague- Dawley rats were divided into equal three groups. Group 1 did not receive any agent during the experiment. Group 2 received 0.8 g/kg fenthion subcutaneously followed by 3 ml/kg normal saline intramuscularly, 30 min later. Group 3 received 0.8 g/kg fenthion subcutaneously, followed by 30 mg/kg DPH intramuscularly, 30 min later. Twenty-four hours later, pancreatic tissues were excised and blood samples were taken. After blood samples were taken by cardiac puncture, the animals were sacrificed. Treatment with DPH significantly decreased the serum TNF-α and increased the serum IL-10 levels. DPH significantly reduced pancreatic damage, including edema, inflammation, vacuolization and necrosis, as determined by pathologic scoring. The present study show that DPH decreased the severity of OP induced AP in rats. This effects may be related to a decrease of TNF-α level and increase of IL-10 level. 相似文献
