A faunistic survey of aphids was carried out in the centre of Iran. Aphids were collected and identified from 14 host plants. Thirteen species, belonging to 3 families (Aphididae, Pemphigidae, Lachnidae) were recorded. According to collected data, the family Aphididae had the highest number identified species of the 3 families. The greatest diversity of aphids was found on plants of the family Rosaceae. All the species have been reported for Iran from other provinces in the past; however, they are new reports for Yazd province. Nine species of ladybirds were also identified. 相似文献

Background:
In previous studies, the neuroprotective effect of 17β-estradiol in diffuse traumatic brain injury has been shown. This study used ICI 182,780, a non-selective estrogen receptor antagonist, to test the hypothesis that the neuroprotective effect of 17β-estradiol in traumatic brain injury is mediated by the estrogen receptors.Methods:
The ovariectomized rats were divided into eight groups. Brain injury was induced by Marmarou’s method. Estrogen was injected 30 minutes after traumatic brain injury, and ICI 182,780 was injected before traumatic brain injury and also before estrogen treatment. In one group only ICI 182,780 was injected. The brain water content and Evans blue dye content were measured 24 and 5 hours after traumatic brain injury, respectively. The neurologic outcomes and intracranial pressure were assessed before, 4, and 24 hours after traumatic brain injury.Results:
Brain water content and Evans blue content were less in estrogen-treated group comparison to vehicle group. ICI 182,780 eliminated the effects of estrogen on brain edema and brain blood barrier permeability. Intracranial pressure was increased significantly after trauma, and estrogen decreased intracranial pressure at 4 and 24 hours after traumatic brain injury in comparison to vehicle. This inhibitory effect was also eliminated by treatment with ICI182,780. ICI 182,780 also inhibited the estrogen induced increase in neurologic outcomes following traumatic brain injury. However, the use of ICI 182,780 alone had no neuroprotective effect after traumatic brain injury.Conclusion:
The results suggest that classical estrogen receptors have probably a role in the neuroprotective function of estrogen following traumatic brain injury.Key Words: Estrogens, Intracranial pressure (ICP), Brain edema 相似文献4.

The objective of this study was to investigate the effect of feeding different levels of ruminally protected methionine and choline on the incidence of physiological and metabolic disorders, production, and some of the reproductive indices of Holstein dairy cows. Forty Holstein dairy cows in their first and second lactation were used from 4‐week pre‐partum through 20‐week post‐partum and randomly assigned to receive one of the following treatments: 18 g/day of rumen‐protected methionine (RPM), 60 g/day of rumen‐protected choline (RPC), 18 g/day of RPM + 60 g/day of RPC, and neither supplement (control). The treatments significantly affected services per conception and open days of lactating dairy cows (p < 0.05), but did not affect significantly on days to first oestrus and number of pregnant cows. RPM + RPC‐fed cows had the lowest open days, days to first oestrus and services per conception compared with other groups. The effect of treatments was significant on the incidence of metabolic and physiological problems except for foot/leg problems. Cows fed RPM+RPC had the lowest health problems compared with other groups (p < 0.05). Results indicate that the supplementation of RPM and RPC can improve reproductive performance and health status of dairy cows. 相似文献

This study was conducted to evaluate the changes in serum metabolic factors of over conditioned pregnant rats treated with silymarin in food restriction condition. Sixty pregnant Wistar rats were divided into five equal groups. All rats received high energy diet before treatments. Control group were fed ad libitum (Non-FR). Rats in other groups received 50% of the food intake of Non-FR group and served as food-restricted (FR) groups. Three of five FR groups received 150, 200 and 400 mg kg(-1) silymarin, respectively (FR-150, 200, 400). Another FR group (FR-Con) and the Non-FR group did not receive any silymarin. Glucose, triglyceride, LDL and HDL cholesterol, total cholesterol, thyroid hormones and cortisol were measured in serum. All factors were significantly different between groups except free-T4 and T4. Serum glucose concentrations in FR-150 and 200 and Non-FR groups were lower than FR-Con and FR-400. Silymarin significantly increased serum triglycerides, LDL cholesterol and cholesterol contents in FR groups. The highest levels of these factors were noted in 200 mg silymarin-treated group. HDL cholesterol was highest in FR-Con; meanwhile FR-200 group had the lowest HDL cholesterol. Serum cortisol decreased in treated and untreated FR groups except FR-150 group. Free-T3 and T3 concentrations in FR-400 and FR-Con groups were higher than the other silymarin treated groups. In conclusion our results indicate that 200 mg kg(-1) of silymarin in Wistar rats is the best dosage to achieve metabolic benefits. Silymarin has positive effects on lipid metabolism and can modulate serum triglyceride and cholesterol concentrations in food restriction condition. Also, the present findings suggest that silymarin under food restriction situation exerts a decreasing effect upon peripheral conversion of T4 to T3. 相似文献

The possibility of manufacturing rubberwood and kenaf (Hibiscus cannabinus L.) stem medium density fibreboard (MDF) panels at different pressure and resin content were investigated. The effect of mechanisms of interacted independent variables (resin content and pressure) on MDF properties was analyzed. The board performance was evaluated by measuring internal bond (IB) strength, modulus of rupture (MOR), modulus of elasticity (MOE), water absorption (WA) and thickness swell (TS). The test results were statistically analyzed by using response surface method (RSM) to determine the significant independent variables that influenced MDF properties. A mathematical simulation or response surface models were developed to predict the MDF properties (MOR, MOE, IB, WA and TS). The obtained results showed that MDF density and all interactions between the experimental variables were significant factors that influenced the mechanical properties of MDF. At 8 bar and 14 % resin content, the MDF recorded WA of 83.12 % and TS of 20.2 %. It can be inferred that two parameters (resin content and pressure) had positive effect on physical and mechanical properties of MDF. We concluded that resin content show more significant effects on MDF manufacturing as compared to pressure parameters. 相似文献

Currently, mesenchymal stem cells (MSCs) are used in veterinary clinical applications. Bone marrow and adipose tissue are the most common sources of stem cells derived from adult animals. However, cord blood which is collected non‐invasively is an alternative source of stem cells other than bone marrow and adipose tissue. Moreover, high availability and lower immunogenicity of umbilical cord blood (UCB) haematopoietic stem cells compared to other sources of stem cell therapy such as bone marrow have made them a considerable source for cell therapy, but MSCs is not highly available in cord blood and their immunogenicity is poorly understood. In this study, the cells with spindle morphology from 7 of 9 bovine UCB samples were isolated and cultured. These mesenchymal stromal cells were successfully differentiated to osteocytes, chondrocytes and adipocytes. In addition, Oct‐4 and SH3 were determined by RT‐PCR assay. It is the first report of isolation, culture, characterization and differentiation of bovine umbilical stem cells. 相似文献

The aim of this study was to investigate the role of acute-phase protein concentration and metabolic status in the establishment and resistance of clinical endometritis (CE) and subclinical endometritis (SE) in dairy cows. We also characterised the treatment-related changes in the concentration of acute-phase proteins and metabolic variables in dairy cows affected by CE and SE. Cows of the SE and CE groups presented a significantly higher β-hydroxybutyrate (BHB), haptoglobin and total sialic acid (TSA) concentrations compared with a healthy group of animals. A significantly lower serum calcium concentration, and a significantly higher serum aspartate aminotransferase activity in the CE group, were observed when compared with SE and healthy groups. The comparison of parameters before treatment indicated that cows suffering from CE or SE with lower concentrations of hepatic and inflammatory markers showed a better response to further treatment, and endometritis was not detected in the second examination. Moreover, decreased concentrations of BHB, acute-phase proteins and hepatic markers were observed after successful treatment for endometritis in CE and SE cows. The results obtained in this study suggest that improved liver function and a decrease in the acute-phase protein concentration might favour the resolution of endometritis after treatment. 相似文献
