The influence of the acute emotional stress on the activity of proteolysis and content of free sialic acids in the blood under usual conditions and after the preliminary introduction of gordox has been studied in the experiment on rabbits. It is established that the parallel rise of their levels under stress reflects degradation of glycoproteins and fragments containing sialic acids under the influence of the increased activity of proteinases. Gordox, together with the inhibition of excessive activation of proteolysis, prevents the rise of the level of sialic acids under the influence of the stress action. The conclusion is made that it is expedient to use inhibitors of proteolytic enzymes for prevention of cellular lesions in stress.  相似文献

The objectives of this study were to evaluate ovarian changes in cows with follicular ovarian cysts following treatment with either GnRH or saline. The parameters determined were the intervals from treatment to observation of a CL and from treatment to disappearance of the cyst, and the association between serum concentrations of LH, FSH and the LH/FSH ratio, before and after treatment, with the test intervals. Thirty-nine cows were identified as having follicular cysts. The GnRH treatment induced a significant increase in LH and the LH/FSH ratio. The gonadotropin response was not associated with the intervals from treatment to CL detection or to disappearance of the cyst. Survival curves for the intervals from treatment to CL detection and cyst disappearance indicate that treatment with GnRH or saline did not yield significantly different results for either parameter. The results question the efficacy of treating cystic ovarian disease with GnRH.  相似文献

The cost of radiation treatment in 1985 at an Ontario regional cancer centre accruing 2500 new patients annually was examined. The radiation treatment department was equipped with three high-energy treatment machines, a treatment simulator and a treatment planning computer and was appropriately staffed. The total average annual cost of operating one high-energy treatment machine was $668,963. Salaries and employee benefits accounted for 78% of the costs. An average of 5439 radiation treatments were given annually with each treatment machine, at a cost $123 per treatment. The cost of a curative course of radiation treatment (average of 21 treatments) was $2583, and the cost of a palliative course (average of 7 treatments) was $861.  相似文献

The purposes of the present study were to differentiate the effects of pre-surgery treatment with risedronate and post-surgery treatment with a reduced dosing frequency of risedronate on trabecular bone loss in ovariectomized rats and to determine whether post-surgery treatment with a reduced dosing frequency of risedronate would have a beneficial effect on trabecular bone loss after pre-surgery treatment with risedronate by means of bone histomorphometric analysis. The short-term experiment (6 weeks) was performed on fifty, 4-month-old, female Sprague-Dawley rats randomized into five groups (n=10 in each group). Forty rats were treated with vehicle or risedronate for 4 weeks before ovariectomy (OVX), and then treated with either vehicle or risedronate for 2 weeks following OVX (the Vehicle-OVX-Vehicle [OVX control], Vehicle-OVX-Risedronate [post-OVX treatment with risedronate], Risedronate-OVX-Vehicle [pre-OVX treatment with risedronate], and Risedronate-OVX-Risedronate [continuous treatment with risedronate] groups). The remaining 10 rats were treated with vehicle for 6 weeks, with a sham operation performed 4 weeks after the start of the experiment (the Vehicle-Sham-Vehicle [Sham control] group). During the 4 weeks prior to surgery, risedronate was administered five times a week subcutaneously at a dose of 2.5 mug /kg body weight, and during the 2 weeks after surgery, the dosing frequency was reduced to twice a week. The long-term experiment (10 weeks) had the same design as the short-term one, except that the post-OVX treatment was 6 weeks. In the short-term experiment, both pre- and post-OVX treatments with risedronate prevented trabecular bone loss of the proximal tibial metaphysis 2 weeks after OVX. In long-term experiment, however, pre- and post-OVX treatments with risedronate attenuated trabecular bone loss until 6 weeks after OVX, with pre-OVX treatment having a less pronounced effect than post-OVX treatment. In the short- and long-term experiments, pre-and post-OVX treatments had an additive effect on trabecular bone mass. The present study has shown the efficacy of pre-OVX treatment with risedronate or post-OVX treatment with a low dosing frequency of risedronate for preventing trabecular bone loss early after OVX. Post-OVX treatment with a low dosing frequency of risedronate was beneficial for attenuating trabecular bone loss late after OVX. Treatment with risedronate before OVX had an additive effect on trabecular bone mass with the treatment after OVX, suggesting that treatment with a low dosing frequency of risedronate might be acceptable for reducing OVX-induced trabecular bone loss after treatment with risedronate prior to OVX.  相似文献

测定不同光照强度下生长的辣木光合作用及与其相关生理指标日变化的结果表明,在高温和高光强的夏季,辣木的净光合速率总体趋势是:遮光35%〉自然光〉遮光65%。适当的遮光(遮光35%)后,光合速率的峰值出现晚,高光合速率的时间维持的比较长。但遮光不能过甚,当遮光达到65%时,净光合速率除在中午11:00前后外,其他时间内均处于较低水平。据此认为,在南方高温和高光强的季节里,辣木适当遮光可以提高辣木的光合速率。  相似文献

The safety and efficacy of treatment with a new pediculicide lotion, Prioderm (0.5% malathion in isopropanol), were compared with those of treatment with Kwellada (1% lindane) shampoo in a randomized trial of children with head lice. The children''s scalps were examined for live lice immediately, 7 days and 4 to 6 weeks following treatment. To determine the in-vitro ovicidal effect of treatment, samples of hair with nits were removed before and immediately following treatment; the subsequent rates of hatching were compared. No live lice were present immediately following either treatment. At 7 days after treatment 2 of the 29 children treated with Prioderm lotion and 4 of the 33 children treated with Kwellada shampoo were infested with live lice, whereas at 4 to 6 weeks after treatment 5 and 3 children respectively were infested. The initial effectiveness of treatment was 93% in the children treated with Prioderm lotion and 88% in those treated with Kwellada shampoo; however, a large difference in efficacy could have been missed owing to the small number of children in the study. Both preparations demonstrated in-vitro ovicidal activity, but neither totally abolished post-treatment hatching. No side effects were reported from either preparation. Because ovicidal activity was incomplete two treatments with the same pediculicides should be given about 7 days apart.  相似文献

A total of 447 primary root-caries lesions from 169 dental patients was studied to determine the relationships between mutans streptococci and the perceived treatment need of primary root-caries lesions. Samples of this altered dentine for microbiological culture were obtained. Lesions were classified into 5 treatment categories; soft and restore, leathery and restore, leathery and debride of caries, leathery and treat chemotherapeutically, and hard, to receive no treatment. The total numbers of mutans streptococci decreased significantly with decreased treatment need. The percentage of mutans streptococci from lesions requiring no treatment was significantly less than from lesions requiring treatment. The frequency of isolation of mutans streptococci was significantly greater from lesions requiring more treatment. Significantly more lesions containing > 102 mutans streptococci were distributed in the groups with a greater perceived treatment need or with larger dimensions occlusogingivally and/or mesio-distally or bucco-lingually or with a closer proximity to the gingival margin.  相似文献
