Changes in the content of carbohydrate-containing proteins in the liver of rats chronically exposed to pesticides combined with total gamma irradiation

A study was made of the chronic effect of pesticides, within a wide range of doses, combined with whole-body gamma-irradiation, on the content of carbohydrate-containing proteins of rat liver. The extent to which disturbances in the carbohydrate-containing protein metabolism were manifest was shown to depend upon dose and time of action of the damaging factors. As determined by certain parameters, the combined effect of pesticides and gamma-radiation at the biochemical level was additive, and it was more than additive as estimated by a number of other tests.

Evaluation on the combined effect of Sesamin and Schisandra extract on blood fluidity

Several studies have demonstrated a link between blood viscosity and various forms of liver dysfunction. Therefore, we investigated the effect of liver protective herbal materials, Sesamin combined with extract of Schisandra chinensis berry (Schisandra) for its potential to improve blood fluidity in humans. Ten human subjects were recruited to study the effect of sesamin combined with schisandra extract (SCH) for two weeks on blood viscosity. Blood fluidity was measured as the transit time for 100mul of heparinized whole blood to pass through a micro-channel array setup at baseline, 1 week and 2 weeks. For safety assessment, blood biochemistry, hematology and urine analysis were taken at baseline, 1 week and 2 weeks after SCH administration. No safety concern and adverse effects were observed during the 2-week continuous intake period. Intake of SCH reduced blood passage time by 9.0% and 9.7% at 1 and 2 weeks, respectively. In conclusion, this pilot clinical study indicates that the combined administration of sesamin with schisandra extract could improve blood fluidity after 1 week of oral intake and this effect was sustained up to 2 weeks.     

Effect of metronidazole and local irradiation of the tumor on paramagnetic metal complexes of the liver and tumor tissues

A study was made of changes in the intensity of the ESR signals in tissues of sarcoma-37 and liver of mice after radiation of the tumor, administration of metronidazole, and after the combined effect of the two factors. The most pronounced changes in the ESR signals were induced by metronidazole. An appreciable increase in the content of nitrosyl complexes in the tumor was noted after the combined effect of metronidazole and radiation which was indicative of the radiation-induced formation of a large number of metronidazole anion-radicals in the tumor.     

培美曲塞联合顺铂治疗晚期非小细胞肺癌的临床疗效观察

目的:探讨培美曲塞联合顺铂治疗晚期非小细胞肺癌(NSCLC)的临床疗效。方法:随机选取我院肿瘤科晚期NSCLC患者177例,随机将其分为3组,培美曲塞联合顺铂治疗(PP组)72例,多西他赛联合顺铂治疗(DP组)53例,吉西他滨联合顺铂治疗(GP组)52例,比较三组治疗方法的临床疗效与不良反应之间的差异,根据临床疗效将PP组分为有效组与无效组,分析培美曲塞联合顺铂治疗晚期NSCLC的影响因素。结果:PP组疾病控制率(DCR)与客观有效率(ORR)均显著高于GP组(均P0.05);PP组与DP组近期疗效之间的比较无显著差异(均P0.05)。PP组的药物毒副作用均显著优于DP组与GP组(均P0.05)。PP组的中位生存期显著高于DP组与GP组(均P0.05),在无吸烟、腺癌与IV期晚期NSCLC患者中,培美曲塞联合顺铂治疗有效率更高。结论:培美曲塞治疗晚期NSCLC的疗效佳,与多西他赛相当并显著优于吉西他滨治疗,药物毒副作用小,且受吸烟状况、病理类型与临床分期影响。     

植物-微生物联合修复毒死蜱污染的土壤

本试验以毒死蜱污染土壤为研究材料,利用降解菌DSP-A分别与高丹草、紫花苜蓿、多花黑麦草进行联合修复,探讨了植物-微生物联合修复毒死蜱污染土壤的效果,以及影响联合修复的因素,结果表明,植物．微生物联合修复的效果优于单一的植物修复及单一的微生物修复效果。与DSP—A菌群较合适的植物是高丹草,该组合对毒死蜱的降解率达到96．44％,其次是多花黑麦草。研究了微生物数量、植株密度以及土壤湿度对联合修复效果的影响,结果表明,DSP．A菌菌液稀释倍数越大,联合修复的效果越差。植株密度对联合修复的影响,主要表现为对植物根系生长的影响。植株密度越大,对生存环境的竞争越激烈,植物根系的生长越不好。除了紫花苜蓿外,高丹草和多花黑麦草根系的生长均受到影响。高丹草种植密度为12株／盆时,与DSP—A菌的联合修复效果最好,多花黑麦草则为10株／盆。土壤湿度是影响联合修复的重要因素,不仅影响植物的生长,对微生物的生长也有影响。土壤湿度过大,造成土壤的含氧量降低,不利于植物根系和好氧细菌的生长,从而影响土壤中农药的降解。土壤湿度过小,容易造成植株缺水,根系生长和微生物的生长。高丹草与DSP．A菌、多花黑麦草与DSP—A菌联合修复最适浇水量都为20mL／d,紫花苜蓿与DSP—A菌联合修复最适浇水量都为15mL／d。

The dynamics of the morphological changes in the tissues after the subcutaneous administration of vaccines against Q fever]

The comparative study of the dynamics of morphological changes in tissues of guinea pigs after the subcutaneous injection of chemical, live and combined vaccines against Q fever during the period from 12 hours to 90 days was made. All vaccines under study were shown to produce a pronounced local damaging effect. Two periods were tentatively discriminated in the dynamics of changes: the early phase (till 48 hours) and the late phase (days 2-90). At the early stage the most pronounced changes were registered after the injection of the combined vaccine. At the late phase the use of the chemical and combined vaccines was accompanied by the appearance of secondary hemorrhages into newly formed connective tissue. Starting from day 30, practically no deviation from the normal state of tissues were registered at the site of injection.

Teratogenic effect of ketamine and cocaine in CF-1 mice

Pregnant CF-1 mice were used to study the teratogenic effect of ketamine and cocaine, alone and in combination. The dose of ketamine was 50 mg/kg and that of cocaine was 20 mg/kg, given intravenously (tail) once daily (these doses of ketamine and cocaine are comparable to doses used by addicted humans). Treatment was started from day 6 to day 15 of gestation, and dams were sacrificed on day 18. There were significant decreases in the fetal weight and length in the combined group. Skeletal defects such as incomplete ossification of skull bones and vertebrae were observed in both the cocaine and combined group, compared with the control. An increased frequency of cerebral and abdominal hemorrhages as well as hydrocephalus and hydronephrosis was observed in the combined group. This study showed that fetal exposure to ketamine and cocaine in combination was more teratogenic than each drug alone in CF-1 mice.

双歧杆菌协同TIL细胞体内杀瘤活性的研究

本研究应用从小鼠Ｓ１８０癌性腹水分离诱导的ＴＩＬ癌内注射与活的双歧杆菌腹腔内注射共同治疗荷Ｓ１８０实体瘤小鼠,结果表明单用ＴＩＬ和ＴＩＬ合用ＩＬ－２早期抑瘤效果,能延缓肿瘤的发生和发展,而晚期抑瘤效果尚不及单用双歧杆菌组。ＴＩＬ与双歧杆菌、ＴＩＬ、双歧杆菌及低剂量ＩＬ－２,荷瘤早、晚期抑瘤效果均较好,且毒副作用低,表明双歧杆菌有可能通过刺激机产生内源性ＩＬ－２维持ＴＩＬ的生物学活性从而协同ＴＩＬ细     

Anticonvulsant drugs for management of pain: a systematic review.

OBJECTIVE--To determine effectiveness and adverse effects of anticonvulsant drugs in management of pain. DESIGN--Systematic review of randomised controlled trials of anticonvulsants for acute, chronic, or cancer pain identified by using Medline, by hand searching, by searching reference lists, and by contacting investigators. SUBJECTS--Between 1966 and February 1994, 37 reports were found; 20 reports, of four anticonvulsants, were eligible. MAIN OUTCOME MEASURES--Numbers needed to treat were calculated for effectiveness, adverse effects, and drug related withdrawal from study. RESULTS--The only placebo controlled study in acute pain found no analgesic effect of sodium valproate. For treating trigeminal neuralgia, carbamazepine had a combined number needed to treat of 2.6 for effectiveness, 3.4 for adverse effects, and 24 for severe effects (withdrawal from study). For treating diabetic neuropathy, anticonvulsants had a combined number needed to treat of 2.5 for effectiveness, 3.1 for adverse effects, and 20 for severe effects. For migraine prophylaxis, anticonvulsants had a combined number needed to treat of 1.6 for effectiveness, 2.4 for adverse effects, and 39 for severe effects. Phenytoin had no effect on the irritable bowel syndrome, and carbamazepine had little effect on pain after stroke. Clonazepam was effective in one study for temporomandibular joint dysfunction. No study compared one anticonvulsant with another. CONCLUSIONS--Anticonvulsants were effective for trigeminal neuralgia and diabetic neuropathy and for migraine prophylaxis. Minor adverse effects occurred as often as benefit.

摘要 目的：探讨院前急救联合绿色通道模式对行急诊经皮冠状动脉介入术（PPCI）的急性心肌梗死（AMI）患者救治效果和术后不良心血管事件的影响。方法：选取2017年1月~2019年6月期间我院收治的行PPCI术的AMI患者200例,采用随机数字表法将患者分为对照组（n=100）和研究组（n=100）,对照组患者予以传统急诊模式,研究组患者予以院前急救联合绿色通道模式,比较两组患者救治效果、满意度、确诊时间、心肌再灌注治疗时间、住院时间、术后不良心血管事件。结果：研究组抢救时间、急救反应时间、确诊时间、心肌再灌注治疗时间以及住院时间均短于对照组（P<0.05）。研究组治疗后的临床总有效率高于对照组（P<0.05）。研究组的总满意度为91.00%（91/100）,高于对照组的76.00%（76/100）（P<0.05）。研究组术后不良心血管发生事件发生率为2.00%（2/100）,低于对照组的17.00%（17/100）（P<0.05）。结论：行PPCI术的AMI患者给予院前急救联合绿色通道模式,救治效果显著,可有效提高患者满意度,减少术后不良心血管事件的发生率。     

Modification of the radiosensitivity of bacteria by glutaraldehyde

A study was made of the combined effect of ionizing radiation and various concentrations of glutaric aldehyde (0.00125, 0.0025, 0.5, and 1 per cent) on viability of bacteria differing in a cell wall structure, radiosensitivity, and activity of DNA repair system. The combined effect of the two factors was shown to produce an effect of superadditive enhancement of bacterial cell death. The synergism was more pronounced in highly radiosensitive bacteria.
