Pain relieve after impacted wisdom teeth extraction dependent on the drug therapy

Purpose of this study was to compare the effects of combined therapy using nonsteroid anti-inflammatory analgetics and corticosteroids, and the effects of the mono-therapy with same drugs for post-operative pain after surgical removal of the impacted mandibular third molar. The study was completed at the Department of Oral Surgery and at the Department of Dental Medicine of the Public Institute Health Center Zenica in Zenica. The research included 60 patients divided into 3 groups using random selection, including both sexes. Age range was between 18 and 45 years. All participants came without any pain or other inflammatory symptoms at the time of oral surgical intervention. Two medicaments were prescribed after the impacted tooth removal: 15 mg of nonsteroid anti-inflammatory analgesic drug (Meloxicam, Bosnalijek, BiH) and 32 mg Methylprednisolone (corticosteroid, Bosnalijek, BiH). Both medicaments were applied per os, according to schedule determined by the research protocol. The level of post-surgical pain was evaluated by the 1-10 visual analog scale (VAS). One way ANOVA was made with Tuckey post-hoc tests. Statistically significant difference (p < 0.05) was found between the group treated with mono therapy and the group treated with combined therapy. Application of monotherapy using only corticosteroids or only nonsteroid anti-inflammatory pain-killers was less effective compared to the combined therapy with both medicaments after surgical removal of the impacted mandibular third molar.

SEASONAL VARIATION IN THE EFFECT OF A FIXED DOSE OF HEPARIN ON ACTIVATED CLOTTING TIME IN PATIENTS PREPARED FOR OPEN-HEART SURGERY *

We investigated the effect of an injected bolus of 5 mg kg^- heparin at one circadian stage (08:30 to 11:00) on blood coagulation during different months of the year. Activated clotting times (ACTs) were assessed before and 5 min after heparin dosing to ensure extracorporeal circulation during open-heart surgery. The ACT data of 1083 presumably day-active Turkish patients (816 men and 267 women, mostly older than 46 years) who underwent coronary bypass surgery between 08:30 and 11:00 in the years from 1994 to 1997 were analyzed for annual rhythmicity. The ACT values obtained just before and 5 min after heparinization were subjected to cosinor analysis using a 365.25-day period to assess seasonality in basal ACT level and heparin effect. A small-amplitude annual rhythm with a wintertime peak was documented in the morning ACT in the group of 1083 patients. Rhythms of similar magnitude and staging were also detected in heparin effect on ACT in the 1083 patients and in subgroups categorized by gender. Circannual rhythmicity in the heparin effect on ACT was also documented in the elderly (≥ 45 years old), but not young (18-45 years old) patients. The annual mean effect of heparin on the ACT was statistically significantly greater in younger than older patients. The relatively low-amplitude circannual rhythm in heparin effect on ACT (∼10% of the annual mean) is not viewed as being meaningful in patient preparation for bypass surgery for the 5 mg kg^-1 level of heparin dosing.

低分子肝素钙对小血管损伤术后血液流变学影响的临床研究

目的：观察应用低分子肝素钙如何提高断指再植成活率的作用机制,为临床更好的应用低分子肝素钙提供理论基础。方法：通过临床随机对照试验设计,以30例断指再植患者为研究对象,30例健康成人为参照对象。观察30例断指再植患者术前术后不同时段血液流变学指标的变化。结果：断指患者受伤至术后72h血液流变学指标均明显升高,与对照组比较有显著差异（P〈0.01）。低分子肝素钙可以显著降低断指再植患者的血液粘度,改善血液不利于断指成活状态,提高断指成活率,降低其坏死率、致残率。结论：低分子肝素钙,毒副作用小,为防治断指再植术后并发症的一种良药,为临床断指成功再植提供了一种较为理想的治疗方法。     

肝素处理山羊精子体外获能的研究

系统研究了作用浓度、时间和温度以及输卵管上皮细胞和卵丘细胞对肝素处理山羊精子体外获能后的精子活力、质膜完整性、顶体完整率、获能比例及受精和卵裂的影响,为改善山羊精子体外获能效果和研究获能机理提供了必要的数据。主要实验结果如下：1、在获能液中添加5、10、25、50和100μg/mL肝素处理45min时,添加50和100μg/mL肝素精子获能比率最高（分别为55%和56%）,但添加100μg/mL肝素处理后顶体完整率明显（P<0.05）低于对照组。说明山羊精子获能的最佳肝素浓度为50μg/mL。2、肝素作用时间（0, 10, 20, 30, 45, 60 和120 min）的延长,获能精子比例逐渐提高。其中,肝素处理45～120 min各组的获能精子比例差异不显著（P>0.05）,处理120 min组的精子活力和质膜完整率显著低于其它各组。说明50μg/mL肝素处理精子获能的最佳时间是45～60 min。3、在42℃和38.5℃下处理时,获能精子比例显著高于15℃和37℃,但42℃处理后精子活力和顶体完整率显著低于其它温度。因此,385℃为山羊精子获能的最佳温度。4、与输卵管上皮细胞共培养获能精子比例显著高于对照组和卵丘细胞组,但精子活力、质膜完整率和顶体完整率差异不显著。输卵管上皮组的受精率（91.3％）和卵裂率（72.2％）显著高于对照组（81.2％,65.0％）。说明与输卵管上皮细胞共培养能显著提高肝素处理山羊精子体外获能的效果。     

Initial Heparin Therapy in Acute Myocardial Infarction

The administration of heparin during the first 48 hours following acute myocardial infarction is widely practised. Heparin treatment is also recommended for acute coronary insufficiency on the grounds that it may prevent development of an impending myocardial infarction. These measures had been accepted without support of a controlled clinical trial. By random selection, 101 patients hospitalized with a provisional diagnosis of acute myocardial infarction received heparin (100 mg. intravenously every eight hours for 48 hours) and 105 patients were assigned to a control group. Both groups of patients received bishydroxycoumarin (Dicumarol). The mortality in the heparin series was 30% and in the control group, 28%. A significantly large number of the heparin-treated patients developed clinical and laboratory proof of recent myocardial infarction. It is concluded that early intermittent intravenous heparin treatment does not lower the mortality in patients with acute myocardial infarction nor does it prevent impending myocardial infarction in patients with acute coronary insufficiency.

Changes in gastric mucosa after vagotomy and gastrojejunostomy for duodenal ulcer.

Gastric mucosa was studied histologically in 141 patients. Eighty two had undergone vagotomy and gastrojejunostomy between 15 and 25 years previously for duodenal ulcer, and 59 control patients had a long history (minimum 15 years) of duodenal ulcer treated medically. No carcinoma was found in either group. Two patients with severe dysplasia and 13 patients with moderate dysplasia were found in the study group, compared with none in the control group (p less than 0.01). Intestinal metaplasia was seen in 44 (53%) of the study group and 16 (27%) of the control group (p less than 0.01). Atrophy and gastritis were more severe (p less than 0.01 for atrophy; p = 0.05 for gastritis) in the study group. Gastric mucosal changes were more severe after surgical treatment for duodenal ulcer than after medical treatment, and possibly a high incidence of gastric carcinoma may occur 25 years after vagotomy and gastrojejunostomy.
