Studies on the effects of Pluchea indica less root extract on gastroduodenal ulcer models in rats and guineapigs

The methanolic fraction of P. indica root extract was found to possess significant antiulcer activity in different experimental animal models. In preventive antiulcer tests, significant protective actions in acetylsalicylic acid, serotonin and indomethacin-induced gastric lesions were observed in experimental rats. The extract also afforded significant protection to chemically-induced duodenal lesion in guineapigs. Significant enhancement of healing process in acetic acid-induced chronic gastric lesions were also observed in the extract-treated animals.

A CASE OF EARLY GASTRIC CANCER ACCOMPANIED BY DIEULAFOY ULCER IN A YOUNG WOMAN

A case of early gastric carcinoma accompanied by Dieulafoy ulcer is presented. The patient, a 26‐year‐old female, visited our emergency room with chief complaints of massive hematemesis and tarry stool. The initial endoscopic examination revealed a superficial depressed lesion with a faded color accompanied by a tiny ulcer with converging folds at the anterior wall of the middle gastric body. Although no active bleeding vessel was found at that time, the patient was admitted to our hospital for further check‐ups and treatment. On the 6th hospital day, she developed massive hematemesis resulting in shock. Urgent endoscopy, this time, disclosed an exposed bleeding vessel at the small ulcer floor previously mentioned, and endoscopic hemostasis was achieved. Since, however, a biopsy at initial examination from the surrounding depressed area proved carcinoma, a partial distal gastrectomy was subsequently carried out. Histological examination of the resected specimen confirmed the diagnosis of carcinoma limited to the mucosa and submucosa along with findings consistent with Dieulafoy ulcer. This is a rare case of combination of early cancer and Dieulafoy ulcer particularly in such a young patient. A review of the literature is also presented.     

Randomized clinical trial of ascorbic acid in the treatment of pressure ulcers

The objective of this study was to assess the effects of ascorbic acid supplementation, 500 mg twice daily in the treatment of pressure ulcers as an adjunct to standardized treatment.

The design consisted of a multicenter blinded randomized trial. The control group received 10 mg of ascorbic acid twice daily.

Patients from 11 nursing homes and 1 hospital participated.

Main outcome measures included wound survival, healing rates of wound surfaces, and clinimetric changes over 12 weeks.

Eighty-eight patients were randomized. Intention-to-treat analysis showed that the wound closure probability per unit time (i.e., the closure rate) was not higher in the intervention group than in the control group (Cox hazard ratio of 0.78 [90% precision interval, 0.44–1.39]). Mean absolute healing rates were 0.21 and 0.27 cm²/week in the intervention and control group, respectively (PI of the adjusted difference: −0.17 to 0.13). Relative healing rates and healing velocities did not show favorable results of ascorbic acid supplementation, either. A panel scored slides of the ulcers with a report mark between 1 (bad) and 10 (excellent). The improvement was 0.45 and 0.72 points per week in the intervention and control group, respectively (PI of the adjusted difference: −0.50 to 0.20). With another clinimetric index we could not show any differences, either.

These data do not support the idea that ascorbic acid supplementation (500 vs. 10 mg twice daily) speeds up the healing of pressure ulcers.     

高压氧在治疗脊髓损伤伴截瘫及肢体慢性溃疡中的应用

本文报告了用高压氧治疗脊髓损伤伴截瘫患者１２例，肢体慢性溃疡８例。将患者置于２个大气压的单人氧舱内，每次９０ｍｉｎ。前者疗程为１周，每日２次。后者疗程为２周，每日１次。治疗结果：脊髓损伤伴截瘫患者中８例有明显而有意义的功能恢复，占６６．６％。慢性溃疡患者中有３例愈合，４例好转，有效率为８５％。作者认为：早期使用高压氧是治疗急性截瘫，尤其是不完全性截瘫的一种安全有效的方法。高压氧治疗可加速慢性溃疡创面的愈合，但不能取代溃疡面的局部处理。     

PERFORATED PEPTIC ULCER IN THE HUNTER REGION: A REVIEW OF 174 CASES

A review of 174 consecutive patients admitted with a diagnosis of perforated peptic ulcer to eight Hunter Region hospitals during 1979–86 is presented. Among the female admissions, the proportion of patients > 70 years of age was twice that in males. One-third of all perforations were in females who accounted for two-thirds of all perforated gastric ulcers. Multivariate analysis revealed that perforations located in the stomach and older age were both significant independent variables adversely affecting outcome following surgery. In contrast, shock at presentation and delay in operating were not statistically significant independent risk factors.     

溃疡病男性患者血浆睾丸酮和雌二醇浓度的变化

本文对20例溃疡病男性患者和20名男性健康者进行了血浆睾丸酮和雌二醇则定。两者相比,溃疡病男性患者血浆睾丸酮水平虽较健康者为高,但经统计学处理,无显著差异(t:1.616 P>0.05);而血浆雌二醇水平,溃疡病男性患者低于健康者,经统计学处理,有显著差异(t:2.53 P<0.05)。     

急性应激性溃疡模型的实验研究

本实验观察不同时间与方法所造成的应激性溃疡的模型。结果:禁食48小时,捆绑加浸水5小时,松绑后19小时,实验鼠胃粘膜出现多数病灶深、范围大、分布广的病灶,表现为出血、糜烂和溃疡,可谓最佳模型。     

角膜溃疡穿孔的修复与修复材料的选择

总结２１例用不同材料修复角膜穿孔的病例，修复材料分别为结膜瓣、硅胶板、断层自体皮片和同种异体角膜。结膜瓣遮盖仅２／３保存眼球，愈合后视力差，并发症多；硅胶板可在穿孔大、情况紧急时作暂时封孔保存眼球之用；自体断层皮片术后不久即溶解，角膜移植者７眼中６眼保存了眼球，且有５例植片透明，视力０．１以上。     

A Case of a Patient with a Rectal Ulcer Who Had an Unusual Defecation Habit

Abstract: This case report describes a patient with a rectal ulcer who had an unusual defecation habit. Complete healing was recognized colonoscopically after the patient was instructed to break this habit. A polyp of the ascending colon was detected by a barium enema in a 37-year-old man complaining of anal bleeding. He was admitted to our division to undergo a polypectomy. At the time of the polypectomy, a round ulcer, measuring 1 cm in diameter, was detected on the right wall of the rectum 3 cm from the anal verge. A diagnosis of mucosal prolapse syndrome of the rectum could not be made because the patient did not exhibit the characteristic habit of excessive “straining” mentioned by patients with this syndrome, and no characteristic finding of fibromuscular obliteration was found on histological examination of biopsied specimens taken endoscopically from the lesion. Repeated history taking, however, revealed that the patient had the unusual habit of inserting his finger into his rectum after defecation. He broke this habit following instruction to do so. As a result, on colonoscopic examination 15 month later, the ulcer was found to have become a scar:
