Simultaneous determination of anthraquinones, their 8-beta-D-glucosides, and sennosides of Rhei Rhizoma by capillary electrophoresis.

The simultaneous separation and determination of major anthraquinones (emodin, chrysophanol, rhein and their glucosides, aloe-emodin, sennoside A, and sennoside B) of Rhei Rhizoma were achieved by cyclodextrin modified capillary zone electrophoresis. The running electrolyte used in this method was 0.005 M alpha-cyclodextrin in 0.03 M borate buffer (pH 10.0) containing 20% acetonitrile, with an applied voltage of 20 kV.

Bolus obstruction of pouch outlet by a granular bulk laxative after gastric banding.

BACKGROUND: Constipation is an occasional problem after gastric banding and is often caused by insufficient liquid intake. As a result, the use of laxatives is widespread in such patients. Depending on the laxative, improper use can lead to bolus obstruction above the band, as occurred in this case. CASE REPORT: A 59-year-old female with uncomplicated laparoscopic adjustable gastric banding presented 2 months after surgery with food and liquid intolerance and dysphagia after ingestion of a granular bulking laxative. Despite deflating the band, the bolus could not be washed out. Endoscopic extraction was required, revealing a 4x2 cm bolus of the laxative and a small compression ulcer. DISCUSSION: Patients not complying with nutritional recommendations after gastric banding may have insufficient liquid intake and, consequently, constipation. Under these conditions, the use of a granular bulking laxative entails the risk of esophageal obstruction above the band. CONCLUSION: Nutritional counseling after gastric banding should include the recommendation of liquid intake of at least 1.5 l/day. If constipation occurs, osmotic or paraffin oil laxatives should be used instead of bulking laxatives.

Antimicrobial activity, toxicity and the isolation of a bioactive compound from plants used to treat sexually transmitted diseases.

Extracts of six ethnobotanically selected medicinal plants (Anredera cordifolia, Elaeodendron transvaalense, Elephantorrhiza burkei, Senna petersiana, Terminalia sericea and Rauvolfia caffra) used traditionally to treat sexually transmitted diseases (STD's) were investigated for antibacterial activity using the agar dilution method. Of the six collected, Terminalia sericea, Senna petersiana and Anredera cordifolia were also investigated for cytotoxicity. The phytochemical studies on Senna petersiana resulted in the isolation of luteolin, which also showed antimicrobial activity. Only the Senna petersiana extract and luteolin isolated from it were tested for antiviral activity and showed some activity at the highest non-toxic concentration of 24 and 500 microg/ml, respectively. The results of the antimicrobial screening support the ethnomedicinal uses of these plants to some extent.

Pseudohyperaldosteronism from liquorice-containing laxatives.

Four cases of pseudohyperaldosteronism due to chronic ingestion of liquorice-containing laxatives are described. All patients had hypertension and hypokalemia with suppression of plasma renin activity and aldosterone; the diagnosis was based only on retrospective grounds. In patients with hypokalemia and hypertension a possibility of such a cause must be excluded to avoid unnecessary diagnostic procedures.

Study of various rhubarbs regarding the cathartic effect and endotoxin-induced disseminated intravascular coagulation.

Sennoside A content in hot-water extracts from 17 varieties of rhubarb obtained from the market was measured, and their respective cathartic effects were also examined in mice. A positive correlation was confirmed between the sennoside A content and cathartic effects in our experiments. Furthermore, the effects of Shisendaio [symbol: see text], with a higher sennoside A content, and Kinmondaio [symbol: see text], with a lower sennoside A content, exhibited endotoxin-induced disseminated intravascular coagulation (DIC) which related closely to Oketsu symptoms, and these effects were examined in rats. Kinmondaio exhibited weak inhibition on both reducing erythrocyte deformability and prolonging euglobulin lysis time (ELT) in DIC rats. From our results, it is possible to evaluate rhubarb's cathartic effect, one of its main drug effects, by examining the rhubarb's sennoside A content. However, it is difficult to estimate the cathartic effect according to the general market name of Rhubarb. No dramatic effect was found on the experimental models used for Oketsu symptoms such as endotoxin-induced DIC.
