Antiinflammatory flavonoids from Opuntia dillenii (Ker-Gawl) Haw. flowers growing in Egypt.

Opuntia dillenii (Ker-Gawl) Haw. (Family Cactaceae), is used in folk medicine as an antidiabetic and antiinflammatory. The antiinflammatory activity of the alcohol extracts of the flowers, fruits and stems was carried out using the carrageenan-induced rat paw oedema model. The analgesic effect of the same extracts was evaluated using electric current as a noxious stimulus. The alcohol extract of the flowers revealed the most potent antiinflammatory effect and a pronounced analgesic action at a dose of 200 mg/kg. Bioassay-guided fractionation of this extract using VLC followed by Sephadex and paper chromatography, afforded three flavonoid glycosides, namely, kaempferol 3-O-alpha-arabinoside, isorhamnetin-3-O-glucoside and isorhamnetin-3-O-rutinoside. Their identification was based on physical, chemical and spectroscopic data.

Evaluation of extracorporeal shock wave therapy in Peyronie's disease.

OBJECTIVES: To evaluate the results of extracorporeal shock wave therapy (ESWT) in patients with Peyronie's disease. METHODS: This study included 42 patients (mean age 55.4 years, range 32 to 72, SD 9.92) with Peyronie's disease. The mean duration of disease was 16.5 months (range 3 to 60, SD 13.31). Before treatment, the degree of angulation was assessed artificially by injection of 10 to 20 microg alprostadil, and Polaroid photographs were taken. Patients were also questioned about pain on erection, whether sexual intercourse was possible, and the quality of erections. All were initially treated with three sessions of ESWT (3000 shock waves). After three sessions, patients who believed that improvement had resulted or who wanted to undergo additional treatment went on to have further sessions. The mean duration of follow-up was 5.9 months (range 2 to 18, SD 4.4), after which the results were analyzed. RESULTS: Those who believed that improvement in angulation had resulted were asked to provide Polaroid photographs to assess the improvement objectively. Six (14%) said that they had excellent results, 21 (50%) had significant improvement, 7 (17%) had slight improvement, and 8 (19%) had no change. Of the 25 who had pain on erection before treatment, 21 (84%) reported complete or near complete relief after treatment. Five patients said that the quality of the erections had improved after treatment. Eight patients complained of mild and one of severe pain during or immediately after treatment; 2 of these 9 patients had both pain and bruising. CONCLUSIONS: The initial results with ESWT are promising, with minimal complications. The long-term results need to be evaluated.

Prevalence and severity of viral hepatitis in Pakistani pregnant women: a five year hospital based study.

A hospital based observational study was carried out on pregnant women presenting with either acute hepatitis or fulminant hepatic failure (FHF), during the past years. Of 53 patients, 20 (38%) developed FHF.Non-A, Non-B was the commonest cause (62%) followed by hepatitis B in 17% and hepatitis A in 4% cases. Eight women expired (case fatality rate 15%) with a high maternal mortality (62%) caused by NANB hepatitis. Perinatal mortality was 30%. Poor prognostic factors identified were lack of antenatal care, severity of jaundice, history of somnolence, gastrointestinal bleeding and a high grade of encephalopathy.
