  Background and Aim: Diuretics used as a first line therapy in the management of hypertension. Spironolactone is the fourth drug that indicated in the management of resistant hypertension. This study aimed to clarify the importance of using short term therapy for 2 weeks as add on therapy in the management of uncontrolled-resistant hypertension. Materials and Methods: A total number of 120 patients were enrolled in open label clinical study. The patients are assigned to receive 2 week therapy of a single daily dose of amiloride (5 mg) plus hydrochlorothiazide (50 mg) (Group I), or 50 mg spironolactone (Group II) or 50 mg hydrochlorothiazide (Group III). The following measurements, including the anthropometric measurement, blood pressure, lipid profile and serum electrolytes were considered. Results: Diuretics produced significant reduction of the blood pressure of systolic and diastolic that amounted 23 and 14.2% (Group I), 24.3 and 14.4% (Group II) and 25.4 and 13.0% (Group III) of the baseline value. They induced alterations in serum electrolytes in Group II and III. Conclusion: Two- week therapeutic regimens of diuretics are enough to achieve the control of blood pressure and the logic drug for resistant hypertension is spironolactone.

  Background: Proanthocyanidins are bioactive compounds, found in herbal medicines including, the Camellia sinensis plant that exhibited an antioxidant and anticancer activities in both in vitro and in vivo models. Objective: This study aimed to investigate the cytotoxic effect of white and oolong tea against cancer cells and fibroblasts and to link these effects to their content of the proanthocyanidins level. Materials and Methods: An aqueous white and oolong tea extracts (10% w/v) prepared by a microwave assisted method. Proanthocyanidins content in each extract is determined and its levels expressed as catechins. The cell lines belonged to HeLa, human rhabdomyosarcoma, mammary (AMN3) adenocarcinoma and primary rat embryo fibroblast cell lines were incubated with each tea extract (equivalent to 2.5 mg of dry weight tea) in RPMI-1640 culture media supplemented with 5% fetal calf serum. Statistical analysis achieved by using Student's t test and difference between percentages test. Results: The mean levels of proanthocyanidins in oolong tea found to be four times of that in white tea extract. The extracts of white and oolong tea significantly inhibit the growth of fibroblasts (30.6 and 24%), HeLa (32.7 and 35.3%) and rhabdomyosarcoma cells (66.3 and 59%) of the initial percentage of the cells that did not treat with tea extracts. White and oolong tea extracts did not significantly inhibit the growth of mammary-AMN3 adenocarcinoma cell line (91.7 and 77.8% versus 100%). Conclusion: White and oolong tea extracts inhibit the growth of cancer cells and fibroblasts by a mechanism that does not relate to the antioxidant-bioactive substance the proanthocyanidins.
