RESUMO

OBJECTIVE: To determine the aetiological factors of amenorrhea. METHODS: The pilot cross-sectional study was conducted in Government Naserullah Khan Babar Memorial Hospital, Peshawar, Pakistan, from January 2015 to December 2017, and comprised amenorrhea cases. Cases were analysed according to their clinical profile, ultrasound findings and biochemical tests. Data was analysed using SPSS 20. RESULTS: There were 100 patients with a mean age of 22.17±5.52 years (range: 14-36 years). Anatomical defects were the most common cause in 60(60%) patients. Imperforate hymen and transverse vaginal septum were found in 7(7%), 7(7%) patients each, while mullerian abnormalities were found in 46(46%) patients. Hypergonadotropic hypogonadism and polycystic ovarian syndrome were found in 17(17%) patients each. CONCLUSIONS: Anatomical defects were found to be the most common cause among amenorrhea patients.

RESUMO

Plant-derived natural products are of great interest due to their diversity in modern drug discovery. Sarcococca saligna has been used for the treatment of different diseases. The present study was aimed at isolating phytochemical constituents including Alkaloid-C (a), Dictyophlebine (b), Sarcovagine-D (c) and Saracodine (d) Holaphylline (e) from Sarcococca saligna to investigate the anticancer effect of these compounds. These compounds were evaluated for inhibition of aromatase enzyme of breast cancer in assistance by molecular docking simulations to understand molecular interaction between the enzyme and ligands. The IC50 values of compound 1 and 5 were found 138.27 ± 0.01 µl and 12.91 ± 0.01 µl, respectively, and both were found active due to their bulky structures in comparison to the active site of aromatase enzyme. The standard drug exemestane showed potent activity in comparison with the test compounds, having IC50 values of 0.052 ± 0.01 µl. Both compounds showed favorable electrostatic interactions with the active site of aromatase enzyme but the shape and steric bulk of the compounds was the limiting factor in their inhibitory effects. New lead compounds could be generated after extensive modifications guided by computational and experimental tools as a possible anticancer agents by targeting aromatase enzyme.

RESUMO

It has been reported that the major cause of mortality in diabetes is cardiovascular diseases and contribution of hypertension is significant in this context. Pioglitazone, a thiazolidinedione class of therapeutic agent is used to treat type 2 diabetes mellitus. Telmisartan, an angiotensin receptor blocker antihypertensive has been reported to have beneficial effect if co-administered with pioglitazone for the management of diabetes complications. The present research work aims to evaluate the safety/toxicity profile of this combination in rat model. The investigation was carried out after co-administering the drugs to the rats for 28 days at three dose levels of 50, 100 and 150 mg/kg covering low to high dose ranges. Various hematological and biochemical parameters were studied in addition to the histopathology of the major organs in order to evaluate the toxicity profile of the combination. Absence of mortality and histopathological changes as well as unaltered hematological and biochemical parameters was observed. This preliminary investigation concludes that the combination of pioglitazone and telmisartan can primarily be stated as safe in animals, even at the dose level which is several folds higher than the intended human dose. Thus, this combination can be explored in future to develop a rational therapy regimen to treat hypertensive diabetic patients.
