Studies reported from Ethiopia depict poor health outcomes and management of diabetes cases and low patients’ adherence to recommended regimens including medications. Among factors determining adherence to medications that are amenable to interventions are patient perceptions to their recommended medications. This study thus aimed to assess adherence to anti-diabetic medications and determinant factors including medication related beliefs among type 2 diabetic patients attending their treatment in primary healthcare centers of Addis Ababa, Ethiopia using standardized measures. Methodology: A facility-based cross-sectional study design was followed to assess study participants recruited from among type 2 diabetic patients attending their treatment in three health centers in Kirkos Sub City, Addis Ababa from April to June, 2013. For the assessment interviewer administered structured questionnaires based on standardized measures such as the 8-item Morisk’s Medication Adherence Scale (MMAS) and the specific Belief about Medications Questionnaire (BMQ) were used. Result: A total of 155 study participants, all of whom were on oral hypoglycemic agents were involved in the study among whom 53.5% were male and...

Aim: The present study evaluated the anti-diabetic, anti-hyperlipidimeic, antioxidant activities and renal protective effect of aqueous extract from Ganoderma. lucidum fruiting bodies in streptozotocin induced diabetic rats. Material and Results: Qualitative and quantitative phytochemical analysis for G. Lucidum aqueous extract showed the Presence of high concentration of tannins content. Thin layer chromatography (TLC) revealed the presence one tannin spot which high performance liquid chromatography (HPLC) analysis confirmed that the tannin compound is tannic acid. Extracted tannic acid showed highly antioxidant activity in vitro. Two doses of the extract were administered intraperitoneally. Tannic acid significantly decrease blood glucose levels and significant increase in serum insulin in addition, it improved serum lipid profile in diabetic rats compared to untreated diabetic group. Results: Showed that tannic acid also had potent antioxidant activity in vivo, as it significantly decreased MDA while GSH and GPx in erythrocytic and renal tissues were significantly increased. Histopathological examination of kidney tissue tannic acid treated rats showed mild glomerular atrophy and minimal tubular affection with noticeably dilated blood...

The preliminary phytochemical analysis of the aqueous ethanolic extract of the bark of Thespesia populnea (L.) revealed the presence of alkaloids, unsaturated sterols, triterpenes, flavonoids and the absence of anthraquinones. The froth test indicated the presence of saponins. Most importantly this study revealed the presence of proanthocyanidins which has not been reported before. In the present study, ethyl acetate and aqueous soluble proanthocyanidin fractions (EASPA and AQSPA respectively) were extracted and purified by chromatography on Sephadex LH-20. Prussian blue test and acid catalyzed cleavage test revealed that proanthocyanidins have been successfully separated from non-proanthocyanidin phenolics. The yields of purified EASPA and AQSPA fractions were 0.081% and 0.72% (by weight) of the fresh bark. Acid catalyzed cleavage followed by TLC studies of both EASPA and AQSPA fractions showed the presence of two anthocyanidins, cyanidin and delphinidin, suggesting that they are composed of (epi)catechin and (epi)gallocatechin units with (epi)catechin being more abundant compared to the other. This was further confirmed by 13C NMR spectroscopic studies. In addition, 13C NMR spectroscopic studies...

Background: Decoction of the root of Strophanthus hispidus is highly valued in Africa herbal medicine for the treatment of skin diseases, leprosy, ulcers, malaria, dysentery, gonorrhea and in the management of inflammation. Objective: The present study aimed to evaluate the anti-nociceptive effect of the aqueous root extract of Strophanthus hispidus focusing on central involvement as well as exploring the possible mechanisms of action in Swiss albino mice of both sexes. Methods: The aqueous extract was administered in doses of 50, 100, and 200 mg kg-1 via oral route to the animals used in the various models- acetic acid-induced writhing, formalin, Haffner’s tail clip, hot plate and tail immersion tests. Results: In each of the models, the aqueous root extract of Strophanthus hispidus each possesses a significant (p< 0.05, p< 0.01, p< 0.001) anti-nociceptive effect in a dose-dependent manner. The anti-nociceptive activity of the extract may be mediated through central and peripheral mechanisms. The involvement of opioid and dopamine (D2) receptors in anti-nociception were also established. The effect of the...

Simple, sensitive and selective methods are developed for the spectrophotometric determination of drugs, viz., Esmolol hydrochloride (ESM), Ramipril (RAM), Gemifloxacin (GEM), Terazosin (TRZ) and Moxifloxacin (MOX), based on their reactivity towards KMnO4. Beer’s law is obeyed in the concentration of 4-28, 4-28, 2.6-18.2, 1.5-10.5 and 1-7 μg ml-1 for Esmolol hydrochloride, Ramipril, Gemifloxacin, Terazosin and Moxifloxacin. The methods involve the addition of excess KMnO4 of known concentration in the presence of 2M H2SO4, reactants are allowed to react and the unreacted KMnO4 is estimated with a fixed amount of Methyl Orange by measuring the absorbance at 507nm. Results of analyses were validated statistically. Statistical comparison of the results with the reference method shows excellent agreement and indicates no significant difference in accuracy and precision. These methods have been applied for the determination of drugs in their pure form as well as in tablet formulations. These methods have been validated in terms of guidelines of...
