The use of traditional medicine in maternity care among African women in Africa and the diaspora: a systematic review.

There is a paucity of literature describing traditional health practices and beliefs of African women. The purpose of this study was to undertake a systematic review of the use of traditional medicine (TM) to address maternal and reproductive health complaints and wellbeing by African women in Africa and the diaspora.

Pattern and predictors of medicine use among households in Gondar Town, northwestern Ethiopia: a community-based medicine utilization study.

Medicine use can be influenced by several factors. Health managers need specific information about irrational use of medicines, in order to identify opportunities to enhance rational use of medicines in their communities. This study aimed to assess the pattern and factors associated with household medicine use in Gondar town, northwestern Ethiopia.

Methanol leaves extract Hibiscus micranthus Linn exhibited antibacterial and wound healing activities.

Infectious diseases are the most common causes of morbidity and mortality in developing countries. Wound and wound infections are also major health problem. Nowadays, medicinal plants play a major role in treatment of infectious diseases and wound healing and they are easily available and more affordable as compared to synthetic compounds. The aim of this study is therefore, to investigate the antibacterial and wound healing activities of 80% methanol extract of Hibiscus micranthus leaves using disc diffusion methods and rat excision model respectively.

A household survey of medicine storage practices in Gondar town, northwestern Ethiopia.

Household surveys are crucial to get accurate information on how medicines are acquired, and used by consumers, as they provide the best evidence in the area. The objective of this study was to document household medicine storage practices in Gondar town, northwestern Ethiopia.

Antidiarrheal activity of methanolic extract of the root bark of Cordia africana.

An ethnobotanical study in Agew-Awi and Amhara peoples in northwest Ethiopia reported that Cordia africana is used traditionally in the treatment of liver disease, amebiasis, stomachache, and diarrhea. The root and root bark are reported to be used in the treatment of diarrhea. Therefore, this study was intended to evaluate the antidiarrheal effect of C. africana against castor oil-induced diarrhea in mice. The antidiarrheal effect of the plant was tested on castor oil-induced diarrhea in mice (23-25 g) of either sex. Number of diarrheic defecations, intestinal length traveled by the charcoal meal, and weight of intestinal fluid were taken as important parameters to evaluate the antidiarrheal activity of the plant extract. In preliminary phytochemical screening tests, the methanolic extract of C. africana was found to contain phenols, flavonoids, terpenoids, and saponins. Reduction in the number of diarrheic drops was observed in groups of mice that received 200 mg/kg (P<0.05) and 400 mg/kg (P<0.01) of the extract compared to the negative controls. The percent inhibition of intestinal fluid accumulation was 26.83%, 46.34%, and 53.66% at the doses of 100, 200, and 400 mg/kg of the extract, respectively. Relative to the negative control group, the mean percent of intestinal length moved by the charcoal meal was decreased by 24.41%, 39.89%, and 51.66% in groups of mice given 100, 200, and 400 mg/kg of the plant extract, respectively. To iterate the finding, the root bark extract of C. africana was found to be effective in preventing castor oil-induced diarrhea and intestinal motility in a dose-dependent manner. This reveals that the plant material has promising antidiarrheal activity as it is claimed in traditional medical practice.

Effect of hydroalcoholic leaves extract of Indigofera spicata Forssk. on blood glucose level of normal, glucose loaded and diabetic rodents.

Diabetes mellitus is found in all parts of the world and is rapidly increasing in its coverage with alarming rate especially in Asia and Africa. Research is increasingly done with the aim of developing a relatively safe and efficacious anti-diabetic plant based products. Parallelly, this investigation was carried out to evaluate the effect of the hydro alcoholic leaves crude extract of Indigofera spicata (ISP) on the blood glucose level(BGL) of normoglycemic, oral glucose loaded and alloxan induced diabetic rodents.

Impact of clerkship attachments on students' attitude toward pharmaceutical care in Ethiopia.

The study objective is to investigate the impact of mandatory clinical clerkship courses on 5th-year pharmacy students' attitudes and perceived barriers toward providing pharmaceutical care (PC).

Consistent condom use in HIV/AIDS patients receiving antiretroviral therapy in northwestern Ethiopia: implication to reduce transmission and multiple infections.

Human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) is one of the greatest public health problems of sub-Saharan African countries. Consistent condom use, among others, remains the most effective barrier method against HIV transmission. However, existing reports on frequency of consistent condom use have targeted the general public, rather than HIV/AIDS patients due, to the assumption that condom use is not important in HIV-infected persons. Since consistent condom use among HIV/AIDS patients is vital, to prevent the virus transmission from the infected to noninfected as well as to prevent multiple infections among already infected persons, its frequency and determining factors need to be investigated.

Methanolic leaf exctract of Otostegia integrifolia Benth reduces blood glucose levels in diabetic, glucose loaded and normal rodents.

Although the leaves of Otostegia integrifolia traditionally claimed in Ethiopian folklore medicine for management of diabetes mellitus, it has not been validated. The aim of this study was therefore to investigate the antidiabetic activity of Otostegia integrifolia in rodents.

Determinants of non-adherence to antiretroviral therapy in adult hospitalized patients, Northwest Ethiopia.

The aim of this study was to assess the rate of antiretroviral therapy (ART) adherence and to identify any determinants among adult patients.

Medication adherence and its determinants among psychiatric patients in an Ethiopian referral hospital.

The degree to which an individual follows medical advice is a major concern in every medical specialty. Non-adherence to psychiatric treatment regimens has a profound impact on the disease course, relapse, future recovery, cost of health care, and the outcome for the patient. The aim of this study was to assess medication adherence and its correlates among psychiatric patients at Ayder Referral Hospital, Northern Ethiopia.

Subacute administration of crude khat (Catha edulis F.) extract induces mild to moderate nephrotoxicity in rats.

Although various studies have been conducted to shed light on the pharmacological actions of khat, little or no data are available regarding khat's effect on the renal redox system. The aim of this study was therefore to investigate the potential of nephrotoxicity associated with khat exposure in rats.
