BackgroundChewing fresh leaves of the khat plant (Catha edulis forsk) is a deep rooted and widespread habit in East Africa and the Middle East. Although a body of knowledge exists about the adverse effects of khat on health, data are sparse with regard to the consequences of long-term khat chewing in resulting schizophrenic like symptoms.MethodsA crude extract of khat at different doses (100 mg/kg (K (khat)100), 200 mg/kg (K200) and 400 mg/kg (K400)) were administered for experimental group of mice whereas standard (ketamine (KT) 10 mg/kg- positive controls (KT10)) and vehicle (2 % v/v Tween-80 in distilled water – negative control groups (CON)) were administered for control groups of mice daily for two months to evaluate subchronic oral administration of crude khat extract to induce schizophrenic-like symptoms in mice. Mice were subjected to a battery of behavioural tests and parameters like locomotor activity, total time spent in social interaction and level of cognition among different groups of mice were measured and analyzed.ResultsKhat at all doses significantly increased (p < 0.001) the mean locomotor activity score of mice compared to CON. However, the mean locomotor activity score of mice treated with khat was significantly lower (p < 0.001) compared to the mean locomotor activity score of KT10 mice (p < 0.001).The mean total time score (in seconds) spent in social interaction, mean total time score (in seconds) spent in sniffing and following the partner was significantly higher (p < 0.001) in CON groups of mice compared to khat and ketamine treated groups. Moreover, in spatial memory task, the mean latency score (in seconds) to find the platform of khat and ketamine treated mice was significantly higher (p < 0.05) when compared to CON.ConclusionsSubchronic oral administration of khat showed an enhanced locomotor activity, reduced social interaction and impaired cognitive function, which demonstrated that long-term use of khat is associated with schizophernic-like symptoms.

Introduction In Ethiopia the pharmacy service has had several gaps among these were low patient satisfaction, and poor availability of essential pharmaceuticals. In addition, previous studies showed variation in magnitude of client satisfaction, and there is no previous study in the study area. Therefore, the aim of the study was to determine client satisfaction with outpatient pharmacy service and associated factors among adult clients at Dubti General Hospital in Afar, Ethiopia. Methods A hospital based cross sectional study design was employed from February 1 to March 30, 2020 at Dubti General Hospital. Participants were selected by systematic random sampling method. Bivariate and multivariate binary logistic regression was computed to assess statistical association between the outcome variable, and independent variables. AOR with 95% CI were used to show statistical Significance at P <0.05. Results The overall satisfaction towards outpatient pharmacy service was 165(40.5%). Regarding associated factors, service payment insured through their workplace was positively associated with satisfaction (AOR = 3.178, 95% CI: 1.294–7.80) where as availability of some medications (AOR = 0.393, 95% CI: 0.208–0.741), unfair medication cost (AOR = 0.613, 95% CI: 0.607–0.910), and lack of organized pharmacy work flow (AOR = 0.105, 95% CI: 0.049–0.221) were negatively associated with clients’ satisfaction. Conclusion The clients’ satisfaction in this study is low that warrants immediate corrective measures. Corrective measures should be taken based on identified gaps such as improving drug availability, pharmacy work flow, and cost of medications.
