Evaluation of Antidiabetic and Antihyperlipidemic Activity of 80% Methanolic Extract of the Root of Solanum incanum Linnaeus (Solanaceae) in Mice.

Background: Conventional antidiabetic drugs are linked with a number of contraindications and untoward effects. The root decoction of Solanum incanum L. has traditionally been used to treat diabetes. However, its safety and efficacy have not been scientifically authenticated yet. Hence, the study was conducted in mice to corroborate its antidiabetic potential and safety profile. Methods: Using normoglycemic, oral glucose-loaded, and streptozotocin-induced diabetic mice models, the hypoglycemic and antihyperglycemic activities of 80% methanolic root extract were investigated. On streptozotocin-induced diabetic mice, the effect of the test extract on diabetic lipid profile and body weight was also investigated. Further, the in vitro α-amylase inhibition activity was assessed. Results: The test extract was safe at a limit test dose of 2 g/kg. Dose-dependent α-amylase inhibition activity was seen with peak percentage inhibition of 75.95% at 700 µg/mL. In normoglycemic mice, the plant extract showed statistically significant hypoglycemic activity at 200 and 400 mg/kg (P < 0.001) at 6 h and 4 and 6 h of treatment, respectively; in oral glucose-loaded mice, at both the test doses, the glucose level was also significantly dropped at 120 (P < 0.01) and 60 and 120 min (P < 0.001), respectively; whereas, in the third model, the test extract showed significant antihyperglycemic activity at 100 mg/kg (P < 0.05) on the 14th day and at 200 (P < 0.01) and 400 mg/kg (P < 0.001) on the 7th and 14th day of treatment. Similarly, following repeated administration of the test extract at 200 and 400 mg/kg, the body weight was significantly improved on the 14th day (P < 0.05) and on the 7th and 14th day (P < 0.01), respectively, while diabetic dyslipidemia after 14 days (P < 0.05). Conclusion: The study revealed that the test extract showed promising antihyperglycemic and antihyperlipidemic activity. Thus, the findings back up its use in Ethiopian remedies for diabetes.

Evaluation of In vivo antidiarrheal activity of hydro-methanolic extract of the root of Rumex nepalensis in Swiss Albino mice.

Background: Natural products have been utilized by human beings for thousands of years to relieve a variety of ailments, including diarrhea. Conventional antidiarrheal drugs are associated with multiple adverse effects and contraindications. Traditionally, Rumex nepalensis by crushing the root, mix with water and then drunk the juice is extensively used for treating diarrhea. However, no scientific research has been done yet to support its antidiarrheal efficacy and safety. Hence, the aim of the study was to evaluate the antidiarrheal activity and safety profile of the plant in mice. Methods: The hydro-methanolic extract was extracted through a cold maceration technique using 80% methanol. Castor oil-induced diarrheal, gastro-intestinal transit, and enteropooling models have been employed to assess the antidiarrheal activity of the test extract at doses of 100, 200, and 400 mg/kg. Results: The crude root extract caused no mortality at a single limit test dose of 2 g/kg throughout the first 24 h and for the rest of the 14 days. In a castor oil-induced diarrheal model, the hydro-methanolic extract markedly delayed the onset of diarrhea, reduced the weight of wet and total feces at 100 (P<.05), 200 (P<.01), and 400 mg/kg (P<.001) test doses. Meanwhile, at 200 (P<.01) and 400 mg/kg (P<.001) doses, the plant extract considerably lowered the weight and volume of intestinal contents. In the gastro-intestinal transit model, however, a dramatic inhibition in the charcoal meal travel was noticed at 100 (P<.05), 200 (P<.01), and 400 mg/kg (P<.001) test doses. The peak antidiarrheal index was exhibited at the highest dose of the test extract. Conclusion: The study speculated that Rumex nepalensis root extract possesses antidiarrheal activity, which could be owing to its inhibitory effect on both gastro-intestinal motility and fluid secretion.

Evaluation of the Antiulcer Activity of Methanolic Extract and Solvent Fractions of the Leaves of Calpurnia aurea (Ait.) Benth. (Fabaceae) in Rats.

Introduction: In Ethiopia, traditionally, the leaves of Calpurnia aurea have been utilized to treat peptic ulcer disease. Therefore, the objective of the present study was to examine the antiulcer activity of Calpurnia aurea hydromethanolic leaf extract and solvent fractions in rats. Methods: The ulcer-healing potential of the crude test extract was assessed in rats by adopting pyloric ligation-, acidified ethanol-, and acetic acid-induced ulcer methods; while, in solvent fractions, the acidified ethanol-induced ulcer model was used. In all models, three serial test doses (100, 200, and 400 mg/kg) were given and the antiulcer activity was investigated. Standard drugs like sucralfate (100 mg/kg), omeprazole (20 mg/kg), and cimetidine (100 mg/kg) have been used as a positive control; whereas distilled water (10 mL/kg) was used as the negative control. Parameters like ulcer index, total acidity, pH, gastric volume, and gastric mucin level were all measured. Results: In an acute toxicity study, the test extract at the limit test dose (2 g/kg) was safe following a single dose administration. In pyloric ligation-induced ulcers, the plant extract at 200 and 400 mg/kg significantly reduced the ulcer index, the volume of stomach secretion, and total acidity while raising gastric pH and mucus content (P < 0.05). Likewise, in the acidified ethanol- and acetic acid-induced ulcer models, the extract at both test doses (200 and 400 mg/kg) also displayed a substantial reduction (P < 0.05) in ulcer index. Among the fractions, the ethyl acetate fraction revealed remarkable cytoprotective activity at all test doses and the aqueous fraction at 400 mg/kg (P < 0.05). In contrast, the effect of chloroform fraction was found to be negligible. The peak ulcer inhibition was noted at 400 mg/kg of ethyl acetate fraction (52.4%). Conclusion: The study showed that the crude extract and solvent fractions possess remarkable antiulcer activity.

Antidiarrheal Effect of 80% Methanol Extract and Fractions of the Leaves of Ocimum lamiifolium in Swiss Albino Mice.

Introduction: Worldwide, in children of under five years of age, diarrhea is responsible for more than 760,000 annual deaths. It is treated with both modern drugs and traditional medicinal plants, including O. lamiifolium. But the use of this plant as an antidiarrheal agent is not scientifically validated. Therefore, this study was aimed to evaluate antidiarrheal efficacy of the plant. Method: The leaf powder was macerated by 80% methanol and then fractionated using n-hexane, n-butanol, and distilled water. Antidiarrheal activity was evaluated through different models (castor oil-induced diarrhea, enteropooling, and motility) using onset, number of wet feces, fluid content, weight and volume of intestinal content, and motility as test parameters by administering treatment doses to groups of mice. Group I received 10 mL/kg of the dissolving vehicle, Group II received either loperamide or atropine, and Groups III-V received extract doses of 100, 200, and 400 mg/kg, respectively. One-way ANOVA was used to analyze the data, followed by Tukey's post-hoc test. Results: The crude extract exhibited a significant effect on the fluid content of feces at all tested doses. Additionally, the n-butanol and distilled water fractions revealed significant effects on onset of diarrhea at 400 mg/kg (p < 0.05), while the n-hexane fraction showed significant effects on number of wet feces, onset, and fluid content of feces at all tried doses. The crude extract and all the fractions (at 200 and 400 mg/kg) decreased the weight and volume of intestinal content significantly. Similarly, both the crude extract and distilled water fraction at 400 mg/kg as well as n-butanol and n-hexane fractions at 200 and 400 mg/kg showed meaningful differences on peristaltic index as compared to the negative control. Conclusion: The results revealed that the leaf extract of O. lamiifolium has an antidiarrheal activity, which supports the traditional medical practice.

Glinus lotoides linn. Seed extract as antidiabetic agent: In vitro and in vivo anti-glucolipotoxicity efficacy in Type-II diabetes mellitus.

Background: Diabetes, especially type-II, prevailed despite recent medical advances. An edible G. lotoides (GL) seed is sold in Ethiopian traditional market such as 'Merkato' and used in folkloric medicine to treat diabetes. But to date not scientifically proven in this optic. As a result, this study set out to validate this claim. Methods: Following G. lotoides seed has been extracted, its antidiabetic efficacy was initially validated in vitro before in vivo investigation. The in vitro activity was probed by employing carbohydrate and lipid metabolizing enzymes inhibition assay. Based on this fact, the in vivo antidiabetic efficacy was conducted in normoglycemic, oral glucose-loaded and streptozotocin (150 mg/kg)-nicotinamide (65 mg/kg)-elicited type II diabetic rats. Results: The extract's LD50 was found to be greater than 2 g/kg. In vitro tests pill up evidence that seed extract foils carbohydrate and lipid metabolizing enzyme activities (p < 0.001). On the other hand, seed extract significantly abridged blood glucose in normoglycaemic rats markedly (p < 0.05-0.001). The highest dose exhibited the strongest glucose tolerance effect, with a maximum slaying (41.1%) in glucose-loaded rats' plasma glucose (p < 0.001). All doses of the extract ameliorate blood glucose levels significantly in diabetic rats after 4 weeks of therapy (p < 0.05-0.001). Likewise, all test doses tempered harmful lipides in diabetic rats markedly (p < 0.05-0.001). But HDL (p < 0.01-0.001) and body weight losses (p < 0.05-0.001) were rectified. Conclusion: In consequence, our data unveils the safety and glucolipotoxicity inhibition potential of G. lotoides seed extract, authenticating the traditional standpoint that it might be converted into a viable anti-diabetic lead upon subsequent investigations.

Prevalence and Associated Risk Factors of Endoparasites among Under-Five Children in Debre Tabor Comprehensive Specialized Hospital, Debre Tabor, Northwest Ethiopia: A Cross-Sectional Study.

Many endoparasites are still considered neglected tropical illnesses. The term "endoparasites" refers to infections caused by both helminths and protozoa. In many places in Ethiopia, particularly Debre Tabor, epidemiological data on the prevalence and associated variables of endoparasites among under-five children is unavailable. Thus, the aim of this study was to gather baseline data on the prevalence of endoparasites and their associated variables among under-five children who visited the Debre Tabor comprehensive specialized hospital in Northwest Ethiopia. A hospital-based quantitative cross-sectional study was used. The study was carried out from May 1 to November 30, 2021. Study participants were selected by a systematic sampling technique. The stool specimen was examined for the presence of different stages of intestinal parasites (adult, trophozoite, larvae, cysts, and ova) using direct wet mount, modified formal-ether sedimentation, and modified Ziehl-Neelsen methods. The IBM SPSS statistical package (version 23) was used to enter and analyze the collected data. The data was summarized using frequency tables and a bar chart. The adjusted odds ratio and p value <0.05 were used to declare the final association. In the present study, a total of 258 under-five children and their mothers/guardians were involved in the study, with a response rate of 100%. More than half of the respondents, 137 (53.10%), were females, and 159 (61.63%) were in the age group of 24 to 59 months. The overall prevalence of one or more endoparasites among under-five children was 45 (17.44%). Multivariate logistic regression analysis showed that health supervision, child food freshness, regular trimming of fingernails, and children's playground cleanliness were significantly associated with childhood endoparasites. The present study demonstrated a higher prevalence of endoparasites among under-five children. Health supervision, child food freshness, regular trimming of fingernails, and children's playground cleanliness were significantly associated with endoparasites. Thus, strengthening health education about food, personal, and environmental hygiene for both children and their mothers/guardians is crucial.

Antimalarial Efficacy of Hydromethanolic Root Extract and Solvent Fractions of Urtica simensis Hochst. ex. A. Rich. (Urticaceae): An Experimental Study on Plasmodium berghei-Infected Mice.

Background: Despite modern therapeutic armamentariums, malaria remains a 21st century public health menace. The issue of combating malaria is the ever-growing resistance to high-tech medications in which novel phytomedicines are highly demanding, a rapidly expanding research avenue. In Ethiopian folklore medicine, Urtica simensis has been used to treat malaria by drinking its juice after the dry roots have been mashed and combined with water. Hitherto, no in vivo study has been reported in the literature so far. To substantiate this folkloric claim, the present work herein was done. Methods: An acute oral toxicity study was conducted as per the standard protocol. To rule out, the extract's inherent potential effects on bodyweight, basal body To, and PCV changes were tracked for two weeks. A four-day suppressive model and a curative assay model were utilized to investigate the antimalarial activity of the plant. Percent parasitemia suppression, packed cell volume, mean survival date, bodyweight, and rectal body temperature were used to determine antimalarial activity. Result: An acute toxicity study reveals that Urtica simensis was atoxic at a dose of 2000 mg/kg. It also affirms that U. simensis is free from intrinsic potential effects of interfering with bodyweight, temperature, and packed cell volume evolution. Both crude extract and its solvent fractions at all test doses exerted significant (P < 0.001) inhibition of parasitemia as compared to the control group. CF400 mg/kg provided the greatest chemosuppressive effect (79.24%). In a curative experiment, crude extract and CF were able to prevent the cardinal indications of P. berghei-induced malaria, such as weight loss, hypothermia, parasitemia, and anemia. Both crude extracts and their solvent fractions prolong survival dates. Conclusion: The antimalarial activity of the crude extract and its solvent fractions was promising, confirming previous assertions. As a result, more research studies into chemical entities may be required.

Antidiabetic Activity of Hydromethanolic Extract of Crude Dorstenia barnimiana Root: Validation of In Vitro and In Vivo Antidiabetic and Antidyslipidemic Activity.

BACKGROUND: Despite modern therapeutic armamentaria, DM remains a 21st-century public health menace. Novel phytomedicines are a rapidly expanding focus of research. The juice of Dorstenia barnimiana roots has long been used for the treatment of diabetes mellitus in traditional Ethiopian medicine, but its efficacy has not been supported by in vitro or in vivo scientific study. To investigate this, the present work was performed. METHODS: In this experimental study, simple random sampling was applied. Healthy male mice were used in normoglycemic and oral glucose-tolerance test (OGTT) models. Streptozotocin (IP, 150 mg/kg)-administered diabetic male mice were utilized. Animals were randomly divided into five groups of six each. Group I received 10 mL/kg distilled water, groups II-IV received 100 (DB100), 200 (DB200), and 400 (DB400) mg/kg crude extract, respectively, and group V received glibenclamide 5 mg/kg. A sham group (group VI) was added that received 10 mL/kg distilled water. All treatments were given orally. FBG, serum-lipid profiles, and body-weight changes were then measured. In vitro α-amylase inhibitory activity was also evaluated. RESULTS: The doses were atoxic up to 2,000 mg/kg. There was α-amylase inhibition activity of 67.52% at 500 µg/mL with an IC50 of 4.595 µg/mL. The OGTT revealed an antihyperglycemic effect of the crude extract. This was not attributed to a hypoglycemic side effect. In the diabetic mouse model, it shrank FBG levels remarkably. There were also significant reductions in serum TC, TGs, VLDL-C, and LDL-C. Nevertheless, HDL-C and body-weight levels returned. CONCLUSION: The present study confirmed the safety and promising in vivo antidiabetic and antidyslipidemic activity of D. barnimiana, thus corroborating the traditional claim.

Patients' satisfaction with outpatient pharmacy services and associated factors in Debre Tabor comprehensive specialized hospital, Northwest Ethiopia: A cross-sectional study.

INTRODUCTION: By measuring patients' satisfaction, providers can gain insight into several elements of health care services, including the effectiveness of their care and the level of empathy they exhibit. The aim of this study was to assess patient satisfaction with pharmaceutical services and associated factors in public hospitals located in Northwestern Ethiopia. METHODS: An institution-based quantitative cross-sectional study was used. The study was carried out in an outpatient pharmacy from January 1-June 30, 2021. Participants were selected by a systematic sampling technique. The IBM SPSS statistical package (version 23) was used to enter and analyze the collected data. The findings were presented using descriptive statistical methods. To find factors linked to satisfaction, binary logistic regression was used. RESULTS: The final analysis included a total of 401 samples. More than half of the participants (229, or 55.1%) were female. The overall mean score of satisfaction was 30.6 out of a maximum of 100 scores. By taking this mean score as a cut-off point, 204 (50.9%) of the study participants had satisfaction with the outpatient pharmacists' service. Participants' responses scored on the uncomfortable and inconvenient waiting areas [AOR = 0.31; 95%CI, (0.13, 0.49)] were found to be negatively associated with the level of patients' satisfaction. Also, the unavailability of medications [AOR = 0.12; 95%CI, (0.02, 0.37)] was negatively associated with the respondent satisfaction. Uncomfortable and inconvenient private counseling areas [AOR = 1.37; 95%CI, (0.79, 4.42)] showed a negative association with their satisfaction. CONCLUSION: Patients' satisfaction levels with pharmacy service were found to be greater than 50%. The socio-demographic characteristics of patients have no association with their level of satisfaction, but their perception of uncomfortable private counseling areas and waiting areas was negatively associated with their satisfaction.

Hydromethanolic Crude Extract of the Leaf of Urtica simensis Hochst. ex. A. Rich. (Urticaceae) Acquires Appreciable Antiulcer Effect: Validation for In Vivo Antiulcer Activity.

BACKGROUND: Urtica simensis has been used for the treatment of peptic ulcer disease in Ethiopian folkloric medicine by drinking its juice after boiling the semicrushed leaf. To our latest understanding, no in vivo study was available regarding its antiulcer activity. The present study was done to appraise the ulcer-protective and ulcer healing activity of hydromethanolic crude extract of leaf of U. simensis in rats. METHODS: Preliminary qualitative phytochemical screening and oral acute toxicity were carried out using a standard protocol. To validate U. simensis in vivo antiulcer potential pyloric ligature, cold restraint stress and acetic acid-induced ulcer models were employed. The extracts (100, 200, and 400 mg per kg of body weight per day), standard treatment (omeprazole 20 mg/kg/day), and vehicle (distilled water 10 ml/kg/day) were given to treatment, positive, and negative controls by oral gavage, respectively. Parameters were then evaluated accordingly after the humane scarification of rats. RESULTS: Any sign of toxicity was not observed in the oral acute toxicity test. The crude extracts exerted a significant (P < 0.05) inhibition of ulcer risk compared to the negative control. In the pylorus ligation-induced ulcer model, its antisecretory activity was in a dose-dependent manner. The highest gastroprotective effect (67.68%) was exhibited by the 400 mg/kg/day dose of 80% methanolic crude extract. Regarding the chronic ulcer model, treatment at a dosage of 100, 200, and 400 mg/kg/day cures ulcers by 33.54%, 58.33%, and 67.07%, respectively, as compared to the negative control groups remarkably. CONCLUSION: The findings of the present study confirmed the safety and a promising in vivo ulcer healing and antiulcerogenic activity of U. simensis, thus supporting the traditional claim. In-depth investigations on the plant, however, are highly recommended.
