Abstract
This study was conducted to determine the effect of some herbs such as 5 % marshmallow (Althaea officinalis, psyllium (Plantago ovata) and mulberry (Morus alba) leaves and mixture of them as powder on diabetic rats for 28 days. Diabetic rats were induced by injection with alloxan (150 mg / kg of rat’s body weight). The results for biological, biochemical and histopathological changes in rats were analyzed. The obtained results could be summarized in the following: 5.1. Body weight gain, food intake and food efficiency ratio: 1. The body weight gain for control positive was lower than control negative. The values were 8.4 ± 0.20 and 28 ± 0.40 g, respectively. 2. BWG % for group fed on 5% herbal mixtures showed highest value with significant differences as compared with control positive being (36.4 ±0.50, and 8.4 ± 0.20 g, respectively). While the lowest value recorded with group fed on 5% psyllium. The value was 16.8 ± 0.90 g. 3. Food intake for control positive was lower than control negative. Group fed on 5% herbal mixtures showed highest value with significant differences as compared with other groups (5% mulberry, 5% marshmallow and 5% psyllium). The values were 509.6 ±0.70, 498.4 ±1.00, 495.6 ±0.20 and 492 ± 0.50 g/day, respectively). 4. Food efficiency ratio of control positive recorded the lowest value being, 0.019 ± 0.002 %. While the highest value of food efficiency ratio with significant difference recorded with group fed on 5% herbal mixtures. The value was 0.071 ±0.008 %. 5. Group fed on 5% herbal mixtures showed the highest values of body weight gain, food intake and food efficiency ratio compared with other groups. 5. 2. Effect of mulberry, marshmallow, psyllium and Herbal mixtures on glucose of hyperglycemic rats: 1. A markedly reduction in glucose levels by different rates in diabetic rats fed on different herbs and its mixtures was observed. 2. The highest reduction with significant difference in glucose levels recorded with group fed on 5% herbal mixtures. The value was 109.1 ± 0.40 mg/dl. 3. While other groups fed on 5% mulberry, 5% marshmallow and 5% psyllium recorded a moderate reduction with significant difference in glucose levels. The values were 111.7 ± 0.50, 115.2 ± 0.80 and 124.5 ± 0.90 mg/dl, respectively. 4. Group fed on 5% herbal mixtures showed the highest reduction with significant difference in glucose levels compared with other tested groups.
