ABSTRACT
Purpose: To investigate the effect of amitriptyline (Ami) and sertraline (Sert) in diabetes neuropathy. Methods: Diabetes was induced in 3 groups of rats (n=6) with streptozotocin (STZ; 55mg/kg; i.p.). Two of the groups of diabetic rats received amitriptyline (15 mg/kg; p.o) and sertraline (30 mg/kg; p.o.) while another 2 groups (n=6) received the same drug treatment without prior administration of STZ. A normal group (n=6) of rats and STZ-induced group (n=6) of diabetic rats served as controls.The blood glucose; glycosylated hemoglobin (GHb); pain sensitivity and neuromuscular strength in all the rats were determined. Results: Ami (15mg/kg; p.o.) produced severe hyperglycemia (p 0.01) whereas Sert (30mg/kg; p.o.) produced significant hypoglycaemia in the diabetic rats. Ami significantly increased the GHblevel while Sert had no significant effect. Both Ami and Sert raised the grip strength that was significantly reduced by STZ. When administered for 3 weeks; Ami and Sert increased the STZ induced reduction of the grip strength in the diabetic rats (p 0.01). STZ (55mg/kg; i.p) increased the pain sensitivity. Pain sensitivity was significantly reduced by Ami (15 mg/kg; p.o; administered for 3 weeks) in the diabetic rats but marginally reduced in the normal group. However 3-week administration of Sert (30 mg/kg; p.o.) significantly reduced the pain sensitivity in both the diabetic and normal rats (p 0.01) when compared with STZ treated group. Conclusion: Sertraline could offer a good choice in the treatment of diabetic neuropathy particularly in patients with depression being treated with amitriptyline

The aim of this work was to investigate the effect of daily oral administration of root bark methylene chloride/methanol extract of Ceiba pentandra (Linn) in streptozotocin-induced type-2 diabetic rats; and the effect of this treatment on the physiological and metabolic parameters that are related in diabetic animals. The diabetic rats were separated into four groups and each given the following samples by gavage; daily for 28 days: vehicle (diabetic control); Ceiba pentandra extract at the dose of 40 mg/kg; Ceiba pentandra extract at the dose of 75 mg/kg and glibenclamide (5 mg/kg). All the parameters were also determined in healthy (non diabetic) rats for comparison. The methylene chloride/methanol extract of Ceiba pentandra treatment significantly reduced the intake of both food and water as well as the levels of blood glucose; serum cholesterol; triglyceride; creatinine and urea; in comparison with diabetic controls. The treatment also improves impaired glucose tolerance but no effect was observed in the level of hepatic glycogen. The effect of Ceiba pentandra (40 mg/kg) was more prominent when compared to glibenclamide in lowering blood glucose; with the added benefit of considerably reducing serum cholesterol and triglyceride concentrations. The results of this experimental animal study indicated that Ceiba pentandra possesses antidiabetic activity; and thus is capable of ameliorating hyperglycaemia in streptozotocin-induced type-2 diabetic rats and is a potential source for isolation of new orally active agent(s) for anti-diabetic therapy
