Abstract

Background: This study was accomplished to evaluate the anticipated effects of glimepiride on some of the hematological parameters besides the antioxidant enzymes of the alloxan-induced diabetic and healthy rats.

Methods: In this study, thirty-two adult albino male rats were adopted. The animals were set in a random manner into four groups of eight rats each. The animals of the control group were dosed orally with 5ml distilled water. The second were injected intraperitoneally with 150 mg/kg of Alloxan one time to induce diabetes. The third group were administered a daily oral dose of 5 mg/kg of Glimepiride. The fourth group were injected with alloxan in the same manner as the second group and then dosed orally with 5mg/kg of glimepiride. The above-mentioned experimental protocol has extended for one month and thereafter the planned tests were done.

Results: The results showed that diabetes induced by alloxan led to significant decline in the packed cells volume (PCV), hemoglobin concentration (Hb), platelets (PLT), red blood cell counts (RBC), glutathione (GSH), alanine aminotransferase (ALT) and alkaline phosphatase (ALP)at (p≤0.05) with significant elevation in the total white blood cells count (WBC), malondialdehyde (MDA), erythrocytes sedimentation rate (ESR) and aspartate aminotransferase (AST) comparing with those of the control group. The use of glimepiride alone to the healthy rats led to significant decline in RBC,PLT, GSH and AST with significant elevation in ESR and WBC without an effect on the PCV, Hb, MDA, ALT and ALPat (p≤0.05) comparing with those of the control group. Treatment of alloxan-induced diabetic rats with glimepiride led to significant decline in RBC, HB and PCV with significant elevation in WBC, PLT, GSH, MDA and ALT at (p≤0.05) compared with the control group.

Conclusion: We conclude that glimepiride does affect the blood parameters and the antioxidant enzymes.

Introduction6th button-01

People who are afflicted with diabetes are of huge numbers around the globe. These people use different medications to control diabetes. One of those medications is the glimepiride. Glimepiride comes with different brand names like Amaryl, Azulix, Betaglim, Daoryl, Diaglim, Dibiglim and others. We think that glimepiride has anticipated side effects; thus we have made this study to evaluate glimepiride.

The relationship between the oxidative stress and diabetes mellitus was referred to by many studies including both two main types of DM type I and type II [1]. DM is well known to cause malfunctions in different body systems including a malfunction in the antioxidant system [2]. Glimepiride is one of the second-generation sulfonylurea a group of insulin secretagogues [3]. Glimepiride stimulates the release of insulin when it binds to specific cite of beta cells leading to closure of KATP and hence the depolarization of membrane which leads to release of insulin [4].

In this study, thirty-two adult albino male rats were adopted. They weighed 250-300 grams in range. The conditions of the experiment were typical and unified. Then, the animals were set in a random manner into four groups of eight rats each.

1- Control group (C): a dose of 5 ml distilled water was administered orally.

2- The second group (A): animals were injected intraperitoneally with 150 mg/kg of alloxan one time to induce DM.

3- The third group (GLM): animals were administered a dai­ly oral dose of 5 mg/kg of Glimepiride.

4- The fourth group (AGLM): animals were injected with Alloxan in the same manner as the second group and then treated orally with 5mg/kg of Glimepiride. The experimental protocol has extended for one month and thereafter the planned tests were performed.  

Results6th button-01

Alloxan could cause significant decline in RBC, Hb, and PCV, on the other hand significant elevation in WBC and ESR comparing with those parameters of the control group at (p≤0.05). The same occurred when Glimepiride was dosed immediately after dosing with Alloxan. When Glimepiride was offered alone, it caused significant decline in RBC with significant elevation in WBC without affecting the HB, PCV and ESR compared to with those parameters of the control group at (p≤0.05). The effects of Alloxan and Glimepiride can be seen in table 1.

Focusing on some biochemical markers, Alloxan could cause a significant elevation in MDA, significant decline in AST, ALT, ALP and GSH compared with the control group at (p≤0.05). When Glimepiride was offered after dosing with Alloxan, it caused a significant elevation in ALT with a significant declination in GSH without affecting the AST, ALP and MDA.

Glimepiride causes significant decline in AST and GSH without affecting the ALT, ALP, and MDA compared to with those parameters of the control group at (p≤0.05), a scan be seen in table 2. The effects of Alloxan can be explained by focusing on the effects of diabetes and the related sequelae. Diabetes causes an elevation in the oxidative stress status of the body and hence activates the damage to the cell membranes depletion of the antioxidant enzymes of the defense body system [5, 6]. Oxidation of sulfhydryl groups of the hemoglobin peptide chains is caused by the elevated oxidative status which leads to decline of hemoglobin [7, 8]. The oxidative stress status also could cause an elevation in the total white blood cells as a defensive body response [7- 9].
Glutathione declination might be caused as a result of a decrease in NADPH coenzyme due to oxidative stress. NADPH is a coenzyme to glutathione reductase which renders the reduced form of glutathione from the oxidized.

Glutathione declination might be caused as a result of a decrease in NADPH coenzyme due to oxidative stress. NADPH is a coenzyme to glutathione reductase which renders the reduced form of glutathione from the oxidized one. The elevated levels of MDA might be due to the effects of diabetes [10-13]. The DM causes an increase in the free radicals and hence an increase in the peroxidation of lipids of the cell membranes. It can be concluded that Glimepiride could cause malfunctions and disturbances in the hepatic enzymes, erythropoiesis, and the immune system. And the same is true for Alloxan.
