Diabetes mellitus (DM) and hypertension usually co-exist, and when this happens, the prognosis would be worse than each disease alone. Given this, we evaluated the possible effects of valsartan and amlodipine administration on metformin-treated diabetic rats models induced by streptozotocin. Male Wistar rats (200–350 g) were fasted overnight. Then, we induced DM by administrating a single dose of 40 mg/kg streptozotocin (IP), which was confirmed after 48 h. Animals with blood sugar ≥ 200 mg/dl were considered diabetic and divided into four diabetic groups of untreated diabetic animals (Group B), diabetic animals treated with metformin (Group C), diabetic animals treated with metformin plus amlodipine (Group D), and diabetic rats treated with metformin plus valsartan (Group E). There was also a group A, consisting of normal rats with no drug treatment. After six weeks of treatment, we sacrificed the animals under chloroform anesthesia, and their blood samples were collected for hematological and biochemical analyses. The mortality rate in untreated diabetic rats was 100% before 6 weeks, but anti-diabetic treatment (metformin) significantly (P < 0.05) improved the survival rate and controlled their blood glucose level. The addition of antihypertensive drugs (amlodipine and valsartan) enhanced this curative effect. The various treated groups showed ameliorations in pathologic changes and biochemical indices, as well as, evidence of organ protection, compared with the untreated diabetic group. The study showed that adding an antihypertensive drug (amlodipine or valsartan) to metformin regimen improved outcomes in diabetic rats compared to using metformin alone.

The methanolic leaf extract of Vernonia amygdalina (MLVA) was assessed to evaluate its antidiabetic potential in rats. Diabetes was induced in male Wistar rats by the administration of alloxan monohydrate at 100 mg/kg of body weight. After 48 h, rats with fasting blood glucose levels of 200 mg/dL and above were considered diabetic and used for the study. The experimental animals were grouped into five groups (A–E) of 10 animals each. Group A rats were non-diabetic normal control, Group B consisted of diabetic control rats that received no treatment, groups C, D and E rats were diabetic rats but treated with glibenclamide, 200 and 400 mg/kg doses of MLVA respectively. Blood samples were collected at days 14 and 28 after induction for haematological and serum biochemical indices such as triglycerides, LDL, cholesterols etc. The intestine was collected and intestinal homogenate was prepared for the antioxidant studies. The extract at 200 mg/kg and 400 mg/kg doses significantly (p < 0.05) reduced blood glucose levels in extract-treated diabetic rats and also significantly increased weight gain in these rats. Most haematological parameters in treated rats experienced, while platelets and neutrophils were decreased. Biochemical indices measured were reduced in MLVA-treated groups compared with diabetic control. Treatment with MLVA also produced significant (p < 0.05) decrease in markers of oxidative stress but increased levels of enzymic and non-enzymic antioxidant markers in intestinal homogenates of treated groups compared with diabetic control. This study showed that V. amygdalina has antihyperglycaemic and in vivo antioxidant effects.

In traditional Yemeni medicine, various preparations of Loranthus regularis (L. regularis), such as powder, decoctions and infusions are commonly used to treat diabetes, kidney stone formations and inflammation. In the present study, we evaluated the antinephrotoxic effects of L. regularis extract in experimentally-induced diabetes in male Wistar rats. A single dose (60 mg/kg/day) of Streptozotocin (STZ) was used to induce type 1 diabetes. Animals were then treated for four weeks with L. regularis extract (150 or 300 mg/kg/day) by oral gavage. Renal and blood samples were subsequently harvested. Several biochemical indices, oxidative stress and inflammatory markers were assessed. Additionally, histological alterations in the renal tissue were examined. Serum glucose levels were significantly (p < 0.01) lowered while insulin levels were enhanced in L. regularis-treated diabetic animals. The increased renal markers in diabetic rats were decreased by L. regularis treatment. Serum elevated lipid profiles were markedly decreased by the plant extract. The serum and renal cytokines that were significantly increased (p < 0.001) by STZ were diminished by L. regularis treatment. Finally, renal tissue antioxidant enzymatic activity was enhanced with L. regularis treatment. Taken together, the data here indicate that L. regularis possesses therapeutic ability to reduce the development of diabetic nephropathy (DN) by minimizing oxidative injury and inflammation.

Background. The application of nanomedicine to antiretroviral drug delivery holds promise in reducing the comorbidities related to long-term systemic exposure to highly active antiretroviral therapy (HAART). However, the safety of drugs loaded with silver nanoparticles has been debatable. This study is aimed at evaluating the effects of HAART-loaded silver nanoparticles (HAART-AgNPs) on the behavioural assessment, biochemical indices, morphological, and morphometric of the hippocampus in diabetic Sprague-Dawley rats. Methods. Conjugated HAART-AgNPs were characterized using FTIR spectroscopy, UV spectrophotometer, HR-TEM, SEM, and EDX for absorbance peaks, size and morphology, and elemental components. Forty-eight male SD rats ( 250 ± 13  g) were divided into nondiabetic and diabetic groups. Each group was subdivided into ( n = 8 ) A (nondiabetic+vehicle), B (nondiabetic+HAART), C (nondiabetic+HAART-AgNPs), D (diabetic+vehicle), E (diabetic+HAART), and F (diabetic+HAART-AgNPs). Morris water maze, Y-maze test, and weekly blood glucose levels were carried out. Following the last dose of 8-week treatment, the rats were anaesthetized and euthanized. Brain tissues were carefully removed and postfixed for Nissl staining histology. Results. 1.5 M concentration of HAART-AgNPs showed nanoparticle size 20.3 nm with spherical shape. HAART-AgNPs revealed 16.89% of silver and other elemental components of HAART. The diabetic control rats showed a significant increase in blood glucose, reduced spatial learning, positive hippocampal Nissl-stained cells, and a significant decrease in GSH and SOD levels. However, administration of HAART-AgNPs to diabetic rats significantly reduced blood glucose level, improved spatial learning, biochemical indices, and enhanced memory compared to diabetic control. Interestingly, diabetic HAART-AgNP-treated rats showed a significantly improved memory, increased GSH, SOD, and number of positive Nissl-stained neurons compared to diabetic-treated HAART only. Conclusion. Administration of HAART to diabetic rats aggravates the complications of diabetes and promotes neurotoxic effects on the experimental rats, while HAART-loaded silver nanoparticle (HAART-AgNP) alleviates diabetes-induced neurotoxicity.
