Aim and objective: Clerodendrum thomsoniae leaves are used in Cameroon to manage diabetes and its related disorders. The study aimed at investigating the antidiabetic effect of the aqueous extract on diet and dexamethasone induced diabetic rats. Methods: Young mature leaves of C thomsoniae were dried, finely powdered and submitted to aqueous extraction. The dehydrated extract was tested in rats at 3 doses 312.5, 625 and 1250 mg/kg based on the local use of the plant. The effect of the extract on the fasting blood glucose in normoglycemic rats and MACAPOS 1 type diet induced diabetic rats, using respectively glibenclamide and metformin as positive control groups, were investigated. Results: AECT significantly reduced blood glucose levels in normoglycemic rats (p<0.05) two hours after administration, from 83±2 mg/dL to 57.39±1.7 mg/dL with the dose of 1250 mg/kg. given the highest reduction rate of 30.86%. In normoglycemic rats 30 minutes after oral glucose overload, the maximum reduction rate was observed with glibenclamide 5 mg / kg and calculated at 49.90% followed by 36.39%, for the extract at 1250 mg / kg. After 30 days of repeated oral administration, AECT produced a reduction on blood glucose levels (p<0.05) in type 2 diabetic rats. This reduction in blood sugar was much more expressed with the dose of 1250mg/kg (73.52±0.71 mg/dL) followed by metformin 38mg/kg (70.21±0.89 mg/dL) as the normal control with no significant difference (P < 0.05). Conclusion: These results show that the antidiabetic activity of AECT can be explained by insulin stimulating effect, also give support to the traditional use of this plant.                   Peer Review History: Received 11 May 2021; Revised 17 June; Accepted 27 June, Available online 15 July 2021 Academic Editor: Dr. Asia Selman Abdullah,  Al-Razi university, Department of Pharmacy, Yemen, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.  Received file:                Reviewer's Comments: Average Peer review marks at initial stage: 6.5/10 Average Peer review marks at publication stage: 8.0/10 Reviewer(s) detail: Dr. Terhemen Festus Swem, Department of Veterinary Physiology and Biochemistry, College of Veterinary Medicine, Federal University of Agriculture, Makurdi, Benue State, Nigeria, [email protected] Taha A.I.

Abstract Background:Cyclosporine-A has been regarded as an immunoregulatory and anti-inflammatory drug for the treatment of various immune inflammatory diseases. However, the effect of Cyclosporine-A on the retina of type 2 diabetic rats and the underlying mechanism remains to be elucidated. The objective of the present study was to investigate the effect and mechanism of Cyclosporine-A on diabetic retinopathy. Methods:Male Sprague-Dawley rats were established to type 2 diabetic model.After 6 weeks, diabetic rats and normal controls were intravitreally injected with Cs-A (42 ng/2 μL) to the left eye, and 2μL DMSO to the right eye for the control. Another part of normal wild-type rats was subjected to intravitreal injections into the left eyes with 5 μL PBS or HMGB-1 (5 ng/5 μL) or HMGB-1(5 ng/5 μL) plus Cs-A (42 ng/2 μL), respectively. Retinal morphological changes were observed with hematoxylin–eosin staining. Expressions of HMGB-1, IL-1β and TNF-α were detected by immunohistochemistry, ELISA or western blot. Results:Retinal expression levels of IL-1β and TNF-α were upregulated in type 2 diabetic rats and in normal rats with intravitreal injection of HMGB-1, which were attenuated by intravitreal Cs-A. Moreover, Cs-A decreased HMGB-1 expression in diabetic retina and relieved the retinopathy in type 2 diabetic rats. Conclusions:Intravitreal administration of Cs-A showed a protective effect on retina of diabetic rats, possibly by downregulating retinal expressions of IL-1β and TNF-α via the suppression of HMGB-1.

The present study investigated the possible cardioprotective effects of GLP1 and SGLT2i against diabetic cardiomyopathy (DCM) in type 2 diabetic rats and the possible underlying mechanisms. Methods: Thirty-two male Sprague Dawley rats were randomly subdivided into 4 equal groups: (a) control group, (b) DM group, type 2 diabetic rats with saline daily for 4 weeks, (c) DM + GLP1, as DM group with GLP1 analogue (liraglutide) at a dose of 75 µg/kg for 4 weeks, and (d) DM + SGLT2i as DM group with SGLT2 inhibitor (dapagliflozin) at a dose of 1 mg/kg for 4 weeks. By the end of treatment (4 weeks), serum blood glucose, homeostasis model assessment insulin resistance (HOMA-IR), insulin, and cardiac enzymes (LDH, CK-MB) were measured. Also, the cardiac histopathology, myocardial oxidative stress markers (malondialdehyde (MDA), glutathione (GSH) and CAT) and norepinephrine (NE), myocardial fibrosis, the expression of caspase-3, TGF-β, TNF-α, and tyrosine hydroxylase (TH) in myocardial tissues were measured. Results: T2DM caused significant increase in serum glucose, HOMA-IR, serum CK-MB, and LDH (p < 0.05). Also, DM caused significant myocardial damage and fibrosis; elevation of myocardial MDA; NE with upregulation of myocardial caspase-3, TNF-α, TGF-β, and TH; and significant decrease in serum insulin and myocardial GSH and CAT (p < 0.05). Administration of either GLP1 analog or SGLT2i caused a significant improvement in all studied parameters (p < 0.05). Conclusion: We concluded that both GLP1 and SGLT2i exhibited cardioprotective effects against DCM in T2DM, with the upper hand for SGLT2i. This might be due to attenuation of fibrosis, oxidative stress, apoptosis (caspase-3), sympathetic nerve activity, and inflammatory cytokines (TNF-α and TGF-β).
