Hyperlipidemia represents a major risk factor for cardiovascular diseases leading to myocardial injury. The present study aimed to illustrate the myocardial injury induced in a diabetic hyperlipidemic rat model and the effect of vitamin D3, 10-DHGD intake either individually or in combination form. Male albino rats were selected for the study, received alloxan, hypercholesterolemic diet, and categorized into four groups. The first one (DHC), received hypercholesterolemic diet only and referred to as control. The remaining groups (2, 3, 4) received vitamin D3, 10-DHGD, and combination of both, respectively. Certain biomarkers that were selected for MI evaluation included blood glucose, lipogram pattern, Copeptin, C-reactive protein, myeloperoxidase, heart fatty acid-binding protein, and histopathological changes in myocardium and aorta. Vitamin D3 and 10-DHGD intake induced significant hypoglycemic, hypolipidemic effects, decreased inflammation, and MI biomarkers. Decreased myocardial vacuoles, foam cells, and intimal lesions were also observed compared to DHC. Their combination intake induced more marked reduction in all biomarkers and showed a histopathological pattern similar to normal features of myocardium and aorta. Our findings suggest the therapeutic roles of vitamin D3, 10-DHGD, and their combination against myocardial injury in diabetic hyperlipidemic rats. Impact statement Hyperlipidemia represents a major risk factor for cardiovascular diseases leading to myocardial injury (MI). The present study aimed to illustrate the pattern of myocardial injury induced in diabetic hyperlipidemic rat model and the effect of vitamin D3, 10-dehydrogingerdione (10-DHGD) intake either individually or in combination form.

Abstract Objectives The aim of this research was to study the intensity of cytokeratin 17 (CK17) in the parenchymal elements of rat’s submandibular salivary glands subjected to fractionated radiotherapy regimen that used for treatment of head and neck malignancy. Materials and Methods Twenty male albino rats were divided into two equal groups (normal and irradiated). The irradiated group received a radiation dose of 5 Grays daily for 5 days using therapeutic X-ray beam. Six months later, submandibular gland was dissected out and prepared for both histological and immunohistochemical studies. Results Submandibular gland of irradiated group showed two different types of histological alterations. The first alteration showed severe gland atrophy replaced by either fibrous or fatty tissues. In some sections, the gland exhibited proliferating activity in the form of profuse amounts of mitotic figures. Immunohistochemical examination of control glands displayed a mild cytoplasmic expression of CK17 of duct cells as well as serous acini. The staining pattern was either diffused or concentrated at the basal part of the cell with negative expression at its apical part. Statistical Analysis Expression of CK17 in submandibular gland of irradiated group displayed a highly significant differences (P < 0.001) in both intercalated and striated ducts. Many serous acini displayed a highly significant differences (P < 0.001) whereas, mucous acini were negatively stained. Conclusions The intensity and diffusion of CK17 expression in our results foretell the pathological effect of radiotherapy on the intermediate filaments of salivary gland parenchyma that interfered with production and/or secretion of saliva leading to xerostomia.

The Impact

The gravity of the impact of drug induced nephrotoxicity is more prominent in society. The present study was undertaken to evaluate the potential of hydroalcoholic extract of seeds of Sorghum bicolor against cisplatin and doxorubicin- induced nephrotoxicity in Wistar albino rats. The nephrotoxicity was modeled by intraperitoneal injection of cisplatin (5 mg/kg b.w.) in cisplatin model and doxorubicin (15 mg/kg b.w.) in doxorubicin-induced model in rats. Nephroprotection of hydroalcoholic extract of seeds of S. bicolor was evaluated at two different doses of 200 and 400mg/kg b.w. The nephroprotective activity was assessed by the determination of various serum and urinary parameters, anti-oxidant studies, histological and immunohistochemical studies. The results indicated that injection of cisplatin and doxorubicin led to marked nephrotoxicity in animals. Treatment with extract in cisplatin-induced model resulted in significant nephroprotective activity in a curative regimen whereas in prophylactic regimen the extract prevented the induction of nephrotoxicity only up to a considerable level. But the extract failed to attenuate the doxorubicin induced nephrotoxicity, as evident by biochemical, histological and immunohistochemical studies. From the findings, it is concluded that the seeds of S. bicolor can be used as a novel approach in the treatment of cisplatin-induced nephrotoxicity.

The effect of vitamin D on cardiac dysfunction after menopause is still under investigation. Therefore, we investigated the effect of vitamin D3 on cardiac apoptotic and structural changes in ovariectomized rats. Forty adult female albino rats were divided into 4 equal groups: sham rats, sham rats treated with vitamin D3, ovariectomized rats, and ovariectomized rats treated with vitamin D3 (500 IU/kg per day for 6 weeks, orally). Body mass, blood pressure, heart rate, and whole heart mass (WHM) were measured. Serum soluble receptors of advanced glycation end products (sRAGE), C-reactive protein, malondialdehyde, and total antioxidant capacity were estimated. Cardiac sections were stained with haematoxylin–eosin and Masson’s trichrome stain. Fas and FasL apoptosis-related proteins were detected by immunohistochemistry. Vitamin D3 treatment significantly decreased ovariectomy-induced cardiac Fas and FasL apoptosis-related proteins, whole heart mass, body mass, C-reactive protein, and malondialdehyde accompanied by decreased inflammation and reduced collagen deposition between cardiac muscle fibres. However, vitamin D3 significantly increased total antioxidant capacity and sRAGE in ovariectomized and sham treated groups. Our findings suggest that vitamin D3 treatment can prevent ovariectomy-induced cardiac structural and apoptotic changes in rats via increasing sRAGE and antioxidant activity. Our results suggest that vitamin D3 has therapeutic effect against postmenopausal cardiovascular disease.
