Scientific Rationale

Diabetes is characterized by hyperglycaemia with alterations of lipid parameters. The effects of Aloe vera (A.V) gel extract on lipid profiles of streptozotocin-induced diabetic rats were investigated. Seventy-two male albino rats were randomly divided into six groups of 12 rats each; control, diabetic control, 4 ml/kg and 8 ml/kg body weight (b.w.) A.V, 10 mg/kg b.w. glibenclimide and non-diabetic 8 ml/kg b.w. A.V groups. They were treated for 14 and 28 days. The plasma and HDL lipid profiles (triacylglycerols, cholesterol and phospholipids) of the diabetic rats were significantly (p<0.05) increased, while those of the VLDL+LDL, RBC, RBC membrane and organs were observed to be significantly (p<0.05) reduced, when compared to the control after 14 and 28 days of treatment. A.V gel extract significantly (p<0.05) ameliorated the disruptions observed in the lipid profiles of the diabetic and thus provide a scientific rationale for the use of Aloe vera as a therapeutic agent.Bangladesh J Med Biochem 2016; 9(1): 11-26

N-acetylcysteine (NAC) and melatonin were reported to exert protective effects on testicular tissues. Thus, this study aimed to determine which of these is more efficient against obesity-induced testicular dysfunction in albino rats. Total 32 adult male rats (195 ± 10g) were divided into 4 groups: control, obese rats fed a high-fat diet (HFD), HFD+ NAC (150 mg/kg/d, ip) and HFD+melatonin (10 mg/kg/d, ip) group, for five weeks. Testes and epididymis were weighted. Lipid profile, pituitary-testicular hormones, tumor necrosis factor-α (TNFα), epididymal sperm parameters, testicular oxidant/antioxidant system, testicular and the epididymal histopathology, immunohistochemical localization for androgen receptors (AR) and Bax reaction were analyzed. Administration of NAC or melatonin significantly improved the lipid parameters, gonadal hormones, TNFα level, sperm count and abnormal morphology, oxidant/antioxidant system and the absolute testicular and epididymal mass with an enhancement of testicular architecture, AR expression and apoptosis as compared to that in the obese group. Additionally, as compared to the NAC group, the melanin group had significantly reduced BMI, total cholesterol, triglyceride, and TNFα and increased testosterone, sperm count, motility, superoxide-dismutase activity, mitigated histo-morphometrical changes, BAX expression, and increased testicular AR expression. Therefore, melatonin was more efficient than NAC in affording fortification against HFD-induced testicular dysfunction

Objective: The aim of this study was to investigate the effect of ethanol extracts of stem and leaf of Bacolepis nervosa as antihyperglycemic, anti-hyperlipidemic and antioxidant activity in alloxan-induced diabetic rats. Methods: Diabetes was induced in wistar albino rats by administration of alloxan monohydrate (150 mg/kg). The ethanol extract of B. nervosa leaf and stem at a dose of 150 and 300 mg/kg body weight was administrated at a single dose per day to diabetes-induced rats for a period of 14 d. The effect of ethanol extract of B. nervosa leaf and stem on blood glucose, insulin, urea, creatinine, HbA1C, serum protein, albumin, globulin, serum enzymes, serum lipid profiles, lipid peroxidase (LPO) and antioxidant enzymes like superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and reduced glutathione (GSH) were measured in the diabetic rats.Results: The ethanol extract of B. nervosa stem and leaf elicited significant reduction in blood glucose (p<0.001), serum enzymes (SGPT, SGOT, ALP) (p<0.01), lipid parameters (TC, TG, VLDL-LDL, PL) (p<0.01) except HDL-C and significantly increased insulin (p<0.01), HDL-C (p<0.05),, GPx, GSH, SOD and CAT (p<0.05) at the dose of 300 mg/kg when compared with the diabetic-induced control.Conclusion: From the above results, it is concluded that ethanol extracts of B. nervosa leaf and stem possesses significant antihyperglycemic, antihyperlipidemic and antioxidant effect in alloxan induced diabetic rats.

It is well known that the rat adrenal zona glomerulosa steroidogenic activity is controlled by the renin-angiotensin system. The ultrastructural changes in the rat zona glomerulosa cells induced by renovascular hypertension were described previously, but as far as we are aware no correlated biochemical and morphometric investigations were performed.Twenty adult male albino rats were divided into 2 experimental groups. One group was subjected to restriction of blood flow to the left kidney by the application of a silver clip about the left renal artery. The other group was sham-operated and served as a control. Renovascular hypertension developed in about 10 days: sistolic blood pressure averaged 165 ± 6. 4 mmHg, whereas it was about 110 ± 3. 8 mmHg in the control animals. The hypertensive and control rats were sacrificed 20 days after the operation. The blood was collected and plasma renin activity was determined by radioimmunological methods. The aldosterone concentration was radioimmunologically assayed both in the plasma and in the homogenate of the left capsular adrenal gland.

Cell Components

The fine structure of the Harderian gland has been described in some animal species (hamster, rabbit, mouse, domestic fowl and albino rats). There are only two reports in the literature dealing on the ultrastructure of rat Harderian gland in adult animals. In one of them the author describes the myoepithelial cells in methacrylate-embbeded tissue, and the other deals with the maturation of the acinar cells and the formation of the secretory droplets. The aim of the present work is to analize the relationships among the acinar cell components and to describe the two types of cells located at the perifery of the acini.

Methodology has been introduced recently which allows transmission and scanning electron microscopy of cell fine structure in semi-thin sections unencumbered by an embedding medium. Images obtained from these “resinless” sections show a three-dimensional lattice of microtrabeculfee contiguous with cytoskeletal structures and membrane-bounded cell organelles. Visualization of these structures, especially of the matiiDra-nous components, can be facilitated by employing tannic acid in the fixation step and dessicator drying, as reported here.Albino rats were fixed by vascular perfusion with 2% glutaraldehyde or 1.5% depolymerized paraformaldehyde plus 2.5% glutaraldehyde in 0.1M sodium cacodylate (pH 7.4). Tissues were removed and minced in the fixative and stored overnight in fixative containing 4% tannic acid. The tissues were rinsed in buffer (0.2M cacodylate), exposed to 1% buffered osmium tetroxide, dehydrated in ethyl alcohol, and embedded in pure polyethylene glycol-6000 (PEG). Sections were cut on glass knives with a Sorvall MT-1 microtome and mounted onto poly-L-lysine, formvar-carbon coated grids while submerged in a solution of 95% ethanol containing 5% PEG.
