Necrosis and apoptosis coexist in the thyroid during goitre development and involution, but little is known about their respective causes. To test the possible role of free radicals, we analysed separately necrosis and apoptosis in male Wistar rats with depressed or normal antioxidant protection. Vitamin E-deficient and -sufficient rats were made goitrous with perchlorate in drinking water; involution was induced by repeated injection of NaI, without or with methimazole. Increase of thyroid malondialdehyde concentration and decrease of glutathione peroxidase activity confirmed the depressed antioxidant protection in vitamin E-deficient rats. Plasma thyroxine and TSH levels were not modified. Necrosis (swollen cells) and apoptosis (pyknotic cells) were quantified on histological sections. In vitamin E-sufficient rats, dead cells were very rare in control thyroids, increased 3-fold in goitre and still further during involution. Necrotic epithelial cells predominated in the goitre and their number declined after iodide supplementation, without or with methimazole. In contrast, the number of apoptotic cells and the caspase-3 activity were increased in goitre and further increased after involution, with two-thirds of pyknotic cells being observed in the interstitium. Apoptosis was prevented by methimazole. Vitamin E deficiency significantly increased total cell death and epithelial cell necrosis and induced the occurrence of much cell debris in the follicular lumen during involution, with no modification of the apoptotic reaction. These results show that the type of cell death is differentially regulated during goitre development and involution: necrosis is related to the oxidative status of the cells, while apoptosis comes with iodine-induced involution.

Male reproductive functions could be affected at multiple levels due to dia-betes mellitus. Antioxidants vitamins have direct impact on improving male reproductive capacity. Our objective was to assess the efficiency of treat-ment with vitamin C and E in the case of whether diabetes mellitus is the cause of infertility or if infertile men suffer from diabetes by inducing diabe-tes on male Wistar rats. Adult male Wistar rats were divided into 5 groups of 6 animals each: a normoglycemic control. Other four groups were given a single dose of streptozotocin, and divided into: diabetic control, diabetic + 250 mg/kg/day of vitamin C, diabetic + 250 mg/kg/day of vitamin E, diabetic + 250 mg/kg/day of vitamin C + 250 mg/kg/day of vitamin E by gavage during 30 consecutive days. Animals were anesthetized, sacrificed to evaluate body and reproductive organ weights, plasma hormone levels, and semen quality. Compared to normoglycemic animals, diabetic rats showed reduced body weight (211.33 ± 8.70gr) and epididymis (1.35 ± 0.10 gr). The testis weight (3.10 ± 0.14 gr) and sperm count (2.72 ± 4.61 x 106) were maintained. A reduction of LH and testosterone levels (0.10 ± 0.00, and 0.25 ± 0.12) respec-tively. There was a significant increase (p<0.05) in the final body and epididy-mis weights, hormonal levels, and sperm count among diabetes vitamins treated groups as compared to the normoglycemic and hyperglycemic groups. Diabetes mellitus induces adverse effects on reproductive capacity. Antioxidant vitamins C and E improves sperm quality and increases hormonal levels.

Chlorambucil (4-[4-[bis(2-chloroethyl)amino]phenyl]butanoic acid) is an alkylating agent, indicated in chronic lymphocytic leukaemia. Kolaviron (KV), a biflavonoid complex fromGarcinia kola,and L-ascorbic acid (AA) are known to protect against oxidative damagein vivo. This study evaluates the protective capacity of KV and AA on chlorambucil-induced oxidative stress in the testes of rat. Twenty male Wistar rats (180–200 g) were randomized into four groups: I: control, II: chlorambucil (0.2 mg/kg b.w.), III: 0.2 mg/kg chlorambucil and 100 mg/kg KV, and IV: 0.2 mg/kg chlorambucil and 100 mg/kg AA. After 14 days of treatments, results indicated that chlorambucil caused significant reduction (P<0.05) in testicular vitamin C and glutathione by 32% and 39%, respectively, relative to control. Similarly, activities of testicular GST, SOD, and CAT reduced significantly by 48%, 47%, and 49%, respectively, in chlorambucil-treated rats relative to control. Testicular MDA and activities of ALP, LDH, and ACP were increased significantly by 53%, 51%, 64%, and 70%, respectively, in the chlorambucil-treated rat. However, cotreatment with KV and AA offered protection and restored the levels of vitamin C, GSH, and MDA as well as SOD, CAT, GST, ACP, ALP, and LDH activities. Overall, kolaviron and L-ascorbic acid protected against chlorambucil-induced damage in the testes of the rat.

AbstractThis experiment aimed to investigate the effect of dietary Nigella sativa on the cell-mediated immune response. Eighteen male Wistar rats were divided equally into a control group and treated groups that received black seeds at rates of 30 and 50 g/kg in the diet (Sa30 and Sa50 groups, respectively, for 30 days. The weight gain, feed intake, feed conversion ratio (FCR), and cell-mediated immune response were monitored after the injection of 0.1 mL of 10% phytohemagglutinin (PHA). The intumesce index, serum total antioxidant capacity (TAC), catalase (CAT), interleukin-12 (IL-12), gamma interferon (γ-IF) and tumor necrosis factor alpha (TNF-α) were determined. Histopathological examination and an immunohistochemistry analysis of splenic caspase-3 and CD8 were performed. Nigella sativa significantly improved the weight gain and FCR. Intumesce index of Sa50 group was significantly increased. Nigella sativa significantly increased TAC, CAT, IL-12, γ-IF and TNF-α. A histological examination of PHA-stimulated foot pads showed increased leukocyte infiltration and edema in a dose-dependent pattern. Splenic caspase-3 and CD8 showed significant decreases and increases, respectively, in the Sa30 and Sa50 groups. The results indicate that Nigella sativa seeds exhibit immunostimulatory function through their antioxidant potential, induction of cytokine production, promotion of CD8 expression and reduction of splenic apoptosis.

AbstractApproved medications for alcohol use disorder (AUD) display modest effect sizes. Pharmacotherapy aimed at the mechanism(s) by which ethanol activates the dopamine reward pathway may offer improved outcomes. Basal and ethanol-induced accumbal dopamine release in the rat involve glycine receptors (GlyR) in the nucleus accumbens (nAc). Glycine transporter 1 (GlyT-1) inhibitors, which raise extracellular glycine levels, have repeatedly been shown to decrease ethanol intake in the rat. To further explore the rational for elevating glycine levels in the treatment of AUD, this study examined accumbal extracellular glycine and dopamine levels and voluntary ethanol intake and preference in the rat, after systemic treatment with glycine. The effects of three different doses of glycine i.p. on accumbal glycine and dopamine levels were examined using in vivo microdialysis in Wistar rats. In addition, the effects of the intermediate dose of glycine on voluntary ethanol intake and preference were examined in a limited access two-bottle ethanol/water model in the rat. Systemic glycine treatment increased accumbal glycine levels in a dose-related manner, whereas accumbal dopamine levels were elevated in a subpopulation of animals, defined as dopamine responders. Ethanol intake and preference decreased after systemic glycine treatment. These results give further support to the concept of elevating central glycine levels to reduce ethanol intake and indicate that targeting the glycinergic system may represent a pharmacologic treatment principle for AUD.

AbstractAngiostrongylus cantonensis (AC) can cause severe eosinophilic meningitis or encephalitis in non-permissive hosts accompanied by apoptosis and necroptosis of brain cells. However, the explicit underlying molecular basis of apoptosis and necroptosis upon AC infection has not yet been elucidated. To determine the specific pathways of apoptosis and necroptosis upon AC infection, gene set enrichment analysis (GSEA) and protein–protein interaction (PPI) analysis for gene expression microarray (accession number: GSE159486) of mouse brain infected by AC revealed that TNF-α likely played a central role in the apoptosis and necroptosis in the context of AC infection, which was further confirmed via an in vivo rescue assay after treating with TNF-α inhibitor. The signalling axes involved in apoptosis and necroptosis were investigated via immunoprecipitation and immunoblotting. Immunofluorescence was used to identify the specific cells that underwent apoptosis or necroptosis. The results showed that TNF-α induced apoptosis of astrocytes through the RIP1/FADD/Caspase-8 axis and induced necroptosis of neurons by the RIP3/MLKL signalling pathway. In addition, in vitro assay revealed that TNF-α secretion by microglia increased upon LSA stimulation and caused necroptosis of neurons. The present study provided the first evidence that TNF-α was secreted by microglia stimulated by AC infection, which caused cell death via parallel pathways of astrocyte apoptosis (mediated by the RIP1/FADD/caspase-8 axis) and neuron necroptosis (driven by the RIP3/MLKL complex). Our research comprehensively elucidated the mechanism of cell death after AC infection and provided new insight into targeting TNF-α signalling as a therapeutic strategy for CNS injury.
