Olanzapine is an antipsychotic drug effective in the treatment of stress-associated psychiatric illnesses, but its effect on the spleen remains unclear. Vitamin C is essential for the optimum function of the immune system. We aim to investigate the effect of Olanzapine on spleen structures and to assess the protective effect of vitamin C. Forty adult male albino rats were divided into four groups: group (I), a control; group (II), rats were given vitamin C at 40 mg/kg body weight; group (III), rats were given Olanzapine at 2 mg/kg body weight; and group (IV), rats were given vitamin C and Olanzapine at the same dose of group (II) and group (III) for one month. The hematoxylin and eosin (H&E) of the olanzapine treated group showed focal areas of cellular depletion and a decrease in the size of the white pulp. The red pulp was expanded and showed marked congestion and dilatation of blood sinusoids. Cluster of differentiation 3 (CD3) was significantly reduced, however both tumor necrosis factor alpha (TNF-α), and vascular endothelial growth factor (VEGF) were significantly higher. The administration of vitamin C repaired structural and immunohistochemical changes via increased CD3 and decreased TNF-α and VEGF. Therefore, the oxidative and the inflammatory pathways may be the possible mechanisms underlying olanzapine immunotoxicity. Vitamin C exerted immune modulator and antioxidant effects against olanzapine.

Background: Nicotine is the active alkaloid in cigarettes. It was reported that tobacco smoking has many hazards; one of these hazards is the effect on the cognitive function of the prefrontal cortex. The aim of our study is to investigate the antioxidant effects of ginger, cinnamon oils, and their combination on morphological changes in the prefrontal cortex that were induced by nicotine. Materials and methods: Fifty adult male albino rats were divided into five groups: group I (control group), group II (nicotine), group III (nicotine + cinnamon), group IV (nicotine + ginger), and group V (nicotine + cinnamon + ginger). The coronal sections from the anterior part of the rat brain at the site of prefrontal cortex were examined by light microscope for (H&E and immunohistochemical staining with TNF-α and GFAP), while the ultrastructure morphology was examined by transmission electron microscopy. Levels of the oxidative stress markers (MDA, GSH) in the rats’ brain tissue homogenate were biochemically assessed. Results: Compared to the control group, the rats that were treated with nicotine (group II) showed a significant oxidative stress in the form of marked elevation of MDA and decrease in GSH, apoptotic changes especially in the pyramidal cells in the form of neuronal cell degeneration and pyknosis, and an elevation in the inflammatory marker TNF-α and GFAP expressions. These changes were observed to a lesser degree in rat group (III) and group (IV), while there was a marked improvement achieved by the combined usage of cinnamon and ginger oils, together compared to the nicotine group. Conclusions: Ginger and cinnamon are powerful antioxidants which ameliorate the degenerative and oxidative effects produced by nicotine on a rat’s prefrontal cortex.

BACKGROUND: Sofosbuvir (SOF) was published in 2013 as a part of first-line treatments for hepatitis C virus (HCV); it has activity against all genotypes with extrahepatic adverse effects have recently arisen. AIM: Investigating sofosbuvir-induced alterations in the rat submandibular salivary gland (SMSG). METHODS: A group of 80 adult albino rats weighing about ± 150 gm were used in the experiment. The rats were divided into 3 groups: Group I (control group) received distilled water, Group II (experimental group) divided into 2 subgroups and received SOF 40 mg/kg/day dissolved in distilled water for 1 and 3 months and Group III (recovery group) allowed for 1 month of recovery after SOF withdrawal. All animals were sacrificed; the SMSG was dissected, and specimens were examined histologically and ultra-structurally. RESULTS: Compared to Group I, Group II subgroup (1) showed acinar and ductal vacuolisation, discontinuity of the epithelial lining associated with retained secretion and congested blood vessels. These changes were found to be exaggerated in the subgroup (2) accompanied by acinar and ductal shrinkage, interstitial oedema, haemorrhage, chronic inflammatory cells infiltration and loss of gland compactness. Amelioration of the histological changes was detected in Group III after SOF withdrawal. The ultrastructural examination confirmed the histological results. CONCLUSION: SOF had induced apparent alterations in the structure and ultrastructure of SMSG. The SOF-induced alterations were time-dependent, attributed mainly to mitochondrial toxicity and partially ameliorated by its withdrawal.

The effect of environmental conditions on hatching indices of poultry eggs is sufficiently important that new methods for their improvement are sought, among others through exposing the eggs during hatching to an artificially generated magnetic field of variable frequency. Hatching eggs in this study came from Pharaoh quail in the 4th month of laying. The flock was kept under optimum microclimate conditions and fed a complete feed mix containing 21% total protein and 11.7 MJ ME. The eggs (n = 150), after weighing, were divided into 3 groups equal in respect of numbers: control (I) and two experimental (II and III). The eggs of group II and III were exposed to the action of variable magnetic field of the same intensity but different times of application. The highest percentage of dead embryos during incubation in relation to fertilised eggs was found in control group (11.36%), while the smallest was from group II (4.17%). The highest value of hatching indices calculated in relation to fertilised eggs was found in group II (91.6%), while the smallest was in group III (83.7%) with 86.3% in control group. The results point to the possibility of increasing egg hatchability indices through the use of additional variable magnetic field. The chicks hatched from eggs exposed to the action of this experimental agent had similar body weight. The average weight of one-day-old chicks ranged from 7.82 g (group II) to 8.05 g (group III). In the last week of rearing, mean body weight in both sexes was similar and ranged from 168 (group I) to 172 g (group III) in males, and from 186 g (group I) to 199 g (group III) in females; these differences were not statistically significant. The females of group III reached sexual maturity at 41 days, this being one and three days (non-significantly) earlier than birds in group I and II.

Relationship between thyroid dysfunction and periodontal disease has been mediated through an immune response. Cytokines are implicated in the initiation, consequences of immune response and a crucial role in the pathogenesis of thyroid disease, directly target thyroid follicular cells; and in the development and progression of periodontitis. This study aimed to detect cytokines levels which known to be associated with periodontitis in serum and saliva, to test the hypothesis that hypothyroidism influences the levels of biomarkers of periodontitis. Samples were collected from sixty patients with hypothyroid age ranged (20-64) years, thirty of patients were without periodontitis (group I) and 30 with periodontal disease (II); moreover, 30 subjects considered as control (group III) with age (20-53) years. Detection of cytokines was performed by ELISA. The results showed a significant elevation in serum and salivary levels of IL-1β (P<0.001) among patients’ groups (I and II) as compared to group III, as well IL-1β increase significantly in group II (P<0.001) than in group I and also than group III. There are non-significant differences (P>0.05) in serum level of IL-6 and TNF-α and salivary levels of TNF-α among all study groups. Nevertheless, the salivary level of IL-6 is increased significantly (P<0.05) in group II as compared with group I and group III, and their non-significant differences (P<0.05) between groups I and III. The present finding proposed that hypothyroidism might encourage periodontitis development; as well as serum and salivary levels of IL-1β, with salivary IL-6 may represent important biomarkers for the early detection of periodontitis in hypothyroid patients.

Myopathy is one of the side effects of colchicine, manifested as pain, dysfunction, and weakness of muscles. Ginseng extract antioxidant  and anti-inflammatory activities have been reported in muscular tissue. This study was conducted to investigate whether administration of ginseng ameliorates colchicine-induced skeletal muscles damage in adult male albino rats. Forty adult male albino rats were randomly  divided into four groups (ten/group) – Group I (control group): rats received normal diet and orally given normal saline, Group II: ginseng extract was administered via oral gavage daily for one month at the doses of 300 mg/kg, Group III (Colchicine treated group): rats were  given colchicine (50 μg/kg/day) via oral gavage for one month, and Group IV: concomitant administration of Ginseng and colchicine for one month. Serum creatine kinase (CK) levels were measured, and skeletal muscles specimens were processed for light and electron microscopic examination. Administration of colchicine (group III) showed elevated serum CK, and histologically myofibrillar disarray foci together with cellular infiltration and edema. Group IV showed reduction in most of those manifestations. Concomitant administration of ginseng with colchicine ameliorated most of the symptoms related to colchicine induced-myopathy.

This study was an attempt to delineate the effect of allethrin based mosquito coil exposure on male fertility of wistar albino rats. This also includes two months of discontinuation of exposure to know whether there is any reversibility of changes. We also studied the role of an antioxidant (Vitamin C) in ameliorating the effect caused by the coil.The animals in our study were randomized into four groups: group I served as control rats; group II, III and IV received mosquito coil smoke 8 hours a day, 7 days a week for 12 week. Group IV rats co-administered oral supplementation of Vit. C (20 mg/kg body weight) once in a day for the same time period while group III animals were further kept for 8 weeks without any exposure to demonstrate withdrawal effect. Mean testicular weight was maximum in Group IV(1.83±0.30 gm) followed by group I(1.56±0.19gms), group III(1.22±0.42 gms) and group II(0.64±0.09 gm). Mean sperm count ranged from 83.75±9.61 units in Group II to 100.0±16.68 units in Group III, 130.7±14.14 units in Group IV and 157.7±7.92 units (Group I). Mean % abnormal sperm morphology was maximum in Group II (36.95±7.87%) followed by Group III (30.66±9.59%), Group IV (11.97±2.74%) and Group I (5.37±1.28%). Statistically, this difference was significant (p<0.001). This study demonstrates different types of abnormal sperm morphology. This study has its own merit that it also depicts the possible improvement after discontinuation of exposure and vitamin C supplementation.

Thyroxine hormone (T4) was one of the hormones related to metabolism rate. Animal transportation could be stressor interfering metabolism. Sargassum crasifoium was one of brown algae species that contained some important nutrients and also flavonoids. The study aimed at finding out the effect of the Sargassum on the decrase in thyroxine hormone and body weight loss. It used 9 Javanese Randu goats that were classified into 3 treatment groups. Group I served as control, Group II was treated with 450 mg/kg BW of Sargassum estract and Group III was treated with vitamin B1. All of the goats were transported for 12 hours using pickup truck at the speed of 60 km/hour. Blood samples were drawn before the transportation, during loading, 6 hours after the transportation and at the end of the transportation, while the body weight of the goats was weighed before and after the transportation. The results of the study showed that the T4 hormone decreased in the Group I and increased in the Group III during the transportation, while it was stable in the Group II. The biggest percentage of the body weight loss took place to the Group III (0.13%), while the smallest percentage took place to the Group II (0.063%). Statistical analysis showed that the Sargassum extract did not have any significant effect (p>0.05) on both the thyroxine hormone and the body weight loss during the transportation. Based on the results of the study it could be concluded that the Sargassum extract could stabilize the thyroxine hormone during the transportation so that it could prevent the body weight loss
