Many traditional systems of medicines employ herbal drugs for the hepatoprotection. Aim of the study was designed to evaluate the hepatoprotective potential of polyherbal formulation against alcohol induced hepatotoxicity in wistar albino rats. Group I animals were treated with 1% CMC for 18 days. Group II, III and IV animals were treated with 1% CMC, polyherbal formulation 180mg/kg/day and silymarin 100mg/kg/day respectively for 18 days and then orally administration with ethanol 3.76 g/kg/day simultaneously for 18 days. After 24 hours of last dosing, the blood was obtained through retro-orbital plexus under light anaesthesia and the animals were sacrificed.  Hepatoprotective potential was assessed by various biochemical parameters such as AST, ALT, ALP, LDH, bilirubin, cholesterol, TG and thiopentone sodium induced sleep time. Group III rats showed significant (p<0.01) decrease in AST, ALT, ALP, LDH, bilirubin, cholesterol, TG, liver weight(wt.) and relative liver wt. levels while significant (p<0.01) increase in TP levels as compared to group II rats. Hepatoprotective potential of polyherbal formulation 180mg/kg/day was comparable to that of standard drug silymarin 100mg/kg/day. Results of the study were well supported by histopathological observations. This study confirms that polyherbal formulation possesses hepatoprotective potential comparable to that of standard drug silymarin as it exhibited comparable protective potential against PCM induced hepatotoxicity in albino rats.

Background: To find out a new agent with a high therapeutic index for the treatment of anxiety, an indigenous medicinal plant Eucalyptus terteticornis was screened for its effect on anxiety in experimental animal model.Methods: Thirty six adult Wistar albino rats of both sexes weighing 175-200g were divided into three groups: Group I: DMSO 10% (0.1ml/200g), Group II: hexane extract of leaves of Eucalyptus terteticornis (ETHE) (100mg/kg/body weight), Group III: Diazepam (1mg/kg orally). All test compounds were administered orally for ten days. On tenth day, after one hour of test compounds administration, Wistar rats were taken for elevated plus maze (EPM) and light dark arena (LDA) tests. Statistical comparisons among the groups were performed by One-way analysis of variance (ANOVA) followed by Tukey Krammer test.Results: The results showed that ETHE treated animals (Group II) significantly (p <0.001) increased the time spent in open arms of EPM and in bright arena of LDA on comparing with normal (Group I).Conclusions: The anti-anxiety activity of Eucalyptus terteticornis can be due to its effect on brain neurotransmitters or due to antioxidant property.

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.

This study is an attempt to evaluate the hepatoprotective activity ofTabernaemontana divaricataagainst DEN and Fe NTA induced liver necrosis in rats. Ethanolic extract of the whole plant ofTabernaemontana divaricataat doses of 200 and 400 mg/kg body weight and 5-fluorouracil (standard drug) was orally administered to male Wistar Albino rats once daily for 24 weeks, simultaneously treated with the carcinogen DEN and Fe NTA. In simultaneously treated animals, the plant extract significantly decreased the levels of uric acid, bilirubin, AST, ALT, and ALP in serum and increased the levels of liver marker enzymes in liver. Treatment with the extracts resulted in a significant increase in the levels of antioxidants accompanied by a marked reduction in the levels of malondialdehyde when compared to DEN and Fe NTA treated group. When compared with 200 mg/kg bw rats, 400 mg/kg bw rats and 5-fluorouracil treated rats showed better results in all the parameters. The histopathological studies confirmed the protective effects of extract against DEN and Fe NTA induced liver necrosis. Thus, it could be concluded that the use ofTabernaemontana divaricataextract in the treatment of carcinogen induced hepatic necrosis.

Withaferin-A (WA) was evaluated for its neuroprotective efficacy on the dopamine (DA) neurons of the substantia nigra (SN) and striatum (ST) in aged rats. Wistar albino rats were divided into group I, young (3 months old); group II, aged (24 months old); group III, aged rats supplemented with WA (50 mg/kg bodyweight once per day for 30 days), and group IV, young rats supplemented with WA (50 mg/kg bodyweight). At the end of the experiment period, the animals were subjected to various motor behavior analyses, and were sacrificed by transcardial perfusion. The brains were dissected out and subjected to various analyses, including histological, histomorphometrical, and immunolocalization of the tyrosine hydroxylase (TH) enzyme. The data of rotarod analysis (p < 0.001) showed a significant motor impairment in aged rats (number of falls 10.2 ± 0.86) and reduction in retention time (31.23 ± 2.56 s) compared to young controls (2.41 ± 0.35 and 84.05 ± 5.15 s). The stride length was significantly reduced (p < 0.001) in aged rats (4.21 ± 0.57 and 4.38 ± 0.61 cm) when compared to young control rats (6.98 ± 0.25 and 7.13 ± 0.70 cm). The histomorphometric data of the aged animals showed a significant reduction in the neuronal diameter (p < 0.001), density (p < 0.001), and volume (p < 0.001) in the SN of aged rats when compared to young rats. Immunohistology demonstrated a marked reduction in the levels of TH enzyme in both the SN and ST of aged animals when compared to young rats. Both structural and functional impairments were reversed in the aged animals after the supplementation of WA (p < 0.001). The present study clearly indicates that WA attenuates the ageing-mediated motor degenerative changes in the SN and ST of aged rats and ascertains its neuroprotective potential.

Three groups of 16 albino rats were fed for 45 days, group I, a normal diet of pellets containing 3.5% fat; group II, a diet containing 17% fat in the form of oil; and group III, a diet containing 17% fat in the form of lard. On exposure to cold, the drop of rectal temperature in group I was faster and more pronounced than in group II or group III. It was shown that the larger amount of fat accumulated in the animals fed a high fat diet could not explain, either as a source of energy reserves or as an insulator, the superiority of these diets in maintaining the rectal temperatures at higher levels in the cold. It is postulated that prefeeding of a high fat diet induces changes in the organism which permit higher sustained rates of heat production in the cold.

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.

The aim of this study was to investigate the antioxidant effects of tempol on ovarian ischemia–reperfusion (I/R) injury in rats. Forty female Wistar albino rats were randomly divided into 5 groups: Group I, sham; Group II, ischemia (I); Group III, I/R; Group IV, I/R + tempol 30 mg/kg i.p; Group V, I/R + tempol 50 mg/kg i.p. Oxidative stress index (OSI) was significantly higher in the ischemia group and the I/R group than in the sham group. Catalase levels were significantly lower in the I/R group than in the I/R + tempol 30 mg/kg i.p. and the I/R + tempol 50 mg/kg i.p. groups. Glutathione peroxidase levels were lower in the I/R group than in the I/R + tempol 30 mg/kg i.p. and the I/R + tempol 50 mg/kg i.p. groups. MDA levels were significantly lower in the I/R + tempol 30 mg/kg i.p. group and the I/R + tempol 50 mg/kg i.p. group than in the I/R group. The levels of the histopathological parameters were significantly decreased in the I/R + tempol 50 mg/kg i.p. group compared with the I/R group. Tempol can be used for reducing ovarian I/R injury.

Histological Results

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.
