Parkinson’s disease (PD) is a common neurodegenerative disease characterized by progressive and selective loss of dopaminergic neurons in the SNpc that provide innervations in the striatum. The present work was focused on the neuroprotective effect of fish oil (Omega-3 fatty acids) against experimentally (1-Methyl-4-Phenyl-1,2,3,6 tetrahydropyridine) induced Parkinson’s disease in mice, by analyzing the behavioural studies. Rota rod test, Hang test, measurement of fore paw stride length during walking test and Photo-actometer tests proved that 5% and 10% fish oil in mice improved the performance against MPTP administration and the results were significant (p<0.05). Compared to the control group 5% fish oil treated group shows improved behavioural activity – Rota rod test 71%; Hang test 70%, measurement of fore paw stride length during walking test 34% and Photo-actometer tests 14%. The 10% fish oil treated group shows Rota rod test 86%; Hang test 87%, measurement of fore paw stride length during walking test 64% and Photo-actometer tests 18.45%. The study evidence that fish oil is a neuroprotective against MPTP induced in mice.

The present study is carried out to investigate the anti-inflammatory potential of Ethanolic extract of Cissus Pallida (EECP). Anti-inflammatory activity was evaluated by using Egg Albumin, Turpentine Oil & Formaldehyde as phlogistic agents. The animals were treated with doses 200mg/kg and 400mg/kg of extract and Diclofenac Sodium at a dose of 10mg/kg is used as a standard drug. The EECP showed a significant anti-inflammatory activity in a dose dependent manner in all the models when compared with the standard treatment. The extract (400mg/kg) exhibited maximum anti-inflammatory activity i.e., 67.46%, 68.75%, 69.43% (P<0.001) than the standard Diclofenac 64.50%, 65.28%, 64.77% in Egg albumin, Turpentine oil and Formaldehyde induced methods respectively. Based on the above results, we conclude that the EECP has significant anti-inflammatory activity and might prove efficacious for further design and development of agents with significant biological activity.

Carbon tetrachloride (CCl4) is a well-known hepatocyte-destructive agent. Commiphora mukul is a medicinal plant found to be effective in the treatment of a variety of disorders. Aim of the work is to study the effect of Commiphora extract on liver injury induced by the administration of CCl4 in rats. Forty adult male albino rats were divided randomly into four groups. Group I (control group), group II (received CCl4 for 2 weeks), and group III and group IV, which received 250 and 500 mg/kg, respectively, of Commiphora extract orally before the administration of CCl4. Two weeks after the administrations of CCl4, animals were killed, and the livers were removed and processed for histological and electron microscopic examination. Liver functions were measured. The results revealed that a low dose of Commiphora extract did not lead to any improvement; while a high dose of Commiphora showed its potential to protect against CCI4 induced hepatotoxicity by controlling the serum alanine aminotransferase and aspartate amino transferase (ALT and AST) levels and alkaline phosphatase enzymes (ALP) and also hepatic lobules regenerate to their normal architecture with proliferating bile ductules in the portal tract. Some hepatic lobules still showed vacuolation and necrosis of their hepatocytes. It could be concluded that, Higher doses of Commiphora extract protects against CCl4-induced liver injury.

Paracetamol, the most commonly sold over-the-counter antipyretic analgesic, is generally considered harmless at therapeutic doses. However, paracetamol overdose causes severe and sometimes fatal hepatic damage in humans and experimental animals. This study was undertaken to examine the effects of Zingiber Officinale (ginger) powder on paracetamol induced hepatotoxicity in rats. Rats were given ginger 1% orally in the diet 7 days before induction of hepatotoxicity of paracetamol (1g/kg bwt) orally for 21 days. Paracetamol induced severe liver damage as assessed by increased serum liver marker enzymes, hypoalbuminemia with hyperglobulinemia. Paracetamol induced hepatic lipid peroxidation with reduction in reduced glutathione and antioxidant enzymes. Also, paracetamol caused changes in serum lipid profile. Unfortunately, away from general notion, ginger did not protect paracetamol induced hepatic injuries but potentiate the toxic effects of paracetamol on liver as evident by highly increase in serum globulin fractions with decreased serum albumin, increased serum activities of AST, LDH, ALP and GGT, reduced hepatic activities of antioxidant enzymes (GST, GR and GPX) and reduced glutathione level. In conclusion, ginger fails to protect rats against paracetamol induced chronic hepatotoxicity but enhance its adverse effects on liver.

Altered monoamines metabolism has been reported in hepatic encephalopathy (HE). In order to evaluate this thioacetamide (TAA) was administered to induce hepatic encephalopathy due to fulminant hepatic failure in rats. Methods: Female Albino Wistar rats (200-250 gm body wt) were selected and divided into two groups (n=6 in each group). Saline plus saline (controls) and TAA plus saline .TAA at a dose of 550 mg/kg was injected for two consecutive days in TAA plus saline treated rats. Brain concentrations of indoleamines, dopamine and their metabolites were measured by HPLC-EC. Brain concentrations of 5-hydroxy tryptamine (5-HT) were not significant. Whereas, its precursor Tryptophan (TRP) in the brain was significant (p<0.05), its metabolite 5-hydroxy indole acetic acid (5-HIAA) was significantly increased in TAA plus saline treated rats when compared to controls (p<0.01). Similarly concentrations of Dopamine (DA) were not increased in the brain. However, its metabolites dihydroxy phenyl acetic acid (DOPAC) and homo vanilinic Acid (HVA) was significantly increased in TAA plus saline (p<0.01). In plasma, TRP level was increased in TAA plus saline treated rats (p<0.05). Liver TRP levels were decreased in TAA plus saline treated rats when compared to controls but this decreased was insignificant. Liver total TRP and TRP pyrrolase apo enzyme activity were significantly decreased in TAA plus saline treated rats when compared to controls (p<0.05). Food intake was decreased on day 1 and on day 2 in TAA plus saline treated rats when compared to controls (p<0.05). Water intake was significantly decreased on day 1and on day 2 in when compared to controls (p<0.01). The results of this study show that an increased concentration of TRP, 5-HIAA and HVA, suggesting an increased turn over of 5-HT and DA in TAA plus saline treated rats.

We examined the association of elevated cadmium exposure with chronic kidney disease (CKD), increased oxidative stress and oxidative DNA damage in a total of 129 study residents 13 cadmium-contaminated villages. In bivariate correlation, elevated urinary cadmium excretion was significantly correlated with creatinine, N-acetyl-β-D-glucosaminidase, glomerular filtration rate (GFR), malondialdehyde, 8-hydroxy-2’-deoxyguanosine (8-OHdG) and total antioxidant level. Overall findings showed that elevated urinary cadmium excretion appeared to increase risk of oxidative stress, oxidative DNA damage and CKD; ORs and 95% CIs were 2.64 (1.44, 4.82) and 2.18 (1.22, 3.89), respectively, after adjusting for CKD and other co-variables. Our study revealed that elevated cadmium exposure induces increased oxidative stress and oxidative DNA damage concomitant with CKD in these populations of environmentally contaminated area, might be increased in morbidity and mortality of all degenerative diseases in the future.
