Introduction: Cadmium (Cd) is an industrial pollutant that affects the male reproductive system. The purpose of present study was to investigate the protective role of Beta carotene on cadmium induced testicular damage. Materials and Methods: The present study was conducted following approval from Institutional Bioethical Committee and strict internationally accepted guidelines, for the usage of animals in experimental study were. Rats were divided into four groups with 8 rats in each.The Gr. I rats were administered with the single dose of normal saline intraperitoneally. Group II received Beta carotene (10 mg/kg bw) orally for 30 days. Group III received a single dose of 1 mg/kg bw cadmium chloride and Group IV received Beta carotene for 30 days prior to cadmium administration. After the desired protocol, rats were sacrificed and both the testes were removed for biochemical and histopathological evaluation. One testis was fixed in Bouvins fluid and processed or histopathological studies. The levels of lipid peroxides (LPO) and glutathione (GSH) and superoxide dismutase (SOD) were detected in the tissue homogenates of other testis. Results: In the present study, the level of lipid peroxidation (LPO) was significantly high and GSH and SOD (P\<0.001) were low in cadmium treated rats compared to normal control. Pre-treatment with beta carotene showed a protective effect by decreasing LPO and increasing GS Hand SOD level (P\<0.001). The morphological changes like atrophy of tubules, edema and decreased spermatogenesis in the testis of rats exposed to cadmium chloride. But, antioxidant showed the normal architecture of the testis. Conclusion: Results of the present study showed the antioxidative role of beta carotene in protecting the testis from cadmium induced toxicity.

Objectives: A free radical is a molecular species characterized by the presence of an unpaired electron in its outer orbital. Free radicals are highly reactive and are known to damage biomolecules including lipids resulting in a myriad of pathophysiological conditions. The present investigation was carried out to screen antiradical and lipid peroxidation inhibitory activity of ripe and unripe fruit of R. steudneri. Methods: The powdered ripe and unripe fruit materials were extracted by maceration process using methanol. Antiradical activity of extracts was evaluated by DPPH and hydroxyl radical scavenging assays. Lipid peroxidation inhibition assay was carried out by estimating the thiobarbituric acid reactive substances. Both ripe and unripe fruit extracts were screened for the presence of phytochemicals viz. alkaloids, flavonoids, tannins, phenolic compounds, saponins, glycosides, sterols and triterpenoids by standard tests. Results: Preliminary phytochemical analysis indicated that both ripe and unripe fruit extracts contain saponins, alkaloids, phenolic compounds, flavonoids, tannins, sterols and triterpenoids. When compared to unripe fruit extract, ripe fruit extract displayed marked scavenging of DPPH and hydroxyl radicals and inhibition of lipid peroxidation as indicated by lower IC50 values. Conclusion: Overall, ripe fruit extract displayed marked free radical scavenging and lipid peroxidation inhibitory activity. The presence of phenolic and flavonoid compounds in the extracts might be responsible for observed bioactivities of ripe and unripe fruit of R. steudneri.

Objective: The current study aimed to evaluate the anti-inflammatory potency of combined curcumin and capsaicin against lipopolysaccharide (LPS) induced organ damage in mice. Methods: Adult male albino mice were distributed into five experimental groups for treatment with olive oil, LPS, curcumin, capsaicin and their combination, respectively, for 7 days prior to LPS induced inflammation. At the end of the experiment, blood samples were collected and used for the analysis of serum non-specific enzymes including serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), total bilirubin (TB), urea, creatinine and sugar, while the organ homogenates were subjected for the evaluation of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutothione S transferase (GST), nitric oxide (NO); lipid peroxidation (LPO) and it was further confirmed by histopathological study of different organs. Results and Conclusion: Curcumin, capsaicin and their combination had shown significant restoration of non-specific serum enzymes, antioxidant enzymes and attenuated inflammatory cells infiltration thereby preventing tissue/organ damage in LPS-challenged mice. However, the protective effect was found to be more when the two compounds were fed in combination. This beneficial potency of combined spice treatment is may be due to the contribution of diversified active moieties of curcumin and capsaicin in combination compared to individual molecules.

Objective: To evaluate the potential nephroprotective and antioxidant activity of hydroalcoholic Cissampelos pareira (C. pareira) whole plant extract using gentamicin-induced rats. Methods: For studying acute toxicity study, single oral dose of 2g/kg hydroalcoholic extract of C. pareira was evaluated in rats by oral gavage. The nephroprotective activity was evaluated using gentamicin-induced model in rats. In-vitro antioxidant activity was evaluated by using DPPH assay and reducing power assay. In-vivo antioxidant activity was evaluated by using glutathione and lipid peroxidation estimations in gentamicin-induced rats. Hydroalcoholic C. pareira whole plant extract was given at a dose of 200 and 400 mg/kg p.o. Results: For acute toxicity testing rats administered with the extract at a dose 2 g/ kg. the result showed no toxicity. Hydroalcoholic C. Pareira whole plant extract (200 and 400 mg/kg p.o) significantly decrease the elevated urinary glucose levels in the urine, decrease the elevated urea and creatinine levels in blood and increase the urinary creatinine levels in gentamicin-induced nephrotoxic rats. The extract had shown significant dose dependent increase in the DPPH and reducing power activity. There were a dose dependent decreasing and increasing of lipid peroxidation, glutathione levels in hydoalcoholic extract treated groups respectively. Conclusion: This study exhibits that hydroalcoholic C. pareira whole plant extract poses nephroprotective activity which may be due to its antioxidant activity.
