Background: Since use of synthetic drugs for relief of pain has many side effects, today medical plants are becoming more prominent as substitute therapeutic agents. Previous findings indicate that Coriandrum sativum (CS) modulates pain in both animal and human. Objective: The present work investigated the effects of CS seed on acute pain using hot plate and tail flick models.Method: Albino mice (25-30 g) were used for this study. Aqueous extract of CS seed was injected in doses of 100 and 200 mg/kg 30 min before test. The analgesic effect of the drug on acute pain was evaluated using Hot plate and Tail flick models.Results: Results indicated that CS has analgesic effect in both doses in both models and higher dose of the drug was more effective (p<0.01).Conclusion: The findings above showed that CS could modulate acute pain. Further research is required to determine the mechanisms by which CS has an inhibitory effect on pain sensation.

Background and objectives: Degradation in rumen often results in wastage of dietary proteins, particularly in productive ruminants. For this purpose, protection of proteins is essential for productive animals, where the protein requirement of these animals cannot be met from microbial protein synthesis. Therefore, this study was conducted to investigate the effect of green tea waste extract on ruminal degradability and intestinal digestibility of soybean meal dry matter and crude protein. Materials and methods: For extraction from green tea waste, a solvent was prepared with a ratio of 10 ml of methanol, 10 ml of ethanol and 80 ml of distilled water per 100 ml. The soybean meal treated at 0 (control), 5, 10, 15 and 20 percent of dry matter with this extract. Ruminal degradability of dry matter and crude protein determined using two Taleshi bulls by nylon bag method in 0, 2, 4, 6, 8, 12, 24 and 48 hours. Intestinal digestibility measured In vitro. Results: Treatment decreased the amount of dry matter (DM) degradability of soybean meal in all incubation times (P<0. 05). Crude protein (CP) degradability of processing treatments by 5% and 10% extract were not different significantly in comparison to control group (P>0. 05) but 15% and 20% extract significantly reduced CP degradability related to control (P<0. 05). Rapidly degraded fraction (a) of DM degradability of soybean meal in treatments processing with 15% and 20% extract, significantly decreased related to control (P < 0. 05). Fraction of CP degradability significantly reduced by processing in all treated group related to control (P<0. 05). Slowly degraded fraction (b) and potential degradability (a+b) of DM in 5%, 10%, 15% and 20% extract treatments significantly decreased related to control (P<0. 05). b fraction of CP degradability in control, 5% and 10% extract treatments had no significant difference, but 15% and 20% level of extract significantly decreased this fraction related to control (P<0. 05). Constant rate of degradability of DM and CP were not different between treatments. Effective degradability of DM and CP (in 2%, 5% and 8% out flow rates) significantly reduced by treatment (P<0. 05). Intestinal digestibility of DM was significantly higher in soybean meal treated with 5 and 10% extract than other treatments, but 20% extract significantly reduced it (P<0. 05). In addition, intestinal digestibility of CP was significantly higher in soybean meal treated with 5% and 10% extract than other treatments, but 20% extract significantly reduced it (P<0. 05). Conclusion: Soybean meal treatment by green tea waste extract can decrease its ruminal degradability. According to results from DM and CP intestinal digestibility, 5% and 10% levels of green tea waste extract improved soybean meal intestinal absorption and can use for protein protection against ruminal degradability.

Iced tea is a world popular beverage,for example about 80% of people in Italy and United States, consume iced tea as a thirsty-quenching beverage. However, it is also believed that iced tea contains health benefit components. Process of iced tea involved tea solid extraction and then mixing with edible acids, flavors, sugar or non-nutritional sweeteners. In this research, regarding to the demand market for new beverage, the possibility of production iced tea beverage using green tea leave was investigated and was extracted under predetermined conditions. The effects of extraction temperature and time on the extractability were examined. The results of extraction at various temperatures in sample demonstrated that the extracted solid yield increased steeply during the first 5-10 min of extraction, but gradually in next 10-30 min and after 30 min the extraction continued slowly. Tea cream and haze extract was also determined using gravimetry and spectrophotometric methods, respectively. The extraction components, which cause tea cream and haze formation in extract increased with increasing of temperature. A sharp increase was observed when extraction temperature increased from 50 to 60oC. There was no significant difference (p<0.01) between treatment regarding tea cream and haze formation between temperatures 40 and 50oC, but above 50oC was different significantly. Haze was significantly correlated to the tea cream in each extract. The linear regression coefficient for green tea leave extract was R2=0.969 (p<0.01). Iced tea beverage was flavored with different essential oil and then that acceptability was evaluated by sensory panel analyzed with multiple comparison method. A standard physical and chemical experiment, haze changes for beverage during storing was monitored for 2 months. The results indicated that produced iced tea beverage (p<0.01) was stable.

Nowadays water pollution is one of the most important problems in different societies. This problem increases with the development of countries. Existence of various dyes in waters is one of these important pollutions so adsorption can be used as an important method to eliminate dyes from waters. In this research, the adsorption of Malachite Green on odorant Do Ghazal tea waste was studied. The study of this issue was performed in laboratory’ s temperature, with variation of different parameters like pH, adsorption time, amount of adsorbent and dye concentration. The results of the experiments show that the adsorption efficiency increases with more adsorbent addition, higher pH levels and time enhancement. Also the reduction of dye concentration causes better adsorption efficiencies. Moreover the study on isotherms of adsorption process confirmed that the adsorption obeys the Freundlich model. The results of this study show that the efficiency of Malachite Green elimination in aqueous solutions on odorant Do Ghazal tea waste was higher than 95%. An artificial neural networks (ANN) model was developed to predict the performance of the decolorization efficiency by the adsorption process based on the experimental data. A comparison between the predicted results of the designed ANN model and experimental data was also conducted. The ANN model yielded a determination coefficient of R2=0. 9981. The model can describe the decolorization efficiency under different conditions. Odorant Do Ghazal tea can be used as a low cost and available adsorbent to removal of organic pollutants from contaminated waters. Artificial neural networks can be employed as an appropriate method for adsorption process modeling too.

This study was conducted to investigate the effects of different levels of green tea waste (GTW) on gain performance, nutrient digestibility and nitrogen balance in feedlot lambs. For this purpose, four experimental treatments with 0, 2, 4 and 6 percent of dry matter GTW were used. The amount of final body weight, daily weight gain and feed conversion ratio were significant among treatments with 2, 4 and 6% GTW (P<0. 05) but there was no significant difference between treatment with 2% GTW and control in relation to performance. Treatment contain 2% GTW had the highest value of CP digestibility among the treatments (P<0. 05). There were no significant differences in DM and OM digestibility of 2% GTW treatment and control group, but they were significantly more than other treatments (P<0. 05). Nitrogen retention of 2% GTW treatment was not significantly different from control treatment, but it was significantly more than other treatments (P< 0. 05). The amount of ammonia nitrogen of rumen liquor was significantly lesser in GTW treatments than control (P<0. 05). The concentration of blood urea nitrogen was significantly lesser in GTW treatments than control (P<0. 05). According to the results, using GTW in 2% level (DM) of lamb’ s feedlot diet improved performance because of better digestibility and nitrogen balance.
