  This study evaluates the chemopreventive effect of an aqueous extract of fresh leaves of Azadarichta indica against liver cancer. Twenty male rats (Spraque dawley), 150-250 g, were acclimatized for 1 week before use. The rats were divided randomly into 4 groups; cancer control group (C), cancer treated with 5% Azadarichta indica extract group (CAI), normal control group (N) and normal treated with 5% Azadarichta indica extract group (NAI) and each group contains 5 rats. Rats in group C and CAI were induced cancer by intraperitoneal injection of 200 mg kg-1 diethyl nitrosamine (DEN) as hepatocarcinogenesis initiator and then followed by 2-acetylaminofluorene as promoter of hepatocarcinogenesis (0.02% in food) for 2 weeks. The rats were then left for 2 weeks. The rats in group N and NAI were injected once intraperitoneally with corn oil and act as control. The plant was fed orally to CAI and NAI groups. Serum concentration of alpha-fetoprotein (AFP) as liver tumor marker was measured. Glutathione S-transferase (GST) and glutathione peroxidase (GPx) were measured in the serum and liver cytosol. The results of this study revealed that there is a significant difference (p≤0.05) between C and CAI groups in serum alpha-fetoprotein and, in serum and liver cytosol levels of glutathione S-transferase and glutathione peroxidase. While there was no significant difference (p0.05) between NAI and N group in GST and GPx level. As a conclusion from this study that the consumption of 5% of NEEM leaves aqueous extract resulted in complete inhibition of chemically induced hepatocarcinogenesis in Spraque dawley rats.

  The aim of the present study was to investigate the effect of Strobilanthes crispus juice on glucose, lipid profile, glutathione peroxidase and superoxide dismutase in normal and streptozotocin-induced diabetic male and female albino Sprague-Dawley rats. This study was conducted on normal and streptozotocin-induced diabetic male and female Sprague-Dawley rats fed with basal diet and S. crispus juice with different doses 1.0, 1.5 and 2.0 mL k-1 b.wt. for 30 days. The results showed that significant (p<0.05) decrease in serum glucose levels in male and female diabetic and normal rats with treated S. crispus juice (1.0, 1.5 and 2.0 mL k-1 b.wt.). Cholesterol and triglyceride level significantly (p<0.05) decreased in diabetic rats treated with 1.0, 1.5 and 2.0 mL k-1 b.wt. of S. crispus juice. Cholesterol, triglyceride and LDL-cholesterol level showed reduction in treated male and female normal rats. HDL-cholesterol showed the increasing but not significant (p<0.05) difference in treated diabetic and normal male and female rats. Glutathione peroxidase and superoxide dismutase activities significantly (p<0.05) increased in treated diabetic and normal male and female rats. In conclusion, S. crispus juice possesses antihyperglycemic, hypolipidemic and antioxidant effect in streptozotocin-induced diabetic rats. Thus, S. crispus juice could be the alternative treatment for lowering glucose, cholesterol and triglyceride for diabetic patients in the future.

  Conjugated Linoleic Acids (CLAs) are group of positional and geometric isomers of octadecadienoic acid with conjugated double bonds and believed to have many health promoting effects. The present study focused on the quantitative analysis of CLAs in liver, Superficial Pectoral (SP), Longissimus Dorsi (LD) and Semimembranosus (SM) muscles of local Malaysian Kedah-Kelantan (KK) cattle slaughtered for human consumption. Fatty acids were extracted using Folch method and determined by gas chromatography. The average content of CLAs in the liver, SP, LD and SM muscles were 38.71, 18.24, 11.03 and 13.04 mg/100 g of sample, respectively. The quantity of CLAs in the liver was significantly (p<0.05) higher than other samples. The percentages of cis-9, trans-11 CLA isomer were 63.39, 76.04, 90.66 and 82.82% of total CLAs in the liver, SP, LD and SM muscles, respectively. Positive correlations between CLAs and trans-11-octadecenoic acid concentration were observed in all samples. This study confirmed that meat from KK cattle could be the potential source of CLA but still its content has to be improved to make their meat more beneficial for consumers.

  This study was focused on the quantitative analysis of Conjugated Linoleic Acids (CLAs) in rumen liquor and assessment of the relationship between CLAs and other carbon 18 fatty acids and rumen pH of cattle slaughtered for meat consumption. The fatty acids were extracted using modified Folch method and determined by gas chromatography. The mean (n = 22) level of CLAs in the rumen liquor was 14.97 ±7.46 mg/100 mL. Cis-9, trans-11(c9, t11) was the dominant isomer of CLA followed by trans-10,cis-12 (t10, c12). The level of CLAs was positively correlated with the concentration of octadecatrienoic (18:3), cis-9, cis-12 octadecadienoic (18:2), trans-11octadecenoic (18:1) and octadecenoic (18:0) acids. Ruminal pH was positively correlated with the amount of c9, t11 and total CLA and negatively correlated with t10, c12 CLA isomer. All these correlations and relationships indicated that CLAs production in the rumen is dependent on availability of carbon 18 fatty acids and pH of the rumen liquor.

  The objective of this study is to determine the effect of Strobilanthes crispus Juice (SCJ) on wound healing and antioxidative enzymes activity in normal and streptozotocin-induced rats. A total of 48 male albino Sprague dawley rats, weight 150-200 g were used. The rats were divided into 8 groups with 6 rats in each group. The healing of 2 cm linear incisions created on the back of each rat was monitored by measuring the length of the wounds daily. The result showed a significant increase (p<0.05) in the percentage of wound healing at day 3 and 7 in the treated group especially treated with 140 mg kg-1 b.wt. of S. crispus juice in diabetic and normal rats compared with the control. Strobilanthes crispus juice increased significantly (p<0.05) of glutathione peroxidase (GPx) and superoxide dismutase (SOD) activity in treated group in diabetic rats. Significant correlation was found between wound healing, GPx and SOD enzymes. In conclusion, S. crispus juice enhanced wound healing in normal and diabetic rats.

  The effect of 5% w/v of Strobilanthes crispus (SC) extract and glycyrrhizin in diethylnitrosamine and acetylaminofluorene induced hepatocellular carcinoma, which is a vital mechanism in cancer treatment, was studied in male Sprague-Dawley rats. The obtained results have shown a significant, increase (p<0.05) of liver microsome Aniline Hydroxylase (AH) in cancer group rats after 12 weeks. Treatment with glycyrrhizin caused decrease in liver AH activity compared to control. Meanwhile, treatment with SC caused overall decrease in liver AH activity almost near to control groups. Meanwhile, microscopic observation of the lesion score during hepatocarcinogenesis revealed that cells of cancer group without treatment were severely necrotic at week 12. However, S. crispus treatment was reduced the severity in cancer group rats at week 12. The result also indicate that SC only ameliorated the cancer incidence in the liver, however did not fully recover the liver tumor similar to the normal cells. This might be due to short experimental duration.
