Promoting Effect

This study aimed to investigate the antitumor-promoting effects of total ethanolic extract from Perilla leaf (PLE) in a two-stage chemical carcinogenesis protocol in mice. Quantitative analysis active compounds in PLE were performed by thin layer chromatography with normal phase of silica gel F254 and HPLC-PDA with reversed phase of C18 column at UV 300 nm. The cutaneous tumors were initiated by a single application by 7,12-dimethylbenz[a]anthracene (DMBA) on the dorsal shaved skin, then promoted by repeated applications of croton oil during 20 weeks. PLE was topically applied daily until the end of the experiment. The results observed from thin layer chromatogram highlighted the presence of rosmarinic acid and luteolin in PLE. By means of HPLC-PDA analysis, the total content of rosmarinic acid and luteolin were found in amounts of 1.178 ± 0.011 % (w/w) and 0.105 ± 0.001 % (w/w), respectively. The PLE-treated group prolonged the latency period of tumor appearance up to 2 weeks and also significantly reduced tumor volume in dorsal skin of mice as compared to untreated group. In conclusion, the total ethanolic extract from leaves of Perilla frutescens demonstrated promising antitumor-promotion activity in mouse skin.

Investigations on the hydrophobic and ionophoric character of para-(5-phthalhydrazide-azo)-phenylene-N-aza-15-crown- (1) were carried out by reversed phase thin layer chromatography (RP-TLC) and spectrophotometric measurements. The study included complexes with Li+ and Na+ cations (as perchlorates in acetonitrile and as dibenzyldithiocarbamate salts in chloroform). In both cases, the stoichiometry of complexes was 1:1:1 (1:M+:anion pair). The complex stability (logKS ) is similar.

<p>ABSTRACT<br />Objective: The goal of the present study was to examine the viability of Morus alba (M. alba) ethanolic extract in repression of obesity-associated<br />hepatic steatosis and related metabolic disorder; dyslipidemia, hyperinsulinemia, and glycemic status.<br />Methods: Adult female albino rats were randomly assigned into four groups, eight rats each as follows: Group (1) control group received standard<br />rodent diet for 24 weeks. The other three groups administered high cholesterol diet for 12 weeks and served as obese group, M. alba-treated group,<br />and simvastatin-treated group.<br />Results: The current results showed an increment in thoracic circumference (TCX) and abdominal circumferences (AC) as well as body mass index<br />(BMI) in obese group. In addition, dyslipidemia, hyperinsulinemia, hyperglycemia, and insulin resistance have been elucidated in obese group.<br />Moreover, hepatic malondialdehyde (MDA), nitric oxide (NO), serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and bilirubin<br />values were significantly increased in obese groups versus control group. On the other hand, administration of ethanolic extract of Morus alba or<br />simvastatin could significantly lessen BMI and in addition to improve dyslipidemia in obese group. Glucose, insulin levels, and insulin resistance value<br />in serum samples demonstrated a significant reduction in obese group upon treatment with M. alba ethanolic extract or simvastatin. Furthermore,<br />noticeable depletion in hepatic MDA, NO contents, serum ALT, AST activities, and serum bilirubin level was recorded as a result of treatment with<br />either ethanolic extract of M. alba or simvastatin. Histopathological examination of liver tissue showed ballooning degeneration in the hepatocytes<br />(hepatic steatosis) associated with inflammatory cells penetration in portal zone in obese group. Meanwhile, the treatment of obese groups with<br />ethanolic extract of M. alba or simvastatin was found to restore the structural organization of the liver.<br />Conclusion: The present findings provide a novel aspect for understanding of the role of M. alba against obesity-associated liver diseases and related<br />metabolic disorder. The mechanisms underlying these effects seem to depend on the hypolipidemic potential, anti-inflammatory property, and<br />antioxidant activity of its phytochemicals.<br />Keywords: Obesity, Morus alba, Dyslipidemia, Hyperinsulinemia, Hyperglycemia, Hepatic steatosis.</p>

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.
