Atherosclerosis in cardiovascular disease (CVD) is a growing health problem, especially in developing countries. Hyperlipidemia is known as a dominant risk factor for the development of atherosclerosis. This study was designed to investigate the effects of Eurycoma Longifolia (EL) also known as Malaysian Ginseng/ Tongkat Ali on the testosterone level, biochemical changes of lipid profile and intima media thickness (IMT) in rats fed on high-fat diet. Twenty young, adult male Sprague-Dawley (SD) rats were housed for 12 weeks. After one week of acclimatization, they were randomly divided into four groups of 5 animals each and treated for 12 weeks as follow: Group ND was given only normal diet, group NDEL was given normal diet and EL extracts (15mg/kg) dissolved in distilled water, group HFD was given only high fat diet and group HFDEL was given high fat diet and EL extracts (15mg/kg). Rats which were treated with EL (NDEL and HFDEL) showed a significant increase (p<0.05) in the testosterone levels. There was a significant decrease (p<0.05) in triglyceride (TG) in HFDEL group compered to HFD group. The histological sections of aortas revealed a significant decrease (p<0.05) in IMT in HFDEL as compared with HFD group. No histological changes were observed in NDEL group compared with ND group and there was no significant difference in IMT values between NDEL and ND. These findings suggest that EL is a promising protective agent against atherosclerosis induced by high-fat diet.

Background/Aims: Although peritoneal tuberculosis (TB) is one of the important differential diagnoses among cirrhotic patients with ascites, a peritoneal biopsy is not always available. High ascitic fluid adenosine deaminase (ADA) has been indicative of peritoneal TB. On the other hand, studies to assess its diagnostic utility based on the confirmation of peritoneal biopsy in cirrhotic patients are scarce. Methods: Patients with new-onset ascites were enrolled prospectively from a tertiary hospital. Peritoneal biopsy was applied according to clinical judgment when required. Based on pathology diagnosis of the peritoneum, the diagnostic efficacy of ascitic fluid ADA for peritoneal TB was evaluated in total and cirrhotic patients, respectively. Results: Among 286 patients enrolled, 78 were diagnosed with peritoneal TB. One hundred and thirty-two patients had cirrhosis, and 30 of those were diagnosed with peritoneal TB. The mean ADA was 72.2 U/L and 22.7 U/L in the peritoneal and non-peritoneal TB group, respectively, among the total study population, and 64.0 U/L and 19.1 U/L in the peritoneal and non-peritoneal TB group, respectively, among the subgroup with cirrhosis. The area under the curve for ADA to diagnose peritoneal TB was 0.96 in the total study population with a cutoff value of 41.1 U/L, and 0.93 in cirrhotic patients with a cutoff value of 39.9 U/L. Conclusions The ascitic fluid ADA measurements showed high diagnostic performance for peritoneal tuberculosis in patients with ascites regardless of cirrhosis at a similar cutoff value.

OBJECTIVE: Prolonged use of nonsteroidal anti-inflammatory drugs is associated with severe side effects and toxicity. Therefore, we studied the anti-inflammatory role of Calcarea carbonica which had minimal toxicity at the low doses. METHODS: THP-1 human mononuclear cells were treated with C. carbonica to evaluate the 50% cytotoxicity concentration (CC) and 50% effective concentration (EC). Cell survival was evaluated in lipopolysaccharide-stimulated C. carbonica-treated cells. Nitric oxide (NO) and tumor necrosis factor-α (TNF-α) were measured to evaluate the anti-inflammatory activity of C. carbonica. Cyclooxygenase-2 (COX-2) protein expression was determined by Western blotting analysis, and the interaction of C. carbonica with the COX-2 protein was evaluated using molecular docking simulation. RESULTS: The CC and EC of C. carbonica were found to be 43.26 and 11.99 µg/mL, respectively. The cell survival assay showed a 1.192-fold (P = 0.0129), 1.443-fold (P = 0.0009) and 1.605-fold (P = 0.0004) increase in cell survival at 24, 48 and 72 h after initiating C. carbonica treatment, respectively. C. carbonica-treated cells showed a reduction in NO levels by 2.355 folds (P = 0.0001), 2.181 folds (P = 0.0001) and 2.071 folds (P = 0.0001) at 24, 48 and 72 h, respectively. The treated cells also showed a reduction in TNF-α levels by 1.395 folds (P = 0.0013), 1.541 folds (P = 0.0005) and 1.550 folds (P = 0.0005) at 24, 48 and 72 h, respectively. In addition, a 1.193-fold reduction (P = 0.0126) in COX-2 protein expression was found in C. carbonica-treated cells. The molecular docking showed interaction of C. carbonica with the phenylalanine 367 residue present in active site of Cox-2. CONCLUSION C. carbonica exhibited anti-inflammatory properties in lipopolysaccharide-stimulated cells by significantly reducing NO production and TNF-α level through downregulation of the COX-2 protein. This effect is probably mediated through interaction of C. carbonica with the phenylalanine 367 residue present in active site of Cox-2.
