  The 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) convert inactive circulating 11-keto steroids into active glucocorticoids, amplifying local glucocorticoid action. It is elevated in adipose tissue in obese humans and rodents, suggesting that adipose tissue glucocorticoid excess may be the causative factor for obesity. This study was conducted to evaluate the effects of Piper sarmentosum (PS) water extract and glycyrrhizic acid (GCA) on 11β-HSD1 bioactivity in ovariectomized induced obese rats. Fourty-two female Sprague-Dawley rats were randomly divided into six groups; four treatments (PS, GCA, CTRL and SHM) and two basal (B-CTRL and B-SHM). All groups underwent ovariectomy excluding SHM and B-SHM which underwent sham operation. Basal groups were sacrificed on the first day of treatment, while ovariectomized groups were given PS extract (0.125 g kg-1), GCA (0.120 g kg-1) and water (CTRL), respectively, while SHM received only water. Blood pressure was measured monthly while body weight weekly. After five months, rats were sacrificed and liver, heart and visceral adipose tissues were taken for analysis. Piper sarmentosum (PS) and GCA group showed a significant reduction in enzyme activity but no difference in body weight compared to CTRL group. Meanwhile only the blood pressure in GCA group was significantly higher after three months of treatment as compared to CTRL group but no difference after five months. In conclusion, both PS water extract and GCA have the ability to reduce 11β-HSD1 enzyme activity but only GCA cause an increased in blood pressure.

  The effect of treatment with Radix™ on ethanol-induced gastric lesions was investigated. The main ingredient of Radix™ is Eurycoma longifolia. Twenty-four rats of the Sprague-Dawley species were randomly divided into four groups. Three groups were given 0.5 mL 100% ethanol orally. Another group was used as a control and was given only distilled water orally (control). After 6 h all the rats were fed with normal diet. One group that was administered with ethanol was only given distilled water orally (no treatment). Another two groups that were administered with ethanol were treated with oral Radix™ 0.128 mg g-1 b.wt. (Radix) and oral ranitidine 21.4 mg kg-1 b.wt. (Ranitidine), respectively. After one week, all the rats were fasted overnight and sacrificed. The stomach was isolated and examined for the presence and severity of gastric lesions. Measurements for malondialdehyde content and gastric acid concentration were also done. It is found that the ulcer index was lower in the Radix and ranitidine group compared to the no treatment group whereas in the control group there was no lesion. There was no difference in ulcer index between the Radix and ranitidine group. The gastric MDA content was significantly higher in all the groups that were induced with ethanol compared to the control group but no difference between all the ethanol-induced groups. There was no difference in the gastric acid concentration in all groups. Hence it is concluded that Eurycoma longifolia in Radix™ is as effective as ranitidine in the treatment of ethanol-induced gastric lesions in rats.
