Malaria still becomes a global health problem due to its high morbidity
and mortality, mostly in tropic countries. Artemisinin, the active
compound produced by Artemisia annua L., is a promising drug to treat
malaria, especially which caused by the resistant of Plaslnodiurn falciparUm against chloroquin. There are obstacles in production of arternisinin supplies because its synthesis needed a large manu facturing cost and complicated to accomplish. The artemisinin content in plants is very low and varies, so that in vitro culture technique is expected to be an alternate production of artemisinin. Nutrients in growth medium could influence the content of active compounds produced. One of the nutrients is gibberelin acid (GA3). It could influence the synthesis of sesquiterpene lactone, including artemisinin. Therefore the in vitro culture experiment of A. annua with adding GA3 is needed to develop in order to increase the content of artemisinin. Complete Randomized Design (CRD) was applied to this study with GA3 concentration used were 0; 0,01; 0,1 and 1 mg/L. Sterilized explants from A. annua were grown on liquid Murshige Skoog (MS) medium for 30 days, then subcultured on agar MS which contained GA3 with various concentration. The result showed that the concentrations of GA3 applied on this study (ie: 0,01; 0,1 and 1 mg/L) could decreased wet and dry weight of A. annua shoot, although the artemisinin content was not influenced significantly by the adding of GA3.

Increased prevalence of methicillin-resistant Staphylococcus aureus
(MRSA) has become a major threat to the health sector worldwide due
to their virulence, limited therapeutic options and their distribution in
both hospital and community settings. Discovery and development of
Isa, Shuhaimi Mustafa, new anti-MRSA agents as alternatives to the very few antibiotics left in
the armamentarium are thus, urgently required. Recently, an efflux
Dayang Fredalina Basri mechanism in MRSA has been identified as one of the main contributors
of resistance towards various structurally unrelated antibiotics. The potential of reserpine (a phytoalkaloid) as efflux pump inhibitor (EPI) against various microbes remains limited as the concentration needed for inhibition is toxic to humans. This study therefore aimed to evaluate 13 alkaloid compounds as potential inhibitory against and/or potential EPIs against a panel of three MRSA isolates which not only differ in their susceptibility to vancomycin (amongst the last drugs available to treat serious MRSA infection), but also exhibit active efflux activity. Results indicated berberine’s moderate inhibitory activity against two MRSA isolates scoring a minimum inhibitory concentration (MIC) value of 125 µg/ml. Notable efflux inhibitory activity (ranging from two to eighrfold Ethidium Bromide MIC reduction) meanwhile was detected from quinine, piperine and harmaline using reserpine as the positive control. Findings from this study support the opinion that a vast number of potential phytocompounds with pharmacological potential await discovery. Therapeutic application of these compounds, however, warrants further investigation to ascertain their pharmacodynamics and safety aspects.

The results showed that at all three monitored time points, 8, 6 and 20 weeks following streptozotocin injection, hypoglycemic activity of garlic extract was 74.22, 96.23 and 93.27 percent of activity of tolbutamide, respectively. Concomitantly, the levels of serum insulin were increased up to 37.03, 42.16 and 62.66 percent of tolbutamide effect. Besides, the levels of serum cholesterol and triglycerides in STZ-G rats were lower, whereas the levels of serum HDL were higher than those of STZ-rats. Moreover, garlic has been shown to attenuate the abnormalities of cardiac functions. Systemic blood pressure was significantly decreased, while heart rate, aortic flow rate and coronary flow rate were greater than those of STZ-rats. Left ventricular isotonic contraction values of STZ-rats were higher than those of STZ-rats at 16 and 20 weeks following streptozotocin injection. However garlic extract could not significantly reduced proteinuria at all three monitored time points. Examination of vascular morphology by scanning and transmission electron microscopes demonstrated that the inner surface of coronary artery and arteriole of STZG rats were smoother than those of STZ-rats. Moreover, the thickness of arterial wall and capillary basement membrane of STZ-G rats were thinner than those of STZ-rats. The results of this study implied that garlic could be a useful agent for preventing or delaying the diabetic cardiovascular complications
The objective of this study was to investigate the hypoglycemic activity

extract. The chemical compound screening showed phenolic compounds .Benth., insulin,
and flavonoids, which were found 13.07±7.5 mg/g and 1.73±0.14 μg/g,
respectively. In oral glucose tolerance, the extract at 0.2 and 0.5 g/kg
showed a little hypoglycemic effect in normal rats. The extract at 1.0
g/kg was the most effective and response was closed to the result of glibenclamide. In streptozotocin-diabetic rats, the extract at 0.5 and 1.0 g/kg significantly reduce plasma glucose. After repeated daily oral administration of the extract or glibenclamide for 14 days, glibenclamide significantly decreased plasma glucose in diabetic rats at day 8 but not the extract. However, after 14 days, both the extract and glibenclamide significantly reduced the plasma glucose. The blood chemical values were not significantly different from control, except aspartate aminotransferase (AST) and high-density lipolipid (HDL). Histopathological findings showed no evidence of lesions related to the extract toxicity. The extract (100 μg/ml) in the presence of high glucose stimulated insulin release about 11 times over the baseline from perfused rat pancrease. The results of this study demonstrated that the extract exerted the hypoglycemic effect in diabetic rats and stimulated insulin release in the presence of high glucose. Therefore, the extract should be useful in the treatment of diabetics

effect using the oral glucose tolerance test (OGTT) in comparison with
Ruangsomboon, O and tolbutamide in normal rats. The plasma glucose levels in rats given the
Temsiririrkkul Rungravi alcoholic extracts at the doses of 1 and 2 g/kg body weight were
significantly lower than those of control group (P>0.05), but fresh leaves at the same doses did not show this effect. At 2.5 hours after feeding, the alcoholic extract at a dose of 2 g/kg body weight could lower the plasma glucose level about half of the hypoglycemic effect of tolbutamide at a dose of 0.5 g/kg body weight,i.e.,22.9% and 46% lower than those of the control value, respectively
