Therapheutic agents from plants are believed to be effective, sustainable and readily available which stimulate researchers to explore various activities of plants. This study is aimed to investigate the activity of Gardenia jasminoides (G. jasminoidesleaves in enhancing the length of bleeding time and clotting time thus can be optimized to be a potential thrombolytic agent in the future. The animal were classified into 5 groups included 3 treatment groups receiving G. jasminoides leaves (GJL) extract at dose 100, 200, 300 mg/kg BW, 1 positive control receiving aspirin 0.208 mg/20 g and 1 negative control. Mice treated with GJL extract delayed the clot formation with the highest dose showed effects as strong as positive control.

Diabetes is defined as a chronic hyperglycemia which should be countered by the effective, safe and readily available hypoglycemic agents. Herbal is among alternatives that has been used by society for years but lacks of documented evidences. Tinospora crispa (TC) is enriched by phytochemicals which potentially reduce blood glucose thus is useful for diabetic patients. This study aimed to investigate the potency of TC inreducing blood sugar and body weight. It involved 30 healthy rats divided into 5 groups namely: normal control, normal fed with TC extract, diabetic, TC-treated diabetic (dose 500 mg/kg w/w), and vitamin E-traeted diabetic rats (60 IU). The body weight and fasting blood glucose were measured each week for 1 month. The administration of TC extract 500 mg/kg (w/w) helps to maintain body weight in diabetic rats and reduce the fasting blood glucose. TC is highly potent as hypoglycemic agents therefore needed to be explored further.

Since the publication of inventory list for dragonflies and damselflies within the boundary of Andalas University’s Limau Manis Campus Complex, Padang, on 2018, the survey efforts have been continuously conducted. Hence, in this article we add five odonate species new for Andalas University’s Limau Manis Campus Complex, with one species Drepanosticta cf. bispina may require further investigation and elaboration on its existence in West Sumatra. We also corrected the identification of Heliocypha fenestrata into H. angusta angusta. With this addition, Andalas University’s Limau Manis Campus Complex currently resides for 32 species and 9 families of Odonata, increasing from previously 27 species and 8 families.

Cellulose had been isolated from rice husk waste and sawdust with chemical method through hydrolysis with HCl 2.5 N and bleaching process with H2O23%.The yields were 13,45% and 22,75% (w/w) of cellulose from rice husk waste and sawdust, respectively. The chemical treatment caused partial removal of lignin and hemicellulose from raw material showed by FTIR spectrum. Structure and morphology of cellulose from rice husk waste and sawdust were investigated using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The XRD patterns showed cellulose structure converted from amorphous to crystalline form after bleaching process while SEM images showed that the isolated cellulose from rice husk waste had rougher surface than cellulose from sawdust. The SEM micrograph also showed that the isolated cellulose from rice husk was in the form of aggregates.

Tuberculosis is caused by the bacterium Mycobacterium tuberculosis, which by only using a few new antibiotics, can kill the bacteria. Tuberculosis treatment has several stages, namely intensive and advanced stages. Compliance with the use of OAT is an imported factor in the success of TB treatment. The use of many drugs can cause side effects that result in patients stopping treatment when it creates the TB treatment process to fail. Improved adherence can do by using a fixed-dose combination OAT. In the intensive phase, the patient will get a fixed-dose combination containing a mixture of four antibiotics. The purpose of this study is to evaluate the potential side effects that occur during fixed-dose combination OAT treatment at an intensive stage and see the level of compliance of patients taking TB drugs. Observational sampling in TB patients was taking OAT at an acute stage by looking at side effects that arise during treatment and then analyzed using statistics and algorithm Naranjo. The results showed the most common potential side effects for fixed-dose combination OAT in the intensive stage were itching, headache and nausea with a percentage of 72% each, joint pain 45%, stomach pain 36.4%, lack of appetite and rashes 27.3% each and reddish color in the urine 18.2%. The results of the analysis using Naranjo logarithm obtained results eight, which means the side effects might cause due to the use of the drug. The results of patient compliance achieved a 100% compliance rate
