Red betel leaf (Piper crocatum) contains useful chemical compounds like alkaloid, saponin, tannin, and flavonoid which have an anti-inflammatory and antibacterial characteristics. Previous research shows red betel leaf has a better bactericidal profile than the green ones. The red betel leaf extract is already proven to disturbing the growth of periodontal causative bacteria in an earlier study. Any ingredient or chemical contents on food and drug shall run a toxicity test before permitted to use generally. This study’s purpose is to investigate the acute toxicity effect of red betel leaf extract as a periodontal pocket therapy ingredient. The acute toxicity experimental is conducted on Swiss webster mice which divided into six groups consisting of 4 males and four females each. The dose given to the subject is a single dose by the oral route as amount as the twice maximal tolerated dose that is 10000, 5000, 2500, 1250, and 625 mg/kg BW. The weight of mice is measured every day from day-1 until day-14 after that (on day-15) the mice are cut to counting relative organ index. The collected data is analyzed using The One-way ANOVA test and continues with the posthoc Tucay test. This study result shows that red betel leaf extract with doses 10000, 5000, 2500, 1250, and 625 mg/kg BW given acutely doesn’t generate a significant change in weight and relative organ index of the test’s subject. Based on this result, it can be concluded that red betel leaf extract is not toxic.

This study was designed to ascertain the safety profile as well as explore new antimicrobial agents from the methanol leaf extract of Stachytarpheta indica. The methanol extract was prepared and screened for its phytochemical composition, oral acute toxicity profile as well as challenged with common pathogenic microorganisms for its antimicrobial activities using standard procedures. The phytochemical analysis revealed the presence of various pharmaceutically active secondary metabolites like alkaloids, saponins, carbohydrate, cardiac glycosides, terpenoid, tannin, anthraquinones, phenolics and flavonoid. P. aeruginosa and S. aureus showed the best and least antibacterial activity respectively. The extract exhibited antifungal activity in a dose dependent manner with the inhibition more pronounced with A. niger than with C. albicans. The standard drugs ciprofloxacin and fluconazole exhibited a near 100% activity. There was no mortality at 8 g/kg p.o. after 24 hours and no sign of delayed toxicity or mortality after 14 days of observation. There were no statistically significant differences (p > 0.05) observed in the examined organs as well as body weights in both 24 h and 14 d study. This research holds promise for the exploration of various potentially active secondary metabolites which would help in developing pharmaceuticals especially antimicrobial drugs as well as recommend the short-term oral administration of the extract up to a dose of 8 g/kg body weight.

: The aim of the present study was to develop quantitative structure-activity relationship (QSAR) models, based on molecular descriptors to predict the oral acute toxicity (LD50) of organophosphate compounds. The QSAR models based on genetic algorithm-multiple linear regression (GA-MLR) and back-propagation artificial neural network (BP-ANN) methods were proposed. The prediction experiment showed that the BP-ANN method was a reliable model for screening molecular descriptors, and molecular descriptors obtained by BP-ANN models could well characterize the molecular structure of each compound. It was indicated that among molecular descriptors to predict the LD50 (mgkg-1) of organophosphates, ALOGP2, RDF030u, RDF065p and GATS5m descriptors have more importance than the other descriptors. Also BP-ANN approach with the values of root mean square error (RMSE= 0.00168), square correlation coefficient (R2= 0.9999) and absolute average deviation (AAD=0.6981631) gave the best outcome, and the model predictions were in good agreement with experimental data. The proposed model may be useful for predicting LD50 (mgkg-1) of new compounds of similar class.

This article use the Sulphide Isobutene (T321), Five Sufides Dialkyl(RC2540) and Star of Phosphorus(P110) as the additives,Neopentyl Polyol Ester(NPE) and mineral oil N32 as base oil. Compound above additives and base oil for the four levels. A sample: adding 4% T321 additive in NPE. B sample: adding 4% T321 additive in N32. C sample: adding 4% RC2540 additive in NPE. D sample: adding RC2540, T321 and P110 additives in NPE (all is mass fraction). The oral acute toxicity test, eye mucous stimulation test, skin hypersensitive test, soaking tail toxicity tests were conducted in above samples. The test results show that. The mineral oil, it’s not only toxic then synthetic oil but also has a poor lubricating ability compare with the same percent additive in synthetic oil. In oral acute toxicity test, eye mucous stimulation test, skin hypersensitive test, soaking tail toxicity tests, Toxic reaction of mineral N32+4%wt Sulphide Isobutene (T321) obviously from other oil samples.
