Particular situation when using Microsoft Excel software in biological statistics (Continued)

Counting the average number and standard error or standard deviation by popular method of 3 groups also leads to correct results as using Microsoft Excel software. When using Summary Statistics in Descriptive Statistics, we have average value, standard error, standard deviation and other results, in which there was a sample variance. If 2 variances of 2 samples were the similar, t test has been used. Thus, using Microsoft Excel software, we’ll have specific p value. From that, we could infer the greater or smaller results

Particular situation when using Microsoft-Excel in biological statistics

Calculating mean number and standard error or standard deviation by normal calculation method has the correct result as using Microsoft – Excel. Applying Summary Statistics in Descriptive Statistics, we get mean number, standard error, standard deviation and many other results including Sample Variance. If two variances of two samples are the same, we use T- test method. Therefore, we have concrete value of p, which can be use to identify higher or lower expressed value

Particular situattion when using Microsoft-Excel in biological statistic

The way of counting average number and standard error or standard deviation by normal count method on all three lots showed the same results like as Microsoft - Excel. Application of Summary Statistics in Descriptive Statistics showed average value, standard error, standard deviation and many other results in which there are sample variance. If two variances of two samples are the same, T proof method is used. Like this, use of Microsoft Excel showed concrete numeric value of p

Method for determination of the effective dose ED50

There are 4 principle of determination of ED50, the dose effective on 50% of experimental animals. Animals had been distributed into various analogue for diverse doses of studied substance. The evaluation will be carried according to the principle of "yes/no". For 1st example: To determine ED50 concerning the anti-fibrillation effect of venous infective propranolol on BaCl2 included heart fibrillation experimental model of rabbit.Result showed an efficacious dose of ED50 = 1,97mg/kg. For 2nd example: to determine ED50 concerning the hypoglycemic effect of glibenclamid on alloxan included hyperglycemic experimental model on white rat. Result showed on efficacious dose of ED50 = 6,02mg/kg

Studies on extraction and in vitro anti-urolithic effect of the prescription ngu linh gia vi

Dried powder extraction: Among the components of the traditional oriental prescription “Ngu linh gia vi”, rhizoma Atractylodis macrocephalae, Polia, Polyporus, rhizoma Alismatis and cortex Cinnamomi were extracted with ethanol 80%; the others were extracted with boiled water. All the extracts were mixed with rhizoma Dioscoreae persimilis powder, then dried in vacuum. The total yield of the dried extract was 7.7% compared with the plant materials. Anti-urolithic effect: In vitro studies showed that the percentages of worn stones were respectively 0.92% (control group), 18.94% (low dose of dried extract group), and 19.97% (high dose of dried extract group).
