Abstract

A research on Jinyulian Oral Solution was conducted and the objectives were to discover its possible acute toxicity and antibacterial effects when used in vitro and in vivo. Regarding the acute toxicity test, Kunming mice were fed a maximum amount of the solution as their stomachs could hold, i.e., 40 mL kg−1. To ascertain the minimum inhibitory concentration (MIC) of the solution, two types of germs, i.e., Staphylococcus aureus and Escherichia coli, were selected and tube dilution method was adopted. An antibacterial experimental model relying on animals’ body was developed for the researchers to observe the solution’s antibacterial effects. Test results showed that no abnormalities were discovered within 14 days after the initial date of testing and the mice grew as normal when fed with an amount of the solution 250 times of a normal clinical doze (In this case a man was assumed to weigh 60 kg.) and that the solution demonstrated obvious antibacterial effects on the two types of selected germs. The respective measured MIC50 and MIC90 values of the two germs were 3.2, 12.8, 6.4, and 25.6 mg L−1. Therefore, it is reasonable to conclude that Jinyulian Oral Solution possesses no acute toxicity but obvious antibacterial effects on the two before-mentioned germs.

Highlights

Jinyulian Oral Solution, a decoction made of herba houttuyniae, fructus forsythia, radix isatidis, Honeysuckle, and liquorice, etc. [4], has been prescribed by Suizhou Central Hospital for patients suffered from acute or chronic pharyngitis, and tonsillitis [2] for years
Two bacterial strains coded ATCC 25923 and 25922 containing S. aureus and E. coli, which were acquired from the clinical laboratory of Tongji Hospital, were regarded as the representative strains to assess the antibacterial activity of the solution
Twelve Kunming mice were classified into four groups at random, with three mice in each group

Jinyulian Oral Solution, a decoction made of herba houttuyniae, fructus forsythia, radix isatidis, Honeysuckle, and liquorice, etc. [4], has been prescribed by Suizhou Central Hospital for patients suffered from acute or chronic pharyngitis, and tonsillitis [2] for years. Medicines used include Jinyulian Oral Solution (manufactured by the Solution Production Center of Suizhou Central Hospital; Certified Number: 070308; Specification: 10 mL per bottle) and Gentamicin sulfate injection (manufactured by Hubei Tianyao Pharmaceutical Limited; Certified Number: 20060502; Specification: 80,000 U mL-1). Two bacterial strains coded ATCC 25923 and 25922 containing S. aureus and E. coli, which were acquired from the clinical laboratory of Tongji Hospital, were regarded as the representative strains to assess the antibacterial activity of the solution
