The main role of a seven-leaf flower

main effect

1. The antibacterial effect of Aesculus chinensis flower water infusion and decoction has an inhibitory effect on Salmonella typhi, Salmonella paratyphi A, Shiga, and Shigella flexneri in vitro. The raw water infusion has stronger antibacterial effect than the decoction.

2. Spermatozoon effect Seven-leaf flower 70% ethanol extract has sperm killing effect on rat, mouse and human sperm. Its extract is free of vaginal administration and 60% of the fertilization is inhibited by 100 mg/mouse.

3. The sedative and analgesic effects of alcohol extracts on gavage mice can reduce the spontaneous activity of mice and have a clear sedative effect. There are obvious analgesic effects by electric stimulation method and hot plate method.

4. Antiasthmatic and antitussive effect of guinea pig oral aesculus flower decoction has obvious asthma effect (group

Amine spray method). The extract (total of five species) had a significant anti-asthmatic effect when the 1/2 to 1/5 median lethal dose was given. The effect was similar to that of 1/2 half lethal dose of aminophylline. One of the extracts was saponin, and the other three Liebermsnn reactions were positive. Decoction in mice has significant antitussive effect (sulfur dioxide induced cough method), but no phlegm effect (phenol red method).

5. In the test tube (not specified), 100% of the preparations had antibacterial effects on various pathogenic bacteria such as enterobacteriaceae and pyogenic cocci in the test tube, and the use of decoctions failed to prove its antibacterial effect. The alcohol extract of 7.8 mg/ml had the effect of killing Leptospira in vitro, and water decoction at the same concentration had no effect. The quality of anti-viral drugs has an important relationship with them.

6. Toxicity, mice fed decoction 30 ~ 60 g / kg, no deaths within 3 days. The mice were administrated 0.4 g daily for three consecutive days for 3 days, or 0.2% 0.4 ml/v for intravenous injections. No deaths occurred. Therefore, the toxicity is very low.

7. Stronger antibacterial effect against influenza A virus in Asia, including dysentery bacillus, paratyphoid bacillus, salmonella, paracoccus, pseudomonas aeruginosa, staphylococcus aureus, hemolytic streptococcus, meningococcus, etc. Antibacterial effect.

8. The decoction has an antagonistic effect on "sterile inflammation" caused by dextran.

9, gavage to rats, can significantly reduce the content of adrenaline in rats vitamin C, promote adrenal function, but little effect on the thymus weight in young rats.

10, containing saponins on the isolated rabbit ear vascular smooth muscle has a direct contraction.

11. Its decoction and saponin have excitatory effects on isolated ileum of guinea pigs; both have hemolysis.


Laser Distance Meter

Laser distance measure is a very convenient tool for various types of applications in industries, construction and house decoration. Laser distance meter is a very useful device which gives accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, infrastructures, gardens, roads, and many other applications requiring accurate results for distance , area and volume measurement.

Trade your heavy tape measure for laser rangefinder, which let you simply take measurements with one hand. No matter your job, the laser rangefinder will help you measure much farther, with greater accuracy and in more situations, saving you money and time.
