Acute (oral) toxicity study in Swiss mice after 24 hours administration of non-polar methanolic extract of Selaginella bryopteris
| Group | Dose (mg/kg bw) | D/T | Period of observing sign (hours) | Obsereved toxicity |
|---|---|---|---|---|
| A | - | - | 24 | No toxicity observed |
| B | 250 | 0/5 | 24 | No toxicity observed |
| C | 500 | 0/5 | 24 | No toxicity observed |
| D | 1,000 | 0/5 | 24 | No toxicity observed |
| E | 2,000 | 0/5 | 24 | Slight dullness was observed in the first two hours |
Bw, body weight; D/T, ratio of the number of dead rats to the number of treated rats.
Period, mortality latency, time to death (in hour) after the oral administration of the extract; the number of rats in each dose group (n) was 12.
