m- / p-CRESOL MIXTURE<br />

5. TOXICITY ID: 15831-10-4<br />

DATE: 24.05.2004<br />

Method : other: determination of sperm motility and concentration in males and<br />

length of oestrus cycle and vaginal cytology following repeated dose<br />

according EPA OPP 82-1<br />

Year : 1991<br />

GLP : yes<br />

Test substance : other TS: m-/p-cresol (60%:40% mixture)<br />

Remark : see also chapter 5.4.<br />

Result : males:<br />

no difference to the respective controls in weights of right<br />

testicle, right epididymis, right epididymal tail, no<br />

difference in the concentration of viable sperm, only slight<br />

but sign. reduced sperm motility at 30000 ppm<br />

females: increased oestrus cycle length from 7500 ppm<br />

Reliability : (1) valid without restriction<br />

Flag : Critical study for SIDS endpoint<br />

Route of admin. : oral feed<br />

Exposure period : 13 w<br />

Frequency of treatm. : daily<br />

Duration of test : 13 w<br />

Doses : 0, 625, 2500, 10000 ppm<br />

Control group : yes, concurrent no treatment<br />

Result : No findings<br />

Method : other: determination of sperm motility and concentration in males and<br />

length of oestrus cycle and vaginal cytology following repeated dose<br />

bw; f: 0, 27, 95, 268, 886, 2570 mg/kg bw)<br />

Control group : yes, concurrent no treatment<br />

Result : male, 30000 ppm: increased right testes weight without histopathologic<br />

correlate<br />
