[Relation of pale tongue, purple tongue and TXA2-PGI2 regulation system].

This paper analysed the relationship between pale tongue, purplish tongue and TXB2, 6-keto-PGF1 alpha levels in plasma of 70 cases with coronary heart disease (CHD) and 45 normal subjects. The results showed the following characteristics: The pale tongue group (217.76 +/- 30.5 pg/ml) showed no significant difference in TXB2 level compared with the normal group (164.49 +/- 10.85 pg/ml, P greater than 0.05), while both showed significant difference compared with the purplish tongue group (360.1 +/- 31.3 pg/ml) and that with purple spots (485.07 +/- 106.1 pg/ml, P less than 0.01). The pale tongue group (179.29 +/- 9.08 pg/ml) showed a significant difference in 6-keto-PGF1 alpha level compared with the normal group (244 +/- 19.31 pg/ml, P less than 0.01), but it showed no significant difference compared with the purplish tongue group (185.08 +/- 17.07 pg/ml) and that with purple spots (229.3 +/- 33.2 pg/ml, P greater than 0.05). The comparison between the groups of purplish tongue and that with purple spots and the normal group showed no significant difference (P greater than 0.05). The pale tongue group (1.33 +/- 0.18) showed a marked difference in TXB2/6-keto-PGF1 alpha ratio compared with the normal group (0.72 +/- 0.04, P less than 0.01), the purplish tongue group (2.12 +/- 0.22, P less than 0.01) and that with purple spots (2.25 +/- 0.55, P less than 0.05). The purplish tongue group and that with purple spots showed significant difference compared with the normal group (P less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
